How Ontario Taxes Are Calculated

Ontario uses a progressive tax system where your tax rate increases as your income increases. The 2024 tax rates are as follows:

Taxable Income	Tax Rate
$0 - $45,142	5.05%
$45,142.01 - $90,281	9.15%
$90,281.01 - $150,000	11.16%
$150,000.01 - $220,000	12.16%
Over $220,000	13.16%

Tax Calculation Formula

The provincial tax is calculated using progressive brackets:

Calculate tax for each bracket: (Upper limit - Lower limit) × Rate
Sum all bracket taxes
Add tax for the final bracket: (Income - Upper limit) × Rate

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

$45,142 × 5.05% = $2,264.27
($90,281 - $45,142) × 9.15% = $4,177.56
($100,000 - $90,281) × 11.16% = $1,024.46
Total = $2,264.27 + $4,177.56 + $1,024.46 = $7,466.29

Worked Examples

Example 2: Married Filer with $120,000 Income

($90,281 - $45,142) × 9.15% = $4,177.56
($120,000 - $90,281) × 11.16% = $3,483.66
