How the 2025 Ontario Tax Calculator Works

The calculator uses the 2025 Ontario tax rates and federal tax rates to compute your estimated tax liability. It accounts for both provincial and federal taxes, which are calculated on your taxable income after deductions.

Tax Calculation Formula

Taxable Income = Gross Income - Deductions

Provincial Tax = Taxable Income × Ontario Tax Rate

Federal Tax = Taxable Income × Federal Tax Rate

Total Tax = Provincial Tax + Federal Tax

Worked Examples

Example 1: Single Taxpayer

For a single taxpayer with $60,000 gross income and $10,000 in deductions:

Taxable Income = $60,000 - $10,000 = $50,000

Provincial Tax = $50,000 × 9.15% = $4,575

Federal Tax = $50,000 × 15% = $7,500

Total Tax = $4,575 + $7,500 = $12,075

Example 2: Married Couple

For a married couple with $120,000 combined gross income and $20,000 in deductions:

Taxable Income = $120,000 - $20,000 = $100,000

Provincial Tax = $100,000 × 11.16% = $11,160

Federal Tax = $100,000 × 20.5% = $20,500

Total Tax = $11,160 + $20,500 = $31,660
