How to Do a Tax Invoice

A tax invoice is the GST-compliant version of a regular invoice. To do one correctly in Australia, you need to clearly label it, include your ABN, show the GST amount, and meet all ATO requirements. Only businesses registered for GST can issue tax invoices.

To do a tax invoice the right way: 1. Open a tax invoice template or use a generator like InvoiceSonic 2. Add the words "Tax Invoice" prominently at the top 3. Include your business name and ABN 4. Add a unique invoice number and the issue date 5. List the client's name (and ABN if the sale is $1,000 or more) 6. Itemise each product or service with quantity, GST-exclusive price, and line total 7. Show the GST amount separately, or state "Total price includes GST" 8. Display the total amount payable 9. Add payment terms, due date, and your bank details

Save the tax invoice as a PDF, send to the client, and keep a copy for at least five years. For sales under $82.50 (GST inclusive), a tax invoice isn't strictly required — but issuing one is good practice.
