Project your RRSP at retirement, the lifetime tax you defer on contributions, and the after-tax value when you eventually draw it down. Combines your current and expected retirement marginal rates so the deferral math is honest.
Key takeaway
The RRSP is a tax-deferral tool, not a tax-elimination one. Contributions reduce taxable income today; withdrawals are fully taxed as ordinary income in retirement. The deferral wins when your retirement marginal rate is lower than the rate at which you contributed. Annual room in 2026 is 18% of last year's earned income or $32,490, whichever is less, plus unused carry-forward.
An RRSP isn't a tax-free account. It's a tax-deferred one. That distinction is the most important thing to understand before you contribute another dollar. You put pre-tax money in (or get a refund on after-tax dollars), the money grows untaxed inside the plan, and when you eventually pull it out it's taxed as regular income at your marginal rate that year. The whole strategy turns on one comparison: is your current marginal rate higher than the rate you'll face at withdrawal? If yes, the RRSP wins. If no, it's mathematically identical to a TFSA after tax. There's no magic here. Just timing.
This is the part most people forget. For a 35-year-old Canadian in tech making $150k, the combined marginal rate sits in the 43-50% range. In retirement, drawing $60-80k from RRIF + CPP + OAS, the marginal rate is more like 25-30%. That 15-20 percentage point spread is the actual benefit of an RRSP, and it's why "max your RRSP" is usually right for high earners and usually wrong for someone in their twenties earning $60k. Run your real numbers. The calculator below uses both your current and expected retirement marginal rates so the comparison is honest.
Your 2026 deduction limit is 18% of your 2025 earned income, capped at $32,490, plus unused room carried forward from prior years, minus any pension adjustment if you have a workplace pension. The exact figure is on your most recent CRA Notice of Assessment under "RRSP Deduction Limit." You can contribute more than you deduct in a given year (handy for catch-up scenarios), but contributing more than $2,000 over your limit triggers a 1% per month CRA penalty. That math gets ugly fast.

Yes, fully. The RRSP defers tax, it doesn't eliminate it. Every dollar you withdraw is added to your taxable income that year and taxed at your marginal rate. The strategy works when your retirement marginal rate is lower than your contributing-years marginal rate.
Roughly: RRSP wins when your current marginal rate is higher than your expected retirement marginal rate (typical for high earners 35+). TFSA wins when the reverse is true or when you'll need the money before retirement. Most Canadian millennials should use both, with the FHSA stacked on top if they're buying a first home.
No. You must collapse your RRSP by December 31 of the year you turn 71. The standard move is to convert it to a Registered Retirement Income Fund (RRIF), which then has mandatory minimum annual withdrawals. A spousal RRSP can extend contributions if your spouse is younger.
A spousal RRSP lets the higher-earning partner contribute (and claim the deduction) into the lower-earning partner's account. At withdrawal, the lower earner pays the tax. Less impactful than it used to be since pension income splitting became broadly available, but still valuable for couples with very different income trajectories or retiring before age 65.
