How to Read Your Notice of Assessment from CRA (2026 Guide)
What every section of your NOA actually means, what changed with CRA's February 2026 delivery update, and what to do if the numbers don't match what you filed.
1. What Is a Notice of Assessment?
A Notice of Assessment (NOA) is the official document the Canada Revenue Agency issues after processing your income tax return. It confirms the income you reported, the deductions and credits applied, and your final result — whether you owe a balance, are receiving a refund, or are exactly even. Every person and business that files a return receives one; it's a standard part of the process, not a sign that something has gone wrong.
The NOA also does double duty as a reference document. Lenders and mortgage brokers frequently ask for it as proof of income, and it's the source most Canadians use to check their RRSP contribution room for the following year.
For business owners, understanding your personal NOA is just as important as understanding your corporate tax filings, which is why this often overlaps with core accounting and tax compliance services rather than being treated as a separate, one-off document.

2. What Changed for NOAs in 2026
Starting February 9, 2026, the CRA changed how Notices of Assessment and Reassessment are delivered. They are now available primarily through CRA's online portals — My Account, My Business Account, and Represent a Client — rather than being automatically mailed as a paper copy to everyone. If you have a CRA account, your NOA typically appears there as soon as your return is processed, often within hours for straightforward returns, and the CRA sends an email notification when it's ready to view.
- If you have CRA My Account: Your NOA appears online as soon as processing completes — no need to wait for mail.
- If you don't have an account or prefer paper: The CRA continues mailing a paper copy to the address on file, though this may require registering or requesting it directly.
- Express NOA: Some NETFILE-certified software shows an instant summary right after filing, but this is not your official NOA and isn't accepted by lenders for mortgage or loan applications.
- Quebec residents: A separate provincial NOA is issued by Revenu Québec through the Mon dossier portal.
3. The Sections of Your NOA Explained
| Section | What It Shows |
|---|---|
| Header information | Your name, address, Social Insurance Number, and the assessment date |
| Account summary | Your final result: refund (CR), balance owing (DR), or zero balance |
| Explanation of changes | Line-by-line detail of anything the CRA adjusted from what you filed |
| RRSP/PRPP deduction limit | Your available RRSP contribution room for the following year |
| Statement of account | Any outstanding balances, interest charges, or amounts from prior years |
The assessment date at the top of the document matters more than it looks. It starts two important clocks: the 90-day window to file a formal objection if you disagree with anything, and the 3-year normal reassessment period during which the CRA can generally reopen and reassess your return.
4. Reading the Account Summary: CR, DR, or Zero
- CR (Credit): You're receiving a refund — the amount shown is what the CRA will deposit or mail to you.
- DR (Debit): You owe a balance to the CRA, which should be paid by the deadline to avoid interest.
- Zero balance: You and the CRA are even; nothing further is owed and no refund is issued.
Compare this figure directly against what you expected when you filed. If it doesn't match, the "Explanation of Changes" section will show exactly what the CRA adjusted and why — sometimes changes actually work in your favour, such as when the CRA applies a carryforward credit you weren't aware of.

5. Your RRSP/PRPP Deduction Limit Explained
Your RRSP Deduction Limit Statement shows how much you can contribute and deduct for the following tax year. It's calculated as 18% of your prior year's earned income, up to an annual dollar cap, plus any unused contribution room carried forward from previous years, minus any pension adjustments reported by your employer.
| Figure | 2026 Amount |
|---|---|
| RRSP annual dollar limit | $33,810 |
| TFSA annual contribution limit | $7,000 |
| Cumulative TFSA room (eligible since 2009) | $109,000 |
| RRSP over-contribution buffer (before penalty) | $2,000 lifetime |
Figures reflect CRA-published limits for the 2026 tax year and are subject to change. Always confirm your personal deduction limit on your latest NOA or in CRA My Account.
6. TFSA Contribution Room and Other Figures
Unlike your RRSP room, TFSA contribution room isn't shown on your Notice of Assessment — it's tracked separately and available through CRA My Account, though the CRA notes this figure depends on financial institutions reporting contributions accurately and may not update until later in the year. Your NOA may also reference Home Buyers' Plan (HBP) or Lifelong Learning Plan (LLP) repayment obligations if applicable, shown in collapsible sections in the online version.

7. What to Do If the CRA Changed Your Return
- Read the "Explanation of Changes" section carefully — it details exactly what was adjusted and why
- Compare each changed line item against your original filed return
- If you agree with the change, no further action is needed
- If you disagree, you have two main options depending on the situation: a T1 Adjustment or a formal Notice of Objection
A Notice of Reassessment (NOR) works the same way as an NOA but is issued when the CRA later reviews and changes a previously assessed return — the same 90-day objection deadline applies to reassessments as well.
8. What to Do If You Disagree: Adjustments vs. Objections
| Situation | T1 Adjustment | Notice of Objection |
|---|---|---|
| Purpose | Correct a missed deduction, slip, or reporting error | Formally dispute a CRA decision you disagree with |
| Time limit | Generally up to 10 years after original filing | 90 days from assessment date, or 1 year after filing deadline, whichever is later |
| How to file | CRA My Account or Form T1-ADJ | CRA My Account ("Register a formal dispute") or Form T400A |
| Best for | Simple corrections, missed slips or credits | Disputing CRA's interpretation or assessment of a specific issue |
File an objection even if you don't yet have every supporting document ready — you can supplement it later, but missing the deadline generally requires a separate, discretionary application for an extension.
9. For Business Owners: Corporate Assessments Work Differently
Incorporated businesses receive a similar assessment for their corporate tax return (T2), alongside their owners' personal NOAs for salary, dividends, or other income drawn from the business. Keeping clean, well-organized books throughout the year makes both assessments faster to review and easier to reconcile if the CRA adjusts anything.
- Accurate bookkeeping software setup reduces the chance of reporting errors that lead to reassessments
- Consistent payroll compliance and remittance tracking avoids surprises tied to source deductions
- Industries with more complex cost tracking, such as those covered in our guides on bookkeeping for consumer goods manufacturers and bookkeeping for waste management companies, benefit even more from clean records when reviewing assessments
- Reviewing our top 5 tax mistakes Canadian businesses make can help you avoid the errors most likely to trigger a reassessment in the first place
Custom CPA supports both personal and corporate tax compliance, including specialized reporting services and business planning and financial modeling, so your assessments consistently reflect what you actually expect to see.
10. Frequently Asked Questions
What is a Notice of Assessment and why did I receive one?
A Notice of Assessment (NOA) is the CRA's official summary of your tax return after it has been processed, confirming your reported income, credits, deductions, and final balance. Every person or business that files a return receives one automatically — it is not an audit notice and does not mean anything is wrong.
How long does it take to get my Notice of Assessment in 2026?
If you filed online through NETFILE or EFILE, your NOA is typically available in CRA My Account within about two weeks, and often within hours for simple returns processed after the CRA's February 2026 digital delivery update. Paper-filed returns generally take six to eight weeks or longer, especially during peak filing season.
What is the difference between a Notice of Assessment and a Notice of Reassessment?
A Notice of Assessment (NOA) is issued after your original return is processed, while a Notice of Reassessment (NOR) is issued if the CRA later reviews and changes a previously assessed return, whether due to new information, a filed adjustment, or a CRA-initiated review. The same 90-day objection deadline applies to both documents.
How do I dispute or correct my Notice of Assessment if I disagree with it?
If you simply missed a deduction or made an error, you can file a T1 Adjustment request, which is generally accepted for up to 10 years after the original filing. If you disagree with a decision the CRA made on your assessment, you can file a formal Notice of Objection using Form T400A or through CRA My Account within 90 days of the assessment date, or one year after your filing deadline, whichever is later.
Where do I find my RRSP contribution room on my Notice of Assessment?
Your RRSP/PRPP Deduction Limit Statement appears near the bottom of your Notice of Assessment and shows your available contribution room for the following year. It is calculated as 18% of your prior year's earned income, up to the annual dollar limit of $33,810 for 2026, plus any unused room carried forward, minus any pension adjustments.
11. Final Thoughts
Your Notice of Assessment is more than a receipt for filing your taxes — it confirms your CRA balance, tracks your RRSP room, and starts the clock on important deadlines like your objection window and reassessment period. With CRA's move to online-first delivery in February 2026, checking your CRA My Account regularly is now more important than waiting on the mail. Understanding each section, and knowing whether a T1 Adjustment or a formal objection applies to your situation, puts you in a much stronger position if anything on your assessment doesn't look right.
