Goods and services tax (GST)

GST is a 15% tax added to the price of most goods and services in New Zealand, including imported goods and services. Anyone registered for GST must file returns.

Filing GST through our gateway services

The GST application programming interface (API) lets businesses:

  • file returns in real time
  • amend returns
  • retrieve a return due date
  • query return status
  • retrieve previously filed returns.

When a GST return is filed, the difference between the amount of GST collected and paid needs to be worked out. Any software built will need to include this function.
