France’s tax landscape has evolved significantly since 2023 with a series of international and domestic measures that materially affect cross‑border owners of companies and real estate. Multinationals, holding companies and high‑net‑worth individuals who own French property or structures that hold French real estate must reassess exposures created by new minimum tax, transparency and asset‑tax rules.

This article sets out practical, prioritized steps to secure cross‑jurisdictional holdings and property in France in light of recent reforms, with attention to corporate structures, real‑estate vehicles, documentation and dispute prevention. The guidance is aimed at corporate groups, executives and non‑resident owners seeking actionable compliance and risk‑mitigation measures in 2026 and beyond.

Assess the impact of major recent tax reforms

Begin with a concise mapping of which new rules apply to your situation. The global minimum tax (OECD Pillar Two / GloBE) has been transposed into French law and applies to large multinational groups for fiscal years opened on or after 31 December 2023; the French administration has published implementation guidance and filing timetables.

On transparency, the EU DAC8 framework (reporting of crypto‑asset providers and related data) entered into force for 1 January 2026 at EU level, and France adopted transposition measures late in 2025; obligations on platforms and some custodians may therefore generate reporting requirements affecting ownership chains that use crypto or tokenised real estate.

Domestically, the French real‑estate wealth tax (IFI) and local property taxes continue to apply to owners of French property (including non‑residents owning directly or indirectly), with the IFI taxable threshold and reporting rules actively updated in recent fiscal years, precise thresholds and dates should be checked when valuing portfolios at 1 January of the tax year.

Revisit ownership vehicles and corporate form

Review whether the current vehicle holding your French property (direct ownership, SCI, French subsidiary, foreign company, trust or fund vehicle) remains optimal. Different vehicles face different tax treatments for IFI, local taxes and corporate taxes, for example, SCI holdings and shares in real‑estate companies are included in IFI calculations in defined proportions.

For multinational groups, Pillar Two may alter the economics of cross‑border holding companies: the GloBE rules can trigger an effective minimum tax in jurisdictions where the consolidated effective tax rate falls below 15%, which can affect funding, debt/equity mix and the attractiveness of certain low‑tax holding locations. Early modelling of effective tax rate outcomes at the group and entity level is essential.

Where restructurings are contemplated, factor in French anti‑avoidance, transfer‑pricing and substance tests. A formal reorganisation that lacks commercial substance or that frustrates treaty entitlements may attract challenges; consider incremental operational substance (management, employees, contracts) where legitimate group operations exist.

Optimize real‑estate holding structures for tax and compliance

For individuals and groups that hold French property indirectly via companies or funds, ensure that valuations and debt allocations used for IFI and local tax purposes are robust and well documented. French guidance and BOFiP commentary specify valuation approaches, debt treatment and the fraction of corporate value attributable to real estate.

Consider restructurings that are tax‑efficient but defensible: converting direct ownership into an operating real‑estate company with genuine commercial activity can, under strict conditions, affect IFI eligibility for exemptions or deductions. Conversely, artificial fragmentation of ownership to avoid thresholds is high risk. Rely on tailored modelling and legal opinions before taking action.

If crypto or tokenised assets are part of the ownership chain, evaluate the impact of DAC8 reporting on counterparties and platforms: token transfers that map to beneficial‑ownership changes may generate automated disclosures that expand the information available to tax authorities. Coordinate treasury, legal and compliance teams to close reporting gaps.

Strengthen documentation, transfer pricing and substance evidence

French transfer‑pricing documentation rules were tightened in recent reforms and the LPF now requires large groups to hold contemporaneous master and local files in line with OECD standards (Article L.13 AA). Failure to maintain consistent documentation can give rise to presumptions in tax audits. Ensure your master file, local file and country‑by‑country reporting are up to date and reconciled with statutory accounts.

For intra‑group financing and management services that allocate costs to French entities, prepare a clear business case and supporting contracts. Where the tax administration queries whether profits were shifted away from France, substantive evidence of pricing, commercial rationale and decision‑making location is the primary defence. Consider obtaining Advance Pricing Agreements (APAs) for high‑value or recurring cross‑border arrangements; the French APA route is available and can materially reduce audit risk.

Document board minutes, management meetings and the presence of decision‑makers in the jurisdiction that claims tax residence. For groups relying on foreign holding entities, contemporaneous evidence of independent directors, office leases, and active management is increasingly relevant to counter aggressive substance challenges.

Upgrade compliance, reporting and disclosure processes

Update tax reporting calendars and systems to capture new filing obligations: GloBE informational returns, local forms linked to transfer‑pricing disclosures and DAC8 crypto reporting (where applicable) may require new data feeds and earlier reconciliations. France’s administration has published filing timetables and e‑reporting guidance for affected entities. Allocate IT and tax resources now to avoid last‑minute remediation.

For non‑resident property owners, ensure that local property taxes (taxe foncière, taxe d’habitation on secondary residences where applicable) and IFI returns are timely and accurate; non‑residents remain liable for these taxes on property located in France and can be subject to penalties for late or incorrect filings. Confirm which French office (SIPNR or local service) manages notices for each asset.

Where automated reporting (platforms, custodians) intersects with your ownership chain, map data flows to confirm that beneficial‑ownership and transaction records reported to French or EU authorities are consistent with internal registers. Inconsistencies are a common audit trigger.

Prepare for audits and enforce rights, dispute prevention and response

Adopt a ‘pre‑audit’ posture: run focused health checks on documentation, valuations and treaty positions before French filings or transactions. This allows you to identify weaknesses and fix them with minimal exposure rather than reacting under formal examination. Where appropriate, obtain written tax opinions covering key points of interpretation.

If you face an assessment, use the available administrative mechanisms: prior rulings, APAs, mutual agreement procedures (MAP) under tax treaties and, where necessary, domestic litigation. The French tax administration publishes procedures for requests and the competent units for APA and dispute resolution. Early engagement with the administration often reduces escalation risk.

Keep a litigation contingency plan for high‑value exposures: preserve evidence, set aside reserves, and identify specialist counsel with experience in cross‑border French tax litigation. Real‑time coordination between tax, legal and treasury teams will materially improve the quality of the defence.

Practical implementation checklist and governance steps

Create a short, actionable checklist: 1) map assets and holding chains; 2) identify which reforms (GloBE, DAC8, IFI, TP) apply; 3) quantify exposures with tax & valuation modelling; 4) remediate structure or documentation gaps; 5) update filings and IT extracts; and 6) pre‑clear key items (APAs, rulings) where uncertainty is high. Prioritise items by monetary exposure and audit‑trigger likelihood.

Assign ownership and timelines: nominating a senior sponsor (CFO or GC) and a cross‑functional project lead reduces the chance of implementation slippage. Maintain a live risk register and schedule board‑level reporting of material tax policy changes and exposures.

Engage local advisers early: French filing nuances, valuation standards for IFI, and administrative practice (BOFiP guidance) evolve and are interpreted in audits. A French tax specialist can validate assumptions, draft defensible documentation, and handle local interactions with the DGFiP.

In addition to the checklist, run periodic compliance drills: simulate an information request or on‑site audit to test retrieval of master and local files, property valuations, and evidence of substance in holding entities. The cost of readiness is typically far lower than the cost of an adverse adjustment or penalty.

Finally, integrate tax‑change horizon scanning into governance: monitor BOFiP, Legifrance and EU tax directives for changes that could alter thresholds, reporting forms or the interpretation of rules. Staying current preserves optionality and reduces reactive restructuring.

France’s recent fiscal reforms increase transparency and tighten enforcement, but they also provide predictable legal frameworks when documented and planned properly. A disciplined combination of structure review, robust documentation, early engagement with authorities and strong governance will materially reduce risk for cross‑jurisdictional holdings and French property portfolios.

For actionable next steps, assemble the asset and entity map, commission targeted valuation and tax modelling, and schedule an advisory review with a French tax specialist to turn the high‑level checklist into a tailored implementation plan. Early, documented action will preserve value and limit disruption.
