Ontario Tax Brackets

Ontario uses a progressive tax system with different rates for different income levels. The current tax brackets for 2023 are shown in the table below:

How Ontario Income Tax Works

Ontario's income tax system is progressive, meaning higher-income individuals pay a higher percentage of their income in taxes. The tax is calculated by applying the appropriate rate to each portion of your income that falls within a specific bracket.

The calculation process involves:

1. Determining your taxable income after deductions
2. Applying the appropriate tax rate to each income bracket
3. Subtracting any tax credits or deductions
4. Calculating the final tax liability

For example, someone earning $50,000 would pay 5.05% on the first $48,535 and 9.15% on the remaining $1,465, resulting in a total tax liability of approximately $3,200.
