Tax invoices are usually issued to you by a supplier. However, in special cases, you, as the purchaser or recipient of the goods or services, may issue yourself a tax invoice. This is known in Australia as a recipient created tax invoice (RCTI), or in New Zealand a Buyer Created Tax Invoice.
When you print a bill recorded in AccountRight, by default Recipient Created Tax Invoice will be displayed.
See the AccountEdge help for details on printing purchases (Australia | New Zealand).
There are rules and regulations governing the use of recipient created tax invoices. For all the details, speak to your accounting advisor or visit the ATO website or IRD website.
