How to Calculate Hst Return Ontario

Reviewed by Calculator Editorial Team

Calculating your HST return in Ontario involves understanding how much Harmonized Sales Tax (HST) you've paid and how much you're entitled to receive back. This guide will walk you through the process, including the formula, assumptions, and practical steps to maximize your refund.

What is HST in Ontario?

Harmonized Sales Tax (HST) is a combined sales tax and Goods and Services Tax (GST) that applies to most goods and services in Ontario. When you file your tax return, you may be eligible for a refund of the HST you've paid but haven't claimed.

The Ontario government collects HST on behalf of the federal government and remits it to Ottawa. Businesses and individuals can claim a refund of the HST they've paid but haven't been credited on their tax return.

How to Calculate Your HST Return

To calculate your HST return, you'll need to determine how much HST you've paid during the year and how much you're entitled to receive back. Here's a step-by-step process:

  1. Gather all your receipts and invoices for the year.
  2. Calculate the total HST paid on eligible expenses.
  3. Subtract any HST you've already claimed on your tax return.
  4. Apply the Ontario HST refund rate to determine your refund amount.

The Ontario government typically refunds 90% of the HST you're entitled to, with the remaining 10% going to the federal government.

The HST Return Formula

The formula for calculating your HST return is straightforward:

HST Return = (Total HST Paid - HST Claimed) × Refund Rate

Where:

  • Total HST Paid - The total amount of HST you've paid during the year
  • HST Claimed - The amount of HST you've already claimed on your tax return
  • Refund Rate - The percentage of HST you're entitled to receive back (typically 90%)

This formula helps you determine the exact amount of HST you can expect to receive back as a refund.

Worked Example

Let's walk through an example to illustrate how the HST return calculation works.

Example Scenario

Total HST Paid: $5,000

HST Claimed: $3,000

Refund Rate: 90%

Calculation: ($5,000 - $3,000) × 0.90 = $1,800

In this example, you would be entitled to an HST refund of $1,800.

This example demonstrates how the formula can be applied to a real-world situation to determine your HST refund.
