Worked Example

Let's calculate the provincial tax for a single filer with $60,000 income and $5,000 in deductions.

Taxable Income = $60,000 - $5,000 = $55,000
First $44,763 × 5.05% = $2,260.99
Next $10,237 × 9.15% = $934.88
Total Provincial Tax = $2,260.99 + $934.88 = $3,195.87

This example shows an estimated provincial tax of $3,195.87 for this scenario.
