How Canadian corporate tax is calculated

A Canadian-controlled private corporation pays two layers of tax on active business income: federal and provincial. The federal small business rate is 9% on the first $500,000 of active business income; above that the federal general rate of 15% applies. Each province then adds its own rate on top.

Salary or dividends: which is better?

There is no universal answer, which is why the calculator above compares them on your actual numbers. Salary is deductible to the corporation, creates RRSP contribution room, and builds CPP entitlement, but it attracts CPP on both the employee and employer side. Dividends avoid CPP entirely and are taxed at lower personal rates because of the dividend tax credit, but they are paid out of income the corporation has already been taxed on, and they create no RRSP room.

Canada's tax system is built around integration, the principle that income earned through a corporation and paid out should face roughly the same total tax as income earned directly, so the two routes usually land close together. The gap that remains is what makes the decision worth running.
