How Tax Is Calculated

The income tax calculation in Ontario involves several steps:

Calculate federal taxable income by subtracting federal deductions from total income.
Calculate provincial taxable income by subtracting provincial deductions from total income.
Apply federal tax rates to the federal taxable income.
Apply provincial tax rates to the provincial taxable income.
Add the federal and provincial taxes to get the total tax liability.

Formula

Total Tax = Federal Tax + Provincial Tax

Federal Tax = Federal Taxable Income × Federal Tax Rate

Provincial Tax = Provincial Taxable Income × Provincial Tax Rate

Common deductions include RRSP contributions, medical expenses, and tuition fees. Credits can reduce your tax liability, such as the Ontario Child Benefit and the Canada Child Benefit.

Example Calculation

Let's calculate the income tax for an Ontario resident with a total income of $80,000, no deductions, and no credits.

Federal taxable income: $80,000
Provincial taxable income: $80,000
Federal tax: $80,000 × 20.5% = $16,400
Provincial tax: $80,000 × 9.15% = $7,320
Total tax: $16,400 + $7,320 = $23,720

This example shows the total tax liability without considering deductions or credits. In reality, your tax liability will be lower if you claim eligible deductions and credits.
