Your First Tax Return in Canada: The Simple Version
Your employer gives you a T4, and it looks as if the tax work is finished. Tax came off every paycheque. The slip has official boxes and numbers. What else could be missing?
Think of the T4 as one page of your year, not the whole book. Your first Canadian return may also need the date your tax life in Canada began, another job, side work, income from outside Canada, and basic family information.
You do not need to learn the entire tax system. This guide gives you the small map: what happens once a year, what belongs in the picture, what to gather, and when it makes sense to ask for help.
What actually happens at tax time?
Canada uses the calendar year for personal taxes. The process is easier to understand as four steps:
Key idea
A T4 is one page of the year. Your tax return is the whole story CRA assesses.
- During the year, you earn income. An employer usually deducts some tax from each paycheque.
- After the year ends, an employer gives you a T4 showing employment income and payroll deductions for that job.
- You file one tax return that brings together the parts of your year CRA needs to see.
- CRA reviews the return and sends a Notice of Assessment showing a refund, an amount owing, or neither.
When do you file your first return?
For newcomers, the first filing year starts with Canadian tax residency. Immigration status and tax residency are related questions, but they are not the same thing. For many newcomers, tax residency begins when they start living in Canada and establish their home and other important ties here.
You normally file after that calendar year ends. CRA's current example says that a person who became a Canadian tax resident in 2026 files the 2026 return by April 30, 2027.
If you are unsure when your tax residency began, do not choose a date from one immigration document and hope it is right. Write down when you arrived, where you lived, and where your immediate family was. That timeline is the useful starting point.
What may not appear on your T4?
A T4 describes one employee job. If you had two employers, each normally issues its own slip. Work you did as a contractor or on your own may not appear on a T4 at all.
The return may also need income earned outside Canada for the part of the year you were a Canadian tax resident. The date money reached a bank account does not tell the whole story, so keep notes about when the work was done and what the payment was for.
Your arrival date, spouse or common-law partner, children, and changes during the year can also matter. None of these facts is proof that the return is complicated. They are simply pages that may belong in the same book.
What should you gather first?
You do not need a perfect folder. Start with one page for the story of your year and a second place for the documents.
- the date you arrived and began living in Canada
- every T4 and the last pay statement from each job
- a plain list of other work or income, including income from outside Canada during your resident period
- your spouse or common-law partner and children's basic information, when applicable
- receipts or records you think may matter, even if you are not sure where they belong
- any CRA letter or notice you have already received
Can you file the first return yourself?
Yes, sometimes. If you have one clear T4, a straightforward residency date, no other income, and simple family facts, certified tax software or an eligible free tax clinic may be a reasonable route. Most first-time filers with a SIN or qualifying temporary tax number can file online without having a CRA account first.
A review becomes more useful when the year includes another job, contractor or self-employed work, income from outside Canada, an uncertain residency date, a spouse abroad, missing slips, or a CRA letter.
This is not a test of how many forms you know. It is a choice between a year you can describe confidently and a year where one missing fact may change the return.

Yes. Payroll deductions are advance payments based on that job. The annual return brings together the relevant parts of your year, and CRA's assessment determines the final result.
If you became a Canadian tax resident in 2026, CRA's current newcomer guidance says the 2026 return is due by April 30, 2027. The residency start date depends on your facts, not immigration status alone.
No. Most first-time filers with a SIN or qualifying temporary tax number can use certified tax software without a CRA account. After CRA assesses the first return, you can register for an account using the Notice of Assessment.
Ask the employer for a copy first. If the issuer sent the slip to CRA, it may also be available from CRA. Reliable pay records can help when a slip cannot be obtained; do not silently leave the income out.
Yes. Tell the preparer about income from outside Canada and when it was earned. Income for the part of the year you were a Canadian tax resident may need to be reported, and the exact treatment depends on the facts.
