Taxpayers who discover an error after filing a federal tax return may need to file an amended return. There are some instances where an amended return isn’t required such as when the IRS corrects errors during processing or requests missing forms or schedules separately.
Reasons to file an amended return
If there are changes to key items on the original return, including:
•Filing status
•Income
•Deductions
•Credits
•Dependents
•Tax liability
Time limits
To claim a refund, an amended return must generally be filed within:
•Three years from the date the original return was filed, or
•Two years from the date the tax was paid, whichever is later
If the original return was filed early, the three-year period begins from the April tax deadline. Special rules apply when there are net operating losses, foreign tax credits, bad debts or other issues. Additionally, taxpayers in disaster relief situations, combat zone service, have bad debts, foreign tax credits, or loss or credit carrybacks, may have more time to file an amended return.
How to file an amended return
Taxpayers must file Form 1040-X, Amended U.S. Individual Income Tax Return. When filing, they should:
•Submit a corrected Form 1040, 1040-SR, or 1040-NR for the applicable tax year
•Attach any supporting documents and updated forms or schedules
Refunds and payments
For tax years 2021 and later, taxpayers may request direct deposit of refunds when filing electronically. If additional tax is owed, payment should be submitted with the amended return. The amended return replaces the original return, and the IRS will calculate any applicable penalties or interest if filed after the due date.
Status of amended return
Taxpayers can check the status of an amended return approximately three weeks after it’s submitted. It generally takes 8 to 12 weeks for it to be processed. However, in some cases, processing could take up to 16 weeks.
State tax considerations
Changes to a federal return may affect a taxpayer’s state tax liability. Taxpayers should contact their state tax agency for guidance and should not attach state returns to the federal amended return.

Extensions of time to file your tax return
You may request up to an additional 6 months to file your U.S. individual income tax return. There are three ways to request an automatic extension of time to file your return. You must request the extension of time to file by the due date of your return to avoid the penalty for filing late. An extension of time to file is not an extension of time to pay. You may file your request for an extension in any one of three ways listed below:
1.Pay all or part of your estimated income tax due and indicate that the payment is for an extension of time to file your return.
2.File Form 4868.
If you file the Form 4868 electronically, be sure to have a copy of your prior year's return; you'll be asked to provide your prior year's adjusted gross income (AGI) amount for verification purposes. Once you file, you'll receive an electronic acknowledgement that the IRS has accepted your filing. Keep this for your records.
Out of the country – You're allowed two extra months (generally until June 15) to file your return and pay any tax due without requesting an extension if you're a U.S. citizen or resident alien, and on the due date of your return you're either:
1.Living outside of the United States and Puerto Rico, and your main place of business or post of duty is outside of the United States and Puerto Rico, or
2.In military or naval service on duty outside of the United States and Puerto Rico.
For additional information, refer to Publication 54, Tax Guide for U.S. Citizens and Resident Aliens Abroad. If you use this automatic 2-month extension, you must attach a statement to your return explaining which of the two situations qualify you for the extension. You'll still have to pay interest on any tax not paid by the unextended due date of your return. You can also receive an additional 4-month extension of time to file (or, a total of six months) if you file Form 4868 and check the box on line 8 to indicate that you need an additional 4 months to file your return. The additional 4-month period is not an extension of time to pay.

Common tax return mistakes to avoid
Mistakes and errors can happen, but most are easily avoidable when it comes to filing federal income tax returns. Taxpayers are encouraged to review their entire return before filing to make sure it is correct and complete. This is the case even if someone else prepared it, because ultimately, it’s the taxpayer’s responsibility to ensure the information on the return is accurate.
Here are just a few common errors that can be avoided:
•Incorrect filing status: Be sure to select only one filing status and make sure it is the correct one.
•Inaccurate information: Taxpayers should carefully when entering any wages, dividends, bank interest and other income they receive to make sure they report the correct amounts.
•Misspelled names or missing social security numbers: All names and taxpayer identification numbers must be provided for everyone listed on the return. Social security numbers and names should be entered exactly as they appear on each person’s Social Security card. If there have been any name changes, be sure to contact the Social Security Administration at SSA.gov or call them at 800-772-1213.
•Credits and deductions: There are several new deductions and changes to certain credits for 2026. Taxpayers should make sure any deductions and credits are calculated correctly, and necessary documentation is provided.
•Unsigned return: An unsigned return is considered invalid. If it’s a joint return, both must sign and date.
•Incorrect bank account information: Taxpayers who are owed a refund should choose direct deposit. This is the fastest way for them to get their money. However, taxpayers need to make sure they use the correct routing and account numbers on their tax return.
