Tax Invoice Requirements in Australia

For a taxable sale under $1,000, the ATO requires seven details on a tax invoice. Sales of $1,000 or more need one extra field — the buyer’s identity or ABN. Here is the full checklist, the GST wording rules, and an annotated example you can copy.

The 7 fields the ATO requires (sales under $1,000)

  1. That the document is a tax invoice. The words “Tax invoice” shown prominently, usually as the heading.
  2. The seller’s identity. Your business or trading name.
  3. The seller’s ABN. Your 11-digit Australian Business Number.
  4. The date the invoice was issued. The issue date, not the date of the work.
  5. A brief description of what was sold. Each item, including the quantity (where relevant) and the price.
  6. The GST amount (if any). Shown separately, or as “Total price includes GST” when GST is exactly 1/11 of the total.
  7. The extent of GST on each sale. Which sales on the invoice are taxable — needed when some items are GST-free.

The extra rule for sales of $1,000 or more

Once a taxable sale reaches $1,000 (GST-inclusive), the tax invoice must also show the buyer’s identity or ABN — their business name or their 11-digit ABN. Below $1,000 the buyer’s details are optional, though many businesses include them for their own records.

How to show GST correctly

  • GST is 1/11 of a GST-inclusive price. A $1,100 taxable sale contains $100 of GST.
  • You can keep prices GST-inclusive. If GST is exactly 1/11 of the total, add the line “Total price includes GST” instead of a separate GST column.
  • Mixed invoices must be clear. If you sell both taxable and GST-free items on one invoice, show which sales include GST.

Annotated tax invoice example

Here is a compliant tax invoice for a sale under $1,000, with each required field marked.

Tax invoice ← field 1: marked as a tax invoice
Window to Fit Pty Ltd ← field 2: seller identity
ABN 32 123 456 789 ← field 3: seller ABN
Invoice date: 14 June 2026 ← field 4: date issued
Supply and fit window frames × 1 ← field 5: description, quantity, price$750.00
GST ← field 6: GST amount$75.00
All items above are taxable sales ← field 7: extent of GST
Total (includes GST)$825.00

Because this sale is under $1,000, the buyer’s details are optional. If the total were $1,000 or more, you would add the buyer’s name or ABN.

Common mistakes that make an invoice non-compliant

  • The word “Tax invoice” is missing — a plain “Invoice” heading does not meet the requirement.
  • GST is charged even though the business is not registered for GST.
  • No ABN shown — the buyer may have to withhold 47% from the payment.
  • Line items too vague for the buyer to reconcile the GST.
  • Buyer details left off a sale of $1,000 or more.

Frequently asked questions

What are the tax invoice requirements in Australia?
For a taxable sale under $1,000, the ATO requires seven details: that the document is intended to be a tax invoice, the seller’s identity, the seller’s ABN, the date issued, a brief description of the items sold including quantity and price, the GST amount payable (or a statement that the total includes GST), and the extent to which each sale is taxable. Sales of $1,000 or more must also show the buyer’s identity or ABN.
Does a tax invoice need to show the GST separately?
Not always. If GST is exactly one-eleventh of the total price, you can show each line as GST-inclusive and add the statement “Total price includes GST” instead of a separate GST column. If a sale mixes taxable and GST-free items, the invoice must clearly show which sales include GST.
When does a tax invoice need the buyer’s details?
Once the taxable sale is $1,000 or more (GST-inclusive), the tax invoice must also show the buyer’s identity or ABN. Below $1,000 the buyer’s details are optional, though many businesses include them anyway.
What is the difference between an invoice and a tax invoice?
A plain invoice is a request for payment. A tax invoice is a document that meets the ATO’s GST requirements and lets a GST-registered buyer claim a GST credit. Only businesses registered for GST issue tax invoices; if you are not registered for GST, you issue a regular invoice with no GST.
When must a supplier provide a tax invoice?
If a customer asks for a tax invoice for a taxable sale, the supplier must provide one within 28 days of the request. A buyer needs a valid tax invoice to claim a GST credit on purchases of more than $82.50 (GST-inclusive).
