How new inheritance tax rules for unused pension pots could change your estate strategy

For many UK families, pensions have long played a double role: a source of retirement income and a useful part of estate planning. In particular, defined-contribution pension pots were often treated as assets to preserve where possible, because under the existing framework many discretionary death benefits would usually sit outside the estate for Inheritance Tax purposes. That longstanding assumption is now changing in a way that could affect how people think about spending, gifting, nominations, and passing wealth on to the next generation.

From 6 April 2027, the government says that most unused pension funds and death benefits will be brought into the value of a person’s estate for UK Inheritance Tax. In the government’s words, “This measure will bring most unused pension funds and death benefits within the value of a person’s estate for Inheritance Tax purposes from 6 April 2027.” For households with larger pension pots, rising property values, or estates already close to key thresholds, that makes this a practical planning issue now rather than something to leave until 2027.

What is changing from 6 April 2027?

The core change is straightforward in principle, even if the detail can be technical. From 6 April 2027, most unused pension funds and death benefits will be included in the deceased’s estate for Inheritance Tax purposes. This reverses an important planning advantage that often applied under current rules, where lump-sum pension death benefits did not usually fall into the estate if the scheme administrator had discretion over who received them.

The word “most” matters. The reform is not written as a blanket rule covering every pension-related payment. According to the GOV.UK policy paper, death-in-service benefits payable from a registered pension scheme and dependant’s scheme pensions from defined benefit or collective money purchase arrangements are excluded from these changes. That means some benefits will remain outside the new IHT scope, but many others will not.

The timing matters just as much as the substance. The new treatment applies to deaths on or after 6 April 2027, which creates a limited planning window. Anyone relying on a pension primarily as an estate-planning shelter may need to review that approach before the new regime begins, especially if other parts of their estate have also grown in value.

Why this could change traditional estate strategy

A common strategy under the current rules has been to spend non-pension assets first and preserve pension savings for later life or for beneficiaries. In many cases, that approach made sense because pensions could often pass on more tax-efficiently than money held in cash, investments outside wrappers, or property. Once most unused pension pots begin to count towards the estate for IHT, that sequencing may no longer be as attractive.

In practical terms, pensions may stop being the obvious “last asset to spend” for many families. A retirement plan built around preserving a large drawdown pot while using ISA savings, general investments, or other capital first could need to be reworked. The right answer will depend on the size of the estate, income needs, tax bands, and family goals, but the old rule of thumb is becoming less reliable.

This is especially relevant for defined-contribution savers. Commentary on draft legislation indicates that unspent drawdown funds and many lump-sum death benefits are central to the reform. For people who deliberately kept their drawdown pension intact as a future legacy vehicle, the planning logic may now shift towards balancing retirement income needs with estate exposure, rather than simply preserving the pension at all costs.

The growing risk of Inheritance Tax and frozen thresholds

The rule change lands at a time when Inheritance Tax thresholds remain frozen. The nil-rate band is still £325,000, and the residence nil-rate band remains £175,000. For some qualifying estates, that can mean up to £500,000 per person or as much as £1 million for some surviving spouses or civil partners when allowances are combined and transferred, but the thresholds are not rising with inflation.

The Autumn Budget 2024 measure fixed these thresholds through 5 April 2030. That matters because inflation, investment growth, and property price changes can gradually push more estates into tax even without any dramatic change in family wealth. If unused pension funds are then added into the taxable estate from April 2027, some families that previously expected to remain below the thresholds could find themselves over them.

Recent figures show why this is not a theoretical issue. HMRC’s monthly bulletin reported Inheritance Tax receipts of £7.1 billion for April 2025 to January 2026, £0.1 billion higher than the same period a year earlier. Separate reporting citing HMRC data has suggested that 4.62% of UK deaths in 2022/23 resulted in an IHT charge, with expectations that the number could rise as pensions are brought further into scope. For borderline estates, small changes in asset values now have bigger consequences.

Income Tax and IHT: the double-tax planning problem

One of the most important points for families to understand is that pension death benefits can involve both Income Tax and Inheritance Tax. Under current GOV.UK guidance, inherited pension benefits may be subject to Income Tax depending on factors such as the member’s age at death and whether benefits exceed the lump sum and death benefit allowance. From April 2027, the same pension pot may also increase the estate value for IHT.

If death occurs before age 75, some inherited lump sums can still be free of Income Tax up to the available lump sum and death benefit allowance. However, that does not prevent the new Inheritance Tax treatment from applying from 6 April 2027. In other words, a payment could still be favourable for Income Tax purposes but less favourable for IHT than families had expected.

This is why advisers increasingly need to assess tax in the round rather than looking at each rule separately. The standard lump sum and death benefit allowance remains an important technical limit, and some individuals may have protections that increase their personal allowance. But after 2027, estate planning around pensions becomes less about asking whether a benefit is taxed at all, and more about understanding which taxes may apply, when, and to whom.

Why some people are reconsidering drawdown and gifting

There is already evidence of behavioural change a of the reform. Recent reporting suggests some pensioners with larger defined-contribution pots are drawing them down faster before April 2027 in an effort to reduce future IHT exposure. That reaction is understandable, but it is not automatically the right solution for everyone.

Taking more from a pension now can create trade-offs. Withdrawals may increase current Income Tax, potentially pushing someone into a higher tax band. Money taken out also loses the tax-sheltered pension environment and may then sit in assets that are themselves taxable on death. If the withdrawn funds are gifted away, the seven-year rule for potentially exempt transfers becomes relevant, so a donor who dies within that period may still leave a tax problem behind.

That said, the reform does make lifetime gifting more relevant for some households. If pensions lose part of their special shelter status for IHT, families may be more willing to use surplus wealth during life rather than preserving large pots for inheritance. The key is not to rush into action, but to compare options carefully through updated cashflow planning, gifting analysis, and retirement-income modelling.

Defined benefit, defined contribution, and nomination forms

Not every pension arrangement is affected in the same way. For defined-benefit members, the detail matters. Certain lump-sum death benefits may be caught, while dependant pensions remain outside scope. That means DB members and trustees may need product-by-product analysis rather than assuming a final salary or career average scheme is untouched by the changes.

For defined-contribution members, the impact is often more direct. Unspent drawdown funds are at the heart of the reform, which undermines the old idea that a DC pension could reliably act as an Inheritance Tax shelter for the next generation. People with substantial personal pensions, SIPPs, or other DC arrangements may therefore have the most urgent need to review beneficiary plans and wider estate strategy.

It is also sensible to revisit nomination forms now. Nominations will still matter because they help indicate who should receive the benefits, and providers often rely on them when exercising discretion. However, the reform means nomination no longer reliably determines whether those funds sit outside IHT. In short, nominations remain important for distribution, but less powerful as a tax shield than many people assumed.

Administration, delays, and what families should expect

The administrative side of the reform is easy to overlook, but it could have a real impact on bereaved families and executors. From 6 April 2027, pension scheme administrators will need to report details of relevant unused pension funds and death benefits to HMRC and pay any Inheritance Tax attributable to those benefits. As the government put it, “PSAs … will be required to report details of unused pension funds and death benefits payable in respect of a deceased member to HMRC … and pay any Inheritance Tax attributable to those benefits.”

The government’s formal response published on 21 July 2025 confirmed that the reporting-and-payment framework would proceed, with updated legislation allowing pension scheme administrators and personal representatives to exchange information for both IHT and any Income Tax due. That is a strong signal that the reform moved well beyond an early announcement and into implementation detail.

For families, this may mean slower and more document-heavy estate administration where pensions are involved. A practical risk is delay in paying death benefits while values are confirmed and liabilities are calculated. Executors, beneficiaries, and advisers may need to coordinate earlier than before, particularly where the pension forms a large part of the overall wealth picture or where the estate is close to the tax thresholds.

Practical steps to review before 2027

For many households, the right next step is not a dramatic overhaul but a careful review. People with large defined-contribution pensions, valuable property, or estates close to the £325,000, £500,000, or £1 million family thresholds are obvious candidates for an urgent estate-plan check. Even where no immediate action is taken, it is sensible to update cashflow planning and understand how the 2027 rules could affect the family balance sheet.

A review may include looking again at withdrawal strategy, beneficiary nominations, expected retirement spending, gifting plans, protection needs, and how assets are split between spouses or civil partners. It may also involve reassessing whether “spend taxable assets first, preserve the pension for heirs” still makes sense. For some families the answer may still be yes, but for many others it may now be only part of the picture rather than the default rule.

Most importantly, any changes should be made in context. Reducing IHT is only one objective. A good estate strategy should also preserve financial security in retirement, avoid unnecessary Income Tax, reflect family wishes, and keep administration manageable for loved ones. Clear, regulated advice can be especially valuable where several tax rules overlap or where more than one pension scheme is involved.

The new inheritance tax rules for unused pension pots are significant because they change not just a technical tax treatment, but the planning logic many families have followed for years. From 6 April 2027, pensions may no longer sit apart from the rest of the estate in the way people expected, and that means retirement-income planning and estate planning need to be looked at together.

For UK residents, the reassuring message is that there is still time to review the position before the rules take effect. A calm, informed review of pensions, property, gifts, nominations, and likely estate values can help households make practical decisions without pressure. The aim is not simply to react to a tax change, but to build an estate strategy that remains sensible, tax-aware, and aligned with family goals under the new rules.
