For a UHNWI choosing a low-tax European base, the shortlist usually comes down to three: Andorra, Monaco and Switzerland. They are not interchangeable. One is the world’s most expensive market with no income tax, one is genuinely restrictive about who can buy, and one is the accessible middle option that asks you to actually move in. This guide compares the three on the questions that decide it: tax, cost of entry, who can buy, and lifestyle.

Tax: the headline comparison
Monaco has the purest headline: no personal income tax for residents, in place since 1869, with the notable exception of French nationals, who remain taxed by France. Andorra is not zero but is low and simple: income tax topping out at 10%, and no wealth, inheritance or gift tax. Switzerland is the most nuanced, taxed federally and by canton, with cantonal wealth taxes, though certain wealthy foreigners can negotiate a lump-sum arrangement, which varies by canton.
The clean way to read it: Monaco is zero income tax at the highest cost of entry; Andorra is very low tax at a far lower cost; Switzerland is moderate and cantonally variable but with a lump-sum route for some. None removes home-country obligations unless you genuinely move and break prior tax residence. Our Monaco guides cover the Monaco position in full.
| Tax | Andorra | Monaco | Switzerland |
|---|---|---|---|
| Income tax | 10% top rate | None (except French nationals) | Federal + cantonal; lump-sum for some |
| Wealth tax | None | None | Cantonal wealth tax applies |
| Inheritance tax | None | Territorial, by relationship | Cantonal; often relieved for direct heirs |
Cost of entry
This is where the three separate most sharply. Monaco is the world’s most expensive residential market, so the cost of establishing a base there is in a class of its own. Andorra is a fraction of that price per square metre while still offering the low-tax lifestyle, which is much of its appeal. Switzerland’s prime alpine and lakeside markets are expensive but sit between the two.
Residency thresholds differ too. Andorra’s passive residency now turns on EUR 1,000,000 invested, or EUR 400,000 via the Housing Fund, plus a non-refundable deposit. Monaco’s residency rests on securing accommodation and a substantial bank relationship, by convention rather than a fixed legal figure. Switzerland’s routes vary by canton and by whether you take the lump-sum arrangement. The gap in raw cost between Andorra and Monaco is the single biggest practical difference.
Who can actually buy?
Here is a distinction most comparisons miss. Switzerland restricts foreign purchase of residential property under Lex Koller, with permit quotas set by canton, so a foreign buyer cannot simply acquire what they want where they want. Andorra caps foreign individuals at one home or two units and taxes foreign capital on entry. Monaco, by contrast, places no nationality restriction on who may buy.
So on openness to the foreign buyer, Monaco is the most permissive on ownership though the most expensive, Andorra is capped but accessible, and Switzerland is the most restrictive by law. A buyer whose plan depends on acquiring a specific Swiss property should confirm the Lex Koller position for that canton and property before anything else.
Lifestyle and access
Monaco offers the glamour, the marina, the events calendar and a location on the Riviera minutes from Nice airport. Switzerland offers world-class infrastructure, schooling and alpine or lakeside living with excellent air links. Andorra offers the Pyrenees, the largest ski domain in the range, low crime, mature private banking, and a quieter, more private life, at the cost of one real friction: it has no airport of its own.
That access point matters. Andorra is reached by road from Barcelona or Toulouse, or by helicopter, where Monaco and the Swiss hubs sit beside international airports. For a buyer who values a private-jet arrival to the door, it is a genuine mark against Andorra that has to be weighed against its lower cost and simple low tax.
Which base suits whom?
Monaco suits the buyer who wants zero income tax and Riviera prestige and can meet the cost. Switzerland suits the buyer who wants infrastructure, schooling and central-European access and can navigate Lex Koller and cantonal tax. Andorra suits the buyer who wants a genuinely low tax bill, a far lower cost of entry, and a private mountain life, and who is willing to accept the access trade-off and actually move in for the residency to work.
None is a paper exercise. All three reward a genuine relocation and none delivers its benefit to someone who buys but lives mostly elsewhere. The right answer depends on budget, on how much the airport matters, and on whether you can buy what you want where you want, which is where Switzerland’s restrictions and Andorra’s cap come in.
| Cost and rights | Andorra | Monaco | Switzerland |
|---|---|---|---|
| Cost of entry | Low, a fraction of Monaco | Highest, world’s dearest | High prime markets |
| Foreign buying | Capped: one home or two units | No nationality restriction | Restricted (Lex Koller) |
| Residency basis | EUR 1M / EUR 400k Housing Fund | Accommodation + bank relationship | Varies by canton |
Key takeaways
- Monaco: zero income tax, highest cost, no nationality restriction on buyers.
- Andorra: 10% top income tax, no wealth/inheritance/gift tax, far lower cost, foreign owners capped at one home or two units.
- Switzerland: cantonally variable tax with a lump-sum route for some, but Lex Koller restricts foreign buying.
- Andorra’s access is the trade-off: no airport, reached by road or helicopter, where Monaco and Swiss hubs sit by airports.
- All three reward a genuine move, not a paper residence.
Frequently asked questions
Is Andorra or Monaco better for tax?
Monaco has no personal income tax (except for French nationals); Andorra’s income tax tops out at 10%. Both have no wealth or inheritance tax. Monaco is purer on income tax but far more expensive to enter; Andorra is very low tax at a fraction of the cost.
Can foreigners buy property in Switzerland?
Only within limits. Switzerland restricts foreign purchase of residential property under Lex Koller, with permit quotas set by canton. Confirm the position for the specific canton and property before proceeding.
Which is cheapest to establish a base in?
Andorra, by a wide margin on property cost per square metre, compared with Monaco, the world’s most expensive market, and Switzerland’s expensive prime markets. Andorra’s residency threshold is EUR 1,000,000, or EUR 400,000 via the Housing Fund.
Does Andorra have a wealth tax like Switzerland?
No. Andorra levies no wealth tax, no inheritance tax and no gift tax. Switzerland applies cantonal wealth taxes, though some wealthy foreigners negotiate a lump-sum arrangement that varies by canton.
What is the biggest downside of Andorra versus Monaco or Switzerland?
Access. Andorra has no airport and is reached by road from Barcelona or Toulouse, or by helicopter, where Monaco and the Swiss hubs sit beside international airports. It is offset by Andorra’s much lower cost and simple low tax.
Do any of these remove my home-country tax?
Only if you genuinely relocate and break prior tax residence. None of the three delivers its benefit to someone who buys a property but continues to live mostly in their home country. Take cross-border advice before moving.
