France's 3% real-estate tax: how the dispute moved from valuation to transparency, and what the 2027 reform changes.
A non-resident company has owned a prestige property on the coast for twenty years. Every spring it dutifully files its return; every spring it believes itself safe. Then, one morning, it receives a reassessment claiming the 3% tax over six years, surcharges included, on the ground that the beneficial owner it declared does not match the shareholder recorded in the foreign register. The procedural protection it thought it held, the right to be questioned before any reassessment, is denied. This scene, routine in specialist practices, captures a shift: France's annual 3% tax is no longer an impost feared for its base, but for its filing regime.
Set out in articles 990 D to 990 H of the French Tax Code (Code général des impôts), the annual 3% tax applies to the market value of French real estate held, directly or through interposed entities, by French or foreign legal entities (CGI, art. 990 D). Conceived in 1983 as an anti-opacity instrument, it matters in practice only through its exemptions, chief among them the one that rewards transparency over the ownership chain (CGI, art. 990 E, 3°). Yet it is precisely on the terrain of that transparency, rather than on property valuation, that the bulk of today's litigation concentrates.
Our analysis follows four lines of force. We first examine the transparency condition and the now-sanctioned boundary between shareholder and beneficial owner (I). We then turn to the procedural trap formed by the thirty-day tolerance and by filing errors (II). We address the structural blind spots of trusts and foundations that have no identified beneficiary (III). We finally show how the reform expected for 2027, arising from the anti-fraud statute, moves transparency from a matter of choice to a matter of obligation (IV).
I. Shareholder, beneficial owner and the mutual exclusivity of the two exemption routes
A. Two exemption methods that cannot be combined
The architecture of the central exemption from the 3% tax rests on an alternative that many practitioners long believed flexible, and that the Cour de cassation has just frozen. Article 990 E, 3° d) of the French Tax Code offers an entity that does not qualify for an automatic exemption two methods to escape the tax: either communicate each year, through the n° 2746 return, the location, nature and value of the real estate together with the identity of the shareholders, partners or other members holding more than 1% of the rights, or take on and honour an undertaking to communicate those same particulars upon the tax authority's request. The second route carries a valuable procedural guarantee: before any reassessment, the authority must question the entity within the framework of article R. 23 B-1 of the Tax Procedure Code (Livre des procédures fiscales), with a sixty-day period followed by a formal notice and a further thirty-day period.
The temptation, for the cautious taxpayer, was to combine the two regimes: take the initial undertaking, and the guarantee attached to it, while also filing annual returns for safety. The Commercial Chamber of the Cour de cassation closed that door in a landmark ruling, the Sweet Revenge decision (Cass. com., 1 April 2026, no. 25-10.605, reported). A British company owning a property in southern France had taken, in 2004, an undertaking to communicate on request, then spontaneously filed n° 2746 returns from 2006 onward. The Court holds that, while such entities "have a choice, in order to exempt themselves from the tax, between two methods of communicating information to the tax authority, those methods are mutually exclusive." In plain terms, one chooses a route; one does not stack them.
The procedural consequence is severe, and it is what drives the litigation. Once the entity began filing annual returns, it switched into the filing regime and thereby relinquished the guarantee of article R. 23 B-1 of the Tax Procedure Code. The Court approves the court of appeal for holding that this initiative "allowed the authority to issue a reassessment notice regularly, without following the procedure laid down by article R. 23 B-1." Commentators read the ruling as enshrining a definitive waiver: the switch from undertaking to annual return bars the entity from later claiming, for disputed years, the benefit of the specific adversarial procedure. We consider that this solution, legally consistent with the wording of the text, creates a considerable practical risk for wealth structures which, believing they were acting prudently, multiplied their filings without realising they were changing regime.
An older but convergent line of authority. This exclusivity is no radical novelty; it extends a line already drawn. The Cour de cassation had held, regarding a Belgian company, that an entity placed under the filing regime but in breach of its obligations could not then fall back on the undertaking regime for the same years (Cass. com., 18 May 2010, no. 09-65.941). The Court had also upheld the compatibility of the regime with tax treaties and EU law, noting that legal entities can "in all circumstances" obtain the exemption by evidencing either the filing of the returns or the communication of the information, without discrimination (Cass. com., 6 November 2019, no. 17-22.425). The Sweet Revenge ruling therefore breaks no new ground; it locks in, at the procedural stage, an exclusive-option logic from which advisers must now draw every consequence when structuring their clients' filings.
B. The shareholder / beneficial owner divergence and the shift to the long limitation period
The second, more insidious front concerns the statute of limitations. Because the 3% tax is treated as akin to registration duties, the authority's reassessment right is in principle governed by the shortened three-year period of article L. 180 of the Tax Procedure Code, but on a strict condition: that the chargeability of the tax has been "sufficiently revealed" by the registered document, without the authority having to conduct further investigations. Failing that, it is the ordinary six-year period of article L. 186 that applies, opening up to the authority the possibility of reassessing a far greater number of years.
The leading ruling here is Garoupe Investissement (Cass. com., 30 August 2023, no. 21-15.743). A Luxembourg company had, for years, filed its n° 2746 returns naming as holder of almost all the shares a natural person distinct from the corporate shareholder appearing in the official Luxembourg records. The Court lays down a rule of great practical scope: the shortened limitation period "is enforceable against the authority only if the chargeability of the duties and taxes has been sufficiently revealed by the registered document," and "that is not the case where the name of the beneficial owner mentioned in the annual returns is distinct from that of the principal shareholder appearing in the articles of association or the official documents drawn up by the State in which the legal entity owning the disputed property is established." The mere divergence of identity, on its own, requires external checks and defeats the benefit of the short period.
The reach of this solution is formidable because it severs two notions that filers readily conflate. The shareholder is the person appearing in the register, the gazette, the articles; the beneficial owner is the natural person who, at the end of the chain, truly benefits from the structure. The n° 2746 return targets "shareholders, partners or other members," and the consistency between the declared identity and the underlying legal documents conditions the sufficient revelation of chargeability. When a filer enters a beneficial owner with no apparent connection to the statutory shareholder, he believes he is being transparent; in reality, he hands the authority a ground for applying the six-year period. Professional commentary indeed stresses that, in practice, any concrete application of the shortened period to the 3% tax has become almost impossible to find.
A coherent body of authority confirmed by the lower courts. Far from being isolated, Garoupe consolidates an already-structured line of appellate case law. The Aix-en-Provence Court of Appeal, whose 16 February 2021 judgment (no. 18/12004) gave rise to the appeal decided in 2023, had set out the principle in the same terms, noting that the Luxembourg gazette named an offshore company while the return designated a natural-person beneficiary of another State. That same court had, as early as 2017, set aside the shortened period where the returns named as partner a person whose status did not appear in the corporate documents (CA Aix-en-Provence, 21 March 2017, no. 16/10423), and the Nîmes Court of Appeal had found a mere beneficial-ownership declaration prepared for anti-money-laundering purposes to be insufficient, for want of corroboration (CA Nîmes, 12 November 2020, no. 18/04663). Earlier, a series of rulings, Bambi, Ylona, Beauvalais, Autophon Funk, had already refused to elevate the acquisition deed or mere correspondence to the rank of an act "revealing" chargeability. The lesson we draw is clear: a n° 2746 return opens the short limitation period only if it is, on its own and without cross-checking, intrinsically consistent with the official registers.
II. The procedural trap: the thirty-day tolerance and filing errors
A. The thirty-day tolerance, a narrower safety net than it appears
Practitioners are familiar with the "thirty-day tolerance," often presented to clients as a reassuring second chance. Its basis is not statutory but administrative: it traces back to a ministerial answer (réponse Loncle) of 13 March 2000, taken up and refined by the tax authority's published doctrine (BOFiP, BOI-PAT-TPC-30, § 20). The authority accepts that an entity which could have claimed the exemption of article 990 E, 3° d) or e), but which has neither filed the n° 2746 return nor taken the required undertaking, is not liable to the tax if it regularises its position within thirty days of a formal notice, or even spontaneously, before any notice. The mechanism dovetails with the ex-officio assessment of article L. 66 of the Tax Procedure Code, which, for this duty-akin tax, presupposes a prior formal notice that has gone unheeded for thirty days.
The trap lies in the limits, rarely spelled out to the client, of that tolerance. It applies, first, only to the first regularisation request, and for all non-time-barred years; it does not renew. It covers, second, only one category of default: the outright absence of a return or undertaking. The Cour de cassation held long ago that this tolerance is solely intended to regularise taxpayers who have not filed, and not those who have filed incompletely or incorrectly (Cass. com., 31 January 2006, no. 02-20.387). In other words, the clumsy filer who lodged a n° 2746 return marred by inaccuracies cannot shelter behind the tolerance: he is treated more harshly than the one who filed nothing at all.
When the thirty-day period expires without regularisation, the consequences are not confined to late-filing penalties on forms: it is the tax itself that becomes chargeable. The Aix-en-Provence Court of Appeal said so bluntly, holding that after the period expires the taxpayer owes not only late interest and penalties but the 3% tax itself (CA Aix-en-Provence, 7 March 2023, no. 19/12727). The penalty machinery then deploys under the ordinary rules: late interest under article 1727 of the French Tax Code, and the graduated surcharges of article 1728, 10% for mere delay, 40% where no return is filed within thirty days of a first formal notice, 80% after a second unsuccessful notice. We stress to our clients a point the tolerance too often obscures: once the period has passed, late regularisation no longer neutralises the tax; it merely mitigates the ancillary charges.
B. The fate of exemptions in case of filing error: a high-risk grey zone
What becomes of the exemption where the return is correct in principle but tainted by an error on a property's surface area or its valuation? The question lies at the heart of practitioners' concerns, and the answer is less settled than one would wish. The reference framework remains the ministerial answer Masson of 7 March 2023, which clarified the "right to error" regime applicable to the 3% tax. That answer sets three limits: the right to error is conditional on the taxpayer's good faith; it concerns only taxpayers who have not filed or taken the undertaking; and it does not apply to taxpayers who have filed incomplete or incorrect returns, whose only relief lies in the reduction of late interest, by half in case of spontaneous regularisation, by 30% if regularisation occurs during a review (CGI, art. 1727; LPF, art. L. 62).
Candour, here, is what prudence demands: to our knowledge, there is to date no dedicated decision settling, for the 3% tax, the fate of the exemption where the error bears specifically on the surface area or the market value of a property. The recent decisions on this tax concern the identity of capital holders, not the physical characteristics or value of the assets; and the lessons drawn from other taxes, local property tax, for instance, where the authority enjoys a general power to correct rental-value errors, transpose only with great caution. This absence of dedicated case law is no comfort; it is, on the contrary, an uncertainty that resolves, in the event of a review, against the taxpayer, who bears the burden of proving that the assessment is excessive.
The "recovery for the future" logic. One cross-cutting principle nonetheless sheds light on the analysis. Where an entity loses the exemption, whether for breach of the undertaking or for a defective return, the authority's doctrine and article 990 F of the French Tax Code organise a catch-up mechanism strictly oriented toward the future: the entity may recover the benefit of the exemption from the year in which it communicates the full particulars and, where applicable, takes a fresh undertaking, but the tax due for prior, non-time-barred years remains chargeable (BOFiP, BOI-PAT-TPC-20-20, § 560). No provision conditions this catch-up on the nature of the error, and none distinguishes between an omitted partner, a surface-area error or an under-valuation. Our reading is therefore the following: in the absence of a specific protective regime, any inaccuracy affecting a n° 2746 return must be treated, in the risk analysis, as liable to defeat the exemption for the past, with regularisation taking effect only for the future. Hence the importance of a rigorous upstream filing review, rather than a reassessment endured downstream.
III. Structural blind spots: trusts and foundations without an identified beneficiary
A. The taxability of trusts and the rebuttable presumption of seat
The treatment of trusts and foundations under the 3% tax is one of the most delicate areas, because it pits the logic of the tax, which reasons in terms of shareholders and members, against structures that, by their very construction, do not always have any. The starting point is no longer debated: a trust, defined by article 792-0 bis of the French Tax Code as a set of legal relationships under foreign law, must be regarded as an "institution comparable to the fiducie" within the meaning of article 990 D, so that French real estate placed in a trust is subject to the 3% tax, including where the trust has no legal personality. The Conseil d'État said so unambiguously when it upheld the administrative doctrine that brings all trusts within the scope of the tax (CE, 9 May 2019, nos. 426431 and 426434, Amicorp Ltd).
That same decision brings a nuance favourable to the taxpayer, which it would be imprudent to overlook. For the application of the exemptions conditioned on the location of the seat, France, the European Union, or a State bound to France by an administrative-assistance convention, the authority presumes that the trust has its seat in the State or territory under whose law the legal relationships establishing it were created. The Conseil d'État specifies that this presumption is not irrebuttable: the entity retains the ability to prove the contrary and thus to rebut the presumed connection. The construction is consistent with the functional characterisation adopted elsewhere: although a trust is, in civil law, devoid of legal personality and constitutes merely a set of legal relationships (CE, 20 March 2020, no. 410930), it nonetheless falls within the broad category of "legal entities" targeted by article 990 D. The notion of legal entity, for the purposes of the tax, thus extends beyond that of a body corporate.
B. The dead end of entities with no real beneficiary on 1 January
The real difficulty arises where the structure, by its very nature, makes it impossible to identify any real beneficial owner at the date of the chargeable event. This is the decisive contribution of the Beaux-Arts Stiftung ruling (Cass. com., 10 May 2024, no. 21-11.230, reported). A Liechtenstein foundation had filed returns in order to claim the exemption but could designate only a future, hypothetical beneficiary of its assets. The Cour de cassation lays down a strikingly clear principle: "Only the real beneficial owners on 1 January of the tax year of the legal entities concerned, and not prospective beneficiaries, may be treated as shareholders, partners or other members holding more than 1% of the shares, interests or other rights."
The consequence is implacable for an entire category of structures. A foundation that has neither shareholders, nor partners, nor other members, and that is unable to designate a current beneficiary on each 1 January, does not meet the conditions of article 990 E, 3°, and therefore remains liable to the 3% tax on its French real estate. The Court adds a decisive element: this situation flows from "a free choice" of organisation, which is not enforceable against the tax authority. In other words, organisational opacity, even legitimate under the foreign law governing the structure, cannot be invoked to escape a condition that the legislature precisely intended in order to combat opacity. The solution, developed for foundations, transposes by analogy to purely discretionary trusts in which no beneficiary is determinable on 1 January.
An openly anti-fraud logic, validated by the highest courts. This severity is no jurisprudential accident; it forms part of a coherent whole that the supreme courts have consolidated. The Cour de cassation declined to refer a priority constitutional question, holding that the terms "shareholders, partners or other members" are sufficiently precise and must be understood broadly to capture all entities, whatever their form, in service of the fight against tax fraud and evasion (Cass. com., QPC, 11 April 2018, no. 17-21.938, Nafond Privatstiftung). The Conseil constitutionnel had itself upheld the regime, noting that reserving the exemption to entities established in a State offering administrative assistance to France bears a direct relationship to the object of the law (Cons. const., 16 September 2011, no. 2011-165 QPC, Heatherbrae Ltd). For trusts, the n° 2746 return requires in practice identifying the real holders of rights, depending on the deed, the settlor where the trust is revocable, the beneficiaries where it is irrevocable, and attaching, where appropriate, the trust deed; absent a current beneficiary, the exemption is out of reach. We see in this a structural warning addressed to discretionary arrangements: what makes their wealth-planning appeal also mechanically triggers their liability to the 3% tax.
IV. The 2027 reform: from optional transparency to mandatory transparency
A. Abolition of the undertaking option and generalisation of the annual return
All the litigation set out above rests on one datum that the legislature is about to alter profoundly: the existence of a choice between two exemption routes. The statute on the fight against social and tax fraud, its bill presented in the Council of Ministers in autumn 2025 and its parliamentary passage completed in spring 2026, contains a provision, arising from an amendment adopted in the Senate, that rewrites the transparency regime of the 3% tax. Subject to verification of the wording finally promulgated and of its exact entry-into-force date, announced for 2027, the reform purely and simply abolishes the option to undertake to communicate set out in 990 E, 3° d), in favour of a systematic annual return to be filed by 15 May at the latest. Transparency ceases to be an undertaking one subscribes to; it becomes a return one files, every year, with no alternative.
The objective stated in the preparatory works is explicit: to facilitate the monitoring of exempt entities by generalising the filing of the n° 2746 return, to improve knowledge of ownership and transmission chains, and to accelerate reviews that the undertaking option slowed down, since non-resident entities questioned do not always respond, or respond only partially, to the authority's requests. We observe that this evolution, presented as technical, carries a major and largely underestimated legal consequence: by abolishing the undertaking option, the legislature deprives of all purpose the procedural guarantee of article R. 23 B-1 of the Tax Procedure Code, which was attached to it. The Sweet Revenge litigation, which sanctioned precisely the switch from undertaking to return, thus loses, for the future, most of its raison d'être: there will soon no longer be a second route to abandon, nor a guarantee to claim.
B. The mandatory appointment of a representative in France
The reform's second limb is just as structural for non-resident owners. The text adopted provides that an entity subject to the filing obligation which has no permanent establishment in France must designate, in its return, a natural or legal person resident for tax purposes in France and authorised to receive on its behalf all communications, procedural documents and notifications from the authority relating to the control of the tax. The mechanism includes a substitution rule whose severity must be measured: failing such a designation, the entity in the ownership chain closest to the real estate and known to the authority, whether itself exempt or not, will be deemed authorised to receive those documents on the taxpayer's behalf.
This machinery of a statutory tax representative, already familiar from other taxes, changes the procedural picture. It neutralises in advance much of the litigation that foreign companies had until now drawn from the irregularity or the absence of effective receipt of formal notices, where they were unidentified, had changed address or answered no correspondence. By guaranteeing the authority an interlocutor resident for tax purposes in France, the legislature secures the procedural chain of the review and deprives the recalcitrant taxpayer of the defective-notice argument. For complex holding structures, the stake is concrete: an intermediate entity, even exempt, may find itself deemed the addressee of procedural documents targeting a sister entity or a group company, with the practical responsibilities that entails.
C. Practical recommendations: anticipate rather than endure
Audit filing consistency before the review. The cross-cutting lesson of Garoupe and Sweet Revenge is that a 3% tax review is won or lost upstream, in the quality and consistency of past returns. We recommend that every non-resident entity holding French real estate carry out, without waiting for a formal notice, a retrospective review of the n° 2746 returns for the non-time-barred years, checking point by point the concordance between the declared beneficial owner and the shareholder or partner appearing in the underlying legal documents. Any undocumented divergence exposes the entity to the six-year period and must be explained or corrected before the authority seizes upon it.
Clarify the chosen filing regime and anticipate the 2027 switch. Entities still under the undertaking regime must understand that this regime is set to disappear and that any annual return filed in the meantime already shifts them, today, into the filing regime with loss of the procedural guarantee. Rather than enduring this transition, it is better to organise it: preparing, as early as the current year, a complete and accurate n° 2746 return, and identifying the future tax representative in France, are low-cost diligence steps measured against the risk. For trusts and foundations, the audit must focus on the structure's very ability to designate a real beneficial owner on 1 January; where that designation is structurally impossible, the 3% tax should be built in as an accepted cost of ownership, not treated as a risk one hopes to avoid through silence.
Conclusion
The 3% tax has changed in litigious nature. Property valuation, which historically formed its central stake, has given way to a dispute about transparency and procedure, where the consistency between the declared identity and the reality of the ownership chain decides both the exemption and the length of the reassessment right. The Garoupe, Beaux-Arts Stiftung and Sweet Revenge rulings trace a convergent and demanding body of case law, which sanctions opacity and filing inconsistency far more surely than it sanctions under-valuation.
The reform expected for 2027 completes this movement. By abolishing the undertaking option and imposing an annual return coupled with a tax representative in France, the legislature moves transparency from the register of choice to that of obligation, and simultaneously deprives taxpayers of the procedural margins that recent litigation exploited. The paradox is striking: the Sweet Revenge ruling, barely handed down, already sees its practical reach reduced by the reform that succeeds it.
Our recommendation is clear: the 3% tax must no longer be approached as a springtime formality, but as a control mechanism whose security depends entirely on filing rigour and anticipation. Auditing the consistency of past returns, clarifying the applicable regime without delay, identifying the future tax representative and, for discretionary structures, accepting the tax where the exemption is out of reach, these are, as of today, the diligence steps that will separate the untroubled taxpayer from the reassessed one.
Frequently asked questions
My foreign company files the n° 2746 return every year, am I safe from a 3% tax reassessment?
Not necessarily. Regular filing protects you only if the declared particulars are accurate and consistent with your official legal documents. If the beneficial owner you mention differs from the shareholder appearing in your articles or registers, the authority can set aside the three-year limitation period and reassess over six years (Cass. com., 30 August 2023, no. 21-15.743). An incomplete or incorrect return also exposes you to the chargeability of the tax and to surcharges, without the benefit of the administrative tolerance.
I took an undertaking to communicate in 2004 and then filed annual returns, did I keep my procedural protections?
No. Since the Sweet Revenge ruling (Cass. com., 1 April 2026, no. 25-10.605), the two exemption methods are mutually exclusive. By spontaneously filing annual returns after taking an undertaking, you switched into the filing regime and waived the procedural guarantee of article R. 23 B-1 of the Tax Procedure Code. The authority may then issue a reassessment without questioning you beforehand.
Can the thirty-day tolerance save me if I never filed?
Yes, but only once and on a strict condition. The tolerance arising from the Loncle answer (BOFiP, BOI-PAT-TPC-30, § 20) applies only to the first default consisting of a complete absence of return or undertaking, and only if you regularise within thirty days of the formal notice. It does not cover incomplete or incorrect returns (Cass. com., 31 January 2006, no. 02-20.387). Once the period has passed, the tax itself becomes due, with interest and surcharges.
Can my trust or foundation escape the 3% tax if it has no designated beneficiary?
It is precisely the opposite. A trust or foundation holding French real estate is liable to the tax (CE, 9 May 2019, no. 426431). To be exempt on transparency grounds, it must be able to designate real beneficial owners on 1 January of each year. A structure that can designate only prospective or hypothetical beneficiaries does not meet that condition and remains liable (Cass. com., 10 May 2024, no. 21-11.230). The absence of an identifiable beneficiary, far from exempting, condemns to the tax.
What will actually change with the 2027 reform?
Subject to the wording finally promulgated, two major changes are expected. First, the option to undertake to communicate disappears: the transparency exemption will require an annual n° 2746 return, to be filed by 15 May at the latest. Second, any entity without a permanent establishment in France must designate a representative resident for tax purposes in France to receive procedural documents, failing which the entity closest to the real estate in the chain will be deemed authorised. Transparency becomes a systematic obligation, with no alternative.
