COVID-19 - Level 2 If you have been affected by COVID-19, we may be able to help. Find out more

We use purchase orders to approve, manage and make payment for all purchases:

  • over $500 (plus GST)
  • made under a contract or agreement.

Purchase order numbers

You need an Inland Revenue purchase order number if you supply goods or services over the $500 (plus GST) threshold. You can get the number from the Inland Revenue contact who requested the goods or services.

We will return any invoices for a supply over $500 (plus GST) or for a supply made under a contract or agreement that don't have a valid purchase order number.

Tips to make sure your payment isn't delayed

  • Submit a complete and accurate invoice, ie, one that meets the requirements of the Goods & Services Tax Act 1985.
  • If your business is GST-registered, include your GST number and the words "Tax Invoice".
  • Include the name of your Inland Revenue contact who requested the goods and services as well as the purchase order number.
  • Make sure the purchase order matches the invoice exactly, including what was delivered, unit of measure, quantity and unit price.
  • Correct any discrepancies or changes before sending your invoice.
