Targeted capital gains tax on property

In depth — from Labour’s policy document

Labour proposes a 28 percent tax on the profit made when a commercial or residential property is sold, excluding the family home. It applies only to gains made after 1 July 2027 — any increase in value before that date is not taxed — and is generally paid at the point of sale. The party says all revenue would be ring-fenced for health, funding three free GP visits a year for everyone.

How it would work

Valuation day sets the starting point

Commercial and residential properties other than the family home are given an opening value at 1 July 2027. Only the gain above that value can be taxed, so nothing earned before that date is captured. The document says several valuation options would be available, following the 2019 Tax Working Group’s recommendations, but does not settle on one.

How the gain is worked out

The taxable gain is the sale price, minus the purchase price (or the 1 July 2027 valuation where that applies), minus eligible costs. The cost of capital improvements is deducted, with what the document calls clear requirements to show the work was done.

  • Purchase costs are deductible at the time of sale
  • Capital improvements are deducted from sale proceeds
  • Holding costs such as rates and interest are not deductible, following the Tax Working Group
Taxed per person, not per property

The tax applies at the individual level, so each owner is taxed on their share of a gain. The document’s example: two business partners each owning half an investment property sold for a $100,000 net gain would each pay 28 percent on their own $50,000.

Transfers that do not trigger the tax

The tax is generally paid on sale, but not where ownership does not substantively change. Transfers to a spouse, civil union partner or de facto partner are not taxed, nor are transfers arising from a relationship ending or from death. If the property is later sold and is taxable, the gain is measured only from 1 July 2027.

Losses can be carried forward, but only against like assets

Selling a covered property for less than its cost, including improvements, creates a capital loss. That loss can be carried forward against future capital gains, but it is ring-fenced — it cannot be set against salary or other income.

Death is not a taxing point

An inheritance is not treated as a realisation event, so no tax is triggered when someone dies. The document lists inheritances among the exemptions.

Worked examples

These scenarios and figures are Labour’s own, from the document.

A rental and a business, sold on retirement
The situation
  • Daniel owns his family home, a rental property, and all the shares in his laundromat business
  • He bought the rental for $650,000; on valuation day it was worth $700,000
  • On valuation day the laundromat was valued at $1,100,000, of which the building was $800,000
  • He buys new machines, and the business grows to $1,400,000
What happens
  • The family home is excluded, so it is not taxed
  • The rental sells for $750,000 — tax applies only to the $50,000 gain since valuation day
  • On the business sale, the building’s value must be separated from the business’s
  • Only the part of the price reflecting the rise in the commercial property is taxed — not gains from the business itself or the new equipment
A family home and a holiday home, passing through an estate
The situation
  • Phyllis and Liam own their Wellington family home, valued at $900,000
  • They also own a Northland holiday home valued at $600,000, in both their names
What happens
  • When Liam dies, his share transfers to Phyllis with no tax to pay
  • When Phyllis dies, the five children cannot agree how to split the assets and decide to sell both
  • Inheritances are exempt, so no tax is due when the assets transfer to the executor
  • Both are sold within six months — the family home for $1,100,000 and the holiday home for $650,000
  • The children split $1,750,000 with no tax to pay

Labour’s own forecast, using the model developed by the 2019 Tax Working Group with an updated asset base and assumptions. It is not a Treasury costing.

In their own words

“There will be a 28 percent tax on any profit made after 1 July 2027 when a commercial or residential property (excluding the family home) is sold. Not a single dollar of profit made before 1 July 2027 will be taxed.”

“Every dollar raised will be ring-fenced to provide all New Zealanders with better healthcare, starting with three free doctor’s visits each year for all New Zealanders.”

Targeted tax changes to grow the economy and invest in health · How it works — where the money goes

“Losses are ring-fenced, so they can only be used to offset gains from the same type of asset, not against salary or other income.”

What the document doesn’t settle

Points the document defers or leaves undefined. These are gaps in the document, not criticisms of the policy.

  • The document does not define “family home”, so how the exemption applies to mixed-use or multi-dwelling properties is not set out.
  • The valuation method is not fixed — it says different options will be available, in line with the Tax Working Group’s recommendations.
  • Everything not covered in the document is deferred: it states that all other tax technical details will follow the 2019 Tax Working Group’s recommendations.
  • The revenue figures are the party’s projection from a 2019 model with updated assumptions, not an independent costing.
