If you own a Canadian-controlled private corporation, you choose how to pay yourself: salary, dividends, or a mix. Owners tend to fixate on which one saves tax. That’s the wrong first question, because the tax system is deliberately built so that, in rough terms, it shouldn’t matter.
The theory: integration
Canada’s tax system aims for what’s called integration. A dollar earned in your corporation and paid out to you should attract about the same total tax whether it flows out as salary or as a dividend.
Salary is deductible to the corporation, so it skips corporate tax and is taxed fully in your hands. Dividends are paid from after-tax corporate income. In BC that corporate tax is 11% on the first $500,000 of active business income, and the dividend tax credit compensates you for it when the dividend is taxed personally.
In practice, integration is imperfect. Depending on the province and the year, one route leaks slightly more than the other. Usually a percentage point or two, not the windfall social media implies. The real decision turns on four things that have nothing to do with that gap.
The four factors that actually decide it
1. RRSP and CPP. Salary creates RRSP contribution room (18% of earned income, up to the annual max) and requires CPP contributions. Dividends create neither. CPP is a real cost today, since you pay both the employer and employee portions when you own the company, but it isn’t money lit on fire. It’s an inflation-indexed pension. If you value RRSP room and CPP accrual, salary wins this factor. If you’d rather invest through the corporation and skip CPP, dividends win.
2. Income smoothing and the small business deduction. Salary reduces corporate income dollar for dollar. If your corporation is bumping against the $500,000 small business deduction limit, where the combined BC rate jumps from 11% to 27%, bonusing down can keep active income in the low-rate band. Dividends don’t do this.
3. Cash flow and payroll mechanics. Salary means payroll remittances, T4s, and CPP administration on a schedule. Dividends are simpler: declare, pay, file a T5. Owners who hate administration drift toward dividends. Owners with employees already running payroll barely notice the difference.
4. What lenders and programs want to see. Mortgage qualification, parental leave benefits, and disability insurance coverage mostly look for T4 income. Two years of dividend-only compensation can complicate a mortgage application at exactly the wrong time. If a home purchase or financing event is in your two-year window, that alone can justify salary.
The honest default
For most owner-managers the answer is a mix. Enough salary to get the CPP and RRSP benefits you actually want and to satisfy any lender in your future, dividends for the rest, and a bonus-down decision at year-end if you’re near the small business deduction limit. The right mix shifts with your age, your province, your spending, and whether the corporation retains earnings to invest.
