HM Revenue and Customs (HMRC) says it plans to introduce a 22% charge intended to stop some ISA savers from working around new rules that are due to begin in 2027. HMRC states that the charge is designed to help ensure the ISA policy meets its intended objectives rather than being avoided through alternative arrangements. The reported proposal sets out that “several rules” will also be introduced alongside the charge, indicating HMRC plans a package of measures rather than a single change. According to HMRC, these additional rules are meant to address ways savers could otherwise restructure their savings or transfers to achieve effects that the reforms aim to prevent. The sources provided do not specify the full details of the new ISA rules themselves, or how the charge would apply in different scenarios. They also do not indicate the precise mechanism for calculating the 22% charge, which ISA products or investor circumstances it would cover, or the timing of any consultation or legislative steps.
