Worked Example

Let's calculate the Ontario income tax for someone with $95,000 in taxable income.

First $44,701 at 5.05%: $44,701 × 0.0505 = $2,266.76
Next $44,703 ($89,404 - $44,701) at 9.15%: $44,703 × 0.0915 = $4,080.86
Remaining $5,596 ($95,000 - $89,404) at 11.16%: $5,596 × 0.1116 = $623.38

Total Ontario income tax: $2,266.76 + $4,080.86 + $623.38 = $6,971.00
