Capital gains tax reform announced for 1 July 2027
Treasury has announced a change to the way certain capital gains will be taxed. The detail matters for investors, families and business owners planning a disposal.
What has been announced
The Government says the current 50% CGT discount will be replaced by a discount based on inflation, alongside a minimum 30% tax rate on capital gains. Treasury says the new arrangements will apply to gains accruing from 1 July 2027 when realised. It has also outlined a choice of treatment for investors in new builds.
What clients should review
Keep reliable acquisition, improvement and disposal records, and distinguish gains accrued before and after the proposed start date. Asset type, ownership structure, timing and access to other concessions can affect the result. Do not assume that a published headline rate determines the tax on your transaction.
What remains open
These are announced policy measures. The final enacted law, transitional mechanics and application to particular structures should be checked before a transaction or restructuring decision. Treasury has separately consulted on arrangements for innovative start-ups.
