RRSP vs TFSA in Canada: Which Should You Fill First?

Canadians have two excellent tax-sheltered accounts and one persistent question. The answer hangs on a single comparison: your marginal tax rate today versus your expected rate in retirement. Get that one judgement roughly right and the rest is mechanics.

The one-line decision rule

• Higher tax bracket now than in retirement → RRSP first. You deduct at today's high rate and withdraw at tomorrow's lower one — the spread is your win.
• Lower bracket now (early career, variable income) → TFSA first. Pay today's low tax, then never pay tax on the growth. Save the RRSP deduction for higher-earning years — the room carries forward.
• Similar rates both ends → roughly a tie on the math; the TFSA wins on flexibility, the RRSP wins on forced discipline.

How the two accounts compare

	RRSP	TFSA
Contribution	Pre-tax (deduction now)	After-tax (no deduction)
Growth	Tax-deferred	Tax-free
Withdrawal	Fully taxable as income	Tax-free, any time, any reason
Room	18% of earned income to an annual cap; carries forward	Fixed annual amount for every adult; carries forward; withdrawals restore room next year
Affects benefits?	Withdrawals can claw back OAS/GIS in retirement	No — withdrawals don't count as income
Special programs	Home Buyers' Plan, Lifelong Learning Plan	—

The traps people actually fall into

• TFSA over-contribution: re-contributing a withdrawal in the same calendar year can exceed your room — the penalty is 1% per month on the excess. Withdrawn room comes back on January 1, not immediately.
• RRSP as an emergency fund: withdrawals are taxed at your full marginal rate, withholding applies up front, and the room is gone forever. Use the TFSA for accessible savings.
• Taking the deduction in a low-income year: you can contribute now and defer the deduction to a higher-bracket year — many people don't realise the two are separable.
• Ignoring the employer match: if your employer matches Group RRSP contributions, that match beats every other consideration — take it first.

The numbers for 2026

• TFSA: $7,000 of new room for 2026, and $109,000 cumulative if you were 18 in 2009 and have never contributed. Withdrawn room returns the following January.
• RRSP: 18% of prior-year earned income, capped at $33,810 for 2026, less any pension adjustment.

Why the "which is better" question is usually the wrong one

An RRSP defers tax; a TFSA eliminates it. The RRSP wins when your marginal rate in retirement is lower than it is today, and the TFSA wins when it is the same or higher. For most people early in a career the TFSA is better and later the RRSP is, which is why the honest answer is to use both in sequence rather than to pick one.

The benefit-clawback effect nobody models

This is where the real money is, and it is invisible in a simple tax comparison. TFSA withdrawals are not income, so they do not count toward the OAS recovery tax, the age credit, or income-tested provincial benefits. RRSP and RRIF withdrawals are fully taxable income and count toward all of them.

For a retiree near the OAS clawback threshold, drawing $10,000 from an RRSP instead of a TFSA can cost the 15% recovery tax on top of the marginal rate — an effective rate well above the headline bracket. Holding a TFSA balance into retirement is a tax-rate management tool, not just a savings account.

A practical order

1. Any employer RRSP match — it is an immediate return nothing else can beat.
2. FHSA, if a first home is plausible within 15 years: deductible in, tax-free out.
3. TFSA while your income and marginal rate are still rising.
4. RRSP once you are in a higher bracket than you expect in retirement.

Frequently asked questions

What are the 2026 RRSP and TFSA limits?
The TFSA annual limit is $7,000, with cumulative room of about $109,000 for someone eligible since 2009. The RRSP limit is 18% of prior-year earned income up to $33,810, plus any unused room carried forward.

Should I use an RRSP or a TFSA first?
It turns on your marginal rate now versus in retirement. Below roughly $55,000 of income the TFSA usually wins, because the RRSP deduction is worth little and withdrawals later could reduce income-tested benefits. Above that, the RRSP deduction becomes more valuable. Most people should eventually use both.

Does a TFSA withdrawal restore contribution room?
Yes, but not until 1 January of the following year. Withdrawing and re-contributing in the same calendar year is the most common TFSA over-contribution mistake, and the penalty applies monthly.

How do RRSP and TFSA affect government benefits?
RRSP withdrawals count as taxable income and can reduce OAS and other income-tested benefits, including triggering the OAS clawback. TFSA withdrawals do not count as income at all, which makes the TFSA particularly valuable for anyone likely to be near a benefit threshold in retirement.

Both interact with the OAS clawback, and so does the timing of your public pension — when to take CPP.
