Worked Example

Let's calculate the tax for a single filer with $60,000 taxable income and no deductions:

Federal Tax Calculation

$45,282 × 15% = $6,792.30

($60,000 - $45,282) × 20.5% = $3,056.49

Total Federal Tax = $6,792.30 + $3,056.49 = $9,848.79

Ontario Provincial Tax Calculation

$44,753 × 5.05% = $2,261.87

($60,000 - $44,753) × 9.15% = $1,307.54

Total Provincial Tax = $2,261.87 + $1,307.54 = $3,569.41

Total Estimated Tax = $9,848.79 (federal) + $3,569.41 (provincial) = $13,418.20
