topic 1040x in After you file

1040x

StauffR — Tue, 10 Feb 2026 10:18:22 GMT

Hi... I discovered that the 1040x I sent in was unnecessary and that my original 1040 sent in was correct. Can I negate the 1040x somehow?

Not exactly.

If you mailed or e-filed an amended tax return, and the IRS processes it and doesn't object or send a letter asking for more information, then that has become your new official tax return for that year. To change it, you would have to file a second amended tax return that changes your information back to the original.

If IRS can see your error on 1040-X, it will be REJECTED, and that's that.

IRS will respond with the status of your amendment.

I was avoiding the use of the term "rejected." If you e-filed the 1040x, it was accepted into the IRS system if the basic info matched (income, social security numbers, birthdates). It would be "rejected" electronically if the basic info didn't match. However, that doesn't mean the IRS agrees or disagrees with the changes. It takes 4-6 months for the IRS to review an amended return. If they agree with the amended return, they will pay a refund if you requested one. If you did not request a refund, you might not get any notification that they agree with your amended return. If they disagree with your amended return, they will probably send you a letter.

If you get a letter of the IRS refusing you amended return or asking for more information, you can respond by saying you made a mistake and asking them to cancel or withdraw the amended return. But if they accept the amended return and pay your additional refund, then you would have to file a second amended return.
