The RRSP contribution deadline for the 2025 tax year is Monday, March 2, 2026. (March 1 falls on a Sunday this year, so the CRA extends to the next business day.) Any contribution made between January 1 2025 and March 2 2026 can be deducted from your 2025 taxable income — meaning a tax refund next April.
Why the deadline is two months into the new year
The CRA gives you the first 60 days of the new calendar year to make contributions that count for the previous tax year. This lets you wait until you know your final income for the year (slips arrive in February) before deciding how much to contribute. It’s a planning window, not just a deadline.
The 2026 contribution-room math
Your annual RRSP room is 18% of your previous year’s earned income, capped at the annual maximum. For the 2025 tax year, that’s 18% of your 2024 income, capped at $31,560. Earned income includes employment + self-employment + rental + a few other categories.
- Example: You earned $80,000 in 2024. Your 2025 RRSP room is 18% × $80,000 = $14,400.
- Example: You earned $200,000 in 2024. Your 2025 room is capped at $31,560 (not 18% × $200K = $36,000).
- Carry-forward: Unused room from previous years stays available indefinitely. If you contributed $0 the last 5 years, that whole pool is still yours. Check your exact carry-forward number on your last Notice of Assessment or in CRA My Account.
How much should you actually contribute?
The honest answer: enough to drop your taxable income into a lower bracket if that’s feasible, but don’t contribute more than you’d otherwise save somewhere else. The RRSP’s value comes from the tax-refund gap between your contribution-year marginal rate and your retirement-year marginal rate. If you’re earning $50K now and expect retirement income at $40K, the refund-vs-future-tax gap is small. If you’re earning $120K now and expect to retire at $60K, the gap is huge.
Use our Canadian Tax Bracket Calculator to see your current marginal rate, then estimate what your retirement marginal rate will be. The contribution that drops you into the lower bracket is usually the right amount.
What if you miss the March 2 deadline?
Contributions made after March 2, 2026 count toward your 2026 tax year (filed in April 2027). The money still goes into your RRSP — you just don’t get the refund a year earlier. The CRA isn’t penalty-strict about this; you simply lose 12 months of timing advantage.
Over-contributing: the $2,000 buffer
The CRA allows you to over-contribute by up to $2,000 lifetime without penalty. You don’t get a tax deduction on that $2K, but it grows tax-deferred. Anything over $2,000 of over-contribution is taxed at 1% per month until you withdraw it.

FAQ
RRSP deadline FAQ
What is the RRSP deadline for the 2025 tax year?
March 2, 2026 (because March 1 falls on a Sunday, the CRA extends to the next business day). Contributions made on or before this date can be deducted from your 2025 taxable income.
What if I contribute on March 3, 2026?
The contribution counts toward your 2026 tax year (filed in April 2027). You don’t lose the contribution — it still grows tax-deferred — you just defer the tax refund by 12 months.
Can I make a contribution online at midnight on the deadline?
Yes, as long as it actually settles by the deadline. Major banks process electronic RRSP contributions in real-time; some online brokerages take 1-2 business days to settle. Don’t cut it too close — contribute by end of day Friday Feb 27 to be safe.
Where do I find my exact RRSP contribution room?
Three places: (1) Your last Notice of Assessment from the CRA, (2) CRA My Account → RRSP and TFSA section, or (3) by calling the CRA’s TIPS line at 1-800-267-6999.
Frequently asked questions
Should I prioritize my RRSP or my TFSA if I can only fund one?
It depends on your marginal tax rate. If you’re earning under about $55,000, the TFSA usually wins because your RRSP refund is small and you’d rather have tax-free withdrawals later. Above roughly $75,000, the RRSP refund gets meaningful — at $100K in Ontario you’re saving around 43 cents per dollar contributed, which is hard to beat.
If you’re somewhere in between, split the contribution. There’s no rule saying it has to be all-or-nothing, and the TFSA room carries forward too.
Can I contribute to a spousal RRSP before the March 2, 2026 deadline?
Yes, and the same deadline applies. A spousal RRSP lets the higher-earning spouse contribute and claim the deduction, while the lower-earning spouse owns the account and eventually withdraws it at their lower marginal rate. The contribution still uses the contributor’s room, not the spouse’s.
Watch the three-year attribution rule: if your spouse withdraws within three calendar years of your last contribution, the withdrawal gets taxed back in your hands.
I got a bonus in February 2026 — can I contribute it for the 2025 tax year?
Yes, as long as it’s deposited into your RRSP by March 2, 2026, and you have the room. This is exactly what the 60-day window is designed for. When my mom asked me about this last year, she’d assumed bonus money had to go toward the year she received it — but the contribution date is what matters, not the income date.
Just confirm your 2025 contribution room on your Notice of Assessment first so you don’t accidentally cross into over-contribution territory.
Do employer RRSP matching contributions count against my $31,560 limit?
Yes. Both your contributions and your employer’s match count against your personal RRSP room for the year. Your T4 will show the employer portion in box 20 (RRSP contributions) and you’ll get a contribution receipt for it. If your employer matches 5% of a $90,000 salary, that’s $4,500 of your room used before you’ve added a dollar yourself.
What happens to my RRSP room if I move provinces or work abroad?
RRSP room is federal, so moving between provinces doesn’t change it. If you work outside Canada and stop earning Canadian-source income, you stop generating new room — but everything you’ve already accumulated stays. Existing contributions keep growing tax-deferred. If you become a non-resident, you generally can’t make new contributions, and withdrawals are subject to a 25% Canadian withholding tax (sometimes reduced by treaty).
