Neither account is “better.” The RRSP usually wins when your practice income is high now and will be lower in retirement, because the deduction saves tax at today’s rate. The TFSA wins when you’re early in practice or your income swings, because you can pull money out without a tax bill. Most established clinicians should be funding both.
You don’t have a pension. These two accounts are it.
A hospital physio has a pension quietly building in the background. You don’t. When you run your own practice, nobody is saving for your retirement except you. That’s as true for an HST-exempt physiotherapist as it is for an RMT charging 13% on every treatment.
That raises the stakes. For an employee, RRSP vs TFSA is a nice-to-solve puzzle. For a self-employed clinician it’s the whole retirement plan, and picking the wrong account for a decade costs real money.
How each account treats your money
Deduct now, pay tax later
Contributions come off your taxable income. Investments grow untaxed, but every dollar you withdraw is taxed as regular income.
No deduction, never taxed again
You contribute after-tax dollars and get no deduction, but all growth and every withdrawal is completely tax-free.
The 2026 numbers: RRSP room is 18% of last year’s earned income to a maximum of $33,810, and your net self-employment income counts as earned income. TFSA room is $7,000 for 2026, and if you’ve been 18 or older since 2009 and have never contributed, you’re sitting on $109,000 of room.
Unused room in both accounts carries forward and doesn’t expire.
The bracket math that makes the RRSP work
An RRSP is a bet that your tax rate today is higher than your tax rate in retirement. Contribute $10,000 while your top dollars are taxed around 43% in Ontario and the deduction puts roughly $4,300 back in your pocket. Draw that money out in retirement at a 25% average rate and you keep the difference. If you don’t have a feel for your own marginal rate, our guide on how much to set aside for taxes walks through it.
Here’s a move most self-employed clinicians miss: you don’t have to deduct a contribution in the year you make it. If this year’s profit is modest but next year looks big, you can contribute now, let it grow, and carry the deduction forward to the higher-income year. The same deduction is worth far more against a 43% bracket than a 24% one.
One thing the RRSP won’t do is shrink your CPP bill. Self-employed CPP is calculated on your net business income before RRSP deductions, so the contribution trims income tax only.
And that spring refund isn’t free money.
It’s tax deferred, not tax erased. CRA collects its share when the money comes back out, which is exactly why the deduction should be spent at the highest bracket you can manage.
Why the TFSA fits a clinician’s income swings
Practice income isn’t a salary. A parental leave or a slow first year can cut your income in half, and this is where the TFSA earns its keep. Pull $15,000 from a TFSA in a rough year and it adds nothing to your taxable income. Pull the same amount from an RRSP and it’s taxed as income, and that contribution room is gone for good.
TFSA room comes back. Withdraw in November and the amount gets added to your room the following January 1. Just don’t re-contribute it in the same calendar year unless you have unused room left, because that mistake runs a penalty of 1% per month on the excess.
TFSA withdrawals are also invisible to income-tested programs. They won’t reduce the Canada Child Benefit today or trigger OAS clawback later, while RRSP and RRIF withdrawals count as income for both.
Incorporated? The order changes
Once your practice runs through a corporation, salary creates RRSP room and dividends don’t. That single fact shifts the retirement plan, and it’s one of the bigger inputs in the salary vs dividends decision. The corporation itself can also hold investments, a third bucket with its own tax rules, which we touch on in whether health practitioners should incorporate.
If you’re incorporated or about to be, don’t copy a sole proprietor’s savings order. The math is genuinely different.
