Tax Calculator Self Employed Ontario

Reviewed by Calculator Editorial Team

Calculating your Ontario self-employed taxes can be complex, but our tax calculator simplifies the process. Whether you're tracking your income, deductions, or net earnings, this tool provides accurate estimates based on current Ontario tax laws.

How the Tax Calculator Works

Our Ontario self-employed tax calculator estimates your income tax, Canada Pension Plan (CPP) contributions, Employment Insurance (EI) premiums, and net income. The calculation follows these steps:

  1. Calculate your total income from self-employment.
  2. Determine your applicable tax rate based on your income level.
  3. Calculate CPP contributions (5.95% of your income).
  4. Calculate EI premiums (1.66% of your income).
  5. Compute your net income by subtracting taxes, CPP, and EI from your total income.

The calculator uses the current Ontario tax rates and assumes you're not eligible for any additional deductions or credits beyond what's entered.

Formula Used

Income Tax: Ontario uses a progressive tax system with different rates for different income brackets. The formula is:

Income Tax = (Income × Tax Rate) - (Tax Credits + Deductions)

CPP Contributions: 5.95% of your income.

EI Premiums: 1.66% of your income.

Net Income: Income - (Income Tax + CPP + EI)

For the most accurate results, use the actual tax rates and brackets from the Canada Revenue Agency (CRA) for your specific situation.

Worked Example

Let's calculate taxes for a self-employed individual in Ontario with $75,000 in income.

  1. Income Tax: $75,000 falls into the highest tax bracket (53% for amounts over $48,535).
  2. Taxable Income = $75,000 - Basic Personal Amount ($12,069) = $62,931
  3. Income Tax = ($62,931 × 53%) - (Federal Tax Credits + Provincial Tax Credits) ≈ $22,000
  4. CPP: $75,000 × 5.95% = $4,462.50
  5. EI: $75,000 × 1.66% = $1,245.00
  6. Net Income: $75,000 - ($22,000 + $4,462.50 + $1,245.00) ≈ $47,302.50

This example shows that after taxes, CPP, and EI, the net income is approximately $47,302.50.
