How to Sign a 1040-X Form Easily

Form 1040-X is meant for taxpayers to amend taxes they have erroneously returned. After filling the return, you don’t have (and, generally speaking, you can’t) just refile taxes. But mistakes and errors do happen, so there is a special form 1040-X you need to fill, sign, and file.

If you were wise enough to keep a copy of your return, you could review it later when you discovered a mistake or found a reason to claim tax credit or deduction. It can be filed after you have filed your main forms.

If you still have some questions left, here are the most common ones taxpayers usually ask about signing a 1040-X Form. Read them thoroughly to understand the specifics.

What is an amended tax return?

It’s the amendment to your tax returns you have already filed but want to amend. The reasons may vary: you might have found a mistake in your returns or remembered some income you had not mentioned, or learned a reason to file for tax credits or deductions.

Who can sign an amended tax return?

Spouses can sign for each other under certain circumstances (if the return is joint, though, both spouses must sign it). Parents can sign for their minors in case their signatures are necessary, too. In general, the returns can be signed by third parties that have the power of attorney, and a form confirming the power needs to be included.

Can I e-sign Form 1040-X?

Yes, and the guide above contains an explanation of how to do it.

Can someone else amend my tax return?

Tax amendment forms are meant to be sent by the taxpayers whose returns are amended. But someone else empowered to do so (like paid preparers) can help this person to do the work.
