Tax Calculation Formula

The calculator uses the following simplified formula to estimate Ontario income tax:

Provincial Tax = Annual Income × Provincial Tax Rate Federal Tax = Annual Income × Federal Tax Rate CPP = Annual Income × CPP Rate EI = Annual Income × EI Rate

Where the tax rates are based on the current Ontario tax brackets for 2023:

Provincial Tax Rate: 5.05% (Ontario)
Federal Tax Rate: 15% (Canada)
CPP Rate: 5.95% (5.1% employee + 0.85% employer)
EI Rate: 1.66% (employee only)

Note: This calculator uses simplified rates. For exact tax calculations, consult the Canada Revenue Agency (CRA) or a tax professional.

Worked Example

Let's calculate the estimated tax for a single person with $50,000 annual income:

Provincial Tax = $50,000 × 5.05% = $2,525 Federal Tax = $50,000 × 15% = $7,500 CPP = $50,000 × 5.95% = $2,975 EI = $50,000 × 1.66% = $830

Total estimated tax deductions: $2,525 (provincial) + $7,500 (federal) + $2,975 (CPP) + $830 (EI) = $13,830

Your estimated take-home pay would be: $50,000 - $13,830 = $36,170
