Calculating your Ontario taxable income is essential for understanding your tax liability. This calculator helps you determine your taxable income by accounting for eligible deductions and credits available in Ontario.

How to Use This Calculator

To calculate your Ontario taxable income:

  1. Enter your total income for the year.
  2. Select your filing status (Single, Married, or Other).

Formula Used

The formula for calculating Ontario taxable income is:

Taxable Income = Total Income - Eligible Deductions

Where:

  • Total Income - Your gross income before any deductions.
  • Eligible Deductions - Amounts you can subtract from your income, such as RRSP contributions, medical expenses, and charitable donations.

Worked Example

Let's calculate the taxable income for a single individual with $60,000 in total income and $10,000 in eligible deductions.

Taxable Income = $60,000 - $10,000 = $50,000

In this example, the taxable income is $50,000.

Common Deductions in Ontario

Several deductions can reduce your Ontario taxable income:

  • RRSP Contributions - Contributions to a Registered Retirement Savings Plan.
  • Medical Expenses - Eligible medical expenses over 3% of your income.
  • Charitable Donations - Donations to registered charities.
  • Union Dues - Dues paid to a recognized trade union.
  • Home Office Deduction - Expenses for a home office if you work from home.
