Worked Example

Let's calculate the Ontario income tax for a single filer with a taxable income of $60,000.

The first $44,703 is taxed at 5.05%: $44,703 × 0.0505 = $2,269.47
The next $15,297 ($60,000 - $44,703) is taxed at 9.15%: $15,297 × 0.0915 = $1,399.08
Total tax owed: $2,269.47 + $1,399.08 = $3,668.55

Using the calculator, you would enter $60,000 as the taxable income and select "Single" as the filing status to get this result.
