What GST means on an invoice

GST is a 10% tax added to many goods and services in Australia. If your business is registered for GST, your invoice generally needs to show the GST amount clearly enough for the client and your records.

What a tax invoice usually includes

A practical tax invoice should make the basics obvious: who issued it, who it is for, what was supplied, the date, the invoice number, the total, and the GST amount.

The words "Tax Invoice" where required.
Your business name and ABN.
A unique invoice number and issue date.
A clear description of the work or services.
The GST amount or a clear GST-inclusive total.

Example: If Northstar Studio charges $5,400 before GST, the GST line is $540 and the invoice total is $5,940.

If you are not registered for GST

Do not add GST just because other invoices have it. If you are below the registration threshold or not registered, your invoice should avoid implying that GST has been charged.
