Tax Calculation Formula

The Ontario Tax Estimator uses the following formula to calculate your estimated taxes:

Federal Tax = Annual Income × Federal Tax Rate

Provincial Tax = Annual Income × Ontario Tax Rate

CPP = Annual Income × CPP Rate (5.95%)

EI = Annual Income × EI Rate (1.66%)

Total Tax = Federal Tax + Provincial Tax + CPP + EI

Net Income = Annual Income - Total Tax

The tax rates used are based on Ontario's 2023 tax brackets. For more precise calculations, you should use the official Canada Revenue Agency tax tables.

Worked Example

Let's calculate the taxes for a single individual with an annual income of $50,000.

Tax Type	Rate	Calculation	Amount
Federal Tax	20.5%	$50,000 × 20.5%	$10,250
Ontario Tax	20.5%	$50,000 × 20.5%	$10,250
CPP	5.95%	$50,000 × 5.95%	$2,975
EI	1.66%	$50,000 × 1.66%	$830
Total Tax			$24,305
Net Income		$50,000 - $24,305	$25,695

This example shows that a single individual with an annual income of $50,000 would owe approximately $24,305 in taxes, leaving them with a net income of $25,695.
