A Registered Retirement Savings Plan (RRSP) is a Canadian investment account that lets you save for retirement while paying less tax today. You contribute pre-tax dollars, your investments grow tax-free inside the account, and you pay tax only when you eventually withdraw the money, ideally in retirement when your income and tax rate are lower. That three-part cycle of deduction, tax-sheltered growth, and deferred taxation is the core of how an RRSP works.
The Tax Deduction Up Front
Every dollar you contribute to an RRSP can be deducted from your taxable income for the year. If you earn $80,000 and contribute $10,000, you’re only taxed on $70,000. The actual tax savings depend on your marginal tax rate. Someone in a 30% combined federal and provincial bracket would save roughly $3,000 in tax on that $10,000 contribution.
You don’t have to claim the deduction in the same year you contribute. If you expect your income to jump next year, you can make the contribution now and carry the deduction forward to use when it saves you more.
How Your Money Grows Inside the Plan
Once your money is in the RRSP, any investment income it earns, whether from interest, dividends, or capital gains, is exempt from tax as long as it stays in the plan. This matters more than most people realize. In a regular taxable account, you lose a slice of your returns to tax every year. Inside an RRSP, the full amount keeps compounding. Over 20 or 30 years, that uninterrupted compounding can add tens of thousands of dollars to your balance compared to holding the same investments outside the plan.
You can hold a wide range of investments in an RRSP: savings deposits, GICs, bonds, stocks, mutual funds, ETFs, and certain other qualifying investments. The RRSP itself is just the registered account. What you put inside it is up to you and your risk tolerance.
Contribution Limits
You can contribute up to 18% of your previous year’s earned income, subject to an annual dollar cap. For 2026, that cap is $33,810. So if you earned $120,000 in 2025, your limit is $21,600 (18% of $120,000). If you earned $250,000, you’d hit the $33,810 ceiling instead.
If you have a pension plan through your employer, something called a pension adjustment reduces your available RRSP room to account for the retirement benefits you’re already building. The CRA calculates your exact contribution limit each year and prints it on your Notice of Assessment after you file your tax return. You can also check it through your My Account on the CRA website.
Unused contribution room carries forward indefinitely. If you couldn’t afford to max out your RRSP five years ago, that unused space is still waiting for you. This is one of the plan’s most valuable features for people whose income rises over time.
Be careful not to over-contribute. You have a lifetime over-contribution cushion of $2,000, but anything beyond that is penalized at 1% per month on the excess amount until you withdraw it.
Withdrawals and Withholding Tax
When you take money out of your RRSP, the withdrawal is added to your taxable income for the year. Your financial institution also withholds tax at source before handing you the funds. The withholding rates for Canadian residents (outside Quebec) are:
- Up to $5,000: 10% withheld
- $5,001 to $15,000: 20% withheld
- Over $15,000: 30% withheld
That withholding is not necessarily your final tax bill. It’s a prepayment. When you file your return, the withdrawal gets taxed at your actual marginal rate. If your marginal rate is higher than the withholding percentage, you’ll owe more at tax time. If it’s lower (common in retirement), you may get some of the withheld amount back.
Early withdrawals are generally a bad deal. You permanently lose that contribution room, you trigger immediate tax, and you miss out on years of tax-sheltered growth. The plan is designed to reward patience.
Two Ways to Withdraw Without Penalty
The government created two programs that let you pull money from your RRSP for specific purposes without owing tax on the withdrawal, as long as you pay it back.
Home Buyers’ Plan (HBP)
If you’re a first-time home buyer, you can withdraw up to $60,000 from your RRSP to put toward buying or building a qualifying home. No withholding tax applies. You then repay the amount back into your RRSP over a set number of years. If you miss a scheduled repayment, that year’s required amount is added to your taxable income.
Lifelong Learning Plan (LLP)
If you or your spouse enrolls in full-time education or training at a qualifying institution, you can withdraw up to $10,000 per year, to a maximum of $20,000 total. Like the HBP, you repay the borrowed amount over time, and missed repayments become taxable income.
What Happens at Retirement
By December 31 of the year you turn 71, you must close your RRSP. You have three options at that point:
- Convert to a RRIF: A Registered Retirement Income Fund works like an RRSP in reverse. Your investments stay tax-sheltered, but you must withdraw a minimum amount each year. Most retirees choose this option because it lets them draw income gradually.
- Buy an annuity: You hand a lump sum to an insurance company, and they pay you a guaranteed income stream for life or for a set number of years.
- Withdraw everything: You can cash out the entire RRSP. The full amount is added to your income for that year, which could push you into a very high tax bracket. This is rarely the best choice.
You can also use a combination of these options. Many people convert most of their RRSP to a RRIF while using a portion to purchase a small annuity for guaranteed baseline income.
Who Benefits Most From an RRSP
The RRSP is most powerful when your tax rate at the time of contribution is higher than your tax rate at the time of withdrawal. That’s the classic retirement scenario: you earn a good salary during your working years, deduct contributions at a high rate, then withdraw in retirement when your income is lower.
If you’re currently in a lower tax bracket and expect your income to rise significantly, a Tax-Free Savings Account (TFSA) may be a better first choice, since TFSA withdrawals are completely tax-free regardless of your future income. Many Canadians benefit from using both accounts strategically. Contribute to your RRSP when your income is high to capture the bigger deduction, and use your TFSA when your income is modest or when you’ve maxed out your RRSP room.
How to Open an RRSP
You can open an RRSP at virtually any bank, credit union, online brokerage, or investment firm in Canada. You need a valid Social Insurance Number and you must have earned income that generates contribution room. There is no minimum age to open an account, though you need earned income to build room, and the account must be closed by the end of the year you turn 71.
Setting up automatic contributions, even small ones, is one of the simplest ways to build the habit. A $200 biweekly contribution adds up to $5,200 a year, and the tax refund it generates can be reinvested to accelerate your savings further.
