Sales tax audits statute of limitations

by TaxJar January 17, 2024


Please note: This blog was originally published in 2020. It’s since been updated for accuracy and comprehensiveness.

When states started taking action against declining sales tax revenue as a result of the pandemic, they began pursuing more sales tax audits, cracking down on businesses with economic nexus that are not collecting or remitting sales tax returns. Many experts believe we’ll continue to see an increase in sales tax audits in 2024.

Diane Yetter, of YETTER, said, “I think the states have started using data analytics to identify non registrants and that this will increase. It also might mean states that hadn’t pursued companies for not registering as of the [economic] nexus date will assess those taxpayers. A few states have already been doing that.”

If your business has received notice of a sales tax audit or assessment from a state, don’t panic. Prepare. Knowing the sales tax statute of limitations by state can help.

How far back can a state inspect my transactions and returns?

In the event of a sales tax audit, the first thing your business should do is determine the lookback period, or how far back an auditor can inspect your transactions and sales tax returns. This is known as the statute of limitations for a sales tax audit or assessment.

For example, if the statute of limitations on a sales tax audit in a state is 2 years, then the auditor can only look at transactions and returns 2 years from when the return was filed or the return due date.

Keep in mind: If there were instances of evasion, gross negligence, or fraudulent behavior, the statute of limitations for sales tax audits may not apply. If your business was not collecting and remitting sales tax in a state, but you knew you should be, the auditor could throw out the lookback period altogether. In many states, if the auditor believes that the tax base (or how much you could owe the state) is misrepresented by a certain amount (like 25%), then the statute of limitations can be increased.

What do I do if I owe sales tax?

First, determine your exposure, calculating how much tax you might owe to the state based on the sales tax percentage in that state and the number and amount of transactions in that state.

Then, explore any amnesty or Voluntary Disclosure Agreement (VDA) programs available in that state, which might limit the interest and penalties you would have to pay.

If you want to prepare your business for a sales tax audit, read our step-by-step guide, How to Handle a Sales Tax Audit, to learn what documents to collect, how to negotiate with the auditor, and more.

To prevent risk of a sales tax audit, automate filing sales tax returns on time and track when your business is approaching economic nexus in every state using TaxJar.
