Subdivision of the family section NZ: one off vs scheme
GST on a backyard cut is not decided by council consent, and it is not the same test as income tax on land. Inland Revenue looks at whether the subdivision is a taxable activity: an activity carried on continuously or regularly that involves, or is intended to involve, supplies for consideration.
Kiwis talk about a one off family section versus a scheme of development. That everyday split is useful, but it is not a GST Act heading. The legal question is in section 6 of the Goods and Services Tax Act 1985. If the cut is not a taxable activity, you do not charge GST on the lot sale and you do not claim GST on the surveyor, lawyer, or council invoices. If it is a taxable activity, a land sale will usually push you over the $60,000 registration threshold, so you will likely need to register and charge GST.
The GST test in one paragraph
Inland Revenue question we have been asked QB 24/04, issued 21 June 2024, replaces the 1995 Newman Tax Information Bulletin item. One supply is usually a one off activity. Four or more lots are usually a taxable activity unless the activity is very low. Two or three lots sit in the middle: scale, development work, time, effort, and repetition decide it. Commercial flavour does not.
One off family cut versus a scheme
A one off family cut is usually outside GST. A repeating or multi lot scheme is usually inside GST. Category home: Property & Assets GST Hub. The full Commissioner view is QB 24/04 on Tax Technical, with the accompanying fact sheet issued 25 June 2024.
Usually one off
Family section, one sale
You live on the front lot. You create one extra title and sell it. Council still wants services and a driveway. That work does not, by itself, make the activity continuous or regular.
- One supply, not repeated
- Ordinary house on the new lot is still not enough
- Work on the house you keep does not count
- Being a GST registered builder or tradie does not automatically pull this sale into that other activity
Usually a scheme
Repeated or multi lot project
You create several saleable lots, or you keep buying land, cutting it, and selling it. The GST Act does not need a profit slogan. Private assets sold continuously or regularly can still be a taxable activity.
- Four or more lots: usually GST unless activity is very low
- Repeating one lot cuts over time: regularly
- Done in the course of an existing property development activity: GST even if the cut itself looks small
- Very high single supply (large office or apartment block): can still be GST
QB 24/04 is explicit: there is no specific lot number that decides every file. The more lots you sell, the less extra activity Inland Revenue needs before the project looks continuous or regular. Wider GST definition: taxable activity, hobby vs business. Developer context: GST for property developers and investors.
How many lots, and how much work?
Start with how many lots you create and sell, then weigh the activity. That two step method is the spine of QB 24/04 and the fact sheet diagram.
| Lots sold | QB 24/04 starting point | What still matters |
|---|---|---|
| One | Usually one off, not continuous or regular | Only a very high project (large office or apartment block) flips this. An ordinary dwelling does not. |
| Two or three | Borderline. Activity level decides it. | Scale, earthworks and services, time and effort, cost as support, and whether you will repeat it. |
| Four or more | Usually a taxable activity | A very low activity project can still sit outside. Unsold lots you intended to sell still count. |
Relevant factors in the fact sheet: scale; physical development (earthworks, roading, infrastructure, fences, buildings); time and effort, including arranging consent and engaging lawyers and surveyors; financial investment (weak on its own); and repetition. Buying land specifically to cut and sell often means more upfront cost and effort than cutting the section you already live on.
Not relevant: whether the job “looks commercial”; work done before you intended to sell; work on land you do not sell. If you later change your mind and sell a house you had meant to live in, only the work after that change counts. You have to prove when the intention changed.
Pull highlight: Newman v CIR (Court of Appeal, 1995) was a GST registered builder on 2.7 hectares who sold one lot after minimal drainage and electrical work. That sale was not a taxable activity. Wakelin v CIR (High Court, 1997) was six residential lots, with five sales over following years, and not a great deal of work. That was a taxable activity. Lot count did the heavy lifting.
Council consent is not the GST test
Getting a title is a Resource Management Act 1991 process. It does not tell you whether GST applies. Quality Planning treats subdivision as dividing a parcel or changing a boundary, then creating saleable certificates of title. Under section 11 of that Act you generally need a plan rule or a resource consent, plus a survey plan under Part 10.
Typical conditions include services, driveways, development contributions, easements, and bonds. A licensed cadastral surveyor prepares the plan. The territorial authority checks it under section 223, then certifies conditions under section 224(c). Land Information New Zealand then deposits the plan and issues titles. That path is the same whether you sell to a stranger or to a child. GST still sits on section 6 of the GST Act, not on the s 224(c) stamp. Process outline: Quality Planning, introduction to subdivision.
Selling the new lot to a family member
A family buyer does not skip GST. If you sell the lot for consideration, that is still a supply. The one off versus scheme test is unchanged. If the project is a taxable activity, GST can apply even when the purchaser is your child. If it is not a taxable activity, you still do not charge GST just because a lawyer used “plus GST, if any” on the agreement.
Income tax can still care about associated persons if you are linked to someone in the property industry. That is a different statute. GST associated person rules: associated persons GST.
Already GST registered?
Registration for another trade does not automatically GST the backyard. QB 24/04 says you still ask whether the subdivision was carried on in the course or furtherance of that existing taxable activity. In the Newman line of facts, the builder’s taxable activity did not swallow the family lot sale. Inland Revenue’s Example 2 (Jensen) is a GST registered ventilation sole trader who subdivides, builds two townhouses, lives in one, and sells the other: the cut is not part of the ventilation activity, and the one lot sale is not itself a taxable activity.
The other way round is Example 4: a GST registered residential development partnership that buys a house, cuts a backyard lot with only the minimum Wellington City Council work, and sells that lot to fund the renovation. That lot sale is a taxable supply because it is part of the existing development activity, even though the cut would not have been a taxable activity on its own.
Preparatory steps (survey, consent, early contractors) can form part of a taxable activity under section 6(2), so you can register for GST in NZ from early in a real scheme. If the project never leaves those steps, or it turns out not to be a taxable activity, Inland Revenue may cancel registration from the date you first registered. You are then not entitled to the input tax you claimed. Filing start dates sit in SPS 18/03 and the GST guide IR375.
GST and income tax are different taxes
QB 24/04 only answers GST. Inland Revenue’s subdividing and developing property to sell page (last updated 31 March 2025) is mostly income tax. That page looks at a pattern of buying and selling, intention when you bought, the bright line test, the dealers’ 10 year rule, partitioning of co owned land, association with a dealer or builder, and whether development or division within 10 years is more than minor (interpretation statement IS 20/08). “Minor” on that page is not the GST one off test. A sale can be outside GST and still be income. Guide IR361 covers property transactions for income tax.
In practice
Use case: Auckland rear lot (QB 24/04 Example 1 shape)
Situation: A couple who are not GST registered have lived in the house for years. They cut the section into two, meet Auckland Council consent conditions (sealed access, drainage, water, wastewater, power), pay surveyors and development contributions, keep the front house, and sell the rear title. GST: Not a taxable activity. One supply, one off, even with real council work. Action: Do not claim GST on those invoices. Still check income tax on the Inland Revenue subdividing page.
Use case: Hamilton three extra lots (QB 24/04 Example 1B shape)
Situation: Same family home facts, but the section yields three extra lots, more levelling, and a longer driveway. They sell all three and stay on the front. GST: Likely a taxable activity. Inland Revenue calls this borderline and wants a full factual analysis. Action: Get advice before you register or claim refunds. If it is a taxable activity, a land sale will usually exceed $60,000, so registration is likely.
Use case: inherited block into six lots (QB 24/04 Example 3 shape)
Situation: After a change of plan, the owner surveys, consents, builds a road and services, and cuts six lots over three years. Four sell; two sit on the market. GST: Yes, a taxable activity of subdivision. Intended supplies were six lots. Unsold lots still count. Fits and starts do not break continuity if the project never ceased. Action: Register, charge GST on taxable lot sales, and consider compulsory zero rating of land if the buyer is also registered and the settlement tests are met.
The refund trap
You cannot invent a taxable activity so you can claim GST on consent, engineering, and LINZ fees. Property forums keep mixing that up with income tax. No taxable activity means no GST registration on the normal path, and no input tax. If you already registered and the cut is not a taxable activity, QB 24/04 says registration may be cancelled from the start. Keep the house you live in out of the activity count. Long term residential rent of a dwelling you keep is generally an exempt supply, not a GST claim engine: GST on residential rent in NZ.
Registration, $60,000, and plus GST if any
On Inland Revenue’s registering for GST page you must register if you carry out a taxable activity and turnover was at least $60,000 in the last 12 months, or you expect it will be in the next 12 months, or you add GST to your prices. The QB 24/04 fact sheet says a land sale will usually exceed that threshold, so a taxable subdivision usually means you register. Threshold walkthrough: $60,000 GST threshold guide.
Inland Revenue’s charging GST page says registered persons charge GST at 15% on most taxable supplies, either $100 plus GST ($115) or GST inclusive (3/23). Land sales can instead be zero rated when the compulsory land tests are met. Agreements that say plus GST, if any, do not create GST if there is no taxable activity. They also do not override compulsory zero rating when those tests are met. If you only need to add or strip 15% on a figure that is already in the GST net, use the free GST calculator.

Repeating small cuts can still be GST. QB 24/04 Example 5 is a person who buys coastal land, splits it, sells the bare lots, then repeats on the next parcels with little physical work. The first cut might not have been enough on its own. The pattern makes the activity regular.
What people get stuck on
Forum threads treat “the accountant said it is not taxable because we used the money to pay down the mortgage” as a GST answer. It is not. GST does not care how you spend the proceeds. Threads also treat income tax “minor work” or a 10 year hold as the GST test. Separate those files. Geekzone “plus GST if applicable” only matters once a taxable activity exists. Zero rating between two registered parties is compulsory land zero rating, not a handshake to skip GST.
Section 76 of the GST Act can still void a tax avoidance arrangement. Do not structure a family transfer only to manufacture input tax or to park a scheme outside section 6.
FAQs
Do I charge GST when I subdivide my family section in New Zealand?
Only if the subdivision is a taxable activity under section 6 of the GST Act 1985. Inland Revenue QB 24/04 says a project that leads to only one sale is usually a one off activity, not continuous or regular, unless the level of activity is very high, such as building and selling a large office building or apartment block. Building and selling an ordinary residential dwelling on subdivided land is not enough.
Is cutting off two or three backyard lots a GST taxable activity?
It depends on the facts. QB 24/04 says two or three lots make the level of activity especially important. Four or more lots are usually a taxable activity unless the activity is very low. There is no magic lot number that decides every case.
Can I claim GST on surveyor and council fees for a family section cut?
Not unless you are carrying on a taxable activity of subdivision, or the work is done in the course or furtherance of another taxable activity you already have. QB 24/04 says if you register on the basis of preparatory steps and the project is not a taxable activity, Inland Revenue may cancel registration from the start and you are not entitled to those input tax claims.
Does selling the new lot to a family member change the GST answer?
No. A sale to a relative for consideration is still a supply. GST still turns on whether you are carrying on a taxable activity, not on whether the buyer is family. Council consent, survey plans, and Land Information New Zealand titles are the same process either way.
