What is an RRSP, and how does it work? A beginner's guide

How is your RRSP deduction limit calculated?

RRSPs explained simply: a registered retirement savings plan is a retirement savings plan that you establish, the Canada Revenue Agency (CRA) registers, and to which you or your spouse or common-law partner contribute. Deductible contributions can reduce your tax. Income earned inside the plan is usually exempt from tax while the funds remain there, and you generally pay tax when you receive payments from the plan.

Your yearly contribution room is not a single flat number for everyone. The CRA generally calculates your RRSP deduction limit as unused room from the end of the preceding year, plus the lesser of 18% of your previous year's earned income and the annual RRSP dollar limit, then adjusts for pension adjustments. For 2025 the annual dollar limit is $32,490; for 2026 it is $33,810, as published in the CRA's MP, RRSP, DPSP and TFSA limits table.

The CRA says your RRSP deduction limit is the maximum you can deduct for contributions to your RRSPs, PRPP, SPP and your spouse's or common-law partner's RRSP or SPP for a year.

In practice the formula is: unused RRSP deduction room at the end of the preceding year, plus the lesser of 18% of earned income in the previous year and the annual RRSP limit, minus your pension adjustment (or prescribed amount for connected persons), plus any pension adjustment reversal, minus any net past service pension adjustment.

Worked illustration using the published 2026 dollar limit: if your 2025 earned income was $80,000 and you have no pension adjustment or unused room, 18% of $80,000 is $14,400. That is less than the $33,810 annual limit, so your new room for 2026 would be $14,400 before any unused room from earlier years is added.

Another illustration: earned income of $200,000 in 2025 produces 18% equal to $36,000, but the annual dollar limit caps new room at $33,810 for 2026. A workplace pension adjustment would reduce that further.

Readers evaluating RRSPs should separate marketing claims from the actual rule text that governs their account or product. When two summaries disagree, the governing document or statute wins. If a rule depends on your age, filing status, or income band, re-check it when any of those facts change. Life events quietly move people across thresholds they last reviewed years earlier.

Educational explainers like this one cannot replace personalized advice for complex situations such as divorce orders, inherited accounts, or cross-border tax residency. Escalate those cases to a qualified professional. When in doubt about a number that changes every year, describe your plan qualitatively first, then look up the current official figure for the tax year you care about before you act.

What happens if you contribute too much?

The CRA says that generally you have to pay a tax of 1 percent per month on contributions that exceed your RRSP deduction limit by more than $2,000. That $2,000 cushion is not extra deductible room; it only limits the monthly penalty tax.

Amounts you transfer directly into an RRSP (for example certain retiring allowances) do not use up your deduction limit in the same way as new contributions, but special reporting rules apply. Administration fees, brokerage fees inside a trusteed RRSP, interest on money borrowed to contribute, and capital losses inside the plan are not deductible contributions.

If you have unused contributions from a previous year, you can often deduct them in a later year when you have room. Check your RRSP deduction limit statement before you top up near the March deadline.

A useful habit is to write down your goal, time horizon, and cash buffer before you change any election related to RRSPs.

How do withdrawals and age 71 work?

Any income you earn in the RRSP is usually exempt from tax as long as the funds remain in the plan. The CRA says you generally have to pay tax when you cash in, make withdrawals, or receive payments from the plan. Locked-in RRSPs usually cannot be withdrawn freely; ask your issuer if you are unsure.

A direct transfer from one RRSP to another is a transfer, not a withdrawal. Special programs such as the Home Buyers' Plan and the Lifelong Learning Plan let you withdraw under conditions that are different from a regular cash-out; those rules are covered on the CRA's RRSP related-plans pages.

By the end of the year you turn 71 you must convert the RRSP, typically into a Registered Retirement Income Fund (RRIF) or an annuity, or withdraw the funds (which is taxable). The CRA also describes advanced life deferred annuity options that can defer income further in some cases.

Keep digital and paper copies of confirmations after every change. Screenshots of election pages, email receipts, and year-end statements make tax season and job changes far less chaotic. Compare fees the same way you would compare two similar listings before you buy: look at what you pay each year, what you get, and whether a simpler option meets the same need.

Automation helps. Calendar reminders for annual reviews, automatic transfers, and beneficiary checkups reduce the chance that a good plan dies from neglect.

How does an RRSP compare with a TFSA or a pension?

An RRSP gives a deduction now and taxable withdrawals later. A TFSA does not give a deduction, but qualifying withdrawals are tax-free and the room returns. For a side-by-side educational comparison, see and

If you already have a workplace pension, your pension adjustment reduces RRSP room, which is why two people with the same salary can have very different RRSP limits. Read for how public pensions fit the picture.

Spousal RRSPs can help couples whose tax rates differ, because the contributor claims the deduction while the spouse is the annuitant, subject to attribution rules on early withdrawals.
