You may have left Britain 10, 20 or 30 years ago. Your home, business interests and investment portfolio may now be centred in Singapore, Hong Kong, Dubai, Australia or North America. Inheritance tax on UK property for non-residents can remain a significant issue, even after someone has lived outside Britain for 10, 20 or 30 years. You may also have established that you are not a long-term UK resident under the inheritance tax rules introduced in April 2025.

That can make a profound difference to the treatment of your overseas wealth. It does not, however, make the question of inheritance tax on UK property for non-residents disappear.

For many families, the most important part of the new regime begins after non-LTR status is established. Overseas assets may generally sit outside the UK inheritance tax net, but a London flat, buy-to-let portfolio or land in Britain can remain exposed. The family may have left the UK. The assets have not.

Residence history determines how far the UK can reach; asset location determines what remains within reach.

The April 2025 Change Did Not Make UK Property Exempt

From 6 April 2025, the UK replaced the former domicile and deemed-domicile framework for inheritance tax with a residence-based test. HM Revenue & Customs says an individual will broadly be a long-term UK resident when they have been UK tax resident for at least 10 of the previous 20 tax years. A person who leaves can also retain LTR status for between three and 10 tax years, depending on their residence history.

That tail matters. Someone who has recently left Britain should not assume they became non-LTR on departure, while someone abroad for decades should not rely on “expatriate” as a tax status. The result turns on the relevant tax years and residence record.

Once a person is genuinely non-LTR, their non-UK assets will generally be outside the territorial scope of UK inheritance tax, subject to important exceptions and special rules. UK-situated assets can remain in scope. HMRC’s own guidance for people based abroad gives UK property and UK bank accounts as examples of assets on which inheritance tax may still be payable.

In other words, non-LTR status can narrow the UK tax net. It does not remove the net from Britain itself.

A £5.75 Million Estate Can Still Leave a £530,000 UK Question

Consider a simplified example. A widowed British expatriate has lived in Asia for more than 20 years and is assumed, for this illustration, to be non-LTR. Her worldwide wealth is £5.75 million:

• an overseas home worth £2.1 million;
• an international investment portfolio worth £1.7 million;
• overseas cash and deposits of £300,000; and
• UK rental properties worth £1.65 million.

The first number most families see is £5.75 million. Under a residence-based system, that is not necessarily the correct starting point for the UK calculation. If the individual is non-LTR and the overseas assets qualify as excluded property, attention may instead turn to the £1.65 million situated in the UK.

Assume, solely to expose the scale of the issue, that the properties are owned outright, there are no deductible debts, spouse or charity exemptions, lifetime gifts or other reliefs, and one £325,000 nil-rate band is available. No residence nil-rate band is included because the example concerns rental properties and does not assume a qualifying home passes to direct descendants.

The illustration is then:

• UK rental property: £1,650,000
• Less nil-rate band: £325,000
• Illustrative taxable amount: £1,325,000
• Inheritance tax at 40 per cent: £530,000

The actual liability could be materially higher or lower. Ownership, transferred allowances, debt, reliefs, gifts, the will and the facts at death all matter. The £530,000 is not a forecast or advice. It shows that a family can have most of its wealth outside the UK tax net and still leave a six-figure UK liability.

The standard nil-rate band remains £325,000 and the ordinary inheritance tax rate remains 40 per cent. Budget 2025 policy fixes the nil-rate band at that level through 2030–31. For long-held property that continues to appreciate, a frozen allowance can steadily enlarge the exposed amount without the owner buying another asset or changing how they live.

Why “I Live Abroad” Is the Wrong First Answer

The conversation about inheritance tax on UK property for non-residents often starts with location: “I have lived overseas for 25 years.” That fact is relevant, but it answers only the residence part of the analysis.

A useful review separates three questions:

1. What is the individual’s LTR status at the relevant time?
2. Which assets are legally situated in the UK or treated as UK assets?
3. What exemptions, reliefs, debts and allowances are actually available?

The second question can catch more than a personally owned house. HMRC confirms that the rules can look through certain foreign companies and partnerships whose value is attributable to UK residential property. They can also reach relevant property loans and certain supporting collateral.

An offshore company is therefore not an invisibility cloak. HMRC gives the example of a non-UK resident who owns a Jersey company whose only asset is a London flat. The foreign shares are treated as within the UK inheritance tax scope to the extent their value derives from the UK residence.

Land Registry titles may therefore be only part of the picture. Personal ownership, company interests, partnerships, trusts, loans and security arrangements may all need to be mapped.

Excluded Property Trusts and UK Residential Property

Trusts are another source of misplaced confidence. Under the post-April 2025 rules, property situated outside the UK and held in certain trusts can be excluded property while the settlor is not a long-term UK resident. HMRC also warns that a change in the settlor’s status can have separate trust-charge consequences.

The distinction is the location of the underlying value. The rules on an excluded property trust and UK residential property are specifically designed to prevent UK homes from being taken outside inheritance tax merely by interposing an overseas company, partnership or trust. UK residential property held indirectly can remain within scope to the extent the foreign interest derives its value from that property.

This is why “the property is in an offshore trust” tells a family little on its own. Relevant facts include when the settlement was created, who added assets, the settlor’s LTR status, what the trust owns, how UK property is held and whether the settlor can still benefit.

Trusts can serve legitimate succession and governance purposes, but carry their own tax regimes. There is no universal offshore trust that converts UK residential property into excluded property.

Why Gifting the Property Is Not a One-Line Solution

The next instinct is often to transfer the property to the children. An outright gift to an individual can become exempt if the donor survives for seven years, but that summary conceals several important qualifications.

If the donor dies within seven years, the gift can remain relevant to the inheritance tax calculation. A transfer of property can also create capital gains tax, financing, legal and family-governance consequences. If the asset is a home and the donor gives it away but continues to occupy or benefit from it, the gift-with-reservation rules may treat the property as remaining in the donor’s estate.

HMRC defines a gift with reservation as one in which the donor gives property away but continues to benefit from it. Where that retained benefit exists at death, the gifted property can be deemed part of the estate. The seven-year rule is therefore not a simple countdown that cures every transfer.

None of this means a gift, sale, trust or ownership change is necessarily right or wrong. It means the tax result cannot safely be inferred from the change of name on a title deed. The analysis has to take place before the transaction.

Does the UK Property Still Justify Its Place?

There is a broader portfolio question hidden inside the tax question. Many expatriates did not build a deliberate UK property allocation. They accumulated one.

A former family home was retained after a move. A flat was bought for a child. Rental properties remained because selling felt unnecessary. Twenty years later, those decisions may amount to concentrated exposure to one property market, currency and tax system.

The correct response is not automatically to sell. It is to measure what is being retained. That means considering current market value, net rental income after costs and UK tax, financing, management burden, unrealised capital gain, currency exposure, liquidity and the potential inheritance tax cost if the asset remains in the estate.

A property delivering a modest net yield may still be valuable for diversification, family use or appreciation. But past success and present suitability are different questions. For HNW families, the opportunity cost and loss of flexibility can be as important as the tax.

The Liability Arrives Before the Inheritance

Inheritance tax is generally settled from the estate by the personal representatives. A UK property liability can therefore affect how and when beneficiaries receive wealth, while requiring valuations, probate work and liquidity.

Property can create a particular mismatch: the estate owns something valuable but does not necessarily hold the cash required to settle the tax and administration costs. HMRC permits inheritance tax attributable to certain property to be paid by instalments in some circumstances, but interest and eligibility rules apply. Instalments address timing; they do not make the liability disappear.

The next generation may also be international. A child overseas may inherit a UK rental business they do not want, alongside reporting and tax considerations at home. Planning should consider not only what the parent owns, but what the beneficiary can realistically receive.

The Review Is About Exposure, Not a Predetermined Solution

For a non-LTR family, the most productive starting point is a clear inventory rather than a product or structure. The review needs to establish:

• the individual’s UK tax-residence history and any LTR tail;
• every UK asset and indirectly held UK property interest;
• current ownership, debt and security arrangements;
• existing wills, trusts and lifetime transfers;
• which allowances, exemptions or reliefs may be available;
• where the beneficiaries live and what they are intended to receive; and
• whether the present structure still reflects the family’s objectives.

This does not predetermine a recommendation. The conclusion may be to retain the property unchanged. It may reveal that an old will no longer coordinates with the ownership. It may identify a liquidity gap, an outdated valuation or a structure that requires specialist legal and tax review.

The value lies in replacing an assumption with a documented position.

Leaving the UK Did Not Move the Asset

The new residence-based regime has made non-LTR status exceptionally important for internationally mobile families. It can place qualifying overseas wealth outside the scope of UK inheritance tax. That protection should not be confused with immunity for wealth that remains connected to Britain.

The central question is no longer simply, “Have I lived abroad long enough?” It is: “Which parts of my estate can the UK still tax, and how large could that exposure be?”

For an expatriate with £5.75 million of worldwide wealth, the relevant UK estate might be £1.65 million rather than the entire amount. That is a major distinction. An illustrative £530,000 liability is still a major family issue.

If you have lived outside the UK for years but retain a home, rental portfolio, land or an indirect interest in UK residential property, it may be time to establish what the April 2025 rules mean for your estate—not to assume a solution, but to understand the problem accurately.
