How Ontario Taxes Are Calculated

Ontario uses a progressive tax system where higher incomes are taxed at higher rates. The tax is calculated by applying each tax rate to the portion of income that falls within that bracket.

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

The taxable income is calculated after deductions such as RRSP contributions, medical expenses, and other eligible deductions. The CRA provides detailed tax tables for each filing status.

Ontario Tax Brackets

For the 2023 tax year, Ontario's tax brackets are as follows:

Taxable Income	Tax Rate
$0 - $48,535	5.05%
$48,535.01 - $97,069	9.15%
$97,069.01 - $150,473	11.16%
$150,473.01 - $220,000	12.16%

Note: These rates are subject to change each year. Always verify with the latest CRA tax tables.

Worked Example

Let's calculate the Ontario tax for a single taxpayer with $60,000 taxable income:

$48,535 × 5.05% = $2,444.94
($60,000 - $48,535) × 9.15% = $1,055.06
Total tax = $2,444.94 + $1,055.06 = $3,500.00

Effective tax rate = ($3,500 / $60,000) × 100 = 5.83%
