To deduct RRSP contributions on your 2026 tax return, you need to contribute by Monday, March 1, 2027.
The 2026 RRSP limit
Your 2026 deduction limit is 18% of your 2025 earned income, up to $33,810, plus any unused room carried forward, minus pension adjustments. Your exact number is printed on your Notice of Assessment and in CRA My Account.
Key dates
| Date | What |

| December 31, 2026 | Last day for TFSA contributions to count against 2026 room |

Over-contributing
You have a $2,000 lifetime buffer. Anything above your limit plus $2,000 is taxed at 1% per month.
Estimating your tax saving
A rough guide: your deduction × your marginal tax rate. For example, deducting $8,000 at a 30% marginal rate saves about $2,400. Your actual refund depends on your whole return.
