Calculate your Ontario income tax obligation with this free online calculator. Simply enter your taxable income and deductions to determine your estimated tax liability based on current Ontario tax rates.

How the Ontario Income Tax Calculator Works

The Ontario income tax calculator applies progressive tax rates to your taxable income. This means higher income brackets are taxed at higher rates. The calculator accounts for federal and provincial tax rates, as well as common deductions.

Formula Used

Taxable Income = Gross Income - Deductions
Federal Tax = Taxable Income × Federal Tax Rate
Provincial Tax = Taxable Income × Provincial Tax Rate
Total Tax = Federal Tax + Provincial Tax

Ontario uses a marginal tax system where each dollar of income is taxed at the rate applicable to that portion of income. For example, if your taxable income is $50,000, the first $44,708 is taxed at 20.5%, the next $5,292 at 26%, and the remaining $4,900 at 29%.
