Provincial Tax = Sum of (Taxable Income × Tax Rate) for each bracket

The Basic Personal Amount is a fixed deduction that varies by filing status. For 2023, it's $12,069 for single filers and $24,138 for married filers.

Example Calculation

Let's calculate the provincial tax for a single filer with $60,000 income and $10,000 deductions:

  1. Taxable Income = ($60,000 - $10,000) - $12,069 = $37,931
  2. First $45,142 × 5.05% = $2,264.31
  3. Next $37,931 - $45,142 = $12,789 × 9.15% = $1,169.82
  4. Total Provincial Tax = $2,264.31 + $1,169.82 = $3,434.13

This example shows the progressive nature of Ontario's tax system, where higher income brackets pay higher rates.
