How to File Taxes in Canada for the First Time as a Newcomer (2026)
Updated
A newcomer’s first Canadian return differs from a regular one in four ways: it starts on the date you became a resident, it asks about income you earned abroad, it may need a SIN you are still waiting for, and it is what starts your benefits. This page covers those parts. Whether you are a resident at all depends on your ties to Canada; the tests are in am I a Canadian tax resident?. The general filing process, the same for everyone, is summarised in the guide to filing a tax return, and filing taxes for the first time walks through the steps any first-time return involves.
Your Residency Start Date: Why It Matters
Concept
Detail
Residency start date
The date you established Canadian tax residency, typically your arrival date
Effect on income
Only income earned ON or AFTER this date is taxed in Canada
Effect on benefits
Benefit eligibility (CCB, GST/HST credit) starts in the year you file
Disclosed pre-arrival income
Foreign income before arrival is reported for benefit-testing but is not taxed in Canada
Where to enter it
T1 federal tax return: “Date you became a resident of Canada”
What Income to Report on Your First Canadian Return
18% of the previous year’s earned income (so your first year of income creates room for the next year)
Up to $33,810 in 2026
TFSA room
$7,000/year from January 1 you turn 18 as Canadian resident
Accrues only from year of residency
Common First-Year Filing Mistakes
Mistake
Why it matters
Not disclosing pre-arrival foreign income
Even if not taxable, it affects benefit calculations
Forgetting TFSA room only starts accruing from the year of residency arrival
Lifetime room from 2009 doesn’t apply; My CRA Account shows the actual figure
Missing T1135 for foreign assets over $100,000 CAD
Penalties are severe: $25/day up to $2,500 for late filing
Not filing at all because income was low
Filing is what triggers benefits and starts your contribution room (filing with no income)
Using the wrong residency start date
The landing record date applies, not a passport renewal date or permit issue date
