How to Deregister From a State's Sales Tax — Step by Step

·Nexus by State

Many sellers register in a state, scale down or pivot, and find themselves below the economic nexus threshold — yet still filing returns monthly. If you're no longer required to collect, you can request deregistration. The process varies by state but generally follows the same five steps.

Five-step deregistration process

  1. Confirm you're below threshold. Most states require being below the dollar (and transaction) threshold for a full calendar year before allowing deregistration. Check rolling 12 months of revenue.
  2. File all outstanding returns. You can't deregister if you have missing filings. File any zero returns for past periods first.
  3. Pay any outstanding tax + penalties. States won't close your account with open balances.
  4. Submit a deregistration request. Either through the DOR online portal, a specific form (varies — often called a “Cancellation Form” or “Close Business Account”), or a written letter.
  5. File a final return. Some states require a separate “final” return covering the period from the last regular filing to the deregistration date. Check for this box on the return form.

Common pitfalls

Use the calculator to verify

Before deregistering, run your numbers through the nexus calculator and verify you're safely below the threshold. If you're close, consider waiting another quarter before submitting.
