How Ontario Income Tax Works

Ontario uses a progressive income tax system, meaning your tax rate increases as your income rises. The province also has a number of deductions and credits that can reduce your taxable income.

Ontario Income Tax = (Taxable Income × Progressive Tax Rate) - (Deductions + Credits)

Key Components of Ontario Income Tax

Taxable Income: Your total income minus deductions and credits
Progressive Tax Rates: Different rates apply to different income brackets
Deductions: Expenses you can subtract from your income
Credits: Amounts that directly reduce your tax liability

The Ontario government provides several types of credits, including the Ontario Child Benefit, Ontario Trillium Benefit, and Ontario Disability Support Program. These can significantly reduce your tax liability.
