If you have a CRA Account and use certified tax software, you can use Auto-fill My Return to automatically import the tax information the CRA has on file at the time of the request.
Before you use Auto-fill My Return, make sure you received all your slips and they appear in My Account. Otherwise, any slips that may be missing won’t auto-populate when you use the service.
When you’re ready:
1) Launch Auto-fill My Return from your certified tax software
2) Sign into your CRA Account
3) Your available slips and information (including your NETFILE access code) will be securely sent to your software
4) You can choose which slips and information to auto-populate your return
5) Review everything carefully before filing
If a slip isn’t available yet from Auto-fill My Return, you have to manually enter the information using the slip received from the issuer.
