What Is a Sales Tax Penalty?
A sales tax penalty is a charge for not meeting your state or local sales tax obligations, like missing a filing deadline, underpaying, or not filing at all. Penalties are separate from interest, which accrues on the unpaid balance over time. Together, they make up sales tax penalties and interest.
Some commonly asked questions:
What is the penalty for not paying sales tax?
If your business fails to pay the full amount of sales tax owed, you can expect a penalty that typically ranges from 5% to 25% of the unpaid tax amount. The exact percentage depends on how late the payment is and the specific rules in your state.
Some states increase the penalty the longer the payment remains outstanding, while others cap the maximum amount after a certain period. In addition to the penalty, interest will begin to accrue on the outstanding balance from the date the tax was due.
What is the penalty for filing sales tax late?
Filing your sales tax return late (even if no tax is due) can still trigger a penalty. Many states assess a flat fee for late filings, while others calculate a percentage based on the amount of tax owed.
For example, a state might impose a 5% penalty if the return is filed within 30 days after the due date and increase it to 10% if the return is more than 30 days late. Penalties for late filing are often applied in addition to penalties for late payment, compounding the total amount you could owe.
What is the penalty for not collecting sales tax?
Failing to collect sales tax when you’re required to is one of the most serious compliance issues a business can face. In many cases, you may be held liable for the uncollected tax as if you had received it. That means you’ll have to pay the amount owed out of pocket—plus potential penalties and interest.
In more severe situations, states may view this as intentional evasion and impose heavier fines or even criminal charges. States take the responsibility to collect and remit sales tax seriously, so it’s essential to understand when your business is required to collect it based on nexus rules.
Common Types of Sales Tax Penalties
Late filing penalties
These are assessed when a business fails to file its sales tax return by the required due date. Even if no tax is owed, the state may still impose a flat penalty or a percentage of the tax due. Late filings can also lead to further scrutiny or an increased risk of audit.
Late payment penalties
If a return is filed but the tax due isn’t paid in full, most states will charge a late payment penalty. This is typically a percentage of the unpaid amount and can increase over time. Interest also begins to accrue on the outstanding balance until it is resolved.
Failure to collect or remit penalties
When a business fails to collect sales tax from customers or doesn’t remit it to the state, penalties can be severe. States may hold the business personally liable for the uncollected tax. In addition, penalties and interest will likely apply, increasing the total owed.
Sales tax evasion penalties
Evasion refers to deliberately avoiding sales tax obligations through fraud or misrepresentation. Penalties for evasion are often much higher and may include criminal charges. States may pursue fines, liens, or even jail time for intentional noncompliance.
Sales tax audit penalties
An audit can uncover reporting errors, underpaid tax, or misclassified transactions. If discrepancies are found, penalties and interest are usually added to the balance due. For instance, Florida can impose an audit-related penalty as high as 50% of the tax owed.
How Sales Tax Penalties Are Calculated
- Fixed penalties: A flat amount per incident.
- Percentage-based: A portion of unpaid tax that increases over time.
Many states offer a sales tax penalty calculator to estimate what you may owe.
How to calculate sales tax penalty and interest
- Start with the unpaid amount.
- Add penalty percentage.
- Add monthly interest.
Are sales tax penalties deductible?
Sales tax penalties are generally not deductible as business expenses on your federal tax return. The IRS views penalties as punishments for noncompliance, not as ordinary and necessary business costs. While you may deduct the underlying tax and interest, the penalties themselves must be excluded when calculating your tax liability.
What is the penalty fee in your state?
Penalty amounts vary widely by state, and many use both fixed and percentage-based models. For instance, Florida may charge a 10% penalty on the tax due, with a minimum fee of $50, and apply a 1% monthly interest rate until the balance is paid. It’s important to check your state’s Department of Revenue for current rates or use their online calculator to estimate what you owe.

How to Avoid or Waive a Sales Tax Penalty
How to waive sales tax penalty
Many states offer a one-time waiver or penalty relief if you can show reasonable cause. Common examples include medical emergencies, natural disasters, or unintentional errors by a tax professional. You’ll typically need to submit a formal request explaining your situation.
Sales tax penalty abatement letter
A penalty abatement letter is your opportunity to tell your side of the story. Clearly outline why the error happened, what steps you’ve taken to correct it, and include any supporting documents. The more transparent and professional your explanation, the better your chances for relief.
How to pay penalties online
Nearly every state provides an online portal where you can pay your sales tax, penalties, and interest. You’ll need to log in using your taxpayer account and select the appropriate period or notice number. If you’re unsure how much to pay, the system usually calculates it for you.
Sales Tax Penalties by Business Type
eCommerce and online sellers
Online sellers often trigger nexus in multiple states due to economic thresholds or third-party platforms. Missing registrations or failing to collect in these states can result in widespread penalties and back taxes. Staying ahead with regular nexus reviews is essential.
Vehicle and dealership sales
Automotive and dealership businesses are heavily regulated at the state level. Missing deadlines for registration, title fees, or tax remittance can lead to costly penalties like the Arkansas vehicle sales tax penalty. Proper tracking of in-state and out-of-state transactions is key.
Cash-based businesses
States often scrutinize cash-heavy businesses due to the higher risk of underreporting. If discrepancies are found between reported revenue and deposits, you may face up to a 10% penalty or more. Keeping clean records and depositing all cash income helps reduce audit risk.
