Direct answer: From 6 April 2027, most unused defined contribution pension funds and pension death benefits will be included in the inheritance tax calculation. This ends the long-standing position where pensions typically sat outside the estate for IHT purposes.

Although income tax rules on pension death benefits remain unchanged, the inclusion of pensions in the estate means families may now face inheritance tax and income tax applying to the same pension fund, particularly where death occurs after age 75.

The Position Before April 2027

Under current rules, most defined contribution pension arrangements do not form part of the deceased's estate for inheritance tax purposes.

In broad terms:

This treatment has led many families to preserve pensions while spending other assets first.

What Changes from 6 April 2027

From 6 April 2027:

This represents a structural change in how pensions are treated on death.

The Double Tax Risk Explained

The most significant consequence of the April 2027 change is the potential for double taxation.

First, inheritance tax:

Second, income tax:

This risk is greatest where death occurs at age 75 or over.

Worked Example: The 64% Outcome

An individual dies after age 75 on or after 6 April 2027 with a £100,000 pension fund. The estate already exceeds the inheritance tax thresholds. The beneficiary is a higher rate taxpayer.

  • Pension added to estate: £100,000
  • Inheritance tax at 40%: £40,000
  • Pension remaining: £60,000
  • Income tax at 40% on withdrawal: £24,000
  • Net amount received: £36,000
Total tax paid: £64,000 | Effective tax rate: 64%
For additional rate taxpayers, the effective rate can exceed 87%.

The Spousal Exemption and Why It Can Mislead

Pensions left to a surviving spouse or civil partner remain exempt from inheritance tax on the first death.

However:

For estates already above inheritance tax thresholds, this can result in a substantial tax bill later, often without further planning having taken place.

The "Tax Free" Pension Inheritance That Isn't

Many families assume leaving a pension to a spouse is "tax free". While it avoids IHT on the first death, the combined estate on the second death may face significant IHT exposure on the pension value — at a time when the surviving spouse has less opportunity or inclination to plan.

Nomination Strategy Becomes Critical

After April 2027, pension nomination decisions carry much greater weight.

Key considerations include:

There is no universal answer. The correct approach depends on the wider estate structure.

Executor and Administration Risk

Including pensions in the inheritance tax calculation increases the burden on personal representatives.

Executors may need to:
