What Is a Tax Invoice (Australia)?

In Australia, a tax invoice is an invoice that meets the requirements of the GST Act and is used by GST-registered businesses. The buyer uses a valid tax invoice to claim a GST input tax credit on their next BAS.

An Australian tax invoice must include:

  • The words "Tax Invoice" clearly displayed
  • The seller's business name (or trading name)
  • The seller's ABN
  • The issue date
  • A description of items sold, including quantity and price
  • The GST amount, or a statement that the total includes GST
  • The total amount payable in AUD
  • For sales of $1,000 or more: the buyer's identity or ABN

GST registration is mandatory when your annual turnover hits $75,000 ($150,000 for non-profits). Tax invoices must be issued within 28 days of a customer's request for sales over $82.50 (GST inclusive). Without a valid tax invoice, the buyer can't claim a GST credit. Keep every tax invoice for at least five years to meet ATO record-keeping rules. InvoiceSonic's tax invoice template is ATO-compliant out of the box.
