Calculating Your Tax

The calculator uses the following formula to determine your Ontario income tax:

Tax Calculation Formula

For each tax bracket, calculate the tax as:

Tax = (Upper Bracket Limit - Lower Bracket Limit) × Tax Rate

Sum the taxes from all applicable brackets to get the total tax liability.

For example, if you earn $50,000 as a single filer:

$44,701 × 5.05% = $2,253.50
($50,000 - $44,701) × 9.15% = $526.49
Total tax = $2,253.50 + $526.49 = $2,779.99

This calculator does not account for deductions, credits, or other tax adjustments. For an accurate return, consult the CRA or a tax professional.

Worked Example

Let's calculate the tax for a married couple with $180,000 in taxable income:

Bracket	Taxable Income	Tax Rate	Tax Amount
$0 - $89,404	$89,404	5.05%	$4,522.22
$89,405 - $178,807	$89,403	9.15%	$8,136.76
$178,808 - $180,000	$1,193	11.16%	$132.54
Total Tax			$12,791.52

This married couple would owe approximately $12,791.52 in Ontario provincial taxes for 2020.
