Formula Used

Income Tax Calculation

Ontario income tax is calculated using progressive tax brackets. The formula is:

Income Tax = (Income × Federal Tax Rate) + (Income × Ontario Tax Rate)

Where Federal Tax Rate and Ontario Tax Rate are based on your income bracket.

CPP Contributions

CPP contributions are calculated as:

CPP = Income × CPP Rate

The current CPP rate is 5.95% for contributions and 4.45% for employer contributions.

EI Premiums

EI premiums are calculated as:

EI = Income × EI Rate

The current EI rate is 1.66% for contributions and 1.4% for employer contributions.

Net Income

Net income is calculated as:

Net Income = Income - Income Tax - CPP - EI

Worked Example

Let's calculate taxes for a self-employed individual with $80,000 in business income for 2023.

Example Calculation

Income: $80,000

Federal Tax Rate: 20.5% (for income between $53,359 and $106,717)

Ontario Tax Rate: 13.16% (for income between $48,535 and $97,069)

Income Tax: ($80,000 × 20.5%) + ($80,000 × 13.16%) = $16,400 + $10,528 = $26,928

CPP: $80,000 × 5.95% = $4,760

EI: $80,000 × 1.66% = $1,328

Net Income: $80,000 - $26,928 - $4,760 - $1,328 = $47,084

This example shows that for $80,000 in income, the estimated net income after taxes and deductions is $47,084.
