Tax invoice vs invoice: what's the difference in Australia?

Understand the difference between a regular invoice and a tax invoice in Australia, especially for GST-registered small businesses.

In Australia, a regular invoice and a tax invoice are not the same thing. The difference matters most when your business is registered for GST, because a tax invoice shows GST details and supports the buyer's GST credit record.

The short version

A regular invoice asks a customer to pay. A tax invoice also includes the GST information required when a GST-registered business makes a taxable sale. business.gov.au states that GST-registered businesses must use tax invoices, while businesses that are not registered for GST use regular invoices that do not show tax.

When should you use each one?

Why the label matters

Using the wrong label can confuse customers and create messy records. If you are not registered for GST, avoid showing GST amounts or calling the document a tax invoice. If you are GST-registered, make sure the invoice includes the required GST details and the right business information.
