Capital Gains Tax NZ 2026: What Labour’s Proposal Could Mean for Business Owners

Last updated: August 2026

New Zealand’s capital gains tax debate has returned to the spotlight, with Labour proposing a targeted 28% capital gains tax on certain property profits from 1 July 2027 if it forms the next government.

For New Zealand business owners, property investors and people considering buying or selling assets, the proposal raises an important question:

What could a capital gains tax mean for your business and investment decisions?

The answer depends heavily on what asset you own, when the gain arises, and whether Labour’s proposed policy becomes law in its current form.

It is important to clarify that New Zealand does not currently have a broad-based capital gains tax. New Zealand already taxes certain capital gains in specific circumstances under existing tax rules, but Labour’s 2026 election policy proposes a new targeted tax on certain commercial and residential investment property gains.

In this guide, DFK Orb360 O’Halloran Chartered Accountants explains what Labour has proposed, what assets would be affected, what would be excluded, and what business owners should consider before making major investment or property decisions.

Quick Answer: Is There a Capital Gains Tax in New Zealand?

New Zealand does not currently have a comprehensive capital gains tax covering all capital assets.

However, certain gains can already be taxable under existing tax rules. For example, some property transactions may be taxable depending on the circumstances and the rules applying to the transaction.

Labour has proposed introducing a targeted 28% capital gains tax on profits made after 1 July 2027 when certain commercial or residential investment property is sold. The proposal excludes the family home, farms, KiwiSaver, shares, businesses, inheritances and personal items.

The proposal is not currently law. Its implementation would depend on the outcome of the 2026 general election and subsequent legislative action.

What Is Capital Gains Tax?

A capital gains tax (CGT) is a tax on the profit or gain realised when certain assets increase in value and are sold or otherwise disposed of.

For example, if an asset is purchased for $500,000 and later sold for $700,000, the difference may represent a $200,000 gain.

However, whether that gain is taxable depends on the tax rules applying to the particular asset and transaction.

This is why the question “Is there a capital gains tax in NZ?” does not have a simple yes-or-no answer.

New Zealand’s existing tax system already taxes some gains under specific provisions, while other capital gains are generally not taxed simply because an asset increased in value.

Understanding the distinction between existing tax rules and a proposed capital gains tax is important when making business or investment decisions.

What Is Labour’s Proposed Capital Gains Tax?

Labour’s 2026 election policy proposes a targeted 28% tax on profits from the sale of commercial property and residential investment property, excluding the family home and farms.

Under Labour’s published proposal:

• The proposed tax rate is 28%.
• It would apply to profits made after 1 July 2027.
• The tax would apply when the relevant property is sold.
• The family home would be excluded.
• Farms would be excluded.
• KiwiSaver would be excluded.
• Shares would be excluded.
• Businesses would be excluded.
• Inheritances would be excluded.
• Personal items such as cars, boats, art and furniture would be excluded.

Labour says the policy is intended to redirect investment away from property speculation and towards productive investment, while using the revenue to fund health initiatives.

Is Labour’s Capital Gains Tax Law Yet?

No.

This is one of the most important points for anyone searching for capital gains tax NZ 2026.

Labour’s capital gains tax is currently an election policy proposal, not an enacted tax.

Labour’s published policy states that the proposed tax would start from 1 July 2027, but that does not mean the tax is already part of New Zealand law. The policy would need to proceed through the legislative process if Labour were to form a government and implement it.

Therefore, business owners should not assume that the proposed 28% tax currently applies to their property transactions.

At the same time, businesses considering significant transactions should not ignore the proposal. Major property purchases, restructures and sales can have long-term financial consequences, making professional tax advice particularly valuable.

What Assets Would Labour’s Proposed Capital Gains Tax Cover?

Under Labour’s current published policy, the proposed tax would focus on commercial property and residential investment property.

This could potentially include investment properties and commercial property where the relevant conditions are met.

The proposal is specifically described as applying to the profit made after 1 July 2027 when the property is sold.

Example

Labour provides an example involving a commercial property purchased for $400,000.

If the property is valued at $600,000 on 1 July 2027 and later sold for $700,000, Labour’s policy says the proposed tax would apply to the $100,000 gain arising after 1 July 2027, rather than the increase in value before that date.

This illustrates why the proposed 1 July 2027 valuation point could become important if the policy is implemented.

What Would Be Exempt From Labour’s Proposed CGT?

Labour’s current policy specifically lists several categories that would be excluded.

Family Home

The family home would not be subject to the proposed tax.

Farms

Labour’s policy says farms would be exempt.

Shares

The proposal would not apply to gains from shares.

KiwiSaver

KiwiSaver would be excluded.

Businesses

Labour states that the tax would not apply to businesses themselves.

Inheritances

Inherited assets would be excluded under the published proposal.

Personal Items

Personal items such as cars, boats, art and furniture would also be excluded.

This means that simply describing the proposal as a “tax on all capital gains” would be inaccurate. It is much more specific than that.

What Could Labour’s Proposed Capital Gains Tax Mean for Business Owners?

For business owners, the potential impact of capital gains tax NZ rules will depend largely on the type of asset being sold and how that asset is held.

Labour’s current proposal specifically targets profits from the sale of certain commercial and residential investment property. It does not propose a broad tax on the sale of businesses themselves.

However, business owners who own property alongside their operating business may need to consider how any future rules could affect their investment and long-term planning.

For example, a business may own:

• A commercial building.
• A warehouse or industrial property.
• Residential investment property.
• Property held separately from its operating business.
• Other investment assets.

The tax treatment of each asset can depend on its ownership structure, use, acquisition date, disposal date and the legislation applying at the time of sale.

This is why business owners should avoid making major decisions based solely on headlines about Labour’s capital gains tax proposal.

How Could the 1 July 2027 Date Matter?

One of the most important details in Labour’s proposal is the proposed 1 July 2027 start date.

Under the policy, the proposed tax would apply to gains arising after this date on affected property.

Labour’s published example illustrates a potential valuation approach. If a commercial property is worth $600,000 on 1 July 2027 and is subsequently sold for $700,000, the proposed tax would apply to the $100,000 increase occurring after the proposed valuation date.

This means that, if the policy becomes law, establishing the value of affected property around the proposed commencement date could become an important consideration.

However, the exact valuation, record-keeping and transitional requirements would ultimately depend on the legislation enacted.

Business owners should therefore keep appropriate acquisition, valuation and improvement records for significant assets and seek professional advice before making decisions based on the proposed rules.

Example: How Could a 28% Capital Gains Tax Work?

Consider a simplified example of an investment property that falls within the proposed rules.

Suppose an affected property has a relevant value of $800,000 at the applicable commencement point and is later sold for $1 million.

The increase in value would be:

$1,000,000 − $800,000 = $200,000

If the entire $200,000 gain were taxable at a 28% rate under the final legislation, the indicative tax would be:

$200,000 × 28% = $56,000

This is a simplified illustration only. It should not be treated as a calculation of the tax that would actually be payable because the final rules, allowable costs, valuation methodology, ownership arrangements and other provisions would need to be considered.

Could Capital Gains Tax Affect a Business Sale?

One of the most important questions business owners ask is whether they would pay capital gains tax when selling their business.

Under Labour’s current published policy, the proposed capital gains tax would not apply to businesses themselves.

However, a business sale can involve multiple assets and transactions, including property, shares, goodwill, intellectual property and other business assets.

The tax treatment of these components can depend on the structure of the transaction and the applicable tax rules.

If you’re planning to sell a business, it is therefore important to obtain professional tax and accounting advice before agreeing to the transaction.

Early advice can help you understand the potential tax consequences and evaluate different transaction structures.

Capital Gains Tax NZ vs the Bright-Line Property Rule

Capital gains tax and the bright-line property rules should not be treated as the same thing.

New Zealand already has rules that can tax certain residential property gains when property is sold within the applicable bright-line period, subject to the relevant rules and exclusions.

A proposed capital gains tax would represent a different policy approach and should be considered separately from the existing bright-line rules.

This distinction is important because searching for capital gains tax NZ does not necessarily mean that every property gain is currently subject to a capital gains tax.

The tax treatment depends on the circumstances of the transaction and the rules that apply to the asset.

What Should Property Investors Consider?

Property investors should pay close attention to the details of any proposed changes rather than relying on general statements about a capital gains tax.

Important questions may include:

• What type of property is being held?
• Is it a residential investment property or commercial property?
• When was it acquired?
• How is it owned?
• What is its current market value?
• What records exist to establish its acquisition cost and improvements?
• When might the property be sold?
• Would the transaction fall within existing tax rules?
• Would any future legislation apply to the property?

These questions can become particularly important for investors holding multiple properties or businesses with significant property assets.

Should You Sell Property Before 1 July 2027?

Not necessarily.

The proposed 1 July 2027 date may encourage some property owners to consider whether they should sell before the proposed commencement date.

However, making a major investment decision solely to avoid a proposed future tax can create other financial consequences.

Selling property may involve transaction costs, financing considerations, market conditions, business requirements and existing tax obligations.

There is also no guarantee that a proposed policy will become law exactly as currently published.

Before deciding whether to sell, hold, restructure or acquire property, business owners should consider the complete financial picture rather than focusing on one potential tax cost.

How Can Business Owners Prepare for Potential Tax Changes?

Even though Labour’s proposed capital gains tax NZ policy is not currently law, businesses can take sensible steps to improve their financial records and decision-making.

1. Maintain Accurate Asset Records

Keep records showing purchase prices, acquisition dates, improvements, ownership structures and other relevant costs associated with significant assets.

2. Review Property Holdings

Business owners with commercial or residential investment property should understand how those assets are currently held and used.

3. Understand Existing Tax Obligations

Do not wait for proposed legislation to understand the tax rules that already apply to your property or business transactions.

4. Review Major Transactions Before Committing

If you’re considering purchasing, selling or restructuring a significant asset, obtain tax advice before signing an agreement where possible.

5. Monitor Policy Developments

Election policies can change and proposed legislation can be amended during the legislative process. Business owners should rely on the final legislation and official guidance rather than assuming that current policy proposals will automatically become law.

Why Professional Tax Advice Matters

Tax policy changes can create uncertainty for business owners, particularly when significant property or investment decisions are involved.

A professional tax advisor can help you distinguish between:

• Tax rules that currently apply.
• Proposed tax policy.
• Potential future legislation.
• Tax planning opportunities.
• Risks associated with major financial decisions.

What Should Business Owners Do Now?

There is no need for businesses to react to a proposed capital gains tax as though it is already law.

Instead, business owners should:

• Monitor the development of the proposed policy.
• Keep detailed records for significant assets.
• Review existing property and business structures.
• Understand the tax rules currently applying to their transactions.
• Consider the potential impact of future policy on long-term plans.
• Seek professional advice before making major decisions.

The most important point is simple: do not make an irreversible financial decision based solely on a proposed tax policy.
