Ontario Tax Brackets for 2024

Ontario uses a progressive tax system with different rates for different income levels. The 2024 tax brackets are as follows:

Taxable Income	Tax Rate
$0 - $49,020	5.05%
$49,021 - $98,040	9.15%
$98,041 - $150,000	11.16%
$150,001 - $220,000	12.16%
$220,001 and above	13.16%

The Ontario government provides a tax calculator on their website that can help verify your calculations. However, our calculator provides a more detailed breakdown of your tax liability.

Deductions and Tax Credits

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

RRSP contributions
Medical expenses
Donations to registered charities
Home office expenses
Tuition and education expenses

Tax credits, on the other hand, directly reduce your tax payable. Examples include:

Canada Child Benefit
Ontario Trillium Benefit
Ontario Child Benefit
Ontario Disability Support Program
Ontario Homeowners' Property Tax Credit

Example Calculation

Let's walk through an example calculation for a single taxpayer with $80,000 in taxable income and no tax credits.

First bracket: $49,020 × 5.05% = $2,451.01
Second bracket: ($80,000 - $49,020) × 9.15% = $26,488.95
Total tax payable: $2,451.01 + $26,488.95 = $28,939.96

This example shows how progressive tax rates apply to different portions of your income. Our calculator can handle more complex scenarios with multiple brackets and credits.
