Should I Incorporate My Medical Practice in BC? A Plain-Language Guide for Physicians and Dentists
The short answer: incorporation makes sense for most BC physicians and dentists once you're consistently earning more than you spend — because the biggest benefit is tax deferral on income you leave inside the corporation. If you're spending everything you earn, incorporation adds cost and complexity without much payoff. Here's how to think it through properly.
What a professional corporation actually is
In BC, physicians and dentists don't practise through a regular company — they use a health professions corporation, approved by their regulatory college. The corporation bills for your services, pays its expenses, and pays you by salary or dividends. You still carry personal professional responsibility; incorporation doesn't shield you from malpractice claims. What it changes is how and when your income is taxed.
The core benefit: tax deferral
A BC corporation earning active income generally pays roughly 11% combined tax on its first $500,000 of active business income (the small business rate), versus personal marginal rates that can exceed 50% at high incomes.
That gap is the whole game. Say your practice earns $400,000 and you need $220,000 to live on. Unincorporated, the full $400,000 is taxed personally in the year you earn it. Incorporated, you pay yourself the $220,000 and leave the rest in the corporation, where it's initially taxed at roughly 11%. The difference — often tens of thousands of dollars per year — stays invested and compounding inside your corporation until you need it, typically in lower-income years or retirement.
Two important caveats:
It's a deferral, not a permanent saving. When you eventually pull money out as dividends, personal tax applies. The system is designed so that, over a lifetime, incorporated and unincorporated income end up taxed roughly the same. The win comes from decades of investing pre-tax dollars — and from smoothing income into lower-tax years.
Income splitting is mostly gone. Since the TOSI (tax on split income) rules took effect, paying dividends to a spouse or adult children who don't genuinely work in the practice usually triggers top-rate tax. There are exceptions (for example, a spouse who works meaningful hours in the practice, or once you're 65+), but the "sprinkle dividends to the family" strategy of the 2000s is largely closed. Anyone still pitching it to you as a headline benefit is out of date.
Other real benefits
Individual Pension Plans and corporate retirement strategies become available at higher incomes.
The Lifetime Capital Gains Exemption may apply if you eventually sell shares of a qualifying practice (more realistic for dentists selling a practice than for physicians).
Flexibility in timing income — parental leave, sabbaticals, and part-time years become far more tax-efficient when you can dial your draws up or down.
Paying certain expenses corporately, including a health spending account for your family's medical costs.
The honest costs
Setup: legal and college-permit costs, typically a few thousand dollars.
Ongoing: corporate year-end financial statements and a T2 return, a separate GST account if applicable, payroll if you take salary, and annual college renewal. Budget several thousand per year in professional fees.
Complexity: a corporate bank account, clean bookkeeping, and discipline about not treating the corporate account as a personal wallet (shareholder loan problems are one of the most common CRA issues we see).
The break-even test
Ask one question: will I reliably leave at least $50,000–$100,000 per year inside the corporation? If yes, the deferral usually outruns the costs comfortably. If you're a resident, a new associate with student debt, or you're spending most of what you earn while building a life, it's often better to wait a year or two — incorporation is easy to add later, and there's no prize for doing it early.
Watch the passive income rules
Money left in the corporation gets invested, and investment income inside a corporation is taxed at high rates. Once your corporation's passive investment income exceeds $50,000 per year, your access to the low small-business tax rate starts shrinking. This is manageable with planning (corporate-owned insurance structures, IPPs, asset allocation choices) — but it's a reason incorporated professionals benefit from an accountant who plans ahead rather than just filing what happened.
A Surrey-specific note
If you're finishing residency at Surrey Memorial or joining a practice in the Lower Mainland, the decision usually lands like this: locum or associate year one — hold off; established billings and a gap between earnings and spending — incorporate, and set up your remuneration plan before your first corporate year-end, not after.
The bottom line
Incorporation is a powerful tool for BC physicians and dentists — but it's a cash-flow and lifestyle decision as much as a tax one. The right answer depends on your billings, spending, debt, and family situation.

FAQ
How much does it cost to incorporate a medical practice in BC? Typically a few thousand dollars in legal and college fees to set up, plus annual accounting and renewal costs. The deferral benefit usually needs to exceed roughly $5,000–$8,000/year in ongoing costs to be worthwhile.
Can I pay my spouse dividends from my medical corporation? Usually not without triggering TOSI top-rate tax, unless your spouse genuinely works in the practice or another exception applies. Get specific advice before doing this.
Should I incorporate during residency? Almost never. Residents rarely have surplus income to leave in a corporation, which is where the benefit comes from.
Does incorporation protect me from being sued? No — professional liability follows you personally. Incorporation is a tax and financial-planning tool, not liability protection.
