2023 Ontario Tax Calculator

Use our 2023 Ontario Tax Calculator to estimate your provincial income tax liability. This calculator uses the 2023 Ontario tax rates and brackets to provide an accurate estimate of your tax obligation. It's important to note that this is an estimate and your actual tax liability may vary based on your specific circumstances.

How the 2023 Ontario Tax Calculator Works

The 2023 Ontario Tax Calculator uses progressive tax brackets to determine your provincial income tax. Here's how it works:

Tax Calculation Formula

Ontario income tax is calculated using progressive tax brackets. The formula is:

Tax = (Income × Rate) - Deductions + Credits

Where:

Income is your total taxable income
Rate is the applicable tax bracket rate
Deductions are any eligible tax deductions
Credits are any eligible tax credits

The calculator applies the 2023 Ontario tax rates to your income, subtracts any eligible deductions, and adds any eligible credits to determine your estimated tax liability.

2023 Ontario Tax Brackets

For 2023, Ontario uses the following progressive tax rates:

Taxable Income	Marginal 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%
$220,000.01+	13.16%

These rates apply to Ontario residents. The Ontario government may adjust these rates in future years, so it's important to check for updates.

Worked Examples

Let's look at two examples to illustrate how the calculator works.

Example 1: Single filer with $50,000 income

For a single filer with $50,000 taxable income:

First $45,142 is taxed at 5.05%: $45,142 × 0.0505 = $2,274.33
Next $4,858 ($50,000 - $45,142) is taxed at 9.15%: $4,858 × 0.0915 = $442.59
Total tax: $2,274.33 + $442.59 = $2,716.92

Example 2: Single filer with $100,000 income

For a single filer with $100,000 taxable income:

First $45,142 is taxed at 5.05%: $45,142 × 0.0505 = $2,274.33
Next $45,145 ($90,287 - $45,142) is taxed at 9.15%: $45,145 × 0.0915 = $4,124.58
Next $9,713 ($100,000 - $90,287) is taxed at 11.16%: $9,713 × 0.1116 = $1,088.12
Total tax: $2,274.33 + $4,124.58 + $1,088.12 = $7,487.03
