Income Tax Brackets for Self-Employed Individuals

Ontario uses a progressive tax system with these brackets for 2023:

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%
Over $220,000	13.16%

Formula and Assumptions

The calculator uses the following formula to estimate your self-employment taxes:

Net Income = Gross Income - Deductions

Income Tax = Net Income × Ontario Tax Rate

CPP = Net Income × 5.1%

EI = Net Income × 1.66%

Total Taxes = Income Tax + CPP + EI

Net Income After Taxes = Net Income - Total Taxes

Assumptions

All calculations are based on 2023 tax rates
Deductions are estimated and may vary based on your specific situation
This calculator doesn't account for all possible deductions or credits

Worked Example

Let's calculate taxes for a self-employed individual with $75,000 gross income and $15,000 in deductions.

Example: Gross Income = $75,000, Deductions = $15,000

Step-by-Step Calculation

Net Income = $75,000 - $15,000 = $60,000
Income Tax Rate = 9.15% (since $60,000 falls in the $49,020.01 - $98,040 bracket)
Income Tax = $60,000 × 9.15% = $5,490
CPP = $60,000 × 5.1% = $3,060
EI = $60,000 × 1.66% = $996
Total Taxes = $5,490 + $3,060 + $996 = $9,546
Net Income After Taxes = $60,000 - $9,546 = $50,454

In this example, the individual would pay $9,546 in taxes and keep $50,454 as net income.
