Calculating your Ontario tax rate helps you understand how much tax you owe on your income. This calculator provides a quick way to estimate your provincial tax liability based on your income and deductions.

How Ontario Taxes Work

Ontario uses a progressive tax system, meaning your tax rate increases as your income rises. The province collects taxes through income tax, sales tax, and other levies. The main source of revenue is the Ontario Income Tax Act, which applies to most individuals and businesses.

Key Points

Ontario's tax system includes both federal and provincial components. The federal government handles income tax, while Ontario handles sales tax (HST) and other provincial taxes. The combined rate is what most people experience.

Types of Ontario Taxes

  • Income Tax: Applied to personal and corporate income
  • Sales Tax (HST): 13% on most goods and services
  • Property Tax: Based on assessed property value
  • Corporate Tax: 12.2% on corporate income

Use our calculator on the right to quickly estimate your tax rate based on your income and deductions.

Example Calculation

Let's calculate the tax for someone earning $50,000 with $5,000 in deductions:

  1. Taxable Income = $50,000 - $5,000 = $45,000
  2. Tax Rate = 5.05% (first bracket)
  3. Tax Owed = $45,000 × 5.05% = $2,272.50

This person would owe approximately $2,272.50 in Ontario income tax.
