Your Registered Retirement Savings Plan (RRSP) contribution room determines how much you can contribute and deduct from your taxable income each year. Understanding how this room is calculated — and what happens when you exceed it — is fundamental to Canadian retirement planning.
How RRSP Contribution Room Is Calculated
Your RRSP deduction limit for a given year is generally 18% of your earned income from the previous year, up to the annual maximum. For 2026, the maximum is $32,490. If you have a pension adjustment (PA) from an employer pension plan, this reduces your room. Unused room carries forward indefinitely.
The RRSP Deadline
Unlike the TFSA which runs on a calendar year, the RRSP contribution deadline for a given tax year is typically 60 days into the following year (around March 1). Contributions made in the first 60 days of the year can be deducted on either the previous or current year's return.
Carry-Forward Room
Unused RRSP room from previous years carries forward with no expiry. If you earned room but did not contribute, that room accumulates. You can check your total available room on your CRA Notice of Assessment or through CRA My Account.
Over-Contribution Rules
The CRA allows a $2,000 lifetime over-contribution buffer without penalty. Beyond that, excess contributions are penalized at 1% per month on the excess amount. Over-contributions do not earn a deduction and the penalty can accumulate quickly.
Strategic Considerations
- You can contribute without deducting immediately — useful if you expect higher income in a future year.
- Spousal RRSP contributions use the contributing spouse's room but the plan belongs to the other spouse.
- RRSP withdrawals under the Home Buyers' Plan (HBP) or Lifelong Learning Plan (LLP) have repayment schedules.
- At age 71, your RRSP must be converted to a RRIF, annuity, or withdrawn.
