Worked Example

Let's walk through a worked example to illustrate how tax deductions affect your Ontario salary.

Scenario

You earn a total income of $60,000 for the year. You qualify for the following deductions:

• Home office expenses: $2,000
• Charitable donations: $500
• Medical expenses: $1,000
• Union dues: $200

Step 1: Calculate Total Deductions

Total Deductions = $2,000 (home office) + $500 (charitable) + $1,000 (medical) + $200 (union) = $3,700

Step 2: Calculate Taxable Income

Taxable Income = $60,000 - $3,700 = $56,300

Step 3: Determine Tax Rate

Your taxable income of $56,300 falls into the 9.15% tax bracket.

Step 4: Calculate Tax Owed

Tax Owed = $56,300 × 9.15% = $5,134.35
