Changes aimed at modernising GST rules for invoicing and record keeping are being introduced.

Some changes came into effect on 30 March 2022. The majority come into effect on 1 April 2023.

The new rules are designed to support e-invoicing and electronic record keeping, particularly New Zealand’s adoption of the Pan European Public Procurement Online (PEPPOL) framework.

There is no change to the GST calculation, only the rules relating to invoicing and record keeping.

Overview of changes

Starting on 1 April 2023, there will be new terminology to support flexible record keeping practices. For example, the term 'taxable supply information' will replace the current term 'tax invoice'.

In addition, starting on 1 April:

  • new information requirements will need to be met based on the value and type of the supply
  • transaction records, accounting systems, supplier agreements and contracts can be used to meet the information requirements
  • a single document that holds all the supply information will no longer need to be kept, such as a tax invoice, credit note or debit note
  • taxable supply information can be provided using an automated direct exchange between a buyer's and seller’s software, for example, PEPPOL e-invoicing.
