($50,000 - $44,703) × 9.15% = $528.28

Example Calculation

Let's calculate the Ontario provincial tax for a single filer with a taxable income of $80,000 in 2021.

First $44,703 × 5.05% = $2,261.72
Next $44,704 ($80,000 - $44,703) × 9.15% = $4,078.28
Total Ontario Tax = $2,261.72 + $4,078.28 = $6,340.00

Therefore, a single filer with $80,000 in taxable income would owe approximately $6,340 in Ontario provincial tax for the 2021 tax year.
