Formula Used

The calculator uses the following steps to determine your tax liability:

Tax Calculation Steps

  2. Apply Ontario tax brackets to taxable income
  3. Calculate CPP contributions (5.95% of earnings up to the maximum contribution base)

The Ontario tax brackets for 2023 are as follows:

Tax Bracket Tax Rate
$0 - $48,535 5.05%
$48,535.01 - $97,069 9.15%
$97,069.01 - $150,473 11.16%
$150,473.01 - $220,000 12.16%
Over $220,000 13.16%

Worked Example

Let's calculate taxes for a single person with $60,000 annual income:

  1. Taxable income: $60,000 (no deductions in this example)
  2. Ontario tax:
    • $48,535 × 5.05% = $2,453.84
    • ($60,000 - $48,535) × 9.15% = $1,046.16
    • Total Ontario tax = $2,453.84 + $1,046.16 = $3,500.00
  3. CPP: $60,000 × 5.95% = $3,570.00
  4. EI: $60,000 × 1.66% = $996.00
  5. Total deductions: $3,500 + $3,570 + $996 = $8,066
  6. Net pay: $60,000 - $8,066 = $51,934

Example Results

For $60,000 income, this person would pay approximately $3,500 in Ontario tax, $3,570 in CPP, and $996 in EI, leaving them with about $51,934 in net pay.
