How to Do a Tax Return in Canada: Your Complete Guide

Doing your tax return every year is one of those things that sounds more complicated than it actually is. Once you understand what a tax return is, what you need, and how the process works, most people find it is pretty manageable.

This guide is written in plain language for everyday Canadians. Whether you are doing your tax return for the first time or you just want to make sure you are doing it correctly, this will walk you through the whole thing from beginning to end.

What Is a Tax Return in Canada?

A tax return is a form you fill out and submit to the Canada Revenue Agency (CRA) every year. It tells the CRA:

• How much money you earned during the year
• What deductions and credits you are entitled to
• How much tax you owe, or how much refund you should receive

In Canada, the main tax return form for individuals is called the T1 General Return. It is used by employees, self-employed people, retirees, students, and most other residents. The CRA uses the information on your return to calculate whether you owe more tax, or whether you paid too much and are owed a refund.

When people say they are doing their taxes, filing their return, or completing their tax return – they all mean the same thing: filling out this form and sending it to the CRA.

Who Has to Do a Tax Return in Canada?

You are required to file a tax return in Canada if:

• You have taxes owing to the CRA
• You want to claim a refund
• The CRA has requested that you file
• You received certain types of income (employment, self-employment, rental, investment, or foreign income)
• You want to receive benefit payments like the GST/HST credit, Canada Child Benefit, or Ontario Trillium Benefit
• You made contributions to the Canada Pension Plan (CPP) on self-employment income
• You sold a property or have capital gains to report

Even if you made very little money or no money at all, it is still worth filing. The CRA uses your return to determine your eligibility for government benefits and credits – and you will not receive them if you do not file.

What Is the Difference Between a Tax Return and a Tax Refund?

This is a question many Canadians have, so let us clear it up:

A tax return is the form or document you fill out and submit to the CRA. It is the process of reporting your income and calculating your tax.

A tax refund is the money the CRA sends back to you if you overpaid taxes during the year – usually because too much was deducted from your paycheques by your employer.

So: you do a tax return, and as a result, you may receive a tax refund. Or you may find out you owe more tax. Or you might owe nothing and get nothing back – but you still need to file the return.

What Do You Need to Do Your Tax Return?

Before you sit down to do your taxes, gather these documents:

Personal Information

• Your Social Insurance Number (SIN)
• Your date of birth
• Your home address as of December 31 of the tax year
• Your spouse or common-law partner’s name, SIN, and net income (if applicable)
• Names and dates of birth of any dependant children

Income Documents (Tax Slips)

• T4 – Employment income (from your employer)
• T4A – Pension, RRSP, or other income
• T4E – Employment Insurance benefits
• T5 – Investment income (interest, dividends)
• T3 – Trust income (from mutual funds or ETFs held outside registered accounts)
• T4RSP / T4RIF – RRSP or RRIF withdrawals
• Records of rental income and expenses
• Records of self-employment income and expenses

Deduction and Credit Documents

• RRSP contribution receipts
• Receipts for medical expenses
• Child care expense receipts
• Charitable donation receipts
• Union or professional dues receipts
• T2202 – Tuition tax certificate (from a university or college)
• Home office expense records (if you work from home)
• Moving expense receipts
• Previous year’s Notice of Assessment (for RRSP contribution room)

Bank Information

Your bank account number, transit number, and institution number – for setting up direct deposit with the CRA so your refund arrives faster.

How to Complete Your Tax Return: Step by Step

Step 1: Confirm Your Filing Status and Residency

Are you filing as a Canadian resident? Most people living in Canada full-time are tax residents. If you moved to Canada during the year, you are a tax resident from your arrival date. If you left Canada permanently during the year, you file as a part-year resident.

Step 2: Choose Your Filing Method

• Online using NETFILE-certified software (fastest, most popular)
• By paper (mail your completed T1 to the CRA tax centre for your province)
• Through a tax professional or accountant

Step 3: Enter Your Personal Information

Fill in your name, SIN, date of birth, address, marital status, and province of residence as of December 31 of the tax year.

Step 4: Report Your Income

Enter all income from your tax slips – employment income from your T4, investment income from your T5, any pension income, rental income, self-employment income, and any other amounts you received during the year.

Step 5: Claim Your Deductions

Enter any deductions you are entitled to – such as RRSP contributions, child care expenses, moving expenses, employment expenses (if your employer gave you a signed T2200), and support payments made.

Step 6: Claim Your Tax Credits

Claim all applicable non-refundable and refundable credits – including the basic personal amount, medical expenses, charitable donations, tuition credits, and any provincial credits you qualify for.

Step 7: Review and Submit

Review your return carefully before submitting. If you are using certified software and filing via NETFILE, submission is done electronically through the CRA’s secure system. If you are filing by paper, sign and mail your T1 to the correct CRA tax centre.

How to Do Your Tax Return Online in Canada

Filing online is the fastest and most accurate way to complete your Canadian tax return. Here is how it works:

• Choose a CRA-certified NETFILE software (many options are available, including free versions for simple returns)
• Create an account or sign in
• Import your tax slips automatically using the CRA’s Auto-fill my return feature (available if you have a CRA My Account)
• Follow the software prompts to enter your income, deductions, and credits
• Submit directly to the CRA via NETFILE
• Receive your Notice of Assessment within days (compared to weeks for paper filing)

Can You Do a Tax Return for Free?

Yes. Many Canadians with simple tax situations can file for free using CRA-certified NETFILE software. The CRA also lists approved free filing options on its website.

Additionally, the Community Volunteer Income Tax Program (CVITP) provides free tax filing help from trained volunteers for eligible individuals – including seniors, newcomers, people with modest incomes, and those with disabilities.

If your situation is more complex – self-employment, rental income, capital gains, multiple provinces – working with a tax professional like Taxccount ensures your return is accurate and optimized.

What Can You Claim on Your Tax Return?

Common deductions and credits Canadians can claim include:

• RRSP contributions
• Child care expenses
• Medical expenses
• Charitable donations
• Employment expenses (with a signed T2200 from your employer)
• Home office expenses
• Moving expenses (if you moved for work or school)
• Tuition credits (T2202 from your school)
• Basic personal amount (available to every Canadian)
• Caregiver amounts
• Disability tax credit (if eligible)

The more accurately you claim what you are entitled to, the lower your tax bill – or the larger your refund.

What Happens After You Submit Your Tax Return?

Once the CRA receives your return, it will process it and send you a Notice of Assessment (NOA). This document confirms:

• Whether you owe additional tax or will receive a refund
• Your RRSP contribution room for the following year
• Any adjustments the CRA made to your return
• Your carry-forward amounts for credits and losses

If you are owed a refund, it will be deposited to your bank account (if you have direct deposit set up) or mailed as a cheque. Online filers typically receive their refund within two weeks. Paper filers may wait six to eight weeks or longer.

Common Tax Return Mistakes to Avoid

• Filing late – The deadline for most individuals is April 30. Self-employed individuals have until June 15, but any balance owing is still due by April 30. Late filing triggers penalties and interest.
• Missing income slips – All T4s, T5s, and other slips must be reported. The CRA receives copies from your employers and financial institutions and will match them against your return.
• Forgetting to claim deductions and credits – Many Canadians miss RRSP deductions, medical expenses, or credits they are entitled to.
• Incorrect SIN or banking details – Errors in your Social Insurance Number or direct deposit information can delay your refund or cause CRA issues.
• Not filing because you think you owe nothing – Even if you owe no tax, not filing means you lose access to GST/HST credits, Canada Child Benefit, and other programs.
• Ignoring CRA mail – If the CRA sends a request for more information or a review notice, respond promptly to avoid penalties.

Frequently Asked Questions

What is the deadline to file a tax return in Canada?

For most individuals, the deadline is April 30. Self-employed individuals and their spouses have until June 15 to file, but any balance owing must still be paid by April 30 to avoid interest charges.

Do I have to file a tax return if I have no income?

You are not legally required to file if you have no income and no taxes owing, but it is strongly recommended. Filing even with no income keeps you eligible for GST/HST credits, Canada Child Benefit, and other government benefit payments.

How long does it take to get a tax refund in Canada?

If you file online and have direct deposit set up, most refunds arrive within two weeks of the CRA accepting your return. Paper filers may wait six to eight weeks or longer.

Can I file my tax return for previous years?

Yes. The CRA allows you to file returns for prior years, and you may be able to recover refunds and credits you missed. There is generally a 10-year limit on claiming refunds for past years.

What is the CRA My Account and do I need it?

CRA My Account is a secure online portal where you can view your tax information, check benefit payments, update personal details, and use the Auto-fill feature to import your slips directly into tax software. It is not required but makes filing significantly easier.

What happens if I make a mistake on my tax return?

You can correct errors by submitting a T1 adjustment request through CRA My Account or by mailing a completed T1-ADJ form. The CRA will review the change and issue an updated Notice of Assessment.
