Worked Examples

Example 1: Single filer with $50,000 income

Taxable income: $50,000 - $0 (no deductions) = $50,000

Provincial tax: $50,000 × 5.05% = $2,525

Final tax: $2,525 - $0 (no credits) = $2,525

Example 2: Married filer with $100,000 income and $10,000 RRSP contribution

Taxable income: $100,000 - $10,000 = $90,000

Provincial tax: $90,000 × 9.15% = $8,235

Final tax: $8,235 - $0 (no credits) = $8,235
