Notice of Assessment
Updated November 4, 2026
After processing your return, the CRA sends a Notice of Assessment (NOA). It shows:
- Your assessed income and tax
- Your refund or balance owing
- Your RRSP deduction limit
- Other amounts, such as carryforwards
Compare it with what you filed. If it does not match, read the explanation. An assessment is not a guarantee: the CRA can generally review an individual's return for 3 years from the original assessment date, and longer in some situations.
Keep your NOA. Lenders and benefit programs often ask for it. You can view it anytime in My Account.
