Is it possible to amend a tax return after it has been filed ?

Yes, you can amend your tax return after filing if you realize there are errors or if you need to make changes to the information you initially reported. This is done by submitting a T1 Adjustment Request form to the Canada Revenue Agency, depending on the nature of the changes needed. It's important to ensure accuracy and completeness when amending your tax return to avoid potential issues or delays in processing.
