Letter Requesting Information
The Audit Division may request additional information from a business while their return is under review.

Notice of Proposed Tax Adjustment / Notice of Tax Due
A Notice of Proposed Tax Adjustment is sent when the Audit Division has determined an additional tax is due. The Notice lists the amount plus any penalties and interest.
Action Required
If the business agrees with the stated amount, the balance due should be paid within 30 days of the date on the Notice.
A business who disagrees should send a reply with related documentation within 30 days of the Notice date.
If there was a payment error, proof of payment must be sent with your reply. If the payment was made by bank check, send a photocopy of the front and back of the cancelled check. Obtain and send a copy of the cancelled money order from the place where it was purchased.

Notice of Determination
If we do not receive a response to the first Notice within the 30 day due date (see above), Finance will decide what taxes a business should pay. A Notice of Determination will then be sent. In these cases the amount of tax will be based on all available information, such as Finance’s past records and Federal Tax Returns, etc.
Action Required
A business representative has 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:
Notice and Demand for Payment
If a business has not responded to letters sent by Finance, we will issue a Notice and Demand for Payment. Failure to act at this time will result in the beginning of collection procedures.

Action Required
A business must respond within 30 days of the date on this Notice, by either;
- Filing the return and/or payment; or

Notice of Refund Disallowance
The Notice of Disallowance or Partial Disallowance is sent by Finance after a refund request has been examined, and all or part of it is denied. The Notice explains the reasons for this decision.
Deadlines to Appeal a Notice of Disallowance
General Corporation and Unincorporated businesses have two years from the date stated on the Notice of Disallowance. They must either file a Request for a Conciliation Conference or a petition for a Tax Appeals Tribunal Hearing.
All other businesses have 90 days from the date stated on the Notice to either seek a Conciliation Conference or file a petition with the Tribunal.
The disallowance or partial disallowance becomes final if the business does not choose either of the above options by the deadline. No further review will be available without good reason.
