How Ontario Taxes Are Calculated
Ontario's provincial tax system uses a progressive tax rate structure. The basic formula is:
Ontario Tax = (Taxable Income × Progressive Rate) - Deductions/Credits
The progressive rates for 2023 are:
| Taxable Income | Progressive 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% |
The calculator applies these rates based on your taxable income and filing status.
Worked Examples
Example 1: Single Filer with $50,000 Income
For a single filer with $50,000 taxable income:
- First $45,142 at 5.05% = $2,264.23
- Remaining $4,858 at 9.15% = $444.23
- Total tax = $2,264.23 + $444.23 = $2,708.46
Example 2: Married Filers with $120,000 Income
For married filers with $120,000 taxable income:
- First $45,142 at 5.05% = $2,264.23
- Next $45,145 at 9.15% = $4,117.48
- Remaining $29,713 at 11.16% = $3,312.86
