Send us only one copy of your income tax return!
We just wanted to remind you not to send us two copies of your income tax return (for example, you file one copy online and mail us a paper copy) since we will then take longer to process your return.
Receipts and supporting documents
If you file your income tax return online, you do not have to mail us your receipts and other supporting documents unless we ask for them.
Amending an income tax return
To amend an income tax return (page available in French only), you do not have to file a new income return. You must:
- complete form TP-1.R-V, Request for an Adjustment to an Income Tax Return, and mail it to us with supporting documents; or
- use the Request to Change Income Tax Return Information online service in My Account for individuals. (You must meet certain conditions.)
