Ontario Tax Brackets

Ontario uses a progressive tax system with the following tax brackets for the 2023 tax year:

Income Range	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+	13.16%

For example, someone earning $100,000 would pay:

$49,020 × 5.05% = $2,499.99
($100,000 - $49,020) × 9.15% = $4,802.95
Total tax = $2,499.99 + $4,802.95 = $7,302.94
