Notice of Assessment Canada (2026): What It Is, How to Read It, and What to Do Next

You filed your taxes. A few days or weeks later, a notification arrives — either a document in your CRA My Account or a letter in the mail. It says "Notice of Assessment" across the top.

Most Canadians glance at the refund or balance number, then file it away or throw it out. That is a mistake. Your Notice of Assessment is one of the most important financial documents the Canadian government produces for you — and understanding what is on it affects your tax planning, your mortgage applications, your benefit payments, and your ability to dispute the CRA's decisions.

This guide explains everything about the Canadian Notice of Assessment in 2026: what it is, what every section means, when to expect it, how to get a copy if you lost it, and exactly what to do if the numbers do not match what you filed.

Quick Answer: A Notice of Assessment (NOA) is the official document the Canada Revenue Agency sends you after processing your income tax return. It confirms your final tax result — refund, balance owing, or zero — and includes your RRSP contribution room, carryforward amounts, and an explanation of any changes the CRA made. Since February 9, 2026, NOAs are only available digitally through CRA My Account. Every Canadian who files a tax return receives one.

What Is a Notice of Assessment?

A Notice of Assessment — abbreviated as NOA — is the Canada Revenue Agency's official response to your income tax return. It is issued after the CRA processes and assesses your filing, and it serves as the government's formal confirmation of your tax position for that year.

Think of it as two things at once:

• A receipt: Proof that the CRA received, processed, and assessed your return
• A verdict: The CRA's official calculation of what you owe or are owed — which may or may not match what your tax software estimated

Every Canadian who files an income tax return receives a Notice of Assessment — regardless of income level, filing method, or whether they received a refund or owed money. It is not an audit notice. It does not mean you did anything wrong. It is simply the standard result of the filing process.

NOA vs. Notice of Reassessment (NOR)

The CRA issues two types of assessment notices:

• Notice of Assessment (NOA): Issued when the CRA processes your return for the first time. Every filed return produces one.
• Notice of Reassessment (NOR): Issued only when the CRA makes changes to a return that was already assessed — following a T1 Adjustment you submitted, a review finding, or an audit. The NOR shows exactly what changed and why.

Both documents look similar and carry the same legal weight. Both start the 90-day objection clock from their respective dates.

The Biggest 2026 Change: NOAs Are Now Digital Only

Starting February 9, 2026, the CRA changed how Notices of Assessment are delivered. This is the most significant change to NOA delivery in years — and millions of Canadians are not aware of it.

What changed: NOAs and Notices of Reassessment are now available for viewing exclusively through CRA portals — specifically CRA My Account, My Business Account, and Represent a Client. Paper copies are no longer automatically mailed.

What this means for you:

• If you have CRA My Account: Your NOA appears the moment your return is processed — often within hours for simple online returns. No waiting for mail.
• If you do not have CRA My Account: You need to call the CRA at 1-800-959-8281 to request a paper copy. This takes up to 10 business days to arrive. Setting up My Account eliminates this delay permanently.
• Quebec residents: You also receive a separate provincial NOA from Revenu Québec. This is available through Mon dossier pour les citoyens (MRQ) within 14 days of an online filing or up to 28 days for a paper filing.

Critical implication: If you need your NOA urgently — for a mortgage application, a rental application, or immigration paperwork — and you do not have CRA My Account, set it up immediately. The 10-business-day wait for a paper copy can delay important financial transactions.

When Will You Get Your NOA in 2026?

The clock on these timelines starts from when the CRA receives your return — not when you submit it. For NETFILE filers, this is effectively the same day. For paper filers, Canada Post delivery time adds days before the clock even starts.

How to Read Your NOA: Every Section Explained

Your Notice of Assessment is typically two pages. Here is exactly what each part contains and why it matters.

Section 1 — Your Personal Information and Assessment Date

The top of your NOA shows your name, address, Social Insurance Number, and the date of assessment. The assessment date is the date the CRA finalized your return — not the date you filed.

This date matters for two important reasons:

• It starts the 3-year normal reassessment period — the window during which the CRA can typically reassess your return under standard rules
• It starts the 90-day clock for filing a Notice of Objection if you disagree with anything on your assessment

Write this date down or save it. Missing the objection deadline forfeits your right to dispute the assessment.

Section 2 — Account Summary (Your Bottom Line)

This is what most people look for first. The Account Summary shows your final result in one of three ways:

• CR (Credit): You are receiving a refund. The amount shown is what the CRA will deposit or mail to you.
• DR (Debit): You owe a balance. This amount must be paid by April 30 (or was due April 30 if you are reading this after that date).
• Zero balance: You and the CRA are exactly even.

This section also shows the specific line-by-line breakdown of how the CRA calculated your result: total income, deductions applied, federal and provincial taxes, tax already withheld at source, credits applied, instalment payments credited, and any amounts from previous years.

Section 3 — Explanation of Changes

This is the most important section to read carefully — and the one most people skip.

If the CRA made any changes to your return during processing, this section lists every adjustment with the specific line number, the original amount, the new amount, and the reason for the change.

Common CRA adjustments explained in this section:

• Added income: A T4, T5, or other slip the CRA had on file that was not on your return
• Added a carryforward credit: Unused tuition credits or RRSP amounts from previous years the CRA applied on your behalf — this sometimes increases your refund
• Corrected a calculation: A math error in your favour or against you
• Denied a deduction: A claim that the CRA determined did not qualify, with a brief explanation
• Applied a pending amount: A debt offset from a prior year balance or government program

Not every change is bad news. Many CRA adjustments result in a larger refund than you expected. Read this section before assuming a change hurt you.

Section 4 — RRSP Deduction Limit Statement

This is the section most Canadians ignore — and it contains one of the most financially valuable pieces of information in your entire tax return.

Your RRSP deduction limit tells you exactly how much you can contribute to your RRSP between now and the end of February of the following year without triggering an over-contribution penalty. It is calculated based on your current year earned income plus any unused room carried forward from previous years.

2026 RRSP numbers to know:

• The 2026 annual RRSP limit is 18% of 2026 earned income, up to $35,390
• Over-contributions beyond a lifetime buffer of $2,000 are penalized at 1% per month
• Your personal limit is shown on Line A of the RRSP Deduction Limit Statement on your NOA

Check this number before making any RRSP contributions. Your tax software's estimate is a starting point — the CRA's number on your NOA is definitive.

Section 5 — Carryforward Amounts

This section lists amounts you can use on future tax returns. These are easily forgotten but can represent significant tax savings in future years:

• Unused tuition and education credits from post-secondary education — transferable to certain family members or carried forward indefinitely
• Net capital losses from previous years — applicable against future capital gains
• Non-capital losses — applicable against any income in future or past years (within the applicable carry period)
• Home Buyers' Plan (HBP) repayment balance — if you withdrew from your RRSP for a home purchase
• Lifelong Learning Plan (LLP) repayment balance — if you withdrew from your RRSP for education

If you use the same tax software every year, it should import these carryforward amounts automatically. If you switch software or have a new tax preparer, share your most recent NOA with them so these amounts are not lost.

Section 6 — Your NETFILE Access Code

On the right side of your NOA is an 8-character alphanumeric access code. This code is used when you file next year's return through NETFILE-certified tax software to confirm your identity and pre-fill information from your most recent return.

The access code is optional for NETFILE filing — but without it, you cannot use your prior return data for identity confirmation. Keep it with your tax records each year.

How to Get a Copy of Your NOA

Option 1 — CRA My Account (Instant, Available 24/7)

This is the fastest and most reliable method in 2026.

1. Go to canada.ca/my-cra-account and sign in
2. Select "Tax returns" from the main menu
3. Choose "View past returns"
4. Select the tax year you need
5. Select "Notice of Assessment" to view and download as a PDF

Every NOA you have ever received is stored in My Account and can be accessed at any time. You are not limited to the current year — previous years are also available. For mortgage or immigration applications that require multiple years of NOAs, My Account is the only way to get them instantly.

Option 2 — MyCRA Mobile App

Download the free MyCRA app (iOS and Android). NOAs are viewable and downloadable directly from your phone the moment they are issued. The app sends push notifications when your NOA is ready — you do not need to keep checking manually.

Option 3 — Express NOA Through Tax Software

If you filed using NETFILE-certified software (TurboTax, Wealthsimple Tax, UFile, H&R Block), many platforms offer "Express NOA" — a service that displays your NOA directly within the software immediately after your return is processed by the CRA. Check your software's dashboard after filing.

Option 4 — By Phone (Slowest — For Those Without Online Access)

Call the CRA at 1-800-959-8281 to request that a paper copy be mailed to your address on file. Allow up to 10 business days. Have your SIN, date of birth, and information from a previous return ready for identity verification.

Why Your NOA Is More Than a Tax Document

Your Notice of Assessment is requested in many important situations beyond tax filing. This is why keeping every NOA you have ever received — indefinitely, if possible — is strongly recommended.

What to Do If Your NOA Shows Different Numbers Than You Expected

This is one of the most common post-filing questions — and the answer depends on why the numbers differ.

Step 1 — Read the Explanation of Changes Section

Before doing anything, read Section 3 of your NOA in full. Every change the CRA made is listed with the specific reason. Most adjustments are minor and either neutral or beneficial.

Step 2 — Determine What Type of Difference It Is

Your Objection Deadline

For most individuals, the objection deadline is the later of:

• 90 days from the date on your NOA, or
• One year after the tax filing deadline for that year (April 30, 2027 for your 2026 return)

In most cases, the one-year date is later and gives you more time. But do not wait — file as soon as you have your documentation ready.

How Long to Keep Your NOA

The short answer: keep every NOA you have ever received, indefinitely.

The CRA's minimum record-keeping requirement is 6 years from the end of the tax year. But NOAs are tiny digital files or compact paper documents — there is almost no cost to keeping them forever. The situations where you need an NOA from 7, 10, or even 15 years ago (mortgage disputes, legal proceedings, immigration matters) are real and they do arise.

Store your NOAs digitally:

• Download the PDF from CRA My Account for each year and save it to a dedicated folder
• Back up that folder to a cloud storage service and an external drive
• Name each file clearly: "NOA_2026_tax_year.pdf" rather than a generic name

Frequently Asked Questions

What is a Notice of Assessment in Canada?

A Notice of Assessment (NOA) is the official document the Canada Revenue Agency sends you after processing your income tax return. It confirms whether you are receiving a refund, owe a balance, or have a zero result. It also includes your RRSP deduction limit for the following year, carryforward amounts, an explanation of any changes the CRA made, and your NETFILE access code for next year's filing. Every Canadian who files a tax return receives one.

How do I get my Notice of Assessment in 2026?

Since February 9, 2026, NOAs are only available digitally through CRA My Account — they are no longer automatically mailed. Log into canada.ca/my-cra-account, go to Tax returns → View past returns, and select the tax year to view and download your NOA as a PDF. If you do not have My Account, call the CRA at 1-800-959-8281 to request a paper copy by mail (allow up to 10 business days).

When will I receive my Notice of Assessment?

For online filers (NETFILE), the CRA aims to issue your NOA within 2 weeks of filing, and simple returns are often assessed within hours. Paper filers should allow up to 12 weeks. Non-resident and emigrant returns can take up to 16 weeks. Returns selected for a pre-assessment review take longer — until the review is resolved after you respond to the CRA's document request.

What does it mean if the CRA changed something on my NOA?

The CRA adjusts returns routinely. Check the "Explanation of Changes" section for the specific reason. Common adjustments include adding a slip that was not on your return, applying carryforward credits you did not claim (which may increase your refund), or correcting a calculation. If you agree with the change, no action is needed. If you disagree and have supporting documentation, file a T1 Adjustment or Notice of Objection within the applicable deadline.

Is the Notice of Assessment the same as a tax refund?

No — they are separate. Your NOA is the CRA's official calculation of your tax result. If that result is a refund, the money is released separately after the NOA is issued. With direct deposit, refunds typically arrive within 8 business days of your NOA date. Without direct deposit, a cheque arrives by mail within 4–6 weeks.

What is the difference between a Notice of Assessment and a Notice of Reassessment?

A Notice of Assessment is issued when the CRA processes your return for the first time — every filed return produces one. A Notice of Reassessment is issued only when the CRA makes changes to a return that was already assessed — after a T1 Adjustment, a review finding, or an audit. Both documents carry the same legal weight and both start the 90-day objection clock from their respective dates.

What is the RRSP room on my Notice of Assessment?

The RRSP Deduction Limit Statement on your NOA tells you exactly how much you can contribute to your RRSP before the end of February of the following year without triggering an over-contribution penalty. It is based on your current year earned income plus any unused room from previous years. For 2026, the annual maximum is 18% of 2026 earned income up to $35,390. Always verify this number before contributing — contributing over your limit triggers a 1% per month penalty on the excess.

Why do I need my NOA for a mortgage application?

Lenders use your NOA to verify your declared income against what the government officially assessed. They specifically use Line 23600 (net income) to calculate your debt service ratios. Most lenders require the 2 most recent NOAs. Self-employed borrowers may need 2–3 years. Without your NOA, most lenders cannot complete income verification and will not approve the mortgage.

How long should I keep my Notice of Assessment?

Keep every NOA you have ever received indefinitely if possible. The CRA's minimum requirement is 6 years, but NOAs are needed for mortgage applications, immigration paperwork, legal proceedings, tax representative authorization, and benefit calculations long after that window closes. They are small digital files — storing them forever costs nothing and protects you from situations you cannot predict today.

What is the access code on my Notice of Assessment?

The 8-character access code on the right side of your NOA is used when filing next year's return through NETFILE-certified tax software. It confirms your identity with the CRA and allows pre-filling of information from your most recent return. It is optional — you can still use NETFILE without it — but without the code you cannot use your previous return data for identity confirmation. Keep it with your annual tax records.

What if I never received my Notice of Assessment?

Since February 2026, NOAs are issued digitally through CRA My Account, not by mail. If you expected a paper copy, check your My Account instead. If you do not have My Account and have not received a paper copy after the standard processing time (2 weeks for online filers, 12 weeks for paper), call the CRA at 1-800-959-8281 to check the status of your return and request a copy.

Can I use my Notice of Assessment for immigration purposes?

Yes. Immigration, Refugees and Citizenship Canada (IRCC) frequently requests NOAs as part of permanent residency, citizenship, and sponsorship applications as proof of Canadian income and tax compliance. The specific years required vary by application type. Your NOAs are available through CRA My Account for all years on file — download the relevant years as PDFs for your application package.
