Tax planning for physicians, dentists, and other regulated professionals in Manitoba

Incorporation provides a meaningful tax advantage when your professional income consistently exceeds your personal spending needs. The key is that incorporation works best when you are not extracting all of your income personally. If you earn $200,000 and need $150,000 to live on, the remaining $50,000 retained inside the corporation is taxed at 9% in Manitoba rather than over 50% personally. The larger the gap between what you earn and what you need personally, the more meaningful the tax advantage becomes. The most common mistake we see is physicians and dentists incorporating but then pulling all of the corporation's cash out every year anyway, which defeats the purpose. The retained earnings can then be invested inside the corporation and drawn down strategically in lower-income years, during retirement. Whether incorporation makes sense depends on your income level, your personal spending needs, whether your profession is eligible, and your long-term financial goals.

Many regulated health professions are eligible to incorporate as a professional corporation, including veterinarians, optometrists, chiropractors, pharmacists, physiotherapists, and psychologists. Eligibility is governed by your specific regulatory college and varies by province. Some professions gained incorporation rights relatively recently, so if you were told years ago that you could not incorporate, that answer may now be out of date. If you are a healthcare professional and you are not sure whether your profession is eligible, book a consultation and we will find out together.

Manitoba's combined small business tax rate is 9% on the first $500,000 of active business income earned through a qualifying Canadian-controlled private corporation. This combines the federal small business rate with provincial tax rates, and the rate varies by province. Compared to the personal top marginal rate of over 50%, the gap is substantial. For a physician, dentist, or veterinarian who earns more than they need personally and retains the surplus inside their professional corporation, the annual tax saving on that retained amount is significant. Compounded over a 25 to 30 year career, the difference in net wealth is material.

A Medical Professional Corporation is a corporation owned by one or more licensed health professionals that earns income from the provision of professional services. Provincial legislation governs which professions are eligible and under what conditions. The MPC bills for professional services, receives income at the corporate level, pays the professional a reasonable salary or dividend, and retains the remainder inside the corporation at the small business tax rate. The professional must remain licensed and in good standing with their regulatory college for the corporation to operate.

There is no universal answer, which is why this question comes up every year. Salary creates RRSP contribution room, CPP contributions, and a deductible expense for the corporation. Dividends are taxed at a lower personal rate but create no RRSP room or CPP entitlement. The right split for a healthcare professional depends on RRSP room goals, CPP reliance in retirement, personal spending needs, spousal income, and whether other retirement vehicles like an IPP are in place. Most incorporated healthcare professionals end up with a combination of both, calibrated annually to their specific situation and provincial tax rates.

The small business deduction, which gives your professional corporation access to the small business tax rate on its first $500,000 of active income, is reduced when your associated corporations collectively earn more than $50,000 in passive investment income in the prior year. For every dollar above $50,000, you lose $5 of small business limit. At $150,000 in passive income, the deduction is eliminated entirely. For healthcare professionals who have been accumulating retained earnings and investing them inside their professional corporation, this threshold can become relevant quickly. Strategies include moving investment assets to a holding company or restructuring how income is drawn from the corporation.

A holding company makes sense once your professional corporation is consistently generating more retained earnings than you need personally. The holding company receives dividends from the professional corporation on an inter-corporate tax-free basis, keeping those funds away from professional liability exposure. Inside the holding company you can invest in a diversified portfolio, hold real estate, or lend funds back to the professional corporation if needed. It also simplifies estate planning and can help manage the passive income grind-down. For most healthcare professionals with stable incomes above their personal spending needs, a holding company pays for itself within a few years.

Most residents are not yet eligible to incorporate because a professional corporation requires a full independent license to practice, which residents do not hold during training. However, the planning conversations should start well before graduation and at the end of residency. The financial decisions made in the first year of independent practice, including whether to incorporate, how to structure compensation, and whether to set up a holding company, have consequences that compound over an entire career. We offer complimentary personal tax returns for medical residents and dental students, and we regularly speak with students and residents at the University of Manitoba so that the structure is ready to implement the day they are eligible. There is no better time to start the conversation.

Legitimate business expenses incurred to earn professional income are deductible at the corporate level for professional corporations. This typically includes professional liability insurance, regulatory college fees, continuing medical or professional education, professional memberships and dues, office or clinic expenses where you are not reimbursed, accounting and legal fees, and reasonable home office expenses. The corporation can also cover a Health Spending Account, allowing personal medical expenses to be paid through the corporation on a tax-deductible basis. Expenses that are personal in nature are not deductible regardless of whether they are paid through the corporation.

The wind-down of a professional corporation is a planning exercise that should begin well before your retirement date. Options include drawing down retained earnings gradually over several years as lower-income dividends in retirement, transferring assets to a holding company before winding down the professional corporation, using the Lifetime Capital Gains Exemption on the sale of qualifying shares, or continuing the holding company indefinitely and drawing from it on your own schedule. The right approach for a healthcare professional depends on how much is inside the corporation, personal income in retirement, estate planning goals, and whether the shares qualify for the Lifetime Capital Gains Exemption. Planning for this should begin at least five to ten years before you stop practicing.

This is one of the most common planning questions we get from physician and dentist clients. During a parental leave, no professional income flows through the corporation, but the corporation continues to exist and carries its own administrative costs including accounting fees and corporate filing requirements. The good news is that a parental leave is often one of the best times to draw dividends from your retained earnings at a lower personal tax rate, since your total income for the year is likely reduced. It can also be a valuable window to review your corporate structure and ensure everything is optimized before you return to practice. Planning ahead before your leave starts can make a meaningful difference in how efficiently you use this period.

The Tax on Split Income (TOSI) rules significantly restricted income splitting with family members for incorporated professionals. Under the current rules, dividends paid to a spouse from your professional corporation are generally subject to the highest marginal tax rate unless the spouse meets specific criteria, most commonly actively working in the business for an average of at least 20 hours per week. Once your spouse reaches age 65, income splitting becomes available regardless of their involvement in the practice. Non-voting shares for family members remain part of many corporate structures, but the tax benefit is limited for most physicians and dentists until retirement age. The right answer depends on your specific family and practice situation and is worth reviewing carefully with your accountant.
