Ontario Income Tax Rate Calculator

Use this Ontario Income Tax Rate Calculator to determine your effective tax rate based on your annual income. The calculator provides a detailed breakdown of how much tax you'll owe and what percentage of your income is going to taxes.

How Ontario Income Tax Works

Ontario's income tax system is progressive, meaning higher incomes are taxed at higher rates. The province uses a combination of federal and provincial tax rates to determine your total tax liability.

Key Formula

Ontario income tax is calculated by applying the progressive tax rates to your taxable income. The formula is:

Tax Owed = (Income × Federal Tax Rate) + (Income × Ontario Tax Rate)

Where taxable income is your total income minus deductions and credits.

Ontario residents are subject to both federal and provincial taxes. The federal government handles basic income tax, while Ontario adds its own rates on top of that. This means your total tax bill is the sum of both federal and provincial taxes.

Note: This calculator uses the 2023 tax rates. For the most current rates, check the Canada Revenue Agency website.

Ontario Tax Brackets

Ontario's tax brackets are progressive, meaning higher incomes are taxed at higher rates. Here are the current tax brackets for 2023:

Taxable Income	Federal Rate	Ontario Rate	Combined Rate
$0 - $50,197	15%	5.05%	20.05%
$50,197 - $100,392	20.5%	9.15%	29.65%
$100,392 - $155,625	26%	11.16%	37.16%
$155,625 - $220,000	29%	12.16%	41.16%
$220,000+	33%	13.16%	46.16%

The combined rate shows what percentage of your income goes to taxes. For example, someone earning $50,000 would pay about 20.05% in combined federal and provincial taxes.

Example Calculation

Let's calculate the tax for someone earning $75,000 in Ontario:

First $50,197 is taxed at 20.05%: $50,197 × 0.2005 = $10,059.54
Next $24,803 ($75,000 - $50,197) is taxed at 29.65%: $24,803 × 0.2965 = $7,372.31
Total tax owed: $10,059.54 + $7,372.31 = $17,431.85
Effective tax rate: ($17,431.85 / $75,000) × 100 = 23.24%

This example shows that someone earning $75,000 would pay $17,431.85 in combined federal and provincial taxes, resulting in an effective tax rate of 23.24%.
