Whether you're an employee, self-employed, or investor, this tool helps you understand your tax liability and plan accordingly.

How the Ontario Income Tax Calculator Works

The Ontario income tax calculator uses progressive tax brackets to determine your tax liability. Here's how it works:

Enter your total taxable income for the year
Select your filing status (Single, Married, or Other)
The calculator applies Ontario's tax rates to each bracket of your income
It subtracts any applicable deductions and credits
Finally, it calculates your estimated tax liability

Formula Used

Ontario income tax = (Income × Tax Rate) - Deductions + Credits

This progressive taxation system means higher-income earners pay a higher percentage of their income in taxes than lower-income earners.
