It’s already clear that Chancellor of the Exchequer Rachel Reeves is firmly focused on encouraging more Cash ISA savers to begin investing, but what does the new 22% levy on cash earnings within Stocks and Shares ISAs mean for account holders?
With Cash ISA allowances set to fall to £12,000 from £20,000 starting on the 6th of April 2027, major reforms to how we save money are already underway. It now appears that Reeves is set to shore up rules on Stocks and Shares ISAs to ensure that the money subscribed will be exclusively used for investment purposes.
Starting next year, a 22% tax will be introduced on interest gained on cash held within Stocks and Shares ISAs. But what exactly does this new levy mean for the millions of UK residents who hold individual savings accounts? Let’s take a deeper look at the new rules and how they may affect your money:
What is the New 22% Tax?
From April 2027, as the tax-free annual allowance for Cash ISAs is cut to £12,000, the chancellor will implement a 22% tax that will apply to interest on cash held in Stocks and Shares ISAs.
The move intends to close a loophole where some savers may look to retain their full £20,000 cash allowance by earning interest on money in a Stocks and Shares ISA.
Unlike their savings-focused counterpart, Stocks and Shares ISA limits will not be cut next year, and because some providers currently offer interest that can be earned on cash that isn’t invested, some Cash ISA holders had hoped to continue saving via the loophole.
Instead, Reeves has brought in the tax measure to discourage using Stocks and Shares ISAs as if they were Cash ISAs, ensuring that the former are used solely for buying and holding investments.
It’s estimated that the 22% levy will generate around £100 million in revenue for the economy, while ensuring that more savers begin investing to continue making the most of their £20,000 ISA allowance.
What Should Cash ISA Savers Do?
The most recent available government data shows that there were almost 10 million Cash ISA subscribers in the United Kingdom in the 2023/24 tax year, and the upcoming allowance cut is likely to disrupt many savings strategies for individuals of all ages.
Particularly if you’re one of the three-in-five UK savers who believe that investing is too risky, next year’s limitations to Cash ISA contributions could be particularly concerning, but there are some ways to navigate the 22% tax and allowance cut to tax-free cash savings.
Firstly, it’s important to know whether the Cash ISA cuts are actually going to impact your ability to save. Some savers who have already reached retirement age aren’t aware that there’s an over-65 exemption to the new £12,000 allowance, meaning that you’ll still be able to save to the full £20,000 limit if you’re 65 or older.
It’s also worth noting that ISA allowances are flexible and that you can still save £12,000 and use another £8,000 to add to a Stocks and Shares ISA as a way of maximising your tax efficiency.
Although many UK savers believe that investing is risky, data over the past 10 years shows that Stocks and Shares ISAs have delivered an average annual return of 9.64% compared to the 1.21% returns for Cash ISAs.
There are also plenty of relatively low-risk investments that can be made if you don’t have a high risk tolerance, such as dividend-paying stocks that generate a reliable passive income while remaining more resilient against market fluctuations.
You can also save more than £12,000 in cash on a tax-free basis by making the most of your personal savings allowance (PSA), which allows you to earn up to £1,000 in interest tax-free outside of traditional individual savings accounts.
Alternatively, you may find premium bonds to be a useful option to potentially grow your wealth in a tax-efficient way. It’s possible to invest up to £50,000 in premium bonds via NS&I, and you can win prizes that are paid out completely tax-free. Although profit isn’t guaranteed, your bonds can serve as a useful store of wealth.
Preparing for Cash ISA Limits
Although it’s becoming increasingly difficult to sidestep the upcoming limitations to Cash ISA savings, the millions of UK savers who are wary of the risks associated with investing can take a number of alternative approaches to maintain a level of tax efficiency while growing their wealth.
If you have a low risk tolerance, it doesn’t mean that investing isn’t for you, and there are plenty of different strategies you can adopt that are far less volatile than most speculative stocks.
Ultimately, you should find a strategy that not only complements your financial goals but also helps you to feel more comfortable about how your money is being put to good use. In avoiding the new 22% tax on cash interest in Stocks and Shares ISAs, you may discover a new approach that can help to improve your profitability over the long-term.
