An RRSP is a tax-advantaged account that allows your investments to grow without tax until you withdraw the money. Understanding contribution limits and how your tax bracket affects the benefit can help you keep more of your income while building long-term savings.
This guide covers how RRSPs work, what you can hold inside them, the rules around contributions and withdrawals, and how to decide whether an RRSP makes sense for you.
What is an RRSP?
An RRSP is a tax-advantaged retirement savings account that lets Canadians contribute pre-tax income, allowing investments to grow tax-deferred until withdrawal. When you contribute to an RRSP, you can deduct that amount from your taxable income for the year, which lowers your tax bill.
Any money that you earn inside your RRSP is also tax-deferred - your investments can continue to grow without being taxed until they are withdrawn/until withdrawal.
How does an RRSP work?
Your RRSP contributions lower your taxable income dollar for dollar. Let's say you make $70,000 per year and you decide to contribute the maximum allowable amount into your RRSP. Assuming you also made $70,000 the previous year and are up to date on your contributions, the most you can put in is 18%, or $12,600. When tax day comes around, the Canada Revenue Agency (CRA) will treat your income as though you only earned $57,400 and your payable taxes will be assessed accordingly.
Keep in mind that RRSP growth is tax-deferred, not tax-free. You will pay tax when you withdraw funds later, but by the time you do so, you may be retired, and your taxable income could be lower than it is during your working years. Lower income in retirement could mean a lower tax rate.
RRSP investment options
An RRSP is not an investment itself — it's a tax-advantaged container that holds your investments. Think of it like a basket. What you put inside that basket is largely up to you.
You can hold a wide variety of qualified investments inside an RRSP, including:
Individual stocks
Exchange-traded funds (ETFs)
Mutual funds
Bonds
Guaranteed investment certificates (GICs)
Cash
The right mix depends on your timeline and risk tolerance. Because RRSPs are designed for long-term retirement savings, many people choose investments that can grow over decades.
What is the maximum RRSP contribution?
Your annual RRSP contribution limit is based on two main factors:
Income-based calculation: You can contribute up to 18% of the income you reported on your previous year's tax return, up to the annual maximum of $33,810 (2026).
Unused contribution room: Unused contribution room from previous years carries forward, which can let you catch up on missed contributions.
For example, if you have $10,000 of extra contribution space from previous tax years, you can contribute that amount on top of your current year's limit.
Who can contribute and when
To contribute to an RRSP, you need:
A valid Social Insurance Number (SIN)
Earned income reported on your tax return
Canadian tax residency
There's no minimum age to open an RRSP, but there is a maximum. You can contribute until December 31 of the year you turn 71. After that, you must close the RRSP and convert it to a RRIF, purchase an annuity, or withdraw the funds.
RRSP withdrawal rules and taxes
Withdrawals from an RRSP are added to your taxable income for the year and taxed at your marginal rate.
When you make a withdrawal, your financial institution withholds a portion and sends it directly to the government. The withholding tax rate depends on the amount you withdraw:
Withdrawal amount | Withholding tax rate (most provinces) |
|---|---|
| Up to $5,000 | 10% |
| $5,001 to $15,000 | 20% |
| Over $15,000 | 30% |
At tax time, if your actual tax rate is higher than what was withheld, you'll owe the difference. If it's lower, you might get a refund.
It's also important to know that when you withdraw money from an RRSP, you lose that contribution room forever. You generally cannot re-contribute withdrawn amounts to restore RRSP contribution room. (Unlike a TFSA, withdrawals do not create new contribution room.) There are exceptions, such as the Home Buyers' Plan (HBP) and the Lifelong Learning Plan (LLP), which let you withdraw funds and avoid immediate tax if you repay the required amounts within the timelines.
RRSP pros and cons
Here are the main advantages and drawbacks of using an RRSP:
Pros:
Contributions can lower your taxable income for the year, which may lead to a refund.
Investments can grow tax-deferred, meaning you do not pay tax on capital gains or dividends while the funds remain in the RRSP.
You may be able to withdraw funds through specific programs (such as the Home Buyers' Plan or Lifelong Learning Plan) and avoid immediate tax if you follow the repayment rules.
Cons:
Withdrawals are fully taxed as income, which can be costly if you take money out during your peak earning years
Once you withdraw funds, you lose that contribution room permanently
You are required to convert the account and start taking minimum withdrawals the year you turn 71, whether you need the money or not
RRSP vs TFSA
A Tax-Free Savings Account (TFSA) is another registered account Canadians can use to save and invest. RRSPs and TFSAs are both tax-advantaged savings accounts, but they work differently:
Feature | RRSP | TFSA |
|---|---|---|
| Contributions | Tax-deductible (lowers current tax bill) | Not tax-deductible |
| Growth | Tax-deferred | Tax-free |
| Withdrawals | Fully taxed as income | Tax-free |
| Better for | Higher earners (over $50,000/year) | Lower earners or flexible savings goals |
TFSAs often make more sense if you earn less than $50,000 per year, since you likely don't owe much income tax anyway. Learn more about choosing between these accounts.
How do I open an RRSP in Canada?
You have a few options for opening an RRSP:
Through your employer: Many employers offer Group RRSPs, which automatically deduct contributions from each paycheque
At a financial institution: You can open an RRSP independently and choose your own investments or have them managed for you
If you open your own RRSP, you'll need to link a chequing or savings account and make contributions yourself. Setting up automatic deposits can help you save consistently.
How much should I contribute to an RRSP each year?
The right contribution amount depends on your circumstances. First, confirm an RRSP makes sense for you compared to a TFSA, which we covered above.
If you can afford to contribute the maximum and won't need the money until retirement, that's often the ideal approach. Otherwise, balance how much you need today versus how much you'll need in the future.
One key consideration: if you have a Group RRSP and your employer matches contributions (usually 1% to 5% of salary), contribute enough to maximize that match. It's an additional employer benefit when you contribute enough to receive the full match.
Is there a penalty for over-contributing to an RRSP?
In general, the CRA allows a small buffer if you over-contribute—but only up to a point. They start you with a nice cushion: any amount up to $2,000 over your annual limit won't be penalized if you’re 18 or older in the affected tax year (though it also won't be considered tax-deductible). It's when you go over that amount that the trouble starts.
If you exceed the $2,000 buffer, the CRA may assess a 1% monthly penalty on the excess amount and may contact you about removing the over-contribution. If you do not pay on time, additional interest and late-payment penalties may apply.
Fortunately, the CRA understands that mistakes happen. If you can show the over-contribution was unintentional—for example, due to a calculation error—and you take steps to correct the error, you may be able to request relief from the penalties.
How to check your RRSP balance and contribution room
You can check your RRSP information in two places:
Your financial institution's platform: Log in to check your current balance and investment performance
CRA My Account: View your remaining contribution room, RRSP deduction limit, and get alerts if you've over-contributed
