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

The Ontario Basic Personal Amount (BPA) is $11,474 for single filers and $22,948 for married couples in 2017. Tax rates vary based on income brackets.

Worked Example

For a single filer with $50,000 taxable income in 2017:

Income Bracket	Tax Rate	Taxable Amount	Tax
$0 - $42,961	5.06%	$42,961	$2,193.27
$42,962 - $85,923	9.15%	$7,039	$638.96
$85,924 - $150,000	11.16%	$0	$0
$150,001 - $220,000	12.16%	$0	$0
Over $220,000	13.16%	$0	$0
Total Tax Before BPA			$2,832.23
Ontario Basic Personal Amount (BPA)			-$11,474.00
Ontario Provincial Tax			$2,832.23 - $11,474.00 = -$8,641.77

In this example, the filer receives a refund of $8,641.77 because their tax liability is less than the Ontario Basic Personal Amount.
