That is the answer for the 2026 tax year. It changes every year, and not the way most people assume: the rule is not "March 1", it is the sixtieth day.
To contribute to an RRSP and deduct it from your 2026 income, you have until Monday, March 1, 2027 inclusive. After that you can still contribute, but the deduction will count toward 2027.
The rule that produces that date is not "March 1". It is the sixtieth day following the end of the calendar year, moved to the next business day if it lands on a Saturday or Sunday. The 60th day after December 31, 2026 is March 1, 2027, a Monday: the date stands as is.
The distinction looks academic right up until it isn't. In a leap year February has 29 days and the deadline moves back a day: for the 2027 tax year it will be February 29, 2028. And when the 60th day falls on a weekend, it moves forward: the 2030 deadline slides to March 3, 2031.
Each row applies the same rule: 60 days after December 31, then pushed to Monday if that lands on a weekend. Two years out of seven do not fall on March 1.
| Tax year | 60th day | Actual deadline | Why |
|---|---|---|---|
| 2025 | Sunday, March 1, 2026 | Monday, March 2, 2026 | Pushed: the 60th day was a Sunday |
| 2026 | Monday, March 1, 2027 | Monday, March 1, 2027 | Business day, no shift |
| 2027 | Tuesday, February 29, 2028 | Tuesday, February 29, 2028 | Leap year: February has 29 days |
| 2028 | Thursday, March 1, 2029 | Thursday, March 1, 2029 | Business day, no shift |
| 2029 | Friday, March 1, 2030 | Friday, March 1, 2030 | Business day, no shift |
| 2030 | Saturday, March 1, 2031 | Monday, March 3, 2031 | Pushed two days: Saturday |
Dates computed from the 60-day rule, verified September 4, 2026. The countdown at the top of this page applies the same rule rather than a hard-coded date: it stays correct year to year without anyone touching it.
Most RRSP mistakes are not about the deadline itself. They are about a different deadline mistaken for it.
| Deadline | When | What it covers |
|---|---|---|
| RRSP contribution | 60th day, around March 1 | Putting the money in to deduct it from the previous year |
| Tax return | April 30 | Filing. June 15 if self-employed, but the balance is still due April 30 |
| FHSA contribution | December 31 | No 60-day window: a January contribution counts toward the new year |
| TFSA contribution | None | Room appears January 1 and carries forward with no time limit |
Verified September 4, 2026. These dates are set by rule and do not move year to year, except for the shift to the next business day.
The FHSA is the costliest one to confuse, because the mistake cannot be undone: unused room from a year only partly carries forward, and a January contribution made in the belief that it "catches up" the previous year catches up nothing. If you are still weighing the two plans, which one to fill first by income level settles it on a single number.
Your limit is 18% of your previous year's earned income, up to a dollar cap set each year, minus your pension adjustment if you have a workplace plan. Unused room carries forward indefinitely.
| Year | Dollar limit | Earned income needed to reach it |
|---|---|---|
| 2025 | $32,490 | $180,500 in 2024 |
| 2026 | $33,810 | $187,833 in 2025 |
| 2027 | $35,390 | $196,611 in 2026 |
Limits verified September 4, 2026. The income figure is the limit divided by 18%, rounded to the dollar. Your personal number is on your latest notice of assessment, and only that number governs: it accounts for your pension adjustment and carried-forward room.
To see what the contribution gives back rather than what it costs, the tax refund calculator runs the numbers for your province and income. That is usually where the contribution becomes real: the same $5,000 does not return the same amount at $45,000 of income as at $130,000.
A contribution paid between January 1 and the deadline sits in a special place: it must be reported on the previous year's return, on Schedule 7, even if you do not deduct it.
Reporting and deducting are two separate acts, and that is where the flexibility lives. You can enter the contribution without claiming it right away, then carry the deduction forward to a year when your marginal rate will be higher — after a raise, coming back from a leave, or the year an unusual payment pushes you into a new bracket.
Your contribution room does not evaporate on March 1. It carries forward indefinitely, and you can contribute the next day. What you lose is a year of timing: the contribution will count toward the current year, and the matching refund will arrive next spring rather than this one.
The only genuinely irreversible RRSP deadline is the one at 71. The plan has to be converted to a RRIF or an annuity by December 31 of the year of your 71st birthday, and that final contribution has no 60-day window: it is December 31, not the March 1 that follows. If your spouse is younger, a spousal RRSP stays open until December 31 of the year they turn 71.
If your RRSP is sitting elsewhere and you are using the season to move it, leave plenty of margin: a plan transfer takes weeks, not days, and it does not count as a contribution anyway.
