The convergence of France’s Loi de finances pour 2026 and the OECD’s global minimum tax framework under Pillar Two represents one of the most significant legislative inflection points for cross-border wealth holders and multinational holding structures in recent memory. Taken individually, each reform would already demand careful re-examination of existing arrangements. Taken together, they create a layered compliance environment in which structures that were entirely defensible two years ago may now generate unexpected tax liabilities, reporting obligations, or reputational exposure.

For corporate groups, family offices, trustees, and high-net-worth individuals with French connections, whether as residents, non-residents holding French assets, or shareholders in French-linked entities, the window for proactive restructuring is narrowing. This article provides a structured overview of the key legislative changes, their practical implications for cross-border wealth and holding arrangements, and the planning levers that remain available under French and international law.

The 2026 finance act: a paradigm shift for cross-border tax planning

The Loi de finances pour 2026, adopted by the French Parliament in early 2026, marks the most consequential shift in international tax policy in over a decade for cross-border wealth holders. The legislation does not represent a single targeted reform but rather an interlocking set of measures that collectively tighten the fiscal environment for both individuals and entities with French nexus. Understanding its architecture is the prerequisite for any credible planning exercise.

The legislation simultaneously extends the exceptional contribution on high incomes, introduces a new tax targeting non-operational assets held through holding companies, transposes DAC9 reporting obligations for trustees and intermediaries, and completes France’s domestic implementation of the OECD Pillar Two global minimum tax framework. Each of these pillars interacts with the others in ways that can amplify the overall tax burden on structures that straddle multiple jurisdictions.

The 2026 Finance Bill introduces significant changes that will reshape taxation in France, with measures ranging from higher levies on multinationals to revised exemptions, revealing the fiscal direction France is taking for 2026. For advisers and their clients, the starting point must be a comprehensive mapping of existing structures against each of these new provisions before any restructuring decision is made.

The minimum tax on high-income earners: scope and strategic implications

The 2025 Finance Act introduced a minimum taxation mechanism, the CDHR, for taxpayers whose household income exceeds €250,000 for single individuals or €500,000 for joint filers, ensuring a minimum effective tax rate of 20% where their effective rate would otherwise fall below that threshold. This mechanism was not a temporary measure designed to address a one-year fiscal shortfall.

The 2026 Finance Law renewed the CDHR and extended it until France’s public deficit drops below 3% of GDP. Given France’s current fiscal trajectory, this effectively transforms what was presented as an exceptional contribution into a structural feature of the French tax landscape for the foreseeable future. High-income taxpayers, including executives of multinational groups, founders of technology companies, and individuals with significant investment income, must now plan on the basis that this minimum rate is permanent.

Single taxpayers with reference income exceeding €250,000 and couples exceeding €500,000 continue to face a surcharge of 3% on the portion between these thresholds and €500,000 / €1,000,000 respectively, rising to 4% above those ceilings. The cumulative effect of the CDHR, the progressive income tax scale, and these surcharges means that the marginal effective rate for high earners in France now comfortably exceeds 60% in a number of configurations, making the optimisation of income characterisation, timing, and sourcing more important than ever.

The new levy on patrimonial assets held through holding companies

One of the most structurally disruptive innovations of the 2026 Finance Act is the introduction of a specific tax on non-operational assets held through holding companies. An initial plan for a broad 2% tax on the non-operating assets of family holding companies was recentred into a 20% tax on luxury assets held in passive holdings. While the final scope is narrower than originally proposed, its implications for family groups and private-equity-style holding vehicles remain significant.

The tax applies at a rate of 20% to the company’s share of net income attributable to those patrimonial assets, distinct from the standard corporate income tax. This creates a sui generis charge that sits alongside, rather than replacing, existing corporate income tax obligations, potentially resulting in double taxation of income generated by assets such as real estate, art collections, yachts, or other luxury items held at the level of an intermediate holding entity.

The tax applies where the market value of all assets reaches or exceeds €5 million. Holding groups that have historically aggregated diversified asset classes within a single vehicle for administrative simplicity will need to assess whether disaggregation, asset transfers, or reclassification can reduce exposure without triggering the abuse-of-law provisions that have been simultaneously reinforced. The interaction with the IFI real estate wealth tax, which remains unchanged, with its threshold at €1.3 million and rates from 0.5% to 1.5%, must also be carefully modelled.

Pillar Two and the global minimum tax: consequences for French-linked holding structures

France’s transposition of the OECD Pillar Two framework into domestic law is a critical development for multinational groups with French parent entities, French intermediate holding companies, or significant French operations. The Finance Bill for 2025, approved by the French Parliament, revised Pillar Two Global Anti-Base Erosion (GloBE) rules transposed into French domestic law, affecting corporations with regard to corporate income tax, merger transactions and dividend withholding.

The GloBE rules impose a 15% minimum effective tax rate on the profits of multinational enterprise groups with annual revenues of at least €750 million, measured on a jurisdiction-by-jurisdiction basis. Where a constituent entity’s effective tax rate in a given jurisdiction falls below 15%, a top-up tax is collected, either by France as the jurisdiction of the ultimate parent entity (under the Income Inclusion Rule) or by other jurisdictions (under the Undertaxed Profits Rule). For groups that have structured their operations to benefit from preferential regimes in low-tax jurisdictions, the Pillar Two framework fundamentally alters the economics of those arrangements.

Holding structures that route dividends, royalties, or capital gains through jurisdictions offering participation exemptions, patent boxes, or reduced withholding tax rates must now be re-evaluated in light of the GloBE effective tax rate calculation. Substance requirements, the treatment of deferred tax assets and liabilities, and the interaction between Pillar Two and existing double tax conventions all require specialist analysis. French groups in particular must assess whether their existing holding architecture generates top-up tax exposure and, if so, whether restructuring prior to the first GloBE reporting deadlines is both feasible and advisable.

DAC9 reporting obligations: new transparency requirements for trustees and intermediaries

Trustees and fiduciaries face new DAC9 reporting obligations, due-diligence steps, and penalty exposure under the 2026 Finance Act. DAC9, the ninth iteration of the EU Directive on Administrative Cooperation, extends automatic exchange of information to cover the Pillar Two GloBE information return, ensuring that tax authorities across the EU have access to the same data submitted by multinational groups to their primary filing jurisdiction.

For trustees administering international trusts with French beneficiaries, French-sited assets, or French settlors, the DAC9 framework adds a further layer of reporting complexity on top of the existing obligations under the French trust disclosure regime (Article 1649 AB of the General Tax Code). The penalties for non-compliance are substantial and can attach not only to the trustee but also to intermediaries who assisted in establishing or maintaining the structure. A proactive review of reporting calendars, data-collection procedures, and the scope of existing disclosures is therefore an immediate priority.

Beyond DAC9, the broader trend toward transparency, encompassing the UBO register, the DAC6 mandatory disclosure regime for cross-border arrangements, and the FATCA/CRS reporting frameworks, means that the era of opacity in cross-border wealth structuring is definitively over. Structures must now be designed and maintained on the assumption that all relevant information will be visible to French and foreign tax authorities alike. This does not eliminate the scope for legitimate planning, but it does require that every structural choice be defensible on substantive economic grounds.

The Dutreil pact: tightening of the family business transfer exemption

Transfers of family businesses will now exclude non-professional assets from the Dutreil tax exemption, a measure designed to prevent tax abuse and ensure the pact benefits genuine business transfers. This reform has significant implications for family groups that have historically used holding companies to aggregate both operational and non-operational assets, relying on the Dutreil exemption to pass the entire vehicle to the next generation at a 75% reduction in gift and inheritance tax.

Under the revised rules, the portion of the holding company’s value attributable to non-professional assets, including real estate held for personal use, financial investments, and other patrimonial items, will no longer qualify for the Dutreil reduction. This requires families to reassess the composition of their holding vehicles well in advance of any planned transfer. In many cases, the most efficient solution will involve separating operational assets from patrimonial assets into distinct legal entities, each governed by an appropriate ownership and governance structure.

The interaction between the Dutreil reform and the new patrimonial-asset levy described above creates a compounding effect for mixed-asset holding companies. Assets that were previously sheltered by the Dutreil exemption on transfer may now also generate a 20% annual charge at the holding level if they qualify as luxury or non-operational assets. Families that delay restructuring risk being caught by both provisions simultaneously, making early action a matter of considerable financial significance.

Exit tax and the mobility of high-net-worth individuals

High-net-worth individuals and expatriates face changes to French taxation rules, including the exceptional contribution, social charges, and exit tax triggers, requiring immediate pre-move planning steps. France’s exit tax regime (Article 167 bis of the General Tax Code) subjects departing residents to immediate taxation on unrealised capital gains embedded in shareholdings above certain thresholds, with deferral available only under strict conditions and subject to guarantee requirements.

The 2026 Finance Act does not fundamentally restructure the exit tax mechanism, but the extension of the CDHR and the introduction of the patrimonial-asset levy create stronger incentives for high-net-worth individuals to consider relocating their tax residence outside France. This in turn elevates the importance of exit tax planning, since a poorly structured departure can trigger an immediate and substantial tax charge on gains that have not yet been realised in cash. The timing of the departure, the composition of the shareholding portfolio, and the destination jurisdiction’s treaty position with France are all critical variables.

For non-residents who hold French assets, particularly real estate subject to the IFI, the 2026 environment requires a careful assessment of the overall French tax footprint. Proper ownership structures, debt planning, and coordinated cross-border financial planning can help reduce French wealth tax exposure. However, such planning must be implemented well in advance of any triggering event, since retroactive restructuring is both legally precarious and practically difficult once French tax authorities have opened an inquiry.

Restructuring holding structures: available levers and abuse-of-law risks

The legislative changes described above create both the need and the opportunity to restructure existing cross-border holding arrangements. The available levers include the disaggregation of mixed-asset holding companies, the insertion of intermediate holding entities in jurisdictions offering genuine economic substance and favourable treaty networks, the conversion of passive income streams into active business income, and the optimisation of debt financing to reduce taxable bases at the level of French entities.

However, each of these levers must be deployed with careful attention to the French abuse-of-law doctrine (abus de droit) and the general anti-avoidance rule (GAAR) transposed from the EU Anti-Tax Avoidance Directive. Holding companies and family groups must navigate the patrimonial-asset tax, Pillar Two top-up mechanics, and restructuring options that can be implemented without triggering abuse-of-law challenges. A restructuring that lacks genuine economic substance, or that is implemented solely for tax purposes, is vulnerable to challenge, with consequences that include the reassessment of the tax avoided, interest, and penalties of up to 80% of the amounts at stake.

The standard of substance required to withstand scrutiny has risen materially in recent years, driven by a combination of legislative reform, judicial decisions, and the increased information available to tax authorities through automatic exchange mechanisms. Holding companies must now demonstrate genuine decision-making capacity, qualified personnel, adequate physical premises, and meaningful economic activity in their jurisdiction of incorporation. Letterbox structures, nominee directors, and circular financing arrangements are no longer viable in any jurisdiction that wishes to maintain its treaty network and its reputation with the OECD and the EU.

Dividend withholding tax: implications for cross-border income flows

The general scope of the withholding tax has been extended to dividends and assimilated income whose beneficial owners do not have their tax residence or corporate seat in France. This extension has direct consequences for holding structures that route French-source dividends to non-resident parent entities or beneficial owners. Groups that have historically relied on reduced withholding tax rates under double tax conventions or the EU Parent-Subsidiary Directive must verify that their structures continue to meet the beneficial ownership and anti-abuse requirements that condition access to those reduced rates.

The beneficial ownership analysis has become increasingly granular in French administrative practice and judicial decisions. A non-resident entity that receives French dividends must demonstrate that it has the legal and economic capacity to use and enjoy those dividends freely, without being contractually or de facto obliged to pass them on to another party. Conduit arrangements, back-to-back financing structures, and entities with no genuine economic function in the dividend chain are at heightened risk of challenge under both domestic anti-abuse rules and the treaty-shopping provisions of the OECD’s Multilateral Instrument.

For family groups and private-equity structures with French portfolio companies, the practical implication is a need to review the entire dividend waterfall from the French operating entity to the ultimate beneficial owner. Each intermediate entity must be assessed for substance, beneficial ownership, and treaty eligibility. Where gaps are identified, remediation, whether through consolidation, substance enhancement, or route modification, should be implemented before the next dividend distribution cycle.

Strategic recommendations for advisers and their clients

The cumulative effect of the 2026 Finance Act measures and the Pillar Two framework is to raise both the cost and the complexity of maintaining cross-border wealth and holding structures with French connections. For advisers, this creates an imperative to conduct comprehensive structural audits for all clients with material French exposure, covering income tax, wealth tax, withholding tax, transfer tax, and Pillar Two dimensions simultaneously. Siloed analysis, addressing each issue in isolation, is no longer adequate given the interactions between the different regimes.

For clients, the key message is that the window for proactive restructuring remains open but is closing. Measures implemented before the relevant triggering events, a dividend distribution, a business transfer, a change of residence, a Pillar Two top-up assessment, can substantially reduce the overall tax burden and eliminate penalty exposure. Measures implemented after those events are typically more limited in their effect and more vulnerable to challenge. The cost of early action is almost invariably lower than the cost of reactive remediation.

Specific priorities include: reviewing the asset composition of holding companies against the new patrimonial-asset levy; assessing Dutreil eligibility in light of the non-professional asset exclusion; mapping Pillar Two effective tax rates across all jurisdictions in which the group operates; verifying DAC9 and DAC6 reporting obligations and deadlines; and stress-testing the beneficial ownership and substance position of all non-resident entities in the dividend chain. Each of these exercises requires specialist tax expertise and, in most cases, close coordination between French and foreign advisers.

France’s legislative trajectory is consistent with a broader international movement toward higher effective taxation of mobile capital and cross-border structures. The OECD’s Base Erosion and Profit Shifting project, the EU’s successive DAC directives, and the Pillar Two framework all reflect a political consensus, at least among OECD and EU member states, that the era of aggressive international tax planning is over. Within this environment, the role of specialist tax counsel is not to identify ways to circumvent the new rules, but to ensure that legitimate planning opportunities are identified, properly documented, and implemented in a manner that is both legally sound and sustainable over time.
