The United Kingdom is poised to implement significant changes to its Individual Savings Account (Isa) rules, which will restrict the amount individuals under 65 can save tax-free in cash Isas. The annual allowance for cash Isas is set to decrease from £20,000 to £12,000 starting in April.
The overall Isa limit, encompassing both cash and stocks and shares accounts, will remain at £20,000. This means any savings beyond the new £12,000 cash Isa limit must be directed into a stocks and shares Isa to utilize the full £20,000 allowance.
These changes are a continuation of measures introduced by former Chancellor Rachel Reeves in the Autumn Budget 2025. The Treasury has indicated that the final details of the new rules will be published in the autumn, with industry insiders anticipating their release as early as next month, well before the new Chancellor John Healey's first budget on October 28.
Furthermore, individuals under 65 will no longer be permitted to transfer money from a stocks and shares Isa into a cash Isa. This restriction is intended to prevent savers from moving funds between Isa types to maximize tax-free interest. Additionally, any cash held within a stocks and shares Isa will be subject to a 22% tax on interest earned, regardless of the saver's age.
For savers aged 65 and over, the annual cash Isa allowance will remain at £20,000. This higher allowance becomes effective from the start of the tax year in which the individual turns 65.
In light of these upcoming changes, experts are advising savers to maximize their current tax-free cash Isa allowance before the new rules take effect. The article highlights several top-rate cash Isa options, including an easy-access flexible Isa from Trading 212 offering 4.6% interest, with a one-year bonus. Coventry Building Society offers a 4.25% rate on its 4 Access Isa, which is flexible but limited to four withdrawals annually. For those seeking a simple, non-flexible account, Hargreaves Lansdown provides 4.52% interest, while Spring offers 4.01% on a flexible Isa without bonus or withdrawal restrictions. Fixed-rate options include Vida, with rates up to 4.85% on a five-year fix.
The Building Societies Association has noted that the new Chancellor faces a decision on whether to proceed with the proposed changes or to scrap them. However, given that the changes are a significant revenue generator, they are unlikely to be rescinded.
Savers are encouraged to take advantage of the current allowance and explore the best available rates, ensuring accounts are covered by the Financial Services Compensation Scheme up to £120,000.
