2023 Ontario Tax Brackets
Ontario uses a progressive tax system with different rates for different income levels. Here are the 2023 tax brackets:
| Taxable Income | Tax Rate |
|---|---|
| $0 - $45,142 | 5.05% |
| $45,142.01 - $90,287 | 9.15% |
| $90,287.01 - $102,253 | 11.16% |
| $102,253.01 - $150,000 | 12.16% |
| $150,000.01 - $220,000 | 13.16% |
| $220,000.01+ | 16.52% |
The tax rate increases as your taxable income increases, creating a progressive tax system.
