RRSP vs TFSA: which should you use first?
Both shelter investment growth from tax. They differ on when you get the break — and that difference decides which one to fill first.
Use an RRSP when your tax rate today is higher than it will be when you withdraw — typically in your peak earning years. Use a TFSA when your rate today is low, when you may need the money back, or when you want withdrawals that do not reduce income-tested benefits. Most people should use both.
The whole comparison is one question: which rate is higher?
An RRSP gives you a deduction now and taxes the withdrawal later. A TFSA gives no deduction and never taxes anything. If your marginal rate were identical at contribution and withdrawal, the two would produce the same after-tax result. They differ because rates differ across a lifetime. Contributing at a high rate and withdrawing at a low one means the RRSP deduction was worth more than the eventual tax — that is the gain. Contributing at a low rate and withdrawing at a high one reverses it, and the TFSA would have been better. So the practical rule is about timing, not product: RRSP in your high-earning years, TFSA when your income is low or uncertain.
The benefit clawback most people miss
RRSP and RRIF withdrawals are income. That means they count toward the thresholds for Old Age Security recovery tax, the Guaranteed Income Supplement, the age credit and provincial income-tested programs. TFSA withdrawals are not income and count toward none of it. For someone whose retirement income will sit near a clawback threshold, that difference can be worth more than the original deduction — which is why a TFSA is often the better account for a modest-income retiree even though the deduction looks attractive today.
Practical order for most people
- Employer pension or RRSP matching first — that is a guaranteed return no account structure beats
- TFSA next while your income is low, and for money you may need before retirement
- RRSP once you are in a higher bracket, especially if it drops you below a benefit threshold
- Keep an emergency fund in the TFSA, never the RRSP — withdrawing from an RRSP costs the room permanently
Side by side
| RRSP | TFSA | |
|---|---|---|
| Contribution | Deductible from income in the year claimed | Not deductible; funded with after-tax money |
| Growth inside the account | Untaxed while it stays in | Untaxed, permanently |
| Withdrawal | Fully taxable as income, with withholding tax at source | Entirely tax-free |
| Effect on income-tested benefits | Withdrawals count as income and can claw back OAS and GIS | Withdrawals are not income and affect nothing |
| Room after withdrawal | Gone permanently (except HBP and LLP) | Restored — but only on January 1 of the next year |
| Age limit | Must convert to a RRIF or annuity by the end of the year you turn 71 | None |
| Best used for | Retirement, when your rate will be lower | Anything, including goals before retirement |
Which one fits you

High-income years, long horizons to retirement, and situations where the deduction reduces income below a benefit or credit threshold.
TFSA
Lower-income years, money that may be needed before retirement, and retirees whose income sits near a clawback threshold.
