RRSP vs. TFSA: where should your money go first?

It's the most common retirement question in Canada, and the most common wrong answer goes: "RRSPs, obviously — it's a tax deduction." Sometimes that's right. But the deduction is only half the story, and the other half — when the tax comes back — is what actually decides the answer.

The two tools, honestly described

• RRSP (Registered Retirement Savings Plan): you get a tax deduction when you contribute (useful when you're in a high bracket), the investments grow tax-shielded, and you pay income tax on what you withdraw in retirement.
• TFSA (Tax-Free Savings Account): no deduction when you contribute, the investments grow tax-free, and withdrawals are completely tax-free — including the growth.

Same dollar, two timing structures. One defers the tax; the other eliminates it. Which is better depends almost entirely on one variable:

The question that decides it: your tax bracket, now vs. later

If your income today is higher than your expected income in retirement — the classic case of a peak-earning professional planning to slow down — the RRSP deduction is worth real money right now, and you'll pay the tax back later at a lower rate. RRSP first is usually the efficient call.

If your income in retirement is expected to be the same or higher — for example, if your household keeps earning through retirement, or you have substantial taxable income from investments — the deduction is less valuable and the tax-free withdrawal is more valuable. TFSA first usually wins.

If you're young and in a lower bracket, the deduction is worth less today, which strengthens the TFSA case — with one important twist: employer matching. If an employer matches RRSP contributions, that's an immediate 50–100% return, and the RRSP wins outright for the matched amount, whatever the bracket math says.

The considerations the bracket math misses

• Home buying. The Home Buyer's Plan lets first-time buyers withdraw from an RRSP to buy a home and repay it over time. If you're within a few years of buying, an RRSP can serve a near-term purpose a TFSA can't.
• Room and limits. TFSA contribution room is annual, set by the government (indexed, and $7,000 in recent years), and unused room carries forward indefinitely. RRSP room grows with your earned income and carries forward too. In both accounts, contributing too much has real penalties — know your numbers before you fund up.
• Ordering matters more than exclusivity. "RRSP or TFSA" is the wrong frame for most people. The plan is usually: capture the employer match, fill whichever account's timing is more valuable this year, and keep both growing. A plan tells you the order; a guess doesn't.
• Provincial rates change the math. Deductions are worth more at higher marginal rates. Someone in a high-income province is more likely to benefit from the RRSP deduction than someone at the same income in a lower-rate province.

The account decision sits inside a bigger plan: your retirement income target, your CPP and OAS, and what the combined total produces. Work the numbers in the retirement calculator, then bring the whole picture to a conversation — the retirement planning guide covers how we build it.
