Reviewed by Calculator Editorial Team

Ontario income tax is calculated based on your taxable income after deductions. This calculator helps you estimate your Ontario tax liability for the current tax year.

How to Calculate Ontario Tax

The Ontario government uses a progressive tax system where different income brackets are taxed at different rates. Here's how the calculation works:

  1. Calculate your total income for the year
  2. Subtract eligible deductions to find your taxable income
  3. Apply the Ontario tax rates to your taxable income
  4. Subtract any tax credits to get your final tax liability

Note: This calculator provides an estimate. Your actual tax liability may differ based on your specific circumstances and changes to tax laws.

Ontario Tax Brackets

For the 2023 tax year, Ontario uses the following tax brackets:

Taxable Income Tax Rate
$0 - $45,142 5.05%
$45,142.01 - $90,281 9.15%
$90,281.01 - $102,763 11.16%
$102,763.01 - $200,000 12.16%
$200,000.01 and over 13.16%
Ontario Tax = (Taxable Income × Rate) + (Taxable Income - Bracket Threshold × Higher Rate)

Deductions and Tax Credits

Several deductions and credits can reduce your taxable income or lower your tax bill:

Common Deductions

  • RRSP contributions
  • Medical expenses
  • Donations to registered charities
  • Home office expenses
  • Union dues

Common Tax Credits

  • Canada Child Benefit
  • Canada Pension Plan contributions
  • Employment Insurance premiums
  • Provincial sales tax credits

Example Calculation

Let's calculate the Ontario tax for someone with $80,000 in taxable income:

  1. $0 - $45,142 at 5.05% = $2,264.23
  2. $45,142.01 - $80,000 at 9.15% = $3,131.39
  3. Total Ontario tax = $2,264.23 + $3,131.39 = $5,395.62

After applying any eligible tax credits, the final tax liability would be less.
