Autumn Budget 2026: Healey scraps planned ISA shake-up

In what has been a less “leaky” Budget than previous ones, today we had some clarity on the proposed cash ISA changes, with Chancellor John Healey announcing that the previous governments’ proposals will be scrapped and the full £20,000 cash individual savings allowance (ISA) will be retained in order to “support savers”.

However, the government also said it “recognises the importance of making investment more accessible to savers, supporting households to build their wealth”, and that they will “work with the investment industry to explore a new ISA incentive for people investing in a stocks & shares ISA for the first time.” Adding that “the detailed design will be developed with industry” – raising further questions.

What has been scrapped?

Last Autumn, Rachel Reeves announced that from April 2027 those aged under 65 would be limited to putting £12,000 into a cash ISA, in a bid to nudge more money out of savings accounts and into the stock market. With that, however, came a range of complexities and questions - particularly around how this would actually work in practice, and whether this truly reflects what’s needed.

Examples of this included the implementation of anti-circumvention measures such as restricting transfers from non-cash ISAs into cash ISAs, and imposing a 22% tax charge on interest earned on uninvested cash held within stocks & shares ISAs. This risked penalising savers unfairly; after all, cash held within a stocks & shares ISA is often just part of the investment journey, whether someone is gradually investing their money, receiving dividends, or rebalancing their portfolio. And it’s the flexibility to do these very things that is why ISAs are such powerful tools for people.

There was also initial uncertainty around where money market funds - which continue to pique investor interest - fit within the ISA puzzle, with concerns over whether investors could have used these as a cash-like substitute to curb the new rules, and subsequent confusion on whether these would have faced that same 22% charge.

It was then later confirmed that investors would have been able to hold money market funds within their stocks & shares ISAs, as long as they didn’t make up 100% of their portfolio. In reality though, as we know from our quarterly ii Index, investors understand the role that money market funds can play within a much broader and diversified ISA portfolio. They’re not putting all their eggs in one basket.

Whether the anti-circumvention measures will also be scrapped is unclear given their absence from the speech and the Budget red pages. But the smart money suggests they will be.

Why today’s U-turn on the cash limit is a welcome exception for savers and investors

The sum of these various moving parts was just further complexity. And although today’s announcement marks another policy U-turn at a time where we need more consistency for savers and investors, the scrapping of the changes to cash ISAs is a welcome exception.

The previously proposed changes would just have added layers of unhelpful difficulty to an already overly saturated ISA market which we know many people struggle to navigate as it is.

Now what?

In what financial commentator Martin Lewis has called a “carrot, not a stick approach,” the government has announced plans for new ISA incentives for those starting out with investing. At the time of writing, it’s very unclear whether this means there will be a creation of a new “Starter” ISA, or whether the aim is to create better incentives within existing stocks & shares ISAs. The detail will be ironed out in the consultation process, but again – regardless of the admirable ambition behind this, it strays into further overcomplication.

Research from The Investment Association (IA) earlier this year showed that 53% of investors already think the ISA market is becoming too complicated. More broadly, the IA’s ISA Barometer report uncovered that although people have heard of ISAs, many are less confident about how they work and which is most suited to their goals. This gap between ISA awareness and meaningful understanding is especially clear for stocks & shares ISAs, where awareness stands at 86% but self-assessed knowledge at just 36%.

What’s really going to move the dial

Ultimately, there are more nuanced reasons why cash savers are not investing in the markets. Changing the cash ISA limit, alone, was never going to be enough to move the dial in creating a nation of investors.

Research consistently proves that a core barrier to investing in the markets is consumer perception of inherent risk; something the industry is looking to tackle with a review of how we communicate investment risk to consumers, and whether we – as an industry - can better reflect long-term risk and reward with investing. 

Plus, the hesitancy to invest is a natural spillover from a lack of financial education on the long-term power and importance of investing, and how both saving and investing can play important – but different – roles in your financial toolkit. A topic which is still something we write about regularly.

Getting this right would go a long way in creating more long-term incentives for investing, without the need for complicating ISAs further.

We also have to appreciate the ongoing inflationary pressures, the increased cost of living, and the various squeezes on our personal finances – meaning that short-term saving becomes more attractive as a flexible buffer, and long-term financial goals can naturally take a backseat.

The government’s ambition to drive more retail investment is a very important one that we fully support, but we believe that reforms need to reflect how people actually invest and make the journey feel simpler and therefore more rewarding. Helping people feel informed and confident enough to get started is likely to have a far greater impact than asking them to navigate ever more complex rules. Only time will tell what happens with what’s been announced today on ISAs, but hopefully we’ll avoid another stark about-face and instead have some much need consistency and simplicity.
