GST-inclusive vs. GST-exclusive prices

Australia is a tax-inclusive country that applies a GST percentage to all taxable products and services. The current rate of GST in Australia is 10%.

The difference between GST-inclusive and GST-exclusive prices or GST-inclusive vs. GST-exclusive prices refers to whether or not the price stated includes GST.

GST-Inclusive Price

This is the final cost, which takes into account both the cost of the item or service and any applicable GST. When a price is marked as GST-inclusive, it denotes that the GST has already been added to the shown amount. 

Customers are accustomed to seeing prices in this format because it offers a clear sense of the entire amount they will pay at the moment of purchase.

For instance, if a shirt is priced at $50 with GST included, that amount is the total you’ll pay, and it already includes the base price of the garment as well as the 10% GST. The cost of the shirt itself is $45.45; the GST amount is around $4.55.

GST-Exclusive Price

On the other hand, GST-exclusive pricing is the cost of a good or service before the GST is included. 

This strategy is more frequently used in sectors with complex pricing methods or in business-to-business transactions. If a price is marked as GST-exclusive, the GST will be charged at the time of the purchase.

For instance, if a company quotes another company a price for a product of $100 that is GST-exclusive, the buyer would need to figure out the GST and add it to the price to get the final price. The GST in this situation would be $10, making the total amount due $110.

Invoices and Receipts:

Businesses in Australia are expected to submit accurate and clear invoices and receipts that individually list the GST amount, whether the price is GST-inclusive or GST-exclusive.

This will guarantee the transaction’s accountability and openness. 

The following information should appear on invoices and receipts:

  • The total amount due after GST(if GST is included).
  • The entire price due before GST (if GST-exclusive).
  • The amount of GST charged.

These procedures facilitate understanding of the breakdown of costs and taxes in the transaction for both businesses and customers.

How to calculate GST in Australia?

Here’s a little step-by-step guide on how to calculate GST in Australia. This will also give you an idea of GST-inclusive and GST-exclusive prices.

GST-inclusive vs. GST-exclusive prices

Step 1: Determine the GST-Excluded Price

Start with the item or service’s original cost before GST is deducted. This is the GST-exclusive pricing.

Step 2: Determine the GST Amount

Multiply the GST-exclusive pricing by Australia’s 10% GST rate to get the final price. The equation is:

GST Amount= GST-Exclusive Price x 0.10

For instance, if the price before GST is $100:

GST: $100 x 0.10 = $10.

Step 3: Add the GST Amount to the GST-Exclusive Price.

To get the total amount due, including GST, add the computed GST amount to the GST-exclusive price. The equation is:

Total Price (Including GST) = GST-Exclusive Price + GST Amount

Using the preceding example:

Total cost = $100 + $10 = $110.

GST included, the total amount due is thus $110 in total.

For GST-inclusive pricing, you may also compute the GST amount by dividing the GST-inclusive price by 11 (because 10% of the total is the GST cost).

You may obtain the GST-exclusive pricing by deducting this GST amount from the GST-inclusive price.

For instance, if the price is $110 with GST included:

GST Amount = GST-Inclusive Price ÷ 11 

 $110 / 11= $10

GST-Exclusive Price = GST-Inclusive Price – GST Amount

 $110 – $10 = $100.

This makes it simple to convert between GST-inclusive and GST-exclusive amounts.

It’s vital to note that businesses must explicitly indicate the GST component individually when presenting pricing on invoices, receipts, or other transaction papers, even if the prices are GST-inclusive. 

This transparency assists customers and other companies in understanding the amount of GST levied.
