How Ontario Income Tax Works

Ontario's income tax system is based on a progressive tax structure, meaning higher-income individuals pay higher tax rates. The tax is calculated by applying the appropriate tax rate to each portion of your taxable income that falls within a specific bracket.

Ontario Income Tax Calculation Formula

Tax = (Income in Bracket 1 × Rate 1) + (Income in Bracket 2 × Rate 2) + ... + (Income in Bracket N × Rate N)

For example, if you earn $100,000 as a single filer in Ontario:

$49,057 at 5.05% = $2,458.34
$49,060 at 9.15% = $4,475.85
Total tax = $2,458.34 + $4,475.85 = $6,934.19

This progressive system ensures that higher-income individuals contribute a larger share of their income to the provincial treasury.

Deductions and Tax Credits

Ontario offers various deductions and tax credits that can reduce your taxable income or lower your tax bill. Common deductions include:

RRSP contributions
Medical expenses
Donations to registered charities
Home office expenses
Education expenses

Tax credits, on the other hand, directly reduce the amount of tax you owe. Examples include:

Ontario Child Benefit
Ontario Trillium Benefit
Canada Child Benefit
Canada Workers Benefit

Important Note

Deductions and credits are not included in this calculator. For an accurate tax calculation, consult with a tax professional or use official government tax forms.
