How Far Back Can You Amend Taxes?

Mistakes happen, and when they do, it’s important to know how to correct them. If you’ve made a mistake on your tax return, you can amend it by filing Form 1040X. But how far back can you amend your taxes?

The IRS allows you to amend your tax return for up to three years from the date you filed the original return, or within two years from the date you paid the tax, whichever is later.

For example, if you filed your 2020 tax return on April 15, 2021, you have until April 15, 2024, to file an amended return. However, if you paid your 2020 taxes on October 15, 2021, you have until October 15, 2023, to file an amended return.

It’s important to note that you can only amend a tax return that has already been filed. If you haven’t filed your tax return yet, you can simply make the corrections on the original return.
