Audit Notices

If you pay business taxes to the Department of Finance, you may receive one or more notices from our Audit Division. They are listed below. You should make sure to read the notices carefully and respond as instructed on the notice. Please mail any responses to the address shown on the notice.

The Department of Finance will send the Consent to Audit Adjustment(s) with the Notice of Proposed Tax Adjustments, or when you accept the audit findings mailed to you with the workpaper cover. The Consent to Audit Adjustment(s) lists the tax due plus any interest and penalties. You will also receive a Payment Transmittal Form with instructions for making your payment.

A Consent and Waiver is sent to you when the audit has been settled. The Consent and Waiver lists the tax due plus any interest and penalties. You will also receive a Payment Transmittal Form with instructions for making your payment.


DOF issues a Consent Determination at the conclusion of the audit in confirmation of the Consent to Audit Adjustment(s) or Consent and Waiver. A Consent Determination lists the tax due plus interest and penalties.

A Notice of Determination is issued at the conclusion of the audit if you do not agree to the audit findings or if you did not respond to the Information Document Request(s) or Notice of Proposed Tax Adjustment. A Notice of Determination lists the tax due plus interest and penalties. In these cases the amount of tax will be based on all available information, including federal tax returns and the past records of the Department of Finance.

You or your representative have 90 days from the date stated on the Notice of Determination (or 150 days if the notice is addressed outside the US) to decide which of the following options to choose:

  • Pay the tax shown.
  • File a Request for a Conciliation Conference.
  • Petition for a Tax Appeals Tribunal hearing.

If you fail to respond to a Notice of Determination within the required period, DOF will issue a Notice and Demand for Payment, which marks the beginning of collection procedures.

The Department of Finance sends this notice at the end of an examination of your tax return if no adjustments were necessary.

The Department of Finance sends this notice after a refund request has been examined and all or part of the refund is denied. The notice explains the reasons for this decision.

  • Deadlines to Appeal a Notice of Disallowance
    • If you receive a denial of a refund claim for general corporation, banking corporation, or unincorporated business taxes, you have two years from the date on the Notice of Disallowance to file a Request for Conciliation Conference or a Petition for Hearing with the Tax Appeals Tribunal.
    • If you receive a denial of a refund claim for any other tax, you have 90 days from the date on the Notice of Disallowance to file a Request for Conciliation Conference or a Petition for Hearing with the Tax Appeals Tribunal.
    • The disallowance or partial disallowance becomes final if you do not appeal by the deadline.
