Plain English
The maximum amount you can contribute to your RRSP and deduct from your taxes. It's 18% of last year's income, up to a yearly cap set by CRA.
Technical definition
The RRSP deduction limit is calculated as 18% of the prior year's earned income, up to the annual dollar maximum, minus any pension adjustment, plus unused carry-forward room. The 2026 contribution dollar limit is $32,490 (based on 2025 earned income). Income earned in 2026 generates a $33,810 limit for 2027 contributions. The limit is confirmed on the Notice of Assessment.
Examples
- • You earned $100,000 in 2025. Your 2026 RRSP deduction limit is 18% × $100,000 = $18,000 (well under the $32,490 cap).
- • You earned $200,000 in 2025. 18% = $36,000, but the cap limits you to $32,490 in new room for 2026.
