Free GST Invoice Generator NZ — No Sign-up
Create professional, IRD-compliant tax invoices in seconds. The fast, 100% free way for NZ sole traders and small businesses to generate branded PDF invoices.
Free GST Invoice Template & IRD Compliance
Ensuring your invoices meet IRD standards is the first step to a smooth tax year. Our generator follows the strict requirements of the GST Act 1985.
Contract Labour Invoicing
A plumber completes a job at $80/hr for 10 hours. He uses the generator to list "Labour" at $800. The tool automatically adds $120 GST (15%). He downloads the PDF, sends it to the client, and keeps the itemized record for his 2-monthly filing.
Mixed Supply Invoices
A web agency invoices for "Website Hosting" ($50/mo) and "Consulting" ($150/hr). By listing these as separate line items, they provide a professional breakdown for their client, ensuring the client's own bookkeeper can easily claim the input tax credit.
IRD Tax Invoice Requirements by Value
| Invoice Total | Mandatory Elements | Key Rule |
|---|---|---|
| Under $50 | No tax invoice required | Simple receipt or record is sufficient for your records. |
| $50 to $1,000 | "Tax Invoice", GST Number, Date, Supplier Name, Description, GST Amount | The most common range for small business transactions. |
| Over $1,000 | All of the above + Buyer's Name, Buyer's Address | Mandatory for clients to claim a GST input tax credit over $1,000. |
Pro Tip: Our generator automatically includes fields for the buyer's name and address, ensuring your invoices are compliant even for transactions exceeding $1,000.

- IRD Compliance: Includes the required 'Tax Invoice' label and GST number fields.
