Ontario Tax Calculator 2021

Calculate your Ontario provincial taxes for 2021 with this free tax calculator. Whether you're an Ontario resident or just curious about provincial tax rates, this tool provides an estimate of your tax liability based on your income.

How the Ontario Tax Calculator Works

The Ontario tax calculator estimates your provincial tax liability for 2021 using Ontario's progressive tax rates. The calculation follows these steps:

Determine your taxable income by subtracting deductions from your gross income
Apply Ontario's tax brackets to calculate provincial tax
Calculate total tax by combining provincial tax with federal tax (estimated)

Tax Calculation Formula

Provincial Tax = (Taxable Income × Ontario Tax Rate) + (Taxable Income × Federal Tax Rate)

Where Ontario Tax Rate is based on progressive brackets and Federal Tax Rate is estimated at 15% for 2021.

The calculator uses Ontario's 2021 tax rates which are progressive, meaning higher income levels are taxed at higher rates. The federal tax rate is estimated as 15% for simplicity, though actual federal tax rates may vary.

Ontario Tax Brackets for 2021

Ontario uses a progressive tax system with the following brackets for 2021:

Taxable Income	Marginal Rate
