The e-invoicing journey started with the joint announcements of Australian and New Zealand government stakeholders of the adoption of the Peppol standard for the Trans-Tasman e-Invoicing framework in February 2019. New Zealand became a Peppol Authority and the Peppol network facilitates the exchange of digital accounting documents including e-Ordering, e-Catalogue, and e-Dispatch. Filing a tax return is mandatory and it must be submitted electronically before July 7 too. In New Zealand, businesses of all sizes can begin using e-Invoices. While small businesses are exempt from the requirement, large businesses and government organizations must begin receiving e-Invoices by March 31, 2022. Small businesses may use e-Invoices voluntarily if they have a Peppol-enabled accounting software and if their supplier agrees to receive the invoice in electronic format. All types of e-Invoices must contain the New Zealand Business Number (NZBN) which is a globally unique identifier. All companies can have NZBN even if you’re self-employed.
