Tax invoice requirements in Australia

Last reviewed 2026-11-03 · Guidance, not tax or legal advice

Short answer: An Australian tax invoice must show: that it is a tax invoice, the seller's identity and ABN, the issue date, a brief description of the items (with quantity and price), the GST amount or a statement that the total includes GST, and how much of each sale is taxable. For sales of $1,000 or more it must also show the buyer's identity or ABN. You must provide one within 28 days if asked, for taxable sales over $82.50 including GST.

Timing rules

  • You only have to provide a tax invoice when the customer asks, for taxable sales over $82.50 including GST.
  • Once asked, you have 28 days to provide it.

The tax invoice generator prints “Tax invoice”, checks your ABN checksum and warns you about the $1,000 rule.

Frequently asked questions

Do I need to issue a tax invoice for small sales?

Not for taxable sales of $82.50 or less (including GST). A receipt or docket is enough, unless your customer asks for a tax invoice.

Can I issue a tax invoice if I'm not registered for GST?

No. Only GST-registered businesses can issue tax invoices. If you are not registered, issue a regular invoice without GST.

What if I leave my ABN off the invoice?

The payer may have to withhold 47% of the payment and send it to the ATO.
