1. Background and purpose of the guideline

On 5 May 2026, Inland Revenue New Zealand released an exposure draft interpretation guideline titled“GST – Types of unincorporated bodies” (PUB00530) for public consultation. The draft aims to support taxpayers in determining which GST rules apply to their particular arrangements where activities are carried out jointly by more than one person without forming a company. [taxtechnic…rd.govt.nz]

For GST purposes, an unincorporated body is treated as a separate“person” under the Goods and Services Tax Act 1985 (GSTA). This classification has significant implications for GST registration, invoicing, and return filing. However, not all collective arrangements automatically qualify as unincorporated bodies—particularly where arrangements are limited to cost‑sharing or passive co‑ownership. The guideline seeks to draw clearer boundaries between these scenarios. [taxtechnic…rd.govt.nz]

2. What qualifies as an unincorporated body for GST?

The guideline explains that the statutory definition of “unincorporated body” is inclusive and covers:

• Partnerships
• Joint ventures
• Trustees of a trust
• Other unincorporated bodies that do not neatly fall into the above categories (such as clubs or syndicates)

Importantly, this means that even if an arrangement is not labelled a partnership or joint venture, it may still be treated as an unincorporated body for GST if its substance supports that conclusion. Conversely, simple co‑ownership or cost‑sharing arrangements will not necessarily meet this threshold. [taxtechnic…rd.govt.nz]

Where an unincorporated body carries on a taxable activity:

• The body itself must be registered for GST, not its individual members.
• Supplies made in the course of that activity are deemed to be made by the body.
• Supplies between the body and its members, where members act in their capacity as members, are also treated as supplies to or by the body rather than the individuals. [taxtechnic…rd.govt.nz]

3. Partnerships and GST implications

The draft devotes considerable attention to partnerships, defined as persons carrying on a business in common with a view to profit under the Partnership Law Act 2019. Whether a partnership exists depends on the totality of the facts and conduct, not merely contractual labels. [taxtechnic…rd.govt.nz]

Key clarifications include:

• Co‑ownership of property, even with profit‑sharing, does not automatically create a partnership.
• Mutual agency, shared decision‑making, and joint exposure to profits and losses are critical indicators.
• Many partnerships arise informally, even without a written agreement, making GST classification particularly sensitive in practice.

The guideline uses examples to distinguish partnerships from mere co‑ownership, which is especially relevant for property syndicates, infrastructure projects, and investment structures. [taxtechnic…rd.govt.nz]

4. Joint ventures and flow‑through treatment

The draft also addresses joint ventures, highlighting the distinction between:

• Ordinary joint ventures, which are treated as unincorporated bodies and fall under section 57 GSTA; and
• Flow‑through joint ventures, where members elect under section 57B to account individually for their share of supplies and acquisitions.

This distinction can materially affect compliance obligations, including VAT reporting, cash‑flow, and audit exposure. The guidance therefore emphasizes the need for taxpayers to clearly document the nature of their joint venture arrangements. [taxtechnic…rd.govt.nz]

5. Other unincorporated bodies and practical implications

Beyond partnerships, joint ventures, and trusts, the draft recognises that other unincorporated bodies—such as clubs or syndicates—may also fall within the GST definition of an unincorporated body. Determining the correct classification requires an assessment of:

• The parties’ intentions
• Contractual rights and obligations
• How the arrangement operates in practice, including dealings with third parties

IRD stresses that taxpayers must be able to evidence the nature of their arrangement to support their GST position, increasing the importance of governance documentation and internal controls. [taxtechnic…rd.govt.nz]

6. Consultation and next steps

The exposure draft PUB00530 is open for comment until 17 June 2026. IRD encourages submissions that address both technical accuracy and practical application issues. Final guidance will replace earlier uncertainty in this area and is expected to be particularly relevant for:

• Property co‑investment structures
• Large infrastructure projects
• Cost‑sharing and collaborative operating models
