Example Calculation

Let's calculate the taxes for someone earning $60,000 in Ontario:

Subtract the Basic Personal Amount: $60,000 - $12,069 = $47,931
Calculate Ontario tax:
- $48,535 × 5.05% = $2,448.94
- ($47,931 - $48,535) × 9.15% = $0
- Total Ontario tax = $2,448.94
Calculate CPP and EI:
- CPP: $60,000 × 5.7% = $3,420
- EI: $60,000 × 1.66% = $996
Total deductions = $2,448.94 (Ontario) + $3,420 (CPP) + $996 (EI) = $6,864.94
Net income = $60,000 - $6,864.94 = $53,135.06

Formula: Net Income = Gross Income - (Ontario Tax + CPP + EI)
