Trusts French tax reporting is not an optional Anglo-Saxon courtesy. France does not offer a domestic trust as a standard estate vehicle. What it does offer, since the 2011 rectifying finance law, is a reporting and tax perimeter for foreign trusts that touch a French settlor, a French beneficiary, a French administrator, or French-situs assets. Article 1649 AB CGI puts the filing on the trustee or administrator. Families who treat a Delaware, Jersey, or Singapore trust as invisible in Paris are describing a reporting bomb, not a plan. The bomb is the undeclared trust, not the existence of trusts in other legal systems.
This note is general information for education. It is not a trust deed review, a mandate, or personalised tax advice. Qualification, value, and any levy depend on the deed, the people, the assets, and counsel who can read 1649 AB together with the BOFiP comments and the IFI / succession articles that sit beside it.
Vellum Finance is a fee-only multi-family office. The useful questions are who must file, what “equivalent value” meant under ISF and still means conceptually for IFI, and when the foreign trustee’s silence becomes the French family’s penalty. Discretion in this house means a complete file. It does not mean an empty annex.
Trusts French tax reporting: why the file exists
French civil law uses succession, gifts, companies, assurance-vie, and, in a narrow statutory form, fiducie. A common-law trust is a different animal: a trustee holds title for beneficiaries under a deed the French notaire does not draft. After 2011, France stopped treating that animal as fiscally unnameable. The administration’s legal comments are grouped in BOFiP BOI-DJC-TRUST on dispositions relating to trusts. Forms and notices sit on impots.gouv.fr, including the 2181-TRUST series. The CGI articles to read with those pages are 1649 AB on Légifrance (reporting), 990 J (the sui generis levy when the wealth-tax path is not taken), and the IFI provisions that succeeded the old ISF trust article.
The policy is look-through plus reporting. France wants names (settlor, beneficiaries, administrator), terms (revocable or not, discretionary or not), and values (assets and accumulated income). It wants them when a French tax resident is in the picture, when French assets are in the picture, or when the administrator is French. A family that “moved the trust to Singapore” without removing the French settlor or the French flat has not left the perimeter. It has changed stationery.
Article 1649 AB: event declaration and annual declaration
Article 1649 AB creates two duties. The first is event-driven: constitution, modification, or extinction of the trust, plus the content of its terms. Modifications include changes of trustee, of beneficiaries, of the deed, and of the asset list in the ways the comments describe. The second is annual: the market value, on 1 January, of the assets and rights placed in the trust and of their accumulated proceeds. The 2181-TRUST1 family covers the event. The 2181-TRUST2 family covers the annual snapshot. Filing calendars and addresses are on the administration’s notices, not on a private-bank slide.
Who must file is the administrator (administrateur du trust), a term the comments read as the trustee and as any person in an equivalent role. The duty attaches, in the wording the forms still use, when the administrator is tax-resident in France, or when a settlor or a beneficiary is tax-resident in France, or when the trust includes a right or asset situated in France. Extra limbs exist for non-EU trustees who acquire French real estate or who enter into a business relationship in France. The French family cannot assume that “the trustee in Jersey files if they feel like it.” If the trustee fails, the French settlor or beneficiary still lives with the French penalty and with the French wealth-tax analysis. Joint practical responsibility is the working hypothesis even when the legal addressee of the form is the trustee.
Failure or insufficiency of the 1649 AB declarations is sanctioned. BOFiP’s comments on penalties still point to article 1736, IV bis CGI: a fine of €20,000 (or a percentage of the assets in the versions and cases the article provides, when that computation is higher). This article does not invent a 2026 tariff. It notes that non-filing is priced, and that the price is not “a reminder letter.” There is also a wealth-tax consequence, which is the next heading.
Trustee, administrator, settlor: who is on the hook
The trustee is the filing person. The settlor is often the person France treats as still owning the assets for wealth-tax and, in many fact patterns, for transmission. The beneficiary can be treated as settlor in the “deemed settlor” cases the comments describe, especially after the original settlor’s death if the trust continues. A protector, a “letter of wishes,” and a family member who can remove the trustee can look like control. Control is a reporting and a substance fact. It is also how a trust that was sold as discretionary and irrevocable becomes, in Paris, a revocable pocket of the settlor.
Administrators who are themselves French tax residents file even when the settlor and the beneficiaries are abroad, for the French-situs assets and on the terms the comments set. Dual roles (a child who is both beneficiary and de facto protector) should be written down. The form is not the place to discover them. The 2026 inheritance-tax country map will not save a trust that was never declared in France. It may explain a second duty in the trustee’s home state. Two duties. One deed.
Equivalent value: from ISF to IFI, conceptually
Under ISF, article 885 G ter CGI treated assets placed in a trust as belonging to the settlor for wealth-tax purposes, or to the beneficiaries in the cases the article named, at their equivalent value. ISF was repealed. IFI replaced it as a real-estate wealth tax. The conceptual move did not disappear. Assets that are real estate, or that represent real estate, and that sit in a trust, still have to be located in an IFI perimeter when the settlor or the relevant person is a French resident, or when the bricks are French. The old ISF comments remain useful as a map of who is deemed to own what. The live tax is IFI, with its own base, threshold, and debts. Vellum’s inventory of that base is the note on French wealth tax IFI 2026.
Real estate inside a trust, and the sui generis levy
If the trust’s French-real-estate equivalent value belongs in IFI, it belongs on the IFI return, with the same look-through honesty a company layer would require. If the reporting and wealth-tax path is not taken, article 990 J CGI still describes a sui generis levy on the assets placed in the trust, at a published rate aligned with the top of the wealth-tax logic, due by the trustee, with solidarity. The levy is the statute’s answer to an undeclared or unallocated trust, not a planning tool. Paying 990 J because nobody wanted to name the beneficiaries is not discretion. It is an expensive silence.
Financial assets in a trust are generally outside IFI, as they are outside IFI when held directly. They are not outside 1649 AB. They are not outside succession analysis. Families who say “the trust is only securities, so France does not care” are reading the IFI base and ignoring the reporting statute. France cares in two columns. IFI is one. 1649 AB is the other.
When a foreign trust is a reporting bomb
The bomb has a short fuse in three recurring files. One: a US or English will pours assets into a testamentary trust for children, one of whom is now a French tax resident. Nobody tells the French notaire. Nobody files 2181-TRUST. CRS on the trust’s bank account still leaves the trustee’s jurisdiction. Two: a lifetime irrevocable trust was created when the family lived in London; the settlor later becomes French-resident and keeps the old deed in a drawer. Three: a trust holds a Paris apartment through a foreign company, and the family believes the company has made the bricks disappear. Look-through for IFI, 1649 AB for the trust, and a company annex for the foreign entity can all apply. Three annexes. One apartment.
Distribution from a trust to a French resident is a fourth file: income characterisation (distribution of income versus capital), possible 155 A or CFC overlays if the trust is used as a personal-services or investment company, and gift or inheritance analysis when the distribution is in substance a transmission. This article does not invent a rate for that overlay. It notes that “the trustee sent a dividend” is not a French tax characterisation.
Penalties, 990 J, and late IFI are how the bomb is priced. CRS and, where relevant, FATCA are how it is found. A foreign trustee who refuses to file 1649 AB because “we do not do French forms” does not bind Bercy. The French settlor or beneficiary still needs a French solution: a new trustee who will file, a reconstruction of the deed, or, in some cases, an unwind that is itself a taxable event. Hoping the trust is too old to see is not a solution.
What a family office should inventory
List every trust, foreign foundation, and nominee arrangement that names a family member or a family company. For each, name the proper law, the trustee, the settlor, the beneficiaries, the protector, and whether the deed is revocable or discretionary. List French tax residents in that cast as at 1 January and as at any event date. List French-situs assets, including companies that hold French bricks. Collect the last 2181 filings, or document that none exist. Then read BOI-DJC-TRUST, the 2181 notices on impots.gouv.fr, and article 1649 AB on Légifrance. The Vellum Finance services model is fee-only coordination so that the trust deed, the IFI inventory, and the succession map are one chart, not three stories.
The same three misses still dominate: a trustee who never filed 1649 AB, a settlor who became French-resident without opening the deed, and a Paris apartment sitting behind a trust and a company as if both layers were opaque.
Conclusion
Trusts French tax reporting under article 1649 AB is an event file and an annual 1 January file, charged to the trustee, with French settlors, beneficiaries, administrators, and French assets in the net. Equivalent value moved from ISF into an IFI look-through for bricks, while 990 J waits for the undeclared trust. A foreign trust can be a valid foreign instrument. In France it is a reporting perimeter. Read impots.gouv.fr and BOFiP, put the deed next to the IFI and succession maps, and let facts and counsel decide whether the trust still has a purpose other than silence. Silence is the bomb.
Discretion. Stability. Prosperity.
