A Notice of Assessment (NOA) is the annual statement the Canada Revenue Agency (CRA) issues after it processes your tax return. It confirms how much tax you owe or will be refunded, states whether the CRA made any changes to your return, and summarizes key figures (income, deductions, credits, tax paid). It also shows your RRSP deduction limit for the next year and other carry‑forward amounts.
Why the NOA matters
– Confirms the CRA’s final assessment of your tax return.
– Shows refund or balance owing and whether you are subject to audit or reassessment.
– Lists your RRSP deduction limit and unused RRSP room — essential for retirement‑savings planning.
– Starts time limits for appeals: you usually have 90 days from the NOA date to object.
What is included on a typical NOA
– Total income, taxable income and taxable benefits (as applicable)
– Amount of tax payable and tax already paid (source deductions, instalments)
– Refund amount or balance owing (with payment due date)
– Total non‑refundable federal tax credits (and provincial equivalents)
– RRSP deduction limit (contribution room) and unused contribution carry‑forward
– Any adjustments the CRA made when processing your return
– A note if your file is selected for audit or review, or if the CRA adjusted your return
How RRSP information on the NOA works (key points)
– RRSP deduction limit = 18% of your previous year’s earned income or the annual dollar maximum (whichever is lower), plus unused room carried forward from prior years, minus pension adjustment(s). Check the NOA each year for the official amount the CRA has recorded.
– You may claim RRSP contributions as a deduction in the year made or defer the deduction to a future year to reduce tax in a year with higher income.
– If your cumulative unused contributions plus current year contributions exceed the RRSP deduction limit on your NOA by more than $2,000, a penalty tax applies: 1% per month on the excess amount.
– Certain transfers (for example, some lump‑sum transfers from a non‑registered pension plan for services rendered while you were a nonresident, eligible pension income from an estate/testamentary trust, and amounts from foreign retirement arrangements such as U.S. IRAs) can be transferred or reported without reducing your RRSP deduction room. The CRA provides details on specific transfer rules.
Practical steps — how to get and use your NOA
1. How to receive/access your NOA
• Online: Sign in to CRA My Account to view or print the NOA. Authorized representatives can use Represent a Client.
• By mail: If you do not use CRA My Account, the CRA will mail a paper NOA.
• Keep a copy for your records (CRA recommends keeping tax records for at least six years).
2. How to read your NOA (quick checklist)
• Confirm personal information is correct (name, address, SIN).
• Note refund or balance owing and any payment deadlines.
• Review any adjustments the CRA made to your return and the reason for the adjustments.
• Check your RRSP deduction limit and unused contribution room.
• Look for any messages about audits, reassessments, or follow‑up actions.
3. If you agree with the NOA
• If the NOA shows a balance owing, pay by the due date to avoid interest and penalties (payment options are in My Account and on the CRA website).
• If it shows a refund, the CRA will issue it (or deposit it to your account if you have direct deposit set up).
4. If you disagree with the NOA — step‑by‑step
• Act promptly: You generally have 90 days from the NOA date to object.
• Gather supporting documents and a clear statement of why you disagree (receipts, slips, schedules).
• File a formal objection: you can object online via My Account or submit a signed objection by mail to the tax centre indicated on the NOA. (See CRA guidance on objections for how to proceed.)
• While the CRA reviews your objection, you typically won’t have to pay the disputed amount until they finish their review. Provide the requested documentation and correspond with the CRA promptly.
• If the objection is not resolved to your satisfaction, you may have further appeal options (Tax Court of Canada). Follow CRA timelines and instructions.
5. If the CRA adjusts your return after filing (reassessment)
• The CRA will send a Notice of Reassessment with details. Review it the same way as the NOA and follow the steps above if you disagree.
6. RRSP planning steps based on your NOA
• Confirm your RRSP deduction limit on the NOA before making large contributions.
• If you have unused contribution room, consider carrying forward deductions to a higher‑income year to maximize tax savings.
• Avoid exceeding your deduction limit by more than $2,000 to prevent the 1% per month penalty; monitor cumulative contributions.
• If transferring pension or retirement funds, confirm whether the transfer affects your RRSP limit (certain transfers are permitted without reducing your limit).
Simple examples
– RRSP deduction effect: If you earned $50,000 and contributed $1,000 to an RRSP and claimed it as a deduction that year, your taxable income would be $49,000.
– Carry-forward: If your RRSP deduction limit for Year 1 was $15,000 and you made no contributions that year, you can carry that $15,000 forward; in Year 2 your available room is Year 2’s limit plus the $15,000 unused amount.
What to watch for
– Timely action on reassessments and objections (90‑day objection period).
– RRSP overcontribution penalties (1% per month over amounts exceeding the $2,000 cushion).
– Keep documentation for credits, deductions and any changes the CRA made — you may need it if the CRA questions your return or you file an objection.
