The easiest way to get your T1 is online. If you have a CRA My Account, you can find your T1 for the current year, as well as the past 11 years that you filed, by looking under the “tax returns view” section. If you look for anything older, you will need to contact the CRA directly at 1-800-959-8281 to request a copy.
Can I do T1 Adjustment online?
Individuals can change their T1 return online for the 2020, 2019, 2018, and 2017 tax years with certified NETFILE software. After you have made online changes to your tax return, keep all your receipts and supporting documents in case the CRA asks to see them.
Can you file amended tax return online?
Can I file my Amended Return electronically? If you need to amend your 2019 or 2020 Forms 1040 or 1040-SR you can now file the Form 1040-X, Amended U.S. Individual Income Tax Return electronically using available tax software products.
What is the difference between T1 General and Notice of Assessment?
Your NOA can be found under the “tax returns” tab. A T1 General is your tax return. The person who submits your tax return should provide you with a copy of your T1 General as soon as your return is complete. If you file your own taxes through software such as TurboTax or UFile, you can find your T1 General there.
How far back can you file a T1 Adjustment?
You are able to ask for an adjustment to be made to a tax year ending in any of the 10 previous calendar years. For example in 2016, you can adjust tax returns dating back to 2006. Once you have sent in your T1 Adjustment, CRA has processing times up to 8 weeks before a Notice of Reassessment is issued.
