The Regime She Couldn't Have Used

Tina Turner spent the better part of three decades living in Küsnacht, a village on Lake Zurich, and the last ten years of it as a Swiss citizen. Most retellings of her move credit her with using Switzerland's "lump-sum taxation" regime — a genuinely remarkable deal available to certain wealthy foreigners there. There's a problem with that story: on the facts, she almost certainly never had access to it.

Why the Math Doesn't Work

Lump-sum taxation lets a qualifying foreign resident pay tax based on their cost of living in Switzerland — typically five to seven times their annual rent — instead of declaring worldwide income at standard progressive rates. It's available in cantons including Vaud, Geneva and Ticino. It has never been available in Zurich, which abolished it by referendum in February 2009, with the change taking effect in 2010, years into Turner's residency at a Zurich-canton address. The regime is also open only to foreign nationals who aren't employed in Switzerland, and Turner became a Swiss citizen in April 2013, the same day she gave up her US passport. That would have ended her eligibility even if the canton had offered it in the first place.

Nothing in the public record shows her ever using the regime. What is documented is simpler, and honestly more interesting: a woman who moved to Switzerland for a relationship in the mid-1990s, stayed for nearly three decades, and eventually chose full naturalisation rather than simply residing there.

What the Regime Actually Offers Someone Who Can Use It

For a foreign resident with genuinely large passive income and no Swiss employment, the numbers can be striking. Someone earning $50 million a year from investments abroad, taxed on an assessed cost-of-living base rather than that income, can end up paying a small fraction of what standard rates would produce. Someone with more modest income often finds standard taxation cheaper — the regime rewards scale, not just wealth.

• Vaud, Geneva, Ticino
  Lump-sum taxation available?: Yes

• Valais, Berne, Fribourg, Grisons, Neuchâtel, Jura
  Lump-sum taxation available?: Yes

• Zurich
  Lump-sum taxation available?: No — abolished 2010

• Basel-Stadt, Basel-Land
  Lump-sum taxation available?: No

• Schaffhausen
  Lump-sum taxation available?: No

• Appenzell Ausserrhoden
  Lump-sum taxation available?: No

The minimum tax base typically runs CHF 400,000 to over CHF 1 million — the assessed figure the tax is calculated against, not the tax itself.

Naturalisation Closes the Door

There's a structural reason Turner's citizenship matters beyond the sentimental. Lump-sum taxation exists only for non-working foreign nationals. Take the passport, and you've removed yourself from the pool eligible for the regime, wherever in Switzerland you live. It's a trade long-term foreign residents there weigh carefully before making it — the simplicity is real, but so is the exposure once citizenship changes the terms.

Turner's actual story reads less like a structuring case and more like an ordinary long residency that ended in full naturalisation — its own kind of commitment, and one that most HNW arrangements are specifically designed to avoid ever requiring.

Where the Same Logic Applies Elsewhere

Switzerland isn't the only place offering favourable treatment for genuinely relocated wealthy foreigners, and for readers who don't want to live in Küsnacht, a few other regimes run on comparable logic.

• Italy
  Regime: Flat tax on foreign-source income
  Current terms: €300,000/year for residency taken up from 1 January 2026; €200,000/year grandfathered for those already resident by end-2025

• Greece
  Regime: Non-dom flat tax
  Current terms: €100,000/year on foreign income

• Cyprus
  Regime: Non-dom regime
  Current terms: 17-year exemption on foreign dividends and interest

• Malta
  Regime: Global Residence Programme
  Current terms: Flat rate on remitted foreign income

• Portugal
  Regime: Post-2024 NHR reform
  Current terms: Materially less favourable than the pre-2024 regime

Every one of these trades a fixed, predictable tax bill for genuine physical relocation, and every one has eligibility rules narrow enough that which regime you qualify for matters more than which one sounds best. That's the question worth answering before choosing a country — and it's the first thing we work through with clients weighing a move like this.

Getting the Fit Right

A lump-sum or flat-tax assessment starts with your income sources, your intended canton or country, and your citizenship plans — because, as Turner's case shows, citizenship can quietly close a door that residency alone left open. Bring those three things to a scoping call and you'll leave knowing which regimes you can actually use, not just which ones make good headlines.
