The abolition of the United Kingdom's non-dom regime in April 2025 was the largest single change to UK personal taxation in nearly two centuries. Most of the clients we now work with — families relocating personally, founders moving operating businesses, and groups consolidating offshore structures — first heard about it in passing, then in earnest, and then began to plan. This piece is for the next group: the ones still working out what it actually means.
What follows is a measured explanation of the new framework, what is and is not protected, and where the United Arab Emirates fits in for those considering their position. It is general guidance, not personal advice. The right next step is a conversation with both a UK tax advisor and a UAE corporate services practice. We provide the latter; we are not the former.
What changed in April 2025
The remittance basis of taxation — the framework that allowed long-term UK residents who were not domiciled in the UK to keep foreign income and gains outside the UK tax net — was abolished and replaced with a residence-based system.
From 6 April 2025 onward, all UK residents are taxed on their worldwide income and gains from the moment they become UK-resident. There is a transitional four-year regime for genuinely new arrivals who have been non-UK-resident for the prior ten years, but this is a doorway-only relief: it does not apply to anyone who was already in the country at the cut-off.
For the existing non-dom population — by HMRC's own count, roughly 70,000 people — the position is now substantially the same as it would have been had they always been UK-domiciled. Some specific carve-outs apply for the transition years, including a temporary repatriation facility that allowed previously-protected foreign income to be brought into the UK at a flat 12% rate during 2025–2026, rising to 15% in the year after. That facility closes entirely on 5 April 2028.
The practical question for most of our clients is not whether the rules are fair. It is whether their family's life and their business's home are best built around the new rules, or somewhere else.
What is still possible inside the UK
It is worth being clear that the UK is not a punishing tax jurisdiction by international standards. Top marginal rates of income tax remain at 45%, capital gains tax at 24%, corporate tax at 25%, and the operational framework remains competitive for primarily UK-facing businesses. For many clients with primarily UK-domiciled assets and UK-domiciled professional lives, the cost-benefit of staying is unchanged.
The clients for whom the calculation has shifted most decisively are those who:
- Hold meaningful overseas assets — operating businesses, real estate, securities portfolios, family trusts — that were previously kept entirely outside the UK tax envelope.
- Generate income from those overseas assets that they did not need to remit to the United Kingdom.
- Run operating businesses whose customers, suppliers, or growth markets sit predominantly outside the UK.
- Have flexibility about where they physically live and where the business is incorporated, and have or can establish meaningful ties in another suitable jurisdiction.
For these clients, the new framework means foreign income and gains they previously kept offshore are now taxed in the UK in the same year they arise, whether or not they ever cross into the United Kingdom. The 200-year-old structural advantage is gone.
Why the United Arab Emirates
Several jurisdictions remain attractive for tax-resident relocation. Monaco, Switzerland (under cantonal lump-sum agreements), Italy (under the substitute-tax regime for new residents), and Portugal (under its remaining non-habitual-resident framework) all have their place. Each has constraints — capital requirements, residency tests, family-presence rules, language and lifestyle adjustments.
The United Arab Emirates is the leading destination for departing UK residents and UK-incorporated operating businesses for measurable, structural reasons rather than ones of fashion:
- Zero personal income tax on residents, and zero capital gains tax. There is a 9% federal corporate tax now applied to UAE-domiciled businesses with profits above AED 375,000 per year (introduced 2023) — comfortably below the UK's 25% headline rate — but the personal envelope remains untouched.
- Long-term residency permits through the Golden Visa programme — ten-year renewable residency for property investors (AED 2 million+), salaried professionals above defined thresholds, company directors and investors, specialist categories. The visa carries family members and a wide range of employee allocations.
- A double-tax treaty with the United Kingdom that confirms primary taxing rights to the UAE on most UAE-source income for tax-resident individuals.
- Operational mature financial infrastructure. Major UK and international banks operate full retail and corporate branches. KYC and source-of-funds requirements are robust but workable for clean money with proper documentation.
- An English-speaking, internationally-served operational environment. Schools follow British, American and IB curricula. Healthcare meets European standards under JCI accreditation. Professional services are abundant. For operating businesses, the workforce is internationally mobile and the regional market is accessible from one time zone.
What the UAE is not is a place to arrive lightly. The mechanics of UK exit — Statutory Residence Test compliance, P85 filing, asset structuring, business succession, exit-tax position on substantial shareholdings — reward people who plan them with care.
The sequence that matters
Most clients we work with take six to nine months from first conversation to a fully settled life in Dubai. The sequence that has worked best, across the families and founders we have helped, looks like this:
Months minus six to minus three — the UK position
The first conversation is rarely about Dubai. It is about the UK position: where you live, where the business operates, what assets and shareholdings sit where, what year-end UK obligations apply, and what your accountant believes the optimal exit shape looks like. We do not duplicate that work. Your existing UK advisor — or one we can introduce — leads here.
Specific items to clarify in this window:
- Statutory Residence Test plan for the year of departure. The 'sufficient ties' test is more permissive than the simple day-count, but only if used deliberately.
- Capital gains realisation timing — both for personal assets and (where applicable) substantial-shareholding founders. Some assets are better sold before tax-residency leaves the UK; some after.
- UK Ltd company position. Where the operating business is moving with you, the question is redomiciliation versus subsidiary retention; where it is staying, the question is dividend extraction and ongoing UK exposure.
- UK pension and ISA position. NS&I and ISA wrappers behave differently for non-residents.
- Any UK trust structures. Most are now caught by the new rules and need careful handling.
Months minus three to zero — the UAE arrival
This is where our practice does most of its work. In parallel with your UK exit preparations we secure your Golden Visa, incorporate the UAE company vehicle (or coordinate the redomiciliation of an existing UK business), open personal and corporate bank accounts (including international banks where useful), arrange school applications for the Dubai academic year, organise homes, prepare the dependant visa structure for spouse and children, and where applicable arrange employee visa allocations for the team coming with you.
The compressed timeline is usually a single concern: do all these touchpoints have to happen sequentially, or can they run in parallel? The answer is largely the latter, with the right orchestration.
Months plus one to plus three — the settled state
P85 filed with HMRC. UK exit recorded. Emirates ID issued and residency stamped. Banking fully operational. Children in school. Household administration handed off to ongoing PRO services. Corporate tax registration completed for the UAE business. Customer contracts migrated where applicable. Your relationship with us shifts from active orchestration to ongoing advisory.
From this point onward you are a UAE tax resident with proper documentation, settled banking, an operating company if relevant, and the practical apparatus of life and business in place. The relocation is no longer something happening to you. It is simply where you live now.
What comes next
Every client's circumstances are different, and the prescriptive temptation in pieces like this one is high. Resist it. There is no formula. There is, however, a process — and a small number of practitioners across the UK and UAE who can guide you through it without missteps.
If you are weighing your position, the best thing we can offer is a thirty-minute conversation, without charge or obligation. Bring your accountant if you wish; we work alongside them, not in competition. Initial conversations are by appointment, in person at our Dubai Silicon Oasis office or by secure video call.
This article is general information about the United Kingdom non-dom transition and the United Arab Emirates' suitability as a destination for relocating individuals and businesses. It does not constitute UK or UAE tax advice, and the specifics of any individual's position can differ materially from the general framework set out above. We strongly recommend taking personal advice from a UK chartered tax advisor (for UK exit planning) and an authorised UAE corporate services practice (for the operational landing) before acting on any of the content.
