For many Canadian dentists, incorporating a professional corporation is one of the most powerful financial moves available - but only once your income and savings rate justify it. This guide explains when it makes sense and how to use it well.
Quick answer: incorporation generally makes sense for dentists who earn more than they spend, because it allows income to be taxed at the much lower small-business corporate rate and left inside the corporation to grow. If you spend everything you earn, the benefit is smaller.
The core benefit: tax deferral
Inside a professional corporation, active business income up to the small-business limit is taxed at a far lower rate than top personal rates. The dentist only pays personal tax when money is withdrawn as salary or dividends. Money left in the corporation can be invested and compounded, creating a powerful deferral.
When incorporation makes sense for a dentist
| Situation | Incorporate? |
|---|---|
| You earn more than you need to live on | Strong yes - defer tax and invest the surplus |
| You are paying down student debt aggressively | Often yes - model the trade-off |
| You spend essentially all of your income | Weaker case - less to retain and defer |
| Associate early in career, lower income | Usually wait until income rises |
Beyond tax deferral
A professional corporation also enables:
- Income splitting with family members where permitted under current rules
- Corporate-owned life insurance as a tax-efficient way to move wealth out of the corporation
- A structured plan for retained earnings and eventual retirement
- A vehicle that supports practice purchase and succession planning
The retained earnings question
The real planning challenge is not whether to incorporate, but what to do with the money you keep inside the corporation. Passive investment income inside a corporation is taxed differently and can affect your small-business limit, so the investment strategy must be deliberate. This is where coordinated tax and investment planning pays for itself.
