Thousands of British families hold their French holiday home not in their own names but through an English trust: a family trust set up in London decades ago, a will trust created when a parent died, or a lifetime settlement meant to protect children from a future sale. For years this arrangement sat quietly in the background while the family paid the familiar French bills — the taxe foncière (the annual land and buildings tax) and the taxe d’habitation (the housing tax now kept on second homes) — and thought no more about it. Then a letter arrives from the French tax office, or the notaire (the French public officer who alone can transfer property) asks an unexpected question on a sale, and the family discovers that France has its own complete tax system for trusts, with its own annual tax, its own declarations and its own fines.
This guide explains that system in plain English, with every French term defined when it first appears. It covers the annual tax of 3% of the property’s market value that France charges on foreign entities holding French property, the exemption that British trustees can usually claim since Brexit, the two trustee declarations that must be filed in France, what happens for French succession purposes when the settlor (the person who put assets into the trust) or a beneficiary dies, and the exact procedure for challenging a bill you consider wrong. It is written for British readers, in UK spelling, with references to the French statutes you can check yourself on Légifrance (the official French legal database) and to official British guidance where the two systems meet.
I. What France charges every year when a UK trust stands behind a French house
A. Received a 3% bill on the villa: who pays the annual tax and who escapes it
France imposes an annual tax equal to 3% of the market value — the vénale value, meaning the price the property would fetch on the open market — of French immovable property held, directly or indirectly, by foreign legal entities. The tax is laid down by Article 990 D of the Code général des impôts (the CGI, the French general tax code), and its scope is deliberately wide: it catches companies, trusts and any foreign entity interposed between the ultimate individuals and the French bricks and mortar. The logic is simple and openly stated. France cannot always see through an offshore structure to tax the individuals behind it, so it taxes the structure itself each year on the value of the French property, unless the structure agrees to transparency.
For a British family this means the starting point is uncomfortable. An English discretionary trust holding a house in the Dordogne, a Jersey trust holding a Paris flat, or a Guernsey company held itself by a family trust, all fall in principle within the charge. The tax is assessed year by year on the value at 1 January, it applies even where the property is simply enjoyed by the family and produces no rent, and it sits on top of everything else: the taxe foncière remains due, the taxe d’habitation on second homes remains due, and the impôt sur la fortune immobilière (the IFI, the French tax on real-estate wealth above 1.3 million euros) may also apply to the individuals behind the structure. A bill at 3% of a 800,000 euro house is 24,000 euros every year, so understanding the escape route is not optional.
The escape route is Article 990 E of the CGI, which exempts entities that disclose to the French tax administration the identity of their ultimate owners. In practice the exemption works through two doors. The first door is the treaty door: entities established in a state that has concluded with France a treaty containing an administrative assistance clause against fraud and evasion are exempt provided the trustees disclose the settlors, deemed settlors and beneficiaries. The United Kingdom and France are bound by the France–United Kingdom double tax convention signed in London on 19 June 2008, as amended, which contains exactly such assistance machinery, and that treaty survived Brexit unchanged because it is a bilateral convention independent of European Union membership. British trustees can therefore walk through the treaty door, on condition that they actually file the disclosure France asks for. The second door is the declaration door used by entities outside any useful treaty: full annual disclosure of the French assets and the persons behind them. Since Brexit, British trusts use the first door, but the condition is real — the exemption is lost if the disclosure is missing, late or incomplete, and the 3% assessment then follows automatically.
Three practical points decide most cases. First, identify precisely what holds the property on the French side: the service de publicité foncière (the French land registry, which records all transfers of immovable property) shows the legal owner, and where that owner is a foreign company or a trustee, the tax office treats the structure as within the charge until transparency is proved. Second, check the chain: where a UK trust holds the shares of a foreign company that itself owns the French house, each link must be disclosed, because an undisclosed intermediate company can destroy the exemption even where the trust itself has filed. Third, remember that the exemption must be renewed in effect each year through the filings described below; a disclosure made once in 2019 does not protect the 2026 assessment. The detailed payment and filing mechanics sit in Article 990 F of the CGI, and trustees who discover an old undisclosed structure should regularise before the tax office writes, because voluntary disclosure leads to the exemption while an assessment once raised must be fought through the formal challenge procedure.
British readers sometimes ask what changed at Brexit for this tax. The honest answer is that the 3% machinery itself did not change, but the context did. Before Brexit, many British-held structures relied informally on European administrative cooperation and on French offices treating British trusts as familiar neighbours; after Brexit, exchanges of information run through the bilateral treaty and through the OECD common reporting standard rather than through European Union directives, and French offices ask British trustees for formal proof of disclosure where they once asked for little. Nothing in the statute penalises British trusts for being British, but everything in daily practice rewards trustees who file early, file completely and keep stamped proof of every filing.
B. The two declarations your trustees must file in France, and the fines for silence
Alongside the 3% tax, France created a standalone reporting regime for trusts that applies whether or not any French tax is ultimately due. The cornerstone is Article 1649 AB of the CGI, which obliges the trustee (the administrateur of the trust, the person who manages the trust assets under the trust deed) to declare the trust itself to the French tax administration. Two different declarations exist and they must not be confused. The event declaration reports the creation, modification or extinction of the trust: when a new trust acquires French property, when trustees change, when a beneficiary is added or removed, when the trust deed is amended, and when the trust ends, the trustee must tell the French administration within a short deadline running from the event. The annual declaration reports the content: the market value of the trust’s French assets, the rights held, and the identity of settlors, trustees and beneficiaries, so that the administration can test the 3% exemption, the wealth tax and the succession position.
The form used for both exercises is known in practice as form 2181, filed with the tax office for non-residents, and trustees should file through a French-speaking professional because the form demands French legal categories that English trust concepts do not map onto neatly: the usufruit (the right to use and take income from property for life), the nue-propriété (the bare ownership that remains), and the distinction between capital and income beneficiaries all have to be rendered correctly. British trustees should also note the parallel obligation in the United Kingdom: most UK express trusts must register on HM Revenue and Customs’ Trust Registration Service, and useful background in English is published by the British government in its guidance on trusts and taxes. Registration in London does not replace declaration in Paris — the two systems do not exchange trustee filings automatically for this purpose — but a trust that is properly registered at home finds it far easier to produce the coherent paperwork the French office expects.
Silence is punished severely, and this is where British families suffer the most painful surprises. Article 1736 of the CGI sets the penalty regime for reporting failures, and for trusts the fines are fixed sums that apply per trust and can repeat: a trustee who files nothing can face a fine running to five figures for each undeclared trust, on top of the 3% assessment itself and on top of late-payment interest. These fines strike the trustee personally in the first instance, with recovery possible against trust assets according to the trust deed, which is why professional trust companies in Jersey, Guernsey and London now treat the French filings as a standard disbursement rather than an optional extra. Lay trustees — typically two family members appointed decades ago — often have no idea they are exposed, and the first they learn of it is a mise en demeure (a formal demand letter) in French giving them weeks to comply.
The compliance calendar that keeps a British trust safe can be stated simply. First, on any event — death of a settlor, appointment of a new trustee, addition of a beneficiary, amendment of the deed, purchase or sale of the French property — file the event declaration immediately and keep the receipt. Second, each year, file the annual declaration covering the position at 1 January and use that same filing as the disclosure supporting the 990 E exemption from the 3% tax, so that one coherent set of papers does double duty. Third, keep everything for at least six years: trust deeds with sworn translations, death certificates, valuations of the French property by a French agent, proof of posting and office receipts. Fourth, where the trustees hold bank accounts outside France used for the French property, remember that French-resident settlors and beneficiaries must themselves declare foreign accounts on form 3916 under Article 1649 A of the CGI; the trustee’s filings do not discharge the individual’s own obligations. Trustees who inherit an old non-compliant structure should take advice before filing, because a badly drafted catch-up declaration can concede points — residence, valuation date, identity of deemed settlors — that a carefully prepared one would have protected.
II. Death, residence and double tax: keeping the trust alive without paying twice
A. When the settlor or a beneficiary dies: French succession, English wills and the reserved share
The death of the settlor is the moment when the French trust regime bites hardest, and British families should prepare for it while everyone is alive. For French succession purposes, assets placed in a trust are treated as part of the deceased’s estate to the extent of their rights, under Article 792-0 bis of the CGI, introduced to give France a complete answer to foreign trusts. The territorial reach of French succession tax is set by Article 750 ter of the CGI: French immovable property is always taxable in France wherever the deceased lived, and where the deceased was French-resident, worldwide assets including trust interests can be caught. Concretely, when a British-domiciled settlor who settled a French house into a trust dies in Kent, France taxes the French house in the succession; when a British expatriate long resident in France dies holding an interest in a UK trust that owns French property, France may tax more widely, with relief for foreign tax under the treaty where the conditions are met.
Two further French rules surprise English lawyers. The first is the réserve héréditaire (the reserved share: the fraction of the estate that must by law pass to the deceased’s children, which the deceased cannot give away by will or gift). It is rooted in Article 912 of the Code civil (the French civil code), and it applies to successions governed by French law regardless of clever trust drafting in London. A trust deed that leaves everything to the surviving spouse and nothing to the children may work perfectly for English assets yet fail for the French house if French law governs the succession. The second is the European Succession Regulation No 650/2012, whose text is published on EUR-Lex, the official European Union law database: it lets a person choose the law of their nationality to govern their whole succession, so a British national can elect English law in their will to escape the reserved share, but the election must be express, valid under the Regulation, and coordinated with the trust, because assets already settled in trust pass under the trust deed, not under the will. The United Kingdom did not opt into that Regulation, which adds a conflict-of-laws wrinkle that a Franco-British file must address head-on rather than ignore.
Tax residence threads through all of this. France defines its tax residents in Article 4 B of the CGI — home in France, principal place of sojourn, professional activity in France, or centre of economic interests in France — and each alternative suffices on its own. A beneficiary who moves into the trust-owned house permanently becomes French-resident under the first branch and then taxable in France on worldwide income, while a settlor who merely holidays there does not. Residence also drives the reporting: a French-resident beneficiary must declare the trust and its accounts personally, while a non-resident beneficiary is generally visible to France only through the trustee’s filings and through French-source income. Families should therefore map residence person by person, year by year, and never assume that because the trust is English, its people are invisible to the French computer.
On death, the practical sequence for the French house runs as follows. First, the notaire in charge of the French succession asks for the trust deed, a sworn French translation, the death certificate with apostille (the international authentication stamp), and proof of the trustee filings; without these, the file stalls and the property cannot be sold or transferred. Second, the succession tax return must reflect the trust interest at its 1 January market value with a consistent valuation method, because the tax office compares the return with the trustee’s annual declarations and investigates gaps. Third, where British inheritance tax is also charged — for example on a UK-domiciled settlor’s worldwide estate — the family claims relief in one state for tax paid in the other under the double tax convention’s relief provisions, keeping both assessments and both receipts until the relief is granted. Fourth, where children consider that the reserved share has been infringed, the claim must be brought promptly before the French court, with the trust deed and valuations as exhibits, because delay weakens both negotiation and litigation. None of this requires abandoning the trust; it requires administering it as a Franco-British instrument rather than as a purely English one.
B. Your bill looks wrong: challenge deadlines, evidence and the regularisation route
British trustees most often meet the French system through an assessment they did not expect: a 3% bill for years when they believed the treaty exemption applied, a fixed fine for a declaration they never knew existed, or a succession demand valuing the house far above its worth. Every one of these can be challenged, but French tax challenges run on rails — procedure first, merits second — and the rails are set by the Livre des procédures fiscales (the LPF, the French tax procedure code). The master rule is the prior claim: under Article L.190 of the LPF, the taxpayer must first file a réclamation contentieuse (a formal written claim to the tax administration) before any court will listen, and under Article R.190-1 of the LPF that claim must in the standard case reach the office by 31 December of the second year following the year of the assessment. Miss that date and the substance of the complaint no longer matters; the claim is time-barred. The mirror rule protects the administration’s own time limits: under Article L.169 of the LPF, the office must generally assess within three years, so a 3% bill raised four years late for a filed and transparent trust can be attacked on limitation alone.
A winning file has a fixed anatomy that British trustees should follow exactly. First, pay or formally request a stay: the claim does not automatically suspend collection, so accompany the réclamation with a demande de sursis de paiement (a request to suspend payment pending the outcome) where the statute allows it, and always pay any part of the bill that is admittedly due, because partial payment strengthens credibility. Second, plead exemption before valuation: attach the treaty-disclosure filings proving the 990 E exemption for each year assessed, the trust deed extracts identifying settlors and beneficiaries, and the receipts for the 1649 AB declarations; if the exemption holds, the valuation debate disappears. Third, plead valuation in the alternative: if any charge survives, contest the market value with a French agent’s appraisal at 1 January of each year, comparable sales in the commune, and evidence of defects, tenancies or planning constraints that depress value — the tax office values property, not families, and it negotiates on paper. Fourth, plead limitation and procedure: check the date of each assessment against L.169, check that the bill names the correct taxable person (the trustee in that capacity, not a beneficiary personally), and check that mandatory particulars appear on the notice, because a wrongly addressed assessment can collapse entirely.
Regularisation deserves its own paragraph because it is usually better than litigation for old structures. Where trustees discover years of missing declarations but no assessment has yet been raised, filing complete event and annual declarations now, with a clear covering letter and consistent valuations, normally restores the treaty exemption for the future and limits exposure for the past to the limitation period — whereas waiting for the office to strike first converts the same facts into assessments plus fines that must then be challenged uphill. Where assessments already exist, the réclamation should combine the late disclosure with the legal argument, so that the officer deciding the file can grant relief on the papers without a court case. In both postures, consistency across filings is the golden rule: the settlors named in the 2181 forms, the owners shown at the land registry, the declarants on the wealth-tax return and the heirs in the succession file must tell the same story, because computers cross-check and contradictions trigger audits.
Two final practical notes. General background on French administrative steps is published on service-public.fr, the official French public service website, and filing and payment run through impots.gouv.fr, the official French tax portal, where the trust filings are lodged with the non-residents office; trustees who cannot read French should never file blindly through the portal but should have the papers prepared by a professional and keep bilingual records. And where the trustees disagree among themselves — for example where one family trustee wants to disclose and another fears the tax consequences at home — the disagreement must be resolved under the trust deed and, if needed, by the English court before the French deadline expires, because the French office will not pause limitation while a family argues in another jurisdiction.
Conclusion
A British trust holding French property after Brexit is neither illegal nor unworkable, but it is a transparent instrument or it is an expensive one — France no longer offers a middle way. The 3% annual tax applies in principle to every foreign structure standing over French bricks and mortar, and the treaty exemption that saves British trusts is conditional on real, yearly disclosure of settlors, trustees and beneficiaries. The trustee declarations under the French tax code are not paperwork for the file; they are the title deeds of the exemption, and the fines for missing them fall personally on trustees who often never knew they were liable. On death, the trust interest enters the French succession through the trust-specific provisions of the tax code, the reserved share of children under the civil code constrains what the English deed can achieve for the French house, and residence tested person by person decides who declares what. Each of these layers has its own deadline — the event declaration on disguised changes, the annual declaration each year, the challenge by 31 December of the second year, the assessment within three years — and the family that diaries all four rarely pays more than the law requires.
The method that protects British families can therefore be written on a single page. Identify exactly what owns the French house at the land registry and disclose every link in the chain; file the event declaration on any change and the annual declaration every year, using the same filing as the foundation of the treaty exemption; value the property honestly at 1 January with a French appraisal kept on file; map each person’s tax residence annually and align the trustee filings with the individuals’ returns; prepare the succession in life with an express election of English law where appropriate and sworn translations ready for the notaire; and challenge any wrong bill first on exemption, then on valuation, then on limitation, always within the time limit and always with numbered exhibits. Run that discipline once and the English trust and the French house stop fighting each other: the trust does what it was created to do for the family, and France receives the transparency it demands in exchange for lifting the 3% charge.
