Formula Used

The calculator uses the following formulas to estimate your Ontario taxes:

Income Tax Calculation

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

Income Tax = (Gross Income - Basic Personal Amount) × Tax Rate

The Basic Personal Amount is $12,069 for single filers and $24,138 for couples in 2023.

CPP Calculation

Canada Pension Plan contributions are calculated as:

CPP = Gross Income × 0.0525 (employee portion)

EI Calculation

Employment Insurance premiums are calculated as:

EI = Gross Income × 0.0166 (employee portion)

Net Pay Calculation

Net pay is calculated as:

Net Pay = Gross Income - Income Tax - CPP - EI

Note: These are estimates based on current tax rates. Actual taxes may vary based on your specific situation and changes in tax laws.

Worked Example

Let's calculate the taxes for a single filer with a gross monthly income of $4,000.

Step 1: Calculate Income Tax

Gross annual income: $4,000 × 12 = $48,000

Basic Personal Amount: $12,069

Taxable income: $48,000 - $12,069 = $35,931

Income tax: $35,931 × 0.205 (Ontario tax rate for $35,931) = $7,364.705

Monthly income tax: $7,364.705 ÷ 12 ≈ $613.73

Step 2: Calculate CPP

CPP: $4,000 × 0.0525 = $210

Step 3: Calculate EI

EI: $4,000 × 0.0166 = $66.40

Step 4: Calculate Net Pay

Net pay: $4,000 - $613.73 - $210 - $66.40 ≈ $3,110.87

This example shows that a single filer with $4,000 monthly income would have approximately $613.73 in income tax, $210 in CPP, $66.40 in EI, and a net pay of about $3,110.87 per month.
