Tax Reform Scenario
Purchase date
Property type
Assumed CPI / year
%
July 2027 reforms are modelled as an indicative scenario based on announced measures. For established properties bought after 12 May 2026, rental losses from July 2027 are carried forward. Post-June 2027 capital growth uses assumed CPI indexation and a 30% minimum tax on real gains. Confirm enacted rules and transaction dates before relying on after-tax returns.
