What is an RRSP?
If you are Canadian and earning a paycheque, you have probably heard someone tell you to “max your RRSP” before the March deadline. Good advice, usually, but the RRSP gets explained badly. Banks treat it like a magic tax refund machine. Reddit treats it like a trap. Neither framing is quite right.
The Registered Retirement Savings Plan is a CRA-registered account that lets you defer tax on money you set aside for retirement. Contribute, deduct from your income, grow investments tax-free inside the account, and pay tax when you withdraw. That is the whole mechanic. Everything else is detail.
This is the starting point. If you already know the basics and want the mental model that changed how I think about refunds, read Your RRSP Refund Isn’t Free Money next.
How an RRSP works, step by step
Here is the lifecycle in plain language.
1. You contribute. You deposit cash into an RRSP at your bank or brokerage. You can hold cash, GICs, ETFs, mutual funds, or other qualified investments inside the account.
2. You claim a deduction. When you file your taxes, you tell the CRA how much you contributed. That amount comes off your taxable income for the year. If you earned $90,000 and contributed $10,000, you are taxed as if you earned $80,000.
3. You get a refund (or reduced withholding). The deduction typically shows up as a tax refund after you file. If you are in a 30% marginal tax bracket, a $10,000 contribution generates roughly $3,000 back. That refund feels like a bonus. It is not. The government is buying a stake in your RRSP, and they collect their share when you withdraw. I break that down fully in Your RRSP Refund Isn’t Free Money. You can also get that co-investment monthly with a T1213 instead of waiting until tax season.
4. Your investments grow tax-free. Dividends, interest, and capital gains inside the RRSP are not taxed year to year. The full balance compounds without the drag you would face in a regular taxable account.
5. You pay tax on withdrawal. When you pull money out, the full amount counts as income. The CRA withholds tax at source and you settle the rest when you file. If you contributed at a 30% marginal rate and withdraw at 23% in retirement, you keep more than you put in after tax. If your rate is higher at withdrawal, the RRSP hurts relative to a TFSA.
When your marginal rate at contribution matches your marginal rate at withdrawal, the RRSP and TFSA produce the same after-tax result. Same dollars in, same dollars out. The RRSP just looks bigger on your statement because the government’s share is sitting in there too. I walked through the math with Taylor and Riley in RRSP is a TFSA in disguise.
Who should use an RRSP?
The RRSP shines when your income today is higher than you expect it to be in retirement. If your employer matches RRSP or DPSP contributions, max that first. For everyone else, the income-based priority list lives in TFSA or RRSP or Unregistered.
People with defined benefit pensions (government workers, teachers, military, police) should think carefully about RRSP contributions. Your pension already provides guaranteed retirement income, which means your retirement tax bracket may be higher than you expect. If your DB pension plus CPP and OAS will push you into a similar or higher bracket in retirement, the RRSP advantage shrinks or disappears entirely. In that case, the TFSA’s flexibility and tax-free withdrawals may serve you better. Do not assume your pension income will put you in a low bracket. Check the estimated annual pension amount from your employer and add CPP/OAS on top before deciding.
Contribution room: how much can you put in?
Your RRSP contribution room is based on earned income from the prior year.
For 2026, the formula is 18% of your previous year’s earned income, capped at $32,490. If you earned $100,000 in 2025, you get $18,000 in new room (18% of $100,000). If you earned $250,000, you still cap at $32,490.
A few rules worth knowing:
- Unused room carries forward. If you did not use all your room in past years, it accumulates. Many Canadians have tens of thousands in unused RRSP room sitting on their CRA account.
- Pension adjustments reduce room. If you have a defined benefit or defined contribution pension through work, your RRSP room is reduced by a pension adjustment on your T4.
- Overcontributions are penalized. You can exceed your limit by $2,000 without penalty, but beyond that the CRA charges 1% per month on the excess.

How to open an RRSP
Any Canadian bank or discount brokerage can open one. Look for low fees and commission-free ETF purchases. I compared some options in Wealthsimple vs Questrade but the landscape changes frequently. What matters more than where you open it is that you actually open it.
What to invest in inside your RRSP
For most Canadians, the answer is a single all-in-one index ETF like VEQT, XEQT, VGRO, or XBAL. One fund, globally diversified, rebalanced automatically, MER around 0.25%. Pick a risk level and buy it. See What are all-in-one index funds for how to choose.
RRSP vs TFSA: when each wins
At equal marginal rates, the RRSP and TFSA produce the same after-tax outcome. I walked through the math in RRSP is a TFSA in disguise. For a practical priority list based on your income and goals, see TFSA or RRSP or Unregistered. Run your own scenario with the RRSP vs TFSA vs Unregistered calculator or plug your income into the Canadian Tax Calculator to see your marginal rate before you decide.
Special programs: HBP and LLP
Two programs let you borrow from your own RRSP without immediate tax. The Home Buyers’ Plan lets first-time buyers withdraw up to $60,000 per person toward a down payment, repaid over 15 years. Miss a repayment and that amount becomes taxable income. See What is the Home Buyers’ Plan for details. The Lifelong Learning Plan allows up to $20,000 ($10,000 per year) for full-time education, repaid over 10 years. Both are loans to yourself: repay or pay tax.
Withdrawals and what happens at 71
RRSP withdrawals are taxed as ordinary income, with tax withheld at source. Unlike a TFSA, withdrawn room is gone permanently, so do not treat your RRSP as an emergency fund. By December 31 of the year you turn 71, you must convert to a RRIF and take minimum annual withdrawals. You can withdraw earlier, and some people draw in low-income years before CPP and OAS to fill lower tax brackets.
What to do next
Use the RRSP when your tax rate today is higher than you expect in retirement, invest in low-cost index funds, and remember the refund is a partnership, not a gift. For deeper reading, start with Your RRSP Refund Isn’t Free Money and TFSA or RRSP or Unregistered. If you expect a higher tax bracket next year, read Should you defer RRSP deductions? before you claim. Run your numbers with the RRSP vs TFSA vs Unregistered calculator or Canadian Tax Calculator, then open an account and buy an index fund.
