The 2027 RRSP limit is $35,390 — and your 2026 deadline is March 1
The RRSP dollar limit rises $1,580 for 2027, but most people never hit it. What the 18% rule really gives you, what a deduction is worth at common incomes, and the dates that matter.
The CRA has already published next year's RRSP dollar limit: $35,390 for 2027, up $1,580 from $33,810 for 2026. It's a big number. For nearly everyone, it isn't the number that matters.
Your limit is the lesser of two things
Your RRSP room each year is 18% of last year's earned income, up to the dollar limit, plus any unused room carried forward. So:
- Your 2027 room is built from your 2026 earned income.
- To hit the full $35,390 you'd need about $196,600 of earned income in 2026. Most Canadians are nowhere near that.
- At $80,000 of earned income, the new room is $14,400 ($80,000 × 18%) — the dollar limit never comes into play.
Your exact room is on your last notice of assessment, or in CRA My Account. Pension adjustments from a workplace plan reduce it.
The headline limit is a ceiling. Your own room is 18% of income, so check your notice of assessment before planning a contribution.
What a deduction is actually worth
Every RRSP dollar you contribute is deducted at your marginal tax rate. Using Metrestick's 2026 Ontario numbers, the combined marginal rate is 29.65% at each of $60,000, $80,000 and $100,000 of income. That means:
| Contribution | Approx. tax saved (Ontario, $60K–$100K income) |
|---|---|
| $2,000 | $593 |
| $5,000 | $1,483 |
| $10,000 | $2,965 |
The rate differs by province and bracket, and drops once the deduction pulls part of your income into a lower bracket — so treat these as a good estimate, not a promise. You can see your own rate with the take-home pay calculator.
The dates that matter
- March 1, 2027 — the deadline to contribute and still deduct against 2026 income. It's the first 60 days of the year, not December 31.
- Any day in 2027 — contributions still count, but the deduction applies to your 2027 return.
- Turning 71 this year? Your RRSP has to close by December 31 — see our age-71 guide.
If you're deciding between waiting for March and contributing now, the tax saving is the same. Contributing earlier just gives the money more months to grow sheltered. If you contribute in January or February, you can still claim it on the 2026 return you file this spring.
The $2,000 cushion, and the trap beside it
The CRA lets you exceed your room by a lifetime $2,000 without penalty. Go beyond that and the tax is 1% per month on the excess. It's easy to trip if you contribute to both a workplace plan and your own RRSP, so check your room before a lump-sum deposit, not after.
Is the RRSP even the right account?
The deduction is most valuable when your income is high now and likely lower in retirement. If your income is modest, or you expect a big pension, a TFSA may serve you better — the logic is in our TFSA vs RRSP framework.
What to do this fall
- Find your 2027 room on your latest notice of assessment (and subtract any 2026 pension adjustment).
- Pick a contribution figure and a date — a monthly automatic transfer beats one panicked deposit in late February.
- Use the refund deliberately: debt, TFSA, or next year's RRSP.
