The RRSP Explained: How Registered Retirement Savings Plans Work

The Registered Retirement Savings Plan, or RRSP, is the backbone of retirement saving for most Canadians, and its logic is straightforward once you see the three stages. You deduct contributions from your taxable income today, your investments grow tax-deferred inside the plan, and you pay tax only when you withdraw, usually in retirement when your income and tax rate are lower. Your room is 18% of your prior-year earned income up to an annual maximum, which is $33,810 for 2026, and the plan must convert to a RRIF or annuity by the end of the year you turn 71.

This guide explains each stage, who the RRSP suits, and how it fits with your other accounts. It is written for working Canadians building toward retirement in Ottawa and across Ontario. Figures are current to the 2026 tax year.

The three stages: deduct, defer, withdraw

The RRSP offers a specific kind of tax advantage, and understanding the sequence is the key to using it well.

• Deduct: contributions reduce your taxable income in the year you claim them, which can generate a refund. A contribution claimed at a high marginal rate is worth more.
• Defer: inside the plan, investments compound without annual tax on interest, dividends, or gains, which accelerates growth over decades.
• Withdraw: when you take money out, the full amount is taxable as income. The RRSP does not eliminate tax; it defers it to a time you ideally control.

The strategy flows from this. The RRSP works best when your tax rate today is higher than the rate you expect when withdrawing. You deduct at a high rate and withdraw at a lower one, keeping the difference. This is why it suits higher earners and peak-income years, a theme we develop in RRSP contribution strategy.

How contribution room works

Your RRSP room for a year is 18% of your previous year’s earned income, up to the annual dollar maximum of $33,810 for 2026. From that, a pension adjustment is subtracted if you belong to a workplace pension plan, and unused room from prior years is added. The exact figure is printed on your CRA Notice of Assessment.

Two features deserve emphasis. First, unused room carries forward indefinitely, so you never lose it. Second, you do not have to claim the deduction in the year you contribute; you can carry it forward to a higher-income year when it is worth more. For the full calculation, including the pension adjustment, see how the RRSP contribution limit is calculated.

The RRSP versus the TFSA

The most common question is whether to favour the RRSP or the TFSA. The answer turns on your tax rate now versus later.

Consideration	Favours RRSP	Favours TFSA
Current income	High	Modest
Expected retirement income	Lower than now	Similar or higher
Need for flexibility	Lower	Higher
Income-tested benefits in retirement	Not a concern	A concern
Employer match available	Strongly favours RRSP	Not applicable

Neither is universally better; they serve different situations, and most people use both. Our fuller comparison in RRSP versus TFSA versus FHSA works through the choice, including where the FHSA fits for first-time buyers.

Special RRSP programs

The RRSP includes two programs that let you borrow from yourself:

• The Home Buyers’ Plan lets eligible first-time buyers withdraw from their RRSP toward a home, tax-free, provided the amount is repaid over a set number of years. Unrepaid amounts are added to income.
• The Lifelong Learning Plan lets you withdraw to fund education for yourself or your spouse, again with a repayment schedule.

Both are effectively interest-free loans from your own RRSP, and both must be repaid or the shortfall becomes taxable. For a first home, the RRSP Home Buyers’ Plan can be combined with the FHSA, and understanding how the FHSA works helps you use them together.

Withdrawals and the age 71 deadline

Outside the special programs, RRSP withdrawals are fully taxable in the year you take them, and the financial institution withholds tax at source. Because withdrawals add to your income, large or poorly timed ones can push you into a higher bracket or affect income-tested benefits, so they should be planned.

By the end of the year you turn 71, your RRSP must be converted to a Registered Retirement Income Fund or used to buy an annuity. A RRIF then requires a minimum taxable withdrawal each year, rising with age. You can no longer contribute to your own RRSP after conversion, though you may still contribute to a spousal RRSP if your spouse is younger. The conversion is a significant planning moment, covered in RRSP to RRIF conversion.

Investing within the RRSP

An RRSP is an account, not an investment. Within it you can hold cash, GICs, bonds, mutual funds, ETFs, and more. Because the account shelters growth from annual tax, it is often a sensible home for interest-bearing investments that would otherwise be taxed at your full rate, a point explored in tax-efficient investing in Canada. As with any account, mutual funds held inside are not guaranteed and their values change, so the mix should reflect your time horizon and risk tolerance.

The RRSP at death

Because the RRSP defers tax rather than eliminating it, what happens at death deserves attention. In general, an RRSP can pass to a surviving spouse or common-law partner on a tax-deferred basis if they are named as the beneficiary, rolling into their own registered plan. This is one of the most valuable features of the account for couples, because it avoids a large tax bill at the first death.

Where there is no surviving spouse, the situation is different. The full value of the RRSP is generally included as income on the deceased’s final tax return, which can mean a substantial tax bill in a single year, often at the highest marginal rate. This is a key consideration in estate planning, and it is one reason some families use insurance or other strategies to cover the anticipated tax. The treatment of registered plans at death is explored further in tax on death in Canada, and it underlines why naming the right beneficiary is not a formality but a planning decision.

Over-contributions and timing

Like the TFSA, the RRSP penalises over-contributions, though it allows a small lifetime buffer, commonly cited as $2,000, that is not deductible but not penalised. Beyond that, excess contributions attract a monthly penalty until withdrawn or absorbed by new room. Separately, many Canadians treat the first 60 days of the year as an RRSP deadline, because contributions in that window can be deducted against the prior tax year. This gives useful flexibility, but it also causes confusion, so it is worth tracking which tax year a contribution is being applied to.

Who the RRSP suits

The RRSP is most valuable for people with meaningful earned income who are in a higher tax bracket now than they expect to be in retirement, and for anyone with an employer match. It is less compelling for those on modest incomes, who may prefer the TFSA to preserve flexibility and future benefit entitlement. For most households the honest answer is that the RRSP is one tool among several, and the art lies in how you combine it with the TFSA, the FHSA, and taxable accounts over a lifetime.

Next step

The RRSP is simple in structure but powerful when its timing is managed well: when to contribute, when to claim the deduction, how to withdraw, and when to convert.
