These rates apply to Ontario residents. Federal tax is not included in this calculation, but you can use our Federal Income Tax Calculator to determine your total tax liability.

Calculation Method

The Ontario annual income tax is calculated using progressive tax brackets. The formula used is:

Tax = (Income × Rate) - (Previous Bracket Threshold × Rate)

Where:

Income = Your total taxable income
Rate = The applicable tax rate for your income bracket
Previous Bracket Threshold = The upper limit of the previous tax bracket

For example, if your income is $60,000:

First $49,020 is taxed at 5.05%: $49,020 × 0.0505 = $2,499.99
Next $10,980 ($60,000 - $49,020) is taxed at 9.15%: $10,980 × 0.0915 = $1,004.93
Total tax = $2,499.99 + $1,004.93 = $3,504.92

This method ensures you pay the correct amount based on your income level.

Worked Example

Let's calculate the tax for someone earning $80,000:

First $49,020 at 5.05%: $49,020 × 0.0505 = $2,499.99
Next $48,020 ($80,000 - $49,020) at 9.15%: $48,020 × 0.0915 = $4,379.98
Total tax = $2,499.99 + $4,379.98 = $6,879.97

So, someone earning $80,000 would owe approximately $6,880 in Ontario provincial income tax.

Note: This is the provincial tax only. Federal tax would be calculated separately and added to this amount for your total tax liability.
