Invoice Requirements in New Zealand: Legal Rules for 2026

TL;DR: New Zealand tax invoices must include your GST number, a description of the supply, and the 15% GST amount shown separately. Buyer details are required for supplies over NZD 1,000 -- retain tax invoices for at least seven years and monitor IRD for evolving digital requirements.

New Zealand GST is administered by Inland Revenue (IRD). Tax invoices enable registered buyers to claim input tax and support GST returns. Informal receipts often fail enterprise AP and IRD reviews. Cross-border remote services and marketplace rules add nuance for 2026 operators. This article is general guidance, not legal advice—confirm zero-rated exports, financial services, land transactions, and reverse charge-style rules with IRD or your adviser. Australian GST teams often compare NZ templates side by side—keep terminology distinct so cross-Tasman AP does not mis-post credits.

Required fields

Tax invoices generally show seller name and GST number, buyer name (and GST number for taxable supplies above NZD 1,000 including GST), date of issue, description of goods or services, taxable amount, GST charged, and total payable. Buyer address expectations depend on value—check current IRD guidance for simplified tax invoices and low-value rules. Credit notes must reference the original tax invoice and adjust GST transparently.

Tax rules (VAT/GST/sales tax rates)

The standard GST rate is 15%. Zero-rated exports and certain supplies carry 0% with evidence requirements. Exempt supplies (parts of financial services, residential rent, etc.) sit outside the credit chain—do not label them like standard taxable lines. Mixed supplies need clear allocation for both IRD and customer reconciliation. GST groups and agency arrangements must show which member issues the tax invoice so input credits attach to the correct registration—ambiguous letterheads frustrate refunds during group restructures. Imported services and certain remote digital supplies can shift liability under specific rules; do not assume domestic supply footers when reverse charge or marketplace mechanics apply.

Language requirements

English is the default for B2B and IRD correspondence. Bilingual documents are acceptable if GST figures remain unambiguous.

Digital invoicing rules

IRD expects readable electronic records supporting GST returns. Email PDFs are common; avoid overwriting files after issuance. Accounting exports should tie each tax invoice number to GST return boxes without ad hoc spreadsheets—breaks in that chain are common audit findings. Large buyers may require Peppol or portal UBL—align contractually required fields with your ERP output. IRD audits favour immutable PDF hashes or WORM storage when disputing issuance dates.

Invoice numbering rules

New Zealand GST law does not prescribe a specific numbering format, but tax invoices must be identifiable within your records. Sequential numbering is best practice -- IRD auditors expect to trace invoices to GST returns without gaps. You may use alphanumeric formats or series by business division. Credit notes and debit notes should carry their own identifiers and reference the original tax invoice number. Buyer-created tax invoices (where the recipient issues the invoice) are permitted under a written agreement and must follow the same content requirements. Businesses operating multiple trading names should ensure numbering is coordinated so that each GST registration maintains a clean, traceable sequence. Voided or cancelled invoices should be retained with explanations rather than deleted from the sequence.

Common exemptions and special cases

Businesses with taxable supplies below NZD 60,000 in a 12-month period are not required to register for GST, though they may register voluntarily. Once registered, standard tax invoice rules apply. Simplified tax invoices may be used for supplies of NZD 1,000 or less (inclusive of GST), with reduced buyer detail requirements. For supplies over NZD 1,000, the buyer's name and address (and GST number if registered) must appear on the tax invoice. Zero-rated supplies include exports of goods and certain services performed for non-residents -- these must be invoiced at 0% with supporting evidence. Exempt supplies (such as financial services and residential accommodation) sit outside the GST credit chain and must not show GST. Second-hand goods purchased from unregistered persons can support an input tax claim without a tax invoice under specific conditions -- the buyer must maintain their own records of the purchase. GST groups allow related companies to register as one GST entity, but the member issuing the tax invoice must be clearly identified. Remote services supplied by non-resident providers to NZ consumers over NZD 60,000 per annum require GST registration under the marketplace and remote services rules.

Record retention requirements

IRD requires retention of all business records, including tax invoices, for a minimum of seven years from the end of the income year to which they relate. If a dispute is ongoing or you have tax losses being carried forward, records should be retained until the matter is resolved plus the standard period. Records must be in English (or readily translatable) and accessible in New Zealand or readily producible when requested. Electronic records are acceptable if they are complete, accurate, and accessible -- IRD has published guidance on acceptable electronic record-keeping systems. Cloud storage is permitted if the records can be accessed promptly. For businesses using cash-basis accounting, retain tax invoices from the date of issue regardless of when payment occurs. Destroying records before the seven-year period can result in knowledge offence penalties and weakens your position in any dispute.

E-invoicing status

New Zealand does not currently mandate structured e-invoicing for all businesses. However, the New Zealand government has been actively promoting Peppol adoption for B2G procurement and is encouraging B2B uptake. The New Zealand Peppol Authority operates under the Ministry of Business, Innovation and Employment (MBIE), and government agencies have begun receiving Peppol e-invoices. The government has published a Business Case for E-invoicing and set adoption targets for public-sector procurement. Enterprise buyers are also driving adoption through procurement requirements. New Zealand and Australia are coordinating on trans-Tasman e-invoicing interoperability through Peppol, making it easier for businesses operating in both markets. While no mandate exists for private B2B, the infrastructure is in place, and businesses that adopt Peppol now benefit from faster payment processing and reduced data-entry errors. IRD's ongoing digital transformation programme may eventually integrate structured invoice data with GST return processes.

Penalties

IRD may charge use-of-money interest (UOMI) on underpaid tax at rates published periodically (typically 7% to 10% per annum for underpayments, with a lower rate for overpayments). Shortfall penalties apply when a GST return contains an error that results in less tax paid: 20% of the shortfall for lack of reasonable care, 40% for an unacceptable tax position, and 100% to 150% for gross carelessness, abusive tax position, or evasion. These can be reduced by up to 100% for voluntary disclosure before IRD initiates an audit, or up to 75% if disclosed after an audit is notified but before it is completed. Late filing penalties are NZD 50 initially, increasing with time (NZD 250 after further delay, and ongoing increments). Late payment penalties of 1% of the unpaid tax are charged on the day after the due date, with an additional 4% charged seven days later. Customers may delay payment when GST numbers or tax invoice wording is defective.

If you sell across the Tasman, run separate QA on NZ and Australian templates so GST labels, registration fields, and evidence wording never bleed across footers. Document who may approve credit notes and how those numbers feed the next GST return so AR and tax never maintain parallel unofficial sequences.

FAQ

What is the difference between a tax invoice and a regular invoice in New Zealand? A tax invoice is the specific document required under the GST Act that enables a registered buyer to claim an input tax deduction. It must include the words "tax invoice," your GST registration number, and other prescribed details. A regular invoice or receipt does not support GST credit claims. If you are GST-registered and make a taxable supply over NZD 50, the buyer can request a tax invoice and you must provide one within 28 days.

Do I need to register for GST if I only sell online? If your taxable supplies (online or offline) exceed NZD 60,000 in any 12-month period, you must register. For non-resident businesses providing remote services (such as digital products, streaming, or SaaS) to New Zealand consumers, the same NZD 60,000 threshold applies. Non-resident suppliers register under a simplified process and typically charge GST at the standard 15% rate.

Can I issue tax invoices in a foreign currency? Yes, but the GST amount must be converted to NZD using a consistent exchange rate method documented in your records. IRD accepts the rate published by a New Zealand bank on the date of the supply or an average rate method if applied consistently. The conversion approach should be noted for audit purposes.

What are buyer-created tax invoices? A buyer-created tax invoice is one issued by the recipient of the supply rather than the supplier. This is permitted when both parties have a written agreement in place. The document must include the same information as a standard tax invoice and must state that it is a buyer-created tax invoice. This arrangement is common in primary industries (such as forestry and agriculture) where the buyer processes goods and knows the final value only after processing.
