Your RRSP contribution limit for 2026 is 18% of your 2025 earned income, up to a maximum of $33,810 - minus any pension adjustment (PA) from your employer's pension plan, plus any unused contribution room from previous years. RRSP room builds at 18% of your earned income each year. If you don't contribute in a given year, that room carries forward indefinitely. CRA allows a $2,000 over-contribution buffer. Beyond that, you'll pay a penalty of 1% per month on the excess amount. RRSP contributions for the 2025 tax year must be made by March 2, 2026. You can contribute to a spousal RRSP using your own contribution room. The contribution is deductible on your return, but the funds belong to your spouse.
