Tax season officially kicks off next month, and the Canada Revenue Agency just released its new list of updates for the 2025 tax year.
Announced on Tuesday, the CRA updates cover everything from adjusted tax brackets and new credits to changes in how you access your online account.
Some of the updates are already in effect, while others will roll out later this year and impact how much tax you owe — or how much you could get back.
Key dates & deadlines
The 2025 tax season officially kicks off on Monday, February 23, 2026, when the CRA will open its NETFILE service and begin accepting tax returns for the year.
After that, here are the main dates to mark on your calendar:
March 2, 2026: Deadline to contribute to an RRSP, pooled registered pension plan (PRPP) or specified pension plan (SPP) for the 2025 tax year
March 2, 2026: Deadline for your employer to give you your T4 slip (and file their T4 summary with the CRA)
April 30, 2026: Deadline to file your tax return and pay any balance owing
June 15, 2026: Filing deadline if you're self-employed (or your partner is) — but keep in mind you still have to pay any taxes owing by April 30
