How to write a tax invoice in Australia

If you are registered for GST, a customer who is claiming GST credits needs a proper tax invoice. Here is what it has to show.

Last updated: November 2026

When do you need to give one?

If you are registered for GST and a taxable sale is more than $82.50 (GST included), you must give a tax invoice when the customer asks for one. You have 28 days to provide it after a request. It is good practice to issue one every time.

Sales under $1,000

The tax invoice should show:

• the words Tax invoice
• your business name
• your ABN
• the date it was issued
• a short description of what was sold, with quantity and price
• the GST amount (or a note that the total includes GST)

Sales of $1,000 or more

All of the above, plus the buyer's name or ABN.

Example

Tax invoice INV-0042

Date: 12 November 2026
Bathroom floor tiling, 18 m2 at $85 = $1,530.00
GST: $153.00 · Total: $1,683.00
Client: Smith Builders Pty Ltd, ABN 98 765 432 109
