Formula Used

The Ontario tax return is calculated using the following formula:

Taxable Income = Total Income - Deductions

Tax Owed = Taxable Income × Tax Rate - Credits

The tax rate is determined by your filing status and taxable income brackets.

For 2024, Ontario uses a progressive tax system with rates ranging from 5.05% to 13.16% depending on income level.

Worked Example

Let's calculate a tax return for a single filer with $50,000 in taxable income and no additional deductions or credits.

  1. Taxable Income = $50,000
  2. Tax Rate = 5.05% (first $45,142)
  3. Tax Owed = $50,000 × 5.05% = $2,525

This example shows a basic calculation. Actual returns may vary based on deductions and credits.

Ontario offers several deductions that can reduce your taxable income:

  • Canada Pension Plan (CPP) contributions
