RRSP Optimizer (2026)

For 2026, you can contribute up to 18% of your prior year's earned income, capped at $33,810. Unused room from previous years carries forward indefinitely. Your exact number is on your latest Notice of Assessment.

March 1, 2027 is the deadline for contributions you want to deduct on your 2026 tax return. Contributions in the first 60 days of the following year can be applied to either tax year — useful for bracket optimization.

Each dollar of RRSP contribution gives back a refund at your marginal tax rate. As your income drops past a bracket boundary (e.g., from 33% federal down to 29%), the next dollar refunds less. The bracket-optimal contribution is the amount that drops you down exactly to the next-lower bracket — past that point, you're "wasting" deduction room at a lower refund rate.

Generally: RRSP if your current marginal tax rate is higher than your expected retirement rate (typical for high earners during peak career). TFSA if you expect equal or higher tax rates in retirement. Many Canadians use both — RRSP for the refund, then plow the refund into the TFSA.

Yes. Contributing to your RRSP and deducting it in the same year is the default, but you can hold the deduction for a future year — useful if you expect to be in a higher bracket later (e.g., promotion next year). The contribution still reduces room immediately.

If you withdrew from your RRSP under the HBP, you have 15 years to repay it back to your RRSP. The minimum annual repayment counts as a contribution but doesn't add deduction room. Each year, your "effective deductible" room is your normal room minus the HBP minimum repayment. The full Abaq app surfaces this automatically; this public calculator estimates your basic room only.

CRA allows a $2,000 lifetime over-contribution buffer with no penalty (but no deduction). Anything beyond is taxed at 1% per month. The annual statement of RRSP deduction limit on your NOA is your authoritative number.
