Tax Calculation Formula
The Ontario tax calculation follows a progressive tax system with multiple brackets. The formula used is:
Tax = (Income × Tax Rate) - Tax Credit
Where Tax Rate is determined by your income bracket and Tax Credit is the Ontario tax credit amount.
The Ontario tax brackets for 2023 are as follows:
| Income Range | Tax Rate |
|---|---|
| $0 - $44,703 | 5.05% |
| $44,704 - $89,407 | 9.15% |
| $89,408 - $150,000 | 11.16% |
| $150,001 - $220,000 | 12.16% |
| Over $220,000 | 13.16% |
Assumptions and Limitations
This calculator makes the following assumptions:
- Single tax filing status

This calculator provides an estimate only. Actual tax liability may vary based on your specific circumstances and may be subject to changes in tax laws.
Worked Example
Let's calculate the provincial tax for someone earning $60,000 annually:
- Determine the applicable tax brackets:
- $0 - $44,703 at 5.05%
- $44,704 - $60,000 at 9.15%
- Calculate tax for the first bracket: $44,703 × 5.05% = $2,261.72
- Calculate tax for the second bracket: ($60,000 - $44,703) × 9.15% = $13,286.28
- Total tax before credits: $2,261.72 + $13,286.28 = $15,548.00
- Subtract Ontario tax credit (approximately $1,500): $15,548.00 - $1,500 = $14,048.00
The estimated provincial tax for $60,000 income is $14,048.00.
