Understanding RRSP Contribution Limits
A beginner's guide to how contribution room is generated, calculated, and carried forward.
Your RRSP contribution limit (or 'room') is the maximum amount you can put into your Registered Retirement Savings Plan each year. This is one of the most powerful tax-saving tools in Canada, as every cent contributed is tax-deductible.
1
How Room is Generated
New room is created based on your earned income from the previous year.
Calculation: 18% of your earned income from the previous year.
Annual Cap: For 2025, the maximum new room is $32,490.
Pension Adjustment: Box 52 on your T4 reduces your available room.
2
Tracking Your Room
The CRA tracks your limit exactly, so you don't have to guess.
Notice of Assessment (NOA): Your limit is printed here every year.
CRA My Account: The most up-to-date source for your contribution room.
Carry Forward: Unused room from previous years rolls over indefinitely.

Over-contribution Rules
Contributing too much can lead to penalties.
Lifetime Buffer: You have a $2,000 accidental over-contribution grace amount.
1% Penalty: Any amount above the buffer is taxed at 1% per month.
Deduction Timing: You can contribute now but save the deduction for a higher-income year.
