Choosing Your Physician Practice Business Structure
Foundation for your medical practice
Structuring Your Medical Practice
Your business structure affects taxes, liability, succession planning, and operational flexibility. The right choice depends on your income level, risk tolerance, partnership plans, and long-term goals. According to the Canadian Medical Association, most physicians with established practices benefit from incorporating as professional corporations.
Each provincial regulatory body, such as the College of Physicians and Surgeons of Ontario or the College of Physicians and Surgeons of British Columbia, has specific requirements for medical professional corporations that must be followed.
The timing of incorporation matters significantly. Incorporating too early wastes money on accounting and legal fees, while waiting too long means missing years of tax deferral benefits. Most advisors recommend incorporating when consistent net income exceeds $150,000-$200,000 annually.
Structure Options
Professional Corp
Tax deferral, income splitting, and corporate investment opportunities for established physicians.
Partnership
Shared ownership and responsibilities with defined profit-sharing and governance agreements.
Sole Proprietorship
Simplest structure for new practices, though limited tax planning and no liability protection.
Holdco Structure
Advanced structures with holding companies for asset protection and succession planning.
