Inheritance tax on a Dubai property: the UK-UAE double bind

Your Dubai property answers to two death regimes at once

A Dubai property owned by a UK-connected person is subject to two entirely separate systems on death, and the trouble is that each is usually planned for as if the other did not exist. The United Kingdom decides how much tax the estate pays on the property. The United Arab Emirates decides who actually inherits it. These are different questions answered by different laws, and a plan that settles one leaves the other exactly where it was.

The difficulty with an inheritance question is that the person best placed to fix it is, by definition, not in the room when it matters. The double bind on a Dubai property tends to surface at the worst possible moment: a family dealing with a death also discovers that the London solicitor's will does a great deal of work in Woking and very little in Dubai, and that the apartment everyone assumed would simply pass to the surviving spouse is subject to a distribution nobody chose.

The purpose of this article is to bring that discovery forward by some years, to the point where it is still a planning problem rather than a bereavement one.

This is the estate-planning corner of the wider position set out in the hub on Dubai property and the UK owner, and it is deliberately distinct from two neighbouring questions. It is not the UK home a family keeps behind, which is dealt with in selling UK property after moving to Dubai, and it is not the general architecture of a cross-border will, which is set out in DIFC and ADGM wills and the cross-border estate. It is the narrower and sharper case of a single asset, the Dubai property, sitting in the crosshairs of both a UK tax and a foreign succession regime at the same time.

The UK charge 40% if you are a long-term resident

Whether the UK taxes the Dubai property on death turns on one status: whether the owner is a long-term UK resident. Since 6 April 2025 UK inheritance tax has been residence-based rather than domicile-based, and the pivotal concept is the long-term resident. A person who has been UK resident for at least 10 of the previous 20 tax years is a long-term resident, and a long-term resident is within UK inheritance tax on their worldwide estate. For such a person the Dubai property is simply part of the estate, taxed at 40% above the available nil-rate band like any other asset, wherever in the world it sits.

The residence-based rule is the successor to the old domicile test, and it changed the question from "where is this person domiciled" to "how long have they been resident". The mechanics of the transition, and the way the charge now attaches to years of residence rather than to the slippery concept of domicile, are set out in the analysis of the non-dom abolition and the UAE inheritance-tax tail. The practical headline for a Dubai owner is blunt: if you have lived in the UK for a decade or more, the Dubai apartment is in your UK estate, and the 40% charge reaches it. The tax-free country the property sits in does not shelter it, because the charge is on the person's estate, not on the asset's location.

Why the Dubai property behaves differently from the London house

The Dubai property differs from a UK home in one decisive respect: it can leave the UK inheritance-tax net, whereas the UK home never can. This is the analytical heart of the matter, and it is worth taking slowly, because it is where most families get the wrong intuition. A UK home is UK-situated property, and UK-situated property is within UK inheritance tax regardless of the owner's residence or domicile; there is no version of the facts in which it drops out. A Dubai property is foreign-situated, and foreign property is within UK inheritance tax only while its owner is a long-term resident.

The consequence is a genuine difference in the shape of the exposure over time. While the owner is a long-term resident, both properties are in the net. But once the owner ceases to be a long-term resident, having left the UK and run down the long-term-resident tail, the Dubai property becomes excluded property and falls out of UK inheritance tax, while the London house stays in it forever. The length of that tail, which runs from three to ten years depending on how long the person was resident, is the subject of the long-term resident inheritance-tax tail. The point of principle is that the Dubai property's UK exposure is temporary and residence-dependent, whereas the UK home's is permanent and situs-dependent. A family that treats the two identically, in either direction, plans badly: they either assume the Dubai flat is stuck in the UK net like the house when it need not be, or they assume the house will drop out like the flat when it cannot.

The UAE side, who inherits is decided in Dubai, not in your English will

The second regime does not care about tax at all; it decides who inherits the property, and for a Dubai asset that decision is made under UAE law, not by an English will. This is the half of the problem that even well-advised families miss, because they reason from the UK estate outwards and assume the will they signed in London governs everything they own. For assets situated in Dubai, and for real estate in particular, that assumption is unsafe.

Since Federal Decree-Law No. 41 of 2022 came into force, a non-Muslim who dies without a will recognised in the UAE is subject to a civil default distribution rather than automatic Sharia division: broadly, half of the estate passes to the surviving spouse and the remainder is shared equally among the children. That is already a surprise to many owners, because it is not what their English will says and not what they assumed.

The concrete version is the one that lands hardest: a widow who took for granted that the Dubai apartment was simply hers may find that, under the default, half of it belongs to the children, including minor children, with all the practical difficulty that brings. And for real property specifically, where no recognised will is in place, Sharia principles can still enter the analysis, because UAE law has historically treated immovable property located in the Emirates as governed by local law. The detail of the framework, the civil default, and the recognised-will routes are set out in DIFC and ADGM wills and the cross-border estate.

The mechanism behind the surprise is simple to state. An English will is a UK document; a Dubai court applies UAE law to a Dubai asset; and unless there is a will the UAE recognises, the court applies its own default, not the wishes recorded in Woking. The estate then faces not only a distribution the deceased did not choose but the delay and cost of resolving a foreign succession without the right document in place, at exactly the moment the family can least absorb it.

The registered will fixes the succession half, not the tax half

A will registered through the DIFC Wills Service or the Abu Dhabi ADJD process fixes the succession problem, and only the succession problem. A non-Muslim can register a will that directs their UAE assets, including a Dubai property, to chosen beneficiaries, displacing the civil default and removing the risk that local principles apply to the real estate. This is the correct and well-established route, and for anyone holding property in Dubai it is close to essential: it is what turns "who inherits the flat" from a question decided by a Dubai court under default rules into one decided by the owner.

But it is important to be precise about what the will does and does not do, because owners frequently over-read it. A registered will controls the destination of the property; it has no effect whatsoever on the UK inheritance-tax charge. The 40% remains due on the value of the Dubai property in a long-term resident's estate whether the asset passes under a DIFC will or under the UAE default, because the tax is charged on the estate's value, not on the route of devolution. A family that registers a DIFC will and considers the matter closed has solved the "who" and left the "how much" untouched. The will is necessary; it is not sufficient.

The two regimes on one asset

Set side by side, the two regimes answer different questions, turn on different facts, and are managed by different instruments. The table below is the whole problem on a single page.

Reading across the two rows is the point. The left-hand regime is a question of money and is answered by residence and structuring; the right-hand regime is a question of people and is answered by a registered will. Neither column touches the other. Register the will and the tax is unchanged; plan the tax and the succession is unchanged. The asset is the only thing the two regimes have in common, which is exactly why it needs to be planned from both sides at once.

Two problems, two plans

Because the regimes are independent, a UK-connected owner of a Dubai property needs two plans, and the most common failure is to build one and assume it covers the field. The succession plan is the registered will: it decides who inherits and keeps the estate out of a Dubai court's default. The tax plan is separate and turns on residence and structure: how long the owner has been and intends to remain a long-term resident, whether the long-term-resident tail can be run down so the property leaves the UK net, how spousal and other exemptions apply, and whether any lifetime steps are appropriate. One plan without the other leaves half the exposure live.

There is a further trap in trying to solve the tax half with a structure, because the obvious move usually backfires. An owner who reaches for a company to hold the Dubai property, hoping to change the inheritance-tax analysis, generally finds they have created a 9% UAE corporate-tax charge on the rent and gains, as set out in the property SPV and the 9% corporate tax, and a controlled-foreign-company or transfer-of-assets analysis on the UK side, without necessarily removing the property from the estate at all. The wrapper that looks like an inheritance-tax answer is often a tax problem in its own right. The reliable levers on the UK side are residence and the tail, not a hastily chosen holding vehicle, and the reliable lever on the UAE side is the will. For owners who want the ownership structure and the cross-border position built correctly from the outset, rather than corrected later, our company setup in Dubai for UK residents service handles the vehicle, the substance, and the UK-side analysis together.

What a UK-connected owner of a Dubai property should do

The sensible sequence is to treat the "who" and the "how much" as two tasks and to complete both. First, register a will recognised in the UAE, through the DIFC or ADJD, directing the Dubai property to the intended beneficiaries, so that the succession is governed by the owner's choice rather than by a default distribution and a foreign court. Second, establish the inheritance-tax position: whether the owner is a long-term resident, when that status would end on a departure, and what the estate's exposure to the 40% charge is in the meantime, before deciding whether any structuring or lifetime planning is worthwhile.

Held in that order, the two plans reinforce each other: the will removes the succession uncertainty immediately, and the tax analysis frames the longer decision about residence and structure. The owner who does only the first has decided who inherits a property that is still fully taxed; the owner who does only the second has reduced a tax on an asset that may pass to the wrong people.

The Dubai property is the rare asset that genuinely requires both a UK adviser and a UAE will to be safe, and the reason is the one this article began with. It answers to two death regimes, and a plan that speaks to only one of them is not a plan. It is half of one.

Frequently asked questions

Is my Dubai property subject to UK inheritance tax?

If you are a long-term UK resident, yes. Since 6 April 2025 UK inheritance tax has been residence-based, and a person who has been UK resident for at least 10 of the last 20 tax years is a long-term resident, taxed at 40% on their worldwide estate above the nil-rate band. The Dubai property is part of that estate. The fact that the UAE charges no inheritance tax does not remove the UK charge, because the tax is imposed on the estate of the person, not on the location of the asset.

Does my English will cover my Dubai property?

Not reliably. A Dubai property is dealt with by a Dubai court under UAE law, and unless there is a will the UAE recognises, the court applies its own default distribution rather than your English will. For non-Muslims that default is broadly half to the spouse and the remainder equally among the children, and for real estate local principles can still be relevant. The safe course is to register a will through the DIFC Wills Service or the Abu Dhabi ADJD process to direct the Dubai property specifically.

Who inherits my Dubai property if I die without a UAE will?

Without a will recognised in the UAE, a default distribution applies under Federal Decree-Law No. 41 of 2022: broadly, half of the estate passes to the surviving spouse and the remainder is shared equally among the children. This is often not what the owner intended or what their English will says, and it can leave a surviving spouse owning only part of a property they assumed was wholly theirs. A registered DIFC or ADJD will replaces that default with the owner's own choice of beneficiaries.

Does a DIFC will reduce the UK inheritance tax?

No. A DIFC or ADJD will decides who inherits the Dubai property; it has no effect on the UK inheritance-tax charge. The 40% is due on the value of the property in a long-term resident's estate regardless of how the asset passes. The will and the tax are two separate matters: the will solves the succession question, and the tax has to be addressed separately through the owner's residence position and any appropriate planning. Registering a will and assuming the tax is dealt with is a common and costly error.

How is a Dubai property different from my UK home for inheritance tax?

A UK home is UK-situated and is always within UK inheritance tax, regardless of your residence, so it never leaves the net. A Dubai property is foreign-situated, so it is within UK inheritance tax only while you are a long-term resident; once you have left the UK and the long-term-resident tail has run, the Dubai property becomes excluded property and drops out, while the UK home does not. The two assets therefore behave differently over time, and should not be planned as if they were the same.

Can I take my Dubai property out of UK inheritance tax?

Potentially, through residence rather than through a structure. Because the property is foreign-situated, it leaves the UK net once you cease to be a long-term resident, which happens after you have become non-resident and the long-term-resident tail, of between three and ten years, has run. Holding the property through a company is usually not the answer, because it can create a 9% UAE corporate-tax charge and a UK controlled-foreign-company analysis without reliably removing the asset from your estate. The dependable lever is your residence position over time.

What happens to the property while there are minor children involved?

The default distribution can be particularly difficult where there are minor children, because a share of the property passes to them by operation of law, and dealing with a minor's interest in real estate brings its own guardianship and administrative complications in the UAE. This is one of the strongest practical reasons to register a will: it lets the owner direct the property to a surviving spouse, or into an arrangement they have chosen, rather than leaving a fractional interest to be administered on behalf of children under a default the family did not design.

Do I need both a UAE will and UK tax advice?

For a Dubai property owned by a UK-connected person, yes, and that is the central point. The UAE will governs who inherits the asset; UK advice governs how much tax the estate pays on it. Neither addresses the other, so a UK-connected owner who wants the position genuinely secure needs both: a registered DIFC or ADJD will for the succession, and an inheritance-tax analysis of their long-term-resident status and options for the tax. Doing only one leaves half the exposure unmanaged.

A Dubai property is the asset where the corridor is at its most exacting, because it is the one place two death regimes meet on a single title. The UK taxes the estate; the UAE decides the heirs; and the instruments that answer each are different and do not overlap. Plan for both and the property passes as intended, taxed at a figure you understood in advance. Plan for one and you have solved half a problem, which on death is indistinguishable from solving none of it.

The Dubai property is not simply an asset the family owns abroad. It is an asset that answers to two laws, and it has to be told what to do by both...
