How the Ontario Income Tax Calculator Works

Ontario uses a progressive tax system where your tax rate increases as your income rises. The provincial tax rates for 2023 are as follows:

Taxable Income	Tax Rate
$0 - $45,142	5.05%
$45,142.01 - $90,287	9.15%
$90,287.01 - $150,000	11.16%
$150,000.01 - $220,000	12.16%
Over $220,000	13.16%

The calculator applies these rates progressively to determine your total provincial tax. For example, income between $45,142.01 and $90,287 is taxed at 5.05% on the first $45,142 and 9.15% on the amount over $45,142.

Note: This calculator provides an estimate based on current tax rates. For exact figures, consult the Canada Revenue Agency or a tax professional.

Tax Calculation Formula

The Ontario provincial income tax is calculated using the following formula:

Provincial Tax = Sum of (Taxable Income × Rate for Each Bracket)

Where:

Taxable Income is your income after deductions
Rate for Each Bracket is the applicable tax rate for that portion of income

The calculator applies the rates progressively, meaning each portion of income is taxed at the appropriate rate for that bracket.

Worked Example

Let's calculate the provincial tax for a single filer with a taxable income of $80,000.

First $45,142 at 5.05%: $45,142 × 0.0505 = $2,283.64
Next $34,855 (from $45,142.01 to $80,000) at 9.15%: $34,855 × 0.0915 = $3,198.98
Total Provincial Tax: $2,283.64 + $3,198.98 = $5,482.62

Using the calculator with these inputs would show $5,482.62 as the provincial tax amount.
