How overtime pay is calculated step by step
Example: Maria earns $28/hour in Ontario, works 52 hours this week.
- Regular hours: 44 hours (Ontario threshold)
- Overtime hours: 52 - 44 = 8 hours
- Regular pay: 44 × $28 = $1,232
- OT rate: $28 × 1.5 = $42/hour
- OT pay: 8 × $42 = $336
- Total gross pay: $1,232 + $336 = $1,568
- Effective hourly rate: $1,568 ÷ 52 = $30.15/hour
Overtime and taxes
While overtime is not taxed at a higher rate than regular income, your employer’s payroll system may withhold more tax from overtime-heavy paycheques. This happens because the system projects your pay period earnings across the full year and withholds accordingly.
What this means for you:
- Your overtime paycheque may appear to be taxed heavily
- At tax time, if your total annual income is lower than the projected amount, you may receive a refund
- Use our withholding tax calculator to estimate what a paycheque looks like with and without overtime
Overtime strategies for employees
- Track your hours carefully — Keep a personal log separate from your employer’s timekeeping system
- Know your province’s rules — Check whether overtime is calculated daily, weekly, or both
- Get overtime agreements in writing — If banking overtime as time off, document the arrangement
- Understand your exemption status — Not all employees are entitled to overtime pay
- Factor overtime into financial planning — Do not count on overtime as guaranteed income for budgeting purposes
