Of all the UK taxes a foreign property owner faces, Inheritance Tax is the one most often assumed to be avoidable — and the one where that assumption is most expensive. UK residential property sits within UK IHT at 40% no matter where the owner lives, and the structures that historically sheltered it were closed years ago. The April 2025 reforms changed the landscape again.
UK Inheritance Tax at 40% applies to UK situs assets on death, regardless of where the owner lives — and UK residential property is always UK situs. From 6 April 2025 the UK moved to a residence-based IHT system; domicile no longer determines what non-UK assets are caught. Long-term UK residents (broadly, UK resident in 10 of the previous 20 tax years) face IHT on their worldwide estate; non-residents face IHT only on UK situs assets. Holding UK property through an overseas company does not avoid IHT under the non-excluded overseas property rules.

The Fundamental Principle: UK Property Is Always Within UK IHT
Inheritance Tax is the UK's tax on the value of an estate on death (with some lifetime gifts also potentially caught). The fundamental principle for foreign investors is straightforward but often misunderstood:
- UK situs assets are always within UK IHT, regardless of the owner's residence, domicile, citizenship or any other connecting factor.
- UK residential property is always UK situs — it cannot be made non-UK situs by any structuring device.
- Therefore every foreign investor holding UK property has IHT exposure on that property, whether they ever visit the UK or not.
This has always been true and continues under the April 2025 regime. What changed in April 2025 is the treatment of non-UK situs assets and the basis on which worldwide assets can be caught.
What Changed on 6 April 2025
Before April 2025, IHT exposure on worldwide assets depended on domicile — broadly, the country an individual treated as their permanent home under common law. UK-domiciled or deemed-domiciled individuals faced IHT on their worldwide estate; non-domiciled individuals faced IHT only on UK assets.
From 6 April 2025, domicile is replaced as the connecting factor by residence. The new test is whether the individual is a "long-term UK resident". The change affects what non-UK situs assets are caught — but does not change the position on UK situs assets, which remain within IHT under both regimes.
The Long-Term UK Resident Test
Broadly, an individual is a long-term UK resident in a tax year if they have been UK tax resident for at least 10 of the previous 20 tax years. Key points:
- "UK tax resident" is determined by the Statutory Residence Test (SRT) — not the SDLT residence test.
- Years of residence need not be consecutive — gaps and returns count.
- The UK tax year runs 6 April to 5 April.
- Transitional provisions apply to individuals who ceased UK residence before 6 April 2025.
📌 The tail period after leaving the UK
- UK resident for 10–13 of the previous 20 years: 3-year tail.
- Each additional year of UK residence beyond 13 adds 1 year to the tail.
- UK resident for 20+ years: 10-year tail (the maximum).
A long-term resident leaving after 20 years cannot escape UK IHT on their worldwide estate for 10 years after departure.
⚠ New, complex and subject to transitional provisions
The residence-based IHT regime took effect from 6 April 2025 and is still subject to ongoing HMRC guidance and case-law development. Transitional rules apply to individuals who ceased UK residence before 6 April 2025 and were not UK domiciled on 30 October 2024. The detailed application depends on full residence history, the status of any trusts, treaty considerations and other factors. Specialist advice is essential for anyone materially affected.
How IHT Applies in Practice for Foreign Property Owners
Foreign property investors generally fall into one of three categories:
Category 1: Non-resident, never long-term UK resident
The typical foreign investor — lives in the UAE, India, Pakistan, Singapore, US, etc., visits occasionally, never lived in the UK long enough to become long-term resident. UK IHT applies to the UK property only (and other UK situs assets); worldwide assets remain outside UK IHT. The 40% rate applies above any available nil-rate band (standard £325,000; residence nil-rate band of £175,000 is rarely available for non-resident investor properties).
Category 2: Currently UK resident but not yet long-term
Individuals who moved to the UK relatively recently. UK IHT applies to UK situs assets including UK property; worldwide assets remain outside UK IHT until the long-term threshold (year 10) is reached. There is a crucial planning window between arrival and reaching long-term status — gifts of non-UK assets made before becoming long-term resident remain outside UK IHT.
Category 3: Long-term UK resident
UK tax resident for 10+ of the previous 20 years. UK IHT applies to worldwide assets; gifts of non-UK assets made while long-term resident are within scope; the position continues during the tail period after leaving.

The Non-Excluded Overseas Property Rules
One of the most important specific rules for foreign property investors is the "non-excluded overseas property" regime introduced in 2017:
- Normally, shares in an overseas company held by a non-domiciled individual would be excluded property — outside UK IHT.
- Under the 2017 rules, shares in an overseas company whose value derives directly or indirectly from UK residential property are not excluded property.
- They are deemed UK situs and are within UK IHT in the hands of the foreign owner.
- The rule also catches debt secured against UK residential property held by overseas individuals/entities.
Historically, holding UK residential property through an overseas company was a standard IHT shelter — the property was UK situs but the company shares were not. The 2017 rules closed this. The position for 2026/27 is:
| Ownership structure | UK IHT position on UK residential property |
|---|---|
| Personal ownership | Within UK IHT at 40% on death |
| UK company | Within UK IHT (you own UK situs shares in a UK company anyway) |
| Overseas company | Within UK IHT (shares treated as UK situs via the 2017 rules) |
| Trust | Complex — depends on trust structure and settlor/beneficiary residence |
In short: corporate structures alone do not shelter UK residential property from UK IHT.
Planning Techniques That Remain Relevant
The 2017 rules and April 2025 reforms closed some historic routes, but effective IHT planning remains legitimate and important. The approach has shifted from "avoid the UK situs status" to "plan around it".
Trust structures
Trusts remain a powerful succession tool. The IHT status of trust assets depends on whether the settlor is a long-term UK resident; trusts settled by a non-long-term-resident settlor with non-UK assets generally remain outside UK IHT, but UK situs assets in any trust remain within IHT regardless. Ten-year anniversary and exit charges continue to apply, and timing relative to the settlor's residence history is critical.
Debt structuring
UK residential property charged with bona fide third-party debt has its IHT value reduced by the deductible debt. The debt must be a genuine commercial liability; recent provisions restrict deductibility for connected-party debt; and mortgage debt secured on UK property held by non-residents is itself UK situs under the 2017 rules.
Life assurance funding
Where IHT exposure is unavoidable, whole-of-life assurance written in trust can provide funds to meet the liability without forcing a sale of the property. Policy proceeds written in trust fall outside the deceased's estate — most appropriate for property intended to remain in the family.
Double Tax Treaty Considerations
The UK has IHT-specific double tax treaties with a small number of countries — including India, Pakistan, the US, France, Italy, Ireland, the Netherlands, Sweden, Switzerland and South Africa. These treaties can provide relief from double IHT where the home country also imposes a death tax, credit for foreign tax paid against UK IHT, and in some cases primary taxing rights to one country only. The older treaties (notably India and Pakistan) contain particularly valuable provisions and should always be checked.
⭐ Key Takeaways
- UK residential property is always within UK IHT at 40% — wherever the owner lives.
- From April 2025, residence (not domicile) determines exposure on worldwide assets.
- "Long-term UK resident" = UK resident for 10 of the last 20 years; a 3–10 year tail follows departure.
- Overseas companies do not shelter UK property — the 2017 rules treat the shares as UK situs.
- Trusts, genuine debt, life assurance and the older IHT treaties remain effective tools.
Frequently Asked Questions
Yes, for UK situs assets. IHT at 40% applies to UK situs assets on death regardless of where the owner lives, and UK residential property is always UK situs. Every foreign owner of UK property has IHT exposure on it.
No. Under the non-excluded overseas property rules (2017), shares in an overseas company whose value derives from UK residential property are treated as UK situs and remain within UK IHT. Corporate structures alone do not shelter UK property.
The UK replaced domicile with residence as the connecting factor for worldwide assets. The new test is the "long-term UK resident" test — broadly UK resident for 10 of the previous 20 years. UK situs assets remain within IHT under both old and new regimes.
UK tax resident (under the SRT) for at least 10 of the previous 20 tax years. Long-term residents face IHT on their worldwide estate and remain in scope for a tail period of 3 to 10 years after leaving the UK, depending on how long they were resident.
