The UK's inheritance tax landscape is about to get a lot more expensive for many families, with a perfect storm brewing on the horizon. But is it fair, or are the rules changing too much, too fast?
HMRC's Inheritance Tax Windfall: The UK's tax authority, HMRC, is projected to collect an additional £700 million in inheritance tax over the next few years, according to the Office for Budget Responsibility (OBR). This substantial increase is a result of two significant factors.
First, the OBR's latest figures reveal that the Treasury's inheritance tax revenue is expected to reach £70.6 billion between 2025/26 and 2030/31, a £700 million jump from the Autumn Budget 2025 forecast. And this is the part most people miss: the inclusion of pension pots in inheritance tax calculations from April 2027, as announced by Chancellor Rachel Reeves in her 2024 Budget.
Pension Pots and Tax Exposure: Previously, pensions were a tax-efficient way to pass on wealth, but the new rules will expose more estates to the 40% inheritance tax levy. This change is set to impact tens of thousands of families who have relied on pensions as a tax-saving strategy.
But here's where it gets controversial. The OBR predicts that by 2030/31, more than 16,000 estates will be valued at over £2 million, primarily due to frozen tax thresholds and rising property prices. This means that inheritance tax is no longer just a concern for the ultra-rich; it's increasingly affecting middle-income households, too.
The Impact on Middle-Income Families: Emma Walker, a director at Just Group, highlights the growing burden on these families. "The OBR's forecasts show how inheritance tax is becoming a cash cow for the Treasury, with an additional £0.7 billion expected over the next five years." Annual receipts are projected to soar from £8.7 billion this year to a staggering £14.7 billion by 2030/31.
A Little-Known Tax Trap: One aspect that catches many families off guard is the residence nil rate band. This additional allowance of £175,000 is gradually reduced by £1 for every £2 that an estate exceeds the £2 million threshold, disappearing entirely at £2.35 million for individuals and £2.7 million for couples. Wealth manager Quilter estimates that over 16,000 estates will surpass the £2 million mark by 2030/31, a significant increase from the 3,620 estates in 2022/23.
The Human Cost: Sean McCann from NFU Mutual illustrates the potential impact with a real-world example. A single person with a £2 million estate and a £500,000 pension currently faces a £600,000 inheritance tax bill. But from April 2027, this bill jumps to a staggering £870,000 due to the pension pot inclusion.
Professional Advice is Key: Ms. Walker emphasizes the importance of estate planning and professional financial advice. "It's crucial to understand your estate's value, including property assessments, to navigate the complexities of inheritance tax." Alex Pugh, a financial planner, agrees, stating that the new rules will "really shift the dial" and catch many people unaware, especially those who never considered themselves wealthy.
The Bottom Line: With rising asset values and outdated tax limits, the inheritance tax net is expanding. This leaves many families, especially those with frozen thresholds since 2009, vulnerable to unexpected tax bills. As the rules continue to evolve, the question remains: is this a fair system, or are families being unfairly burdened?
