Tax and accounting for healthcare professionals in Canada
Healthcare professionals in Canada have access to significant tax planning opportunities — professional corporations, the small business deduction, income splitting — but also face unique complexity around HST exemptions, provincial billing systems, and how to structure arrangements with locums and associates. This guide covers the key issues for physicians, dentists, optometrists, pharmacists, physiotherapists, chiropractors, registered nurses, and nurse practitioners.
Professional corporations for healthcare professionals
Most Canadian provinces allow regulated health professionals to incorporate a professional corporation (PC). Unlike regular corporations, PCs must comply with the applicable regulated profession's rules — the corporation must be owned and controlled by licensed professionals in the same field, and the professional remains personally liable for professional negligence regardless of the corporate structure.
Which professionals can incorporate
Provincial rules vary. In Ontario, the following professions can incorporate under the Regulated Health Professions Act and its regulations: physicians, dentists, veterinarians, optometrists, pharmacists, physiotherapists, chiropractors, registered nurses, and several others. In BC, Alberta, and most other provinces, similar lists exist. Check with your regulatory college — some professions gained incorporation rights only recently, and the rules for share ownership vary.
Why incorporation makes sense
The primary benefit is tax deferral. Income earned inside the corporation is taxed at the small business rate (approximately 11–14% combined federal-provincial on the first $500,000) rather than at your personal marginal rate (45–53% at high incomes). Money left inside the corporation can be invested and compound at the lower corporate tax rate, with the personal tax payable only when you eventually pay yourself a dividend or salary.
Secondary benefits include estate planning flexibility (family members may be shareholders in some structures), potential income splitting (subject to TOSI rules), and the ability to manage the timing and amount of personal income each year.
Costs and considerations
Incorporation is not free — expect $2,000–$5,000 for initial setup (corporate registry, share structure, shareholder agreement, professional college approval) and $1,500–$3,000 annually for corporate tax preparation and additional compliance. For a professional earning $400,000 annually and leaving $150,000 inside the corporation, the annual tax savings typically dwarf these costs many times over.
The small business deduction
A Canadian-controlled private corporation (CCPC) — which a professional corporation is, as long as it is majority-owned by Canadian residents who are not public corporations — can claim the small business deduction on active business income up to $500,000 per year. This reduces the federal corporate tax rate from 15% to 9%. Combined with provincial small business rates, the effective combined rate is roughly 11% in Alberta, 12.2% in Ontario, and 11% in BC.
This compares against a top combined federal-provincial personal marginal rate of approximately 50–54% for high-income professionals. The gap — roughly 40 percentage points — is why incorporation creates such large tax deferral benefits for high earners.
The $500,000 SBD limit is shared among associated corporations. If you have a spouse or family member who also operates a PC, and CRA considers them associated, the $500,000 limit is shared. Get advice before setting up multiple corporations in the same household.
Provincial billing and fee-for-service income
In provinces with public health insurance (OHIP in Ontario, MSP in BC, AHCIP in Alberta), fee-for-service billings for insured services are the primary revenue stream for most physicians. These billings are business income — they are earned by the professional and, if incorporated, by the professional corporation.
Unpaid billings at year-end
Under accrual accounting (required for corporations), billings that have been submitted to the provincial health plan but not yet paid at year-end are accounts receivable. This is particularly relevant for year-end planning — a large batch of unpaid billings outstanding at December 31 is income earned in that year even if payment arrives in January.
Reciprocal billing and out-of-province services
Physicians who see patients from other provinces — common in border cities or tourist areas — bill the home province's plan under reciprocal billing agreements. These payments are also business income. The administrative process differs from direct provincial billing, but the income tax treatment is the same.
HST exemptions for medical services
Many healthcare services are exempt from GST/HST under Schedule V, Part II of the Excise Tax Act, but the exemption is more specific than many professionals assume.
Generally exempt services
- Physicians' services rendered to an individual (all services rendered by a practitioner of the profession of medicine)
- Dentistry for therapeutic purposes (not cosmetic)
- Optometry services
- Pharmacy dispensing fees
- Nursing services
- Physiotherapy in provinces with a provincial exemption (Ontario, NB, PEI, NS)
- Chiropractic in provinces with a provincial exemption
Generally taxable services
- Cosmetic procedures: any service that is primarily for cosmetic purposes and not medically necessary is taxable regardless of who performs it
- Physiotherapy in provinces without a provincial exemption
- Massage therapy (generally taxable across Canada)
- Naturopathic services
- Psychological services (though counselling for mental health is exempt in some provinces)
If your practice offers a mix of exempt and taxable services, you need to track them separately. Input tax credits are available only for inputs used in taxable activities. This requires an allocation between taxable and exempt activities, which your accountant can help you set up.
Overhead expenses and capital cost allowance
Deductible business expenses for a healthcare practice are similar to any professional services business, with some specific items:
- Office rent: Fully deductible if used for practice purposes.
- Staff wages and benefits: Reception, nursing staff, dental hygienists — fully deductible, with T4s and CPP/EI required.
- Medical and dental supplies: Gloves, syringes, materials — fully deductible in year purchased.
- Medical equipment (CCA Class 10): Examination tables, X-ray equipment, dental chairs — 30% declining balance. The accelerated investment incentive allows 1.5x the normal first-year rate for new equipment.
- Computer equipment (Class 50): 55% declining balance. EMR/EHR software may qualify for the full cost deduction in year one.
- Licensing and regulatory fees: Annual college fees, CME registration — fully deductible.
- Malpractice insurance (CMPA, etc.): Fully deductible.
Home office
A portion of home expenses is deductible if you do administrative work at home (reviewing charts, completing billing, education). The claim must be reasonable and documented — a dedicated home office space at a justifiable percentage of total home area. CRA scrutinizes large home office claims from professionals who also maintain a clinical office.
Locum and associate arrangements
Employee or contractor?
Whether a locum or associate is an employee or independent contractor is one of the most litigated questions in healthcare taxation. CRA applies the four-factor test from Wiebe Door and 671122 Ontario Ltd. v. Sagaz:
- Control: Do you tell the locum when to work, how to see patients, what billing codes to use? More control = employee.
- Tools: Do you provide the exam room, equipment, and supplies? Employer-provided tools = employee.
- Chance of profit / risk of loss: Can the locum profit more by working more efficiently, or lose money? Pure fee-for-service billing in someone else's office with no overhead risk = employee.
- Integration: Is the locum's work integrated into your practice (seeing your patients, using your billing number), or do they run their own parallel practice?
A physician coverage locum who works three days in your clinic, uses your equipment, sees your patients, and bills under your billing number looks a lot like an employee to CRA. A specialist who maintains their own independent practice and occasionally provides coverage as one of several clients looks more like a contractor. The specific facts matter enormously — get a formal analysis from a CPA before treating locums as contractors.
Associate agreements
Dental and optometry practices commonly use associate agreements where an associate professional generates revenue from patients, and pays the clinic a facility fee (for rent, staff, supplies). The associate bills the patient and keeps the fee minus overhead. This structure is generally treated as a genuine independent contractor arrangement if the associate maintains meaningful independence, but the same CRA scrutiny applies.
Income splitting strategies
Income splitting in professional corporations became much more restricted with the 2018 Tax on Split Income (TOSI) rules. Before paying dividends to a spouse or adult child, confirm with your CPA which exceptions apply.
Salary to a spouse who works in the practice
Paying your spouse a reasonable salary for work they actually perform (billing, bookkeeping, reception, management) remains a valid income splitting strategy and is not subject to TOSI. The salary must be reasonable for the work — what you would pay a non-related person for the same work. Keep documentation of the actual work performed.
Spousal loans at the prescribed rate
An alternative to dividends is lending money from the corporation to a spouse (or to you personally to lend to the spouse) at CRA's prescribed interest rate for the spouse to invest in their own name. The investment income is taxed at the spouse's lower rate. The prescribed rate must be set in the loan agreement and interest must actually be paid by January 30 of the following year. This strategy has become more attractive as prescribed rates have moderated.
Retirement planning
Unlike employees who have pension plans, incorporated professionals must self-fund retirement. Capital inside the corporation can be invested in a holding company structure, or extracted via dividends timed to lower-income years (after practice winds down). RRSP room is based on earned income in the previous year — T4 salary from the PC generates RRSP room; dividends do not.
Frequently asked questions
Should I incorporate my medical practice?
Incorporation makes sense for most healthcare professionals once their income exceeds what they need for personal expenses — typically when they are consistently earning $200,000 or more and living on less. The benefit is tax deferral: profits left inside the corporation are taxed at 9% (small business rate) rather than at your marginal personal rate of 45%+. Over time, that deferral compounds significantly. The setup costs ($2,000–$5,000 in professional fees) and annual compliance costs are usually worth it at that income level.
Are all medical services exempt from HST?
Most physician and dental services are HST-exempt under the Excise Tax Act. However, the exemption is narrower than many healthcare professionals assume. Cosmetic procedures that are not medically necessary are generally taxable. Physiotherapy services are exempt in some provinces (Ontario, New Brunswick, PEI, Nova Scotia have provincial exemptions) but taxable in others. Massage therapy is generally taxable. Chiropractic care in a province that does not have a provincial exemption is taxable. Know exactly which of your services are exempt and which are taxable before setting your billing.
What is the small business deduction for a medical professional corporation?
A Canadian-controlled private corporation (CCPC) can claim the small business deduction on active business income up to $500,000, reducing the federal corporate tax rate from 15% to 9%. Combined with low provincial rates, the effective combined rate on the first $500,000 of active business income is approximately 11-14% depending on the province, compared to 45-53% at the top personal marginal rate. The SBD is gradually reduced for corporations with taxable capital employed in Canada between $10 million and $50 million.
Can I split income with my spouse through my professional corporation?
The TOSI (Tax on Split Income) rules introduced in 2018 significantly restrict income splitting through professional corporations. Dividends paid to a spouse or family member are subject to tax at the highest marginal rate unless an exception applies. Key exceptions: the spouse works actively and meaningfully in the business (generally 20+ hours per week), or the taxpayer is 65 or older and the spouse is over 65. The rules are complex — get specific advice from a CPA before paying dividends to family members.
What is the locum arrangement risk?
Many physicians and dentists hire locums (temporary replacement professionals) as independent contractors. CRA applies a four-factor test to determine whether the arrangement is truly a contractor relationship: control over how work is done, ownership of tools, chance of profit and risk of loss, and integration into the business. A locum who works under your direction, uses your equipment, sees your patients in your office, and has no independent business is likely an employee. Misclassifying employees as contractors means unremitted CPP and EI plus interest and penalties.
