Outside the land sale rules, but still taxable?
Inland Revenue’s revised view of section CB 3 could widen the tax net for property sales, developments and subdivisions.
Inland Revenue has signalled a significant shift in how it may tax profits from property sales. In its revised draft Interpretation Statement, PUB00519, Inland Revenue argues that a land sale can be taxed under the broader profit-making undertaking or scheme provision in section CB 3 of the Income Tax Act 2007, even where the specific land sale rules do not apply.
Inland Revenue’s view is that the specific land sale rules are not a complete code. A sale may therefore still be taxable under section CB 3 if it forms part of a profit-making undertaking or scheme. This is a significant departure from Inland Revenue’s earlier position and potentially increases the tax exposure arising from property developments, subdivisions and substantial renovation projects.
More controversially, section CB 3 could apply even where a sale qualifies for a residential, business premises, farming or investment exclusion under one of the specific land sale provisions. In other words, falling outside of, or within an exclusion from, the land sale rules may not mean the sale is not taxable.
What does section CB 3 tax?
Section CB 3 can tax any profit from carrying on any plan or undertaking done by a person with a dominant intention to make a profit. For example, section CB 3 could tax a one-off trade of an asset such as a car, or buying gold, or crypto.
Although section CB 3 is not specifically a land sale provision, Inland Revenue considers its wording is wide enough to also apply to tax land sales.
This is important because section CB 3 can apply to a project that begins well after the property was acquired. It is not limited to circumstances where the taxpayer acquired the property with an intention or purpose of resale. A property initially acquired as a home, rental investment, farm or business premises may later become part of a profit-making undertaking or scheme to bring it into the scope of section CB 3.
Inland Revenue’s previous position
In its December 2024 Questions We’ve Been Asked, Inland Revenue considered sections CB 12 and CB 13 to be the specific provisions governing undertakings or schemes involving the development or division of land.
Section CB 12 generally applies to an undertaking or scheme involving development or division that:
- Begins within 10 years after the land was acquired; and
- Involves development or division work that is more than minor.
Section CB 13 can apply where an undertaking or scheme begins more than 10 years after acquisition and involves significant expenditure on specified development or division work.
Inland Revenue’s previous reasoning was that:
- Sections CB 12 and CB 13 were specific provisions dealing with development and subdivision undertakings.
- Section CB 3 was a more general profit-making scheme provision.
- A specific provision ordinarily takes priority over a general provision.
- Section CB 3 should therefore not apply to an undertaking or scheme involving the development or division of land if the undertaking was within the subject matter of sections CB 12 and CB 13.
Under that approach, if a subdivision or development undertaking did not satisfy the requirements of sections CB 12 or CB 13, section CB 3 should not generally have applied as an alternative way of taxing the same activity.
Inland Revenue’s new position
Inland Revenue has changed its view. Inland Revenue has now adopted the broader view that the specific land sale rules do not form a complete code for taxing land disposals, and that section CB 3 can operate as a potential catch-all for profit-making property projects that fall outside the specific land sale rules.
Inland Revenue’s revised approach is:
1. The specific land sale provisions must be considered first.
2. If a specific land sale provision applies, it takes priority over section CB 3.
3. If no specific land sale provision applies, section CB 3 needs to be considered.
4. An exclusion from a specific land sale provision does not automatically prevent section CB 3 from applying.
5. Section CB 3 may apply where there is a profit-making undertaking or scheme that is separate from the capital use of the land protected by the exclusion.
What about the land sale exclusions?
Whilst there are specific exclusions in the land taxing provisions (e.g., residential land, farmland, business premises, investment land etc), there are no exclusions for section CB 3.
The exclusions protect the capital use of the land. For example, they may protect land genuinely used as a residence, farm, business premises or long-term investment.
Inland Revenue’s argument is that the exclusions do not protect a separate undertaking or scheme entered into for the dominant purpose of making a profit.
The distinction is between:
- Selling land that has been used as a capital asset; and
- Carrying out a separate profit-making project involving that land.
If the owner merely sells a home, farm, rental property or business premises at the best available price, section CB 3 should not apply. If the owner undertakes a separate project to create something new or substantially transform the property for sale, section CB 3 may apply to transform what would otherwise be a capital sale to taxable income.
The three requirements of section CB 3
Inland Revenue identifies three requirements that must be satisfied before section CB 3 can apply to a land disposal.
1. The disposal must be part of an undertaking or scheme
An undertaking or scheme is a plan, design or programme of action devised to attain an end result. It requires a coherent plan involving a series of steps directed towards that result. This is not a high threshold.
A one-off property project can be an undertaking or scheme. The taxpayer does not need to be carrying on a property development business or have undertaken similar projects previously.
2. The dominant purpose must be making a profit
A taxpayer may have more than one purpose for undertaking a project, but making a profit must be the dominant or main purpose.
The focus is on the taxpayer’s subjective purpose when the undertaking or scheme begins, not the purpose envisaged when the land was originally acquired. A new undertaking or scheme can begin many years later.
3. The sale must be more than the mere realisation of a capital asset
Section CB 3 should not tax the ‘mere realisation’ of a capital asset, including realising an asset at its best advantage.
A property owner is entitled to take reasonable steps to maximise the sale price or make the property more attractive to purchasers.
The distinction is whether the taxpayer is:
- Merely disposing of the existing asset in the most advantageous way; or
- Creating something new or significantly changing the character of the asset.
The boundary is not always clear.
Activities likely to be mere realisation
Inland Revenue considers the following activities are more likely to remain the mere realisation of a capital asset:
- A subdivision that does not involve significant work.
- Minor work required to obtain subdivision consent.
- Undertaking ordinary repairs before sale.
- Repainting and recarpeting.
- Replacing fixtures.
- Updating a kitchen or bathroom.
- Completing delayed maintenance.
- Other renovations typically undertaken to prepare a property for sale.
The fact that work is undertaken to increase the sale price does not, by itself, make the resulting gain taxable under section CB 3.
Activities likely to go beyond mere realisation
An undertaking or scheme is more likely to go beyond mere realisation where it involves, for example:
- An extensive subdivision with substantial infrastructure.
- Constructing one or more new dwellings.
- Completely rebuilding or transforming an existing dwelling.
- Constructing a substantial extension.
- Fundamentally changing the property’s size, layout, use or character.
- Creating a materially different asset for sale.
This does not mean that every new build or substantial renovation is taxable. The project must still have been undertaken for the dominant purpose of making a profit.
Example 1: a builder constructs their own home.
Sylvia carries on a business of erecting buildings. She purchases land, constructs a house and lives in it as her home. She later sells the property within 10 years after completing the improvements.
Section CB 11 would ordinarily be relevant because Sylvia is in the business of erecting buildings and sells within 10 years after completing the improvements.
However, the residential exclusion applies because Sylvia genuinely used the property as her residence.
On the facts in PUB00519, section CB 3 also does not apply.
Although building the house was an undertaking or scheme, Sylvia did not undertake the project for the dominant purpose of making a profit. Her purpose was to create a home in which to live. The later sale was the mere realisation of her capital asset.
However, the result could be different if the evidence showed that Sylvia built the house primarily to sell it for a profit and any occupation of the property was temporary or incidental to that plan.
In that case, the residential exclusion would not prevent section CB 3 from applying. Inland Revenue would examine whether there was a separate profit-making undertaking or scheme involving construction and sale.
Example 2: demolishing a home and building two new dwellings.
Jensen has lived in his home for 12 years. He decides to demolish the existing house, subdivide the land into two lots and construct two new dwellings.
Jensen intends to live in one dwelling and sell the other.
Section CB 12 does not apply because the undertaking begins more than 10 years after Jensen acquired the land.
The example assumes section CB 13 does not apply because the relevant development or division work does not meet its significant expenditure requirements.
Under Inland Revenue’s previous approach, there was a stronger argument that section CB 3 could not be used to tax a subdivision falling outside sections CB 12 and CB 13.
Under Inland Revenue’s revised position, section CB 3 applies.
Constructing the new dwelling for sale creates something new on the land and fundamentally changes the character of that part of the property. It goes beyond merely realising the existing land at its best advantage.
Jensen’s purpose is tested in relation to the part of the land intended for sale. Although Jensen intends to live in one of the new dwellings, his dominant purpose in constructing the second dwelling is to make a profit from its sale.
Example 3: acquiring neighbouring land for resale.
Sam owns land on the outskirts of a growing town. He becomes aware that a property developer is looking for a large block of land in the area.
Sam acquires the neighbouring farm with the intention of combining it with his existing land and selling both properties to the developer for a profit.
Section CB 6 applies to the sale of the neighbouring farm because Sam acquired that land with the purpose or intention of disposal.
Section CB 3 could also apply because the acquisition and proposed sale form a coherent profit-making undertaking or scheme. However, because section CB 6 is the more specific land sale provision, the sale of the neighbouring farm should be taxed under section CB 6.
Neither section CB 6 nor section CB 3 applies to Sam’s original land.
Sam did not acquire the original land with a purpose or intention of disposal, so section CB 6 does not apply. Its sale is also the mere realisation of an existing capital asset at its best advantage, rather than an amount derived from the profit-making scheme involving the acquisition of the neighbouring farm.
This demonstrates that the relevant undertaking or scheme, and the land subject to it, must be identified carefully. A profit-making scheme involving one property does not automatically make the sale of all related land taxable.
Summary
The key change in PUB00519 is Inland Revenue’s conclusion that the land sale rules are not a complete code. This has significantly increased the risk for landowners when they are looking at ways to improve their return on sale.
Sections CB 12 and CB 13 were previously regarded as the specific and comprehensive provisions governing undertakings or schemes involving land development or subdivision. Inland Revenue now considers those provisions supplement section CB 3 rather than replace it.
More broadly, the failure of any specific land sale provision to apply does not prevent section CB 3 from applying.
Inland Revenue accepts that, in most cases, a sale qualifying for a land sale exclusion should also fall outside section CB 3. The ordinary sale of a home, farm, business premises or investment property should generally remain the mere realisation of a capital asset.
The risk arises where the taxpayer undertakes a separate project for the dominant purpose of making a profit and creates something new or significantly changes the property’s character. For example, where a taxpayer:
- Subdivides long-held land.
- Constructs a new dwelling for sale.
- Demolishes and replaces an existing dwelling.
- Undertakes a major extension or conversion.
- Substantially transforms a rental property before sale.
- Carries out a one-off project that has the features of a commercial property venture.
Anyone considering subdividing, constructing or substantially renovating a property for sale should obtain tax advice before the project begins. Early advice can help identify the relevant undertaking or scheme, document the taxpayer’s purpose, determine when the scheme starts and ensure appropriate valuation evidence is retained.
