Australia invoicing rules
- A GST-registered seller must give a tax invoice within 28 days when a buyer asks for one, for any taxable sale over A$82.50 including GST.
- When the invoice total includes GST at exactly one-eleventh of the price, a statement such as "Total price includes GST" can replace a separate GST amount.
- An invoice that mixes taxable and GST-free items must show which items are taxable, for example by marking them with an asterisk and explaining the mark.
- A business that is not registered for GST must not title its document "Tax invoice" or charge GST, but should still show its ABN to avoid buyers withholding tax at the top rate.
- Keep tax invoices and other business records for five years.
E-invoicing, simplified invoices and record keeping
Peppol e-invoicing is available and Australian government agencies accept it, but there is no business-to-business mandate as of October 2026.
No tax invoice is needed for sales of A$82.50 or less including GST; a receipt or cash register docket is enough for the buyer.
Keep issued and received invoices for at least 5 years in Australia.
