Worked Example

Let's calculate the tax for a single person with a gross income of $50,000:

1. Federal Tax:
   • $48,535 × 15% = $7,280.25
   • $1,465 × 20.5% = $300.68
   • Total Federal Tax = $7,580.93
2. Provincial Tax:
   • $44,771 × 5.05% = $2,269.36
   • $5,229 × 9.15% = $479.37
   • Total Provincial Tax = $2,748.73
3. Total Tax = $7,580.93 + $2,748.73 = $10,329.66
4. Net Income = $50,000 - $10,329.66 = $39,670.34
5. Effective Tax Rate = ($10,329.66 / $50,000) × 100% = 20.66%

This example shows that a single person earning $50,000 would pay approximately $10,330 in taxes, leaving them with about $39,670 in net income.
