WHEN CAN LAND SALES BE TAXED AS A PROFIT-MAKING SCHEME?

When can land sales be taxed as a profit-making scheme? Inland Revenue has released a draft interpretation statement, PUB00519, that revisits an issue which has been debated by tax advisors, property investors, developers, and Inland Revenue itself for decades. And it is potentially a huge shift in IRD thinking.

At the heart of the draft is a deceptively simple question:

Can section CB 3 of the Income Tax Act 2007 tax a gain from the sale of land, even when none of the specific land sale provisions apply?

In a draft “Questions We’ve Been Asked” item released in December 2024, Inland Revenue’s preliminary view suggested that where sections CB 12 and CB 13 did not apply to a transaction, section CB 3 generally would not be used to tax the disposal.

That position has now changed.

The Commissioner’s current view is that the specific land sale provisions are not a complete code for taxing land disposals. Instead, section CB 3 can potentially operate independently and tax land sales in certain circumstances. While Inland Revenue stresses that this outcome will arise only in limited situations, the proposal is likely to impact at least some investors. It potentially expands the circumstances in which a land disposal can be challenged and raises questions about certainty in an already complex area of tax law.

Why Is Relevant to Investors?

The tax treatment of land transactions has always been one of the most heavily litigated areas of New Zealand tax law. The specific land sale rules are contained in sections CB 6A through CB 23B of the Income Tax Act. These provisions cover a wide range of scenarios, including:

• Bright-line sales
• Property dealing activities
• Property development businesses
• Land subdivision activities
• Builders and developers
• Associated person transactions

Importantly, those provisions also include a number of exclusions. Depending on the circumstances, exemptions may apply for:

• Family homes
• Main residences
• Business premises
• Farmland
• Certain investment properties

Because Parliament created an extensive set of detailed land sale rules, many advisers have long questioned whether those provisions effectively form a complete code. The argument is straightforward: If Parliament has created specific rules for taxing land, shouldn’t the tax analysis stop there? If none of those rules apply, doesn’t that mean the disposal is non-taxable?

Inland Revenue’s new draft suggests otherwise. The Commissioner now says that section CB 3 remains available as a separate taxing provision, even where none of the specific land sale provisions apply. That is a significant conclusion. Why is this relevant to investors? It means the sale of your residential property might be taxed, whereas previously it would not have been.

So, when can land sales be taxed as a profit-making scheme? First, let’s discuss Section CB 3 of the Income Tax Act.

What Is Section CB 3?

Section CB 3 is often referred to as the profit-making undertaking or scheme provision. In broad terms, it taxes profits derived from carrying out an undertaking or scheme where the dominant purpose is making a profit. Unlike many of the land sale provisions, section CB 3 is not specifically directed at land. Instead, it is a general provision capable of applying to a wide range of transactions and ventures. Historically, it has been used where taxpayers undertake projects that are more than simply holding and disposing of capital assets. The challenge is that the boundaries of section CB 3 can sometimes be difficult to define, particularly when applied to residential property transactions.

Why Inland Revenue Says Section CB 3 Can Apply

The draft interpretation statement advances several reasons why section CB 3 can operate alongside the land sale provisions rather than being displaced by them.

• The Wording of the Legislation

The Commissioner begins with the text itself. Section CB 3 taxes “any amount” derived from carrying out a profit-making undertaking or scheme. Nothing within the statutory language explicitly states that land transactions are excluded. Equally, the land sale rules do not say they are the exclusive route for taxing gains on land. From a statutory interpretation perspective, Inland Revenue argues there is simply no express conflict between the provisions.

• Legislative History

The draft also relies heavily on the history of the land sale rules. When Parliament introduced major changes to the land taxing provisions in 1973, lawmakers described the reforms as strengthening existing taxation measures rather than replacing them altogether. According to Inland Revenue, that history indicates Parliament intended the land sale rules to supplement the existing framework instead of displacing broader taxing provisions such as section CB 3.

• Existing Case Law

The Commissioner also points to judicial decisions. Courts have historically applied predecessor versions of section CB 3 to land-related transactions even after the expansion of the specific land sale rules. While the cases are fact-specific, Inland Revenue argues they demonstrate judicial acceptance that a profit-making scheme provision can coexist with the land taxing regime.

• No True Conflict with Sections CB 12 and CB 13

Some advisers have argued that sections CB 12 and CB 13 already deal with development and subdivision activities. If those provisions do not apply, perhaps that should be the end of the matter. Inland Revenue disagrees. According to the draft, sections CB 12 and CB 13 serve different purposes and contain different requirements. For example, section CB 12 does not require an intention to make a profit. Section CB 3 does. Because the provisions have different elements, Inland Revenue believes they address different situations and therefore do not overlap in a way that would prevent section CB 3 from applying.

When Will Section CB 3 Apply?

While the draft interpretation statement broadens the potential reach of section CB 3, it does not suggest every profitable land sale becomes taxable. Three key conditions must be satisfied.

• There Must Be an Undertaking or Scheme

The first requirement is an undertaking or scheme. This concept is interpreted broadly. A taxpayer does not need to have a formal business plan or corporate structure. A coordinated plan of action designed to achieve a particular outcome can be sufficient. In practice, this threshold is unlikely to create much difficulty for Inland Revenue.

• The Dominant Purpose Must Be Making a Profit

The second requirement is more challenging. The taxpayer’s dominant purpose must be making a profit. Importantly, the test applies at the commencement of the undertaking or scheme. The question is not whether profit eventually emerged. The question is whether profit was the main purpose when the project began. This requirement becomes highly fact-dependent. Contemporaneous documents, financing arrangements, correspondence, consultant reports, and taxpayer decisions may all become relevant in determining purpose.

• The Activity Must Exceed Mere Realisation

The third requirement is likely to be the primary battleground in future disputes. Inland Revenue accepts that section CB 3 does not tax the mere realisation of a capital asset. A taxpayer is generally entitled to dispose of an asset they own and obtain the best available price. The challenge lies in determining where ordinary sale preparation ends and a profit-making scheme begins.

Understanding “Mere Realisation”

The concept of mere realisation has generated substantial litigation over many years. In simple terms, if a taxpayer simply sells property they already own, that will often remain a non-taxable capital transaction. Even reasonable efforts to maximise sale proceeds do not necessarily change that conclusion. The draft interpretation statement provides several useful indicators.

Activities Likely to Be Mere Realisation

According to Inland Revenue, the following activities will often remain within the realm of mere realisation:

• Straightforward subdivisions involving limited works
• Minor council-required improvements
• Repainting or recarpeting before sale
• General cosmetic repairs
• Remediation of structural issues
• Re-cladding a leaky property

These steps are viewed as making an existing asset more marketable rather than creating something fundamentally different.

Activities Likely to Exceed Mere Realisation

The position changes when the work becomes transformative. Examples identified by Inland Revenue include:

• Extensive subdivisions involving substantial infrastructure
• Construction of one or more new dwellings
• Major redevelopment projects
• Significant extensions
• Full structural renovations
• Internal reconfiguration that substantially changes the property’s character

In these situations, Inland Revenue considers the taxpayer may have embarked on a separate profit-making venture rather than simply selling an existing investment. That distinction will become critically important.

Do the Existing Land Sale Exemptions Still Matter?

One of the obvious concerns arising from the draft is whether section CB 3 effectively undermines long-standing exemptions found in the land sale rules. Inland Revenue says it does not: The Commissioner argues the exclusions and exemptions focus on the nature and use of the property itself. Section CB 3, by contrast, focuses on the existence of a separate profit-making undertaking or scheme. Under this approach, the provisions are said to target different things. As a result, Inland Revenue expects that in many situations where an exemption applies, section CB 3 will also be irrelevant because the taxpayer is merely realising a capital asset. However, the draft identifies circumstances where that comfort may disappear.

The Family Home Example

Perhaps the most striking example involves a family home. Ordinarily, a family home receives significant protection under the land sale provisions. However, Inland Revenue suggests the analysis can change if the owner embarks on a substantial redevelopment project.

Imagine a homeowner demolishes their existing residence and constructs several townhouses with the intention of selling them for maximum profit. The original use of the property as a family home may be irrelevant. According to Inland Revenue, the development project itself may constitute a separate profit-making scheme.

If that view is correct, section CB 3 could potentially tax the resulting profits even though the family home exclusion would otherwise have applied. For many taxpayers, that will come as an unwelcome surprise.

The Draft Statement’s Worked Examples

The interpretation statement includes several practical examples which provide useful guidance on Inland Revenue’s thinking.

A builder who sells a home she has genuinely occupied as her principal residence does not trigger section CB 3. That outcome reflects a straightforward disposal of a personal asset. In contrast, a homeowner who subdivides their land and constructs a new dwelling for sale is treated differently. The construction activity creates something new and goes beyond mere realisation. Inland Revenue therefore considers section CB 3 capable of applying.

Another example involves a relatively simple subdivision into four lots with only minor works required by local authorities. Inland Revenue accepts this may remain a non-taxable capital realisation. However, if houses are subsequently built on those lots to maximise eventual sale proceeds, the analysis changes significantly. The construction activity becomes the key driver of the profit-making scheme.

The statement also contrasts two renovation scenarios:

1. A landlord who undertakes a comprehensive transformation involving extensions, additional bedrooms, major structural work, and substantial reconfiguration may fall within section CB
2. By comparison, a landlord who updates a property with a new kitchen, bathroom, paint, and carpet will generally remain outside the provision.

The distinction is consistent throughout the draft. The more transformative the activity becomes, the greater the likelihood Inland Revenue will see a separate profit-making venture.

Practical Implications for Investors

Several important lessons emerge from the draft interpretation statement.

1. Where a specific land sale provision clearly applies, that remains the primary taxing rule.
2. Taxpayers should resist assuming that a successful escape from the land sale provisions guarantees a non-taxable outcome. Section CB 3 may still need to be considered.
3. Projects involving new dwellings, substantial redevelopment, or major renovations deserve careful analysis.

These activities now appear to be Inland Revenue’s primary focus.

Finally, taxpayers should remember that if section CB 3 applies, deductions are generally available.

These may include:

• Market value of the property when the scheme commenced
• Construction and development costs
• Interest expenses
• Rates
• Insurance
• Certain legal fees

While deductions reduce exposure, they do not eliminate the risk of a significant taxable gain.

Final Thoughts

Inland Revenue’s draft interpretation statement represents a significant development in the taxation of property transactions. The Commissioner now takes the view that section CB 3 can tax certain land disposals independently of the specific land sale rules. For taxpayers undertaking straightforward sales, the practical impact may be limited. However, projects involving redevelopment, construction, major renovation, or extensive value-add activities deserve renewed attention.

The draft statement suggests that Inland Revenue is increasingly focused on whether a taxpayer has merely sold an asset or embarked on a separate profit-making venture. That distinction may become one of the most important questions in future property tax disputes. Whether section CB 3 remains a narrowly targeted provision or evolves into a broader fallback argument whenever the land sale rules fail remains to be seen. For many investors, that uncertainty will be the most concerning aspect of the proposal.
