Need to make a change to your return?

Did you know?

It's easy to correct your income tax and benefit return if you realize after filing your return that you made a mistake.

Important facts

You will have to wait to receive your notice of assessment from the Canada Revenue Agency (CRA) before you can make a change to your return.

There are three ways to correct your return once you've received your notice of assessment:

use the change my return option found in My Account at www.cra.gc.ca/myaccount, one of the CRA's secure online services;
send a completed Form T1-ADJ, T1 Adjustment Request, 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, make 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.
