Worked Example

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

Example Calculation

1. First $45,142: $45,142 × 5.05% = $2,267.84

2. Next $14,858 ($60,000 - $45,142): $14,858 × 9.15% = $1,359.46

3. Total tax: $2,267.84 + $1,359.46 = $3,627.30

This example shows how the progressive tax system works. The first portion of income is taxed at a lower rate, while higher portions are taxed at progressively higher rates.
