Launch of HMRC’s CGT interactive calculator for 2024/25 tax returns

20 Mar 2025

Following changes to the CGT rates from 30 October 2024, HMRC has now launched the final version of their CGT calculator.

As the 2024/25 self-assessment tax return has not been configured to the new rates for the year, this calculator is designed to help taxpayers manually adjust their total CGT liability accordingly.
