Millions face ISA savings squeeze as £12,000 cash cap looms, finance expert warns

With the new tax year fast approaching on 6 April, savers are being urged to review their ISA strategy ahead of significant changes to cash allowances. According to Shepherds Friendly, the 2026/27 tax year represents the final opportunity to take full advantage of the current cash ISA limit before a £12,000 cap is introduced from April 2027.

Derence Lee, Chief Finance Officer at Shepherds Friendly, comments on what this means for savers and how they can make the most of this final year before the cap takes effect:

“The new tax year begins on 6 April, giving savers and investors a fresh opportunity to make full use of their annual allowances. For the 2026/27 tax year, this is the last year individuals can contribute their full annual allowance into a cash ISA. From the 2027/28 tax year onwards, the amount that can be held in a cash ISA will be capped at £12,000, meaning those wishing to use their full ISA allowance may wish to direct the remaining portion into a stocks and shares ISA.

“While cash ISAs remain important for short-term savings and emergency funds, stocks and shares ISAs could be better suited to those looking to grow their investments over the medium to long term, offering access to a wide range of funds to suit different goals, risk appetites and budgets. 

“Despite this, our data shows that 48% of people aren’t confident when it comes to investing, and only one in ten savers currently hold a stocks and shares ISA. Education and research can help bridge this confidence gap, showing the real-life benefits of stocks and shares ISAs compared to cash ISAs beyond just tax efficiency, such as the potential for your money to grow more over time to help achieve your financial goals. 

“As the cash ISA limit drops from 2027/28, reviewing your allocations now and taking the time to understand stocks and shares ISAs can help you make full use of your ISA allowance and plan the right mix of cash and investments ahead of the changes coming into effect next year.”

“Taking action sooner rather than later can help ensure you make full use of your ISA allowance, benefit from potential tax-free growth and get your long-term financial goals on track. However, investments should be considered in the context of your overall financial situation and risk tolerance.”
