Britain lost a record 16,500 millionaires in a single year. The UAE gained more than any country on earth. This is why the wealth map is being redrawn in 2026, and how families make the move to Dubai legally, with XILLION Group.
For most of the last century, wealth moved toward the great capitals of the West. London, Paris and Geneva were where fortunes were kept, grown and passed on. In 2026 that assumption no longer holds. The wealthiest families in the United Kingdom and across Europe are relocating, and a striking number of them are landing in Dubai.
The numbers are not subtle. In 2025 the United Kingdom recorded a net loss of 16,500 dollar millionaires, the largest outflow of high-net-worth individuals any country has posted since Henley & Partners began tracking migration a decade ago. In the same year the United Arab Emirates attracted a net 9,800 millionaires, the most of any nation on the planet, more than two thousand ahead of the United States in second place. This is not a rumour or a marketing line. It is a measured, sustained shift, and it is accelerating.
At XILLION Group we have watched this play out from the inside. Every week our team speaks with founders, family offices and private clients in London, Oslo, Paris and Mumbai who have made the same decision and want the same thing: a clean, correct and permanent move to the UAE. This guide explains why the exodus is happening, why Dubai keeps winning, and exactly how a move is done properly. Where the mechanics get detailed, we point you to our companion guides, the British Millionaire's Guide to Moving Wealth to Dubai and the private client playbook, Moving Your Wealth to Dubai.
The migration is often described as people chasing sunshine and zero tax. That is too simple. What is really happening is a series of tax and policy decisions across Europe that have made staying expensive and moving rational. The pattern repeats from one country to the next.
The single biggest driver is Britain. In 2025 the United Kingdom abolished the non-domicile regime that had, for two hundred years, allowed internationally mobile residents to keep their foreign income and gains outside the UK tax net. In its place came a residence-based system that pulls worldwide income into scope and, most importantly for families with legacies to protect, exposes worldwide assets to inheritance tax at 40%. For a family whose wealth sits in global businesses, funds and property, that is not a marginal adjustment. It is a fundamental change to how much of an estate survives to the next generation. By Henley's own count, British citizens now make up close to half of all relocation applicants, up from around 8% in 2018.
Norway offers the clearest cautionary tale. Its annual wealth tax, charged on net assets whether or not they produce cash, combined with a tightened exit tax, prompted some of the country's most prominent industrialists to leave. When founders relocate, their companies, their capital and their future taxes tend to follow. Norway's experience has become the reference point that finance ministers across Europe now argue about.
France has openly worried about a wealth-tax race to the bottom in the wake of Britain's exodus. Germany, Spain and others are weighing similar measures, and the European Union has begun examining coordinated exit taxes designed to make leaving harder. For a high-net-worth family, the mere debate is enough. Capital does not wait to be taxed. It moves early, while the rules are still favourable and the exit is still clean. The common thread is simple: wherever governments treat private wealth as a target rather than a partner, that wealth quietly relocates to where it is welcome.
Wealthy families have many places they could go. Singapore, Switzerland, Monaco and Portugal all compete for them. Yet the UAE, and Dubai in particular, keeps finishing first. In the 2026 wealth-migration competitiveness ranking, the UAE scored 85.3 out of 100, ahead of Singapore, New Zealand and the United Kingdom. The reasons are practical, not sentimental.
Put together, the UAE offers something Europe no longer does: a place where building and keeping wealth is treated as a good thing. That is why UAE-based relocation enquiries rose 41% heading into 2026, and why our own calls at XILLION have never been busier.
This is the part that separates a durable move from an expensive mistake. The UAE has no personal income tax, but a relocation does not become tax efficient simply by buying a plane ticket or a Dubai apartment. A clean move has two sides, and both have to be done properly.
First, you establish genuine residency in the UAE. That means real presence, a residency visa, an Emirates ID, and usually a home and a business or investment here. Substance matters. Tax authorities look at where you actually live, work and keep your centre of life, not just where you hold a card.
Second, you exit your home tax net cleanly. Every country has its own rules for when you stop being tax resident, and some, as we have seen, are adding exit taxes and long tails of continued exposure. Timing, documentation and sequence matter enormously. Done well, the move is fully compliant and defensible. Done carelessly, a family can find itself taxed in two places at once.
A word of honesty. Requirements change, and every family's position is different. Eligibility, tax residency and exit rules depend on your specific circumstances and on current regulations in both countries. XILLION Group handles the UAE side of the move end to end, and works alongside your home-country tax and legal advisers so that nothing is assumed and nothing is left exposed. We build structures to last, not to look good on a brochure.
XILLION Group is a Dubai-based corporate services firm built for exactly this. We take a family or a founder from the first quiet enquiry to a fully licensed, banked and resident structure in the UAE, and we do most of it remotely, before you ever board a flight.
1. The strategy call. We start by understanding your assets, your home-country position and your goals. You speak with our team directly, not a call centre, and you leave the call knowing the right route, the real cost and the honest timeline.
2. The company. Most relocations are anchored by a UAE company, because it provides a licence, a Golden Visa pathway and access to corporate banking. We advise on the right structure for your activity, a free zone company or a Dubai mainland company, and handle the entire incorporation and government paperwork.
3. Residency and the Golden Visa. We process your UAE Golden Visa, entry permit, medical, Emirates ID and family sponsorship, so your residency is real, documented and long term. This is the backbone of your new tax position.
4. Banking, done by people who know banks. This is where most relocations stall, and where XILLION is different. Our founder, Imran Mirza, spent seven years inside UAE banks before building XILLION, on top of more than a decade in company formation. We know what compliance teams look for, and how to open personal and corporate accounts that actually work for internationally mobile wealth.
5. Ongoing compliance and PRO. Once you are set up, we keep you compliant, handle renewals, and manage corporate tax registration and government liaison, so your structure stays clean year after year.
After years of doing this, the same avoidable errors come up again and again. We flag them so you do not repeat them.
