How far back can you recover overpaid taxes?

In most states, we can review and file for refunds on transactions going back three to four years, depending on the statute of limitations in that jurisdiction.

Is there any risk or upfront cost involved?

No. Our recovery service is 100% success-based—you don’t pay anything unless we identify and secure a refund for you. There are no hidden fees or obligations.

What is a reverse sales tax audit?

A reverse sales tax audit is a review of past purchases and expenses to identify overpaid sales or use tax. Unlike a typical audit by the state, this process helps your business recover money you may have unknowingly overpaid.

What information do you need from us to get started?

We typically require Accounts Payable data, including fixed asset and expense reports, along with access to vendor invoices and tax-exempt documentation (if applicable). Our team guides you step-by-step through what’s needed with minimal disruption to your team.
