UK Inheritance Tax for Expats: What Changes in April 2027

From April 2027, the UK government will bring unused pension assets into the scope of inheritance tax for the first time. For UK nationals living abroad with existing pension funds, this is one of the most consequential changes to UK estate planning in decades.

If you hold a UK pension and live outside the United Kingdom, the April 2027 deadline is worth understanding well in advance. Decisions about pension structure, gifts, and estate planning often take years to work through properly, and some of the most effective strategies require time that is now measurably finite. With just over eleven months remaining before the rules change, the planning window is narrowing.

This guide explains what changes, why it matters specifically for expats, and the kinds of questions worth raising with a regulated specialist now.

UK Inheritance Tax: The Current Position

Inheritance tax applies in the United Kingdom at 40% on the value of an estate above the nil-rate band. The standard nil-rate band is £325,000. Married couples and civil partners can combine allowances, and the residence nil-rate band (up to £175,000 per person, subject to conditions) may apply when a qualifying family home passes to direct descendants.

For UK nationals living overseas, domicile is the concept that determines the scope of IHT exposure. Individuals who are UK-domiciled, or deemed UK-domiciled under the 15-out-of-20-years residence rule, are subject to UK IHT on their worldwide assets. Non-UK-domiciled individuals are generally subject to UK IHT only on UK-situated assets.

Until April 2027, pension funds have represented one of the most significant IHT reliefs available to UK nationals. Defined contribution pension schemes, SIPPs, and most occupational defined contribution arrangements have typically fallen outside the deceased's estate entirely. Nominated beneficiaries can currently receive unspent pension assets without IHT applying, regardless of the fund value. For many expats with substantial UK pension pots, this has been a cornerstone of their broader estate planning.

What Changes in April 2027

From April 2027, unspent pension funds and most lump-sum death benefits will be brought within the scope of UK inheritance tax.

In practice, the value of unused pension assets at the point of death will be added to the total estate valuation. Where the combined estate, now including pension funds, exceeds the available nil-rate band, the excess will be subject to the standard 40% IHT charge.

For individuals whose estate planning has been structured around pension assets sitting outside the IHT calculation, this change fundamentally alters the position. A SIPP or defined contribution scheme that was previously IHT-neutral may become the largest single source of IHT liability in the estate.

The change also introduces new responsibilities for pension scheme administrators. Trustees will be required to calculate and pay any IHT due on pension death benefits before releasing funds to beneficiaries, adding a layer of complexity to what is already a technically intricate process. HMRC is still working through some implementation details, which is one reason why specialist oversight from an adviser who follows these developments closely is particularly valuable at this stage.

Why Expats Are Disproportionately Affected

The April 2027 change has particular resonance for UK nationals living abroad. Several factors combine to create elevated exposure.

Accumulated, untouched pension pots. Many expats spent years building UK pension assets during their UK working years before relocating. Once abroad, ongoing pension contributions often cease, but the existing pot continues to compound. Pension funds that have grown over one or two decades, without drawdown, can represent substantial sums that will now fall squarely within the IHT calculation.

Domicile uncertainty. Expats who believe they have established non-UK domicile should be aware that domicile is assessed by HMRC against a strict legal test, not simply by length of time abroad or the acquisition of a new passport. Individuals who remain UK-domiciled, or are deemed UK-domiciled, face IHT on worldwide assets including UK pension funds. This is a technical determination that requires specialist advice tailored to individual circumstances.

No active UK adviser relationship. Many expats do not have a UK-based financial adviser monitoring their position. Changes to UK tax law, including the April 2027 reforms, can pass without a prompt to review. The result is that the planning window narrows without the individual being aware of it.

Cross-border estate complexity. Estates spanning multiple jurisdictions, which is common among long-term expats, require coordination across different legal systems and tax regimes. Adding a material UK IHT liability from what was previously a tax-efficient pension asset introduces a layer of complexity that requires careful planning, often across more than one specialist discipline.

The 7-Year Rule and Why Timing Matters Now

One of the most commonly used IHT planning tools is the gifts exemption. Gifts made to individuals more than seven years before death are generally exempt from UK IHT. Gifts made within seven years may be subject to taper relief, reducing the effective charge, but only partially exempt depending on how close to death the gift was made.

For expats thinking about estate planning in the context of April 2027, the 7-year clock has a straightforward implication: a gift made today begins a seven-year period that completes in May 2033. A gift made after April 2027 will not be fully outside the estate until 2034 or later. Where gifting forms part of an estate planning strategy in response to the pension change, earlier action extends the benefit of the clock.

This is not a reason to act without proper analysis. Gifts carry their own tax consequences in some jurisdictions, and in some countries a gift may trigger local tax obligations regardless of the UK position. The decision to make gifts, establish trusts, or restructure an estate is one that requires full specialist advice tailored to individual circumstances. What the 7-year rule illustrates, however, is why advisers consistently emphasise that IHT planning requires a long time horizon. The April 2027 deadline is not the starting point for planning; it is a point by which certain decisions need to have been made.

Questions Worth Raising With a Specialist

The April 2027 changes create a clear set of questions that a specialist in cross-border IHT and estate planning can help to assess. The answers will depend entirely on individual circumstances.

What is the current value of UK pension assets, and what is the projected IHT liability under the new rules? What is the domicile position, and has it been formally reviewed by a specialist recently? Are there legitimate gifting, trust, or drawdown strategies that could reduce the overall IHT exposure, and are any of those time-sensitive given the April 2027 deadline? How do existing wills, beneficiary nominations, and current estate planning documents interact with the new pension IHT rules?

These are questions for an expat financial adviser with specific experience in UK IHT and cross-border planning. They require individual analysis, not a general guide. A specialist can model the projected liability under the new rules and help identify what options are available.

Frequently Asked Questions

Do the April 2027 IHT changes apply to expats who no longer live in the UK?

The April 2027 changes apply to UK-registered pension schemes. Whether IHT applies in your case depends primarily on your domicile status. UK-domiciled and deemed UK-domiciled individuals are subject to IHT on worldwide assets, including UK pension funds. Non-UK-domiciled individuals are generally subject to IHT only on UK-situated assets. Domicile and pension siting questions are technical and should be reviewed by a regulated specialist.

I have a SIPP I have not touched since leaving the UK. Does this change affect me?

If you have an undrawn SIPP and you are UK-domiciled or deemed UK-domiciled, the value of that SIPP will likely be included in your estate for IHT purposes from April 2027. The extent of the exposure depends on the size of the fund, the value of your other assets, and the nil-rate band allowances available to your estate. A specialist can help you assess the projected liability and what options may be available.

Does the April 2027 change affect defined benefit (final salary) pensions?

The position for defined benefit pensions differs from defined contribution schemes. DB pensions typically pay an income to the member during retirement, and after death may continue as a spouse's or dependant's pension. These are generally not held as a lump-sum fund in the same way as a SIPP or defined contribution scheme, and the April 2027 changes are primarily directed at defined contribution arrangements and lump-sum death benefits. That said, the detail varies by scheme, and if you have a DB pension with a significant death benefit component, a specialist can review whether there is any exposure.

Can I reduce the IHT exposure on my pension before April 2027?

There are strategies that a specialist may be able to help you consider, including the structure of beneficiary nominations, the sequencing of retirement drawdown, gifting arrangements, and trust structures. The appropriateness of any strategy depends entirely on individual circumstances, including domicile status, residency plans, the value of the pension, and the overall estate position. This is an area where regulated specialist advice is required rather than general guidance.

How does UK IHT interact with inheritance or estate taxes in my country of residence?

Some countries have their own inheritance, estate, or gift taxes. A small number have double tax treaties with the United Kingdom that affect how UK IHT interacts with local charges. The interaction varies significantly by jurisdiction. If you live in a country with its own succession or estate tax system, the combined effect of both regimes is something a specialist should model as part of any estate planning review, to avoid paying tax in two jurisdictions on the same assets.
