How Ontario Taxes Are Calculated

Ontario uses a progressive tax system where your tax rate increases as your income rises. The provincial tax is calculated using the following formula:

Provincial Tax = Sum of (Taxable Income × Tax Rate for each Bracket)

The 2024 Ontario tax brackets and rates are as follows:

Taxable Income	Tax Rate
$0 - $45,142	5.05%
$45,142.01 - $90,287	9.15%
$90,287.01 - $150,000	11.16%
$150,000.01 - $220,000	12.16%
Over $220,000	13.16%

The calculator applies these rates progressively to your taxable income. For example, if your taxable income is $50,000:

$45,142 × 5.05% = $2,264.29
($50,000 - $45,142) × 9.15% = $421.59
Total Provincial Tax = $2,264.29 + $421.59 = $2,685.88

Worked Examples

Example 1: Single Filer with $50,000 Income

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

First $45,142: $45,142 × 5.05% = $2,264.29
Next $4,858: $4,858 × 9.15% = $442.19
Total Provincial Tax: $2,264.29 + $442.19 = $2,706.48
Effective Tax Rate: ($2,706.48 / $50,000) × 100 = 5.41%

Example 2: Married Filer with $100,000 Income

For a married filer with $100,000 taxable income:

First $45,142: $45,142 × 5.05% = $2,264.29
Next $45,145: $45,145 × 9.15% = $4,117.51
Next $9,713: $9,713 × 11.16% = $1,085.19
Total Provincial Tax: $2,264.29 + $4,117.51 + $1,085.19 = $7,466.99
Effective Tax Rate: ($7,466.99 / $100,000) × 100 = 7.47%
