Formula Used

The calculator uses the following formula to estimate your Ontario tax liability:

Tax Liability = (Taxable Income - Deductions) × Tax Rate + Credits

The tax rate is determined based on your filing status and taxable income. Ontario uses progressive tax brackets, meaning higher incomes are taxed at higher rates.

Worked Example

Let's calculate the tax liability for a single filer with $50,000 taxable income, $5,000 in deductions, and $1,000 in credits.

  1. Taxable Income = $50,000
  2. Deductions = $5,000
  3. Taxable Income After Deductions = $50,000 - $5,000 = $45,000
  4. Tax Rate for $45,000 (Single filer) = 20.05%
  5. Tax Before Credits = $45,000 × 20.05% = $9,022.50
  6. Credits = $1,000
  7. Estimated Tax Liability = $9,022.50 - $1,000 = $8,022.50

This example shows an estimated tax liability of $8,022.50. The actual amount may vary based on your specific circumstances.
