If you make a mistake, you can still change your tax returns after you file your taxes. You need to refile or amend your return. You can amend your returns dating back 10 years. Wait to receive a Notice of Assessment first before making changes.

If you have used TurboTax Online, you can use the ReFILE option by signing in to your account, and on the side of the NETFILE return, you will have a ReFILE button. In TurboTax Online, ReFile is not available for Quebec residents.

If you're using TurboTax Desktop, when you open your 2024 software, you click on “Change a filed return," choose the return you want to modify, click on "Modify return" (in the NETFILE section), and follow the steps to apply the changes and ReFILE. If the steps are done in this order, the ReFILE button will be there.

In all cases, regardless of the software version used, you can do so directly in your CRA My Account or by mail by completing the following forms:
