Tax Calculation Formula

The calculator uses the following formulas for Ontario taxes:

Ontario Income Tax

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

Ontario Tax = Sum of (Taxable Income × Tax Rate for each bracket)

Where taxable income is your annual income minus basic personal amount ($12,343 for 2023).

Canada Pension Plan (CPP)

CPP contributions are calculated as:

CPP = Annual Income × CPP Rate (5.95% for 2023)

Maximum CPP contribution is $3,410 for 2023.

Employment Insurance (EI)

EI premiums are calculated as:

EI = Annual Income × EI Rate (1.66% for 2023)

Maximum EI premium is $870 for 2023.

Net Pay

Net pay is calculated as:

Net Pay = Annual Income - (Ontario Tax + CPP + EI)

Then divided by 52 to get weekly net pay.

Worked Example

Let's calculate taxes for an annual income of $50,000:

Tax Component	Calculation	Amount
Ontario Tax	($50,000 - $12,343) × 0.0505 = $18,833.58	$18,833.58
CPP	$50,000 × 0.0595 = $2,975.00	$2,975.00
EI	$50,000 × 0.0166 = $830.00	$830.00
Total Deductions	$18,833.58 + $2,975 + $830 = $22,638.58	$22,638.58
Net Pay (Annual)	$50,000 - $22,638.58 = $27,361.42	$27,361.42
Net Pay (Weekly)	$27,361.42 / 52 ≈ $526.18	$526.18

For this income, you would pay approximately $22,638.58 in taxes and deductions, leaving you with about $27,361.42 annually or $526.18 per week.
