RRSP deadline 2026: You missed it, but here's what happens next

The 2026 RRSP deadline was March 2nd - what missing it costs and your options now.

The RRSP deadline for your 2025 tax return was March 2, 2026. If you're reading this in April, you missed it.

Missing the deadline doesn't kill your RRSP room - it just means you can't use last year's contribution space to reduce your 2025 taxes. That room rolls forward to next year, but the tax benefit doesn't.

Here's what that actually costs. Say you earned $80,000 in 2025 and live in Ontario. A $5,000 RRSP contribution would have put roughly $1,525 back on your tax return. Miss the deadline, make the same contribution in April, and you get nothing back until you file your 2026 return next year.

You're not just losing the refund timing - you're losing a year of compound growth on that refund money.

Your unused room doesn't expire

The CRA carries forward your unused RRSP room indefinitely. Check your most recent Notice of Assessment or log into your CRA account online - it'll show your total available room.

For 2025, your contribution limit was either $31,560 or 18% of your 2024 earned income, whichever was lower. If you didn't max that out, the unused space gets added to your 2026 limit of $33,810.

This means someone who's never contributed could have $65,370 in RRSP room available this year - last year's unused space plus this year's new room.

What to do now

Make your 2026 RRSP contribution early instead of scrambling next February. The contribution window for 2026 taxes runs from January 1, 2026 to March 1, 2027.

Contributing in April or May gives your money more time to grow before you get the tax refund next spring. At $80,000 in Ontario, TaxSplit.ca will show you exactly what that refund looks like - but it's roughly $1,525 per $5,000 contributed.

If you're debating between RRSP and TFSA, missing the deadline doesn't change the math. RRSP still usually wins above $60,000 income. Below that, TFSA first.

The catch: you can't fix last year's tax bill anymore. But you can avoid this scramble next year by contributing early in 2027 instead of waiting until the deadline.
