Worked Examples

Example 1: Single Person with $50,000 Income

For a single person with $50,000 total income and no additional deductions:

Taxable Income = $50,000 - $12,069 (basic personal amount) = $37,931

Tax calculation:

$44,709 × 5.05% = $2,257.75
($37,931 - $44,709) × 9.15% = $633.36
Total Provincial Tax = $2,257.75 + $633.36 = $2,891.11

Example 2: Couple with $100,000 Income

For a couple with $100,000 total income and no additional deductions:

Taxable Income = $100,000 - $24,138 (basic personal amount for couple) = $75,862

Tax calculation:

$44,709 × 5.05% = $2,257.75
($89,418 - $44,709) × 9.15% = $4,181.41
($75,862 - $89,418) × 11.16% = $1,052.84
Total Provincial Tax = $2,257.75 + $4,181.41 + $1,052.84 = $7,492.00
