Canada Ontario Tax Rate Calculator

Calculate your Ontario provincial income tax with this free tax rate calculator. Ontario uses a progressive tax system with multiple brackets, and this tool provides accurate estimates for 2024. Whether you're an Ontario resident or planning to move there, this calculator helps you understand your tax liability.

How the Ontario Tax Calculator Works

The Ontario tax calculator uses the province's progressive tax system to determine your income tax liability. Ontario has a flat tax rate of 5.05% on the first $44,771 of taxable income, with higher rates applying to amounts above this threshold.

Formula Used

Ontario Income Tax = (Taxable Income × 5.05%) if Taxable Income ≤ $44,771

Ontario Income Tax = ($44,771 × 5.05%) + [(Taxable Income - $44,771) × 12.16%] if Taxable Income > $44,771

The calculator applies the Ontario tax rates to your reported income, then provides a detailed breakdown of your tax liability. This includes the provincial tax amount, federal tax amount (if applicable), and total tax payable.
