Ontario taxes are calculated based on your income, deductions, and credits. This calculator helps you estimate your provincial income tax, Canada Pension Plan (CPP) contributions, Employment Insurance (EI) premiums, and net pay after taxes.
How Ontario Taxes Work
Ontario uses a progressive tax system, meaning your tax rate increases as your income rises. The provincial government collects taxes through payroll deductions, income tax returns, and other sources.
Taxable Income = Gross Income - Deductions
Provincial Tax = Taxable Income × Provincial Tax Rate
Your net pay after taxes is calculated by subtracting provincial income tax, CPP contributions, and EI premiums from your gross income.
Tax Brackets in Ontario
As of 2023, Ontario's provincial tax rates are as follows:
| Taxable Income | Marginal Rate |
|---|---|
| $0 - $45,142 | 5.05% |
| $45,142.01 - $90,287 | 9.15% |
| $90,287.01 - $150,000 | 11.16% |
| $150,000.01 - $220,000 | 12.16% |
| Over $220,000 | 13.16% |
Federal tax rates are calculated separately and added to the provincial tax to determine your total income tax.
