Physician incorporation in Quebec: when and how

By the JeanKali Santé CPA team · Published October 24, 2026 · 4-min read · Resources

In Quebec, physicians can practise through a business corporation, usually called a medical professional corporation. It's an important decision: used well, it defers tax and gives you more control over how you pay yourself; set up at the wrong time, it mostly adds cost and paperwork. Here is how we approach it with our clients, using the rules in force in 2026.

1. What incorporating does, and what it doesn't

The main benefit is simple: professional income earned by the corporation is taxed at a lower rate while it stays in the corporation. You pay personal tax only when you take a salary or dividends. If you spend nearly everything you earn each year, most of that gap disappears, because the money leaves the corporation as soon as it is earned.

Incorporating also doesn't turn a salary into business income. If you are paid as an employee of an institution (for example during residency), that salary generally can't be redirected to your corporation.

2. Corporate tax rates in 2026

Federally, the net tax rate is 15% on general business income and 9% on income eligible for the small business deduction (SBD) of a Canadian-controlled private corporation, according to the Canada Revenue Agency.

In Quebec, the general rate is 11.5%. Quebec's SBD lowers the rate to 3.2% on the first $500,000 of eligible income, and to 2.2% for taxation years that begin after April 29, 2026, according to Revenu Québec and the Ministère des Finances information bulletin 2026-3.

One Quebec-specific point matters a lot: to claim Quebec's SBD, a corporation that isn't in the primary or manufacturing sector must meet the paid-hours test, meaning at least 5,500 paid hours in the year (or in the previous year together with associated corporations). The deduction shrinks on a straight line between 5,500 and 5,000 hours and disappears at 5,000 hours or less. A physician alone in a corporation with no employees often doesn't qualify in Quebec, while still keeping the federal SBD. We run this test case by case, because special rules apply to the shareholder's own hours.

Finally, the $500,000 business limit is reduced when the corporation and its associated corporations earn more than $50,000 of passive investment income, and it is eliminated at $150,000 (CRA; Revenu Québec). Building a large portfolio inside the corporation needs a plan.

3. The Collège des médecins rules

Practising through a corporation is governed by the Regulation respecting the practice of medicine within a partnership or a joint-stock company (CQLR, c. M-9, r. 21). In short:

• all voting rights must be held by one or more physicians (or by a qualifying company or trust they control);
• other people can hold non-voting shares, including the spouse, relatives or in-laws of a physician shareholder, within the limits of the regulation;
• directors must be physicians, and the articles must set out these conditions;
• before practising through the corporation, each physician needs the Collège's authorization: the request is made online, costs $500 per physician and takes about 14 business days (cmq.org);
• compliant liability coverage is required: CMPA members are covered automatically; others need excess coverage from their insurer.

4. RAMQ payments to your corporation

Once the corporation is authorized, RAMQ can pay your fees to the corporation instead of to you personally. To do this, the corporation opens a collective administrative account using form 4552; RAMQ indicates a processing time of 4 to 6 weeks (ramq.gouv.qc.ca). Plan for that delay so your fees aren't still being paid in your own name for a period. Non-RAMQ income (expert reports, teaching, non-insured services) is reviewed separately.

5. The steps, in order

1. Review of your numbers: expected income, personal needs, savings, family situation.
2. Incorporation with the Registraire des entreprises ($397 regular rate, plus $27 for a name reservation if needed, according to the Registraire's fees), with articles that meet the Collège's regulation.
3. Organization: resolutions, share issuance, minute book, initial declaration.
4. Proof of coverage, then the authorization request to the Collège.
5. Corporate bank account and the RAMQ collective administrative account.
6. Bookkeeping, payroll if needed, and your pay plan.

6. Salary, dividends and family

Salary creates RRSP room and QPP contributions; dividends don't. Most incorporated physicians use a mix, reviewed every year. As for dividends paid to family members, the tax on split income rules (TOSI, in force since 2018) sharply limit the benefit in most cases. Assess this before issuing shares to family.

7. Pros and cons

Pros

• Tax deferral on the income you leave in the corporation.
• Flexibility on when and how you pay yourself.
• A structure that can grow with you: holding company, shareholder agreement, estate planning with your advisers.

Cons

• Start-up and annual costs: bookkeeping, T2 and CO-17 returns, annual updates with the Registraire and the Collège.
• More administration: a separate bank account, payroll, T4/RL-1 or T5/RL-3 slips.
• Little benefit if you spend most of your income, and Quebec's SBD is often out of reach without employees.

8. So, when should you incorporate?

In practice, the right question isn't "are my colleagues incorporated?" but "how much will I leave in the corporation each year?". When your professional income clearly and consistently exceeds your personal needs, incorporating usually starts to make sense. We run the numbers with your real figures before recommending anything, and we tell you plainly when it isn't worth it. Still in residency? Read our guide for medical residents too.
