Formula Used

Ontario Tax Calculation Formula

The calculator uses Ontario's progressive tax brackets to calculate your provincial tax liability. The formula is:

Provincial Tax = (Taxable Income × Tax Rate) - Tax Credits

Where Tax Rate is determined by your taxable income and filing status according to Ontario's tax tables.

For example, a single filer with $50,000 in taxable income would pay approximately $4,500 in provincial taxes before credits.

Worked Example

Let's calculate the provincial tax for a single filer with $60,000 in taxable income and no tax credits:

First 44,753 of income is taxed at 5.05%: $44,753 × 0.0505 = $2,266.44
Next 44,753 of income is taxed at 9.15%: $44,753 × 0.0915 = $4,070.96
Remaining $10,494 is taxed at 11.16%: $10,494 × 0.1116 = $1,165.55
Total provincial tax: $2,266.44 + $4,070.96 + $1,165.55 = $7,502.95

This single filer would owe approximately $7,503 in provincial taxes before any credits.

Interpreting Your Results

Your tax return Ontario calculator results will show either:
