Requirements of tax invoices
Tax invoices for taxable sales of less than $1,000 must include enough information to clearly determine the following seven details:
that the document is intended to be a tax invoice
the seller's identity
the seller's Australian business number (ABN)
the date the invoice was issued
a brief description of the items sold, including the quantity (if applicable) and the price
the GST amount (if any) payable – this can be shown separately or, if the GST amount is exactly one-eleventh of the total price, as a statement such as 'Total price includes GST'
the extent to which each sale on the invoice is a taxable sale (that is, the extent to which each sale includes GST)
Example 1, below, meets this requirement because the sale is clearly identified as being fully taxable by the words 'total price including GST'
Example 2 meets this requirement in two ways: it shows the GST included in each line item (see column with the GST amount), and the sale is clearly identified as being fully taxable by the words 'the total price includes GST'.
In addition, tax invoices for sales of $1,000 or more need to show:
the buyer's identity or ABN
If your tax invoices meet the requirements for sales of $1,000 or more, you can also use them for sales of lesser amounts.
Example 1: Tax invoice for a sale under $1,000
