How Is Tax Calculated in Ontario

Reviewed by Calculator Editorial Team

Ontario's income tax system is progressive, meaning higher-income earners pay a higher percentage of their income in taxes. This guide explains how Ontario calculates income tax, including tax brackets, deductions, and credits. Our calculator helps you estimate your tax liability based on your income and filing status.

How Ontario Tax Works

Ontario's income tax system is based on a progressive tax rate structure, which means that as your income increases, so does your tax rate. The province also offers various deductions and credits to help reduce your taxable income.

Taxable Income

Your taxable income is calculated by subtracting deductions from your total income. The basic personal amount (BPA) is a fixed amount that reduces your taxable income. For 2023, the BPA for individuals is $12,069.

Taxable Income Formula

Taxable Income = Total Income - Deductions - Basic Personal Amount (BPA)

Progressive Tax Rates

Ontario uses a progressive tax rate system, which means your tax rate increases as your taxable income increases. The tax rates for 2023 are as follows:

Taxable Income Tax Rate
$0 - $48,535 5.05%
$48,535.01 - $97,069 9.15%
$97,069.01 - $150,473 11.16%
$150,473.01 - $220,000 12.16%
Over $220,000 13.16%

Example Calculation

Let's say you have a total income of $60,000 and no additional deductions. Your taxable income would be:

Taxable Income = $60,000 - $0 (deductions) - $12,069 (BPA) = $47,931

Your tax liability would be calculated as follows:

Bracket Taxable Income Tax Rate Tax Amount
1 $47,931 5.05% $2,400.28

So, your total tax liability would be $2,400.28.

Ontario Tax Brackets

The Ontario tax brackets are designed to ensure that higher-income earners contribute a larger portion of their income to the provincial treasury. The brackets are as follows:

Taxable Income Tax Rate
$0 - $48,535 5.05%
$48,535.01 - $97,069 9.15%
$97,069.01 - $150,473 11.16%
$150,473.01 - $220,000 12.16%
Over $220,000 13.16%

For example, if your taxable income is $100,000, you would pay taxes at the following rates:

Bracket Taxable Income Tax Rate Tax Amount
1 $48,535 5.05% $2,446.38
2 $48,464 ($100,000 - $48,535) 9.15% $4,433.81
Total $6,880.19

  • Basic Personal Amount (BPA): A fixed amount that reduces your taxable income.
