Where the brackets and rates are based on the 2011 tax tables. The calculator applies the appropriate brackets based on your filing status.

Worked Example

Let's calculate the tax for a single filer with $50,000 taxable income in 2011.

Example Calculation

Federal Tax: $10,000 × 15% + ($50,000 - $10,000) × 28% = $1,500 + $10,400 = $11,900

Provincial Tax: $10,000 × 10% + ($50,000 - $10,000) × 12% = $1,000 + $4,800 = $5,800

Total Tax: $11,900 + $5,800 = $17,700

This example uses simplified rates. The actual calculation may vary based on the official 2011 tax tables.
