Latest News About HMRC to tax cash in ISAs from 2027

The UK tax authority HMRC will impose a new charge when the rule begins in April 2027. Cash sitting inside stocks and shares ISAs will be subject to a 22% tax on any returns earned. The measure targets savers who keep cash in these tax‑free wrappers. It intends to stop the practice of using ISAs to shelter interest without investment risk. Existing cash balances will be subject to the charge from the start date. The change will affect new and existing accounts alike.
