Executives and high‑net‑worth individuals with assets in France face a more demanding cross‑border compliance and enforcement environment than ever before. France tax structuring and defensive planning must therefore be calibrated not only to domestic rules but to a fast‑moving international architecture of information exchange and minimum taxation.

This article provides practical, actionable guidance for executives under international tax scrutiny or seeking to reduce future exposure. It addresses recent developments that matter to defence and structuring choices, from the OECD’s Pillar Two and new EU DAC reporting pillars to France’s domestic reporting and penalty rules, and sets out concrete steps to prepare, respond and litigate where necessary.

Understand the evolving international reporting landscape

The global tax architecture has changed materially since 2023: the OECD/G20 Pillar Two (global minimum tax) and a series of EU directives extending automatic information exchange have created new reporting obligations and widened the bases for cross‑border enquiries. These measures affect when and how French authorities (and foreign counterparts) obtain data about multinationals and wealthy individuals, and how jurisdictional top‑up taxes and information exchanges are coordinated.

France transposed the EU minimum tax rules into domestic law through its 2024 finance measures and has implemented the basic filing framework for the GloBE/Pillar Two rules, so executives who are part of multinational groups must assume additional reporting and possible top‑up tax consequences for group structures and intercompany allocations.

The EU also extended administrative cooperation (notably the DAC series) to include platform reporting and, more recently, top‑up tax information exchanges (DAC7/DAC8/DAC9). Member states are required to put national measures in place to permit exchange of Pillar Two top‑up information and platform‑derived data; this expands the risk that cross‑border asset and income data will be matched and screened by tax authorities. Executives must factor these flows into both proactive disclosures and reactive defence.

Take immediate, evidence‑based defence steps when contacted

When the tax authority opens an inquiry, time and evidence discipline matter. Preserve contemporaneous documents (contracts, board minutes, remuneration records, bank and custody statements, trustee reports), record the chain of custody, and avoid speculative written statements without counsel. Early organisation of documentary evidence materially improves negotiation outcomes and reduces the risk of penalty aggravation.

Engage specialised French tax counsel (and international advisors where multinational issues arise) before producing large sets of documents or negotiating. Counsel should lead privilege and production strategy, assess whether administrative appeal or early settlement (transaction) is preferable, and coordinate parallel litigation or criminal‑law risk management when necessary.

Consider voluntary regularisation where appropriate, but only after a clear risk/benefit analysis. French voluntary disclosure routes can mitigate criminal risk and penalty exposure in many cases; however, the administrative practice and the scope of available relief depend on the facts, the type of omission and whether foreign‑sourced information has already been exchanged. Early legal advice preserves options and avoids procedural pitfalls.

Reassess holding‑company and ownership chains for defensibility

Structuring for tax efficiency must be reconciled with defensibility under substance‑based tests. French rules and recent international standards prioritise economic substance: holding companies and intermediaries should have genuine personnel, decision‑making, and commercial activity where they claim tax residency and reliefs. Purely paper structures are increasingly vulnerable to reclassification and denial of treaty or preferential treatment.

Where real estate in France is involved, transparent holding vehicles (such as French sociétés civiles immobilières, SCI, used with proper governance) and clear accounting for rental operations help reduce exposure to IFI and local taxes. For cross‑border holdings, ensure that intercompany agreements (management services, loans, licensing) are documented, priced and performed in line with commercial reality to withstand transfer‑pricing scrutiny.

Document board minutes, meeting attendance, and decision‑making processes; contemporaneous evidence of substance (office leases, payroll, local contracts) is often decisive when authorities test the economic reality of a structure.

Manage executive compensation, transfers and transfer pricing exposures

Executive remuneration, equity awards and cross‑border secondments frequently trigger disputes over tax residence, employment income sourcing, social contributions and corporate deductibility. Keep precise records of where duties are performed, time spent in France and abroad, and the legal basis for imposition in each jurisdiction; mobility logs and contemporaneous assignments are critical evidence.

For executives holding equity or options in multinationals, clear grant documentation (exercise timing, tax equalisation policies, withholding arrangements) reduces uncertainty. Tax gross‑ups and employer withholding practices should be reviewed to ensure they align with the jurisdictions involved and with applicable treaties.

Transfer pricing documentation should address management fees, intra‑group services and financing on a robust, contemporaneous basis. French auditors and DGFiP increasingly rely on global country‑by‑country data and Pillar Two calculations to spot mismatches; therefore, transfer pricing reports must be integrated with group‑level reporting and public‑filed disclosures.

Protect private wealth: IFI, life insurance and trust reporting

Real‑estate wealth in France remains a major focus: the Impôt sur la Fortune Immobilière (IFI) applies to non‑residents whose French‑situs real‑estate net value exceeds the threshold (currently €1.3 million), and France requires accurate annual declarations and valuation bases for taxable property. Non‑residents must therefore monitor thresholds and filing deadlines closely to avoid late‑filing penalties and extended limitation periods.

Life‑insurance envelopes (including Luxembourg private placement contracts) are common wealth‑management tools for executives; they bring specific French tax and succession benefits but also specific disclosure and anti‑abuse risks. Ensure contract documentation, premium provenance and beneficiary designations are consistent with the intended tax treatment and with the executive’s residency profile.

Trusts are subject to specific French declaratory regimes when they have a link with France: trustees and administrators may face annual and event‑driven declaration obligations, and omissions can attract sanctions. Executives using trust vehicles should confirm compliance with French trust‑reporting rules, disclose when required, and maintain trustee records so that valuation and beneficiary information are available on demand.

Anticipate enforcement, penalties and litigation strategies in France

French procedural rules and sanction regimes are consequential. Administrative penalties for late or insufficient declarations can range from percentage‑based surcharges to sharp increases (for deliberate omission or fraudulent schemes), and additional criminal exposure may follow in serious cases. The BOFiP and the Code général des impôts set out majoration scales that advisers must consider when modelling settlement and litigation choices.

France operates a well‑developed administrative litigation system and the so‑called commission des infractions fiscales (CIF) plays an important role where criminal or quasi‑criminal issues arise. In contentious cases, consider early use of administrative appeal procedures, requests for suspension of execution, protective interim relief and, where appropriate, negotiation under the “transaction” mechanisms that the tax administration sometimes offers for complex dossiers.

Preserve litigation options by complying carefully with deadlines, paying attention to limitation periods (which can be extended in cases of omission or fraud) and documenting remediation steps. Well‑timed expert reports (valuations, transfer‑pricing studies, tax opinions) materially improve outcomes at both administrative and judicial levels.

Practical defence and structuring for executives with French assets is a hybrid of legal compliance, commercial substance and disciplined documentation. The shifting international environment, Pillar Two top‑up taxes, expanded DAC reporting and routine cross‑border data exchanges, means that yesterday’s structures may be exposed today.

Actively reassess holding chains, mobility policies and wealth vehicles against the latest reporting and enforcement practices; retain specialist counsel early; and prioritise evidence‑rich remediation where there is exposure. These steps materially reduce enforcement risk and preserve more favourable settlement and litigation outcomes.

Next steps checklist for executives and their advisers

1) Rapidly inventory French‑situs assets, cross‑border contracts and trustees; confirm IFI thresholds and filing status. 2) Assemble contemporaneous documentation for board decisions, remuneration, and intercompany agreements. 3) Engage experienced French tax counsel to lead any contact with authorities and coordinate voluntary regularisation where appropriate.

Prepare a defensible narrative: timelines, economic rationale for structures, and evidence of substance. Where Pillar Two, DAC7/DAC9 or other automatic exchanges touch your arrangements, run a coordinated review with international tax and transfer‑pricing specialists to quantify potential exposures.

Finally, ensure governance and record‑keeping changes are made now so that future mobility, equity awards, life‑insurance strategies and holding‑company decisions are both tax‑efficient and audit‑resilient.

These practical measures reduce immediate risk and build a durable defence posture if scrutiny intensifies. They also position executives to take advantage of legitimate planning opportunities that remain robust under current international rules.

If you need assistance, seek a firm with demonstrated experience in French tax audit defence, cross‑border litigation and wealth structuring; early, specialist advice is almost always the most cost‑effective route to protect assets and reputations.
