How Ontario Income Tax Works

Ontario uses a progressive tax system where your tax rate increases as your income grows. The province also has a flat tax rate for certain types of income like capital gains and dividends.

Key Formula

Ontario income tax = (Taxable income × Progressive tax rate) + (Capital gains × 50%) + (Dividends × 12.16%)

The Ontario government provides several tax credits and deductions that can reduce your taxable income. Common deductions include:

RRSP contributions
Medical expenses over 3% of income
Donations to registered charities
Home office expenses

Worked Example

Let's calculate the tax for a single person with $120,000 in taxable income, $10,000 in capital gains, and $5,000 in dividends.

Calculate progressive tax: $120,000 × 11.16% = $13,392
Calculate capital gains tax: $10,000 × 50% = $5,000
Calculate dividend tax: $5,000 × 12.16% = $608
Total tax = $13,392 + $5,000 + $608 = $18,900

This person would pay $18,900 in Ontario income tax for the year.
