A physician, dentist, lawyer, accountant, consultant or other professional corporation can pay the owner salary, dividends, a combination of both, or retain earnings in the company. Each choice affects personal taxable income differently. Some lenders rely primarily on personal income; others may consider corporate net income, ownership share, add-backs or broader business-for-self programs when the documentation supports it.
The analysis must avoid double counting. Salary and dividends paid to the shareholder are already expenses or distributions reflected in the corporation's statements. Adding corporate income without understanding the accounting can overstate capacity. Conversely, relying only on T1 income can understate sustainable cash flow where substantial earnings remain in the business.
Professional corporations also differ from ordinary small businesses because revenue may be tied closely to the practitioner's licensed work, billing model and practice continuity. That can strengthen predictability, but lender policy still governs what can be used.
