The RRSP contribution deadline for the 2025 tax year is March 2, 2026 - exactly 60 days after the end of the calendar year. Any contributions you make to your Registered Retirement Savings Plan between January 1, 2025 and March 2, 2026 can be claimed as a deduction on your 2025 tax return, lowering your taxable income for that year. The 2025 RRSP contribution limit is 18% of your 2024 earned income, up to a maximum of $32,490, minus any pension adjustment. Unused contribution room from prior years carries forward indefinitely, so if you have not contributed in past years, your room is likely much higher than the annual maximum. Check your most recent CRA Notice of Assessment for your exact RRSP deduction limit, or log into CRA My Account to see your current room.
