All you need to know about your Notice of Assessment (NOA).

1 mai 2024

If you purchased H&R Block’s Peace of Mind® Extended Service Plan or if you added Audit Protection to your tax software package, you’ll have one of our experts by your side from the moment you receive a CRA/RQ assessment, helping you through the entire process.

You’ve organized your paperwork, done all your calculations and filed your taxes on time. Many Canadians believe that the moment they file their tax return is the moment they allow themselves to stop thinking about taxes for another year. But unfortunately, that’s not always the case. In fact, a tax return, once filed, can be assessed a number of times by either the Canada Revenue Agency (CRA) or Revenu Québec to make sure it’s accurate. Before you file your papers away, make sure you’ve received your Notice of Assessment (NOA).

What’s my Notice of Assessment and why do I need it?

Whether a Tax Expert filed your taxes for you at H&R Block or if you did them yourself and filed them online, you’ll always receive an NOA from the CRA (or Revenu Québec) once they’ve finished reviewing your return. Your NOA provides a summary of the income you earned during the year, the credits and deductions you claimed, and most importantly, it will indicate how much additional tax you have to pay (if any), or your refund amount. If the government’s numbers are different from the ones you came up with when you filed, any changes that were made on their end will be explained here.

Your NOA is full of important information, and we’ve broken down everything you need to know about it before you can officially call your taxes done for the year.

When will I get my Notice of Assessment?

If you signed up for online mail through your CRA My Account, you can get your NOA delivered to you immediately after filing your return through the CRA’s Express NOA service, which is done the instant you file your return.

If you’re receiving a paper copy of your NOA, it will usually arrive 1 to 2 weeks after your return has been assessed. If you haven’t signed up for direct deposit and you’re getting a refund, your NOA will be attached to your refund cheque. Otherwise, it'll arrive separately.

If you’re a resident of Québec, you’ll receive your NOA from Revenu Québec within 2 weeks if you filed your return online, or within 28 days if you filed your return by mail. If you registered to receive your NOA online, you can access it through your Revenu Québec My Account for individuals. Otherwise, you’ll receive a paper copy of your NOA in the mail.

It looks like the CRA or Revenu Québec made changes to my return. Do I need to do anything?

Even if you double-checked all of your numbers, mistakes can happen. For example, if you forgot to claim the Canada Employment Amount, the CRA will add it to your return. If you claimed something you shouldn’t have, your NOA will show the change, and include an explanation.

The CRA and Revenu Québec don’t require any action from you when they make changes, and they’ll tell you if there are penalties or interest as a result of anything that’s changed.

The changes on my Notice of Assessment don’t make sense to me.

NOA’s are computer-generated, so they might contain standard explanations that aren’t easy to understand. You can always give the CRA (or Revenu Québec) a call to make sure you understand any changes that have been made, and agree that they are correct.

Is the date I receive my Notice of Assessment important?

The date on your NOA is used to establish the deadline for objecting to any changes the CRA (or Revenu Québec) has made. It also sets the beginning of the three-year period during which the CRA can reassess your return. After this three-year period has expired, there are a limited number of situations in which they can still reassess you, but the most important is if you committed fraud or were negligent in the preparation of your return.

This year’s Notice of Assessment can help you next year.

Your NOA is handy when preparing your next tax return, so keep it somewhere you can easily find it again. It contains your Registered Retirement Savings Plan (RRSP) contribution limit, your First-Home Savings Account (FHSA) limit, and your Tax Free Savings Account (TFSA) limit for the year. Even though you don’t report your TFSA on your income tax form, the contribution limit for the year is included in the summary report of your NOA from the CRA.

Carry forward amounts are also included on your NOA from the CRA. This includes your carried over capital losses, your unused tuition and education credits, as well as your Home Buyers’ Plan (HBP) balance and repayment information. Overall, this will be helpful information to know for next year’s return.

One cool feature that was introduced in 2020 was the NETFILE Access Code (NAC). This is an 8-character code that’s used as an added security measure to verify your identity when you file your federal return online. It can be found on the right side of your NOA from the previous tax year.

Entering your NAC isn’t mandatory; you’ll still be able to NETFILE without it. However, if you don’t enter it, you won’t be able to use any information from your previous tax return to confirm your identity with the CRA in the future (for example, if you need to call the CRA, or sign up for your CRA My Account). You’ll need to use other information to authenticate your identity.

You don’t need your NAC to file Québec returns. The NAC doesn’t apply to you if you’re filing your first tax return, and it doesn’t apply in Québec.

Where should I keep my Notice of Assessment?

Wherever you have your paperwork for safekeeping – whether that’s a tax envelope, folder or drawer, or even a whole closet – your previous year’s NOA should be filed there, because you might need it for something other than your taxes. If you’re applying for a mortgage or loan, your financial institution will probably ask for a copy of your NOA to prove income. Some social programs might also request a copy of your NOA to check your annual income for the previous year.

I lost my Notice of Assessment. What should I do?

If you’ve searched high and low but can’t seem to track down your NOA, here’s how you can get a copy from the CRA.

Log into your CRA My Account (registration required) to view and print any of your NOAs or notices of reassessment issued after February 9, 2015. For years prior to that, you’ll be able to see detailed summaries of your notice of assessment or reassessment.

The MyCRA app is now part of the mobile-friendly My Account for Individuals. Your existing credentials can be used when you sign in with My Account.

For an NOA or notice of reassessment issued by Revenu Québec, log into your My Account for individuals (registration required) to view and print a copy (back to 2004).
