How to File Your Taxes in Canada: A Step-by-Step Guide

Know your deadline and why filing matters

For most individuals, the personal income tax deadline falls on April 30 following the tax year, and self-employed individuals (and their spouses) typically get a bit longer to file, though any balance owing is still generally due by the April deadline. These dates can shift when they land on a weekend or holiday, so always confirm the exact date for the current tax year on the CRA website before you file.

Filing isn't only about paying what you owe. It's also how the CRA calculates and issues benefits many Canadians rely on, including the GST/HST credit, the Canada Child Benefit, and various provincial credits. Skipping a return, even with no income to report, can mean missing out on money you're otherwise entitled to.

If you owe money and file late, the CRA charges a late-filing penalty plus daily interest on the unpaid balance, so filing on time (even if you can't pay in full right away) is almost always the better move.

Gather your documents before you start

Most of the information you need arrives as slips, either by mail or through your CRA My Account. Common ones include:

• T4 slips for employment income
• T4A for pension, scholarship, or other income
• T5 slips for investment income like interest and dividends
• T2202 for tuition if you're a student
• RRSP contribution receipts
• Receipts for eligible deductions and credits, such as childcare, medical expenses, or charitable donations

If you're self-employed, you'll also need your business income and expense records for the year. It helps to log into CRA My Account ahead of time, since many slips are available there and can often be imported automatically into certified tax software through a feature called Auto-fill my return.

Choose how you'll file

You have a few legitimate ways to submit your return to the CRA:

• NETFILE: file yourself using CRA-certified tax software. Many certified programs offer a free tier for simple returns, and NETFILE is the most common way individuals file today.
• EFILE through a tax professional or accountant, who prepares and transmits the return on your behalf.
• Paper return, mailed to the CRA, which still works but takes longer to process.
• Free community clinics run through the Community Volunteer Income Tax Program (CVITP), for people with modest income and a simple tax situation.
• The CRA also invites some eligible lower-income filers with very simple returns to use a free automated filing service; if you qualify, you'll typically get a letter or see the option in your CRA My Account.

Whichever method you choose, double-check your personal information (address, marital status, direct deposit details) is current, since that affects both your refund timing and your benefit payments.

After you file

Once the CRA processes your return, you'll receive a Notice of Assessment (NOA), either by mail or in your CRA My Account if you've opted for electronic delivery. The NOA confirms what the CRA calculated, shows your refund or balance owing, and includes your updated RRSP deduction limit for the following year.

If you're owed a refund, direct deposit is the fastest way to receive it. If you owe money, you can pay through your online banking bill-payment system, CRA My Account, or in person, and you can ask the CRA about a payment arrangement if you can't pay the full amount at once.

Keep your slips, receipts, and a copy of your filed return afterward. The CRA can ask to review or audit a return for several years after filing, so having your records organized saves a lot of stress if that happens.
