How to Modify a Tax Return
- 1). Visit the IRS website and obtain a Form 1040-X. Form 1040-X, Amended U.S. Individual Income Tax Return, is used to correct an income tax return that was previously filed with the IRS.
- 2). Enter your personal information into the top portion of the form. Ensure that your phone number is correct in the event the IRS needs to contact you with further questions.
- 3). Choose a filing status, enter the year of the return you are amending and explain the reason for filing the amended tax return.
- 4). Complete the return by entering the correct information in the Income and Deductions, Tax Liability, Payments, Refund and Exemptions sections. Most of this information can be found on your previously filed return. Only complete the Exemptions section if you are increasing or decreasing the number of exemptions or exemption amount for housing individuals of a disaster.
- 5). Sign and date the form. If you are married, your spouse must also sign and date the form.
- 6). Attach any forms supporting the amendment. These may include Forms W-2s, W-2c, W-2G, 1099-R and Form 2439.
- 7). Mail the Form 1040X, supporting documents and a check or money order (if applicable) to the IRS. You can locate the appropriate address by using the IRS website (see Resources).
