As a physician, you make critical decisions daily. Your financial choices should be handled with the same level of expertise. For doctors in Ontario, establishing a Professional Corporation is a key step towards tax efficiency and long-term wealth preservation.

A properly structured and well-maintained professional corporation gives physicians meaningful control over income, taxation, and long-term wealth. Offering accounting services for doctors, we translate that potential into tangible outcomes through strategies built around how you actually earn and spend money.
Medical income is rarely simple. Billing through the OMA, receiving hospital privileges income, and managing overhead costs all interact in ways that require deliberate tax planning rather than reactive filing. As your accountant for doctors, we build strategies around your specific income pattern.
When we structure your plan, we considert:

Retaining income inside the corporation exposes it to the lower corporate tax rate, preserving capital for reinvestment or future distribution. As a CPA for doctors, we show you how to use retained earnings strategically.

A specialist accountant for doctor clients understands the CPSO's requirements for professional corporations, the nuances of OMA billing income, the interaction between corporate and personal tax for physicians, and the retirement and succession planning considerations unique to medical professionals.
Most physicians benefit once their net billings consistently exceed what they need for personal living expenses. The tax savings from retaining income at the corporate rate rather than withdrawing it personally can be significant.
The optimal mix of salary and dividends changes each year based on your practice income, personal expenses, RRSP contribution room, and planned investments. We review and adjust your compensation structure annually so your overall tax position is always optimized — not set once and forgotten.
Yes. Incorporating does not eliminate access to registered accounts, but it does change how you approach them. We help physicians integrate corporate and personal planning so your RRSP contributions, TFSA deposits, and any individual pension plan contributions work together as a coordinated retirement strategy.
With proper planning and organized documentation, most physicians can complete the incorporation process within a few weeks. We manage the accounting components, guide you through the CPSO approval process, and set up your corporate systems so you are operational as quickly as possible.

Your professional corporation is one of the most significant financial decisions of your medical career. Getting the structure right from the beginning — and maintaining it properly over time — is what separates physicians who build lasting wealth from those who leave significant tax savings behind.
