Information from the Australian Taxation Office states that tax invoices must include at least seven pieces of information to be valid.

For sales of less than $1000, the seven details are:

  1. The words ‘Tax Invoice’ must be used – preferably at the top.
  2. Your identity as the seller, such as your business name or trading name. Contact details are optional, but recommended.
  3. Your ABN or ACN.
  4. The date you created the tax invoice.
  5. A brief list of the items sold or services performed, including quantity and price.
  6. The GST amount (if any) payable. You can display GST for each item in a separate column, or within the total price. If you choose not to display it separately, use a statement such as ‘Total includes GST’ as this is needed for the next detail.
  7. The extent to which each item sold includes GST. You’ll meet this requirement if you either:
    • show the GST amount for each item
    • clearly state that the total price includes GST.

Tax invoices for sales of $1000 or more also need to show the buyers identity or ABN.

Invoice or tax invoice?

If you run a business that is not registered for Goods & Services Tax (GST), your invoices won’t include a tax component. This is called a regular invoice.

If you’re registered for GST, your invoice must be a tax invoice. Tax invoices are different as they include the GST amount for each item along with some extra details. If you’re not registered for GST, your invoices should not include the words ‘tax invoice’ – you must issue normal invoices.

You need to provide a tax invoice if any of these apply to the sale:

  • the purchase is taxable
  • the purchase is more than $82.50 (including GST)
  • your customer asks for one.

If your customer requests a tax invoice and you’re not registered for GST, your invoice should show that no GST on the purchase. You can do this by including the statement ‘Price does not include GST’ or showing the GST component as nil or zero.
