Let me set you a scene: You’re worth a few million pounds (stay with me), sipping your morning Earl Grey – life’s not so bad, you say to yourself. Then you open the newspaper to see yet another tax hike targeting your hard earned wealth. What’s your immediate reaction? If you’re like 16,500 other UK millionaires, you’re probably googling “best countries for wealthy expats” right about now.
Here’s the big kicker — Britain is about to lose more millionaires than any other country on the planet in 2025. Yes, that’s right, we’ve officially dethroned China from the top spot of the wealth exodus leaderboard (what an accolade). So why are the UK’s richest residents trading their London townhouses for Dubai penthouses? Let’s dive into this financial brain drain that’s got everyone fussing.
The Great British Wealth Escape: By the Numbers
According to Henley & Partners’ latest Wealth Migration Report, the UK is haemorrhaging millionaires faster than you can say “capital gains tax.” We’re talking about 16,500 high-net-worth individuals (HNWIs) — that’s people with over $1 million (approximately £740,500) in liquid assets — saying cheerio to Britain this year.
To put that in perspective:
- That’s more than double China’s projected loss of 7,800 millionaires
- It’s a massive jump from last year’s forecast of 9,500 departures
- For the first time in a decade, a European country leads this unfortunate ranking
Dr. Juerg Steffen, Henley & Partners’ CEO, called it a “pivotal moment” — and that clearly means, not the good kind. “This isn’t just about changes to the tax regime,” he explained. “It reflects a deepening perception among the wealthy that greater opportunity, freedom, and stability lie elsewhere.”
In plain English? The UK’s rich aren’t just worried about their tax bills — they’re questioning whether Britain’s still the place to grow their wealth. Ah.
Where Are All the Millionaires Going?
While Britain’s weeping wealth, other countries are rolling out the red carpet (and probably some tax incentives). The winners in this global game of millionaire musical chairs?
The United Arab Emirates is the biggest winner, expecting to gain 9,800 millionaires. Makes sense — zero income tax, year-round sunshine, and a business-friendly environment? Sign me up. Lovely jubbly.
The United States comes in second (surprise surprise), attracting 7,500 wealthy individuals. Despite its own tax complexities, America’s entrepreneurial spirit and vast market opportunities continue to lure the ultra-rich. The American Dream never died after all.
Italy rounds out the top three with 3,600 incoming millionaires. Between the pasta, the weather, and some attractive tax schemes for new residents, la dolce vita is looking pretty tasty for wealthy expats. My personal choice, if I was a millionaire that is…
The Tax Hikes That Broke the Camel’s Back
So, what fueled the flame on this mass exodus? The Autumn Budget dropped like a tonne of bricks on wealthy Brits, featuring:
Capital Gains Tax Increases
The government hiked capital gains tax rates, making it more expensive to cash out investments. For someone sitting on millions in gains, that’s a bulky bill.
The End of Non-Dom Status
Arguably the most controversial move? Abolishing the centuries-old non-dom regime. This ‘special’ tax status allowed UK residents to avoid paying tax on overseas income and gains. Its demise has wealthy foreigners scrambling for the exits on the double.
Inheritance Tax on Foreign Trusts
Adding insult to injury, the government also ended the inheritance tax exemption for foreign-held trusts. Some studies suggest over a quarter of non-doms could leave because of these twin changes alone.
VAT on Private School Fees
Even education got hit with new taxes, as private school fees now attract VAT. For wealthy families already considering a move, this could have been the nail in the coffin.
High-profile departures include City grandee Richard Gnodde and Aston Villa co-owner Nassef Sawiris — and they’re just the ones making headlines.
The Real Cost of Losing Millionaires
Here’s what politicians might be missing (wait… another thing?!): when millionaires pop off, they take more than just their bank accounts. David Lesperance from Lesperance & Associates puts it bluntly: these “Golden Geese” contribute way more than just income tax.
Think about it logically, love them or loath them:
- They employ people (from household staff to business employees)
- They spend big on consumer goods and services
- They invest in local businesses and startups
- They donate to charities and cultural institutions
- They pay VAT, property taxes, and countless other levies
When a millionaire leaves, that economic activity goes with them. It’s like removing a Jenga block from the economy — pull out enough, and things start getting as waddly as a Mallard.
Is There a Way Back?
The Treasury seems to be having second thoughts (indecision?! Shocking…). Chatter about the Commons is they’re considering dialling back some of the more aggressive tax changes, particularly around foreign trusts. But is it too little, too late?
Meanwhile, Nigel Farage’s Reform UK has thrown a wildcard into the mix with their “Robin Hood” tax proposal. The scheme would charge wealthy foreigners £250,000 for a decade of UK tax residency without touching their foreign assets. The proceeds? Straight into the pockets of Britain’s lowest-paid workers. It’s controversial, sure, but at least someone’s thinking outside the box.
The Bottom Line
The UK’s millionaire exodus isn’t just about tax rates — it’s a symptom of deeper concerns about Britain’s economic direction. When your wealthiest residents are voting with their feet (and their private jets), it’s fair to say it’s time to ask some hard questions about competitiveness and growth.
For the millionaires themselves, the calculation is simple: why pay more tax in a stagnant economy when sunny, tax-friendly shores beckon? For the UK, the challenge is figuring out how to balance the need for tax revenue, with remaining an attractive destination for global wealth.
One thing’s certain — this wealth migration trend is reshaping the global economy, and Britain needs to act fast if it wants to stop the bleeding. Otherwise, we might find ourselves asking: who’s going to pay for all those public services when the people footing the biggest bills have moved to Dubai? Potential future article title? We hope not.

FAQ: UK Millionaire Migration 2025
Q1: What qualifies someone as a “millionaire” in this context?
In the Henley & Partners report, a millionaire is defined as someone with over $1 million (approximately £740,500) in liquid investable assets. This doesn’t include property or other illiquid investments — we’re talking cash, stocks, bonds, and other easily accessible wealth.
Q2: Why is the UAE such a popular destination for relocating millionaires?
The UAE offers a compelling package: zero income tax, a stable political environment, world-class infrastructure, and a strategic location between Europe and Asia. Plus, Dubai and Abu Dhabi have invested heavily in creating luxury lifestyles and business opportunities that appeal to the ultra-wealthy.
Q3: How does the UK’s millionaire exodus compare historically?
This is unprecedented. The UK has never led the world in millionaire outflows since tracking began over a decade ago. The jump from 9,500 projected departures in 2024 to 16,500 in 2025 represents a 74% increase — that’s not normal fluctuation, that’s a stampede.
Q4: Could these tax changes actually reduce overall tax revenue?
It’s possible. This is the classic Laffer Curve dilemma — raise tax rates too high, and you might collect less total revenue as wealthy individuals leave or find ways to avoid taxes. The departing millionaires take their spending, investments, and future tax contributions with them.
Q5: Is there any chance these millionaires might return to the UK?
History shows that once wealthy individuals establish new tax residencies, they rarely return. However, if the UK significantly improves its tax competitiveness and economic growth prospects, it could attract new millionaires to replace those who’ve left. The question is whether policymakers are willing to make those changes.
