Ontario Tax Brackets for 2023

Ontario's progressive tax system applies different rates to different portions of your income. Here are the 2023 tax brackets:

Taxable Income	Tax Rate
$0 - $49,020	5.05%
$49,020.01 - $98,040	9.15%
$98,040.01 - $150,000	11.16%
$150,000.01 - $220,000	12.16%
$220,000.01 and above	13.16%

For example, if your taxable income is $100,000, the calculation would be:

$49,020 × 5.05% = $2,451.10
($100,000 - $49,020) × 9.15% = $4,860.35
Total tax = $2,451.10 + $4,860.35 = $7,311.45

($120,000 - $98,040) × 11.16% = $2,573.24
Total tax = $2,451.10 + $4,419.85 + $2,573.24 = $9,444.19
