A decade of UK Budgets, a deadline approaching: Is your wealth plan ready for April 2027?

Author: Michelle Holgate, wealth manager

Over the past decade, successive UK Budgets have delivered more than 130 notable changes to personal finance rules, touching on tax, savings and pensions.¹ Each is well documented in isolation, but their cumulative effect across a decade is less frequently examined. Two of these changes stand out both for their scale and their impact: reforms to ISAs and to the inheritance tax (IHT) treatment of pensions, both taking effect from April 2027.

A decade of accumulated change – and a struggle to keep up

According to research commissioned by RBC Wealth Management in Sept. 2026,² only half of UK respondents (51%) follows Budget news closely, and engagement splits sharply by age. People aged 55 and over are more than twice as likely to follow the Budget as 18- to 29-year-olds (66% versus 33%). Yet even among the over-55s, only around a third (33%) say it’s easy to keep track of the wealth-planning changes that follow. Across the population as a whole, that figure falls to 22%, with a mere 2% describing the task as “very easy.”

Michelle Holgate, a wealth manager at RBC Wealth Management in the British Isles, sees this pattern regularly in her conversations with clients. “Over the past 10 years, we’ve seen a significant number of changes to the rules around tax, savings and pensions,” she says. “People may find it difficult to keep track of the detail, even those who follow the Budget closely.”

As Holgate puts it: “The challenge is that each change can have implications that are complex to work through, and the cumulative effect can take time to fully understand.”

Bridging awareness and confidence

The difficulty of keeping up is not an abstract problem – it has a deadline. Two of the most significant changes in a decade arrive on the same date: 6 April, 2027. The Cash ISA allowance is being reformed, and unused pension pots are being brought into the inheritance tax net for the first time. Together, they touch the two pillars most wealth plans rest on – savings and retirement – and they land precisely when people are least equipped to notice.

According to the RBC Wealth Management survey, only around a third (35%) of people are confident that their current decisions and wealth plans reflect the recent Budget changes relevant to them. Even among the over-55s, only around half (49%) feel confident. The gap between awareness and confidence is where planning matters most: knowing that change has occurred is not the same as knowing what to do about it. For higher earners managing pensions, investments and estate planning simultaneously, that gap is where the cost of inaction is greatest.

What follows are the two changes most likely to reshape plans before that deadline – and the evidence of how far awareness still has to travel.

Cash ISA reforms are coming in April 2027

Despite being one of the most prominent measures announced at the UK Budget 2025, awareness of the Cash ISA reforms remains limited. The RBC Wealth Management research found that only around half (53%) of people know the rules are changing, and of those who believe they are informed, only around two-fifths (43%) could correctly identify what is changing.

Even among those who are aware, 90% said they had no plans to review their approach in light of the new allowance split. Among ISA holders specifically, over 40% said they would not maximise their allowances before the changes take effect, and a further 10% said they would not contribute at all in 2026.

“The reduction to the Cash ISA tax-free allowance represents a potentially momentous shift in the UK savings and investment landscape,” Holgate says. “It’s strongly advisable to review your current ISA holdings and consider whether your assets are optimally positioned to meet your goals.”

From 6 April 2027, the annual Cash ISA limit will be reduced to £12,000 for those under 65, while the overall ISA allowance remains at £20,000. Those aged 65 and over will retain the higher £20,000 Cash ISA limit. The remaining £8,000 of the overall allowance can be used for Stocks and Shares ISAs or other ISA types. The reforms go further: interest on uninvested cash held in a Stocks and Shares ISA will face a 22% flat-rate charge, and transfers from Stocks and Shares ISAs into Cash ISAs will no longer be permitted for those under 65.

Understanding the upcoming new rules on pensions and inheritance tax

The second major change concerns pensions and inheritance tax. From 6 April 2027, most unused pension funds and death benefits will be brought within the scope of IHT, a measure first announced at the UK’s Autumn Budget 2024. For decades, pension pots have passed largely free of IHT. That is now about to change.

Awareness is even lower here. According to the RBC Wealth Management survey, just 30% of people know the IHT treatment of pensions is changing, and fewer than half (43%) of those approaching or in retirement recognise this. Of those, just over half (56%) could correctly identify what is changing. Taken together, only 17% of people are both aware of the change and able to correctly identify it.

Among those most directly affected, the response has been measurable. In a recent RBC Brewin Dolphin survey of 1,000 affluent UK individuals, over half (62%) said they were concerned about the upcoming inheritance tax changes, and just under a third (30%) had already adjusted their gifting in response.

The nil-rate band – the tax-free threshold below which an estate pays 0% IHT – has been frozen at £325,000 until April 2031, and the residence nil-rate band at £175,000 until the same date. With pension pots now joining the estate, the government estimates that around 10,500 estates will become newly liable for IHT in 2027/28, and a further 38,500 will pay more than before.³ A fuller examination of these reforms, including the treatment of death-in-service benefits and transferable allowances, is available here.

“The changes coming in April 2027 will significantly reshape how pensions are treated in estate planning,” Holgate says. “Bringing them into estate calculations, coupled with the freezing of the nil-rate band and the residence nil-rate band until 2031, means more people will find themselves caught in the inheritance tax net for the first time, possibly without realising it.”

Reviewing plans before April 2027

The window for reviewing plans is narrowing, but it is still open. For savers, it means thinking ahead about how to use the current £20,000 cash ISA allowance before April 2027. For investors, the 22% charge on uninvested cash in stocks and shares ISAs makes it worth reviewing how assets are allocated within existing ISA wrappers. For families, pension pots will now form part of the estate for deaths on or after 6 April 2027, making IHT planning a more pressing consideration than it has been for some time.

Gifting is one strategy that some affluent individuals are already pursuing. “If you’re in a position to do so, gifting while you’re alive can be one way to start planning around inheritance tax exposure, but it’s important to understand the rules and have the right advice,” Holgate says. Someone making a gift must live for at least seven years afterwards for it to be fully exempt from IHT.

“With significant changes to ISAs and to the inheritance tax treatment of pensions both taking effect from April 2027, now may be a good moment to review your plans and make sure they still reflect the current rules,” she says. “These are changes that can have a meaningful impact on long-term financial plans, and planning well ahead of time can make a real difference. While open discussions can be uncomfortable, an honest conversation with your loved ones before making any gifts can help you understand where passing on wealth through specific gifts will have the most impact.”

A decade of Budgets has shown that personal finance rules do not stand still, and the cost of not keeping pace is rarely felt immediately. The practical response is not to master every detail, but to recognise when the rules have shifted enough to warrant professional advice.
