Accountant for Medical Professionals in Ontario
Remote CPA accounting and tax for doctors, dentists and healthcare professionals in Ontario — including Ancaster, Dundas and the Hamilton area.
An Ontario physician or dentist may incorporate under the health regulatory college's rules, which govern who may hold shares. The tax benefit is deferral on earnings retained in the corporation — and most medical services are exempt from HST rather than zero-rated.

Exempt is not the same as zero-rated, and it costs you
Most services provided by a physician or dentist to a patient are exempt supplies for HST purposes. Exempt means no tax is charged — and, critically, no input tax credits can be claimed on the costs of providing them. That is the opposite of zero-rated, where no tax is charged but credits remain fully recoverable. A practice that assumes it is zero-rated will claim credits it is not entitled to, and the correction arrives with interest. Where a practice also has taxable revenue — cosmetic procedures, certain third-party reports, teaching or consulting income — it may be required to register and can then recover credits on the taxable portion only, which requires a defensible apportionment method rather than a round-number split.
Incorporating is worth it only on what stays in
The benefit of a medicine professional corporation is deferral: income taxed at the small business rate and left inside compounds on a larger after-tax base, with the balance paid on withdrawal. A physician who draws everything each year captures very little of that while carrying the cost of a corporate return, financial statements and a payroll account. Where earnings genuinely exceed personal needs, the accumulation is substantial — and eventually generates enough passive investment income to grind down the small business limit, which is usually when a holding company enters the conversation. Who may hold shares is decided first by the college's rules and only then by the tax on split income rules. Getting that order wrong produces a structure that has to be unwound, and unwinding can itself be taxable.
