Professional corporations in British Columbia: where the surplus goes

A professional corporation is an ordinary British Columbia company with two differences. Its shareholders are restricted by the professional's regulator, and the Income Tax Act singles it out by name in the rules that govern income splitting. The first difference decides what structures are possible. The second decides what the surplus inside the corporation can and cannot do. Together they explain why a specialist with $300,000 a year of retained earnings so often ends up asking about life insurance.

Who can incorporate, and who may hold the shares

Health professions incorporate under the Health Professions and Occupations Act, which replaced the Health Professions Act on 1 April 2026, with a permit from the relevant college. Lawyers incorporate under the Legal Profession Act with a Law Society permit, accountants under the Chartered Professional Accountants Act, and engineers and architects under their own statutes. Each regulator sets its own shareholding rule, and the rule matters more than the statute.

The physician's rule is the tightest and shapes everything that follows: the doctor must personally hold every voting share, and a holding company may hold only non-voting shares. The College's bylaws under the new Act, finalised for 1 April 2026, carried that restriction forward unchanged. The accountant's rule is the loosest, and an accounting practice can sit under a holding company like any other business.

The surplus problem

Active income inside a professional corporation is taxed at 11 percent on the first $500,000 in British Columbia. The same income taken personally at the top bracket is taxed at 53.5 percent. The gap, 42.5 points, is not a saving but a deferral; the second layer of tax arrives when the money is paid out as a dividend. It is, however, a deferral the professional controls, and it is why a surgeon who draws $200,000 and bills $500,000 net accumulates something like $250,000 of after-tax surplus a year. Over a decade that is two to three million dollars with nowhere obvious to go.

Three rules narrow the options.

Income splitting is largely closed

The tax on split income applies to dividends paid to a professional's spouse or adult children unless an exception applies. The exception most private businesses use, the "excluded shares" test, is unavailable by definition: the Income Tax Act excludes corporations carrying on the practice of an accountant, dentist, lawyer, medical doctor, veterinarian or chiropractor. What remains is the excluded business exception for a family member who works in the practice on a regular, continuous and substantial basis, generally read as twenty hours a week or more, and the rule that once the professional is 65 dividends to a spouse are treated as the professional's own. For most families that means dividends to a spouse are taxed at the top rate during the working years.

Passive income erodes the small business rate

Once a corporation and its associated companies earn more than $50,000 of adjusted aggregate investment income in a year, the $500,000 small business limit falls by five dollars for every dollar above the threshold, and is gone at $150,000. Two million dollars of surplus in bonds at 4 percent produces $80,000 of investment income and strips $150,000 from the limit, so that slice of practice income is taxed at the general rate of 27 percent instead of 11. The cost is about $24,000 a year, and it rises with the portfolio.

Registered room does not scale

An RRSP takes at most about $32,000 a year and a TFSA $7,000. An individual pension plan helps a professional over 50 with a salary history, and belongs in the plan, but it too has a ceiling. None of these absorb a surplus measured in hundreds of thousands a year.

Why the surplus ends up in a participating policy

Set the three rules beside the features of an exempt participating whole life policy owned by the corporation and the fit is close.

• The growth is not investment income. Cash value accumulating inside an exempt policy is not adjusted aggregate investment income. It does not count toward the $50,000 threshold and does not grind the small business limit.
• There is no contribution limit. The premium is bounded by underwriting and by what the corporation can sustain, not by a statutory cap.
• The exit is not split income. On death the proceeds above the policy's adjusted cost basis are credited to the capital dividend account and paid to shareholders tax-free. A capital dividend is not a taxable dividend, and the tax on split income does not reach it. For a professional whose spouse and children hold non-voting shares, this is the one route by which corporate surplus reaches the family without the second layer of tax.
• The capital is not locked up. A lender will advance against the cash value without triggering a disposition, which is the basis of leveraged corporate life insurance.

None of this makes the policy an investment. The premium is a cost, the death benefit is the product, and the cash value is a by-product of funding permanent coverage ahead of the mortality curve. The point is that for a professional corporation the by-product is taxed more gently, and the exit is cleaner, than any portfolio the corporation could hold instead.

Structure by profession

Accountants, lawyers and others who may use a holding company

Where the regulator allows a holding company to own the professional corporation's voting shares, the standard structure applies. The practice pays dividends to the holding company, which receives them tax-free as a connected corporation. The holding company owns the policy, holds the investments and carries no operating risk, so the policy sits behind the practice's creditors. An estate freeze can later move the growth to a family trust holding the holding company's shares. This is the cleanest version and it is available to most accountants, and to lawyers within the Law Society's rules.

Physicians and dentists

Because a physician's holding company can hold only non-voting shares of the medical corporation, the companies are generally not "connected" for tax purposes, and dividends from the practice to the holding company attract a refundable tax of 38⅓ percent on the way through. That removes the easy route. Three workable alternatives remain.

1. The medical corporation owns the policy directly. Simplest, and the usual answer for a solo practitioner with modest litigation exposure. The trade-off is that the policy is an asset of the practice company and sits with its creditors.
2. A management fee to the holding company. The practice pays the holding company a fee at fair market value for documented services; the fee is deductible to the practice and income to the holding company, which funds the policy from it. This avoids the connected-corporation problem and gives the holding company a real purpose, but the fee has to be defensible.
3. A share class with limited voting rights. Some practitioners design a share class for the holding company that votes only on narrow matters, enough to meet the tax test without offending the College's rule. It is aggressive, it depends on how the College reads "voting share", and it needs a written legal opinion before anyone relies on it.

In practice, most physician cases we see use the first or the second. The third is raised only when the amounts justify the legal cost and the lawyer is prepared to put the opinion in writing.

Ontario in one paragraph

Ontario professional corporations are formed under the Business Corporations Act with a certificate of authorization from the regulator. The Ontario rule for physicians and dentists is more permissive on the family side, allowing a spouse, children and parents to hold non-voting shares directly, but the voting shares must still be held by the professional and the same federal rules on split income and passive income apply. The structural analysis above carries across with the provincial small business rate at 12.2 percent and the probate figure at 1.5 percent.

Where to start

Four documents settle the design: the corporation's financial statements, which show the surplus, the passive income and whether the limit is already being ground down; the central securities register, which shows who holds what class of share and whether a holding company exists; the most recent personal tax return, which shows the salary and dividend mix; and the regulator's current shareholding bylaw. Metacap Financial works through these with the professional's accountant before any illustration is run, because the ownership question has to be answered first and the answer is different for a dentist than for a CPA. The question for the insurance is then the ordinary one: how much permanent coverage the estate needs, and how much of the surplus should fund it ahead of time.
