Canada gives savers two powerful registered accounts: the Registered Retirement Savings Plan (RRSP) and the Tax-Free Savings Account (TFSA). Both shelter investments from tax, but they shelter them differently — and the right choice depends on your income, your time horizon, and your retirement plans.
This guide compares the two head-to-head using current Canada Revenue Agency (CRA) rules and shows how to decide which to prioritise.
Quick Definitions
- RRSP — a tax-deferred account. Contributions reduce your taxable income today; withdrawals in retirement are taxed as income.
- TFSA — a tax-free account. Contributions are made with after-tax dollars; growth and withdrawals are fully tax-free.
Both are registered with the CRA and have annual contribution limits.
How Each Works
RRSP
- Contribution room (2024): 18% of prior-year earned income, up to $31,560, minus pension adjustments.
- Tax effect: contributions are deductible. A $10,000 RRSP contribution by someone in the 40% marginal bracket creates roughly $4,000 of tax savings in the year of contribution.
- Growth: tax-deferred while inside the account.
- Withdrawals: taxed at your marginal rate. Must convert to a RRIF or annuity by December 31 of the year you turn 71.
- Special programs: Home Buyers' Plan (up to $60,000 for first-time buyers) and Lifelong Learning Plan allow tax-free withdrawals if repaid.
TFSA
- Contribution room (2024): $7,000 annually. Cumulative room since 2009 (for anyone 18+ and resident throughout) is $95,000.
- Tax effect: contributions are NOT deductible.
- Growth: fully tax-free — interest, dividends, capital gains.
- Withdrawals: tax-free, do not count as income, do not affect OAS, GIS, or the Canada Child Benefit. Withdrawn amounts are added back to your room next calendar year.
Side-by-Side
| Feature | RRSP | TFSA |
|---|---|---|
| Tax on contribution | Deductible | After-tax |
| Tax on growth | Deferred | Tax-free |
| Tax on withdrawal | Marginal income tax | Tax-free |
| 2024 limit | 18% of income / $31,560 | $7,000 |
| Cumulative room | Indefinite carry-forward | Indefinite carry-forward |
| Withdrawal restores room | No (except HBP/LLP) | Yes, next calendar year |
| Affects income-tested benefits? | Yes (withdrawals) | No |
| Mandatory conversion | RRIF by 71 | Never |
The Core Decision Rule
If your marginal tax rate today is higher than the rate you expect in retirement → favour the RRSP.
If it is lower or similar → favour the TFSA.
This is the only rule that matters for most people, because both accounts produce mathematically identical after-tax growth if the tax rate is the same in both periods.
Worked Example
Maya earns $90,000 (Ontario marginal rate ≈ 31.5%). She has $10,000 to invest at 6% for 25 years.
- RRSP path: $10,000 grows to
$42,919; withdrawal taxed at 25% (assumed retirement rate) → **$32,189 after tax**. - TFSA path: $6,850 (the after-tax equivalent) grows to
$29,400; withdrawal tax-free → **$29,400**.
Because Maya's retirement tax rate is lower than her current rate, the RRSP wins. Project both with the RRSP Calculator and the TFSA Calculator.
When the TFSA Wins
- You are early-career with a modest income (marginal rate ≤ 25%).
- You are a high-income retiree whose RRSP withdrawals risk OAS clawback.
- You expect to inherit money or earn a much larger income later.
- You want flexibility — to buy a home, fund a sabbatical, or smooth income.
When the RRSP Wins
- You are in a high marginal bracket (40%+) now and expect a lower one in retirement.
- You want to use the Home Buyers' Plan.
- You receive an RRSP-matching employer contribution (treat as free money).
- You want to force long-horizon savings discipline — withdrawals carry a real tax cost.
Common Mistakes
- Treating the deduction as profit. It is a deferral, not free money. You will pay tax on the way out.
- Withdrawing from a TFSA and immediately recontributing the same year. This often triggers a 1%/month over-contribution penalty until January 1.
- Ignoring OAS clawback. Excess RRSP/RRIF income in retirement can claw back Old Age Security, indirectly taxing those withdrawals at well above the marginal rate.
- Splitting evenly without doing the math. Equal contributions are rarely optimal.
- Forgetting US-listed dividends. TFSAs do not shelter the 15% US withholding tax on dividends; RRSPs do (under the Canada-US tax treaty).
Frequently Asked Questions
Should I max one before the other? If unsure, max your TFSA first — its tax-free withdrawals provide unmatched flexibility, and it is harder to recover from an RRSP withdrawal mistake (lost room, taxed income).
What if I can only contribute a little? Lower-income earners (under ~$50k) almost always favour TFSAs because the RRSP deduction provides little benefit at low marginal rates.
Can I hold the same investments in both? Yes. Stocks, ETFs, mutual funds, bonds, GICs and cash all qualify in both accounts.
Are RRSP and TFSA the only registered accounts? No. Canada also offers the FHSA (First Home Savings Account), RESP, and RDSP — each with specific purposes.

Conclusion
The RRSP-vs-TFSA debate is really a question of tax-rate timing. Use the RRSP when your tax rate today is higher than in retirement; use the TFSA when it is not. For most Canadians, the right answer is both — and the right priority depends on income, employer matching, home-buying plans and whether you value flexibility or deduction.
