How Ontario Income Taxes Work

Ontario's income tax system is based on a combination of federal and provincial taxes. Here's how it works:

Your total income is divided into taxable and non-taxable portions
Taxable income is calculated by subtracting deductions from your total income
Tax is calculated based on progressive brackets for both federal and provincial taxes
Credits and deductions may reduce your final tax liability

Tax Calculation Formula

Total Tax = Federal Tax + Provincial Tax

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

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

The calculator automatically applies these formulas to provide your estimated tax liability.

Deductions and Tax Credits

Several deductions and credits can reduce your taxable income or lower your tax bill:

Common Deductions

RRSP contributions
Medical expenses
Donations to registered charities
Home office expenses

Tax Credits
