It was forty years ago when Inheritance Tax (IHT) was introduced by then chancellor Nigel Lawson. It’s also often described as Britain’s “most hated” tax, despite it contributing less than 1% of the government’s revenue¹.

Understandably, death isn’t a favourite topic of conversation, especially when it comes to discussing our own mortality. But avoiding talking about IHT can have a big impact on the wealth that you pass on to your loved ones.

While IHT is often perceived as a tax for the very wealthy, that is increasingly no longer the case. IHT receipts reached a record £8.5 billion in the year to March 2026 and the average IHT bill now stands at £212,000².

The IHT tax-free threshold (or nil rate band) of £325,000 has been frozen since 2009 and will remain at that level until at least April 2031. That’s the longest period without an increase in the history of UK death taxes. If the threshold had kept pace with inflation, it would be around £525,000 today³.

This is the main reason why so many more ordinary families are being dragged into paying a tax that was originally designed for the very wealthy.

Changes to the taxation of pensions on death, announced in the 2024 Budget and set to take effect from April 2027, could significantly increase IHT bills and affect families even more.

The 67% pension tax trap

Pensions have long been regarded as a safe and tax-efficient way to pass on wealth, as unused pension pots have traditionally remained outside of the IHT net.

But after April 2027, unused pension pots for those who die over age 75 will be subject to 40% IHT and up to 45% Income Tax when beneficiaries withdraw the funds. This creates a combined effective tax rate of up to 67%.

Example:

  • Pension pot at death: £100,000
  • IHT (at 40%): £40,000
  • Remaining value: £60,000
  • Income Tax on withdrawal (up to 45%): £27,000
  • Net to beneficiaries: £33,000

Your family receives just £33,000 and £67,000 goes to HMRC.

This change could have major implications for estate planning. It’s just one more reason why it’s important to understand what impact IHT could have on your family.
