How Reverse GST Works in Ontario

Under the Reverse Charge Mechanism, the supplier is responsible for accounting for and remitting the GST on certain transactions. This means the customer pays the supplier the total amount including GST, and the supplier then accounts for the GST separately.

To determine the original price before GST was applied, you need to subtract the GST from the total amount. The formula for calculating the original amount before GST is:

Original Amount = Amount with GST / (1 + GST Rate)

For example, if you have a total amount of $100 including 13% GST, the original amount before GST would be $100 / 1.13 = $88.42.

This mechanism applies to specific types of goods and services, such as certain construction services, financial services, and telecommunications services.

Worked Examples

Let's look at two examples to illustrate how the Reverse GST Calculator works in Ontario.

Example 1: 5% GST Rate

Suppose you have a total amount of $200 including 5% GST. To find the original amount before GST:

  1. Divide the total amount by 1.05 (1 + 5%): $200 / 1.05 = $190.48
  2. The GST amount is $200 - $190.48 = $9.52

So, the original amount before GST is $190.48.

Example 2: 13% GST Rate

If you have a total amount of $500 including 13% GST, the calculation would be:

  1. Divide the total amount by 1.13 (1 + 13%): $500 / 1.13 ≈ $442.58
  2. The GST amount is $500 - $442.58 ≈ $57.42

Therefore, the original amount before GST is approximately $442.58.

Remember that the GST rate can vary depending on the type of goods or services. Always check the applicable rate for your specific situation.
