The UK government published the policy paper “Reduction in the cash Individual Savings Account (ISA) limit” on 17 September 2026, confirming a significant change to the tax-free savings landscape. The paper proposes reducing the annual cash ISA subscription limit from £20,000 to £10,000, effective from the 2027/28 tax year. The overall ISA annual subscription limit remains at £20,000, but the cash component is capped, with the remainder available for stocks and shares ISAs, innovative finance ISAs, and lifetime ISAs. The reform aims to encourage longer-term investment and redirect savings toward productive capital markets, aligning with the government’s capital markets reform agenda.
Key Takeaways
- New Cash ISA Cap and Transitional Rules: From 6 April 2027, individuals may subscribe up to £10,000 per tax year into cash ISAs. Existing cash ISA balances are unaffected and retain tax-free status. Savers can still hold multiple cash ISAs but total new subscriptions across all cash ISAs cannot exceed the new limit. The government will consult on whether to allow unused cash ISA allowance to be carried forward.
- Impact on Savers and Financial Institutions: The change primarily affects risk-averse savers who utilise the full £20,000 cash ISA allowance. Banks and building societies must update systems, marketing, and product offerings ahead of the 2027/28 tax year. HMRC will amend ISA regulations and reporting requirements for ISA managers, with draft legislation expected in Finance Bill 2027.
- Strategic Shift Toward Investment: The policy signals a clear governmental preference for equity and bond investment over cash holdings. Advisers should review client portfolios to optimise the new allowance structure, considering stocks and shares ISAs for the remaining £10,000. The paper also hints at future simplifications, such as a single ISA wrapper, which could further reshape the tax-advantaged savings market.
