UK Pensions Face 40% Inheritance Tax in 2027 – What Expats Should Do Now

The Context and Scope of the April 2027 Changes

From 6 April 2027, a seismic shift in British tax law will fundamentally alter how pensions are treated within inheritance tax planning. For decades, pensions have occupied a privileged position in the UK tax system - largely exempt from inheritance tax upon death. This exemption has made pensions an increasingly attractive vehicle for wealth preservation and intergenerational transfer. However, the government's Autumn Budget 2024 announcement has brought this era to an abrupt end. The change represents one of the most consequential pension tax reforms since the introduction of pension flexibility in 2015, and for British expats, the implications are particularly acute.

The decision to bring unused pension funds and death benefits into the scope of inheritance tax reflects a broader government objective: closing what ministers perceive as a tax avoidance loophole. With an estimated £1.46 billion expected to be raised by 2029/30 through this change alone, the Treasury has signalled that pension wealth will no longer be treated as a privileged asset class. For expats managing complex cross-border estates, this reform demands immediate attention and strategic recalibration of existing wealth transfer plans.

What makes this reform particularly significant for British expats is the interaction between domicile rules, pension valuation, and the nil-rate band. Expats with split assets across multiple jurisdictions must now factor pensions into their UK inheritance tax liability in entirely new ways. Those who have been relying on pensions as a tax-efficient vehicle for leaving assets to beneficiaries must fundamentally reconsider their approach.

The Scope of the April 2027 Changes

From 6 April 2027, most unused pension funds will be brought into the valuation of the deceased's estate for inheritance tax purposes. This change applies to both defined contribution and defined benefit pension schemes, though the practical application differs somewhat between the two. The government's consultation process, which concluded in 2024, narrowed the scope to exclude certain death benefits whilst maintaining exemptions for spousal transfers and charitable donations. However, the breadth of the change remains substantial.

The key elements of the reform include:

• Uncrystallised funds - pension pots that have not yet been drawn down will count towards the estate
• Residual pension funds - amounts remaining after partial withdrawals or annuitisation will be captured
• Pension death benefits - lump sum payments that would be paid to beneficiaries will now be assessed against the nil-rate band
• Defined benefit pension schemes - certain DB death benefits, including lump sum payments and pension protection schemes, will fall within the new rules
• Defined contribution schemes - DC pots will be valued at the date of death for IHT purposes
• Pension Commencement Lump Sum amounts - any PCLS not yet claimed will form part of the estate
• Income drawdown arrangements - funds held within drawdown will be included in the valuation

It is important to note that death-in-service benefits paid directly from a registered pension scheme will remain outside the scope of inheritance tax. Equally, transfers to surviving spouses or civil partners will continue to benefit from the spouse exemption, provided domicile requirements are satisfied. Transfers to registered charities will also remain exempt, offering a limited planning opportunity for those with philanthropic objectives.

The Treatment of Defined Contribution Pensions

Defined contribution schemes present a particularly complex landscape for the 2027 changes. Under the new rules, the value of a DC pot at the date of death becomes the amount included in the estate for inheritance tax purposes. This creates an immediate administrative challenge: the actual value passed to beneficiaries may differ materially from the value at death, depending on market movement and the timing of distribution.

For expats with DC pensions held in the UK and beneficiaries resident in multiple countries, this divergence between valuation date and actual distribution creates planning complications. If a pension pot worth £500,000 at death is worth £520,000 by the time it is distributed to beneficiaries, the estate has paid inheritance tax based on a lower figure. Conversely, if markets have fallen, personal representatives may face demands for inheritance tax on assets that no longer exist in their stated value.

The approach taken by the government is to value pensions at the date of death, not the date of actual distribution. This reflects the general principle of estate valuation under UK inheritance tax law, but it introduces timing risk for expat beneficiaries, particularly those in jurisdictions where exchange rate fluctuations are significant or where distribution timescales are prolonged.

Defined contribution schemes also introduce questions about partial crystallisation. If an individual has drawn down £200,000 from a £1 million DC pot and left £800,000 uncrystallised at death, the entire £800,000 will be subject to inheritance tax. This differs from the position under previous planning, where the ability to pass down uncrystallised funds with no inheritance tax liability made DC pensions exceptionally tax-efficient from an intergenerational wealth transfer perspective.

The Treatment of Defined Benefit Pensions

Defined benefit schemes present a different set of considerations. Many DB schemes provide a death benefit in the form of a lump sum, calculated according to scheme rules - typically five times salary or a multiple of the member's pension, depending on the scheme documentation. From April 2027, these lump sums will fall within the scope of inheritance tax.

For expats who are members of DB schemes operated by previous UK employers - either through ongoing employment or deferred benefits - this change is material. A DB member with a pension of £50,000 per annum and a scheme that provides five times salary as a death benefit lump sum faces a potential inheritance tax charge of up to £100,000 on that death benefit alone (at 40% IHT on the amount exceeding the nil-rate band, assuming the nil-rate band has been fully utilised).

DB schemes also offer other death benefits that will now be caught: lump sum death benefits payable under scheme rules, pension protection lump sums, death in service benefits for former employees, dependant's pensions enhanced or commuted to lump sums, and scheme-specific benefits such as widow's or widower's pensions taken as lump sums

Some DB schemes provide for automatic increases in death benefits. Expats should review scheme documentation to understand precisely what death benefits are available and what the valuation methodology will be for inheritance tax purposes. The personal representatives of the deceased will be responsible for providing the pension scheme trustees with details of the estate's inheritance tax position and arranging payment of any tax due.

The Nil-Rate Band and Expat Domicile Complications

For British expats, the interaction between the new pension IHT rules and domicile status is critical. The nil-rate band - currently £325,000 - is applied first against the estate before the 40% inheritance tax rate applies. For a UK-domiciled individual dying on or after 6 April 2027 with a £1 million uncrystallised pension pot and £500,000 in other assets, the pension and assets combined are £1.5 million. Against a nil-rate band of £325,000, inheritance tax becomes due on £1.175 million at 40%, yielding a tax bill of £470,000.

This calculation becomes significantly more complex for expats with deemed domicile status or those who have acquired non-UK domicile. An individual who is deemed UK domiciled - including any individual who was UK domiciled in the previous three years - will be assessed to inheritance tax on their worldwide assets, including UK and overseas pensions. Expats who have acquired non-UK domicile status may benefit from the remittance basis in relation to non-UK assets, but UK pensions will always be treated as UK assets and subject to inheritance tax.

Thus UK IHT After the 2025 Domicile Reform: Complete Expat Guide becomes essential reading for anyone seeking to understand how recent domicile law changes interact with the new pension rules. The cumulative effect of pension inclusion and domicile reform creates a materially different inheritance tax landscape.

For expats with a non-UK domicile acquired prior to 6 April 2017, the remittance basis applies to non-UK assets but not UK assets. However, most pension wealth is held in UK-registered schemes, meaning even non-domiciled expats cannot escape the new charge. The timing of domicile acquisition or loss becomes increasingly important in pension planning.

Nil-Rate Band Cumulation and Family Planning

Under the current rules, each individual has their own nil-rate band of £325,000. If one spouse dies and leaves assets to the surviving spouse - which benefits from the spouse exemption - the unused portion of the deceased spouse's nil-rate band can be transferred to the survivor. This is known as nil-rate band transfer.

With pensions now being included in estate valuations, the scope for nil-rate band transfer planning becomes more constrained. A couple where one partner has a £600,000 DC pension will immediately consume a substantial portion of the available nil-rate band. If the deceased leaves their pension to their spouse, no inheritance tax is due (assuming the spouse exemption applies), but the nil-rate band remains unused and available for transfer. If, however, the deceased leaves their pension to adult children, inheritance tax becomes due immediately.

For expat couples with combined pension wealth exceeding £650,000, the mathematics become punitive. Planning to ensure optimal use of both nil-rate bands - whether through lifetime planning, trust structures, or careful consideration of death benefit nomination forms - becomes essential.

The distinction between spousal exemption and the nil-rate band is critical. Transferring pension death benefits to a spouse is exempt from inheritance tax regardless of amount, provided the spouse is deemed domiciled in the UK or the deceased was not domiciled in the UK (in which case the exemption is capped at £325,000). This exemption remains unaffected by the April 2027 changes.

Pensioners and Pension Commencement Lump Sums

One of the lesser-discussed aspects of the 2027 changes concerns individuals who have already crystallised their pensions but have not claimed their full Pension Commencement Lump Sum. Under current rules, individuals can take up to 25% of their pension pot as a tax-free lump sum when they first access their pension. Some individuals have elected not to take their full PCLS, preferring instead to retain the flexibility to claim it at a later date.

From 6 April 2027, any unclaimed PCLS will form part of the estate for inheritance tax purposes. For an individual with a £400,000 pension pot who has taken income drawdown but not claimed their full £100,000 PCLS, that £100,000 (the unclaimed element) will be subject to inheritance tax when the individual dies.

This creates an interesting planning opportunity in the window between now and 6 April 2027. Any individual over the age of 55 who has not yet claimed their full PCLS may wish to consider doing so before the April 2027 deadline. Claiming the PCLS in advance of the new inheritance tax rules removes that element from the estate entirely, as the PCLS is a lifetime benefit, not a death benefit.

For expats, this planning point is particularly valuable. An expat aged 60 with an unclaimed PCLS of £75,000 could withdraw this tax-free before April 2027, invest it, and remove this amount from future inheritance tax exposure. The complexity lies in understanding scheme rules - not all schemes permit retrospective PCLS claims, and some impose conditions or time limits.

Business Property Relief and Pension Interaction

Another planning layer concerns the potential interaction between Business Property Relief (BPR) and pension funds. Business Property Relief provides relief from inheritance tax for certain business assets, including unquoted shares in trading companies. Relief is available at 100% for operational holdings and 50% for investment holdings.

For expats who are company directors or business owners, the interaction between pension wealth held in pension schemes and BPR-eligible business assets becomes important. If an individual has a £2 million trading company (eligible for 100% BPR) and a £600,000 pension pot, the pension remains fully subject to inheritance tax whilst the company benefits from full relief. The combination of these two assets creates distinct inheritance tax planning opportunities.

In some cases, expats have funded pension schemes through business vehicles or have accumulated significant pension wealth alongside business ownership. The 2027 changes effectively differentiate between business and pension wealth, potentially making business succession planning more attractive than pension-based wealth accumulation from an inheritance tax perspective.

Personal Representatives and Administrative Burden

From 6 April 2027, personal representatives of the deceased will be responsible for reporting and paying any inheritance tax due on unused pension funds and death benefits. This represents a material shift from the current position, where pension death benefits flow outside the estate and do not generate an inheritance tax liability for the PR.

Under the new rules, personal representatives must obtain valuations of all pension assets as at the date of death, report the pension value to HMRC as part of the inheritance tax account, calculate inheritance tax due on pension death benefits, instruct the pension scheme to withhold 50% of taxable benefits for up to 15 months after death, provide beneficiaries with accurate tax statements, and maintain records and correspondence with pension trustees

For expats with pension schemes held in multiple jurisdictions - both UK and overseas - this creates an administrative challenge. Each scheme must provide death benefit valuations, and each must coordinate the timing of distributions with the overall inheritance tax settlement. Some overseas schemes may not be structured in a manner that facilitates coordination with UK inheritance tax rules, creating practical difficulties.

The 15-month withholding period is designed to provide executors with time to settle inheritance tax liabilities. However, for beneficiaries relying on death benefits for income or capital, the delay in receiving their full benefit can be material. Expat beneficiaries particularly may face cash flow challenges if they are relying on pension death benefits to finance relocation, settlement in a new jurisdiction, or other material expenses.

Expat-Specific Planning Considerations

For British expats, the 2027 pension IHT changes create several specific planning challenges that differ from those facing UK-resident individuals. These include cross-border complexity, currency risk, domicile timing, and overseas tax regime interaction.

Expats in tax treaty jurisdictions including the UAE, Singapore, and Hong Kong must consider whether their host jurisdiction recognises UK inheritance tax. Some jurisdictions impose no inheritance tax, creating asymmetry where UK IHT applies without offset from the residence jurisdiction.

Those who have recently acquired non-UK domicile should review their pension arrangements. An individual acquiring non-UK domicile six months ago protects overseas assets, but UK pensions remain subject to full UK IHT scope. For expats planning UK return, deemed domicile applies even without permanent residence, triggering inheritance tax on overseas pensions as well.

Expats should consider currency dimension risk. A pension valued at £500,000 sterling but inherited by US-based beneficiaries faces currency fluctuation. Inheritance tax is calculated on sterling values, but beneficiaries in other currencies face conversion complexity and potential losses.

Whilst the state pension itself does not form part of the inheritance tax estate, access depends on complex contribution rules. How to Protect Your UK State Pension While Living Abroad provides essential context on protecting state pension rights through voluntary contributions.

UAE and Middle East Expat Considerations

For expats based in the UAE and other Gulf states, the 2027 pension IHT changes create a particularly acute planning issue. The UAE has no inheritance tax or succession duties, meaning that wealth accumulated there is not subject to any direct succession tax. However, if an expat holds UK pensions whilst residing in the UAE, those pensions become subject to UK inheritance tax upon death, even though the UAE itself imposes no tax on succession.

This asymmetry means that expats in the UAE with substantial UK pension wealth face an unexpected tax charge. A UAE-based expat with £1 million in UK pension wealth and £500,000 in UAE assets faces inheritance tax on the full pension if they are deemed UK domiciled or if they have not satisfied the statutory tests for non-UK domicile.

Articles such as UK IHT for Long-Term Expats in the UAE: Post-Reform Planning address the specific planning strategies available to UAE-based expats, and these become even more critical in light of the 2027 changes. Planning around domicile acquisition, pension structuring, and cross-border arrangements is essential for this cohort.

Implementing Changes Before April 2027

Expats have until 6 April 2027 to implement changes that may mitigate the impact. Key planning opportunities include:

• Claim unclaimed Pension Commencement Lump Sums before April 2027 to remove that amount from the estate entirely
• Crystallise pension funds into income drawdown arrangements to minimise remaining estate value subject to inheritance tax
• Make lifetime gifts of non-pension assets to reduce overall estate and provide additional nil-rate band capacity
• Review death benefit nominations on pension schemes to optimise spousal exemptions or trust structures for minors

Expats should also assess their domicile position. The 2027 changes make acquiring non-UK domicile more valuable, as it protects overseas assets. However, domicile planning requires proper legal and tax advice, as the tests for non-UK domicile are stringent and require genuine intention and conduct. Finally, expats should review their overall estate plan, including wills, powers of attorney, and trust documents, to reflect the changed inheritance tax landscape.

Professional Planning Fit

The 2027 pension IHT changes represent a fundamental shift in inheritance tax planning for British expats. The complexity arises from the interaction between pension valuation, domicile rules, nil-rate band calculations, and the administrative burden placed on personal representatives. No single planning strategy will suit all expats - each individual's circumstances, including domicile status, pension wealth, family structure, and jurisdiction of residence, will dictate the optimal approach.

Expats with pension wealth exceeding £325,000 should treat the 2027 changes as a material planning prompt. The calculations required to understand the inheritance tax position and to identify available mitigation strategies require specialist knowledge of both UK inheritance tax law and the specific expat circumstances. Personal circumstances such as domicile status, the existence of a surviving spouse, and the structure of other assets will all influence the planning approach. Getting this right requires comprehensive advice from tax professionals with genuine expertise in cross-border wealth planning.

Soft Next Step

If you have pension wealth held in the UK whilst working or retired abroad, or if you are anticipating inheriting a UK pension, now is the time to review your position. The window for some planning steps - such as claiming unclaimed Pension Commencement Lump Sums - closes on 6 April 2027. For others, such as domicile planning or reorganisation of death benefit nominations, there is more flexibility, but early implementation allows proper implementation and verification.

The questions you should be asking your adviser are straightforward: How much of my estate is comprised of pension wealth? What is my domicile status, and how will it be assessed on death? Are there any unclaimed benefits within my pension arrangements? What are my death benefit nominations, and are they aligned with my overall estate plan? What is my inheritance tax position under the new rules, and what mitigation steps are available? These questions require considered answers from professionals who understand both pensions and cross-border tax planning.

Final Takeaway

Pension inheritance tax reform, effective from 6 April 2027, fundamentally reshapes the landscape for British expat wealth planning. Pensions, long treated as a privileged asset class from an inheritance tax perspective, will now be brought fully within the scope of inheritance tax on death. For expats with significant pension wealth held in UK schemes, this change is material and demands action. The interaction between domicile status, nil-rate band calculations, and the valuation of pension death benefits creates a complex planning landscape in which individual circumstances matter greatly. The window for implementing changes remains open but is narrowing. Professional advice, tailored to individual circumstances and grounded in genuine expertise in cross-border pensions and inheritance tax, is not merely advisable but essential.
