What salary gives you that dividends do not
A salary is deductible to the corporation, so it reduces corporate taxable income dollar for dollar. It also does three things dividends cannot:
- Creates RRSP contribution room at 18% of earned income, up to the annual limit
- Builds CPP entitlement toward your future pension
- Counts as earned income for childcare deductions and certain other credits
The cost is administration: salary requires a payroll account, source deduction remittances by the 15th of each month, and T4 slips by the end of February. It also triggers CPP contributions from both the employee and employer side.
