For owners of incorporated businesses, the question of how to pay yourself — salary, dividends, or some combination of both — is one of the most common tax planning questions, and one without a single universal answer. The Canadian tax system is designed around a principle of "integration," meaning that, in theory, the total tax paid on a dollar of business income should be roughly similar whether it is paid out as salary (deducted by the corporation, taxed personally) or as dividends (not deducted by the corporation, taxed at the corporate level, then taxed again personally at a reduced rate to account for the corporate tax already paid). In practice, the choice still matters — because of factors integration does not fully capture.
The salary-versus-dividend decision is rarely about which option results in less tax on the dollar in question — integration makes these reasonably close. It is more often about the secondary effects: CPP contributions and benefits, RRSP contribution room (which is based on earned income, including salary but not dividends), and how the choice affects the corporation’s ability to access certain provisions. These secondary effects often matter more than the headline tax comparison.
Salary: The Basics
Salary paid to a shareholder-employee is a deductible expense to the corporation (reducing corporate taxable income) and is taxed as employment income to the individual, subject to the same personal tax rates and CPP contributions (both employer and employee portions, in this case, since the individual is effectively both) as any other employment income.
Dividends: The Basics
Dividends are paid from the corporation’s after-tax income — meaning the corporation has already paid corporate tax on the income before it is distributed as a dividend. The individual receiving the dividend reports it on their personal return, with a "gross-up" and corresponding dividend tax credit designed to approximate the corporate tax already paid, so the individual is not taxed on the full dividend amount without recognition of the tax the corporation already paid on that income.
The CPP Consideration
Salary generates CPP contributions and corresponding CPP benefit entitlement; dividends do not. This cuts both ways:
- Paying salary means contributing to CPP (both portions, paid personally as a self-employed-equivalent contributor in this context) — a cost in the current year, but builds CPP benefit entitlement for retirement.
- Paying dividends only avoids CPP contributions entirely — saving the contribution cost, but resulting in no CPP benefit accrual for that income, which may mean a smaller CPP retirement benefit (or none at all, if dividends are the only form of compensation throughout a working life).
Whether this matters depends on the individual’s broader retirement income plan — someone who is building substantial retirement savings within the corporation, or through other means, may view CPP as a relatively minor piece of their retirement income and be comfortable foregoing it; someone relying more heavily on government benefits in retirement may place more value on CPP accrual.
The RRSP Room Consideration
RRSP contribution room is based on "earned income," which includes salary and self-employment income, but does not include dividends. An owner who pays themselves entirely through dividends does not generate new RRSP room — meaning that if RRSP contribution room and the associated tax-deferred retirement savings is part of the plan, at least some salary is generally needed to generate that room.
This is one of the more commonly cited reasons for a "mixed" approach — paying a salary sufficient to generate meaningful RRSP room (and potentially to maximize CPP contributions, if that is a goal) while paying additional compensation as dividends.
Other Considerations
Provincial Health Premiums and Other Income-Tested Benefits
Some provincial programs and benefits are based on net income, which includes both salary and the grossed-up amount of dividends — meaning the choice can affect eligibility for certain income-tested benefits or premiums, depending on the province and the specific programs involved.
Income Splitting Implications
As discussed in our companion article on income splitting, dividends paid to family members who are shareholders are subject to the Tax on Split Income (TOSI) rules unless specific exceptions apply — while salary paid to family members is assessed against the "reasonableness" standard for the work performed. The two approaches have different rules governing income splitting with family members, which may be relevant if family income splitting is part of the broader plan.
Cash Flow and Administrative Considerations
Salary requires payroll remittances (source deductions for income tax, CPP, and if applicable EI) on a regular schedule, while dividends do not have the same withholding requirements (though they are still taxable and need to be accounted for when the individual files their personal return, potentially requiring instalment payments if the resulting tax owing is significant). Some business owners prefer the more "automatic" nature of payroll remittances; others prefer the cash flow flexibility of dividends, with personal tax addressed at filing time (or through instalments).
A Simplified Comparison
| Factor | Salary | Dividends |
|---|---|---|
| Generates RRSP room | Yes | No |
| CPP contributions and benefit accrual | Yes (cost now, benefit later) | No |
| Deductible to corporation | Yes | No (paid from after-tax corporate income) |
| Payroll remittance requirements | Yes | No |
| Income splitting with family (if applicable) | "Reasonableness" standard for work performed | Subject to TOSI rules unless exceptions apply |
| Overall personal + corporate tax (due to integration) | Broadly similar | Broadly similar |
Why a Mixed Approach Is Common
Given that the headline tax difference is often modest due to integration, but the secondary effects (RRSP room, CPP, income splitting flexibility) point in different directions depending on individual priorities, many incorporated business owners use a combination: a salary sufficient to achieve specific goals (maximizing RRSP room, or reaching a certain CPP contribution level), with additional compensation needs met through dividends. The specific mix depends on the individual’s retirement savings goals, views on CPP, family income-splitting situation, and the corporation’s cash flow.
This Decision Benefits From Annual Review
The optimal salary/dividend mix is not necessarily a "set once" decision — changes in personal income needs, the corporation’s profitability, RRSP room already accumulated, proximity to retirement (where CPP accrual may become more or less relevant depending on years remaining to contribute), and changes to tax rates or rules (which do occur periodically) can all shift the calculation from year to year. An annual review, ideally as part of year-end tax planning before the corporation’s fiscal year-end, allows the compensation strategy to be adjusted based on the current year’s actual results and the following year’s anticipated needs.
If you currently pay yourself entirely through dividends, entirely through salary, or have not revisited the mix in some time, this is worth reviewing — particularly in light of RRSP room, CPP considerations, and your broader retirement income plan. The "right" mix depends on your specific goals and circumstances, and often changes over time as those circumstances evolve.
