How the CRA formula works
New room = the lesser of 18% of your prior-year earned income and the annual dollar maximum ($33,810 for 2026), minus your pension adjustment.
Total room = new room + unused room carried forward (it never expires).
Earned income includes employment and self-employment income — not pensions, OAS, or investment income.
The RRSP contribution deadline for the 2026 tax year is March 1, 2027 (first 60 days).
Keep in mind
This is an estimate. Your official deduction limit is on your Notice of Assessment and in CRA My Account.
Tax saving shown assumes you claim the full deduction at your marginal rate this year.
