Amend a Return

If you discover an error on a previously filed return, you should file an amended return and pay any additional tax or fee due, including interest. If you have questions, please contact our Taxpayer Information Section at 1-800-400-7115.

For assistance in calculating the interest due use the Interest Rate Calculator.

If your amended return results in a refund, please read Publication 117, Filing a Claim for Refund.

Please see instructions below based on the type of return you wish to amend.
