UK Inheritance Tax Changed in April 2025. If You're a UK Expat in Malaysia, Here's What It Means for Your Estate
The rules governing UK Inheritance Tax changed fundamentally on 6 April 2025. If you are a British expat living in Malaysia, your worldwide estate may now be inside the UK IHT net regardless of how long you have been away. The old domicile test has been replaced. The new “long-term UK resident” test catches more people, triggers earlier than expected, and lifts more slowly than most assume. This post explains exactly what changed, who it affects, and what you can do about it.
What Changed on 6 April 2025
Until April 2025, UK Inheritance Tax exposure for non-residents was determined by domicile. A complex, often contested concept involving intention and strong ties to the UK. From 6 April 2025, HMRC replaced it with an objective, residence-based test.
The Long-Term UK Resident Test
Under the new rules, you become a “long-term UK resident” for IHT purposes if you have been resident in the UK for at least 10 of the last 20 tax years. Once that threshold is crossed, your worldwide estate falls within the scope of UK Inheritance Tax, not just your UK-sited assets.
The threshold works on a rolling 20-year window. Your years in Malaysia count toward reducing that exposure over time. But years spent in the UK before relocating count against you, and for most senior professionals who built their careers there, the arithmetic is likely unfavourable.
For a senior oil and gas executive who spent 12 years working in Aberdeen or London before moving to Kuala Lumpur, the calculation is straightforward and the result is uncomfortable. You have crossed the 10-year threshold. Your global estate, including investments held in Irish UCITS funds on an offshore platform, is in scope for UK IHT at 40% above the nil-rate band. Today. Not in some theoretical future.

The Tail Provision: Your Liability Does Not End When You Leave
This is the element that catches most people off guard. Once you cross the 10-year threshold, your worldwide IHT exposure does not switch off the moment you land at KLIA. There is a tail period during which your global estate remains within UK IHT scope even after you have stopped being UK resident.
The tail depends on how many qualifying years you accumulated:
10 to 13 years of UK residence: estate remains in scope for 3 full UK tax years after leaving
14 to 16 years: 4 tax years after leaving
17 to 19 years: 5 tax years after leaving
20 years: 6 tax years after leaving
If you moved to Malaysia in 2023 after 12 years of UK residence, your worldwide estate is still inside the UK IHT net until at least 5 April 2027. The tail clock starts from the end of the UK tax year in which you ceased UK residency, not from the date you departed.
The practical consequence: relocation does not solve the problem. It starts a timer. Your estate plan must reflect this exposure accurately for the years immediately following departure.
The Rates and Thresholds: What You Are Actually Exposed To
The headline IHT rate is 40% on the net taxable estate above the nil-rate band. The nil-rate band is £325,000 per individual, frozen since 2009 and legislated to remain frozen until at least 2030. Inflation has been compressing the real value of that threshold for over a decade.
The Residence Nil-Rate Band and Its Limits
An additional allowance of up to £175,000 applies if you leave a main UK residence to direct descendants. This brings the potential threshold per individual to £500,000, or £1,000,000 for a married couple using both allowances and the transferable nil-rate band.
However, the residence nil-rate band tapers for estates above £2,000,000 at a rate of £1 for every £2 above that threshold. For a senior executive in oil and gas or banking with a meaningful investment portfolio, pension assets, and UK property, the £2,000,000 taper point is not a remote edge case. It is a live planning constraint.
For the current nil-rate band figures, see GOV.UK on Inheritance Tax thresholds and rates.
Why This Hits Expat Professionals in Malaysia Specifically Hard
Consider a realistic client profile: a 48-year-old British banking executive based in Kuala Lumpur, earning $300,000 per year, with a SIPP containing £400,000, £200,000 in Irish-domiciled UCITS ETFs on an offshore platform, a UK buy-to-let worth £350,000, and a life insurance policy that is not written in trust. That estate already exceeds the combined nil-rate band.
If this person spent 11 years in London before relocating to Malaysia four years ago, the tail provision means the entire global estate, including the offshore UCITS, is still in scope for UK IHT right now. The IHT exposure is not theoretical. It is approximately £430,000 at the current 40% rate, on an estate structured without any mitigation. That is money that disappears on death, with no planning required to prevent it, yet most people in this position have not acted because they assumed the old domicile rules still applied.
Planning Angles: What You Can Do
The April 2025 reform created both urgency and genuine planning opportunities. The tools available to reduce IHT exposure are well-established. Acting before the tail period expires, and before assets accumulate further, is directly beneficial.
Life Insurance Written in Trust
A life insurance policy written in trust sits outside the estate. The payout goes directly to named beneficiaries without forming part of the taxable estate and without triggering a probate delay. For an expat whose estate crosses the nil-rate band, placing a whole-of-life or term policy in a UK discretionary trust is one of the most cost-effective IHT mitigation steps available.
Without a trust wrapper, a policy payout lands in the estate, is subject to 40% IHT on the excess, and may be delayed during probate. With a trust, none of those consequences apply.
Many expats in Malaysia hold life cover through employer group schemes or existing UK policies that are not written in trust. This is a fixable problem that requires a trust deed and a letter of direction. It is not a major structural change. It is an administrative step with significant financial consequences if not completed.
Labuan Structures
For clients with significant assets outside the UK, Labuan-domiciled holding structures are worth exploring. Malaysia’s Labuan International Business and Financial Centre allows the establishment of offshore trust and foundation structures that may legitimately sit outside a UK IHT-liable estate, depending on how the structure is established and whether HMRC would treat the settlor as retaining a benefit.
This area requires proper legal and tax input. The structures are not aggressive avoidance. They are well-established, OECD-recognised arrangements used by globally mobile professionals. But the details matter. A poorly drafted Labuan trust can be challenged. A well-drafted one is robust. The line between the two requires qualified legal input.
If you have been thinking about your estate plan as part of a broader cross-border financial review, Labuan structures are a productive area to explore now, before your estate grows further.
Reviewing Domicile Formally
Domicile has not become irrelevant. It remains a factor in certain IHT contexts, particularly for spouses from different domicile backgrounds and for some pre-April 2025 planning still in effect. If you have taken deliberate steps to acquire a domicile of choice outside the UK, through consistent behaviour, formal intention, and severance of UK ties, a review by a qualified solicitor may add a parallel layer of protection.
For most expats in Malaysia, the practical focus is now the residence-based long-term UK resident test. But for those who have lived in Malaysia for many years, have significant ties here, and have genuinely shifted their settled intention away from the UK, a formal domicile of choice claim is worth reviewing alongside the residence-based planning.
Structured Gifting
The UK annual gifting exemption is £3,000 per individual. Gifts made more than seven years before death fall outside the estate entirely under the potentially exempt transfer rules. Taper relief on gifts between three and seven years before death reduces IHT from 40% progressively down to 8% in year six to seven.
For an expat in Malaysia with meaningful surplus income, a structured gifting programme started now reduces the taxable estate over a 7-year horizon. The key is to begin while health is not a concern and circumstances are stable. Waiting until the tail period has lapsed, or until the estate has grown significantly larger, is a planning failure that compounds quietly over time.
This is exactly the kind of decision that cross-border diversification planning should address: not just how your money is invested, but how your estate is structured across jurisdictions.
Frequently Asked Questions
Q: Does the new long-term UK resident test apply if I left the UK before April 2025?
A: Yes. The test is based on your total residence history, not when you departed. If you spent 10 of the last 20 tax years in the UK as of 6 April 2025, you are already a long-term UK resident for IHT purposes. The tail period runs from the date of departure, not from April 2025. Most expats who left within the last 3 to 6 years are currently inside the IHT net.
Q: What are the current UK IHT thresholds?
A: The nil-rate band is £325,000 per individual, frozen until at least 2030. An additional residence nil-rate band of up to £175,000 applies if you leave a main UK home to direct descendants, giving a combined individual threshold of £500,000. This tapers for estates above £2,000,000 at £1 per £2 above that figure. Married couples can combine allowances up to £1,000,000.
Q: Does living permanently in Malaysia remove my UK IHT exposure?
A: Over time, yes. But not immediately. If you are already a long-term UK resident, your worldwide estate remains in scope for 3 to 6 tax years after you cease UK residency, depending on how many qualifying years you accumulated. Permanent Malaysia residence helps your position year by year. It does not cancel the liability on arrival.
Q: Are my Irish-domiciled UCITS ETFs inside the UK IHT net?
A: If you are a long-term UK resident under the new test, yes. The post-April 2025 rules bring your worldwide estate into scope, including offshore investments such as Irish-domiciled UCITS funds held on international platforms. The location of assets does not determine IHT status. Your residence history does. This is one of the most misunderstood consequences of the 2025 reform.
Q: Can a Labuan trust protect assets from UK IHT?
A: Potentially, if structured correctly and if you have genuinely transferred control and benefit. HMRC will scrutinise arrangements where the settlor retains effective control or derives ongoing benefit. Professionally drafted Labuan trust structures used by internationally mobile clients are well-established. However, legal advice specific to your situation is essential before establishing any structure.
Q: I have only been in Malaysia for two years. Should I be concerned?
A: If you spent 10 or more years in the UK within the 20-year window before your move, yes. The test is backward-looking. Two years of Malaysia residence does not erase a decade of UK residence history. The tail provision applies for 3 tax years after leaving if you had 10 to 13 qualifying UK residence years. The time to plan is now, not when the tail period is already running down.
If the April 2025 IHT reform has created uncertainty about your estate exposure, the time to address it is before the tail period lapses or your estate grows further.
