A professional corporation (PC) is a corporation that a regulated professional — a doctor, dentist, lawyer, accountant, engineer and others — uses to carry on their practice. In Alberta a PC is incorporated under the Business Corporations Act but must also be approved and permitted by the professional's regulatory body, and it is taxed like any other Alberta corporation: roughly 11% combined on the first $500,000 of active income and about 23% above that in the 2026 tax year. Crucially, a PC offers tax-deferral and some commercial liability protection, but it does not shield the professional from liability for their own professional negligence.
This guide covers who qualifies, how a PC is taxed, what it does and does not protect, and when incorporating is worth it.
Who can incorporate a professional corporation in Alberta
Not every profession can incorporate, and a PC is not a normal company you can simply register and start using. Two conditions apply:
- Your profession must be permitted to incorporate under its governing Alberta legislation.
- Your regulatory college must approve the corporation and issue a permit before it can practise.
Regulated professions in Alberta that may form professional corporations include, among others:
| Profession | Typical Alberta regulator |
|---|---|
| Physicians and surgeons | College of Physicians & Surgeons of Alberta |
| Dentists | Alberta Dental Association |
| Lawyers | Law Society of Alberta |
| Chartered Professional Accountants | CPA Alberta |
| Engineers | APEGA |
| Optometrists, chiropractors, psychologists, veterinarians | Respective Alberta colleges |
Each regulator sets its own rules on naming, share ownership, permits and renewals. You must hold a valid licence in good standing and obtain the regulator's permit for the corporation — the corporation cannot lawfully practise on the strength of the Alberta incorporation alone.
How a professional corporation is taxed in Alberta
A PC is taxed exactly like any other Alberta Canadian-controlled private corporation (CCPC). There is no special professional-corporation tax rate.
| Income type (2026 tax year) | Federal | Alberta | Combined |
|---|---|---|---|
| Active professional income up to $500,000 (SBD) | 9% | 2% | 11% |
| Active income over $500,000 | 15% | 8% | 23% |
The professional then pays personal tax on whatever they withdraw as salary or dividends. As with any incorporation, the benefit is deferral, not elimination: income left in the PC is taxed at ~11% now instead of up to ~48% personally, with the balance of tax paid when money is drawn out. Canada's integration system aims to make the total roughly neutral once income reaches your hands — so the real wins are deferral, income-smoothing across years, and the flexibility a corporation gives. Our salary vs dividends guide covers how professionals actually pay themselves.
Two CCPC rules apply equally to a PC:
- The $500,000 limit is shared among associated corporations.
- Passive investment income above $50,000 a year grinds the small-business limit down, eliminating it at $150,000 — relevant if a high-earning professional accumulates investments inside the PC.
What a professional corporation does — and does not — protect
This is the most misunderstood point. A PC provides the usual corporate liability shield against ordinary commercial obligations — supplier contracts, equipment leases, commercial debts. But it does not protect a professional against liability for their own professional negligence or malpractice. The regulator holds the individual personally accountable for the standard of their work, and that exposure is managed through professional liability insurance, not the corporation.
In other words: a PC is a tax and commercial-structuring vehicle, not a malpractice shield. Professionals still carry the insurance their college requires, regardless of incorporation.
Share ownership and income-splitting
Whether family members can own shares of your PC depends on your specific regulator, not on general corporate law. Some Alberta colleges require all voting shares to be held by licensed members of the profession; others permit family members to hold non-voting shares, which can support dividend income-splitting.
Even where the regulator allows family share ownership, the federal tax on split income (TOSI) rules limit when dividends to family members are taxed at their own (lower) rates rather than the top rate. So income-splitting through a PC is possible in some professions but is narrower than it once was, and must clear both the regulator's ownership rules and the TOSI rules. Check your college's requirements before relying on it.
Setting up an Alberta professional corporation
The mechanics layer a regulatory approval on top of the normal incorporation steps:
- Confirm eligibility and the regulator's rules — naming convention (often "Dr. Jane Smith Professional Corporation" or similar), permitted share structure, and shareholders.
- Incorporate provincially under the Alberta Business Corporations Act — a NUANS name report, Articles of Incorporation, registered office and agent for service. Our incorporate a business in Alberta guide covers these steps and costs (roughly $450–$650 all-in before professional and regulator fees).
- Apply to your regulatory college for a permit, paying its application and annual fees. The corporation cannot practise until the permit is issued.
- Set up the tax stack — Business Number, federal T2 and Alberta AT1 filings (each due within six months of year-end), GST registration once taxable revenue passes $30,000, and payroll if you take a salary.
When it makes sense
A professional corporation tends to pay off once your professional income reliably exceeds what you spend personally, so surplus can be left in the PC and deferred at ~11%. It also helps with smoothing income across higher- and lower-earning years, retirement saving inside the company, and a future sale (shares of a qualifying PC can access the lifetime capital gains exemption — $1,275,000 for 2026 dispositions — though asset-test "purification" planning often applies). If you draw essentially everything you earn, the incorporation cost, the regulator's permit and annual fees, and the extra T2/AT1 filings may not be worth it yet. Reassess as income grows.

Frequently asked questions
A professional corporation (PC) is a corporation that a regulated professional — such as a doctor, dentist, lawyer, accountant or engineer — uses to carry on their professional practice. It is incorporated under Alberta's Business Corporations Act but must also be approved and given a permit by the professional's regulatory body. A PC is taxed like any other Alberta corporation but does not shield the professional from liability for their own professional negligence.
Only members of a regulated profession whose governing legislation permits it can form a professional corporation in Alberta — including physicians, dentists, lawyers, chartered professional accountants, engineers, optometrists, chiropractors, psychologists and veterinarians, among others. You must hold a valid licence in good standing and obtain a permit from your regulatory college before the corporation can practise.
A professional corporation is taxed like any other Alberta corporation. Active professional income up to the $500,000 small-business limit is taxed at roughly 11% combined (9% federal plus 2% Alberta) and income above that at about 23% in the 2026 tax year. The professional then pays personal tax on salary or dividends withdrawn from the PC, so the main benefit is tax deferral, not a permanent rate cut.
No. A professional corporation does not protect a professional from personal liability for their own professional negligence or malpractice — that exposure remains and is covered by professional liability insurance. A PC can offer limited liability against ordinary commercial debts and contracts, but the regulator holds the professional personally accountable for the standard of their professional work.
It depends on the profession. Some Alberta regulators require that all voting shares be held by licensed members of the profession, while others permit family members to hold non-voting shares for income-splitting. The rules are set by each regulatory body, not by general corporate law, so you must check your college's specific share-ownership requirements before relying on family ownership for tax planning.
It often is once professional income reliably exceeds what you need to live on, because you can leave surplus in the PC and defer personal tax at Alberta's ~11% small-business rate. Below that, the cost of incorporating, the regulator's permit and annual fees, and a separate T2 and AT1 return can outweigh the benefit. It also helps with income-smoothing, retirement savings inside the company, and a future sale.
