Notice of Proposed Assessment Your tax audit

Upon completion of the audit, we mail a Notice of Proposed Assessment (NPA) to you if you owe additional:

  • Tax
  • Penalties
  • Interest

This notice is not a bill. Your balance due will become a bill if you take no action by the protest by date. If you agree with the proposed amount, pay your NPA.

If you disagree with the audit findings, you can file a protest by the protest by date shown on the front of the NPA. You have 60 days to protest.

Filing a protest will not stop the accrual of interest on the NPA. To stop the accrual of interest, pay your NPA balance in full within 15 days of the notice date.

For more information about the NPA process, review the following:
