AI summary

The Labour Party has proposed a new Capital Gains Tax (CGT), potentially starting 1 July 2027, if elected. This would introduce a 28% tax on profits from selling commercial and residential investment properties.

Key exemptions would include the family home, farms, and inheritances. This plan differs from the existing bright-line test, which only targets short-term residential sales.

Property owners are advised to await the election outcome before making changes and seek professional advice if the law passes.
