What belongs on a New Zealand tax invoice.

IRD expects certain fields on a tax invoice. This is a plain-language checklist — not tax advice.

• Your name and GST number if you are GST registered.
• Customer name and the job or site if it differs from the billing address.
• Date and an invoice number (sequential helps at year end).
• Description of goods or services — labour and materials as separate lines is fine.
• Amounts in NZD with GST shown or a statement that the total includes GST.
