Land Tainting Rules
How Land Owning Structures Become “Accidentally Tainted” Over Time
One of the more difficult aspects of New Zealand’s land taxing regime is that land can be taxable not only because of the owner’s activities, but also because of historic activities, associated persons, or prior transactions elsewhere within the wider ownership structure.
In practice, many land tax exposures arise gradually over time as family groups accumulate trusts, companies, financing arrangements and historic development activity. The result is that land commercially viewed as a long-term passive investment, including family homes, can nevertheless become taxable under the land taxing provisions, in some cases regardless of how long it has been owned.
One of the common misconceptions in practice is analysing the land taxing provisions in isolation. Unfortunately, the provisions frequently overlap and are significantly widened by the associated persons rules. Land originally acquired for long-term investment purposes may subsequently become exposed due to subdivision or development activity, land held by a passive entity may become taxable because of associations with a builder elsewhere within the wider group, and land transferred between associated entities may inherit historic ‘taint’ from the vendor under section CB 15.
Section CB 15 can apply where land is acquired from an associated dealer, developer, subdivider or builder, with the result that the purchaser effectively inherits the vendor’s land tax profile.
Section CB 15 – The Tagging Provision
We have frequently been seeing the application of section CB 15. Broadly, section CB 15 can apply where:
- land is acquired from an associated person; and
- that land sale was taxable to the associated vendor.
In effect, the purchaser inherits the vendor’s land tax obligations. Section CB 15 prevents taxpayers avoiding the land taxing provisions by transferring land to an associated person or entity.
For example:
- Vendor held land as trading stock. Section CB 6 applied to the sale because it was acquired with an intention of disposal;
- A transfer to an associated person does not cleanse that ‘taint’;
- Instead, the associated purchaser effectively steps into the vendor’s position.
The land effectively inherits the tax profile of the associated vendor.
As the vendor would have been taxable on a future sale under section CB 6, the associated purchaser will also remain taxable regardless of how long the land is subsequently owned.
By contrast, where the vendor was subject to a time-limited provision (e.g. one of the ten-year rules), the associated purchaser generally inherits that same timeframe rather than restarting a fresh or permanent taint.
Section CB 15 can also produce harsh outcomes because the ordinary exclusions do not apply.
In some cases, it may be preferable to leave the land in its existing structure.
This is an area where obtaining specific advice is critical. The correct answer depends heavily on the precise land taxing provisions in play and the historic facts surrounding both the land and the wider ownership structure.
The Associated Persons Rules Are Often the Real Issue
In many land tax cases, the core issue is not the substantive land activity itself, but the breadth of the associated persons rules.
For trusts and closely held entities, the rules can create associations through:
- common settlors;
- trustee relationships;
- shareholder interests;
- partnership interests;
- financing arrangements;
- and tripartite association provisions.
Importantly, taxpayers frequently create associations unintentionally.
Deemed settlors
One of the most misunderstood aspects of the associated persons rules is how easily individuals and entities can become “deemed settlors” of a trust under the Income Tax Act. In practice, many family groups inadvertently create associations through ordinary funding and family arrangements, without appreciating the downstream land tax consequences.
A common example is where a person advances funds to a trust interest-free, or at an interest rate below the prescribed rate. In many circumstances, that person will become a deemed settlor of the trust because they have provided financial assistance for less than market value. Similarly:
- Gifting funds or property to a child’s trust will result in a deemed settlor status;
- A beneficiary with a current account balance exceeding $25,000 (Trust owes beneficiary) where no interest is charged will become a deemed settlor;
- Interest free loans between trusts will also create a deemed settlement – in which case the trusts will have common settlors.
The consequences are often far wider than taxpayers expect. Once two trusts have a common settlor, including a deemed settlor, the trusts become associated under section YB 7.
Those associations can then flow through to companies, partnerships and other trusts elsewhere within the wider family structure through the tripartite association rules.
We have seen numerous examples of this over the last year in family groups with historic development or building entities. The families often believed the land was safely outside the income tax net because it had been held long-term as residential investment property or even as a family home. However, the associated persons rules resulted in section CB 15 applying because the land had been purchased from an associated dealer, developer, or subdivider. The main home exemption was not available.
Example – Hidden Settlor Associations
In a recent case, multiple land-owning entities had operated independently for many years. The family believed the entities were separate investment structures, that historic development activity had been quarantined elsewhere within the wider group, and that the landholding entities themselves were merely passive.
However, over a long period the entities had advanced funds between each other. Those funding arrangements created deemed settlor relationships, trust associations under section YB 7, and indirect tripartite associations under the associated persons rules. As a result, land that was thought to be “clean” remained associated with historic development entities.
In this case, a child’s trust had purchased land from an associated family development trust (which held the land as trading stock). The family believed the land was safely outside the income tax net because it had subsequently been used as the child’s family home. However, because the trusts had inadvertently become associated through historic funding arrangements, section CB 15 applied. This meant a future sale by the child’s trust could remain taxable because the trust inherited the development trust’s land tax profile, despite the land being held long-term as a family home.
Importantly, the exposure arose gradually over time through ordinary family financing arrangements rather than any deliberate tax planning.
Key Practical Takeaways for Advisers
Some recurring themes we are seeing:
- historic transactions are often poorly documented;
- families frequently underestimate how wide the associated persons rules are;
- “passive” rental structures may still carry historic taint;
- ordinary funding arrangements can create unintended associations;
- land tax risks are often inherited from earlier generations or prior restructures.
Importantly, these issues rarely arise because clients were trying to avoid tax. Most structures simply evolved over time without anyone reassessing how the land taxing provisions applied to the wider group.
Final Thoughts
In practice, many land-owning structures become “accidentally tainted” over time through ordinary commercial, succession, and financing decisions that were never revisited from a land tax perspective.
For land dealers, developers, subdividers and builders, regular review of the wider ownership structure is critical. Without careful management, otherwise passive investment assets can become unintentionally associated with development entities or inherit historic taint under the land taxing provisions. Groups operating in this space should ensure they have clear guidance around ownership structures, funding arrangements, land transfers and associated person exposures, with periodic reviews undertaken as the group evolves. Identifying and managing these risks early is significantly easier than attempting to unwind historic issues after a sale or restructure is already underway.
