If you live in Texas and are mailing a federal amended return, send Form 1040-X to: Department of the Treasury, Internal Revenue Service, Austin, TX 73301-0052. Texas has no individual state income tax, so there’s no state amendment to file alongside it. And before you print the envelope, check whether e-filing works for you, because the IRS now accepts most amended returns electronically and processes them faster.
The Austin Address for Form 1040-X
The IRS routes amended individual returns by the filer’s state. Texas residents go to the Austin service center:
Department of the Treasury
Internal Revenue Service
Austin, TX 73301-0052
The same address applies whether your amendment produces a refund or a balance due.1Internal Revenue Service. Where to File Addresses for Taxpayers and Tax Professionals Filing Form 1040-X No street address is needed; the ZIP code routes the mail inside the IRS campus.
If You’re Responding to an IRS Notice
One important exception: if the amendment is a response to a specific IRS notice you received, send it to the address printed on that notice instead of the Austin address. The notice address goes to the unit already handling your file.
How to Package the Envelope
Use a traceable mailing method. USPS Certified Mail with Return Receipt Requested gives you dated proof of mailing and delivery, which matters if the IRS later questions when you filed. Make a complete copy of the signed 1040-X and every attachment before sealing anything.
If you owe additional tax and are paying by check or money order, place the payment loosely in the envelope rather than stapling it to the form. Attach supporting documents the amendment relies on, such as a corrected W-2, a 1099, or an additional schedule.2Internal Revenue Service. Form 1040-X – Amended U.S. Individual Income Tax Return
Watch the small stuff that stalls returns: misspelled names, a wrong Social Security number, or a mistaken date of birth are the most common delays. Names and SSNs should match the Social Security card exactly, and on a joint return both spouses have to sign and date the form.3Internal Revenue Service.

You Can E-File Instead

The IRS accepts electronically filed Forms 1040-X for the current tax year and the two prior tax periods through most commercial tax software.4Internal Revenue Service.

If you e-file an amendment for tax year 2021 or later, you can have any refund sent by direct deposit.

If You Owe, Pay Separately and Pay Fast
You don’t have to wait for the IRS to process the amendment to pay what it shows you owe. Interest on an underpayment runs from the original due date of the return, not from the date you file the 1040-X, and a monthly failure-to-pay penalty accrues on top of that.6Internal Revenue Service.

After You Send It
Amended returns move slowly. The IRS expects 8 to 12 weeks of processing, and some take up to 16 weeks.9Internal Revenue Service.

The IRS “Where’s My Amended Return?” tool is the main way to track progress. You’ll need your Social Security number, date of birth, and the ZIP code from the return. The tool covers the current tax year and up to three prior years.11Internal Revenue Service. Amended Returns and Form 1040X It shows three stages:
- Received, meaning the return is in the system (usually about three weeks after mailing).
- Adjusted, meaning the IRS is reviewing and processing the changes. This is the longest stage.
- Completed, meaning processing is done and any refund or bill has been issued.
A phone line is available at 866-464-2050, but hold off calling unless the 16-week window has passed or the online tool specifically directs you to contact the IRS. Phone agents see the same status information you see online.
