Reviewed by Calculator Editorial Team

Calculating your Ontario tax refund helps you understand how much money you're entitled to receive from the government. This guide explains the process, provides a calculator, and offers practical advice for filing your return.

How to Calculate Your Ontario Tax Refund

The Ontario tax refund is the difference between the taxes you've paid during the year and what you owe based on your income. Here's how to calculate it:

  1. Determine your total taxable income for the year.
  2. Calculate your Ontario tax liability using the progressive tax rates.
  3. Subtract your total tax payments from your tax liability to find your refund amount.

Use our calculator below to perform these calculations quickly and accurately.

Tax Refund Formula

Tax Refund = Total Tax Paid - Ontario Tax Liability

Ontario Tax Liability = Taxable Income × Progressive Tax Rate

Note: This calculation provides an estimate. Your actual refund may vary based on deductions, credits, and other factors.

Tax Refund Formula

The tax refund formula is straightforward but involves several steps. Here's a detailed breakdown:

  1. Calculate Taxable Income: Subtract allowable deductions from your total income.
  2. Determine Ontario Tax Liability: Apply Ontario's progressive tax rates to your taxable income.
  3. Calculate Refund: Subtract your total tax payments from your tax liability.

The Ontario tax rates are progressive, meaning higher income brackets are taxed at higher rates. The current rates (as of 2023) are:

  • 0% on the first $44,703 of taxable income
  • 5.05% on the next $44,703 ($44,704 to $89,406)
  • 9.15% on the next $55,231 ($89,407 to $144,637)
  • 11.16% on the next $66,191 ($144,638 to $210,828)
  • 12.16% on the next $100,000 ($210,829 to $310,828)
  • 13.16% on amounts over $310,828

Worked Example

Let's calculate a tax refund for someone with $100,000 in taxable income and $8,000 in total tax payments.

  1. Taxable Income = $100,000
  2. Ontario Tax Liability:
    • $44,703 × 0% = $0
    • $44,703 × 5.05% = $2,261.66
    • $55,231 × 9.15% = $5,042.29
    • $5,263 × 11.16% = $590.66
    • Total = $2,261.66 + $5,042.29 + $590.66 = $8,144.61
  3. Tax Refund = $8,000 - $8,144.61 = -$144.61

In this example, the person owes an additional $144.61 in taxes rather than receiving a refund.
