Worked Example

Let's calculate the tax for a single filer with $60,000 in taxable income and no additional deductions or credits.

Calculation Steps

Federal tax: 15% of $40,922 + 22% of ($60,000 - $40,922) = $1,975 + $3,850 = $5,825
Ontario tax: 15% of $40,922 + 20% of ($60,000 - $40,922) = $1,975 + $3,273 = $5,248
Total tax: $5,825 (federal) + $5,248 (Ontario) = $11,073
Effective tax rate: ($11,073 / $60,000) × 100 = 18.46%

This example shows that a single filer with $60,000 in taxable income would owe approximately $11,073 in taxes for 2012.
