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 33%. 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 disposal also gets a €1,270 annual exemption.
Editable, verified rates
The rates and the full multiplier table are sourced from revenue.ie and stored so they can be updated after each Budget without a redeploy. Estimates only, reliefs like retirement relief and share-matching rules aren't modelled.
