Should your next dollar go into a TFSA or an RRSP?

Ask any Canadian money forum which to fill first, the Tax-Free Savings Account (TFSA) or the Registered Retirement Savings Plan (RRSP), and someone will say the RRSP refund barely covers a few grocery runs. Someone else puts every refund straight back in. Both are partly right, and both skip the part that decides it.

The TFSA vs RRSP choice is really about when you pay the tax. The TFSA takes money you have already paid tax on and lets it come out tax-free. The RRSP gives you a deduction now and taxes the money when it comes out. In the US, the same trade is the Roth vs traditional individual retirement account (IRA) decision.

The short answer: The RRSP tends to come out ahead when your tax rate today is higher than the rate you expect when you withdraw, and only if the refund is saved too. When that is not the case, the TFSA usually comes out ahead. For 2026 the Canada Revenue Agency (CRA) sets the TFSA limit at $7,000 and the RRSP limit at 18% of last year's earned income, up to $33,810.

TFSA vs RRSP: what actually differs

Four differences decide this choice.

• Tax in and tax out. RRSP contributions are deductible, and withdrawals are taxed as income. TFSA contributions "are not tax deductible," but what you put in and earn is "generally tax-free, even when you make a withdrawal," according to the CRA.
• How room builds. The TFSA dollar limit is the same for everyone who is eligible: $7,000 for 2026 (CRA limits). RRSP room is 18% of your previous year's earned income, capped at $33,810 for 2026, plus any unused room, and reduced by your pension adjustment if you belong to a workplace pension (CRA).
• Taking money out. When you withdraw from a TFSA, the CRA says you "regain the same amount as new available contribution room on January 1 of the following year" (CRA). RRSP room you withdraw is gone, apart from special programs such as the Home Buyers' Plan.
• An end date. In the year you turn 71, you must withdraw your RRSPs, move them to a registered retirement income fund (RRIF) or use them to buy an annuity (CRA). A TFSA has no end date.

An example: $1,000 and what happens to the refund

Take $1,000 of pay and a 30% marginal tax rate, federal and provincial combined. Assume the same investments double before you withdraw. The numbers are illustrative.

• TFSA: you pay the 30% first, so $700 goes in. It doubles to $1,400 and comes out tax-free: $1,400.
• RRSP, refund saved: the full $1,000 goes in, because the deduction gives the tax back. It doubles to $2,000. Taxed at 30% on the way out, you keep $1,400.

Same money. When your rate is the same at both ends, the accounts tie. Change only your rate at withdrawal and the winner changes: at 20%, the RRSP leaves $1,600, which is $200 more than the TFSA. At 40%, it leaves $1,200, which is $200 less.

Now the step most people skip. You put $700 in the RRSP, get a $210 refund and spend it. The $700 doubles to $1,400, and even at a lower 20% rate in retirement you keep $1,120. That is $280 less than the TFSA.

The RRSP only wins when the refund goes back to work, in the RRSP itself or in your TFSA.

Which should you fund first?

The Ontario Securities Commission's investor site puts the rule plainly: "An RRSP lets you defer taxes, which is an advantage if your marginal tax rate is lower in retirement" (GetSmarterAboutMoney).

Start with the TFSA if:

• Your income is modest. For 2026 the federal rate is 14% on the first $58,523 of taxable income, before provincial tax (CRA tax rates). The refund is small, and your unused RRSP room keeps building for higher-income years.
• You might need the money before retirement.
• You expect a high income in retirement, from a strong workplace pension for example. The same site says that if you expect a higher income after you retire, "the TFSA may be the better option."
• You may rely on income-tested benefits later. The CRA lists Old Age Security (OAS), the Guaranteed Income Supplement (GIS) and Employment Insurance among the benefits, and the Canada child benefit among the credits, that TFSA income and withdrawals do not affect. RRSP and RRIF withdrawals are reported as income, so they can.

Start with the RRSP if:

• You are in a higher bracket now than you expect to be in retirement. In 2026 the federal rate rises to 20.5% above $58,523 and 26% above $117,045, before provincial tax (CRA tax rates).
• You will save or invest the refund, not spend it.
• Your employer matches contributions to a group RRSP. A match is extra pay you only get if you contribute, so many people contribute at least enough to receive all of it.

Many households use both: RRSP contributions while income sits in a higher bracket, then the TFSA for the rest. One caution for larger savers: OAS is clawed back at 15% of net income above $95,323 for the 2026 income year (Government of Canada), and RRIF withdrawals count toward that income. TFSA withdrawals do not.

Where the FHSA fits if you're buying a first home

A First Home Savings Account (FHSA) gives you both tax breaks for one purpose. Contributions are "generally deductible," like an RRSP, and the account lets a first-time buyer "save to buy or build a qualifying first home tax-free (up to certain limits)" (CRA). Room starts at $8,000 a year, with a $40,000 lifetime limit (CRA).

For money you will put toward a qualifying first home, the FHSA is worth comparing first, because it combines a deduction going in with tax-free withdrawals for the home. The RRSP route still exists: the Home Buyers' Plan lets you withdraw up to $60,000 for a first home, but you repay it over 15 years (CRA).

Where to start this week

1. Log in to CRA My Account and note two numbers: your TFSA contribution room and your RRSP deduction limit.
2. Find your taxable income on last year's return and see which bracket it falls in.
3. Decide what the refund is for before it arrives: back into the RRSP, into the TFSA, or both.

If you have no savings cushion yet, a TFSA is a natural home for an emergency fund that fits your family, because you can take money out and put it back later.
