Have you filed your taxes already? If you have not—or if the IRS rejected your e-file—then you can fix whatever you need to before transmitting.
If you filed your return and the IRS has accepted your return, then you will have to prepare and send an amended tax return.
How to amend (change or correct) a return you already filed
You may have to amend your state taxes as well.
Wait until you receive your refund before amending your return. The IRS may catch some of your mistakes and adjust your refund.
You can check the status of your paper or electronically-filed amended return using the Where's My Amended Return? (WMAR) online tool or the toll-free telephone number 866-464-2050 three weeks after you file your amended return. Both tools are available in English and Spanish and track the status of amended returns for the current year and up to three prior years.
