What Happens After You File Your Taxes in Canada: Complete Guide (2026)

You clicked submit — or dropped that envelope in the mail. Your Canadian tax return is done. Now what?

For most Canadians, the post-filing period is straightforward. But knowing exactly what to expect, step by step, helps you avoid surprises, respond to the CRA on time, and make the most of your refund or manage a balance owing. This guide walks you through everything that happens after you file your taxes in Canada — from the moment the CRA receives your return to what you should be doing a year from now.

Quick Answer: After filing your Canadian tax return, the CRA processes it and sends you a Notice of Assessment (NOA). If you are owed a refund, it typically arrives within 2 weeks for online filers with direct deposit. If you owe a balance, it must be paid by April 30 to avoid interest. You can amend your return, respond to a review, or file an objection if needed. You must keep your tax records for 6 years.

1. The CRA Receives and Processes Your Return

Once you file your income tax return, the Canada Revenue Agency (CRA) begins processing it. What happens behind the scenes depends on how you filed:

• Online via NETFILE: The CRA receives your return in real time. Processing typically begins within hours.
• Paper return by mail: The CRA receives your return days or weeks after you mail it. Processing takes considerably longer.

During processing, the CRA verifies your identity, cross-references your reported income against T4s, T4As, and other slips they have on file, confirms eligible deductions and credits, and calculates your final tax result.

Standard CRA processing times:

You can monitor the progress of your return using the CRA Progress Tracker in your CRA My Account. This digital tool shows you exactly where your return is in the processing pipeline — similar to tracking a package delivery.

2. Your Notice of Assessment (NOA) Explained

The Notice of Assessment (NOA) is the most important document you will receive after filing your taxes. It is the CRA's official confirmation that your return has been received, reviewed, and assessed.

Think of it as your annual tax report card from the federal government. It confirms your filing details, shows your final tax result, and provides critical information you will need for loans, mortgage applications, benefit claims, and future tax planning.

What is in Your NOA?

• Account Summary: Shows whether you have a refund, a balance owing, or a zero balance.
• Assessment Details: A summary of all line numbers and amounts the CRA used — including any changes they made to your return.
• Explanation of Changes: If the CRA adjusted anything on your return, this section explains what was changed and why.
• RRSP Contribution Room: Your updated Registered Retirement Savings Plan deduction limit for the upcoming year — extremely useful for tax planning.
• Carryforward Amounts: Any unused tuition credits, capital losses, or other amounts you can apply to future returns.
• Access Code: An 8-character code used when filing next year's return via NETFILE. Keep it somewhere safe.

NOA vs. Notice of Reassessment (NOR)

The CRA sends a Notice of Reassessment (NOR) only when they make changes to your already-assessed return. This can happen months or even years after your original filing. A NOR is not a penalty or an audit notice — it is simply an updated summary of the changes made.

How to Get Your NOA

• Online (fastest): Available in CRA My Account within approximately 2 weeks of filing electronically.
• Through your tax software: Most NETFILE-certified platforms (TurboTax, Wealthsimple Tax, H&R Block) connect to CRA systems and notify you when your NOA is ready.
• By mail: Paper copies are mailed if that is your preferred delivery method or if you have not provided an email address to the CRA.

Important: If your NOA does not match what you filed, read the explanation section carefully before taking any action. The CRA sometimes adds previously unclaimed tuition carryforward amounts or makes corrections based on slips they have on file — changes that may actually increase your refund.

3. If You Are Getting a Tax Refund

Canada issued more than 19 million tax refunds in the most recent tax-filing season, with an average refund of $2,294. If you are in that group, here is what you need to know.

How Fast Will You Get Your Refund?

The speed of your refund depends on two things: how you filed and whether you have direct deposit set up with the CRA.

• Online filing + direct deposit: Refund typically arrives within 8 business days after your NOA is issued.
• Online filing + cheque: Allow up to 8 weeks for the cheque to arrive by mail.
• Paper return: Refunds can take 8 weeks or longer after the CRA processes your paper return.

The refund clock starts from your assessment date — not the date you submitted your return. There is often a short processing gap between submission and when the CRA officially assesses your return.

Set Up Direct Deposit — Today

If you have not already, setting up direct deposit through CRA My Account is one of the simplest financial decisions you can make. It is faster, more secure, and eliminates the risk of a refund cheque getting lost or delayed in the mail. You can set it up at any time through your bank or through your CRA My Account.

Why Is My Refund Delayed?

A few common reasons the CRA may hold or delay a refund:

• Your return was selected for a more detailed review
• You have an outstanding balance on another CRA account (income tax, GST/HST, student loans, EI overpayment)
• You have unfiled returns from previous years
• There is a discrepancy between your return and the slips the CRA has on file
• You are a non-resident or emigrant — these returns take up to 16 weeks

If it has been more than 8 weeks since you filed online and you still have not received your refund, contact the CRA at 1-800-959-8281 or check your status through CRA My Account.

What to Do With Your Tax Refund

If you are deciding what to do with your tax refund, remember that it is not a bonus — it is your own money the government held through the year. Some smart ways Canadians put their refund to work:

• Contribute to your RRSP — reduces next year's tax bill
• Max out your TFSA — grows tax-free forever
• Pay down high-interest debt (credit cards, lines of credit)
• Build or top up your emergency fund
• Make a lump-sum mortgage payment if your terms allow it

4. If You Owe a Balance to the CRA

If your NOA shows a balance owing, do not panic — but do act quickly. Here is what you need to know.

The Payment Deadline Is April 30

Regardless of your filing deadline, any balance owing must be paid by April 30 to avoid interest charges. This is one of the most misunderstood rules in Canadian tax:

• Most individuals: File and pay by April 30
• Self-employed individuals: Can file until June 15, but payment is still due April 30

Interest begins accruing the day after April 30 at the CRA's prescribed rate, compounded daily.

How to Pay the CRA

What If You Cannot Pay?

The CRA is not unreasonable. If you genuinely cannot pay your full balance, contact them as early as possible. In many cases, the CRA will work with you on a payment arrangement — a structured plan to pay off your balance over time. Interest and penalties will still apply, but acting proactively prevents the situation from escalating.

Do not ignore a balance owing. The CRA can — and does — withhold future refunds, intercept GST/HST credits, and in serious cases, pursue legal collection action.

5. Tax Instalments: Who Pays Them and How

Most Canadians whose taxes are withheld at source by their employer never need to think about instalments. But if you are self-employed, have investment income, rental income, or owed more than $3,000 in net taxes in both the current year and one of the two previous years, the CRA may require you to make quarterly instalment payments.

Instalment Due Dates

• March 15
• June 15
• September 15
• December 15

The CRA will send instalment reminders in February and August if they believe you meet the threshold. You can use their suggested amounts, base your payments on the prior year's tax bill, or estimate based on your projected current-year income.

If your instalments are insufficient, the CRA may charge instalment interest. If you overpay, the excess is applied to your next return as a credit.

6. How to Amend Your Tax Return After Filing

Forgot to claim an RRSP contribution? Missed a deduction? Received a tax slip after you filed? You can fix it — and it is easier than most Canadians think.

Wait until you receive your NOA before submitting any amendment. The CRA needs to fully assess your original return first.

How to Request a T1 Adjustment

The formal process for amending a Canadian personal tax return is called a T1 Adjustment Request (T1-ADJ). You have two options:

• Online via CRA My Account: Use the "Change my return" service. This is the fastest method — most online adjustments are processed within 2 weeks. You can adjust returns for the previous 10 calendar years.
• By mail: Complete Form T1-ADJ, attach supporting documents (receipts, slips), include your SIN and tax year, and mail it to your tax centre. Allow up to 8 weeks for processing.

What Can You Change?

• Add a missed deduction or credit
• Report income you forgot to include
• Correct a calculation error
• Claim carryforward amounts you did not apply
• Add RRSP contributions made in the first 60 days of the year

The CRA will reassess your return and issue a new NOA reflecting the updated amounts.

7. CRA Reviews and Audits: What to Expect

Each year, the CRA selects a portion of returns for further review. Being selected does not mean you did anything wrong — it is often a routine verification process, though it helps to understand the difference between a CRA review vs. an audit.

Types of CRA Reviews

• Processing review (desk review): The most common type. The CRA asks you to provide documents supporting a specific claim on your return — such as receipts for medical expenses, charitable donations, or home office deductions. You respond by mail or through your CRA My Account Message Centre.
• Pre-assessment review: Happens before your NOA is issued. The CRA pauses processing to request clarification on a specific item.
• Audit: A more in-depth examination of your return, financial records, and possibly your business activities. Far less common than a processing review, and reserved for higher-risk situations.

Red Flags That May Trigger a Review

• Large or unusual deductions compared to your income level
• Consistently reporting business losses year after year
• Significant changes in income from one year to the next
• Claiming home office expenses without being self-employed
• Rental income that does not match T4A slips from tenants
• Cryptocurrency transactions not reported

What to Do If You Receive a CRA Review Letter

1. Read the letter carefully — the CRA will specify exactly what they need.
2. Gather your supporting documents (receipts, invoices, bank statements).
3. Respond by the deadline stated in the letter.
4. Submit documents through CRA My Account, by mail, or by fax.
5. Keep copies of everything you send.

Responding promptly and completely is the single most important thing you can do. Most reviews are resolved quickly once you provide the requested documentation.

8. How Long to Keep Your Tax Records

Knowing exactly how long to keep your tax records is essential, as the CRA can request supporting documents for up to six years from the end of the tax year in question. This means you must keep:

• Your filed tax return (keep a copy)
• All T4s, T4As, T5s, and other slips
• Receipts for all claimed deductions (medical, charitable, childcare, moving)
• RRSP contribution receipts
• Business records (invoices, expenses, bank statements) — if self-employed
• Property records (purchase price, capital improvements) — until 6 years after you sell

Practical rule: Keep records for 7 years to give yourself a comfortable buffer. Digital backups stored in cloud services are strongly recommended — they are searchable, do not take up physical space, and survive house fires.

Example: Your 2026 tax return and all supporting documents should be kept until at least December 31, 2031.

9. Benefits and Credits That Start (or Continue) After Filing

One of the most important reasons to file your taxes — even if you owe nothing — is to access benefits and credits that the CRA distributes based on your return.

Key Benefits Triggered by Your Tax Return

The CRA uses your filed return to calculate your entitlement to these benefits for the July-to-June benefit year. Filing on time — even with zero income — ensures you do not miss a single payment.

10. What Self-Employed Canadians Need to Watch For

If you are self-employed or run a small business, your post-filing obligations go beyond what most employees face.

The June 15 Filing Deadline Does Not Extend Your Payment Deadline

This is the most common misunderstanding among self-employed Canadians. You have until June 15 to file your T1 return, but any taxes owing must be paid by April 30. Interest on unpaid balances starts accruing May 1 — regardless of your filing deadline.

Best practice: Estimate your balance before April 30 and pay at least that amount, even if you have not finalized your return yet. You can always file the return in June.

GST/HST and QST Are Separate Obligations

Filing your T1 personal income tax return does not settle your GST/HST or QST remittances. These are separate filings with separate deadlines. Annual filers who are self-employed have a GST/HST return deadline of June 15, but the payment is due April 30.

Review Your NOA for T4A Adjustments

The CRA cross-references T4A slips (payments received for services) with the self-employment income you reported on your T2125. If a T4A issued to you was not accurately reflected in your return, the CRA may assess additional income. Compare your NOA carefully against what you filed.

Start Setting Aside Taxes for Next Year Now

The most financially healthy habit for self-employed Canadians is to treat a percentage of every payment received as money already owed to the CRA. A common approach is to set aside 25–30% of net income in a separate savings account dedicated solely to taxes. When tax season arrives, the money is there — and any surplus becomes a bonus.

11. Your Rights as a Canadian Taxpayer

Many Canadians do not realize they have formal, legal rights when interacting with the CRA. The Taxpayer Bill of Rights guarantees you 16 rights, including:

• The right to receive entitlements and to pay no more and no less than what is required by law
• The right to be treated professionally, courteously, and fairly
• The right to a formal review and a subsequent appeal
• The right to relief from penalties and interest under certain circumstances
• The right to lodge a service complaint and be provided with a formal CRA review

Disagreeing With Your Assessment

If you believe the CRA made an error in your assessment or reassessment, you have options:

1. Request an amendment (T1-ADJ): If you have new information or missed a deduction, this is the simplest first step.
2. File a formal objection: You have 90 days from the date of your NOA to file a Notice of Objection. This formally disputes the CRA's assessment.
3. Appeal to the Tax Court of Canada: If your objection is rejected and you still disagree, you can appeal to the Tax Court. Independent legal advice is strongly recommended at this stage.

Taxpayer Relief — Penalties and Interest

Through the taxpayer relief provisions, the CRA can waive or cancel penalties and interest in situations beyond your control — serious illness, natural disaster, financial hardship, or CRA errors. Use Form RC4288 or apply through CRA My Account. Requests must relate to interest that accrued within the last 10 calendar years.

• ☐ If self-employed: confirm GST/HST return and payment deadlines

13. Frequently Asked Questions

What happens immediately after I file my taxes in Canada?

The CRA receives your return and begins processing it. For online filers, this starts within hours. You can track progress through the CRA Progress Tracker in your CRA My Account. The CRA will issue a Notice of Assessment (NOA) confirming the result — typically within 2 weeks for online filers.

How long does the CRA take to process a tax return?

Online returns filed before the deadline are typically processed within 2 weeks. Paper returns can take up to 8 weeks. Non-resident returns can take up to 16 weeks. Returns selected for review may take longer.

When will I get my CRA tax refund?

If you filed online and have direct deposit, your refund typically arrives within 8 business days of your Notice of Assessment being issued. Without direct deposit, a refund cheque can take up to 8 weeks. Paper filers should allow additional time on top of the 8-week processing window.

What does my Notice of Assessment mean?

Your NOA is the CRA's official summary of your assessed tax return. It shows whether you have a refund, owe money, or have a zero balance. It also shows your updated RRSP contribution room, any carryforward amounts, and your NETFILE access code. Read it carefully — it is a legally significant document.

What if I made a mistake on my tax return after filing?

Wait for your NOA first, then request a T1 Adjustment through CRA My Account or by mailing Form T1-ADJ. You can amend returns going back up to 10 years. The CRA will reassess and issue an updated NOA. Never file a second tax return for the same year.

What happens if I owe taxes and cannot pay by April 30?

Interest will begin accruing on May 1 at the CRA's prescribed rate, compounded daily. A late-filing penalty of 5% of the balance owing (plus 1% per month, up to 12 months) also applies if you filed late. Contact the CRA proactively to discuss payment arrangements before the situation worsens.

Can the CRA audit me after I file?

Yes. The CRA can review or audit a return for up to 3 years after the date of your original NOA (longer in cases of suspected fraud or misrepresentation). Most Canadians are selected for routine processing reviews, not full audits. Keeping clean records for 6+ years is your best defence.

How do I check the status of my CRA refund?

Log into your CRA My Account and use the Progress Tracker. You can also call the CRA's automated Tax Information Phone Service (TIPS) at 1-800-267-6999. Have your SIN, birth date, and the total income from your return ready.

Do I need to file taxes if I have no income?

You are not legally required to file if you have no income — but you likely should. Filing with zero income is how you access the GST/HST Credit, Canada Child Benefit, provincial benefits, and how you build RRSP contribution room. Missing even one filing year can create gaps in your benefit payments.

What happens to my benefits after I file?

The CRA uses your most recently filed return to calculate your entitlement to income-tested benefits like the GST/HST Credit, Canada Child Benefit, and provincial credits. The benefit year runs from July to June. Filing by April 30 ensures your benefits are recalculated without interruption starting in July.

How long should I keep my Canadian tax records?

Keep all tax documents for a minimum of 6 years from the end of the tax year they relate to. For business owners, keep records for 6 years from the date your return was due or filed, whichever is later. Property records should be kept until 6 years after the year you sell or dispose of the property.

What is the difference between a CRA review and a CRA audit?

A review (or processing review) is a routine request for documents to verify a specific claim on your return — most commonly charitable donations, medical expenses, or home office deductions. It is not an audit. An audit is a deeper examination of your overall financial records and is far less common. Respond promptly and completely to either type of CRA request.

What if I disagree with my Notice of Assessment?

First, review the explanation of changes section of your NOA to understand what the CRA modified. If you have documentation supporting your original position, file a T1 Adjustment. If you formally disagree with the CRA's assessment, you have 90 days from the NOA date to file a Notice of Objection. After that, you may appeal to the Tax Court of Canada.
