Calculating overtime tax in Ontario requires understanding both the overtime pay structure and the provincial tax rates. This guide explains how to determine taxable overtime earnings and apply the correct tax deductions.
What is Overtime Tax?
Overtime tax refers to the income tax withheld from overtime pay. In Ontario, overtime is calculated based on hours worked beyond the standard 40-hour workweek. The tax on overtime is calculated using the same tax rates as regular pay, but it's important to track overtime separately for tax purposes.

How Overtime Is Calculated
Overtime is calculated based on the number of hours worked beyond the standard 40-hour workweek. In Ontario, the standard overtime rate is 1.5 times the regular hourly wage for hours worked between 40 and 50 in a workweek. For hours worked beyond 50, the rate increases to 2 times the regular hourly wage.
Overtime Pay Formula:
Regular Pay = Hourly Wage × 40 hours
Overtime Pay = (Hourly Wage × 1.5) × (Total Hours - 40) if 40 < Total Hours ≤ 50
Overtime Pay = (Hourly Wage × 2) × (Total Hours - 50) if Total Hours > 50
Ontario Tax Rates
Ontario has progressive income tax rates that apply to both regular pay and overtime. The tax rates are as follows:
- 0% on the first $44,701 of taxable income
- 5.05% on the next $44,700 (taxable income between $44,701 and $89,400)
- 9.15% on the next $55,200 (taxable income between $89,401 and $144,600)
- 11.16% on the next $66,300 (taxable income between $144,601 and $210,900)
- 12.16% on the next $110,400 (taxable income between $210,901 and $321,300)
- 13.16% on taxable income over $321,300
These rates are subject to change, so it's important to verify them with the latest tax tables from the Canada Revenue Agency.
Calculating Overtime Tax
To calculate overtime tax, follow these steps:
- Calculate your total taxable income including overtime pay.
- Determine which tax bracket your total income falls into.
- Calculate the tax owed on the overtime portion using the applicable tax rate.
Overtime Tax Formula:
Overtime Tax = Overtime Pay × Applicable Tax Rate
For example, if your overtime pay is $100 and falls into the 5.05% tax bracket, your overtime tax would be $5.05.
Example Calculation
Let's say you earn $20 per hour and work 45 hours in a week. Here's how to calculate your overtime tax:
- Regular Pay = $20 × 40 = $800
- Overtime Pay = ($20 × 1.5) × (45 - 40) = $30 × 5 = $150
- Total Income = $800 + $150 = $950
- Assuming your total taxable income is $950 and falls into the 5.05% tax bracket, your overtime tax would be $150 × 5.05% = $7.58
This is a simplified example. Actual tax calculations may be more complex depending on your total taxable income and deductions.
Common Mistakes
When calculating overtime tax, common mistakes include:
- Not tracking overtime separately from regular pay
- Using the wrong overtime rate (1.5x or 2x)
- Applying the wrong tax bracket to overtime pay
- Forgetting to account for all taxable income
To avoid these mistakes, keep detailed records of your hours worked and use tax software or consult a tax professional if needed.
Next Steps
After calculating your overtime tax, consider these next steps:
- Review your pay stub to ensure overtime is correctly calculated and taxed
- Keep records of your hours worked and overtime pay for tax season
- Consult a tax professional if you have complex tax situations
- Stay updated on changes to Ontario's tax rates and overtime regulations
