How to amend (change or correct) a return you already filed

You can amend e-filed returns if they've been accepted; paper-filed returns may be amended once they've been mailed.

If your e-file is still pending, you won't be able to make changes until the IRS either accepts or rejects it. Don't know your e-file status? Here's how to look it up.

Select your tax year for amending instructions:

2019
2018
2017
2016

Keep in mind: You have 3 years from the date you filed your return or 2 years after you paid the tax due (whichever is later) to file an amendment.
