Calculate Income Tax Payable Ontario

Calculating your Ontario income tax payable is essential for understanding your tax liability and planning your finances. This guide explains the Ontario tax system, provides a step-by-step calculation method, and includes a free online calculator to determine your tax payable.

How to Calculate Ontario Income Tax

The Ontario government uses a progressive tax system, meaning your tax rate increases as your income rises. The calculation involves several steps, including determining your taxable income, applying the appropriate tax brackets, and accounting for deductions and credits.

Step 1: Determine Your Taxable Income

Your taxable income is calculated by subtracting eligible deductions from your total income. Common deductions include RRSP contributions, union dues, and medical expenses. The Ontario government provides a list of approved deductions on its official website.

Step 2: Apply Ontario Tax Brackets

Once you have your taxable income, you can apply the Ontario tax brackets to calculate your tax payable. The Ontario tax system has five progressive tax brackets, as shown in the table below.

Taxable Income	Tax Rate
$0 - $45,142	5.05%
$45,142.01 - $90,287	9.15%
$90,287.01 - $109,350	11.16%
$109,350.01 - $200,000	12.16%
Over $200,000	13.16%

Step 3: Calculate Your Tax Payable

To calculate your tax payable, multiply each portion of your taxable income by its corresponding tax rate and sum the results. For example, if your taxable income is $50,000, you would calculate:

Tax Calculation Formula

Tax Payable = (Taxable Income × Tax Rate) + (Remaining Taxable Income × Next Tax Rate)

This process ensures you pay the correct amount of tax based on your income level.

Ontario Tax Brackets

The Ontario tax system uses progressive tax brackets, which means higher-income individuals pay a higher percentage of their income in taxes. The current Ontario tax brackets are as follows:

Taxable Income	Tax Rate	Marginal Rate
$0 - $45,142	5.05%	5.05%
$45,142.01 - $90,287	9.15%	4.10%
$90,287.01 - $109,350	11.16%	2.01%
$109,350.01 - $200,000	12.16%	1.00%
Over $200,000	13.16%	1.00%

The marginal rate shows the additional tax rate applied to each dollar of income in that bracket. For example, in the $45,142.01 - $90,287 bracket, the marginal rate is 4.10%, meaning each additional dollar earned in this range is taxed at 4.10%.

Note

Tax brackets are subject to change. Always verify the current tax rates with the Ontario government before calculating your tax payable.

Example Calculation

Let's walk through an example to illustrate how to calculate Ontario income tax. Suppose you have a taxable income of $60,000.

Step 1: Apply the First Tax Bracket

The first $45,142 is taxed at 5.05%.

$45,142 × 5.05% = $2,274.89

Step 2: Apply the Second Tax Bracket

The next $14,858 ($60,000 - $45,142) is taxed at 9.15%.

$14,858 × 9.15% = $1,359.31

Step 3: Sum the Taxes

Add the taxes from both brackets to get the total tax payable.

$2,274.89 + $1,359.31 = $3,634.20

Therefore, your Ontario income tax payable for a taxable income of $60,000 is $3,634.20.
