2. Calculate Federal Tax:

Federal Tax = Taxable Income × Federal Tax Rate

3. Calculate Ontario Provincial Tax:

Provincial Tax = Taxable Income × Ontario Tax Rate

4. Calculate OHIP Premiums:

OHIP Premiums = Taxable Income × OHIP Rate

5. Calculate CPP Contributions:

CPP Contributions = Taxable Income × CPP Rate

6. Calculate Total Taxes and Deductions:

Total Taxes = Federal Tax + Provincial Tax + OHIP Premiums + CPP Contributions

7. Calculate After-Tax Income:

After-Tax Income = Gross Income - Total Taxes

Note: The tax rates and deductions used in this calculator are based on the 2018 tax year. For the most accurate results, ensure you enter your correct gross income and deductions.

Worked Example

Let's calculate the after-tax income for a single individual with a gross income of $50,000 and no additional deductions.

Given:

Gross Income: $50,000
Filing Status: Single
Deductions: $0

Calculations:

Taxable Income = $50,000 - $0 = $50,000
Federal Tax = $50,000 × 20.5% = $10,250
Ontario Tax = $50,000 × 20.5% = $10,250
OHIP Premiums = $50,000 × 1.66% = $830
CPP Contributions = $50,000 × 4.95% = $2,475
Total Taxes = $10,250 + $10,250 + $830 + $2,475 = $23,805
After-Tax Income = $50,000 - $23,805 = $26,195

Result: The after-tax income is $26,195.
