What Needs to Be on an Invoice in Australia?

Australian invoices need to meet ATO record-keeping rules, and if you're GST registered they must be "tax invoices" with extra details. Issuing complete, accurate invoices is essential for BAS, tax returns, and avoiding the No-ABN Withholding rule.

A complete Australian invoice includes:

The word "Invoice" or "Tax Invoice" (if GST registered)
Your business name and ABN
Your contact details — address, phone, email
A unique sequential invoice number
The issue date
The client's name and billing address
Description of each item, quantity, unit price, and line total
Subtotal, GST (if registered), and total amount payable in AUD
Payment due date and payment methods (bank, BPAY, PayID)
For tax invoices over $1,000: the buyer's identity or ABN

Without an ABN, clients are required to withhold 47% of your payment under No-ABN Withholding. Keep every invoice — sent and received — for at least five years. InvoiceSonic includes every required field by default and is designed for Australian businesses.
