Invoicing in New Zealand centers on the Goods and Services Tax (GST), a broad-based 15% tax on most goods and services. Businesses with annual taxable supplies exceeding NZ$60,000 must register for GST with Inland Revenue (IR) and issue tax invoices showing their IRD number, the GST amount, and whether prices are GST-inclusive or exclusive. Tax invoices are essential for buyers to claim GST input credits, and simplified tax invoices can be used for supplies under NZ$1,000.
New Zealand has a straightforward, transparent tax environment that is consistently ranked among the easiest in the world for business compliance. The IRD number serves as the primary business identifier, and invoicing requirements are clearly defined in the Goods and Services Tax Act 1985. Payment is typically in NZD via direct bank transfer, which is the dominant B2B payment method across the country. Bank account numbers are included directly on invoices, and most New Zealand businesses expect prompt, no-frills documentation.
Inland Revenue requires GST records to be kept for at least seven years from the end of the tax period they relate to. E-invoicing via the Peppol network is supported and actively promoted for government procurement, though it is not yet mandatory for all private sector businesses. The New Zealand government has invested in the Peppol framework to improve efficiency across supply chains, and adoption is growing among larger enterprises. New Zealand's relative simplicity compared to many other jurisdictions makes it an accessible market for invoicing, but businesses must still ensure all mandatory fields are present to maintain GST compliance and avoid issues during IR audits.
Invoice checklist: common fields in New Zealand
What buyers, auditors, and tax authorities often expect to see on a commercial invoice. “Required” reflects typical compliance expectations for registered businesses—not every sole trader scenario.
Seller Name & Address
Usually requiredRegistered name and address of the GST-registered supplier. The name must match the registration held with Inland Revenue to ensure buyers can verify the supplier's GST status.
Buyer Name & Address
Usually requiredRequired for tax invoices over NZ$1,000 including GST. For invoices under this threshold, buyer details are recommended for good practice but not strictly mandatory.
Invoice Number
Usually requiredA unique identifying number for each invoice, used for record-keeping and audit trail purposes. Sequential numbering is standard practice and expected by Inland Revenue during reviews.
Invoice Date
Usually requiredDate of issue, which determines the GST return period in which the transaction is reported. The supply date should also be noted if it differs from the invoice date.
IRD Number
Usually requiredInland Revenue Department number of the GST-registered supplier. This is the primary identifier used by buyers and IR to verify registration status and process input tax credit claims.
Tax Breakdown
Usually requiredThe GST amount must be shown separately, or the invoice must include a clear statement that the total price includes GST. The standard rate is 15% for all taxable supplies.
Currency
Usually requiredNZD for domestic invoices. Foreign currency invoices require conversion to NZD for GST reporting purposes using an exchange rate acceptable to Inland Revenue.
Payment Terms
Often optionalTypically the 20th of the month following invoice, or net 14 to 30 days. Clear payment terms reduce disputes and help both parties manage cash flow effectively.
Description of Goods or Services
Usually requiredA clear description of the goods delivered or services performed is required on all tax invoices. Sufficient detail must be provided for IR to verify the correct GST treatment was applied.
