What a GST invoice must include in New Zealand

If you're GST-registered, your customers need a proper tax invoice to claim back the GST they've paid. A compliant GST invoice generally shows:

  • The words “tax invoice” in a prominent place
  • Your business name and GST number
  • The date the invoice is issued
  • A description of the goods or services you supplied
  • The quantity or amount
  • The amount excluding GST, the GST, and the total (or the total including GST with a note that it includes GST)
  • For supplies over $1,000, the buyer's name and address

The generator above lays all of this out for you automatically.

Do I have to charge GST?

Only if you're GST-registered. You must register once your turnover passes $60,000 in any 12-month period; below that it's optional. New Zealand GST is 15%, added on top of your ex-GST prices.
