Ontario Tax Basics

Ontario has a progressive income tax system, meaning your tax rate increases as your income rises. The basic tax rates for 2024 are:

5.05% on the first $51,446 of taxable income
9.15% on the next $51,446
11.16% on the next $51,446
12.16% on the next $102,892
13.16% on amounts over $257,786

These rates apply to individuals. Different rates apply to corporations and other entities. The Ontario government also imposes the Ontario Health Tax (OHT) at 1.5% on taxable income over $100,000.

Example Calculation

Let's calculate the tax for a single individual with $60,000 in taxable income:

Tax = (51,446 × 0.0505) + (51,446 × 0.0915) + (60,000 - 102,892 × 0.1116) Tax = $2,600 + $4,690 + $5,710 = $13,000

This example shows the progressive tax calculation. The first $51,446 is taxed at 5.05%, the next $51,446 at 9.15%, and the remaining $6,108 at 11.16%. The total tax liability is $13,000.

Formula Used

The calculator uses the following formula to calculate Ontario tax:

if (income ≤ 51,446) { tax = income × 0.0505 } else if (income ≤ 102,892) { tax = 51,446 × 0.0505 + (income - 51,446) × 0.0915 } else if (income ≤ 154,338) { tax = 51,446 × 0.0505 + 51,446 × 0.0915 + (income - 102,892) × 0.1116 } else if (income ≤ 257,786) { tax = 51,446 × 0.0505 + 51,446 × 0.0915 + 51,446 × 0.1116 + (income - 154,338) × 0.1216 } else { tax = 51,446 × 0.0505 + 51,446 × 0.0915 + 51,446 × 0.1116 + 102,892 × 0.1216 + (income - 257,786) × 0.1316 }

This formula accounts for Ontario's progressive tax rates. The calculator also includes the Ontario Health Tax (OHT) for incomes over $100,000 at 1.5% of the amount over $100,000.
