NOA (Notice of Assessment)


After you file your T1 return, the CRA sends a Notice of Assessment confirming the details — your total income, deductions, tax credits, and resulting tax payable or refund. The NOA also reports your current RRSP contribution room and any carry-forward amounts.

The NOA is an important document: you need it to verify your RRSP room, apply for a mortgage (lenders often request it), and resolve any discrepancies with the CRA. If the CRA has adjusted your return (for example, disallowing a deduction), the changes will appear on the NOA with an explanation.

You can access your NOA online through CRA My Account, usually within 2 weeks of e-filing. If you disagree with an assessment, you have the right to file a formal objection within 90 days. Keep your NOAs for at least 6 years, as the CRA can reassess returns within that period.
