What a tax invoice must show

From the ATO’s tax invoices page (last updated 18 September 2026), a tax invoice for a taxable sale under A$1,000 needs enough information to clearly work out:

  1. that the document is intended to be a tax invoice
  2. the seller’s identity
  3. the seller’s ABN
  4. the date it was issued
  5. a brief description of the items sold, including the quantity (if applicable) and the price
  6. the GST amount (if any), shown separately or, if it’s exactly one-eleventh of the total, as “Total price includes GST”
  7. the extent to which each sale on the invoice is a taxable sale

For sales of A$1,000 or more it must also show the buyer’s identity or ABN. If a customer asks for a tax invoice you must give one within 28 days, unless the sale is A$82.50 (including GST) or less. The generator’s check list follows these points and tells you what’s still missing before you download.

If you’re not registered for GST

Only GST-registered businesses can issue a tax invoice or charge GST. business.gov.au’s how to invoice guide says a regular invoice should say “invoice”, must not say “tax invoice”, and commonly shows your business name, ABN, an invoice number, the date, your contact details, what you sold with quantity and price, when and how to pay, and the buyer’s name. That’s what the “No” option makes.

Getting invoices rather than sending them?

Check a supplier’s invoice against the same rules with the tax invoice checker, or see whether they were registered for GST on the invoice date with the GST check. Bookkeepers can check a whole supplier list from a Xero, MYOB or QuickBooks export; the first 25 are free.

Common questions

What must a tax invoice include in Australia?

The ATO lists seven details for taxable sales under A$1,000: that the document is intended to be a tax invoice, the seller's identity, the seller's ABN, the date it was issued, a brief description of what was sold (with quantity, if applicable, and price), the GST amount payable (shown separately, or as 'Total price includes GST' when the GST is exactly one-eleventh of the total), and the extent to which each sale on the invoice is taxable. From A$1,000 the invoice must also show the buyer's identity or ABN.

I'm not registered for GST. What kind of invoice do I send?

A regular invoice that doesn't show any GST. business.gov.au says it should use the word 'invoice' and that you must not use 'tax invoice'. Choose 'No' to the GST question and the generator makes a regular invoice with no GST lines.

Why does it check my ABN?

Customers often look a supplier up before paying, and a business customer may have to withhold tax from a payment if no ABN is quoted. The check shows whether your ABN is active, the names the register lists for it and whether it's registered for GST, so the invoice matches what they'll see. A typo is caught straight away by the ABN checksum.

How is the GST worked out?

It uses the ATO's total invoice rule: the taxable amounts are added up, then GST is worked out once (10% of a price before GST, or one-eleventh of a GST-inclusive price) and rounded to the nearest cent, with half a cent rounding up. Items you mark GST-free have no GST added.

Is my information stored?

No. The PDF is made when you click and isn't kept; ClearABN only counts that an invoice was made. If you tick 'Remember my business and payment details', they're saved in your own browser so the next invoice is quicker, and the invoice number moves on by one.

Can I email the PDF to my customer?

Yes. The ATO says a tax invoice doesn't need to be on paper; a PDF sent by email is fine as long as it has all the required details.
