Worked Example

Let's calculate the Ontario provincial tax for a married couple with a combined income of $120,000.

Identify the applicable tax bracket: $102,253.01 - $150,000 at 12.16%
Calculate the taxable amount in this bracket: $120,000 - $102,253 = $17,747
Calculate the tax for this portion: $17,747 × 12.16% = $2,152.66
Add the tax from previous brackets:
- $45,142 × 5.05% = $2,264.33
- $45,145 × 9.15% = $4,117.68
- $9,970 × 11.16% = $1,110.34
Total Ontario tax: $2,264.33 + $4,117.68 + $1,110.34 + $2,152.66 = $9,545.01

This example shows how the progressive tax system applies different rates to different portions of your income.
