How do I file an amended federal return (Form 1040X)?

When do I need to file an amendment?

You may need to file an amended return if there are any changes to:

Use Form 1 040X (Amended U.S. Individual Income Tax Return) to correct any previously filed return, or if you are claiming any carryback due to a loss or unused credit.

There may be special rules that apply to refund claims relating to:

  • Net operating losses
  • Foreign tax credits
  • Bad debts
  • Other issues

  • You can't file an amended tax return electronically under the e-file system
  • Attach copies of any forms or schedules affected by the change
  • Include any form or schedules that support changes made on your return. This may include any Form W-2 received after the original filing, any Form W-2G or 1099 if income tax was withheld, or any other forms or schedules.
  • You will need to to file a separate Form 1040X for each tax year you're amending. Mail each Form 1040X in a separate envelope.
  • Be sure to enter the year of the return you're amending at the top of Form 1040X
  • The form has three columns:
      • Column A shows original figures (the original return) or adjusted figures (prior amendments or exam changes)
      • Column C shows the corrected figures (what they should be)
      • Column B is the difference between Columns A and C
  • A change to your federal tax return may affect your state tax liability. Generally, if you are amending your federal tax return, you should also file an amended state return.

Deadline to amend your federal tax return

If you are claiming a tax return with an amended federal tax return, the IRS typically requires the amended return to be filed within 3 years of the filing date of the original tax return (including extensions), or within 2 years of the date you paid the tax, whichever is later.

How long will it take the IRS to process my amended federal tax return?

It typically take the IRS between 8 and 12 weeks to process amended returns from the date your Form 1040X is received by the IRS via postal mail.

Where’s the refund from my amended return?

  • You can check the status of your Form 1040X (PDF) using the Where's My Amended Return? online tool or the toll-free telephone number 866-464-2050 three weeks after you file your amended return.
  • Once your amended return has been processed (typically 8-12 weeks), you will receive any additional refund you are owed.
  • If it has been over 12 weeks and you still have not received your amended refund check, you can find more information about your refund by calling the IRS customer support line at 1-800-829-1040.

Tip: When calling the IRS customer support line, you can press 1 (for English), then press 0 (zero), and you should be able to talk to a live person at the IRS. The best time to reach the IRS is between 7-9 AM and 6-7 PM, Monday-Friday.

Where do I send my amended return?

When mailing a Form 1040X to file an amended federal tax return:

  • Remember to sign your amended return before you mail it to the IRS!
  • If the changes involve any additional forms or schedules, attach that schedule or form to the amended return
  • If your amended return is claiming an additional refund, you should typically wait until you have received your original refund before filing Form 1040X. You may cash that check while waiting for any additional refund.
