Filing your income tax and benefit return each year is what you need to do to receive any benefit and credit payments you’re entitled to. Sometimes after you file, you realize you made a mistake or forgot to include something important. If this happens to you, don’t worry. It’s easy to change your tax return.
If you need to change your tax return, you can do so after filing. Once you have your notice of assessment (NOA), you can make a change. For faster service, submit your change request online.
