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 Withdrawn room comes back on January 1, not immediately.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.
