Keep Your Hands Off Our Cash ISAs

By the Editorial Team · Wednesday, October 14, 2026

Chancellor John Healey is set to deliver his first Budget, facing calls to reconsider proposed cuts to the cash ISA allowance that would limit under-65s to £12,000 annually and introduce new taxes on certain ISA-held cash returns. Critics warn these changes could complicate the tax-free savings scheme, potentially reducing participation and offering limited economic benefits despite government intentions to boost investment in higher-yield assets.

As Chancellor John Healey prepares to unveil his first Budget in two weeks, financial experts and industry voices are urging him to reconsider a planned reduction in the cash Individual Savings Account (ISA) allowance introduced by his predecessor. The change would lower the annual cash ISA limit to £12,000 for savers under 65, a move critics argue could undermine the popularity and simplicity of the ISA product without delivering meaningful economic benefits.

The ISA scheme, a long-standing feature of the UK’s financial landscape, allows individuals to save or invest up to £20,000 annually free of income or capital gains tax. It is widely regarded as an accessible and straightforward way for more than 22 million adults to build savings or invest for the long term. Typically, account holders can spread their allowance across multiple ISA types, including cash ISAs, fixed-rate bonds, and stocks and shares ISAs, offering flexibility based on personal financial goals.

Beginning in April next year, the current proposal would prevent under-65s from freely distributing their allowance between cash and stocks and shares ISAs. Specifically, the cash ISA limit would be capped at £12,000, and transferring investments from a stocks and shares ISA into a cash ISA would no longer be permitted. Furthermore, cash held within stocks and shares ISAs would be subject to a flat 22 percent tax on returns, regardless of age or adherence to the new cash ISA limits. This tax amount would be automatically deducted by ISA providers and paid directly to HM Revenue and Customs (HMRC). Notably, savings accrued in cash-like investments—such as money market funds—held within non-cash ISAs would also attract taxation if they represent 100 percent of the account's holdings.

These adjustments mark a significant departure from the principle of tax-free savings within ISAs and are expected to introduce additional administrative challenges for both providers and regulators. ISA providers face an estimated £6 million in implementation costs due to the necessary regulatory and IT system changes. HMRC must also allocate resources to enforce these new rules amid ongoing pressures on its operational capacity.

Supporters of the reforms argue they aim to encourage greater investment into the UK economy by steering savers away from cash holdings, which typically generate lower returns, toward higher-yielding assets. However, evidence from HMRC’s own recent analysis suggests that the changes are unlikely to produce a significant macroeconomic impact. Moreover, feedback from the financial industry and consumer advocates highlights concerns that the added complexity and taxation could deter savers from investing altogether, potentially leading to decreased participation in ISA schemes.

As the Budget approaches, Chancellor Healey faces pressure to either uphold the planned reforms or revisit the policy to preserve the ISA’s current flexibility and appeal, maintaining its status as a cornerstone of UK personal finance.
