How to Calculate Income Tax Return in Ontario

Calculating your Ontario income tax return involves several steps, including determining your taxable income, applying deductions and credits, and understanding the tax brackets. This guide will walk you through the process and provide a tax calculator to help you estimate your return.

Basic Tax Calculation

Your Ontario income tax is calculated based on your taxable income, which is your total income minus eligible deductions. The province uses a progressive tax system with different tax rates for different income brackets.

Taxable Income = Total Income - Deductions Ontario Tax = Taxable Income × Ontario Tax Rate

The current Ontario tax rates for 2023 are:

5.05% on the first $49,231 of taxable income
9.15% on the next $49,231 (from $49,231 to $98,462)
11.16% on the next $150,000 (from $98,462 to $248,462)
12.16% on the next $200,000 (from $248,462 to $448,462)
13.16% on taxable income over $448,462

For example, if your taxable income is $100,000, your Ontario tax would be calculated as:

$49,231 × 5.05% = $2,470.78 $49,231 × 9.15% = $4,515.38 $6,539 × 11.16% = $733.88 Total Ontario Tax = $2,470.78 + $4,515.38 + $733.88 = $7,720.04
