id="en_US_2025_publink1000170691"> Completing Form 1040-X. On Form 1040-X, enter your income, deductions, and credits as you originally reported them on your return; the changes you are making; and the corrected amounts. Then, figure the tax on the corrected amount of taxable income and the amount you owe or your refund. If you owe tax, the IRS offers several payment options. See How To Pay , earlier. The tax owed won’t be subtracted from any amount you had credited to your estimated tax. If you can’t pay the full amount due with your return, you can ask to make monthly installment payments. See Installment Agreement , earlier. If you overpaid tax, you can have all or part of the overpayment refunded to you, or you can apply all or part of it to your estimated tax. If you choose to get a refund, it will be sent separately from any refund shown on your original return. Filing Form 1040-X. When completing Form 1040-X, don’t forget to show the year of your original return and explain all changes you made. Be sure to attach any forms or schedules needed to explain your changes. File a separate form for each tax year involved. You can file Form 1040-X electronically to amend Form 1040 and 1040-SR for the current year or the two prior tax periods. For more information, see Instructions for Form 1040-X. If you must mail your Form 1040-X, mail it to the Internal Revenue Service Center serving the area where you now live (as shown in the Instructions for Form 1040-X). However, if you are filing Form 1040-X in response to a notice you received from the IRS, mail it to the address shown on the notice. Time for filing a claim for refund. Generally, you must file your claim for a credit or refund within 3 years after the date you filed your original return or within 2 years after the date you paid the tax, whichever is later. Returns filed before the due date (without regard to extensions) are considered filed on the due date (even if the due date was a Saturday, Sunday, or legal holiday). These time periods are suspended while you are financially disabled , discussed later. If the last day for claiming a credit or refund is a Saturday, Sunday, or legal holiday, you can file the claim on the next business day. If you don’t file a claim within this period, you may not be entitled to a credit or a refund. Federally declared disaster. If you were affected by a federally declared disaster, you may have additional time to file your amended return. See Pub. 556 for details. Protective claim for refund. Generally, a protective claim is a formal claim or amended return for credit or refund normally based on current litigation or expected changes in tax law or other legislation. You file a protective claim when your right to a refund is contingent on future events and may not be determinable until after the statute of limitations expires. A valid protective claim doesn’t have to list a particular dollar amount or demand an immediate refund. However, a valid protective claim must: Be in writing and signed; Include your name, address, SSN or ITIN, and other contact information; Identify and describe the contingencies affecting the claim; Clearly alert the IRS to the essential nature of the claim; and Identify the specific year(s) for which a refund is sought. Mail your protective claim for refund to the address listed in the Instructions for Form 1040-X under Where To File. Generally, the IRS will delay action on the protective claim until the contingency is resolved. Limit on amount of refund. If you file your claim within 3 years after the date you filed your return, the credit or refund can’t be more than the part of the tax paid within the 3-year period (plus any extension of time for filing your return) immediately before you filed the claim. This time period is suspended while you are financially disabled , discussed later. Tax paid. Payments, including estimated tax payments, made before the due date (without regard to extensions) of the original return are considered paid on the due date. For example, income tax withheld during the year is considered paid on the due date of the return, which is April 15 for most taxpayers. Example 1. You made estimated tax payments of $500 and got an automatic extension of time to October 15, 2022, to file your 2021 income tax return. When you filed your return on that date, you paid an additional $200 tax. On October 15, 2025, you filed an amended return and claimed a refund of $700. Because you filed your claim within 3 years after you filed your original return, you can get a refund of up to $700, the tax paid within the 3 years plus the 6-month extension period immediately before you filed the claim. Example 2. The situation is the same as in Example 1 , except you filed your return on October 30, 2022, 2 weeks after the extension period ended. You paid an additional $200 on that date. On October 30, 2025, you filed an amended return and claimed a refund of $700. Although you filed your claim within 3 years from the date you filed your original return, the refund was limited to $200, the tax paid within the 3 years plus the 6-month extension period immediately before you filed the claim. The estimated tax of $500 paid before that period can’t be refunded or credited. If you file a claim more than 3 years after you file your return, the credit or refund can’t be more than the tax you paid within the 2 years immediately before you file the claim. Example. You filed your 2021 tax return on April 15, 2022. You paid taxes of $500. On November 5, 2023, after an examination of your 2021 return, you had to pay an additional tax of $200. On May 12, 2025, you file a claim for a refund of $300. However, because you filed your claim more than 3 years after you filed your return, your refund will be limited to the $200 you paid during the 2 years immediately before you filed your claim. Financially disabled. The time periods for claiming a refund are suspended for the period in which you are financially disabled. For a joint income tax return, only one spouse has to be financially disabled for the time period to be suspended. You are financially disabled if you are unable to manage your financial affairs because of a medically determinable physical or mental impairment that can be expected to result in death or that has lasted or can be expected to last for a continuous period of not less than 12 months. However, you aren’t treated as financially disabled during any period your spouse or any other person is authorized to act on your behalf in financial matters. To claim that you are financially disabled, you must send in the following written statements with your claim for refund. A statement from your qualified physician that includes: The name and a description of your physical or mental impairment; The physician’s medical opinion that the impairment prevented you from managing your financial affairs; The physician’s medical opinion that the impairment was or can be expected to result in death, or that its duration has lasted, or can be expected to last, at least 12 months; The specific time period (to the best of the physician’s knowledge); and The following certification signed by the physician: “I hereby certify that, to the best of my knowledge and belief, the above representations are true, correct, and complete.” A statement made by the person signing the claim for credit or refund that no person, including your spouse, was authorized to act on your behalf in financial matters during the period of disability (or the exact dates that a person was authorized to act for you). Exceptions for special types of refunds. If you file a claim for one of the items in the following list, the dates and limits discussed earlier may not apply. These items, and where to get more information, are as follows. Bad debt. See Pub. 550. Worthless security. See Pub. 550. Foreign tax paid or accrued. See Pub. 514. Net operating loss carryback. See Form 172 and the Instructions for Form 172. Carryback of certain business tax credits. See Form 3800. Claim based on an agreement with the IRS extending the period for assessment of tax. Processing claims for refund. Claims are usually processed 8–12 weeks after they are filed. Your claim may be accepted as filed, disallowed, or subject to examination. If a claim is examined, the procedures are the same as in the examination of a tax return. If your claim is disallowed, you will receive an explanation of why it was disallowed. Taking your claim to court. You can sue for a refund in court, but you must first file a timely claim with the IRS. If the IRS disallows your claim or doesn’t act on your claim within 6 months after you file it, you can then take your claim to court. For information on the burden of proof in a court proceeding, see Pub. 556. The IRS provides a direct method to move your claim to court if: You are filing a claim for a credit or refund based solely on contested income tax or on estate tax or gift tax issues considered in your previously examined returns, and You want to take your case to court instead of appealing it within the IRS. When you file your claim with the IRS, you get the direct method by requesting in writing that your claim be immediately rejected. A notice of claim disallowance will be sent to you. You have 2 years from the date of mailing of the notice of claim disallowance to file a refund suit in the U.S. District Court having jurisdiction or in the U.S. Court of Federal Claims. Interest on refund. If you receive a refund because of your amended return, interest will be paid on it from the due date of your original return or the date you filed your original return, whichever is later, to the date you filed the amended return. However, if the refund isn’t made within 45 days after you file the amended return, interest will be paid up to the date the refund is paid. Reduced refund. Your refund may be reduced by an additional tax liabilit
