How the Overtime Tax Rate Calculator Works
Overtime pay in Ontario is subject to the same tax rates as regular pay, but there are specific rules about how overtime is calculated and taxed. This calculator helps you determine your effective overtime tax rate based on your regular pay and overtime hours.
Key Assumptions
- Overtime is calculated at 1.5 times your regular hourly rate
- All pay is subject to Ontario's provincial tax rates
- No deductions for CPP, EI, or other benefits
- Tax rates are based on 2023 Ontario tax tables
Formula Used
Effective Overtime Tax Rate = (Total Tax Paid) / (Total Overtime Pay) × 100%
Where:
- Total Tax Paid = (Regular Pay + Overtime Pay) × Tax Rate
- Regular Pay = Regular Hours × Hourly Rate
- Overtime Pay = Overtime Hours × (Hourly Rate × 1.5)
How to Use the Overtime Tax Rate Calculator
- Enter your regular hourly wage in the "Hourly Rate" field
- Enter the number of regular hours worked in the "Regular Hours" field
- Enter the number of overtime hours worked in the "Overtime Hours" field
- Click "Calculate" to see your results
- Review the breakdown of your earnings and taxes
Ontario Tax Rates for Overtime Pay
In Ontario, overtime pay is taxed at the same progressive rates as regular pay. The current tax brackets for 2023 are:
| Taxable Income | Tax Rate |
|---|---|
| $0 - $44,703 | 20.05% |
| $44,704 - $89,407 | 24.19% |

Example Calculation
Let's say you earn $20/hour and work 40 regular hours plus 10 overtime hours:
Example Breakdown
- Regular Pay: 40 × $20 = $800
- Overtime Pay: 10 × ($20 × 1.5) = $300
- Total Pay: $800 + $300 = $1,100
- Tax Rate: 24.19% (since $1,100 falls in the $44,704-$89,407 bracket)
- Tax Paid: $1,100 × 24.19% = $266.09
- Effective Overtime Tax Rate: ($266.09 / $300) × 100% = 88.7%
This means you're effectively paying 88.7% in taxes on your overtime earnings in this scenario.
