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)
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.
