Worked Examples

Example 1: Single filer with $50,000 gross income

Taxable income: $50,000 - $12,000 (basic personal amount) = $38,000

Tax calculation:

$45,142 × 5.05% = $2,263.33
($38,000 - $45,142) × 9.15% = $676.67
Total tax = $2,263.33 + $676.67 = $2,940.00

Take-home pay: $50,000 - $2,940 = $47,060

Example 2: Family with $120,000 gross income and $20,000 in RRSP contributions

Taxable income: $120,000 - $20,000 (RRSP) - $24,000 (basic personal amount) = $76,000

Tax calculation:

$45,142 × 5.05% = $2,263.33
($90,287 - $45,142) × 9.15% = $4,186.67
($76,000 - $90,287) × 11.16% = $953.33
Total tax = $2,263.33 + $4,186.67 + $953.33 = $7,403.33

Take-home pay: $120,000 - $7,403.33 = $112,596.67
