Six Weeks, One Application

In 2012, as French president François Hollande pushed a proposed 75% top tax rate, LVMH chairman Bernard Arnault quietly applied for Belgian citizenship. When the news broke, French commentators called him a traitor to the nation whose luxury industry he personifies. Within weeks, he withdrew the application, saying it had nothing to do with taxes.

There's no ambiguity about what actually happened here, and no criminal or civil proceeding attached to any of it. Arnault applied for a second citizenship, using an entirely lawful process available to any EU resident who qualifies. He didn't get very far into it before the political cost became obvious, and he pulled out. That's the whole story. What makes it worth studying isn't the law — the law never really came into it — it's the six weeks of public reaction that followed.

The Backdrop

France's context at the time was genuinely severe. The country had a broad wealth tax, the ISF, later narrowed to real estate only and renamed the IFI in 2017. Combined with high income tax and social charges, French high-net-worth individuals faced a heavier, more continuous tax burden than most of their European peers, year after year, regardless of whether their wealth generated any income at all. Hollande's 75% proposal, aimed at income over €1 million, was the sharpest edge of that pressure, and it made international headlines well beyond France.

Belgium, an easy hour or two away by car or train, offered a genuinely different regime: no general wealth tax, and favourable — often 0% — treatment of capital gains on privately held shares. It's also partly French-speaking, physically adjacent, and inside the EU, which means the actual act of moving requires no visa, no permission, nothing beyond establishing genuine residence. French emigration to Belgium has a long history among designers, entrepreneurs and entertainers precisely because the practical friction is so low.

Why He Withdrew

The backlash wasn't legal. It was reputational, and it was fast. Arnault clarified publicly that he intended to keep his French tax residency and denied any tax motivation, framing the citizenship application as personal and family-related rather than financial. None of that fully contained the story — for a period, "Arnault the traitor" was genuine tabloid material in a country where LVMH's brands are treated as something close to national assets, and the optics were damaging enough to the company that the application simply wasn't worth the trouble it caused.

That's the lesson worth sitting with, and it applies well beyond Arnault's tax bracket: for anyone with a public profile or a business that depends on a domestic customer base, a relocation decision carries costs that have nothing to do with tax law. Reputational risk isn't a footnote to the planning. For a sufficiently visible person, it can be the deciding factor.

What French High-Net-Worth Individuals Actually Do

Most French residents looking to reduce ongoing tax exposure don't apply for a second citizenship at all — moving tax residency doesn't require one, and the paths in practice differ mainly in language, distance, and regime.

• Belgium
  What it offers: No wealth tax; often 0% CGT on private shares; French-speaking; close
  Trade-off: Moderate political sensitivity if high-profile

• Switzerland
  What it offers: Lump-sum taxation where available; French-speaking cantons; high prestige
  Trade-off: Higher cost of living, stricter qualification

• UK (pre-2025 non-dom regime)
  What it offers: English-language global hub, since replaced
  Trade-off: No longer available in its old form

• Portugal (pre-2024 NHR)
  What it offers: Mediterranean lifestyle, English widely spoken
  Trade-off: Original NHR programme has since closed to new entrants

• UAE
  What it offers: 0% personal tax; growing French community; warm climate
  Trade-off: Cultural and lifestyle shift

• Monaco
  What it offers: French-speaking; 0% personal tax
  Trade-off: Not available to French nationals under the France–Monaco treaty

The Broader Reality

Inside the EU, physical movement is legally trivial — no visa, no quota, no approval needed. What isn't trivial is doing it properly: genuine physical relocation, severing home-country ties in substance rather than on paper, establishing real ties in the destination, and handling any departure obligations correctly, including France's exit tax on unrealised gains where it applies. None of that is where Arnault's episode ran into trouble. He never got far enough into the process for any of it to be tested.

The political sensitivity of a high-profile move stays real in France, Germany and a handful of other high-tax European countries, in a way it simply doesn't for someone without a public name attached to a national brand. That's worth knowing before you start, not after a newspaper finds out.

The Practical Takeaway

Arnault's mistake wasn't legal. It was public. The mechanics of a European relocation are straightforward for almost anyone who qualifies; the part that actually requires judgment is doing it quietly enough that it never becomes a story in the first place. If you're weighing a move inside Europe, a scoping call covers both halves — the residency mechanics and the discretion around them.
