How Ontario Tax Refunds Work

In Ontario, tax refunds occur when the total amount of taxes withheld from your paycheck exceeds the amount you owe for the year. The refund is calculated by comparing your total tax liability to the taxes paid throughout the year.

Key Factors Affecting Your Refund

• Taxable Income: Your total income minus any deductions.
• Tax Brackets: Ontario uses progressive tax rates that increase with income.
• Deductions: Legal expenses, charitable donations, and other eligible expenses.
• Tax Credits: Amounts that reduce your tax liability directly.

Formula Used

The tax rate is determined based on your taxable income and filing status according to Ontario's 2018 tax brackets.

Worked Examples

Example 1: Single Filer

For a single filer with $50,000 taxable income and $5,000 in deductions:

1. Taxable Income = $50,000 - $5,000 = $45,000
2. Tax Rate = 20.05% (for $45,000 in Ontario 2018 brackets)
3. Tax Liability = $45,000 × 20.05% = $9,022.50
4. Assuming $10,000 in taxes paid, Estimated Refund = $10,000 - $9,022.50 = $977.50

Example 2: Married Filer

For a married filer with $80,000 taxable income and $10,000 in deductions:

1. Taxable Income = $80,000 - $10,000 = $70,000
2. Tax Rate = 26.05% (for $70,000 in Ontario 2018 brackets)
3. Tax Liability = $70,000 × 26.05% = $18,235.00
4. Assuming $20,000 in taxes paid, Estimated Refund = $20,000 - $18,235.00 = $1,765.00
