CRA Notice of Assessment Explained (2026): What It Is and How to Read It

You filed your taxes. A few days or weeks later, a document arrives from the Canada Revenue Agency. It is called a Notice of Assessment — and most Canadians stare at it, unsure of what they are actually looking at.

This guide explains everything in plain language: what the NOA is, what every section means, when to expect it, what changed in 2026, and what to do if the CRA got something wrong.

Quick Answer: A Notice of Assessment (NOA) is the official document the CRA sends you after processing your tax return. It confirms whether you are getting a refund, owe money, or are at zero. It also shows your updated RRSP room for next year. It is not an audit notice — every Canadian who files gets one.

What Is a Notice of Assessment?

A Notice of Assessment — often called an NOA — is the CRA's official summary of your income tax return after they have reviewed and processed it. Think of it as the CRA's report card on your filing.

It tells you three things above all else:

• Whether the CRA agrees with what you filed
• Whether you are getting a refund, owe a balance, or are at zero
• How much RRSP room you have for next year

This is not an audit notice. The CRA sends a Notice of Assessment to every single Canadian who files a tax return — it is completely routine. Receiving one does not mean you did anything wrong.

The NOA is also one of the most useful financial documents you own. Banks ask for it when you apply for a mortgage. Immigration Canada uses it as proof of income. Benefits programs reference it to calculate your eligibility. Keep it safe.

Big Change in 2026: How You Receive Your NOA

Starting February 9, 2026, the CRA made a significant change to how Notices of Assessment are delivered.

Notices of assessment and reassessment are now available for viewing exclusively through CRA portals — specifically CRA My Account, My Business Account, and Represent a Client. The moment the CRA processes your return, your NOA appears in your online account.

What this means for you:

• If you have CRA My Account: Your NOA is there as soon as your return is processed — often within minutes for simple online returns.
• If you do not have CRA My Account or prefer paper: The CRA will still mail a paper copy to your address on file. Set up your account at canada.ca to get it faster.
• Quebec residents: You also receive a separate NOA from Revenu Québec, available through your Mon dossier pour les citoyens (MRQ) account.

Bottom line: Set up CRA My Account if you have not already. It is free, takes about 10 minutes, and means you get your NOA — and your refund — as fast as possible.

When Will You Get Your NOA in 2026?

The timing depends entirely on how you filed your return.

If your return was selected for a more detailed review, processing will take longer. The CRA will contact you if they need more information before issuing your NOA.

How to Read Your NOA: Every Section Explained

Your Notice of Assessment is typically two pages. Here is what each section means in plain language.

Section 1 — Your Name, SIN, and Assessment Date

The top of your NOA shows your name, address, Social Insurance Number, and the date of assessment. That date is more important than it looks — it starts the 90-day clock for filing a formal objection if you disagree with anything. Write it down.

Section 2 — Tax Assessment Summary

This is the main result. It shows your final balance in one of three ways:

• CR (Credit): You are getting a refund. The CRA owes you money.
• DR (Debit): You owe a balance. You need to pay the CRA.
• Zero balance: You and the CRA are even.

This section also shows:

• Your total income as assessed by the CRA
• Federal and provincial taxes calculated
• Credits and deductions applied
• Any instalment payments you made during the year
• Amounts carried over from a previous year
• CPP contributions assessed

Compare these numbers directly to what you filed. If anything differs, look at the next section.

Section 3 — Explanation of Changes

If the CRA changed anything on your return — even something small — this section explains exactly what was changed and why, line by line.

Common CRA adjustments include:

• Adding income from a T4 or T5 slip the CRA has on file that you did not report
• Correcting a math error
• Adding a tuition carryforward credit you forgot to claim from a previous year
• Disallowing a deduction that does not qualify
• Adjusting a credit based on updated slip information

Sometimes CRA changes actually increase your refund — for example, when they add a carryforward credit you were not aware of. Read this section carefully before assuming a change is bad news.

Section 4 — RRSP Deduction Limit Statement

This is one of the most valuable parts of your NOA — and the one most Canadians ignore.

Your RRSP deduction limit tells you exactly how much you can contribute to your RRSP before the end of February next year without triggering an over-contribution penalty (which is 1% per month on the excess amount). This figure is calculated based on your earned income from the current year and any unused room carried forward from previous years.

Check this number every year. It is the foundation of smart RRSP planning and it only exists in your NOA.

Section 5 — Carryforward Amounts

This section lists amounts you can use on future tax returns, including:

• Unused tuition credits from post-secondary education
• Net capital losses from previous years you can apply against future capital gains
• Non-capital losses available for future years
• Home Buyers' Plan (HBP) repayment schedule if applicable

These amounts are easy to forget — but they can save you significant money in future years. Your tax software should pull them in automatically if you use the same software, but always verify.

Section 6 — Your Access Code

On the right side of your NOA you will find an 8-character access code made up of numbers and letters. This code is used when you file next year's return through NETFILE software.

While the code is not mandatory to use NETFILE, without it you will not be able to use information from your most recent return to confirm your identity with the CRA. Keep it somewhere safe with your tax records.

NOA vs. Notice of Reassessment: What Is the Difference?

Many Canadians confuse these two documents. Here is the key difference:

Receiving a Notice of Reassessment months or years after filing is not unusual — and it is not automatically bad news. Sometimes the CRA reassesses to add a carryforward credit or to correct a minor discrepancy. Read the explanation of changes section to understand what was updated.

Where Your NOA Gets Used Outside of Tax Season

Your Notice of Assessment is not just a tax document — it is one of the most widely requested financial documents in Canada. You may need it for:

• Mortgage applications: Lenders use your NOA to verify your stated income. Most banks want to see the last 2 years.
• Rental applications: Landlords often request an NOA as income proof.
• Immigration and permanent residency applications: IRCC may request your NOA to demonstrate financial stability in Canada.
• Government benefit programs: Programs like the Canada Child Benefit and provincial assistance programs calculate eligibility based on the income shown on your NOA.
• OSAP and student financial aid: Post-secondary financial aid applications typically require your NOA.
• Calling the CRA: When you call the CRA, agents use your NOA information to verify your identity.

This is why it is worth keeping every NOA you have ever received — not just the current year's.

How to Get a Copy of Your NOA

If you need your NOA and cannot find it, here are your options:

• CRA My Account (fastest): Log in at canada.ca/my-cra-account and navigate to "Tax returns." Your NOA for every year you have filed is stored there and can be viewed and printed instantly.
• Through your tax software: If you use NETFILE-certified software (TurboTax, Wealthsimple Tax, H&R Block), your NOA is often available directly in the app once it is issued.
• By phone: Call the CRA at 1-800-959-8281 and request a paper copy. Have your SIN, date of birth, and total income from a previous return ready to confirm your identity.

What to Do If Your NOA Is Wrong

First: do not panic. CRA adjustments are common and often minor. Here is how to handle a discrepancy.

Step 1 — Compare the NOA to Your Filed Return

Go line by line through the assessment summary and compare it to your original T1 return. Check the explanation of changes section to understand what the CRA modified and why.

Step 2 — Decide: Mistake or Disagreement?

There is a difference between a mistake you made and a CRA decision you disagree with.

• If you made an error (forgot a deduction, missed a slip, made a math mistake): File a T1 Adjustment through CRA My Account or by mail. Wait until you receive your NOA before submitting any adjustment.
• If you disagree with the CRA's decision (they denied a legitimate deduction, changed your income incorrectly): File a formal Notice of Objection.

Step 3 — Know Your Deadline

If you want to formally dispute your assessment, you must act within a specific window. You have until the later of these two dates:

• One year after the tax filing deadline for that year
• 90 days from the date on your NOA

For most Canadians filing on time, this means you have until about July 30 following the April 30 deadline. Do not miss it — if you do, you must apply for an extension and explain why you could not act in time. Extensions are granted at the CRA's discretion.

Step 4 — File a Notice of Objection

File your Notice of Objection through CRA My Account (fastest) or by completing Form T400A and mailing it to your CRA tax centre. Include all supporting documentation. The CRA's Appeals Division will review your case independently of the original assessor.

If the Appeals Division rules against you, you can escalate to the Tax Court of Canada. At that point, having a tax lawyer or CPA on your side is strongly recommended.

NOA and the Mortgage Application: What Banks Actually Need

This is one of the most common reasons people suddenly need to track down an old NOA. Here is what Canadian lenders typically require:

• Most banks want 2 consecutive years of NOAs
• For self-employed borrowers, lenders typically want 2 years and may also request T1 Generals and financial statements
• Some lenders accept a Statement of Account from CRA My Account as an alternative if the NOA is unavailable
• The NOA must show your net income — the amount on Line 23600 of your return — which is what most lenders use for qualification purposes

If you are planning to apply for a mortgage in the next year or two, make sure you file your taxes on time and keep your NOAs accessible. Lenders cannot move forward without them.

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 getting a refund, owe money, or have a zero balance. It also shows your RRSP contribution room for the following year and any carryforward amounts. Every Canadian who files a tax return receives one.

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

No — they are separate. Your NOA confirms the result of your return assessment. If that result is a refund, the CRA then issues your refund separately. For online filers with direct deposit, refunds typically arrive within 8 business days of the NOA being issued.

How long does it take to get a Notice of Assessment in 2026?

For online filers (NETFILE), the CRA aims to issue your NOA within 2 weeks, and for simple returns it can happen within hours. Paper filers should allow up to 12 weeks. Since February 9, 2026, your NOA is available in CRA My Account the moment it is issued.

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

It means the CRA adjusted one or more items when processing your return. This is common and not necessarily bad — sometimes it increases your refund. Read the "Explanation of Changes" section to see exactly what was modified and why. If you agree with the change, no action is needed. If you disagree, you can file a T1 Adjustment or a formal Notice of Objection.

How do I get a copy of my Notice of Assessment?

The fastest way is through CRA My Account at canada.ca — every NOA you have ever received is stored there and can be printed instantly. You can also call the CRA at 1-800-959-8281 to request a paper copy, or access it through your NETFILE tax software if you used one.

What is the RRSP room on my NOA?

The RRSP deduction limit 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 a penalty. It is based on your earned income and any unused room from previous years. Always check this number before making RRSP contributions.

What is the access code on my NOA?

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 is optional but using it lets you pre-fill your return with information from the previous year and confirms your identity with the CRA more easily.

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

A Notice of Assessment is issued when the CRA first processes your return. A Notice of Reassessment is issued when the CRA revises a return that was already assessed — for example, after a T1 Adjustment, a review, or a CRA audit. Both documents look similar and carry the same 90-day objection deadline.

I disagree with my NOA. What can I do?

You have two options. If you made an error on your return, file a T1 Adjustment through CRA My Account. If you believe the CRA made an error, file a formal Notice of Objection within 90 days of your assessment date (or one year after the filing deadline, whichever is later). Include all supporting documentation.

Do I need my NOA for a mortgage application?

Yes — most Canadian lenders require 2 consecutive years of NOAs to verify your income when applying for a mortgage. For self-employed borrowers, lenders typically also request T1 General returns and may ask for business financial statements. Keep your NOAs accessible and file your taxes on time if a mortgage application is in your future.

How long should I keep my Notice of Assessment?

Keep every NOA you have received indefinitely if possible. The CRA's standard record-keeping requirement is 6 years, but NOAs are compact, easy to store digitally, and come in handy for mortgage applications, immigration paperwork, benefit calculations, and CRA identity verification long after the 6-year window closes.

Is a Notice of Assessment the same as a Notice of Reassessment?

No. An NOA is issued after the CRA first processes your return. A Notice of Reassessment (NOR) is issued when the CRA goes back and changes a return that was already assessed. Both look similar and carry the same 90-day window to file a formal objection from the date on the notice.
