How do you file Canadian taxes as a newcomer in 2026?

You file for the year you become a resident. A mid-year arrival still uses that calendar year return, due the following spring. Enter the date you became a resident for tax purposes on the newcomer lines. Report world income in Canadian dollars for the resident portion of the year: Canadian wages plus foreign income earned while you were resident. Provincial tax usually follows where you lived on 31 December.

You need a Social Insurance Number to file online. If the SIN is delayed and the deadline is close, CRA allows a paper return with a note explaining the missing SIN: get a SIN. Certified software can NETFILE many first returns without a prior CRA account. After assessment, register CRA My Account to see slips, notices, and registered-plan room.

GST/HST credit, Canada child benefit, and related provincial payments can start after you arrive if you apply and meet status rules, but CRA expects annual returns from both spouses or partners to keep payments flowing even when income is low. Direct deposit needs a Canadian bank account: open a bank account.

RRSP room builds mainly from Canadian earned income reported on prior returns, so large first-year RRSP deductions are often limited: set up an RRSP. TFSA room follows residency years instead: set up a TFSA. Keep notices of assessment; adult citizenship applications may ask about tax filing within the eligibility window: apply for citizenship.
