Indexation for older assets
The cost of an asset acquired before 2003 is uplifted by Revenue's official multiplier for the year of purchase, so inflation isn't taxed as gain. Indexation is frozen, costs from 2003 onward get no uplift.
Reliefs and rates
Standard CGT is 31% on disposals from 7 October 2026 (it was 33% before). Entrepreneur Relief gives 10% on qualifying business gains up to a €1.5m lifetime cap; Principal Private Residence relief exempts the main-home proportion. Each person also has a €1,270 exemption a year, shared across all their disposals that year, and it can't be passed to a spouse or civil partner. This calculator applies it in full to the one sale you enter.
