Relocating to Dubai: The HMRC Pitfalls That UAE Advisers Must Understand

The flow of high-net-worth individuals from the UK to Dubai has accelerated dramatically since the announcement of the Finance Act 2025 non-dom reforms. The UAE's absence of personal income tax, capital gains tax, and inheritance tax — combined with its modern infrastructure, international connectivity, and business-friendly regulatory environment — has made Dubai the single most popular destination for UK tax emigrants. HMRC is acutely aware of this trend and has responded with increased compliance resources dedicated to scrutinising UK-to-Dubai relocations. The risk, from HMRC's perspective, is that individuals claim to have left the UK and become non-resident while in reality maintaining their centre of life in the UK — flying to Dubai periodically to maintain the appearance of residence there while continuing to live, work, and socialise primarily in the UK. The consequence of HMRC successfully challenging a claim to non-UK residence is severe: the individual remains subject to UK income tax and capital gains tax on their worldwide income and gains, potentially for multiple tax years. The penalty regime for careless or deliberate errors in self-assessment returns adds a further financial burden, and in egregious cases, HMRC may pursue criminal prosecution for tax fraud. For UAE-based private wealth managers, law firms, accounting firms, and family offices advising clients who have relocated or are planning to relocate from the UK, understanding the HMRC risk profile is essential. The advice must be realistic about the behavioural changes required to achieve non-UK residence and the ongoing compliance obligations that persist after departure.

The Statutory Residence Test in Schedule 45 to Finance Act 2013 is the mechanism by which UK residence is determined, and its application to Dubai relocations contains several traps that UAE advisers must understand. The SRT operates through automatic overseas tests (which, if met, result in non-UK residence), automatic UK tests (which, if met, result in UK residence), and a sufficient ties test that weighs UK connections against UK days. The third automatic overseas test — the most commonly relied upon by Dubai relocators — requires the individual to have worked sufficient hours overseas throughout the tax year, with no significant break from overseas work. An individual who relocates to Dubai and takes up full-time employment or establishes a genuine business there will typically satisfy this test, provided they spend fewer than 91 days in the UK during the tax year and work in the UK for fewer than 31 days. However, the definition of 'working' for SRT purposes is technical and narrowly construed. Time spent on incidental duties, travel between engagements, and administrative activities may not count as 'working' for the purposes of the overseas work test. HMRC scrutinises the working pattern carefully, and individuals who claim to work full-time in Dubai but cannot demonstrate a genuine and substantive role face a significant risk of challenge. The sufficient ties test is the fallback mechanism for individuals who do not satisfy any of the automatic tests. For a 'leaver' — an individual who was UK-resident in one or more of the three preceding tax years — the thresholds are more stringent than for an 'arriver'. A leaver with four UK ties can spend no more than 15 days in the UK without becoming UK-resident. The ties include the family tie, the accommodation tie, the work tie, the 90-day tie, and the country tie, and each requires careful management in the context of a Dubai relocation. UAE advisers should ensure that clients maintain contemporaneous records of their UK days, their working patterns, and their UK connections, and should recommend that specialist UK tax advice is obtained before and during the relocation process.

Dubai's free zones — including the Dubai International Financial Centre (DIFC), Dubai Multi Commodities Centre (DMCC), and Jebel Ali Free Zone — offer a range of benefits to businesses, including simplified company formation, 100 per cent foreign ownership, and regulatory frameworks tailored to specific sectors. The introduction of UAE corporate tax in 2023 (at a rate of 9 per cent) includes a 0 per cent rate for qualifying free zone entities that earn qualifying income, maintaining the tax advantage of free zone structures. For UK-resident individuals who control free zone companies, or UK-headed corporate groups with free zone subsidiaries, the UK anti-avoidance provisions apply in full. The CFC rules in Part 9A of TIOPA 2010 may apply to attribute the profits of a free zone company to its UK-resident corporate controller, particularly where the free zone company earns passive income or income derived from arrangements with UK-connected parties. For individual controllers, the transfer of assets abroad provisions in sections 714-751 of ITA 2007 may attribute the income of a free zone company to a UK-resident individual who has the power to enjoy that income. The closely held company provisions in section 3 of TCGA 1992 may similarly attribute capital gains of the free zone company to its UK-resident participators. UAE-based corporate service providers and law firms establishing free zone structures for clients with UK connections should ensure that the UK tax implications are fully analysed. A structure that works well from a UAE regulatory and tax perspective may nonetheless give rise to UK tax liabilities for the individuals or companies that control it. Daniel Feingold can advise on the UK tax treatment of free zone structures and the application of the relevant anti-avoidance provisions.

One of the most significant — and most frequently overlooked — UK tax consequences of relocating to Dubai is the continuing exposure to UK inheritance tax. The UAE does not impose inheritance tax, and many clients assume that by leaving the UK, they have left the UK IHT net. This assumption is incorrect for the vast majority of Dubai relocators. For individuals who are UK-domiciled (whether by origin or by choice), UK IHT applies to their worldwide assets regardless of where they are resident. Domicile is a common law concept that is notoriously difficult to change — it requires not merely physical relocation but the formation of a genuine and settled intention to reside permanently or indefinitely in the new jurisdiction. Individuals who relocate to Dubai while maintaining a UK passport, UK family connections, UK property, or an intention to return to the UK at some point may find it impossible to demonstrate that they have acquired a domicile of choice in the UAE. The Finance Act 2025 reforms have introduced extended deemed domicile provisions for inheritance tax purposes. Under these rules, an individual who has been UK-resident for at least fifteen of the previous twenty tax years is treated as deemed domiciled in the UK for IHT purposes, and this deemed domicile status continues for a specified period after the individual ceases to be UK-resident. The effect is that worldwide assets remain within the UK IHT charge even after the individual has relocated to Dubai and ceased to be UK-resident under the SRT. UAE private wealth managers and family offices advising clients with UK IHT exposure should ensure that appropriate planning measures are considered, including the use of excluded property trusts (subject to the Finance Act 2025 conditions), life insurance arrangements, and the timing of asset disposals and restructuring relative to the deemed domicile tail period. Daniel Feingold has extensive experience of IHT planning for individuals departing the UK and can provide definitive advice on the deemed domicile rules.

The temporary non-residence rules in section 10A of the Taxation of Chargeable Gains Act 1992 are designed to prevent individuals from leaving the UK for a short period, realising capital gains while non-resident, and then returning to the UK. The rules apply where an individual who has been UK-resident for at least four of the seven tax years preceding the year of departure returns to the UK within five complete tax years. Gains realised during the period of temporary non-residence are treated as arising in the year of return and are charged to UK CGT. For individuals relocating to Dubai, the temporary non-residence rules create a five-year window during which caution is required. If the individual intends to remain in Dubai indefinitely, the rules will not bite — but if there is any possibility of a return to the UK within five years, the tax planning must take account of the potential charge. This is particularly relevant for individuals who relocate to Dubai on an initial basis with the intention of 'trying it out' before committing permanently. The rules apply to gains on assets held at the date of departure and to certain other categories of gain, including gains attributed to the individual under the closely held company provisions and gains on assets acquired during the period of non-residence where the asset derives its value from UK-situs property. The computational rules are complex, particularly where the individual has made a rebasing election under the Finance Act 2025 transitional provisions. The split-year treatment provisions in Part 3 of Schedule 45 to Finance Act 2013 may apply to the year of departure and the year of return, dividing the tax year into a UK part and an overseas part. The interaction between the split-year rules and the temporary non-residence provisions requires careful analysis. UAE-based advisers should ensure that clients understand the five-year temporary non-residence period and plan their asset disposals accordingly.
