As France enacted its Finance Act for 2026, executives and non-resident high-net-worth individuals face a materially different domestic tax landscape: new levies on holding-company patrimony and adjustments to the flat-taxation regime alter the economics of onshore ownership and interposed holding structures.

At the same time, multinational tax reform under the OECD’s Pillar Two and an expanded EU transparency and crypto rulebook (DAC8/CARF and MiCA) are reshaping cross-border risk, reporting burdens and the treatment of digital assets, making coordinated wealth, compensation and property planning urgent and operational.

Assess the impact of France’s 2026 finance law

Begin with a fact-based diagnostic of how the Finance Act 2026 affects the taxable base of holding companies and the taxation of financial and real-estate assets held through corporate wrappers. Executives should not rely on pre-2026 assumptions: several provisions explicitly target patrimonial holdings and adjust social contributions and withholding regimes.

Quantify immediate exposures: determine whether a holding company now falls within the new asset-based tax thresholds, whether the rise in social contributions increases effective tax on investment income, and whether any grandfathering or reporting transitional rules apply to existing structures. Use balance-sheet and market-value tests rather than nominal book values when modelling exposures.

Identify quick-win adjustments that preserve economic objectives while reducing tax friction, for example, trimming non-operating asset positions, consolidating redundant entities, or adjusting payout policies, but only after assessing anti-avoidance rules and exit tax rules that may generate immediate or deferred tax costs.

Review and restructure ownership for tax efficiency

Executives with concentrated holdings should prioritise a clean, well-documented ownership map that shows legal title, beneficial ownership and the tax residence of each legal vehicle and key individual. This mapping is the foundation for defensible structures before tax authorities and courts.

Consider moving passive assets out of entities now exposed to the patrimonial holding tax where economically feasible, using properly capitalised special-purpose vehicles in favourable jurisdictions, but only where substance, governance and transfer-pricing are credible and documented to avoid recharacterisation and anti-abuse challenges.

Where movement of assets is unrealistic, evaluate in-place mitigations: consolidation of operating activities into separate entities, documented service-level agreements, and tightening of group intragroup financing terms to reflect real economic flows and reduce perceived artificiality.

Protect real estate and property holdings

Real estate frequently drives holding-company patrimonial thresholds. For property held in France, review the legal vehicle (private company, SCI, direct ownership) and the resulting French tax base, social levies and reporting obligations, and model the impact of the Finance Act’s changes on disposal and succession scenarios.

Consider targeted operational changes: (i) isolate income-producing property into operating companies where appropriate, (ii) ensure market rents and third-party arrangements where groups lease to one another, and (iii) update long-term estate and succession plans to reflect new taxation on non‑professional assets and potential inheritance-tax interactions.

Where cross-border elements exist (foreign-located properties owned by French-resident controlling persons or vice versa), revisit treaty protections, permanent-establishment risks and withholding tax positions to avoid surprise exposure on repatriation or transfer of title.

Revisit executive compensation and equity plans under Pillar Two

Pillar Two (the GloBE rules) introduces a global minimum effective tax mechanism for large groups and creates new compliance, reporting and potential top-up tax liabilities that can indirectly affect executives, notably in multinational stock-based compensation, intercompany service arrangements and deferred compensation structures.

Executives and boards must reassess equity plan design: determine whether RSUs, stock options, phantom plans or cross-border remuneration give rise to jurisdictional mismatches or incremental top-up taxes under the Income Inclusion Rule (IIR) or Undertaxed Profits Rule (UTPR). Where necessary, redesign awards to align tax outcomes with intended economic exposure.

Coordinate tax and accounting teams early: Pillar Two requires new information returns and jurisdictional effective tax rate calculations. Advance modelling of expected top-up allocations, domestic top-up tax (QDMTT) options, and safe-harbour elections can materially reduce both cash surprise and compliance cost.

Manage crypto exposures and reporting obligations

EU crypto rules, MiCA for market conduct and authorisation and DAC8/CARF for tax reporting, have introduced a new compliance layer for holders, service providers and intermediaries; CASPs now face authorisation and detailed user-reporting duties while tax authorities will receive systematic transaction data.

Executives holding meaningful crypto positions should (i) centralise and reconcile all exchange, custody and private-key exposures; (ii) establish audit-ready records connecting wallet addresses to beneficial owners; and (iii) evaluate counterparty compliance status (MiCA authorisation or national equivalence) to anticipate where reporting will flow and when.

Note the operational deadlines and transitional rules: MiCA’s regulatory framework and DAC8’s CARF reporting have specific authorisation and reporting start dates that affect existing providers and users; failure to align record-keeping to those deadlines can create disclosure gaps and audit risk.

Strengthen documentation, compliance and cross-border defence

Given the twin forces of domestic tax tightening and global transparency, the single most reliable defence is contemporaneous, commercial documentation: clear minutes, economic analyses, independent valuations and third‑party agreements demonstrating that structures were driven by bona fide commercial or investment rationales.

Invest in robust compliance processes: upgrade KYC and source-of-funds documentation, strengthen transfer-pricing policies if intragroup finance or services are used, and implement a consistent reporting calendar for international information returns, including Pillar Two GloBE filings where applicable.

Engage qualified advisers early, cross-disciplinary teams of tax lawyers, transfer-pricing specialists, trust/estate advisers and forensic accounting experts, to prepare defensible positions for audits or litigation and to structure pragmatic remediation where legacy arrangements no longer meet the new legal or transparency thresholds.

Practical next steps for executives and families

1) Commission a full-scope diagnostic that maps all legal entities, assets (including crypto), compensation arrangements and intercompany flows; include valuation of property and mark-to-market positions for assets that drive the new patrimonial thresholds.

2) Prioritise changes that are low-cost and low-disruption yet high-impact (e.g., governance, documentation, contractual clean-up), and stage structural moves that trigger exit taxes or transfer costs to optimise timing across fiscal years.

3) Implement ongoing governance: quarterly tax-health reviews, a secure repository of evidentiary documents, and escalation protocols for new transactions that might interact with Pillar Two, DAC8/CARF or MiCA obligations.

4) Finally, prepare a communications plan for shareholders and beneficiaries explaining why changes are required, the expected tax impact, and how the firm will preserve long-term wealth objectives while meeting regulatory obligations.

France’s 2026 Finance Act, Pillar Two and the EU crypto rulebook are not theoretical risks, they materially change incentives, reporting responsibilities and the cost of offshore or onshore structuring. Decision-makers should act now, with coordinated legal, tax and compliance advice, to shore up executive wealth and property holdings in a defensible, documented and economically sensible way.

For bespoke planning, particularly where cross-border entities, substantial real estate or significant crypto positions are present, retain specialised tax counsel able to coordinate Pillar Two modelling, MiCA/DAC8 readiness and French domestic-law mitigation to preserve value and reduce audit risk.
