Example Calculation

Let's calculate the provincial income tax for someone with $80,000 gross income and $10,000 in deductions:

Worked Example

1. Taxable income = $80,000 - $10,000 = $70,000

2. Tax calculation:

$48,535 × 5.05% = $2,443.94
($70,000 - $48,535) × 9.15% = $1,728.11
Total tax = $2,443.94 + $1,728.11 = $4,172.05
