Private equity creates a specific kind of sales tax problem. A founder-led business that’s been operating for ten years without a dedicated tax function gets acquired. The deal closes. The PE firm installs a new CFO, sets EBITDA targets, and starts driving growth into new markets, new states, new products. The compliance infrastructure from the prior ownership doesn’t scale. And nobody on the deal team is thinking about sales tax, because the diligence team looked at it closely and moved on.

That’s the gap. Sales tax compliance at a PE-backed company isn’t a one-time diligence exercise. It’s an ongoing operational requirement that changes every time the company enters a new state, adds a product line, makes an add-on acquisition, or crosses an economic nexus threshold. And because the average PE holding period has stretched to a record 6.6 years as of 2025, there’s a lot of time for exposure to accumulate between deal close and exit.

This article lays out the compliance framework PE firms should be building and maintaining across their portfolio companies from day one of ownership through exit. You’ll learn why portcos are uniquely exposed, what the first 90 days after close should actually cover, how add-on acquisitions reset the compliance clock, and what exit readiness looks like when the next buyer’s diligence team starts pulling records.

The Compliance Gap PE Creates Without Meaning To

Portfolio companies carry structurally elevated sales tax risk compared to other businesses. This isn’t about blame or bad actors. It’s about mechanics. Three dynamics specific to PE ownership drive the exposure.

Growth acceleration outpaces compliance. PE firms buy companies to grow them. That growth creates nexus obligations faster than most portco finance teams can track. New territories, new sales channels, new products, add-on acquisitions. A company that had nexus in five states at acquisition may have nexus in fifteen states two years later. If nobody is monitoring thresholds and updating registrations in real time, the gap compounds with every quarter.

The math is straightforward. A portco growing 25% annually will cross economic nexus thresholds in new states simply through organic growth. Add a new sales channel or geographic expansion initiative, and the pace accelerates. The finance team that was adequate for the pre-acquisition business often lacks the bandwidth to track these changes while also hitting the operational targets the PE firm set at close.

Prior ownership left infrastructure gaps. Most founder-led businesses that get acquired by PE were not running institutional-grade tax compliance. They filed where they knew they had to file, configured their ERP or billing system once, and moved on. The configuration that was accurate for a $15M company selling in three states is almost never accurate for a $50M company selling across the country.

This isn’t a criticism of founders. It’s a recognition that compliance infrastructure scales differently than revenue. A founder who built a successful business made rational decisions about where to invest time and resources. Sales tax compliance rarely made that list until it became a problem. The PE firm inherits whatever infrastructure existed, and that infrastructure was built for a different company at a different scale.

The holding period is long enough for everything to change. With average PE hold periods now exceeding six years, the regulatory environment a company enters at acquisition is genuinely different from the one it exits into. States that didn’t tax SaaS now do. Economic nexus thresholds that didn’t apply at acquisition now apply. Digital goods rules that didn’t exist at close now create filing obligations in multiple new states.

A compliance setup that was correct at acquisition can be materially wrong at exit through no deliberate failure, just the passage of time. Louisiana’s H.B. 8, Washington’s S.B. 5814, Illinois eliminating transaction thresholds entirely. These changes happened during holding periods that started before the rules changed. The portco that doesn’t actively monitor rule changes accumulates exposure silently.

What Closes on Day One (And What Doesn’t)

The deal closes. Diligence is done. The transition services agreement is running. Here’s what doesn’t automatically resolve at close.

Historical exposure from the acquired entity. If diligence identified sales tax exposure, that exposure doesn’t disappear at close. Unregistered states, unfiled periods, misconfigured taxability. VDAs negotiated as post-close obligations need to be filed, often within a defined timeframe from the purchase agreement.

This is one of the most commonly dropped balls in post-close integration. The PE firm negotiated a VDA right in the deal terms and then nobody executes it. The deal team moves on to the next transaction. The integration team is focused on operational priorities. The VDA filing deadline passes, and the company loses the ability to resolve historical exposure on favorable terms.

For a deeper look at how buyers should approach diligence before close, see our guide for M&A buyers navigating sales tax due diligence.

Registration transfers and updates. In most states, sales tax registrations don’t automatically transfer with an acquisition. The acquired entity may need to deregister under prior ownership and re-register under the new entity structure. This varies significantly by deal structure. Asset purchase versus stock purchase creates different obligations. And it varies by state.

Getting this wrong means filing under the wrong entity, which creates its own audit exposure. The state sees returns filed by an entity that no longer owns the business. Or the state sees no returns filed at all because the registration lapsed during the transition.

Combined nexus footprint. The buyer’s existing operations and the acquired company’s operations now need to be evaluated together. If the PE firm’s existing portfolio company had employees in six states, and the newly acquired company had inventory in four of those states but wasn’t registered there because it didn’t have employees, the combined entity now has overlapping nexus that wasn’t visible in either company’s standalone analysis.

This is especially relevant for platform acquisitions where the PE firm already has a portco in the same industry. The combined footprint may trigger nexus in states where neither entity individually had sufficient presence.

The integrated ERP and billing system. Post-close, finance teams are almost always consolidating systems. Migrating the acquired company to the platform’s ERP, standardizing the chart of accounts, integrating billing. Every one of those migrations is an opportunity for taxability configuration to break silently.

The Avalara or Vertex setup that was working before the migration may be calculating incorrectly after, with no error messages and no flags. The product codes that mapped correctly in the old system may not map correctly in the new one. The exemption certificates that were linked to customer accounts may not transfer with the customer data.

What the First 90 Days Should Actually Cover

The post-close period is when compliance infrastructure either gets built or gets deferred. Deferral compounds. Here’s what the first 90 days should actually cover.

Execute Any VDAs Negotiated in the Purchase Agreement

If the purchase agreement included the right to file VDAs for pre-close exposure, initiate those filings immediately. The window to qualify for anonymous VDA status closes once the company is formally registered under new ownership in those states. Don’t wait.

VDAs filed within the first 60 days of close typically preserve the most favorable treatment. Once the company registers in a state, the option to file anonymously disappears. Once the state initiates contact, the option to file at all may disappear.

Learn more about VDAs and registration strategies and when each approach makes sense.

Map the Combined Nexus Footprint

Run a nexus study that includes both the acquired entity’s historical activity and the buyer’s existing operations by state. Identify every state where the combined entity has physical or economic nexus. Cross-reference against where you’re currently registered. The gap is your priority list.

This analysis should include:

• Physical presence (employees, offices, inventory, equipment)
• Economic nexus thresholds by state (revenue and transaction counts)
• Affiliate nexus considerations for related entities
• Marketplace facilitator relationships that may affect filing obligations

Our nexus calculator can help identify where thresholds have been crossed.

Transfer, Update, or Establish Registrations

For every state in the combined nexus footprint where you’re not properly registered under the new entity structure, initiate registration. Some states require deregistration of the old entity before the new one can register. Sequence matters.

Build a registration timeline that accounts for state processing times. Some states process registrations in days. Others take weeks. If the portco is actively selling into a state where it has nexus but isn’t registered, every day of delay is a day of exposure accumulation.

Audit the Taxability Configuration in the Billing/ERP System

Before you migrate anything to a new system, and even if you’re not migrating, pull a sample of transactions and verify that the taxability logic is producing correct results under current rules.

Pay particular attention to:

• States where taxability rules changed recently
• Product lines that were added or repriced in the 12 months before close
• Customer types that may qualify for exemptions
• Bundled products or services where taxability varies by component

A 50-transaction sample across different product types, customer types, and states will surface most configuration errors. If errors appear in the sample, a full audit is warranted.

Validate Exemption Certificate Files

Request the acquired company’s exemption certificate files. Assess completeness, currency, and state appropriateness. If certificates are stored in email threads or filing cabinets rather than a centralized system, remediate immediately.

An auditor’s first request is always the cert file. A 30-40% deficiency rate in exemption certificate files is common, and every missing or expired certificate is a potential assessment.

Establish a Nexus Monitoring Cadence

Economic nexus thresholds change as the business grows. Set a quarterly review process, at minimum, to check whether the combined entity has crossed new thresholds since the last review.

This is especially important in growth-mode portcos where revenue in new states can cross thresholds faster than the finance team is watching. A state that was well below threshold in Q1 may be above threshold by Q3 if a new sales initiative is working.

Document Everything

The PE firm will eventually exit this company. The next buyer’s diligence team will want to see a clean compliance record from the date of acquisition forward. Building that record from day one, rather than reconstructing it before exit, is dramatically less expensive.

Documentation should include:

• Nexus analysis and conclusions by state
• Registration dates and entity details
• VDA filings and resolution letters
• Taxability configuration decisions and rationale
• Exemption certificate audit results and remediation steps
• Quarterly monitoring results

Every Add-On Acquisition Resets the Clock

PE firms often pursue buy-and-build strategies. Acquire a platform, then add smaller companies to expand capabilities, customer base, or geographic reach. Each add-on creates the same compliance reset described above, and the complexity compounds.

Each add-on acquisition is a new nexus analysis, a new registration review, a new exemption certificate audit, and a new opportunity for misconfigured taxability to enter the combined entity’s compliance posture.

The challenge is that add-ons often close faster and with less diligence resources than the platform acquisition. The PE firm is in deal mode. The integration team is stretched. The compliance work gets deferred.

What deferred looks like in practice: The add-on’s ERP gets folded into the platform’s system without anyone verifying that the acquired company’s taxability settings were correct. The acquired company’s registrations lapse during the transition. Exemption certificates from the acquired company’s customer base never get migrated to the centralized system.

Two years later, when a state auditor pulls the combined entity’s records, the compliance history has gaps that map directly to each add-on close date. The auditor sees the acquisition date, sees the compliance gap that started at that date, and draws the obvious conclusion.

The fix is process-level. Every add-on acquisition should trigger the same 90-day compliance checklist as the platform acquisition. Not abbreviated, not deferred. The same checklist, executed with the same urgency.

Building that into the integration playbook before the first add-on closes is the right time to do it. The operating partner who establishes the standard before the first add-on has a repeatable process. The operating partner who tries to establish the standard after the third add-on has three different compliance postures to reconcile.

For sellers preparing a company for acquisition, our guide for M&A sellers covers how to present a clean compliance record to buyers.

What “Staying Current” Actually Requires

Sales tax compliance isn’t a project. It’s a function. Between close and exit, these are the things that need active management.

Nexus threshold monitoring. Economic nexus thresholds must be checked quarterly at minimum. Revenue growth, new sales channels, and new customer geographies can push a portco across thresholds in new states with no visible trigger.

The finance team needs a process for this, ideally automated through their tax platform, not a spreadsheet someone updates annually. The portco that discovers it crossed a threshold 18 months ago has 18 months of exposure to address. The portco that discovers it crossed a threshold last quarter has one quarter.

Taxability rule changes. Digital goods rules, SaaS taxability, and specific industry exemptions change by state legislative session. A quarterly review of rule changes in states where the portco has nexus should be on someone’s calendar.

This is especially important for portcos selling SaaS, digital products, or services. These are the fastest-changing areas of sales tax law. A taxability determination that was correct two years ago may be incorrect today, and the ERP system won’t update itself.

Exemption certificate renewal. Certificates expire. States have different renewal schedules. A certificate that was valid at acquisition may be expired by year two of the hold.

If the portco’s exemption certificate management isn’t automated, someone needs to own the renewal calendar. Proactive renewal requests to customers are dramatically more effective than scrambling to collect certificates during an audit.

Return filing accuracy. Beyond just filing returns on time, someone needs to periodically reconcile what was collected against what was remitted.

The double-remittance problem (filing your own returns in states where Amazon or another marketplace is already remitting) is common in PE-backed e-commerce portcos. A quarterly reconciliation catches these before they compound into material overpayments.

Staff transition planning. PE-backed companies have high controller and CFO turnover. When the person who set up the compliance infrastructure leaves, the institutional knowledge leaves with them.

Build the compliance framework into documented processes, not individual expertise. The next controller should be able to pick up the compliance function from documentation, not from asking the person who left what they were doing.

What the Next Buyer’s Diligence Team Will Find (And How to Get Ahead of It)

The PE firm that built a clean compliance record from day one of ownership is selling a fundamentally different asset than the firm that deferred compliance work and is now racing to fix it before the buyer’s diligence team arrives.

Quality of Earnings providers have gotten more sophisticated about sales tax. The QofE team will look at nexus, registrations, filing history, and exemption certificates. Material exposure will show up in the report. Material exposure that shows up in the report will affect the deal.

What the next buyer will look at, and what should be clean before the process starts:

Registration completeness. Is the portco registered in every state where it has nexus? Any gap is a liability the buyer will price against the deal. The buyer’s diligence team will run their own nexus analysis and compare it against your registration list. Gaps will be flagged.

Filing history. Are returns filed, on time, in every registered state for the entire holding period? Missing returns, even zero-dollar returns, are audit flags. Late filing penalties accumulate. A pattern of late filings signals operational weakness.

Exemption certificate files. Are certificates current, complete, and appropriately documented? A 30-40% deficiency rate in exemption certificate files, which is common, is a meaningful audit risk the buyer will flag. The buyer will estimate the potential assessment from missing certificates and factor it into their valuation.

VDA history. Were VDAs for pre-close exposure actually filed and resolved? The buyer will want to see that any historical issues identified in the original diligence were addressed, not just disclosed and deferred. Resolution letters from states are the documentation that matters.

Taxability configuration audit trail. Is there documentation showing that taxability rules were reviewed and updated as state laws changed? This matters especially in states that made significant changes during the hold period. The buyer wants to see that someone was paying attention, not that the system was set once and never reviewed.

The ideal timing for a pre-exit compliance review is 12-18 months before the expected exit process. That leaves enough runway to file VDAs for any remaining exposure, remediate registration gaps, and build a compliance record that holds up to buyer scrutiny.

Six months before launch is technically possible but creates deal risk if issues are material. Three months before is too late for anything but disclosure.

The Compliance Framework That Protects Value Across the Hold

Sales tax isn’t what PE firms think about when they’re building value. But it’s what buyers look at when they’re deciding what a company is worth.

The portco that enters a sale process with a clean, documented compliance record negotiates from strength. Registrations complete. Returns filed. Certificates current. Historical issues resolved. The QofE report comes back clean on sales tax, and the buyer moves forward without pricing in compliance risk.

The portco that discovers material exposure during buyer diligence negotiates from weakness. At exactly the moment when leverage matters most.

The framework isn’t complicated. It’s a day-one nexus assessment. A 90-day integration checklist executed with discipline. A quarterly monitoring cadence that catches threshold crossings and rule changes before they compound. A pre-exit cleanup review 12-18 months before the process launches. And documentation throughout that tells the story of intentional compliance management, not reactive scrambling.

The operating partner who builds this framework once can deploy it across the portfolio. The portco CFO who inherits it has a foundation that scales with growth rather than breaking under it.

We’ve built this with PE firms and their portfolio companies across the full holding period. Platform acquisitions through add-ons through exit. The Rent-A-Center/Acima transaction. Growth-stage SaaS companies expanding into new states faster than their finance teams could track. Manufacturing roll-ups where every add-on brought a different compliance posture.

The work is the same every time. Assess nexus. Map registrations. Audit taxability. Clean up certificates. Monitor changes. Document everything. The companies that do it from day one exit cleanly. The companies that defer it spend the months before exit fixing what could have been prevented.

If you’re an operating partner building shared services infrastructure across a fund’s holdings, or a CFO managing compliance under institutional ownership for the first time, the starting point is the same. Understand where you are. Understand where the gaps are. Build a plan to close them.

Sales tax is the obligation that catches finance leaders off guard. Not because the concept is difficult to grasp, but because the operational reality of managing it correctly across multiple states, multiple products, and a growing business turns out to be significantly more complex than most CFOs realize until something goes wrong.

Most finance leaders pick up their first real understanding of sales tax compliance in one of three ways: they receive a notice from a state they didn’t know they were supposed to be filing in, they inherit a compliance setup from a previous finance team and have no idea whether to trust it, or they go through a transaction and a diligence team surfaces exposure nobody knew existed. A fundraise, an acquisition, a sale process: these are the moments when years of quiet misconfiguration suddenly become very expensive.

This article is the orientation that should come earlier. You’ll learn what sales tax compliance actually requires at a strategic level, which decisions belong on your desk and which can safely live elsewhere, and how to recognize when your current setup isn’t working before a state notice forces the conversation. If you’ve ever felt like you should understand this function better than you do, you’re in the right place.

A Finance Leader’s Honest Orientation to the Function

Sales tax is a transaction-level obligation. Every time a customer buys something from you, some states require you to collect tax from that customer and remit it to the state. The obligation exists in the states where you have nexus, which is the legal connection between your business and a state that creates a tax responsibility. Nexus can come from physical presence (offices, employees, inventory, trade show attendance) or from economic activity alone (crossing a state’s revenue or transaction threshold).

The economic nexus standard became universal after the Supreme Court’s 2018 South Dakota v. Wayfair decision. Before Wayfair, a business generally needed physical presence in a state to trigger sales tax obligations. After Wayfair, states can require you to collect and remit sales tax based purely on your sales volume into that state, typically once you cross $100,000 in revenue or 200 transactions. This means a company with no employees, no offices, and no inventory in a state can still owe that state sales tax if enough customers live there.

What makes this genuinely complex for a CFO is the combination of four things that don’t exist anywhere else in the tax code. First, it varies by state in ways that are hard to systematize. Second, it’s entirely self-assessed and self-reported, meaning no one tells you when you’ve crossed a threshold. Third, it’s calculated on gross revenue rather than profit, so losses don’t reduce exposure. Fourth, the penalty structure for non-compliance includes both uncollected tax and interest and penalties that accrue from the date the obligation started, not the date anyone discovered it.

The practical implication is this: unlike income tax, where the IRS sends you a return and you respond, sales tax requires your organization to proactively determine where you have obligations, register, configure your systems correctly, file returns on time, and keep everything current as the business changes. Nothing about that process is automatic. Someone has to own it.

What You Need to Know Before You Can Delegate Anything

Before you can appropriately resource or delegate the sales tax function, you need to personally understand three foundational questions. These aren’t operational details. They’re the strategic orientation that determines whether your compliance posture is sound or whether you’re carrying exposure you don’t know about.

Where Do We Actually Have Nexus Right Now?

This is the single most important question in sales tax compliance, and most CFOs at growing companies can’t answer it with confidence. The honest answer requires a current nexus analysis. Not a list of states where you have offices, but a systematic mapping of physical presence and economic nexus thresholds against your actual sales data by state.

The nexus footprint changes constantly. Every new remote hire, every trade show, every state where revenue crosses $100K, every Amazon fulfillment center that stores your inventory: each creates a new nexus obligation. If your last nexus analysis was done at implementation of your tax software or at a prior fundraise, it’s out of date.

Use The Sales Tax People’s nexus calculator to get a preliminary read. A meaningful analysis requires transaction-level data and a professional review, but the calculator tells you quickly whether you have obvious gaps.

Are We Correctly Configured to Collect the Right Amount?

Nexus and registration answer the question of where you have obligations. Configuration answers the question of whether you’re calculating correctly in those states. A business can be registered everywhere it should be and still be systematically over-collecting or under-collecting because its product taxability rules, exemption certificate logic, or address sourcing are wrong.

This is the Avalara misconfiguration problem. The software is running, returns are filing, everything looks fine, and the calculations have been wrong since go-live. For a CFO, the right question isn’t “do we have automation software” but “has anyone with sales tax expertise ever audited whether the configuration produces correct results.” Most companies have not done this. Our article on Avalara misconfiguration explains how this happens and what to look for.

Is the Team or Provider Actually Managing the Function?

Filing returns is the most visible part of sales tax compliance. It’s also the smallest part. The function also includes monitoring nexus thresholds, updating registrations as the business changes, managing exemption certificate validity, reconciling marketplace sales against direct-channel filings, keeping product taxability current as product lines evolve, and responding to state notices.

Many companies have someone “handling sales tax” who is in practice only filing returns and handling none of the rest. That’s the most common gap we encounter. The person or provider doing the work may be excellent at what they do, but if their scope is limited to return preparation, the strategic layer of the function is unowned.

The Right Division of Responsibility

Sales tax compliance has a clear division between strategic decisions that require judgment and executive accountability, and operational tasks that are genuinely delegable to a team member or an outside provider. Conflating the two is how both under-delegation (the CFO spending time on return filings) and over-delegation (nobody noticing that the nexus footprint has expanded) happen simultaneously.

The decisions in the left column are the ones that surface unexpectedly in board meetings, diligence reviews, and audit defense situations. A CFO who hasn’t thought through these doesn’t have a compliance problem yet. They have a compliance gap that will become a problem at the worst possible moment.

If you’re looking at the left column and realizing you haven’t made explicit decisions about some of these items, that’s normal. Most CFOs haven’t. The point isn’t to create anxiety. It’s to clarify what actually requires your judgment versus what can safely run without your involvement.

Build, Buy, or Outsource: A Framework for Different Company Stages

Sales tax compliance can be resourced in three ways, and the right answer changes as the company grows.

Software Plus Internal Ownership

A tax automation platform (Avalara, Vertex, TaxJar, and others) handles calculation and filing. Your internal finance team owns configuration, monitoring, exemption certificates, and everything else.

This works at smaller companies with simple product catalogs, few states, and a finance team member with bandwidth and some tax knowledge. It breaks down when the business grows faster than the team’s capacity to keep the configuration current.

For a full evaluation of what to look for in a tax automation platform, the companion guide covers this in detail.

Software Plus Specialized Oversight

The automation platform handles mechanics. A sales tax specialist, either an internal hire with state and local tax expertise or an outside advisory firm, owns the strategic layer: nexus analysis, taxability research, configuration audits, and escalation on complex questions.

This is the right model for mid-market companies with complex product mixes, multi-state footprints, or significant change velocity (new products, new markets, acquisitions). It separates the operational burden from the judgment layer.

Fully Managed Service

An outside provider handles the entire function end-to-end: registration, configuration, filing, certificate management, nexus monitoring, and audit response. The CFO’s involvement is periodic review and escalation for genuinely strategic decisions.

This is appropriate when the internal finance team doesn’t have sales tax expertise, when the compliance footprint is large and complex, or when the cost of an internal specialist is hard to justify relative to transaction volume.

The Critical Thing to Understand About All Three Models

Software alone is never sufficient. The automation platform does what it’s configured to do. If nobody with sales tax expertise is periodically reviewing whether the configuration is still correct, whether the nexus footprint is current, and whether the exemption certificate files would survive an audit, the software is generating a false sense of compliance.

The question isn’t which model is best. It’s which model matches your current complexity, your team’s capabilities, and your risk tolerance. And it’s worth revisiting that question every 12 to 18 months as the business changes.

For companies that need help thinking through registration strategy or addressing historical exposure, our VDA and registrations page explains the options.

How to Know If Your Current Setup Is Actually Working

None of these warning signs are proof of a problem individually, but any of them is worth investigating. More than two or three and a configuration review is warranted.

Your effective sales tax rate as a percentage of revenue has been flat for years. A growing, changing business in a correctly configured system produces some rate variation as the product mix and geographic footprint shift. A completely flat rate usually means the configuration isn’t tracking reality.

You’ve never had a sales tax professional review your setup. The accountant who files your returns and handles your income tax is not the same as someone with state and local tax expertise. Generalist accountants file returns. They don’t audit taxability configurations, conduct nexus analyses, or advise on VDA strategy.

You’re registered in the same states you were registered in three years ago, despite meaningful business changes. New hires in new states, trade show attendance, revenue growth into new markets: each of these can create nexus obligations without triggering any visible alert in your current setup.

You have marketplace sales and you’re also filing your own returns in those states. Double remittance is extremely common and almost never caught without a deliberate reconciliation. If Amazon is collecting and remitting as a marketplace facilitator and you’re also including those sales in your own returns, you’re paying the same tax twice.

You’ve launched new products or changed your pricing model since the last time anyone reviewed your taxability configuration. New product lines, new subscription tiers, new bundling: each can change taxability in ways the software won’t flag on its own.

You received a state notice and nobody is sure what triggered it or how to respond. A state notice is a signal that the state’s data shows a discrepancy between what they expect and what you’re doing. The right response is not to file whatever the notice asks for without understanding why.

You couldn’t answer the three questions in section two with confidence. That’s the clearest signal of all.

Why This Is a Finance Leader’s Problem, Not an Accounting Problem

Sales tax compliance ends up on the CFO’s agenda in one of two ways: proactively, because the CFO treated it as a financial risk worthy of the same attention as any other material liability, or reactively, because something surfaced it at the worst possible moment.

The moments where reactive discovery is most expensive: a fundraise where investor diligence surfaces unregistered states; an acquisition where the buyer’s tax team quantifies exposure that drops the valuation; a sale process where the quality of earnings team finds years of incorrect taxability mapping; a state audit that opens during a period of maximum operational distraction.

Sales tax exposure is unusual among financial risks in that it compounds silently. There’s no income statement line that flags it. Returns file. Software calculates. Everything looks fine. The exposure builds at the rate of your revenue in unregistered states, plus penalties and interest, across however many years the gap has been open. A business that discovers a five-year nexus gap is looking at a very different number than a business that caught it at twelve months.

The CFO who treats sales tax as an accounting function to be delegated and forgotten is the one who discovers it at the worst time. The CFO who treats it as a financial risk with a known profile, manageable with the right resourcing and the right periodic review, rarely has an unpleasant surprise.

The Right Time to Get Oriented Was Two Years Ago. The Second Best Time Is Now.

Most of the CFOs we work with didn’t have a crisis. They had a quiet realization that they didn’t actually know whether their compliance setup was working. Maybe it was a question from a board member they couldn’t answer with confidence. Maybe it was a new state notice sitting in someone’s inbox. Maybe it was just the nagging sense that a function this consequential shouldn’t feel this opaque.

The gap between “I think we’re fine” and “I know we’re fine” is exactly where exposure lives. And that gap closes with one conversation.

A What’s Next consultation with our team takes about an hour. It’s not a sales pitch. It’s an honest assessment of where you stand: your current nexus footprint, whether your configuration looks sound, and what, if anything, needs to change. We’ll answer the three questions from section two with specificity. You’ll leave knowing whether your compliance posture is solid or whether there’s work to do.

Some CFOs walk away with confirmation that their setup is working. Others discover gaps they didn’t know existed and get a clear path to address them. Either way, you’ll have the orientation you need to own this function the way you own every other material financial risk.

Just talking should always be free. Schedule your What’s Next call and find out where you actually stand.

A business that set up its digital goods taxability rules in 2023 and hasn’t touched them since is almost certainly misconfigured in at least one state. Probably several.

Sales tax on digital goods is the fastest-moving area of US consumption tax law right now. States that had no digital goods tax two years ago now tax SaaS, streaming, and downloads. States that had partial rules have expanded them. The definitions of what counts as a “digital product” differ by state, change by legislative session, and in some cases turn on factors as specific as whether the buyer gets a permanent right to use the product or just temporary access.

For SaaS companies, streaming platforms, software businesses, and any e-commerce seller dealing in digital products, the practical question isn’t whether the law has changed. It’s whether your compliance setup has kept pace.

This article explains how states categorize digital goods, which states made material changes in 2025 and 2026, and what that means for businesses that set their taxability rules before any of this happened. You’ll get a clear framework for understanding how different states approach digital goods taxation, a breakdown of the most consequential legislative changes including Louisiana’s H.B. 8 and Washington’s S.B. 5814, and a practical audit checklist to identify where your current configuration may be creating silent exposure.

The Problem With Taxing Something You Can’t Touch

Sales tax was built for physical goods. Every state has decades of statutory and case law defining what tangible personal property is and when it’s taxable. Digital products don’t fit that framework cleanly, so states have taken wildly different approaches to bringing them into the tax base.

There is no federal standard for digital goods taxation. Each state defines the category independently, taxes it differently, and updates those rules on its own schedule. The result is a patchwork where the same SaaS subscription can be taxable in Texas, exempt in California, taxable at a reduced rate in Connecticut, and in a genuinely ambiguous gray zone in several others.

The three broad categories states are working with are the ones your taxability configuration needs to get right.

Downloaded digital goods are products delivered as a file the buyer keeps. Think software purchased as a perpetual download, ebooks, music files, and digital games. Most states treat these as the closest analog to tangible personal property and tax them more broadly than other digital categories. More than 30 states tax downloaded software.

Streaming and subscription access covers content accessed remotely but not downloaded. Netflix, Spotify, cloud-hosted software, and SaaS subscriptions fall into this bucket. These are treated as services in most states, which means they fall outside traditional sales tax in states that don’t tax services. But that’s changing. Streaming services are taxable in more than 30 states in 2026, up significantly from five years ago.

SaaS and cloud software includes software accessed over the internet without a local installation. This is the most contested category. As of 2025, approximately 25 states tax SaaS in some form, with significant variation in how they define and apply the tax.

The distinction between these three categories matters because a single product can be taxed differently depending on which part of it a state is looking at. A software platform that lets users download a desktop client and also access a browser-based version may face different taxability treatment for each component.

The States That Moved the Line (And What They Changed)

Digital goods taxability rules changed in at least eight states during 2025 and 2026. These are the most consequential for digital businesses.

Louisiana: January 1, 2025

The biggest single expansion of digital goods taxation in recent years. Louisiana’s H.B. 8, signed in December 2024, brought SaaS, digital products, and information services into the state’s sales tax base effective January 1, 2025.

The law defines “digital products” broadly to include digital audiovisual works, digital audio works, digital books, digital codes, digital applications and games, digital periodicals, and any other otherwise taxable tangible personal property transferred electronically. That applies whether the product is downloaded, streamed, or accessed by subscription. SaaS is explicitly covered as “prewritten computer software access services.”

For businesses selling digital products to Louisiana customers, this created a new obligation retroactive to Q1 2025. If you had Louisiana nexus before January 2025 and weren’t collecting, that exposure needs to be quantified and addressed.

Washington: October 1, 2025

Washington’s S.B. 5814 is one of the most significant expansions of sales tax to digital services in any state in recent years. Unlike Louisiana, which added digital products to an existing sales tax framework, Washington’s change brought entirely new service categories into the retail sales tax for the first time.

Effective October 1, 2025, the following service categories became subject to Washington sales tax for the first time: IT services including technical support, training, consulting, and data entry; custom software development and customization of prewritten software; website design and development; advertising services including digital advertising, search engine marketing, and online referrals (excluding newspapers, broadcast, and billboards); and digital automated services with human effort, a category previously excluded.

The practical impact: technology companies, digital agencies, custom software developers, and IT service providers doing business in Washington needed to begin collecting retail sales tax on October 1, 2025 on services they had never previously had to tax. Many companies in this category had never registered in Washington at all, because their prior service offerings weren’t subject to Washington sales tax.

Washington already taxed digital goods broadly before this change. Downloaded, streamed, and subscription-based digital products were largely taxable under Washington’s pre-existing digital automated services rules regardless of access method or whether the buyer had permanent or temporary use rights. The October 2025 expansion added new service categories on top of that already-broad foundation.

States Actively Expanding Definitions in 2025 and 2026

Several additional states updated guidance or expanded definitions without passing major new legislation. Virginia introduced but has not yet enacted a digital goods tax bill in January 2026. Illinois tightened economic nexus rules affecting digital sellers. Others reviewed or clarified SaaS taxability through administrative guidance.

The Broader Trend

Digital product taxability rules moved in one direction across all state activity in 2025 and 2026: toward broader coverage. No state reduced digital goods taxation during this period. The trajectory is clear. Businesses that assumed digital goods exemptions would persist are working against the current.

How States Think About Digital Goods (And Why It Matters for Your Setup)

Beyond the specific legislative changes, there are a few conceptual tests that drive how most states classify digital goods. Understanding them helps you reason about any state’s rules, not just the ones covered in this article.

The Permanent Right-to-Use Test

Several states tax digital goods only when the buyer receives a permanent right to use the product, not just temporary access. Idaho and Indiana both use this approach.

A one-time software purchase is taxable. A subscription to the same software is not. This distinction creates planning opportunities but also compliance traps. Businesses that sell both perpetual licenses and subscriptions may need different taxability treatment for the same product depending on which pricing model the customer chose.

The Delivery Method Test

Some states tax digital goods based on how they’re delivered, not what they are. Colorado taxes ebooks stored on a flash drive but not the same ebook delivered electronically. The distinction hinges on whether the product is ultimately manifested in a tangible form.

The True Object Test

This test is used in states where the taxability question is ambiguous. If the true object of the transaction is a taxable good like software or media, the whole transaction is taxable, even if bundled with exempt services. If the true object is an exempt service, the whole transaction may be exempt.

Bundled SaaS offerings that include consulting, onboarding, or other service components need particular scrutiny under this test. The way you structure and describe your offering can determine whether the entire transaction is taxable or exempt.

The Tangible Personal Property Analog

Several states have broad definitions that treat digital goods as equivalent to their tangible counterparts. Alabama, Kentucky, and Texas all take this approach. Texas explicitly states that delivering an item electronically does not change its tax status. If the physical version would be taxable, so is the digital version.

Quick-Reference Framework Table

California deserves a specific note here. It remains the most significant holdout, exempting SaaS and streaming from sales tax at the state level. Discussions about changing this have been ongoing, and the state’s $500K economic nexus threshold means businesses may have nexus there from sales volume alone even if they’re not collecting tax on digital goods.

If Your Taxability Setup Predates 2025, You Probably Have a Problem

Most businesses selling digital products configured their taxability rules when they first set up sales tax compliance. Whether through Avalara, Vertex, TaxJar, or manual configuration in their billing system, that configuration reflected what was true at that point in time.

The problem is that digital goods taxability rules have changed faster than any other category. A setup that was accurate in 2022 or even 2024 may be systematically undertaxing or overtaxing in multiple states today. And because the software calculates something for every transaction without flagging whether the underlying rules have changed, the errors compound silently.

Here are the specific risk areas to evaluate.

Louisiana customers billed before Q1 2025. If you were not collecting on Louisiana sales of SaaS or digital goods before January 2025 and you had nexus there, you have a historical exposure question that needs evaluation. A Voluntary Disclosure Agreement (VDA) can limit look-back and waive penalties, but only if you address it proactively.

Washington IT and digital services since October 2025. If your company provides IT services, custom software development, website development, advertising services, or any of the other categories added by S.B. 5814, and you have Washington nexus, you’ve been required to collect retail sales tax on those services since October 1, 2025. If you haven’t been, that’s an exposure that needs to be addressed.

Subscription vs. download split treatment. If your billing system doesn’t distinguish between perpetual downloads and subscription access, you may be applying uniform taxability where the rules require split treatment. That means over-collecting in some states and under-collecting in others.

Bundled offerings. SaaS products bundled with onboarding, consulting, or professional services often get taxed as all-or-nothing when they should be split. The bundled transaction rules vary by state and most tax software requires explicit configuration to handle them correctly. This is one of the most common sources of taxability mapping errors in Avalara and similar platforms.

Streaming platforms. If you operate a streaming or subscription media service and haven’t audited your state taxability matrix since 2023, the landscape has changed materially. More than 30 states now tax streaming.

What to Check Before You Assume Your Configuration Is Current

A digital goods taxability audit doesn’t require starting over. It requires checking specific things systematically.

Map your product categories against state-specific rules. For every digital product or service type you sell, identify which of the three major categories it falls into: downloaded goods, streamed/subscription access, or SaaS. Then check each state where you have nexus against its current rules for that category. States where you’re registered but haven’t verified the taxability rules for digital goods since 2024 should be reviewed in full.

Check Louisiana specifically if you sell SaaS or digital products. Louisiana’s January 2025 change is the most significant single shift in digital goods taxation in recent years. If you had Louisiana nexus before January 2025 and weren’t collecting, that exposure needs to be quantified and addressed. A VDA can limit look-back and waive penalties. If you began collecting after January 2025, verify that your taxability configuration correctly covers all the digital product types Louisiana’s law enumerates.

Check Washington if you provide IT or digital services. If your service offerings include anything added by S.B. 5814, verify that your Washington taxability configuration was updated for October 1, 2025, and that you’ve been collecting since that date. If you weren’t previously registered in Washington because your prior services weren’t taxable there, that registration gap needs to be addressed.

Review your product bundling logic. Pull a sample of your invoices for customers in states with complex digital goods rules. Are bundled offerings being taxed correctly? Are you splitting service and software components where required? Are you applying the permanent right-to-use distinction in states that require it? If you can’t answer these questions confidently, your configuration likely needs review.

Verify that new products launched since your last configuration review are correctly mapped. Any product launched or repriced after your last taxability review is at risk of being mapped to a generic or incorrect tax code. This is especially true for new tiers, add-on modules, or feature bundles that changed the nature of what you’re delivering.

Check economic nexus in the states that changed their rules. A state that changed its digital goods taxability may also have changed or clarified its economic nexus rules for digital sellers. Verify that your nexus footprint accounts for current thresholds. Use our nexus calculator to check not just the states that changed rules, but any state where you’ve crossed $100K in digital goods sales.

The Rules Changed. The Question Is Whether Your Setup Did.

Digital goods taxation in 2026 looks meaningfully different from 2024. Louisiana added SaaS and digital products to its tax base through H.B. 8. Washington expanded its already-broad digital goods coverage and brought entirely new IT and digital service categories into the retail sales tax for the first time through S.B. 5814. The trend across every state that touched digital goods rules moved in one direction: toward broader coverage. And the businesses most exposed aren’t the ones that ignored compliance. They’re the ones that set it up once and trusted it to stay current.

The silent nature of these errors is what makes them dangerous. Your tax software calculates something for every transaction. It doesn’t flag that the rules in Louisiana changed six months ago, or that your bundled SaaS offering should be split-taxed in Connecticut, or that your IT services are now taxable in Washington. The calculations keep running. The exposure keeps building.

A taxability analysis for digital goods takes the current rules in every state you sell into, applies them to your actual product catalog, and tells you where you’re correctly configured and where you’re not. That analysis is what turns “we think we’re compliant” into knowing you are. It identifies Louisiana exposure before an auditor does. It catches the subscription vs. download split treatment your billing system is handling incorrectly. It surfaces the bundled offering that’s been overtaxed in three states and undertaxed in two others.

For businesses selling SaaS, streaming services, software downloads, IT services, or any digital products across multiple states, the cost of a taxability review is a fraction of the cost of discovering these issues during an audit. And unlike audit defense, a proactive review gives you options. VDAs can limit look-back periods and waive penalties, but only if you address exposure before a state finds it first.

The practical next step is a conversation. Not a sales pitch, but a straightforward assessment of your current setup against the 2025 and 2026 changes. We’ll look at your product mix, your state registrations, and your existing taxability configuration. You’ll leave with clarity on where you stand and what, if anything, needs to change.

When you signed up for Amazon FBA, the pitch was simple: send your inventory to Amazon, and they handle the rest. Storage, picking, packing, shipping, and yes, sales tax collection too. Amazon collects and remits sales tax on your behalf in every state that requires it. The returns, the remittances, all of it. Done.

So why does a growing number of FBA sellers get letters from state tax authorities they’ve never registered in?

Because “Amazon collects sales tax on your sales” and “you have no sales tax obligations” are not the same thing. Amazon’s marketplace facilitator status covers the transaction. It doesn’t cover the fact that your inventory is sitting in a warehouse in Pennsylvania or Texas or New Jersey. A warehouse you never chose, in a state you may have never sold to directly. That inventory is creating physical nexus. And physical nexus creates obligations Amazon doesn’t handle for you.

This article explains exactly how FBA inventory nexus works, what it means for your business, and what to do about it. You’ll learn how to find out which states your inventory has touched, what compliance obligations that creates, and how to address any historical exposure before a state reaches out to you first.

Amazon Handles the Tax Collection. It Doesn’t Handle Your Nexus.

Amazon is a marketplace facilitator. Under laws now in effect in all 45 sales tax states, Amazon is required to collect and remit sales tax on sales made through its platform. That means for every order a customer places on Amazon.com, Amazon calculates the correct rate, collects it at checkout, and sends it to the state. You don’t do any of that. It happens automatically.

This is genuinely useful. It eliminates the collection and filing burden for your Amazon channel sales in most states.

But here’s what marketplace facilitator laws do not do:

They don’t register you in any state. They don’t eliminate your nexus in states where Amazon stores your inventory. They don’t cover sales you make through any channel other than Amazon, including your Shopify store, your own website, wholesale orders, or any other platform. And in many states, they don’t eliminate your obligation to file returns, even returns showing zero tax due.

Amazon handles the transaction. Your nexus footprint is your problem.

Your Inventory Is in States You Never Chose. That’s the Problem.

When you enroll in FBA, you ship your products to Amazon. Amazon then distributes that inventory across its fulfillment network, placing units in warehouses across multiple states to optimize delivery speed to customers. You don’t decide where your inventory goes. Amazon’s algorithms do.

That’s fine for logistics. It’s a problem for sales tax.

Physical nexus is the connection between your business and a state that’s created by physical presence. Inventory sitting in a warehouse is physical presence. In most states, having your products stored in an Amazon fulfillment center, even temporarily, even in small quantities, is enough to establish physical nexus for your business in that state.

A 2025 California ruling confirmed that even minimal FBA inventory constitutes ‘doing business’ in California — triggering the state’s $800 annual LLC franchise tax even for businesses well below California’s economic nexus thresholds.

Amazon operates more than 175 fulfillment centers across the United States. Sellers using FBA typically find their inventory distributed across anywhere from 8 to 20+ states at any given time. Those states shift as Amazon rebalances its network, often without notifying individual sellers.

The key implication: Every state where Amazon has ever stored your inventory is a state where you likely have, or have had, physical nexus. That means registration obligations, return filing obligations, and in some states, income and franchise tax obligations. None of which Amazon handles on your behalf.

Step One: Figure Out Where Your Inventory Actually Is

Amazon provides the data you need. You just have to know where to look.

Log In to Amazon Seller Central

Start by signing into your Seller Central account. All the inventory location data lives in your reports dashboard.

Navigate to Reports and Fulfillment

From the main menu, go to Reports, then select Fulfillment. This is where Amazon stores all your FBA-related data.

Download the FBA Inventory Ledger Report

Download the FBA Inventory Ledger report using the Detail View. This was formerly called the Inventory Event Detail report. Select a date range that goes back to when you first started selling on FBA, not just the current period.

Locate the Fulfillment Center ID Column

Open the file and find the “fulfillment-center-id” column. Each code corresponds to a specific Amazon warehouse location.

Filter or Pivot by State

Map each fulfillment center ID to its state location. Filter or create a pivot table to see every state where Amazon has stored your inventory, and for how long.

The fulfillment center ID codes map to specific warehouse locations. Amazon fulfillment centers in states with major footprints include California, Texas, Pennsylvania, New Jersey, Illinois, Michigan, Georgia, Ohio, and Washington, among others. If your inventory has touched any of those warehouses, you likely have physical nexus there.

Important: Pull this report back to when you first started selling on FBA, not just the current period. Nexus obligations don’t start from when you discovered them. They start from when the inventory arrived.

A note on the moving target: Amazon rebalances inventory regularly. A state that shows zero inventory today may have stored your products last quarter. And new states can appear without warning as Amazon opens new facilities or redistributes stock. This is an ongoing monitoring task, not a one-time check.

Having Nexus Means Having Obligations. Here’s What They Are.

Once you establish that Amazon has stored your inventory in a state, the obligations in that state typically include:

Registration: You need a sales tax permit in that state. Amazon collecting tax on your Amazon sales doesn’t substitute for registration. Many states require sellers with nexus to be registered regardless of whether a marketplace facilitator is collecting on their behalf.

Return filing: Most states where you’re registered require you to file returns, even if Amazon remitted all the tax and your own return shows zero dollars due. These “zero-dollar returns” are not optional. Missing them generates penalties the same way missing a return with tax due does.

Non-Amazon channel compliance: If you sell through your own website, Shopify store, or any other channel into a state where you have nexus, you are responsible for collecting and remitting sales tax on those sales yourself. Amazon’s marketplace facilitator status covers only Amazon. Your Shopify store is entirely your responsibility.

Income and franchise tax: This is the obligation most FBA sellers don’t know about at all. Marketplace facilitator laws cover sales tax only. Physical nexus created by inventory in a state can also create income tax and franchise tax obligations in that state. California’s $800 minimum franchise tax applies to any business with nexus there, regardless of profitability.

Property tax: Some states tax business personal property, including inventory. If your products are sitting in a warehouse in a state with inventory property tax rules, that inventory may be taxable.

The Harder Question: What About the States You’ve Already Been In?

Most FBA sellers who discover the inventory nexus problem aren’t discovering it as a new business. They’re discovering it two or three years into selling, after their inventory has already touched 10 or 15 states they never registered in.

That creates a historical exposure question: what do you owe for the periods before you knew?

A few things to understand:

Sales tax is a gross revenue tax. It’s calculated on what you sell, not what you profit. Exposure compounds across every transaction in every unregistered state for however long inventory was sitting there.

Non-filers face unlimited look-back in most states. If you were never registered and never filed, the state’s statute of limitations clock never started. In states like California, the non-filer look-back is capped at 8 years. In others, it’s genuinely open-ended.

There is also the question of what you owe vs. what Amazon already collected. Amazon collected and remitted sales tax on your Amazon transactions, but you weren’t registered in those states, so you didn’t file returns showing that collection. Some states will still expect filings, even retroactively, showing the transactions and the amounts Amazon handled.

The good news: Voluntary Disclosure Agreements (VDAs) exist specifically for this situation. A VDA lets you come forward proactively, pay back taxes and interest, get penalties waived entirely, and limit the look-back period to 3-4 years rather than indefinitely. They can often be filed anonymously before your identity is disclosed to the state. For an FBA seller with exposure across multiple states, working through VDAs in parallel is almost always the right path.

Learn more about how VDAs and registrations work.

If You Also Sell Outside Amazon, It Gets More Complex

If Amazon is your only channel, the compliance picture, while still requiring registration and return filing, is at least contained. Amazon is collecting the tax on your transactions. Your job is getting registered, filing the required returns (including zero-dollar ones), and managing non-sales-tax obligations like income tax.

If you also sell through your own website or another non-marketplace channel, the picture changes. Now you’re operating two compliance regimes simultaneously:

Amazon orders: Tax collected and remitted by Amazon, but registration and filing still your responsibility in nexus states.

Non-Amazon orders: Entirely your responsibility. Nexus monitoring, collection configuration, registration, and remittance. The physical nexus you established through FBA applies to your entire business, not just your Amazon channel. If you have nexus in Pennsylvania because Amazon stored inventory there, you’re responsible for collecting and remitting sales tax on your Shopify sales to Pennsylvania customers too.

This is the most common compliance gap among growing FBA sellers: Amazon is handling the Amazon side cleanly, while the Shopify store is quietly accumulating uncollected liability in the same states.

The Right Order of Operations

Pull Your FBA Inventory Ledger Report

Go back to when you first started selling. Map every fulfillment center to its state. That’s your nexus footprint.

Check Economic Nexus Too

Even in states where Amazon hasn’t stored your inventory, you may have crossed economic nexus thresholds through sales volume. Run your sales history through our nexus calculator to identify any additional exposure.

Quantify Historical Exposure

For states where you’ve had inventory but never registered, get an estimate of the liability, including penalties and interest, before deciding on next steps. You need to know the number before you can address it.

Evaluate VDA Eligibility

If historical exposure is material, VDAs are almost always the right path. They limit look-back, waive penalties, and give you a clean starting point. Critically, the window to file a VDA closes once a state contacts you directly. If you’ve already received a letter from a state, that changes the situation. Get advice before you respond.

Register in Your Current Nexus States

Going forward, you need to be registered in every state where Amazon is currently storing your inventory. Set a reminder to re-check your inventory report quarterly. Your nexus footprint changes as Amazon rebalances its network.

Audit Your Non-Amazon Channels

If you have a Shopify store or sell through any other channel, make sure you’re collecting correctly in every state where you have nexus. The FBA nexus that Amazon created applies to your whole business.

Amazon Did a Lot of the Work. You Still Have to Know What It Didn’t Do.

Amazon’s marketplace facilitator system genuinely simplified something that used to be very complicated. Most of your sales tax collection and remittance for Amazon orders is handled automatically. That’s real, and it matters.

But the inventory nexus problem doesn’t care about what Amazon collects. It cares about where your products are. And if you’ve been selling on FBA for more than a year without looking at your inventory ledger, you probably have nexus in states you’ve never thought about.

Here’s what we know from working with FBA sellers every day: the businesses that address this proactively almost always come out ahead. VDAs limit look-back periods. Penalties get waived. Registration gets you compliant going forward. The math works in your favor when you move first.

The businesses that wait for a state letter? They lose the VDA option. They face full look-back periods. And they pay penalties that could have been avoided entirely.

You now have the information you need to pull your inventory report, map your nexus footprint, and understand what obligations that creates. The question is what you do with it.

If you’re looking at a list of states and wondering where to start, or if you’ve already received correspondence from a state and aren’t sure how to respond, a conversation with someone who does this every day can save you significant time and money. Our What’s Next consultation is free, and it’s designed for exactly this situation. No pressure, no commitment. Just clarity on your specific nexus footprint and the best path forward for your business.

Most conversations about sales tax start with what you might owe. This one starts with what you might be owed.

Sales tax overpayment is more common than most finance teams realize. It happens when you pay more to the state than you were legally required to. It shows up in several ways:

• Misconfigured tax software
• Incorrect product taxability mappings
• Transactions that qualified for exemptions nobody claimed
• Purchases where vendors charged tax they had no right to charge

It builds quietly over months and years. It hides in returns that were filed without error and software that generated numbers without anyone verifying the results.

For many businesses, the discovery arrives as a surprise: a tax advisor runs a backward-looking review and finds six figures in recoverable overpayments sitting in two or three states. This money was already paid, and it can come back to you if you claim it before the statute of limitations (the deadline for filing a claim) closes.

That window is typically three years from the date the return was filed. The clock starts from when you paid, not from when you discover the error.

This article explains where overpayments hide, how to find them, and the exact process for getting your money back.

Paying Too Much Is Surprisingly Easy to Do

Sales tax compliance runs on a combination of software configuration, product classification, and human judgment. All three can fail. Unlike income tax, where overpayment often surfaces as a visible refund at filing time, sales tax overpayment tends to accumulate invisibly. Returns file cleanly. The software calculates something. Nobody checks whether what it calculated was right.

The businesses most likely to have recoverable overpayments share a few characteristics:

• They have been filing in multiple states for several years.
• They use automation software that was configured at implementation and has not been reviewed since.
• They have added new products or changed their product mix.
• They have been filing conservatively by taxing things as a default when the taxability was genuinely ambiguous.

Here is an important distinction: overpaying the state and over-collecting from customers are two different problems that often travel together. If you charged your customers more tax than required and remitted that full amount to the state, the path to recovery runs through the customer first. This article focuses primarily on overpayment on your own purchases (use tax) and on situations where you remitted more than was legally required. That’s the category most businesses never look at.

The Six Most Common Sources of Recoverable Overpayment

1. Incorrect Product Taxability Mapping

This is the most common source of overpayment, and often the largest. Your tax software or ERP has every product or service mapped to a tax code. If that mapping is wrong, every transaction for that product in every state has been calculating incorrectly. This happens when it was set up incorrectly at implementation or because the product changed without a corresponding code update.

If the error ran toward over-taxation, treating an exempt item as taxable, you’ve been overpaying. This is especially common for SaaS, digital goods, manufacturing inputs, and food items, all of which have state-specific exemptions that are frequently missed.

2. Paying Tax on Exempt Purchases

On the purchasing side, your company may have been paying sales tax to vendors on items that qualified for an exemption. Resale items, manufacturing equipment, raw materials that go directly into a final product, or items covered by an industry-specific exemption all fall into this category.

If your team didn’t provide valid exemption certificates to vendors, the vendor charged full tax. That tax is recoverable from the vendor, and if the vendor won’t refund it, in many states the buyer can file a claim directly with the state.

3. Filing in States Where Nexus No Longer Exists

Your business might have registered in a state and started filing returns. If you then closed a location, let a lease expire, or reduced sales below the economic nexus threshold but kept filing, you may have been remitting in states where you no longer had an obligation.

Overpaying in a state you should have deregistered from is recoverable, but only for the periods within the statute of limitations. Use our nexus calculator to check your current obligations against where you’re actually filing.

4. Double Remittance on Marketplace Sales

Multichannel sellers are particularly vulnerable here. Your business might sell on Amazon, where Amazon collects and remits as a marketplace facilitator. If you also file your own returns in those same states and include those Amazon-facilitated transactions in your reported figures, you are paying the same tax twice.

Many sellers don’t realize their filing logic is double-counting marketplace sales until someone runs a reconciliation. If you’re selling through both direct channels and marketplaces, this is worth checking. Our e-commerce sales tax guide covers the marketplace facilitator rules in more detail.

5. Unredeemed Credits on Product Returns and Bad Debts

When a customer returns a product, the sales tax collected on that original sale is legally recoverable. But recovery isn’t automatic. You have to file for it, typically via an amended return for the original period.

The same applies to bad debts: if you remitted sales tax on a sale where the customer ultimately never paid and you wrote off the receivable, most states allow you to recover that tax. Both of these credits almost always go unclaimed because businesses don’t build the recovery process into their returns workflow.

6. Misconfigured Automation Software

If your Avalara, Vertex, or other sales tax automation tool was set up incorrectly (wrong tax codes, stale taxability logic, address sourcing errors), it has been calculating and remitting the wrong amounts on every transaction since go-live.

Depending on the nature of the error, those amounts may be too high. A configuration review that identifies overtaxation can also tell you exactly how much you can get back. Our Avalara misconfiguration article walks through the most common setup errors and how to identify them.

The Refund Statute of Limitations

Here’s the thing most finance teams don’t know: the right to claim a sales tax refund expires. Each state sets its own statute of limitations for refund claims, but the most common window is three years from the date the original return was filed or the tax was paid, whichever is later. Some states allow four years. A handful are shorter.

Translation: a misconfiguration that started five years ago creates recoverable overpayments for the most recent three or four years, and a permanent write-off for everything before that. Every quarter you wait to look is another quarter of potential refunds that ages out.

A few things to know:

The clock runs from payment, not discovery. Finding out today that you’ve been overpaying since 2021 doesn’t reset the window. Returns from 2021 that fall outside your state’s statute of limitations are gone regardless of when you discovered the error.

Some states distinguish between seller-initiated and buyer-initiated claims. In most states, the seller (the business that filed the return) is the party who must file the refund claim. Buyers who were overcharged by a vendor may need to go through the vendor to recover the tax, or in some states can file directly.

Interest may be owed to you. Many states are required to pay interest on overpayments that they hold beyond a certain period. The rate varies by state, but it means the longer the state has had your money, the more you may be entitled to recover.

If you suspect overpayment, the worst thing to do is wait to investigate.

Warning Signs That Warrant a Full Review

A full reverse audit (the systematic backward-looking analysis of your historical returns) is the gold standard for identifying and quantifying overpayments. But before engaging that process, there are a few signals worth checking:

Flat effective tax rate despite changing product mix or geography. If your effective sales tax rate as a percentage of revenue has barely moved over several years while your business has expanded into new states or new product categories, that’s a signal. A correctly configured system in a changing business produces some variation.

Tax charged uniformly across all products in all states. If your returns show the same taxability treatment for every product regardless of state, you’re almost certainly over-taxing in some jurisdictions. Product-level exemptions exist in virtually every state, and they vary significantly.

Returns in states where you no longer have a presence. Pull a list of the states you’re currently registered and filing in, and cross-reference it against where you actually have nexus today. If there are mismatches, that’s worth investigating.

Vendor invoices with tax charged on purchases that should be exempt. If your company regularly buys manufacturing inputs, resale inventory, or capital equipment and your accounts payable team never screens invoices for tax correctness, you’re probably paying tax you shouldn’t be.

No credit taken for product returns or customer refunds in your returns. If your business processes returns but your sales tax returns don’t reflect corresponding credits, you’re leaving money with the state that belongs to you.

The Refund Process: Step by Step

Step 1: Identify the Overpayment Source and Period

Before filing anything, you need to know what you overpaid, in which state, and for which periods. This is where a reverse audit or configuration review comes in. The goal is a clear, quantified analysis: “We over-remitted $X in State Y for periods Z through Z because of [specific error].” That analysis is the foundation of every refund claim.

Step 2: Determine Whether You Need to Refund Your Customers First

The overpayment might have resulted from over-charging customers by collecting more tax from them than was legally required and remitting it to the state. In this case, most states require you to refund or credit your customers before the state will issue a refund to you. This can significantly complicate claims involving large customer bases.

If the overpayment came from your own purchasing activity (use tax) or from a taxability error on your sales that you didn’t actually collect from customers, this step may not apply.

Step 3: File Amended Returns for Affected Periods

In most states, refund claims for prior-period overpayments are made by filing amended returns for the specific periods in question. These amended returns show the corrected tax liability alongside the original, with supporting documentation explaining the basis for the change.

Some states also accept a separate refund claim form rather than amended returns. The process varies by state.

Step 4: Prepare Documentation

State tax authorities don’t take overpayment claims on faith. You’ll typically need to provide:

• Amended returns for each affected period
• Exemption certificates or other documentation supporting the claimed exemptions
• Invoices and transaction records supporting the calculation
• Sometimes a written explanation of the error and the basis for the refund

Step 5: File Within the Statute of Limitations

This step is not optional and not flexible. The refund claim must be filed before the applicable statute of limitations expires for each period. For a claim covering multiple years, some periods may already be expired by the time you start.

Filing a “protective claim” for periods approaching expiration can preserve your rights while the analysis continues. A protective claim is essentially a placeholder filing that keeps your options open before you have fully quantified the amount.

Step 6: Follow Up

State refund processing times vary enormously, from a few weeks to more than a year for complex claims. Some states audit refund claims the same way they audit liabilities. Being prepared to respond to follow-up inquiries with documentation is part of the process.

When the Numbers Are Big Enough, Recovery Pays for Itself

For businesses that suspect material overpayment across multiple states or periods, a professional overpayment recovery review is almost always worth the investment. The math tends to work out. In our experience, a recovery that identifies six figures in refundable overpayments across a few states returns the cost of the review many times over. This work is typically done on a contingency basis (where the advisor takes a percentage of the recovered funds) or a fixed-fee basis (where you pay a set price), which aligns the advisor’s incentives with the outcome.

What a professional recovery review covers:

• A systematic analysis of your historical returns, transaction data, and taxability configuration
• Identification of overpayment sources and their dollar value by state and period
• Determination of which periods fall within the refund statute of limitations
• Preparation and filing of the amended returns or refund claims needed to recover the money

This is what our overpayment recovery service is built for. Not an audit defense engagement, not a compliance setup, but a backward-looking exercise focused entirely on getting recoverable money back before the window closes.

Claim Your Money Before Time Runs Out

Sales tax overpayment doesn’t announce itself. It accumulates quietly across hundreds or thousands of transactions, buried in clean filings and automated systems that ran without human oversight. Most businesses that find recoverable overpayments had no idea they existed until someone looked.

The statute of limitations doesn’t care when you discover the error. It cares when you file. Every quarter you wait is another quarter of potential refunds that ages out permanently.

If there’s any chance your business has been over-remitting (because of a taxability mapping error, an exempt purchase that got taxed, a misconfigured system, or any other reason), the right time to look is now. Not next quarter. Not after your next audit. Now.

The process is straightforward:

• Identify the overpayment source and period
• Quantify the dollar amount by state
• File the amended returns or refund claims within the statute of limitations
• Follow up until the check arrives

For businesses with material overpayments across multiple states, a professional recovery review typically pays for itself many times over.

This isn’t a compliance problem you need to fix. This is money that already belongs to you, sitting in state accounts, waiting to be claimed.

Getting mail from the department of revenue usually causes a knot in your stomach. Something landed in your inbox or mailbox from a state tax authority. It has words like “nexus questionnaire,” “tax filing determination” or “business activity survey” across the top. There may be a deadline. It probably asks a series of yes/no questions about your business operations in that state.

If you’re not sure what it is or whether to respond, stop. Do not fill it out yet.

This article explains exactly what a nexus questionnaire is, why states send them, what your response (or non-response) actually means and the single most important thing to do before you begin filling out the form. Because the way you respond, or don’t respond, can determine whether you end up in an audit or qualify for a program that limits your liability significantly.

What You’re Actually Looking At

Think of a nexus questionnaire as a state’s way of asking if you belong in their tax system. The department of revenue wants to know if your business connection to their state is strong enough that you should be collecting and paying sales tax there.

When looking at your business, states care about two main triggers:

Physical nexus includes offices, employees, warehouses, equipment, inventory, contractors or even a sales rep passing through the state regularly.

Economic nexus means crossing a revenue or transaction threshold in that state, even with no physical presence at all. In 2018, the Supreme Court ruled in South Dakota v. Wayfair that states can tax businesses based purely on sales volume. This created economic nexus. Now, most states draw the line at $100,000 in sales or 200 transactions per year.

If the state concludes you have nexus, you’ll be required to register, file returns and potentially address any prior periods where you should have been collecting but weren’t.

Why Did You Get One?

States send these to businesses they suspect may have a tax obligation they’re not meeting. Their data sources include third-party information returns, marketplace and platform data, business license filings in other states, trade publication subscriber lists and inter-agency data sharing.

Take a deep breath. Getting one doesn’t mean you’ve been found guilty of anything. It means the state thinks you might owe something, and they’re asking you to confirm or deny.

Why This Isn’t Just Paperwork

A nexus questionnaire feels like a form. It’s not just a form. It is the first step in a process that could lead in several different directions depending on how you respond, and some of those directions are significantly better than others.

Three things make this high-stakes:

1. Your answers create a legal record.

Once you submit a signed questionnaire, those responses are on record with the state. If you answered “yes” to something that wasn’t quite accurate, or “no” to something that was actually a “yes, except for…” situation, it is very hard to change your answers later. The questions are almost always yes/no, which means your specific business circumstances often don’t fit cleanly into the format. An unqualified “yes” can confirm nexus that may not actually exist in the way the state assumes.

2. Ignoring it is not a safe option.

Not responding doesn’t make the questionnaire go away. Most states will take non-response as confirmation that you have nexus, issue an assessment on their own estimate of your liability and open an audit. You then have to fight that assessment, which is expensive, time-consuming and far less favorable than if you’d engaged proactively.

3. How you respond affects your VDA eligibility.

This is the piece most businesses miss. Most states offer a Voluntary Disclosure Agreement (VDA) program. This lets you come forward voluntarily. You pay back taxes and interest. In return, the state waives penalties and limits the look-back period to three or four years. It’s one of the most valuable tools available to businesses with sales tax exposure.

Here’s the critical nuance. Think of a VDA like turning yourself in for a speeding ticket to get a lighter fine. It only works if the police haven’t already pulled you over. In the tax world, a nexus questionnaire is a form of contact. Some states consider this questionnaire a simple warning. Other states view it as the flashing police lights. The line varies by state, and it matters enormously.

If you respond to the questionnaire in a way that triggers an audit opening, your VDA window may close simultaneously.

Before You Do Anything Else

The Option You Might Still Have (But Only If You Move Fast)

You might have sales tax exposure in the state that sent this questionnaire. You might also have exposure in other unregistered states. A VDA is often your best path to resolving the situation. It helps you avoid heavy penalties and an open-ended audit look-back.

Here’s how VDAs work in this context:

• You (or a representative, often anonymously) approach the state and disclose your intention to come into compliance
• The state limits the look-back period, typically to 3 to 4 years rather than potentially unlimited for non-filers
• Penalties are typically waived entirely (penalties can represent 25 to 50 percent of the total tax owed)
• Once a VDA is finalized, those disclosed periods are generally closed to further audit

The Timing Issue

Most states disqualify businesses from VDA programs once the state has made direct contact regarding a specific liability. A general nexus questionnaire may or may not count as that contact, depending on the state. Some states draw a clear distinction between informational questionnaires and audit notices. Others treat any questionnaire response as closing the VDA window.

This is why the first call you make when you get a nexus questionnaire should be to a sales tax specialist, not your general accountant. The question isn’t just “do I owe money?” It’s “do I still have options, and which of them is most favorable given the exact situation I’m in right now?”

The rules vary significantly from state to state. In some states, responding to a questionnaire can trigger a closer review of prior periods, while in others your VDA window may remain open. Knowing these specific state rules can save your business tens of thousands of dollars.

Your Next Steps, In Order

Step 1: Don’t Respond Yet

Put the questionnaire somewhere safe. Note the deadline. You have time to do this right.

Step 2: Identify the State and the Tax Type

The questionnaire should specify which tax it’s addressing: sales and use tax, income/franchise tax or both. The implications differ. This article focuses on sales tax, which is the most common trigger.

Step 3: Assess Whether You Actually Have Nexus in That State

Do you have employees, contractors, property, inventory or regular in-state activity there? Have you crossed $100,000 in sales or 200 transactions in that state? Our nexus calculator can give you a starting read. But a questionnaire situation warrants a professional analysis, not just a calculator.

Step 4: Contact a Sales Tax Professional Before You Respond

This is not optional if there’s any chance you have historical exposure. You need someone who can evaluate your actual nexus position, tell you whether VDA eligibility is still intact in this state and help you respond in a way that accurately reflects your situation without inadvertently creating a worse one.

Step 5: Respond Truthfully, Carefully and With Context

Once you’ve had professional guidance, respond. Truthful answers are required. There’s no benefit to misrepresenting your activities, and misrepresentation creates far greater problems than whatever the underlying tax issue is. But “truthful” and “accurate” are not the same as “unqualified yes/no.” A good advisor will help you provide context where the form doesn’t accommodate your specific circumstances, sometimes through a supplemental letter alongside the required form.

Step 6: Understand What Comes Next

After the state receives your response, they’ll either determine you don’t have nexus (case closed), determine you do and require registration going forward or open a broader review of prior periods. What happens next depends heavily on how you answered and what your actual exposure looks like. Getting ahead of that analysis now, before the state drives the process, is always the better position.

One Questionnaire Is Often a Sign of a Bigger Picture

The fact that one state found you doesn’t mean the others won’t. States increasingly share data with each other. If your business has crossed economic nexus thresholds in multiple states without registering, this questionnaire may be the first of several.

This is also the moment to do a full nexus study: a complete analysis of where your business actually has obligations vs. where you’re actually filing. Most businesses that receive their first nexus questionnaire discover, upon review, that they have similar exposure in 3 to 10 other states they hadn’t accounted for. Addressing all of it proactively, through VDAs where eligible, is dramatically more cost-effective than addressing each state as it finds you.

If you’re navigating a merger or acquisition, this becomes even more critical. Buyers often inherit the seller’s sales tax liabilities, and a nexus questionnaire received during due diligence can significantly impact deal terms. Understanding your full exposure before closing protects both parties.

You Have More Options Than You Think, But Only Right Now

Getting a nexus questionnaire doesn’t mean you are in an audit. It means you face a decision. The most successful businesses pause and get the right advice first. They understand all their options before the state takes those options away.

Here’s what we know from working with businesses in exactly this situation across all 45 sales tax states: the window between receiving a questionnaire and losing your best options is narrow. VDA eligibility, penalty waivers, limited look-back periods. These aren’t theoretical benefits. For a business with even modest sales tax exposure, the difference between proactive resolution and reactive compliance can easily reach tens of thousands of dollars.

The questionnaire in front of you is asking simple yes/no questions. But the right answer for your business depends on factors that form can’t capture: your actual nexus footprint, your historical exposure, your VDA eligibility in this state and others and the specific way this state treats questionnaire responses vs. audit notices.

That’s not information you should guess at. And it’s not something a general accountant or bookkeeper is equipped to evaluate. State revenue departments update their contact rules, threshold definitions and VDA disqualifiers constantly.

The Sales Tax People work with businesses exactly at this stage to help you understand your options before submitting a response. A consultation gives you clarity on your current standing and your best path forward.

Will you let a generic form dictate your company’s financial future, or will you take control of the narrative before the state does?

The investment banker is engaged. The CIM is drafted. You’re weeks away from fielding LOIs for the company you’ve spent years building. And at some point in the next few months, a buyer’s tax team will pull your sales tax records, run a nexus analysis, and produce a number.

The question isn’t whether they’ll find something. It’s whether you already know what they’ll find, and whether you’ve had any time to do something about it.

Sellers who wait for buyer diligence to surface sales tax problems lose control of the narrative entirely. They end up reacting to someone else’s exposure estimate, negotiating from a weakened position, and frequently absorbing a purchase price reduction or escrow holdback that could have been avoided. Or at least minimized.

This article walks through exactly what buyers look for in your sales tax records, what the financial stakes are when they find issues, and what your options are if you start early enough to actually do something about it.

The Buyer’s Tax Team Has a Checklist. Here’s What’s On It.

Before you can prepare for diligence, you need to understand what’s coming. A buyer’s sales tax review isn’t a casual glance at your returns. It’s a systematic, adversarial examination by people whose job is to find problems and use them in negotiation.

Here’s what their checklist typically includes:

Nexus footprint vs. registration list. Buyers will map where your company actually has nexus against where you’re registered and filing. This means analyzing both physical presence (offices, employees, warehouses, inventory) and economic nexus based on revenue thresholds by state. Any gap between where you should be filing and where you are filing gets treated as unquantified exposure.

Return history and filing completeness. Are returns filed on time in every registered state? Any gaps, amended returns, or delinquent periods get flagged immediately. A pattern of late filings or missing periods signals broader compliance issues.

Taxability treatment. Are the right products and services being taxed correctly? This is especially scrutinized for SaaS and software companies (more than two dozen states tax SaaS in some form as of 2026), digital goods, services, and mixed-transaction businesses. Incorrect taxability treatment that’s been running for years creates cumulative exposure that compounds quickly.

Exemption certificate files. Buyers will ask for documentation proving that exempt sales were actually exempt. Missing, expired, or incomplete certificates on file are one of the most common audit triggers found during diligence. If you can’t prove an exemption was valid, the buyer assumes it wasn’t.

Audit history and open state notices. Any outstanding notices, open audits, or assessments survive the deal and become the buyer’s problem. They will price accordingly, often conservatively.

Use tax compliance. This one is often overlooked by sellers but never by buyers’ tax teams. If your company hasn’t been self-assessing use tax on taxable purchases, that’s a separate exposure line that gets added to the total.

Here’s the key point: buyers’ estimates of exposure are deliberately conservative. They’re not trying to get to the right number. They’re trying to protect themselves from worst-case scenarios. If you haven’t done your own analysis, you’ll be responding to their number, not presenting yours.

What “We Found an Issue” Actually Costs You

When a buyer’s diligence team surfaces material sales tax exposure, the deal doesn’t necessarily die. But it shifts. And the shift almost always favors the buyer.

Here are the typical outcomes, in rough order of how painful they are for the seller:

The common thread across all of these outcomes is that the seller is reacting. Every one of these scenarios involves the buyer having the information while the seller catches up. That’s a structurally weak negotiating position.

And it was avoidable.

We recently worked with a seller who identified and resolved over $500,000 in exposure before it hit the closing table. The difference wasn’t luck. It was timing. They looked at their records before a buyer did, quantified the issue on their own terms, and presented a clean resolution rather than scrambling to respond to someone else’s estimate.

Why “We File in Our Home State” Isn’t the Answer Anymore

The most common misconception we see from sellers: filing in the states where you have offices or warehouses equals compliance.

That hasn’t been true since 2018.

What changed: The Supreme Court’s South Dakota v. Wayfair decision established economic nexus. Now, selling into a state above certain revenue thresholds (typically $100,000 in sales or 200 transactions per year) creates an obligation to collect and remit sales tax, even with zero physical presence in that state.

What this means for growing companies: Most businesses that scaled over the past several years crossed economic nexus thresholds in multiple states without ever formalizing compliance in those states. The company files where it has offices. The exposure is where it has customers.

Why the math matters: Unlike income tax, sales tax is a gross revenue tax. It can’t be offset by operating losses. A company generating $15 million in revenue with a 6% average rate across states where it hasn’t been filing is looking at significant potential exposure, regardless of whether the company is profitable.

Who’s at elevated risk: Sellers who grew fast, expanded into new markets, changed their product mix (especially toward digital or SaaS), or went through any prior change of ownership are at particularly elevated risk. Each of those transitions likely triggered new nexus obligations that may not have been addressed.

The timing reality: sellers who start this analysis 6-12 months before going to market have meaningful options. Sellers who start after the LOI is signed are mostly managing damage.

If you’re curious what buyers will see when they look at your records, that’s exactly what a sell-side diligence engagement is designed to answer.

The Earlier You Look, the More Options You Have

Timing is the entire variable that separates a seller who controls the narrative from one who doesn’t. Here’s what’s possible at different stages.

If You’re 6-12 Months Out from Market

Full runway. You can:

• Commission a nexus study to map your actual exposure footprint across all states
• Quantify prior-period liability with penalties and interest included so you know the real number before anyone else does
• File Voluntary Disclosure Agreements (VDAs) proactively in states with meaningful exposure

A quick note on VDAs: this is a program offered by most states that lets companies voluntarily come forward, pay what they owe, and get penalties waived in exchange. Penalties can run 25-50% of base tax owed, so this isn’t a small benefit. VDAs also typically limit the look-back period to 3-4 years rather than indefinitely. And critically, VDAs can often be initiated anonymously, meaning you explore the terms before disclosing the company’s identity.

Learn more about how VDAs work on our registrations and VDAs page.

You can also use this window to:

• Get your exemption certificate files in order
• Build a clean compliance track record in the months before diligence begins
• Document everything so buyers see the work you’ve done

If You’re Already in Process (LOI Signed or Imminent)

The window is tighter but options still exist:

• A rapid-turnaround nexus and exposure analysis at least gives you your own number before the buyer presents theirs
• VDAs can still be negotiated as part of deal terms, with seller and buyer agreeing on who funds the liability and how the process unfolds post-close
• You can negotiate from a position of awareness: “We’re aware of this, here’s our quantification, here’s our remediation plan” is a fundamentally different conversation than simply reacting to the buyer’s estimate

Here’s the contrast to keep in mind: a VDA before going to market means you controlled the process, limited the look-back, eliminated penalties, and presented a clean resolution to buyers. A VDA forced by buyer diligence means the buyer typically controls the process, sets the escrow amount, and you fund a liability that may have been smaller if you’d caught it first.

Sell-Side Sales Tax Checklist: What to Review Before You Go to Market

Whether you’re 12 months out or already fielding interest, here’s what to review.

12+ Months Before Market

• Run a nexus analysis: where do you have economic or physical nexus vs. where are you registered?
• Pull your full state registration list and filing history and look for gaps
• Audit your taxability setup: are all product and service lines treated correctly by state?
• Review exemption certificate files for completeness and currency
• Assess use tax compliance on your own taxable purchases

6-12 Months Before Market

• Quantify prior-period exposure in unregistered states, including penalties and interest
• Evaluate VDA eligibility in all states with meaningful exposure
• File VDAs anonymously where appropriate to limit look-back and eliminate penalties
• Remediate any exemption certificate gaps
• Establish clean, forward-going compliance in all newly registered states
• Document everything. Buyers will want to see the work.

At or After LOI

• Commission a rapid exposure analysis if not already done. You need your own number.
• Negotiate VDA rights and seller/buyer funding split into purchase agreement terms
• Ensure all open state notices and audits are disclosed and accounted for in deal terms
• Review indemnification survival periods for sales tax reps. Know what you’re agreeing to.
• Work with a sales tax specialist, not just your general M&A counsel, on the SALT provisions

You Built Something Worth Selling. Don’t Let Sales Tax Erode What You Walk Away With.

Sales tax exposure is one of the few deal risks that is genuinely fixable given enough runway. The sellers who protect their valuation are the ones who looked at their records before a buyer did. They knew their number. They cleaned up what they could. And when diligence started, they weren’t surprised.

The difference between a seller who negotiates from strength and one who scrambles to respond comes down to timing and preparation. A clean sales tax record heading into a transaction isn’t luck. It’s the result of understanding what buyers will look for, quantifying exposure on your own terms, and taking action while you still have options.

If you’re 6 to 24 months from a potential sale, that’s the right window. Starting now means you can control the process, limit your look-back periods, eliminate penalties through VDAs, and present a clean compliance story to buyers. Waiting means you’ll be reacting to someone else’s estimate with someone else’s timeline.

The LOI is signed. The quality of earnings report is underway. Your deal team is deep in financial diligence, reviewing customer concentration, working capital adjustments, and EBITDA normalization. And nobody has said the words “sales tax” yet.

That’s the problem.

Sales tax is one of the most common material liabilities uncovered during M&A diligence. It’s also one of the most consistently overlooked until it’s too late to address cleanly. Unlike income tax, sales tax exposure rarely shows up on a balance sheet. It hides in unregistered states, unfiled returns, and years of mistreated taxability for SaaS, digital goods, or services that crossed state lines without anyone asking the compliance question.

Buyers often set aside 2 to 12 percent of purchase price for potential tax liabilities. Sales tax exposure alone can represent up to 10 percent of a target company’s revenue when penalties and interest are factored in. That’s not a rounding error. That’s a material number that changes deal economics.

This article explains exactly how sales tax liability works in a transaction, what to look for during diligence, and what your options are before and after close. Whether you’re evaluating an asset purchase or stepping into a stock deal, you’ll walk away knowing where the risks live and how to address them before they become your problem.

Sales Tax Is the Liability Nobody Sees Coming

Here’s what makes sales tax different from almost every other liability on your diligence checklist: it’s self-assessed and self-reported. If a company never registered in a state, there’s no notice, no filing history, and no line item on the balance sheet. The liability is invisible until someone goes looking.

And when someone does go looking, the numbers can be significant.

Private companies are especially prone to hidden exposure. Growth-stage businesses tend to prioritize revenue over compliance infrastructure. That’s not negligent. It’s a rational business decision when you’re trying to hit milestones and close funding rounds. But it means that by the time a company becomes an acquisition target, there may be years of unaddressed nexus obligations sitting quietly in the background.

The 2018 South Dakota v. Wayfair decision made this worse. Before Wayfair, companies generally only had sales tax obligations in states where they had a physical presence. After Wayfair, any company selling across state lines likely has economic nexus obligations in multiple states based purely on sales volume or transaction count. A SaaS company with customers in 30 states may have nexus in 20 or more of them, even if every employee works from a single office.

The exposure isn’t just the uncollected tax. It’s tax plus penalties plus interest. Depending on the state and how long the liability has been accruing, penalties and interest can add 25 to 50 percent on top of the base tax owed. A $500,000 exposure becomes $750,000 fast.

Certain industries carry higher risk than others:

• SaaS and software companies: As of 2026, 24-25 states tax SaaS in some form. The rules vary wildly. Some states tax it as tangible personal property, others as a service, and some don’t tax it at all. Companies that assumed “software isn’t taxable” often have multi-state exposure they’ve never addressed.
• E-commerce businesses: High transaction volumes across many states create economic nexus quickly. Marketplace facilitator laws have shifted some liability, but not all of it.
• Services companies that expanded multi-state: Professional services, consulting, and B2B services have complex taxability rules that differ by state. A company that started in one state and grew nationally may have never reassessed its obligations.
• Companies that changed ownership or product mix: Any business that pivoted, added product lines, or went through a prior transaction may have taxability configurations that no longer match what they actually sell.

When acquirers’ advisors start pulling data, these gaps surface quickly. The question isn’t whether there’s exposure. The question is how much, and who’s going to pay for it.

How You Structure the Deal Determines Who Inherits the Problem

The single most consequential sales tax decision in an M&A transaction often happens before diligence even begins: how is the deal structured?

Asset purchase versus stock purchase determines not just the tax treatment of the transaction itself, but how much historical sales tax liability the buyer is exposed to. Get this wrong, and you may be inheriting years of someone else’s compliance failures.

Even an asset purchase doesn’t fully insulate a buyer. Many states have statutory successor liability provisions that impose liability regardless of deal structure, particularly when bulk sale clearance certificates are not obtained.

New York is a good example. The state explicitly warns buyers not to pay the seller until confirming there are no outstanding tax obligations. If you skip the clearance certificate and the seller had unpaid sales tax, you’re on the hook. California, Illinois, and several other states have similar provisions.

Successor liability (the legal principle that makes a buyer responsible for a seller’s obligations) can attach in asset deals when:

• Bulk sale notification requirements aren’t followed
• The buyer continues the seller’s business without meaningful change
• Courts find a “de facto merger” based on continuity of operations, management, or ownership
• The transaction is structured to avoid creditors

The takeaway: deal structure matters, but it’s not a complete shield. You still need to know what you’re buying.

What Good Diligence Covers (And What Most Teams Skip)

Most deal teams outsource tax diligence to generalist advisors who know income tax well but may not go deep on state and local tax. Sales tax gets a cursory review, if it gets reviewed at all. That’s how material liabilities slip through.

A proper sales tax diligence review examines six areas:

Nexus footprint: Where does the target have economic or physical nexus? Where are they registered versus where they should be registered? The gap between those two lists is your exposure. You can use a nexus calculator to get a preliminary read, but a full nexus study requires transaction-level data analysis.

Return history: Are returns filed in all registered states? Any gaps, amended returns, or notices outstanding? A company that’s registered but hasn’t filed in 18 months has a different problem than a company that never registered at all.

Taxability analysis: Are the right products and services being taxed? This is especially critical for mixed transactions, SaaS, digital goods, or professional services. A company might be collecting tax on some products but not others, or applying the wrong rate, or treating bundled offerings incorrectly. Taxability errors create both over-collection risk (customer refund liability) and under-collection risk (state liability).

Exemption certificates: Does the company have valid, current exemption documentation on file for exempt sales? Missing certificates are one of the most common audit triggers. If 30 percent of a company’s sales are marked as exempt but only half have documentation, that’s a quantifiable exposure.

Audit history: Any open audits, state notices, or assessments? These survive a deal. If the target is in the middle of a California audit, that audit continues after close regardless of deal structure.

Use tax compliance: Many companies are diligent on sales tax but ignore use tax on their own purchases. Use tax applies when a company buys goods or services without paying sales tax and owes the tax directly to the state. Auditors always check both sides.

The output of this review is a quantified exposure estimate. Not a vague “there might be risk” statement, but an actual number the deal team can work with when structuring indemnifications, escrow, or purchase price adjustments.

We’ve worked on transactions where this review identified over $500,000 in exposure that wasn’t on anyone’s radar. That’s not unusual. It’s what happens when you actually look.

Once You Find the Exposure, Here’s What You Can Actually Do About It

Finding sales tax exposure before a deal closes is infinitely better than finding it after. Before close, you have leverage. You have options. You can negotiate who absorbs the liability and how. After close, it’s your problem.

Here’s the menu of options.

Price Adjustment and Indemnification

The most common path. Buyer and seller negotiate who absorbs the liability, typically via an indemnification clause in the purchase agreement with escrow funds held for a defined period.

A common escrow structure is 135 percent of estimated exposure, held for 18 to 24 months. The cushion accounts for uncertainty in the estimate and gives time for VDA resolutions or audits to play out.

Indemnification language matters. You want clear definitions of what constitutes a pre-close liability, how claims are made, and what happens if the escrow runs out before all liabilities are resolved.

Voluntary Disclosure Agreements (VDAs)

A VDA allows a company to come forward voluntarily in each state with exposure, pay back taxes and interest, and in most cases get penalties fully waived and the look-back period limited to three to four years (versus potentially unlimited for non-filers).

VDAs can often be negotiated anonymously before the company’s identity is disclosed. This matters because once a state knows who you are, you lose the ability to control timing.

Informed buyers often negotiate the right to file VDAs post-close with the seller funding the pre-close portion of the liability. This gives the buyer control over the process while allocating costs appropriately.

VDAs are one of the most effective tools for cleaning up historical exposure. If you’re evaluating a target with multi-state nexus issues, this is likely part of your remediation plan. Learn more about how registrations and VDAs work in practice.

Bulk Sale Clearance Certificates

In states that require them, getting a clearance certificate from the tax authority before transferring assets confirms the seller has no outstanding tax obligations. Skipping this step can make the buyer liable for the seller’s unpaid taxes.

The process takes time. Some states respond in days, others take weeks. Build this into your closing timeline.

Tax Escrow

Funds held in escrow post-close to cover liability that gets confirmed through VDA resolution or audit. This is standard in PE-backed deals where the exposure is material but not fully quantified.

The escrow amount, release conditions, and duration should all be negotiated based on the specific exposure identified during diligence.

Post-Close Integration Priorities (First 90 to 100 Days)

Once the deal closes, the clock starts on integration. Sales tax shouldn’t be an afterthought.

Re-register the acquired entity in all required jurisdictions under the new ownership. State requirements vary on whether this is a simple update or a new registration.

Consolidate exemption certificate systems and validate that existing certificates are current. Acquired companies often have certificates scattered across email folders, filing cabinets, and outdated systems.

Audit the acquired company’s taxability setup in its ERP or billing system. This is a common place where miscoding survives an acquisition. If the system is configured to not charge tax on a product that should be taxed, that error will continue generating liability until someone fixes it.

Assess combined entity nexus. The buyer’s existing operations may now create additional nexus for the acquired entity, and vice versa. A buyer with employees in 15 states may create physical nexus for an acquired company that previously only had economic nexus in five.

File any agreed-upon VDAs if they were negotiated as a pre-close condition.

For a broader view of compliance fundamentals, especially if the target is an earlier-stage company, our sales tax checklist for startups covers the baseline requirements that should already be in place.

Sales Tax M&A Checklist: What to Cover Before You Close

This checklist covers the essential steps at each phase of a transaction. Use it as a reference for your deal team.

Pre-LOI and Early Diligence

• Request the target’s state registration list and compare to states where they have nexus
• Ask for the last three years of sales tax returns by state
• Flag any states where the target sells but is not registered
• Identify the deal structure (asset vs. stock) and its successor liability implications

During Diligence

• Commission a full nexus study for the target entity
• Review exemption certificate files for completeness and currency
• Pull audit history and any outstanding state notices or assessments
• Assess taxability treatment for all product and service lines, especially digital, SaaS, or services
• Quantify prior-period exposure with penalties and interest included
• Identify bulk sale notification requirements in applicable states

Pre-Close

• Negotiate indemnification language in the purchase agreement for pre-close liabilities
• Determine whether VDAs should be filed pre-close or negotiated as a post-close right
• Obtain bulk sale clearance certificates where required
• Establish escrow structure if exposure is material

Post-Close (First 90 to 100 Days)

• Re-register or transfer tax accounts in all required jurisdictions
• Integrate acquired entity into buyer’s compliance calendar and filing process
• Validate and update taxability configuration in billing and ERP systems
• File any agreed VDAs
• Assess combined entity nexus footprint, as new obligations may exist that didn’t before the deal

The Best Time to Deal With Sales Tax Is Before the Deal Is Done

Most deals where sales tax becomes a problem aren’t the result of negligence. Sales tax compliance is genuinely complex, self-assessed, and easy to deprioritize during a growth phase. When you’re focused on hitting revenue targets and building a business, nexus analysis doesn’t make the weekly priority list. The issue is that M&A is the moment all of that catches up.

A specialized sales tax review during diligence doesn’t add complexity to the deal. It removes it. You go into negotiations knowing the actual number, with a plan to address it, rather than discovering exposure at a closing table or, worse, in an audit 18 months post-close when the seller is long gone and the escrow has been released.

The math is straightforward. A thorough diligence review costs a fraction of what unidentified exposure costs when it surfaces later. We’ve worked on deals ranging from founder exits to large strategic acquisitions, including transactions like the $1.65 billion Acima acquisition by Rent-A-Center, where identifying and resolving sales tax exposure early kept it from becoming a deal issue or a post-close liability.

If you’re in or approaching a transaction, the due diligence review starts with a conversation. No fees, no pressure. Just a clear picture of where you stand and what your options are.

For decades, software sold over the internet lived in a gray area of sales tax law. States wrote their tax codes when “tangible personal property” meant something you could hold in your hands. Software didn’t fit neatly into that world, so most states either exempted it, taxed it inconsistently, or just looked the other way.

California just changed the rules.

Senate Bill 122, passed by the California Legislature on June 18, 2026, and now awaiting Governor Newsom’s signature, would redefine “tangible personal property” to include digital products, specifically prewritten computer software. That includes software you download. Software you access through a browser. SaaS platforms your team logs into every day. If signed, those purchases would be subject to California sales and use tax starting January 1, 2027.

The bill has broad support across the legislature and is described as part of a three-party consensus agreement among the Assembly, Senate, and Governor. Signature is widely expected. But until it happens, this remains a proposal, not a mandate.

That said: the January 2027 effective date leaves almost no runway. If you wait for the governor’s signature before you start preparing, you will already be behind. Here’s what the bill does and what you should be doing now.

What Changed, Exactly

California’s Sales and Use Tax Law has always taxed “tangible personal property,” meaning things you can see, touch, weigh, or measure. SB 122 would add a second category to that definition: digital products and any copyright or patent interests associated with them.

A “digital product” under the new law means prewritten computer software. That covers three delivery methods:

• Transferred on tangible storage media: software on a disc or USB drive (already taxable in most cases, now codified)
• Transferred electronically: software you download directly
• Accessed remotely: software that runs on the vendor’s server and you access via password or digital code (what most people call SaaS or cloud software)

The law is specific that this applies to prewritten software, meaning software that exists for general or repeated sale. Custom software built specifically for your company is still excluded.

What’s Not Included

The bill carves out several categories from the “digital product” definition. These would be exempt from the new tax:

• Digital audio works: music, podcasts, ringtones
• Digital audiovisual works: streaming video, films
• Digital books: ebooks and the like
• Digital video games: consumer gaming products
• Digital visual works: digital artwork
• Digital assets: cryptocurrency and similar blockchain-based instruments
• Digital infrastructure: cloud services where you run your own software on someone else’s platform

That last carve-out deserves attention. “Digital infrastructure” means cloud-based services where the customer creates, deploys, scales, or runs their own software on the provider’s platform, without managing the underlying hardware or network. Think AWS, Google Cloud, Microsoft Azure. Those are explicitly excluded.

The line being drawn here is between using someone else’s software (taxable) and running your own software on someone else’s infrastructure (not taxable). If your business relies heavily on IaaS or PaaS providers, those costs are outside the scope of this law. If your team logs into a vendor’s SaaS platform to do work, those subscriptions are now in scope.

The $5 Million Threshold: A Major Compliance Wrinkle for Enterprise Buyers

Here’s where it gets operationally complicated for mid-market and larger companies.

The bill includes a threshold provision: if a purchaser buys more than $5 million in taxable digital products from a single retailer in a calendar year, the retailer would be relieved of the obligation to collect and remit the tax. The purchaser would become responsible for self-assessing and paying use tax directly to the California Department of Tax and Fee Administration (CDTFA).

That $5 million figure is per retailer, per year. It is not a combined total across all your software vendors. It is vendor-by-vendor. And starting January 1, 2028, it applies if you exceeded the threshold in either the current or the preceding calendar year.

If this threshold applies to you, you will need to obtain a use tax direct payment permit from the CDTFA. That permit requires you to register the California business locations where you expect to first use the software, and to file and pay use tax returns directly. This is not a passive process. It creates active compliance obligations that many finance teams are not currently set up to handle.

For most mid-market companies, the $5 million threshold won’t apply to any single software vendor. But if you have large enterprise agreements covering a major ERP platform, a sprawling CRM, or a mission-critical cloud suite, it’s worth doing the math now, before 2027 arrives.

Sourcing Rules: Where Does the Sale Happen?

SB 122 would establish clear rules for determining where a digital product sale is sourced, which matters for figuring out what local sales tax rate applies.

For software that isn’t sold in person at a physical location, the sourcing hierarchy works like this:

1. Purchaser’s billing address
2. Purchaser’s shipping or delivery address
3. Mailing address associated with the purchaser’s payment instrument
4. Purchaser’s mailing address

The bill also includes a presumption worth knowing: if you purchase a digital product from outside California and use it in California within 90 days of purchase, it’s presumed the purchase was made for use in California. Use tax applies, regardless of where the transaction technically occurred.

This is the state closing a gap. Companies that historically purchased software from out-of-state vendors and didn’t pay California sales tax will now have a clear, codified obligation to self-report and pay use tax on those purchases.

What This Means If You Sell Software

If SB 122 is signed and your company sells prewritten software to California customers, whether via download or SaaS subscription, you would have new collection obligations starting January 1, 2027.

If your California customer buys less than $5 million from you annually, you collect and remit just like you would for any other taxable product. The sourcing rules are clear, and the CDTFA is receiving $750,000 in funding specifically to build out the administrative infrastructure for this.

The more complex situation involves multi-state licensing. If you sell a software license that covers users in multiple states simultaneously, California’s law allows for an apportionment methodology. The CDTFA is authorized to set rules for how to calculate the tax due on licenses with concurrent multi-location use. Those rules don’t exist yet. They need to be developed before 2027. If you have licenses spanning multiple jurisdictions, watch for CDTFA guidance closely.

There’s also a good-faith protection built in. If a retailer uses a customer’s address information in good faith and that information turns out to be inaccurate, the retailer isn’t liable for the resulting error. But good faith means you actually tried. Documenting your sourcing methodology will matter if you’re ever audited.

The Anti-Rebate Provision

One additional piece worth flagging: SB 122 would prohibit any purchaser or retailer of digital products from entering into an agreement that would redirect, rebate, or divert Bradley-Burns local sales tax revenue from a digital product sale. Local agencies would face the same prohibition.

This closes a loophole some jurisdictions had used to attract retail operations, essentially agreeing to kick back local sales tax revenue to retailers as an economic incentive. That practice is now off the table for digital product transactions, full stop.

What You Should Be Doing Right Now

January 2027 feels distant. It isn’t. Here’s how to use the time you have.

Audit your software spend. Pull a complete list of your SaaS and software subscriptions. Categorize them: Is this prewritten software? Is it delivered electronically or accessed remotely? What’s the annual spend with each vendor? How many of your users or business locations are in California? This inventory is the foundation of everything else.

Check against the exclusions. Work through the carve-outs. Infrastructure-as-a-service, gaming products, digital media, digital books: if any of your software spend falls into those categories, document the basis for the exclusion. The burden of proof lives with the purchaser.

Identify your $5 million vendors. If you have any single software vendor where your California purchases could approach $5 million annually, flag that relationship now. Getting a use tax direct payment permit set up and filing a return directly with the CDTFA is a very different process than receiving a tax line on a vendor invoice. Your team needs time to build that workflow.

Talk to your vendors. Your software vendors are working through this too. They will need to update their billing systems, invoicing, and exemption certificate processes. Start the conversation early. Ask how they’re planning to handle California tax collection starting in 2027. If they don’t have an answer yet, that’s a signal to follow up.

Review your exemption certificate situation. If you currently hold resale certificates or other exemption documentation with software vendors, make sure those are current. You’ll want your records clean before the new rules take effect.

Get ahead of use tax exposure. If your company has been buying out-of-state software and not self-assessing California use tax, the new law makes that obligation explicit and enforceable. A voluntary disclosure approach, handled before an audit notice arrives, is almost always a better outcome than one that isn’t.

The Bottom Line

California’s SB 122 is not yet law. But it passed with broad legislative support as part of a consensus budget agreement, the governor is expected to sign it, and the January 1, 2027 effective date is fixed in the bill text. The gap between “expected to be signed” and “signed” is not a reason to wait.

The companies that will struggle are the ones treating this as something to revisit after the governor acts. The companies that won’t are the ones mapping their exposure now, having the right conversations with vendors and advisors, and building the internal processes to handle a new category of taxable spend before the deadline hits.

We are monitoring SB 122 closely and will update this article when the governor signs. If you want to understand your California digital products exposure before that happens, we’re happy to take a look.

The Bottom Line

California has been one of the last major states to bring software purchases clearly into its sales tax framework. The 2027 effective date gives businesses time to prepare, but that time is finite, and the compliance infrastructure you need to build doesn’t happen overnight.

The companies that will struggle are the ones that treat this as a 2026 problem. The companies that won’t are the ones mapping their exposure now, having the right conversations with vendors and advisors, and building the internal processes to handle a new category of taxable spend before the deadline hits.

If you’re not sure where your company stands on California digital products exposure, that uncertainty is itself the answer. This is a good time to get clarity.

If your business files in multiple states, “federal taxable income” isn’t a fixed number. Each state decides independently whether to adopt federal tax code changes, lock in an older version, or pick specific provisions to accept or reject. The result is a patchwork that requires separate tracking, separate calculations, and separate documentation for each state — even when you’re starting from the same federal return.

2026 is a particularly active year because of the One Big Beautiful Bill Act (OBBBA), signed July 4, 2025. The OBBBA made most TCJA provisions permanent, restored 100% bonus depreciation, created immediate expensing for domestic research and experimental costs, and modified the business interest deduction limitation under §163(j), among other changes. Every state with an income tax is now deciding whether to adopt those changes, decouple from them, or wait.

Some acted quickly. Others are still working through it. And for multistate businesses, the variation in how states are responding — combined with their underlying conformity approaches — determines how you calculate taxable income in each state you file.

This guide covers what conformity actually means, where the states in the table below stand heading into mid-2026, and how to build a compliance process that accounts for these differences.

What Is State Tax Conformity?

Most states use federal taxable income as the starting point for calculating state tax liability. When Congress changes the federal tax code, each state has to decide what to do with that change.

The answer to that question determines how you calculate depreciation, handle business interest deductions, treat research and experimental costs, and manage dozens of other line items on your state returns.

States generally fall into three categories.

Rolling conformity states automatically adopt federal tax code changes as they happen. When Congress amends the IRC, these states incorporate those changes without requiring separate state legislation — unless they specifically decouple from a provision. Rolling conformity states can still carve out exceptions, and several did exactly that in response to the OBBBA. Examples include Colorado, Connecticut, Illinois, Massachusetts, New Jersey, and New York.

Static conformity states tie their tax code to a specific IRC date. They only update when state legislators pass new conformity legislation. This means the specific date matters enormously — a state with a January 1, 2025 conformity date is pre-OBBBA, while one that updates to a post-July 4, 2025 date generally picks up the new federal provisions unless it separately decouples. Examples include California, Florida, Georgia, and Indiana.

Selective conformity states build their own tax base and adopt only specific IRC sections. They don’t start from federal taxable income at all, so federal changes don’t flow through automatically in any form. Alabama, Arkansas, Mississippi, New Jersey, and Pennsylvania use variations of this approach for corporate income tax purposes.

The practical effect: in a rolling conformity state, you need to know what the state has specifically decoupled from. In a static conformity state, you need to know the conformity date and whether the state has updated it to cover recent federal law. In a selective conformity state, you need to understand which IRC provisions the state actually incorporates.

Why 2026 Is Particularly Complex

The OBBBA changed the federal baseline significantly. The One Big Beautiful Bill Act, signed July 4, 2025, made permanent most TCJA provisions that were previously temporary, restored 100% bonus depreciation (previously phasing down), created immediate domestic R&E expensing under new §174A, modified §163(j) business interest limitations, and increased §179 expensing limits. Every state now has to decide what to do with each of these changes. Many have acted; many have not.

States responded unevenly and quickly. Several states decoupled from OBBBA provisions during 2025 legislative sessions — before many businesses had even begun planning for 2025 returns. Michigan, Colorado, Rhode Island, Virginia, and several others moved fast. Others are still evaluating. The 2026 legislative sessions are seeing additional conformity action in both directions.

Mid-year changes disrupt planning. When states update conformity dates or decouple from provisions mid-year, estimated tax payments already made may be based on different rules than the remainder of the year requires. Virginia, for example, enacted its conformity update on February 20, 2026, affecting the 2025 and 2026 tax years.

Nexus footprints keep expanding. As businesses maintain distributed workforces, more states mean more conformity variations to track. A company that filed in twelve states last year might file in eighteen this year, each with its own approach to the OBBBA and underlying conformity position.

2026 State Tax Conformity Reference Table

This table reflects conformity positions as of mid-2026 based on available guidance. Conformity dates and positions change when legislatures act — verify current status before filing, and check for OBBBA-specific guidance in each state.

Important: This table is a general reference. Many states have additional modifications and adjustments that add to or subtract from federal income beyond their baseline conformity position. The OBBBA conformity landscape is still actively evolving — verify current positions with state tax authorities or a qualified advisor before filing.

Building a Compliance Strategy

Map your filing obligations first. Before you can manage conformity differences, you need a clear picture of where you have nexus and filing requirements. For each state, identify the conformity type, the current IRC date, known decoupling provisions that affect your business, and any pending conformity legislation. This map becomes the foundation for everything else.

Track key provisions separately. Certain federal provisions trigger the most state-level differences and require their own tracking systems.

Depreciation and bonus depreciation. The OBBBA restored 100% bonus depreciation federally, but multiple states decoupled from this — Michigan, Illinois, Colorado, Pennsylvania, and others. You may need to maintain separate depreciation schedules under multiple IRC versions simultaneously.

Research and experimental costs. The OBBBA created §174A, allowing immediate expensing of domestic R&E. California, Michigan, Virginia, and others have decoupled from this. States that previously decoupled from the TCJA-era §174 capitalization requirement have their own existing R&E rules that may differ from both pre- and post-OBBBA federal treatment.

Business interest limitations. §163(j) was modified by the OBBBA. Michigan and Wisconsin, among others, apply pre-OBBBA limits. Track §163(j) calculations separately for states where the OBBBA changes don’t apply.

Net operating losses. Carryforward and carryback rules vary by state. Document amounts under both federal and state rules.

Build flexibility into estimated payments. Mid-year conformity changes — like Virginia’s February 2026 update — can mean that Q1 and Q2 estimates were calculated under different rules than Q3 and Q4 require. Review state legislative calendars for pending conformity bills, build contingency into estimates for states actively debating their OBBBA response, and document your calculation methodology so adjustments are straightforward when changes occur.

Set up a monitoring process. Staying current requires ongoing attention. Track state revenue department announcements, monitor legislative activity in your filing states, and update your conformity map when changes occur. The OBBBA conformity situation is still developing through 2026 legislative sessions.

Document everything. For each state, keep records of the conformity date used in your calculations, any state-specific adjustments, the source of your conformity determination, and calculations showing how you arrived at state taxable income. This protects you in audits and simplifies year-over-year comparisons.

Common Mistakes

Assuming federal equals state. Even rolling conformity states often have modifications that require separate calculations. A 2026 federal return with 100% bonus depreciation and immediate R&E expensing may look very different from your Michigan or Illinois returns for the same year.

Missing OBBBA-specific decoupling. A state might have rolling conformity but still decouple from specific OBBBA provisions. Illinois is a good example — rolling conformity, but decoupled from §§168(k) and 168(n). The conformity type alone doesn’t tell the whole story.

Using outdated conformity information. Indiana updated its conformity date to January 1, 2026 in March 2026. Virginia established a new static date of December 31, 2025 in February 2026. Ohio updated to March 7, 2025. Relying on last year’s research without verifying current status is a meaningful source of errors in 2026.

Missing amended return requirements. When conformity changes affect previously filed returns, some states require amendments while others allow adjustments on the current year return. Virginia’s HB 29 specifically addresses the 2025 and 2026 tax years — businesses that had already filed or made estimated payments based on the prior approach may need to act.

Underestimating depreciation complexity. Depreciation differences compound over time. A business that doesn’t track state-specific depreciation from the start faces significant reconstruction work when differences need to be calculated years later. The OBBBA’s return to 100% bonus depreciation — and the states that declined to follow — makes this more acute heading into 2026.

When to Bring in Outside Help

A few signs that outside support makes sense: your nexus footprint is expanding and you’re adding multiple new filing states each year; you’re dealing with significant asset purchases or transactions that interact with conformity rules across states; you’ve received audit notices or state inquiries about your calculations; or your internal team is stretched thin and conformity tracking is pulling capacity away from strategic work.

The OBBBA conformity situation is genuinely complex in 2026. States are still responding, guidance is still being issued, and positions are still changing. If you’re uncertain whether your state calculations properly account for current conformity positions, a review is worth the investment before you discover the gap during an audit.
