Filing Your First Tax Return in Canada: A Newcomer’s Walkthrough

The first tax return you file in Canada is the one that scares people the most. Not because it is hard — it usually isn’t — but because the CRA letter shows up in English, the forms ask questions in language nobody explains, and a lot of newcomers assume that if they did not earn much, they do not need to file at all.

That last part is the most expensive mistake. In Canada, filing a tax return is not just about paying tax. It is the key that unlocks the benefits the government already plans to give you — the GST/HST credit, the Canada Child Benefit, provincial credits, and a long list of others. If you do not file, you do not get them. Even if you earned zero dollars all year.

So let’s walk through the first return the way I would explain it to a cousin who just landed. Plain language. No jargon. Step by step.

What “filing a tax return” actually means

A Canadian tax return is one form (called the T1) where you tell the CRA three things: how much you earned, what you paid in tax already, and what credits or deductions you qualify for. The CRA does the math and either sends you a refund, asks you to pay the difference, or — most often for newcomers — tells you that you are owed benefits.

The tax year in Canada runs January 1 to December 31. The deadline to file is April 30 of the following year. So a 2025 tax year return was due April 30, 2026. Your 2026 return will be due April 30, 2027.

Are you actually a tax resident?

This is the part most newcomers get wrong. You don’t become a Canadian tax resident the day you get permanent residence or a work permit. You become a tax resident the day you establish residential ties here — usually the day you arrive with the intent to live in Canada, rent or buy a home, and start daily life.

That date matters because you only report world income from that day forward. If you arrived in Canada on August 15, you do not owe Canadian tax on the salary you earned in your home country from January to August. Only what came after August 15.

Write down your arrival date. You will need it on the front page of your return.

What you need to gather before you start

Pull these together first. Filing takes about an hour if you have everything ready, and three days of frustration if you don’t.

• Your Social Insurance Number (SIN). If you do not have one yet, get it from Service Canada before doing anything else.
• Your date of arrival in Canada.
• All T4 slips from any Canadian employer (they must send these to you by the end of February).
• Any T5 slips from banks if you earned interest on Canadian deposits.
• Rent receipts if you live in Ontario, Manitoba, or Quebec (some provincial credits ask for these).
• Tuition slips (T2202) if you studied in Canada.
• Records of medical expenses, donations, or childcare costs you paid in Canada.
• An estimate of any foreign income you earned after your arrival date.

How a first-timer actually files

Here is the part nobody tells you clearly. As a first-time filer, your options are more limited than for someone who has been in the system for years.

Option 1: NETFILE-certified free software

The CRA keeps a list of certified tax software at canada.ca. Several options are free for simple returns — Wealthsimple Tax and TurboTax Free are the two most newcomers use. You fill in the questions, the software prepares the return, and you submit it electronically through NETFILE.

This works as long as you have a SIN and the CRA has your basic information on file. If you were issued a SIN recently, it should work — but if NETFILE rejects your submission, you will need to file by paper for the first year.

Option 2: Paper filing

You download the T1 General form for your province from canada.ca, fill it out by hand or on screen, sign it, and mail it to the CRA tax centre that serves your region. It is slower (refunds can take eight weeks instead of two) but it always works.

If you have an ITN instead of a SIN, paper filing is usually your only option.

Option 3: Free help from a CVITP clinic

The Community Volunteer Income Tax Program runs free clinics across Canada for people with simple tax situations and modest incomes. Volunteers — trained by the CRA — file your return for you at no cost. Search “CVITP near me” or check canada.ca for clinic locations and dates.

This is the option I would point most newly landed immigrants toward in their first year. No shame, no catch, no upselling. Just someone who knows the forms helping you through.

The credits and benefits you don’t want to miss

This is the real reason filing matters. The CRA does not chase you down to give you money. You have to file, and the benefits start showing up.

GST/HST credit

A quarterly payment for low and modest-income residents. For newcomers, you actually apply using form RC151 in your first year rather than waiting for the next tax return cycle. The amount in 2025 was up to roughly $533 per year for a single adult and more for couples and families (verify the current 2026 figure at canada.ca).

Canada Child Benefit (CCB)

If you have kids under 18, this is the big one. Apply using form RC66 when you arrive — you don’t have to wait for a tax return. In 2025, the maximum CCB was up to about $7,800 per year for each child under 6 and about $6,570 for each child age 6 to 17, with the amount reducing as family income rises (verify current 2026 amounts at canada.ca/cra).

To keep receiving it year after year, both parents must file a tax return every year — even the parent who didn’t earn any income.

Provincial credits

Every province has its own credits stacked on top of the federal ones. Ontario has the Trillium Benefit. BC has its climate action tax credit. Quebec runs its own separate tax system entirely (Revenu Québec). The tax software will ask the right provincial questions automatically.

Canada Carbon Rebate

If you live in a province where the federal carbon pricing applies, you get a quarterly rebate just for filing your return. The amount varies by province and family size — check the current schedule at canada.ca because this program has been adjusted recently.

The foreign property question

On the T1 there is a question that catches a lot of newcomers off guard: did you own foreign property worth more than $100,000 CAD at any time during the year?

In your first year as a tax resident, you do not have to file the foreign property form (T1135). That requirement starts the year after you become a resident. But the year after that, if you still own a home, an apartment, foreign bank accounts, or investments back home worth more than $100,000 CAD combined, you must report it. Not paying tax on it — just reporting that it exists.

The penalties for missing this form are heavy. Anyone with significant assets back home should talk to an accountant in their second year, not their first.

What our parents’ generation got wrong

A lot of immigrant parents who came here in the 1980s and 90s did not file in their first year. Some did not file for several years. They did not know they were supposed to, nobody at the bank or settlement office told them clearly, and by the time someone explained it, they had already missed thousands of dollars in benefits that were never going to come back.

Common worries that aren’t really worries

“What if I make a mistake on the form?” The CRA assumes most mistakes are honest. If something is wrong, they send a letter asking for clarification. You fix it. Penalties only kick in for late filing or deliberate fraud.

“What if I owe money I can’t pay?” File anyway. Filing late is more expensive than filing on time and owing. The CRA offers payment arrangements if you can’t pay all at once.

“Will the CRA share my information with immigration?” No. Tax records are confidential. Filing taxes does not affect your status, your PR application, or your citizenship timeline. If anything, a clean filing history helps when you apply for citizenship — they ask about it.

“I only worked under the table — should I file?” Yes, and you should report that income. It still counts for benefits and for building RRSP room and CPP credits down the line. The CRA cares more about you participating in the system than about how perfect the first year looks.

One last thing: set up CRA My Account after your first return

Once the CRA processes your first return, you can register for CRA My Account online. This is the portal where you check refund status, see your benefit payments, update your address, and find your Notice of Assessment. From your second year onward, everything gets easier — auto-fill grabs most of your slips automatically, and you only fill in what’s new.

The first return is the hardest one you will ever file in Canada. After that, the system mostly remembers you. Get this one done, even if it feels overwhelming, even if you only earned a small amount, even if a CVITP volunteer has to do it for you. The benefits start flowing, the system starts recognizing you, and the worst part of being new is behind you.
