Switzerland vs. the French Riviera: A Tax Comparison for Second-Home Buyers

Published 31 July 2026

Two of Europe's most coveted addresses sit less than three hours apart by car — and could not differ more in how they treat a second home.

Engadina, in the Swiss canton of Graubünden, and the Côte d'Azur, on France's Mediterranean coast, both attract the same kind of buyer: someone seeking privacy, natural beauty, and a residence among peers who value discretion as much as location. The decision between them, however, often comes down less to the property and more to the tax framework surrounding it.

Switzerland: Predictability Through Lump-Sum Taxation

Switzerland's most distinctive offering for qualifying foreign nationals is forfait fiscal — lump-sum taxation based on living expenses rather than worldwide income. For a non-working foreign resident, this can mean a fixed, negotiated annual tax figure, agreed directly with cantonal authorities, replacing the ordinary income tax return entirely.

Graubünden remains one of the cantons where this regime is still available, though eligibility depends on residency status, nationality, and — critically — not working in Switzerland. Property in Engadina itself is also subject to Switzerland's Lex Koller restrictions, which limit foreign purchases of Swiss real estate in most cases; qualifying for lump-sum tax residency is often the pathway that also unlocks the ability to hold property directly, rather than through a Swiss entity.

The appeal is certainty. Once negotiated, the tax figure is known, stable, and not tied to global income fluctuations.

The French Riviera: Wealth Tax and Capital Gains, With Treaty Relief

France taxes differently and, for most buyers, more heavily. Owning a residence on the Côte d'Azur brings a French national real estate wealth tax (IFI) if French property assets exceed €1.3 million — assessed annually on the property's value, independent of income.

Capital gains on eventual sale are taxed on a sliding scale that reduces with years of ownership, reaching full exemption from capital gains tax after 22 years (30 years for social charges). Buyers planning a shorter hold should factor this directly into their return calculations.

France's extensive double-taxation treaty network can meaningfully offset the impact for buyers already paying tax elsewhere, but the relief is treaty-specific — it depends entirely on the buyer's country of tax residence, and requires careful review before, not after, purchase.

The Real Difference: Structure, Not Just Rate

The comparison is not simply "which country taxes less." Switzerland offers a negotiated, predictable framework tied to residency; France offers a well-established ownership structure with treaty protections but ongoing wealth and capital gains exposure. The right choice depends entirely on a buyer's residency plans, existing tax domicile, holding horizon, and broader estate considerations.

This is precisely where the two geographies demand different diligence — and where mandates are won or lost on details that a general property search never surfaces.

How Orion Approaches This

Every Orion mandate in Engadina or the Côte d'Azur begins with an honest conversation about intent: is this a residence, an investment, a future domicile? The answer shapes everything that follows — the regime under negotiation, the entity (if any) used to hold the property, and the professionals brought in alongside us.

Orion does not provide tax or legal advice directly; on every mandate, we work alongside independent Swiss and French tax counsel to ensure the structure fits the client's full picture, not just the property in front of them.
