Filing your tax return

Filing your tax return is a key responsibility when you settle in Canada. Whether you are an employee, self-employed, or a student, understanding the deadline, gathering the right documents, and choosing a filing method will help you avoid penalties and claim any refund or benefits you are entitled to.

Know Your Deadline

For most people in Canada, the tax return deadline is April 30. This applies to employees, retirees, and students. If you or your spouse is self-employed, you have until June 15 to file, but any taxes you owe must still be paid by April 30 to avoid interest charges. Missing the April 30 deadline can result in penalties and interest, and may disrupt your access to government benefits such as the Canada Child Benefit or GST/HST Credit.

Gather Your Tax Documents and Records

T4 Slips and Other Income Slips

Your employer must provide you with a T4 slip by the end of February. The T4, officially called a Statement of Remuneration Paid, reports your total employment income for the year and shows how much income tax, Canada Pension Plan (CPP), and Employment Insurance (EI) your employer deducted from your pay. It is essential for filing your return accurately. If you had multiple jobs, you will receive a separate T4 from each employer and must report all of them.

Depending on your income sources, you may also receive other slips. A T4A slip reports pension income, self-employment income, scholarships, or other payments. A T5 slip reports investment income such as interest and dividends. Keep all slips until you file, and check them carefully for errors—contact your employer or the issuer immediately if amounts appear wrong.

Keeping Receipts and Records

Keep all receipts, invoices, and documents that support deductions or credits you plan to claim. This includes receipts for childcare expenses, medical costs, home office supplies, educational expenses, and charitable donations. The Canada Revenue Agency (CRA) recommends keeping tax documents for at least six years in case of audits or reassessments. Having organized records makes filing faster and protects you if questions arise later.

File Online Using NETFILE-Certified Software

The fastest and most secure way to file your tax return is electronically using NETFILE-certified tax software. The CRA approves certain software products each year that meet strict security and accuracy standards. When you file electronically through NETFILE, refunds are processed faster—typically within 8 to 10 business days if you use direct deposit.

Free and Low-Cost Options

Good news: you do not have to spend money to file your taxes online. Many CRA-certified software providers offer free versions, especially if your income is modest or your tax situation is straightforward. Options include Wealthsimple Tax (pay-what-you-want model), GenuTax (completely free), CloudTax Free, and the free versions of TurboTax and UFile. If you have a more complex tax situation, some software offers a small fee for extra features and support. The CRA's website lists all certified software providers so you can compare options before choosing.

What You Need to File Online

• Your Social Insurance Number (SIN)—a 9-digit identifier you need to work and file taxes in Canada
• Your T4, T4A, T5, or other income slips from your employer or financial institutions
• Information about any deductions or credits you are claiming
• An access code (found on your previous year's Notice of Assessment) if you have one, though this is optional

Once you have your documents ready, open the NETFILE-certified software, enter your information, and the software will calculate your tax. Then you submit your return electronically directly to the CRA. You will receive confirmation that the CRA received your return.

Use CRA My Account

My Account is a secure online portal where you can manage your personal income tax and benefit information anytime. To register, you will need your SIN, date of birth, and information from a recent tax return. You can sign in using a Sign-In Partner (like your bank's login), a CRA user ID and password, or a provincial partner account if you live in Alberta or British Columbia.

Once you have access to My Account, you can view your tax slips, check the status of your refund, see your Notice of Assessment, track benefit payments like the Canada Child Benefit, update your banking information for direct deposit, and use the Auto-fill My Return feature to populate your tax software with CRA data. Having a CRA account makes the filing process much more efficient, especially if you file online.

If You Are New to Canada

As a newcomer, you may be filing your first Canadian tax return. If you became a permanent resident (PR) partway through the year, you must still file a return reporting all worldwide income earned while you were in Canada. If you worked before obtaining PR status, include that income as well. When you file, the CRA will determine your residency status for tax purposes and calculate your obligations accordingly.

To file your taxes, you will need a Social Insurance Number (SIN). Apply for one as soon as you arrive in Canada through Service Canada. You can apply in person at a Service Canada office, online, or by mail. If you apply in person, you will receive your SIN immediately. Online applications typically take 1-3 business days to process, and mail applications take about 15-25 business days. There is no fee to apply for a SIN.

Pay Any Taxes Owing

If your return shows that you owe taxes, you can pay online, by phone, in person, or by mail. The CRA accepts many payment methods, including credit cards, debit, online banking, and installment payments. If you cannot pay the full amount by April 30, contact the CRA to arrange a payment plan. Paying late will result in compound daily interest, but making a plan with the CRA is better than not filing or paying at all.

Self-Employed and Business Income

If you are self-employed or own a business, the filing deadline is June 15. However, any taxes you owe are still due on April 30. You must report all business income on your return and may be able to claim business expenses to reduce your taxable income. Keep detailed records of all business income and expenses, including invoices, receipts, and bank statements, to support what you report to the CRA.
