Ontario Dentist — Compensation and Payroll Tax Planning
The Client
An Ontario dentist practising through a dentistry professional corporation needed a comprehensive review of how corporate income, personal compensation and payroll costs work together.
The Tax Issues
The dentist had followed the same compensation strategy for years without ever comparing salary and dividends in detail. That raised several important questions: was salary or dividends more tax efficient? How would each option affect personal and corporate taxes? Were unnecessary Employment Insurance premiums being paid? Could additional salary trigger Ontario Employer Health Tax?
The Solution
We completed a detailed salary versus dividend analysis built on the dentist's corporate income, personal cash requirements and long term financial objectives. The analysis weighed Ontario personal income tax, corporate income tax, CPP contributions and future benefits, RRSP contribution room, Ontario Employer Health Tax, Employment Insurance, corporate investments, personal cash flow requirements, and retirement and succession objectives.
We also reviewed the dentist's voting control of the professional corporation. An employee who controls more than 40% of a corporation's voting shares is generally not in insurable employment, meaning the dentist may have been paying EI premiums that were never required. We identified the correct treatment and explained how previously paid premiums could be corrected.
Ontario Employer Health Tax was priced into the recommendation before any change in salary, so a strategy built to reduce income tax would not quietly increase provincial payroll taxes.
The Result
The dentist walked away with a deliberate, fully coordinated compensation strategy — not a default salary-or-dividends recommendation.
The review helped:
- Eliminate unnecessary payroll costs
- Correct the treatment of Employment Insurance
- Account for Ontario Employer Health Tax
- Coordinate corporate and personal tax planning
- Put retained corporate funds to better use
- Align compensation with retirement objectives
