Pension Fund Inheritance Tax Changes 2027: UK Rules Explained

If you’ve spent decades building a pension pot with the idea of passing it on tax-efficiently, the rules are about to change in ways that could catch even careful planners off guard. From 6 April 2027, unused pension funds will typically count toward your estate for Inheritance Tax purposes — a shift that reverses a long-standing advantage. The good news: for most people, the change will matter less than headlines suggest. Around 213,000 estates contain pension wealth each year, but government estimates suggest only about 10,500 will face newly triggered IHT charges once the rules take effect.

Change effective date: 6 April 2027 ·
Estates affected estimate: 213,000 annually ·
Most estates liability: None expected ·
Key inclusion: Unused pension funds ·
Applies to deaths: On or after 6 April 2027

The table below summarises the key figures that define who faces the new IHT charge and who does not.

What pension changes are coming in 2027?

From 6 April 2027, unused pension funds and death benefits will be included in the estate for Inheritance Tax purposes — a fundamental shift in how the UK’s pension system treats wealth passed on after death. HM Revenue & Customs announced the change at the Autumn Budget 2024, with detailed technical guidance published on 26 November 2025.

Current rules on unused pensions

Under the existing framework, pensions sit outside the estate for IHT purposes, meaning they can pass to beneficiaries tax-free in terms of Inheritance Tax. This advantage stems partly from the pension freedoms introduced in 2015, which gave people more control over how they accessed their retirement savings and made it viable to use pensions as a vehicle for intergenerational wealth transfer. The abolition of the lifetime allowance in March 2023 further reinforced this trend.

Post-2027 inclusion in estates

From 2027, defined contribution pensions will generally be subject to the standard 40% IHT rate once estate value exceeds the nil-rate band of £325,000 and the residence nil-rate band of £175,000. The policy aims to prevent pension schemes from functioning primarily as estate-planning vehicles rather than retirement funding mechanisms.

What the 2027 rule changes mean for your pension and estate

Government estimates suggest that around 213,000 estates containing pension wealth are processed each year. Of these, approximately 10,500 are expected to face new Inheritance Tax charges in 2027-28 — roughly 5% of the total. Put another way, about 95% of estates with pension wealth will see no additional tax liability under the new rules.

Impact on estate value

The inclusion of pension funds adds a new category of asset to estate calculations. For estates already near or above the combined nil-rate band thresholds, pension wealth could push the total liability higher. However, the standard exemptions and reliefs that apply to other estate assets — such as business property relief or agricultural relief — do not extend to pension funds under the new rules.

Families potentially facing new liabilities

Families most likely to face new charges are those where the deceased had substantial defined contribution pension pots but relatively modest other assets. A retired individual with a £500,000 SIPP but a modest family home, for example, could find that the pension funds push the estate above the nil-rate threshold for the first time.

How to avoid inheritance tax on pensions

For those with large pension pots who want to minimise the IHT exposure of their estate, several planning options exist — though all require action before April 2027.

Drawdown before death

One straightforward strategy involves crystallising pension funds before death through flexi-access drawdown. Once funds are drawn as income or transferred to a different vehicle, they leave the pension environment and enter the wider estate. However, this approach trades the IHT exemption for income tax liability during the pension holder’s lifetime, and reduces the capital available for retirement income.

Spouse nominations

Naming a spouse or civil partner as the primary beneficiary remains an effective way to defer IHT on pension funds. Transfers between spouses are exempt from Inheritance Tax, and the surviving spouse can continue to benefit from the pension tax wrapper. The exemption means spouses can receive pension funds without triggering an IHT charge at the time of transfer.

Gifting strategies

Using annual gifting allowances or making larger gifts from other assets can reduce the non-pension estate value, leaving more headroom within the nil-rate band for any pension funds that do fall into the estate. The nil-rate band of £325,000 is not reduced by the pension inclusion alone — it applies to the estate as a whole, so reducing other assets can help preserve the threshold.

Do pensions form part of an estate in the UK?

Before 6 April 2027, the answer for most pension types is no — pensions exist in a distinct legal space from the estate proper. This separation has been one of the primary advantages of funding a pension: accumulations within the pension wrapper escape IHT regardless of how large they grow.

Pre-2027 rules

Under pre-2027 rules, personal representatives do not include pension assets in the IHT return. Scheme administrators pay death benefits directly to nominated beneficiaries without reference to the estate’s IHT position. This applies whether the pension is a defined contribution arrangement like a SIPP or a trust-based occupational scheme.

2027 changes overview

From 6 April 2027, this changes fundamentally. Personal representatives become responsible for declaring pension assets in the IHT return and accounting for any tax due. Scheme administrators can be directed to withhold 50% of taxable benefits for up to 15 months to allow time for IHT payment. The policy guidance published by HMRC on 26 November 2025 confirms that personal representatives bear this liability, not the scheme administrators as originally proposed.

What are the pension inheritance tax changes for spouses?

Spouses and civil partners retain their exemption from Inheritance Tax on pension transfers — a key protection that means most married couples or civil partners will not face an immediate IHT charge on pension inheritance.

Spouse exemptions

Transfers of pension funds to a surviving spouse or civil partner remain exempt from Inheritance Tax regardless of the new rules. This exemption applies across all registered pension schemes and means that pension funds can continue to pass between partners without triggering an IHT liability at the point of transfer.

Post-2027 nuances

However, the spousal exemption is not unconditional. The exemption applies to the initial transfer, but subsequent draws from the pension by the surviving spouse could have different tax consequences depending on their age and the structure of the inherited arrangement. Beneficiaries who receive pension funds as drawdown after the deceased was 75 face income tax at their marginal rate.

The practical effect is narrower than the headline change suggests: for the vast majority of estates containing pension wealth, no additional Inheritance Tax liability will arise. However, the 10,500 estates estimated to face new charges represent real families who may have planned their retirement around the tax advantages of pension accumulation. For those individuals, the window for strategic action closes on 5 April 2027.
