Income Tax Calculator Ontario Cra

Calculate your estimated Ontario income tax using this free online calculator. The Canada Revenue Agency (CRA) provides tax rates and brackets that change annually, so this tool uses the most recent 2023 figures. You can adjust your income, deductions, and credits to see how your tax liability changes.

How the Ontario Income Tax Calculator Works

The Ontario income tax calculator applies the progressive tax rates set by the CRA. Your taxable income is calculated by subtracting eligible deductions from your total income. The tax is then calculated based on the applicable brackets.

Formula

Taxable Income = Total Income - Deductions

Tax = Sum of (Taxable Income × Rate for each bracket)

For example, if your taxable income is $50,000, the first $44,709 is taxed at 5.05%, the next $5,292 at 9.15%, and the remaining $10,000 at 11.16%.

Worked Example

Let's calculate the tax for a single filer with $60,000 income, $5,000 in RRSP contributions, and no credits.

Taxable Income = $60,000 - $5,000 = $55,000
First $44,709 × 5.05% = $2,258.95
Next $5,292 × 9.15% = $483.19
Remaining $5,000 × 11.16% = $558.00
Total Tax = $2,258.95 + $483.19 + $558.00 = $3,300.14

Your estimated tax liability would be $3,300.14.
