Owning French Property as an American: What Happens on Inheritance?

For most owners, moving abroad eventually shifts which country has the strongest claim on their estate. For American citizens, it doesn't — not entirely. The United States taxes its citizens on inheritance regardless of where they live, which makes the France–US situation structurally different from most other cross-border cases.

For Americans owning property on the Riviera, understanding this distinction — and how the two countries divide the rest — is worth doing before, not after, a transfer becomes necessary.

Citizenship, Not Just Domicile, Triggers US Tax

France and the United States are connected by a bilateral convention signed in 1978 and substantially revised by a protocol in 2004. Unlike most French tax treaties, which turn primarily on domicile, this one applies to US persons on two separate bases: domicile in the US, or American citizenship — even for citizens who have lived abroad for decades and have no other tie to the US.

The 2004 protocol also added a specific anti-avoidance provision: Americans who give up their citizenship for tax reasons remain within reach of US domestic law for ten years following expatriation. This is a narrow rule aimed at a specific situation, not something that applies to ordinary long-term expatriates.

How Domicile Is Determined for Everyone Else

For the France side of the analysis, and for non-citizen family members, domicile is established under each country's own domestic rules first. On the US side, domicile for estate and gift tax purposes is a subjective, fact-based question — distinct from the residence test used for US income tax — built around a person's intentions and ties: visa filings, tax return positions, length of residence, the location of business interests, club and community affiliations, and similar indicators. Where a genuine conflict arises between the two countries, the treaty falls back on a hierarchy: permanent home, then closest personal ties, then habitual residence, then nationality, then mutual agreement between the two administrations. Which side of that line a specific person falls on is not something a general article can settle.

How the Treaty Allocates Each Asset

Real estate is taxed where it's situated — and since 2004, this has explicitly extended to shares in companies whose value mainly consists of French real estate, closing what had previously been a more ambiguous area. Assets tied to a permanent establishment or fixed base are taxed where that establishment sits. Tangible movable property is generally taxed where it's located, except items reserved for an owner's personal use, which instead follow their domicile. Everything else — company shares generally, cash, receivables, and most other intangible assets — is taxed exclusively where the owner was domiciled.

The 2004 Protocol Changed the Method for France-Domiciled Owners

This is the detail that matters most for an American who has settled in France. Before 2004, assets taxable in the US were effectively kept outside French taxation, with France only using their value to set the applicable rate on the rest. The 2004 protocol replaced this with a credit method: France now taxes the entire worldwide estate of a France-domiciled person, American or not, and any US tax paid on US assets is credited against the French tax bill.

For an American who has genuinely settled in France, this means the French estate — villa, French accounts, everything — is assessed as a whole under French rules, with US tax on US-situated assets offset rather than the US assets escaping French scope entirely.

Where the owner remains domiciled in the US instead, France taxes only the assets actually allocated to it under the treaty, but calculates the rate on those assets using the value of the full worldwide estate — the reverse of the France-domiciled scenario.

A Simple Example

Consider an American citizen who has lived in France for over a decade, owns a property near Antibes, and holds US brokerage accounts and a home in Florida. If they're domiciled in France under the treaty, the French property and the Florida home are both assessed under French rules as part of one worldwide estate, with any US estate tax on the Florida home credited against the French tax on that same asset. Their US citizenship doesn't change this outcome for French purposes — but it does mean the US retains an independent claim on their worldwide estate regardless of where they live, with a credit available for the French tax paid.

Why This Matters When Buying Property

US estate tax operates on its own separate track — a federal system with a substantial lifetime exemption, layered in some cases with state-level rules that vary by year and jurisdiction. Combined with the France side of the analysis, this makes the ownership structure chosen at purchase, and where relevant the timing and form of any US expatriation, worth examining well before a transfer is on the horizon.
