Your First Canadian Tax Return: The Real Filing Guide

Learning to file your first Canadian tax return feels intimidating mostly because of unfamiliar vocabulary, slips, deductions, NETFILE, not because the actual process is genuinely complicated. Once you understand the handful of pieces that actually matter, it stops being a mystery.
Ten years in Canada’s settlement sector, the last eight leading a team in Regina, and I’ve sat with newcomers through this exact process more times than I can count. Here’s the plain-language version.
This post covers how to file your first Canadian tax return: why you should file even with little income, when your tax residency actually starts, the slips you’ll need, how to actually file, and what happens after. Let’s get into it!


File your first Canadian tax return even with little or no income
A lot of newcomers assume that if they earned little or no income in their first partial year, there’s no point filing a return. That assumption costs people money. Filing is often what triggers eligibility for benefits like the GST/HST credit and Canada Child Benefit, covered in detail in our guide to government benefits for newcomers. File a return even in a year with minimal income, it’s usually the reason those benefits start flowing at all.

Tax residency: when you actually start reporting
Your tax residency in Canada generally begins when you establish significant residential ties here, this is not always the exact same date as your immigration landing date, though for many people it lines up closely. From that date forward, you generally need to report your world income, not just income earned in Canada.
This distinction matters and can be genuinely confusing in your first year, so confirm your specific residency start date situation against the CRA’s own newcomer tax residency guidance rather than assuming a simple rule applies to everyone.

The slips you’ll need
If you worked as an employee, your employer issues a T4 slip showing your income and deductions, usually by a set date early in the year. Other common slips include a T4A for certain other income and a T5 for investment income. Keep every slip that arrives, even ones you’re not sure apply to you, it’s much easier to set aside a slip you didn’t need than to track one down later that you missed.

Taxes are one piece of your first year. Your First Year in Canada walks through immigration, banking, credit, healthcare, and settling in end to end.

How to actually file
Most people file online using CRA-certified NETFILE tax software, many of which are free for straightforward returns. You’ll need your Social Insurance Number and your slips for the smoothest experience. If your situation feels complicated, foreign income, a partial year of residency, or multiple income sources, consider getting help rather than guessing, especially in your first year when the rules are least familiar.
Software walks you through the process with plain-language questions rather than the raw government form, which makes the whole thing far less intimidating than it sounds. Set aside a quiet hour, have your slips in front of you, and go through it step by step rather than trying to rush it between other tasks, most mistakes happen from moving too fast, not from the process itself being genuinely difficult.

After you file
Once submitted, the CRA reviews your return and issues a notice of assessment confirming what they calculated. If you owe money or paid too much during the year, this notice tells you the difference. Keep that notice of assessment somewhere safe once it arrives, landlords, lenders, and even some immigration applications sometimes ask for it as proof of income, so it’s worth more than just settling that year’s taxes.
If your income is genuinely low and the process still feels like too much to navigate alone, free tax clinics in many communities can file for you at no cost if you qualify, ask your local settlement agency which clinic is currently running near you.
Learning how to file your first Canadian tax return connects directly to several other pieces of settling in well. If you’re also working through language classes, transferring foreign professional credentials, or medical coverage, those are all worth tackling around the same time as your first return.
