Two ways money leaves the corporation
Once you own a corporation, the profit does not belong to you until the corporation pays it out. Salary is paid to you as an employee: it is a deductible expense to the corporation, it runs through payroll with source deductions, and it is reported on a T4 slip. A dividend is paid to you as a shareholder: it is not deductible to the corporation, it is paid from after-tax profit, and it is reported on a T5 slip.
Both approaches end with personal tax on what you receive. Under the integration principle, the combined corporate and personal tax on a dividend is intended to be roughly comparable to the tax on the same amount paid as salary. In practice the two are rarely identical, and the differences in a given year depend on the corporation’s rate, your other income and the province. That is why there is no single correct answer and why the mix is worth revisiting as circumstances change.
Canada Pension Plan contributions
Salary is pensionable employment. The CRA’s payroll guidance requires the employer to deduct CPP contributions from an employee who is between 18 and 69 and in pensionable employment, and to contribute an equal amount. For an owner-manager, both halves come out of the same pocket, and since 2024 a second additional contribution applies on earnings between the first and second earnings ceilings.
Dividends are not pensionable earnings, so no CPP contributions are made on them. Some owners see that as a cost avoided; others see it as retirement income and disability coverage forgone. The right view depends on your age, your other retirement savings and how you value a predictable indexed pension. Treat CPP as a benefit with a price rather than simply a tax.
RRSP room and other salary-linked items
The CRA calculates RRSP deduction room from earned income in the previous year, at 18% up to the annual limit, less any pension adjustment. Salary is earned income for this purpose; dividends are not. An owner paid entirely by dividend therefore builds no new RRSP room. If tax-sheltered retirement savings are part of your plan, some salary is usually needed to generate the room.
Salary also supports other calculations that use employment income, such as the amount of childcare expense you can claim, and a lender may find a T4 easier to assess than dividend history. Against that, salary requires a payroll account, regular remittances and a T4 filing, which is administrative work the corporation must do correctly and on time.
What dividends change
Because dividends are paid from after-tax profit, they interact with the corporation’s own tax. Dividends paid from income taxed at the small business rate are treated differently on your personal return from dividends paid from income taxed at the general rate, which is how the system attempts to integrate the two levels. The corporation must track which type it is paying and report it correctly on the T5.
Dividends can be declared without payroll, which is administratively simpler, but they must still be properly authorized by the directors and documented in the corporate records. Paying a family member dividends attracts specific rules on split income, so do not assume income can be shared with a spouse or adult child without advice.
How to approach the decision
Start with what you need to live on, then what the corporation can afford to retain. Layer in your retirement plan, whether you want CPP and RRSP room, any borrowing on the horizon, and the corporation’s tax position for the year. Many owners end up with a mix: enough salary to reach a chosen CPP or RRSP target, with dividends for the remainder.
Review the mix each year before the fiscal year-end, while there is still time to run a bonus through payroll or declare a dividend in the right period. Whatever you decide, keep the paperwork consistent: payroll remittances and T4s for salary, director resolutions and T5s for dividends, and shareholder loan records for anything drawn in between.
Your conversation checklist
- Personal cash needs for the coming year
- Profit the corporation can retain
- Your age and existing CPP contribution history
- RRSP room you want to create
- Planned borrowing that will require income proof
- Family members who might receive income
- Payroll account status and remitting frequency
- Shareholder loan balance at year-end
