Worked Example

Let's calculate the tax for a single person with an annual income of $60,000.

First $49,020 taxed at 5.05%: $49,020 × 0.0505 = $2,479.59
Next $10,980 ($60,000 - $49,020) taxed at 9.15%: $10,980 × 0.0915 = $1,005.33
Total tax: $2,479.59 + $1,005.33 = $3,484.92

So, a single person earning $60,000 would owe approximately $3,485 in Ontario income tax.
