Worked Examples
Example 1: Basic Deductions
John earns $50,000 per year. He qualifies for the Canada Employment Amount ($3,444) and the Ontario Basic Personal Amount ($11,474).
Total deductions: $3,444 + $11,474 = $14,918
Taxable income: $50,000 - $14,918 = $35,082
Example 2: With RRSP Contributions
Sarah earns $60,000 per year. She contributes 18% of her income to her RRSP ($10,800). She also qualifies for the basic deductions.
Total deductions: $3,444 (CEA) + $11,474 (Ontario) + $10,800 (RRSP) = $25,718
Taxable income: $60,000 - $25,718 = $34,282
Remember: These examples are simplified. Actual tax calculations may be more complex and depend on your specific circumstances.
