2023 Ontario Tax Brackets

For the 2023 tax year, Ontario uses a progressive tax system with different tax rates for different income levels. The tax brackets for Ontario are as follows:

Note: These are the provincial tax rates. Federal tax rates are applied to the same income amount and are not included in this calculator's provincial-only estimate.

Taxable Income	Marginal 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 Ontario tax system also includes a basic personal amount that reduces your taxable income. For 2023, the basic personal amount is $12,069 for single filers and $24,138 for married filers.

How the Calculation Works

The calculator uses the following formula to estimate your Ontario provincial tax:

Ontario Tax = (Taxable Income - Basic Personal Amount) × Marginal Tax Rate

The calculator first subtracts the basic personal amount from your taxable income to determine your taxable amount. It then applies the appropriate marginal tax rate based on your taxable amount.

For example, if you earn $50,000 and are single, your taxable amount would be $50,000 - $12,069 = $37,931. This amount falls into the 9.15% tax bracket, so your Ontario tax would be $37,931 × 9.15% = $3,463.54.

Worked Example

Let's calculate the Ontario tax for a single filer with a taxable income of $60,000.

Subtract the basic personal amount: $60,000 - $12,069 = $47,931
Determine the applicable tax bracket: $47,931 falls into the 9.15% bracket
Calculate the tax: $47,931 × 9.15% = $4,383.54

Therefore, the estimated Ontario provincial tax for this filer would be $4,383.54.

Important: This calculator provides an estimate of provincial taxes only. Federal taxes are not included. For an accurate tax calculation, consult a tax professional or use official government tax software.
