UK Parliament has published the Government’s response to the Treasury Committee’s report on the Cash ISA, setting out the Government’s rationale for the Chancellor’s planned reform to reduce the tax-free Cash ISA allowance to GBP 12,000 for people aged under 65 from 6 April 2027. The response, signed by the Economic Secretary to the Treasury Lucy Rigby MP, frames the change as part of the Government’s plans to encourage savers to invest, with the stated aim of enabling higher returns and longer-term financial resilience. The Committee’s October report had warned that cutting the Cash ISA allowance was unlikely to incentivise people to invest savings in stocks and shares; the Treasury Committee Chair, Dame Meg Hillier, reiterated concerns that the reforms could complicate the ISA landscape and confuse consumers, while noting that attention now turns to how the revised product will be delivered in practice.
