Did you know?
It’s easy to make a correction to your income tax and benefit return if you realize you made a mistake after filing.
Changing your return
You will need to wait to receive your notice of assessment from the Canada Revenue Agency (CRA) before you can make a change to your return.
Once you receive your notice of assessment, you can:
- use the Change my return option found in My Account, one of the CRA’s secure online services;
- send a completed T1 Adjustment Request form (T1-ADJ) to your tax centre; or
- send a signed letter to your tax centre asking for an adjustment to your return.
If you send a letter, be sure to give your name, address, and social insurance number and tell us which tax year you want to adjust. You will also need to provide any supporting documents for your change. For example, if you want to change the amount you claimed for charitable donations, you have to submit all your charitable donation receipts to support your claim.
