Worked Example

Let's calculate payroll taxes for an employee with a gross pay of $3,000 in Ontario.

1. Gross Pay: $3,000
2. Income Tax: $500 (based on applicable tax brackets)
3. CPP: $154.50 (employer) + $154.50 (employee)
4. EI: $48.64 (employer)
5. Ontario Health Tax: $79.50 (employer) + $79.50 (employee)
6. Deductions: $200 (union dues)
7. Net Pay: $3,000 - ($500 + $154.50 + $154.50 + $48.64 + $79.50 + $79.50 + $200) = $1,462.46
