Sales tax penalties and interest, state by state
Late sales tax returns can lead to percentage penalties, flat charges and interest. This guide covers 17 states using their official publications. Read each state’s conditions: a notice, payment date or shared cap can change what is due.
The short answer
A late return can involve a late filing penalty, a late payment penalty and interest. These are different categories, but they do not always stack. Some states use a shared cap or a single penalty for either failure.
Filing and payment are separate obligations. Check both deadlines, including the requirement to file a zero return, and read the applicable state rule before calculating a charge.
What each state charges
Sorted alphabetically. Every figure below is taken from the state revenue department's own publication, linked on each state page along with the date we last verified it.

Do not overlook zero returns
Once you are registered, the obligation is to file every period on your assigned schedule. It is not to file only in periods where you owe something. A seller who registers in a state, has a quiet quarter, and simply does not file may still incur a flat penalty even though the tax for that period is zero.
Texas charges $50 for each late report and says explicitly that it applies even if the report is filed later and even if no taxes are due. Florida requires a return for each reporting period even if no tax is due, with a $50 floor. Illinois’s second-tier nonfiling penalty can apply with no tax due, but only if a return remains unfiled 30 days after a notice of nonfiling.
If you have stopped selling into a state for good, closing the registration properly is what ends the obligation. Going quiet does not.
How states set interest
Interest is separate from the penalty, runs until the balance is paid, and follows one of three patterns.
- Indexed to a federal rate. California charges the IRS rate plus 3%, calculated monthly. Illinois resets on January 1 and July 1 from the underpayment or short-term rate under section 6621 of the Internal Revenue Code.
- A fixed annual number. Minnesota publishes 7% for 2026.
- Variable, set each January. Texas determines its rate at the beginning of each calendar year.
When interest starts also varies. Ohio runs it from the original due date with no grace period. Texas does not start until the 61st day after the report due date.
Before you rely on any of this
These figures are a starting point for a conversation with your accountant, not a substitute for one. Penalty rates, interest rates and filing rules change by legislative session, and several states index interest to a federal rate that moves twice a year.
Every state page here links the department publication it was built from and shows the date the figures were last checked. Verify against that source before you file, amend, or respond to a notice.
Coverage is deliberately partial. We publish a state after reading that state's own publication, never from an aggregator or from a figure that turns out to belong to a different tax. More states are added as they are verified.

How to review a late sales tax notice
Use this checklist with your accountant. Keep the filing and payment records together and confirm the state’s rules for the period covered by the notice.
- 1
Check the notice and reporting period
Match the state notice to the return, payment confirmation and reporting period. Record any response or appeal deadline.
- 2
Identify each charge
Separate tax, late-filing penalties, late-payment penalties and interest. Check shared caps, minimums and notice prerequisites before adding them together.
- 3
Confirm the rate and dates
Use the department’s current guidance for the relevant period. Interest rates, extensions and relief programs may change the result.
- 4
Resolve outstanding obligations
Work with your accountant and the department to file missing returns, make payment arrangements and request any relief for which you qualify.
- 5
Keep the supporting records
Retain the return, receipt, notice and correspondence, and update your filing calendar for every open registration.
Frequently asked questions
Can a sales tax penalty be more than the tax I owed?
Yes. Texas and Florida publish $50 late-return penalties even when no tax is due. Illinois has a $250 second-tier nonfiling floor, but it applies only if the return remains unfiled 30 days after a notice of nonfiling. Conditions matter as much as the percentage.
Do I have to file a sales tax return if I had no sales?
A registered seller generally must file for each assigned reporting period. Texas, Florida and New York publish charges for late zero returns. Check your registration and filing schedule with the state before skipping a period.
Are late filing and late payment penalties always added together?
No. Some states assess separate charges, while others apply a shared cap or one rule for either failure. California caps its ordinary late-return and late-payment combination at 10% of the tax due. Read the state-specific conditions before adding any amounts.
How do states set interest on unpaid sales tax?
The rules vary. California generally uses the IRS rate plus 3 percentage points; Illinois reviews its federal-rate-based interest twice a year; Georgia uses the Federal Reserve prime rate plus 3 percentage points. Minnesota publishes 7% for 2026. Always check the rate for the period of the debt.
Does interest start from the due date?
The start date depends on the state. Ohio’s UST-1 instructions say interest accrues from the tax due date. Texas begins interest on the 61st day after the report due date. Interest can be due in addition to a penalty.
How does Washington’s late-payment penalty increase?
It starts at 9% when tax is not paid by the due date. It rises to 19% after the last day of the following month, and 29% after the last day of the second month following the due date. Use those calendar boundaries, not a fixed number of days.
Can these penalties be waived?
Sometimes. Each state has its own grounds and procedure. Washington allows relief for circumstances beyond the taxpayer’s control and has a separate route for one return after 24 months of timely filing and payment. Georgia directs waiver requests through the Georgia Tax Center. Check the source for the state and your circumstances.
Why does this page not cover all 50 states?
This guide covers only the states in the source-checked dataset. A missing state means it is not covered here, not that no penalty applies. Each published state page links its source and shows its verification date.
