Incorporation isn’t available to every professional in BC, it’s governed by a patchwork of professional regulatory bodies, each with their own rules about who can hold shares, what the corporation can do, and what protections it does and doesn’t provide. Doctors, dentists, lawyers, engineers, accountants, and several other professions can all incorporate in BC, but the structures and restrictions aren’t identical across them.
If you’re a regulated professional in BC who hasn’t incorporated yet, or if you incorporated years ago without a clear understanding of what your structure actually enables, this is worth revisiting. The tax deferral and retirement planning advantages of a professional corporation remain significant; but they work differently than many professionals assume.
What a professional corporation (PC) is in BC
A professional corporation is a specific type of corporation authorized under BC’s Business Corporations Act combined with the regulatory requirements of a profession’s governing body. It allows regulated professionals, physicians, dentists, lawyers, engineers, accountants, veterinarians, and others, to carry on their professional practice through a corporation rather than personally or through a partnership.
The key legal distinction: the professional corporation provides tax advantages but does not limit professional liability. A physician operating through a PC is still personally liable for their professional acts and omissions. The corporation cannot shield you from malpractice claims. This is different from a typical business corporation where shareholders are generally protected from the company’s debts and liabilities.
What the PC does protect against is personal liability for non-professional obligations, business debts, lease agreements, staff-related disputes, to the same extent as any other corporation. That’s still meaningful, particularly for practice owners with significant overhead.
Who can own shares in a BC professional corporation
This is where the rules get profession-specific, and getting it wrong has real consequences.
For most regulated professions in BC, shares must be held only by members of the profession in good standing. In some professions, a spouse can hold shares. In others, no non-member can hold shares at all. Lawyers in BC, for example, must be the sole shareholder of their law corporation under the Law Society of BC’s rules. Physicians can have a spouse hold shares in some circumstances.
The TOSI rules layer on top of the professional restrictions. Even where a spouse is legally permitted to hold shares, dividends paid to them must meet the TOSI reasonable return test to avoid being taxed at the top marginal rate. In many cases, a spouse who holds shares but isn’t actively involved in the practice will receive little income-splitting benefit post-2018.
Before structuring share ownership in your PC, confirm what your specific regulatory body permits; and then run the TOSI analysis on top of that to determine what’s actually tax-beneficial given your family situation.
The core tax advantages
Small business deduction. Net income earned inside a Canadian-controlled professional corporation (CCPC) qualifies for the small business rate, approximately 11% combined federal and provincial in BC on the first $500,000 of active business income. A physician earning $500,000 in professional fees and paying themselves $200,000 in salary retains $300,000 in after-tax corporate earnings at roughly 11% corporate tax, rather than paying personal tax at up to 53.5%. Over a 20-year career, that deferral compounds dramatically.
RRSP room from salary. The salary you pay yourself from the PC creates RRSP contribution room at 18% of earned income, up to the annual maximum. This is one reason most incorporated professionals pay themselves at least enough salary to maximize RRSP contributions, even if dividends are more tax-efficient on the marginal dollar.
Retirement income flexibility. The accumulated retained earnings inside the PC can be drawn down in retirement, ideally in years when your income is lower than your peak earning years, through dividends. The combination of corporate tax deferral and personal tax rate arbitrage between high-earning years and retirement years is the financial engine that makes incorporation powerful over a career.
Corporate-owned life and disability insurance. The PC can own key-person insurance, disability overhead expense insurance, and corporate-owned life insurance. Premiums paid by the corporation may be deductible in some circumstances, and life insurance proceeds flow through the Capital Dividend Account, enabling tax-free distributions to beneficiaries or surviving shareholders.
The professional corporation and the holdco question
Many regulated professionals ask whether they should add a holding company above their PC. The analysis is the same as for any incorporated professional: does the PC consistently generate retained earnings beyond personal needs, and is there value in the creditor protection, investment deferral, and estate planning flexibility a holdco provides?
For professions where the regulatory body restricts PC share ownership to licensed members, adding a holdco is typically straightforward, the professional owns the holdco, and the holdco owns the PC. For professions with more restrictive rules, the structure needs regulatory sign-off before implementation.
One practical consideration unique to professional corporations: if you’re carrying significant professional liability risk, sweeping retained earnings from the PC to a holdco regularly is arguably more important than in a typical business. The PC’s exposure to professional claims means assets left there are more vulnerable than assets in a separate holding entity.
What changes at incorporation and what doesn’t
Incorporation doesn’t change your professional obligations, your regulatory requirements, or your professional liability. Your regulatory body still governs your conduct, your licencing, and your duties to clients. The corporation is simply a tax and financial planning vehicle, it doesn’t affect what you can or can’t do professionally.
What does change: your compensation structure, your RRSP room, your insurance strategy, your retirement planning options, and the way your estate interacts with your accumulated professional income. These are significant changes that, over a career, represent hundreds of thousands of dollars in decisions made well or poorly.
Frequently Asked Questions
Who can incorporate as a professional corporation in BC?
Most regulated professions in BC can incorporate, including physicians, dentists, lawyers, engineers, accountants (CPA), veterinarians, architects, and others. Each profession has specific requirements under its governing body’s rules about who can hold shares, what the corporation can do, and what name it can use. Confirm with your regulatory body before structuring.
Does a professional corporation limit my liability for malpractice?
No. A professional corporation does not limit personal liability for professional negligence or malpractice. You remain personally liable for your professional acts and omissions regardless of whether they are performed through a corporation. The PC does limit liability for non-professional business obligations (debts, leases, employee disputes) to the same extent as any other corporation.
Can my spouse own shares in my professional corporation in BC?
It depends on your profession’s regulatory rules. Lawyers in BC generally cannot have any non-member shareholders. Physicians may be able to have a spouse hold shares in some circumstances. Even where the regulatory body permits it, the 2018 TOSI rules mean dividends to a non-active spouse are taxed at the top marginal rate, significantly limiting the income-splitting benefit. Always confirm both the regulatory and the tax analysis before structuring share ownership.
When does it make financial sense to incorporate as a professional in BC?
The financial case for incorporation strengthens as your net professional income exceeds your personal living expenses, roughly when you’re earning $150,000 or more and not consuming everything you earn. The combination of the small business rate deferral, RRSP room from salary, and retirement income flexibility creates compounding benefits over a multi-decade career. Earlier incorporation generally captures more of those benefits.
