Tax Calculation Formula

Federal Tax = Sum of (Taxable Income × Tax Rate for each bracket)

Ontario Tax = Sum of (Taxable Income × Tax Rate for each bracket)

Total Tax = Federal Tax + Ontario Tax

Net Income = Taxable Income - Total Tax

The tax rates are based on the current Ontario tax brackets for 2023. The calculator uses progressive tax brackets where higher income amounts are taxed at higher rates.

Worked Example

Let's calculate the tax for a single filer with $50,000 taxable income:

Income Range	Federal Rate	Ontario Rate	Taxable Amount	Federal Tax	Ontario Tax
$0 - $12,069	15%	5.05%	$12,069	$1,810.35	$60.87
$12,069 - $47,630	20.5%	9.15%	$35,561	$7,330.21	$3,251.65
$47,630 - $50,000	26%	11.16%	$2,370	$616.20	$266.42
Total				$9,756.76	$3,624.94

Total tax paid: $13,381.70

Net income after taxes: $36,618.30

Common Deductions

Several deductions can reduce your taxable income and lower your tax bill. Common deductions include:

RRSP contributions
Charitable donations
Medical expenses
Home office expenses
Tuition and education expenses
Moving expenses
Capital losses

Important Note

Not all deductions apply to everyone. The Canada Revenue Agency has specific rules for each type of deduction. Always consult a tax professional to ensure you're claiming eligible deductions.

Tax Credits

Tax credits directly reduce the amount of tax you owe. Some common tax credits include:

Canada Child Benefit (CCB)
Canada Workers Benefit (CWB)

These credits can significantly reduce your tax liability, sometimes even resulting in a refund if the credits exceed your tax owed.
