Assumptions behind these numbers ▾
Both routes start from the same pre-tax corporate profit. On the salary route, the profit pays the gross salary plus every employer-side payroll cost, and because salary is deductible there is no corporate tax on it. On the dividend route, the corporation pays tax on the profit first, then pays out what is left as a dividend. Small business rate income is paid as a non-eligible dividend; general rate income as an eligible dividend. Active business income earns no RDTOH refund.
Corporate rates for a calendar-year corporation in 2026: 9% federal plus 3.2% in Quebec (12.2% combined) or 2.7% in Ontario (11.7% combined, a blend of 3.2% before July 1 and 2.2% after) under the small business deduction, or 26.5% combined at the general rate. In 2027 the small business rate is 2.2% in both provinces (11.2% combined). In Quebec, the provincial small business rate needs at least 5,500 paid hours in the year (including associated corporations); it shrinks in a straight line between 5,500 and 5,000 hours, and at 5,000 hours or fewer the Quebec rate is 11.5% (20.5% combined).
The 2027 option applies the announced small business rates and the lower provincial credits on non-eligible dividends received from January 1, 2027 (Quebec 2.69% instead of 3.42%, Ontario 1.99% instead of 2.99%, as a share of the grossed-up dividend). Personal brackets and payroll amounts for 2027 are not published yet, so 2026 values are used.
Personal tax uses 2026 federal, Quebec and Ontario brackets, basic personal amounts, credits for CPP or QPP, EI and QPIP, the deduction for enhanced contributions, the Canada employment amount, the Quebec abatement and deduction for workers, the Ontario surtax and health premium, and dividend gross-up and tax credits. It is measured as the extra tax from adding this income on top of your other income.
Payroll uses 2026 CPP, QPP, EI and QPIP rates and maximums. Quebec salary also carries the Health Services Fund at the small-employer rate (1.65%, total payroll up to $1M) and the labour standards contribution. Ontario's Employer Health Tax is not charged because payroll under $1M is exempt. Workers' compensation is not included.
