AI summary

A Capital Gains Tax (CGT) is a key topic for property owners. New Zealand already has a quasi-CGT called the bright-line test, which taxes gains on residential properties sold within a set timeframe.

The Labour Party has proposed a new CGT if elected in 2026, starting 1 July 2027. It would feature:

- A 28% tax on gains from investment and commercial properties.

- Exemptions for the family home, farms, and KiwiSaver.

Owners would need a valuation on the start date. Property owners are advised to await the election outcome before making decisions.
