Private Equity Lawyers France 2026: LBO Interest‑deductibility Caps and Management‑package Changes

The Finance Act 2026 (Loi de finances pour 2026), adopted on 2 February 2026, has reshaped the economic calculus of leveraged buyouts in France by tightening interest‑deductibility caps on acquisition debt, clarifying the social‑security treatment of management packages, and introducing a new patrimonial‑holding surtax. For PE sponsors, fund counsel, CFOs, founders and management teams executing mid‑cap LBO structuring, these changes demand immediate adjustments to financial models, term‑sheet language and exit timelines. Private equity lawyers in France are now fielding a surge of re‑structuring enquiries, and understanding the practical options available, from debt push‑down redesigns to compliant management‑package architecture, is essential for any deal closing in the current cycle.

This guide delivers a transaction‑grade playbook covering the mechanics, risks and drafting responses that deal teams need right now.

Key takeaways for deal teams:

• Interest‑deductibility caps are narrower. The 2026 rules impose a stricter EBITDA‑ratio ceiling on related‑party acquisition finance, reducing the tax shield that sponsors have historically relied upon to boost IRRs.
• Management‑package social charges are clarified, and expanded. Gains from certain carried‑interest and ratchet instruments now attract employer and employee social contributions where defined thresholds are met.
• Patrimonial‑holding surtax targets holdco structures. A new surtax on predominantly patrimonial holding companies affects exit net proceeds and dividend cascading.
• Structuring responses exist. Debt push‑down, equity bridges, earn‑out redesigns and proactive URSSAF rulings can mitigate the impact, but only if implemented before closing.

Finance Act 2026, What Changed for Private Equity Lawyers in France and LBO Transactions

The Loi de finances pour 2026 represents the most consequential overhaul of French LBO tax economics since the ATAD transposition in 2019. Adopted by Parliament on 2 February 2026 and published on the official Legifrance portal shortly thereafter, the Act addresses three pillars that directly affect leveraged transactions: the deductibility of interest on acquisition debt, the fiscal and social treatment of management incentive packages, and the taxation of holding companies whose assets are predominantly patrimonial in nature.

Industry observers expect these changes to compress leveraged returns across the French mid‑cap segment by between 100 and 250 basis points on pre‑tax IRR, depending on gearing levels and hold periods. The likely practical effect will be a rebalancing of capital structures toward more equity and a renewed focus on operational value creation rather than financial engineering.

Timeline of key dates

The legislative context builds on the EU Anti‑Tax Avoidance Directive (ATAD) interest limitation rule already transposed into Article 212 bis of the Code général des impôts (CGI). The Finance Act 2026 narrows the scope of permissible deductions further by targeting related‑party financing specifically used in acquisition structures. For deal teams, the practical consequence is that the pre‑existing general interest limitation must now be read together with an additional, acquisition‑specific cap, creating a layered compliance obligation that requires careful modelling at the term‑sheet stage.

The management‑package provisions codify and, in several respects, supersede the administrative doctrine that had developed through successive rulings of the Conseil d’État and guidance from the tax authorities. The Act clarifies that gains realised on certain incentive instruments, including management equity strips, BSPCEs (bons de souscription de parts de créateur d’entreprise), and free shares (actions gratuites), may be recharacterised as employment income for social‑security purposes where specific value‑creation and vesting criteria are not demonstrably met.

LBO Interest‑Deductibility Caps, Mechanics, Scope and Worked Examples

The revised interest‑deductibility regime is the single most impactful change for sponsors structuring leveraged acquisitions in France. It operates as a supplementary cap, layered on top of the existing ATAD‑derived general limitation, and targets the specific debt raised by acquisition holdcos to finance share purchases.

Scope and application

The new cap applies to net borrowing costs, interest expenses minus interest income, incurred by any entity subject to French corporate income tax (impôt sur les sociétés) where those costs relate to indebtedness incurred, directly or indirectly, for the purpose of acquiring shares in another entity. The scope covers both intra‑group loans (from a parent, sister company or fund vehicle) and third‑party bank debt where the lending arrangement contains related‑party guarantees or is otherwise connected to a leveraged acquisition structure.

Holdcos created specifically for an LBO, the classic société holding d’acquisition, fall squarely within the provision. Operating subsidiaries whose debt is pushed down post‑acquisition are also caught, provided the borrowing can be traced to an acquisition purpose. The Act introduces a rebuttable “purpose test”: if more than 50% of a borrowing entity’s net borrowing costs relate to acquisition finance, the entire amount is subject to the new cap unless the taxpayer demonstrates that the non‑acquisition portion is genuinely separable.

This broad scope means that even bolt‑on acquisitions financed through existing group credit facilities may trigger the additional limitation where the financing is attributable to a share purchase. Private equity lawyers in France are advising clients to segregate acquisition‑purpose borrowing from operational revolving credit facilities at documentation stage to preserve deductibility on non‑acquisition debt.

Formula and cap mechanics

The Finance Act 2026 imposes a dual‑test ceiling. Acquisition‑related net borrowing costs are deductible only up to the lower of:

• 30% of the borrowing entity’s tax EBITDA (earnings before interest, taxes, depreciation and amortisation, calculated according to the methodology specified in Article 212 bis CGI and supplemented by BOFiP guidance); or
• A fixed monetary threshold (the level of which is expected to be confirmed in the forthcoming BOFiP administrative guidance, with early indications suggesting alignment with the existing €3 million safe harbour under the general ATAD rule, though applied separately to the acquisition tranche).

Excess interest that cannot be deducted in the current year may be carried forward for a maximum of five financial years, subject to the same dual‑test ceiling being applied in each subsequent year. Critically, the carry‑forward stock must be separately tracked from any excess interest arising under the general interest limitation, creating a dual‑register compliance obligation.

Worked example, mid‑cap LBO tax impact

Consider a mid‑cap LBO with the following parameters:

A second scenario at 50% gearing (€75 million debt, €4.125 million annual interest) shows a more modest impact: approximately €525,000 of excess interest per year and an IRR reduction of roughly 90 bps. A third scenario at 70% gearing (€105 million debt, €5.775 million annual interest) amplifies the effect significantly, with approximately €2.175 million of annual excess interest and an IRR impact exceeding 250 bps.

The message for sponsors is clear: higher leverage ratios face disproportionately greater tax friction under the new rules. Financial models must be re‑run with the dual‑test ceiling before any term sheet is signed.

Management Packages After 2026, Tax and Social Security Treatment

The management‑package provisions of the Finance Act 2026 resolve several long‑standing ambiguities that had generated significant litigation risk, but they do so at the cost of broader social‑security exposure for management teams. For private equity lawyers advising on French LBOs, package design has become a front‑loaded exercise that must be completed before term‑sheet execution, not after.

Tax changes and legislative references

The Act codifies a two‑tier classification framework for management incentive gains. Where the gain on an instrument (BSPCEs, free shares, management equity strips, or ratchet mechanisms) can be demonstrably attributed to value creation occurring during the manager’s service period, and the instrument satisfies defined conditions relating to vesting schedules, exercise mechanics and fair‑market‑value pricing at grant, the gain continues to benefit from capital‑gains taxation under the prélèvement forfaitaire unique (PFU) at 30% (12.8% income tax plus 17.2% social levies on investment income).

Where those conditions are not met, however, the gain is recharacterised as a salary supplement (complément de salaire) and subjected to the progressive income‑tax scale (up to 45% marginal rate plus an additional 4% contribution on high incomes). The boundary between the two tiers turns on documentation: the issuer must produce a contemporaneous valuation report at grant, a schedule demonstrating that the exercise price reflected fair market value, and evidence that the vesting period aligned with genuine operational milestones.

Social security (URSSAF/ACOSS) treatment and practical compliance

The more consequential change for many deal teams is the expansion of social‑security exposure. Under the Act, where a management‑package gain is recharacterised as a salary supplement, both employer and employee social contributions apply, at combined rates that can exceed 65% of the gain (employer charges approximately 45%; employee charges approximately 22%, subject to applicable ceilings). Even where the gain retains capital‑gains characterisation, the Act introduces a new reporting obligation requiring employers to disclose management‑package grants and exercises to URSSAF within 60 days of the triggering event.

Early indications from market practice suggest that URSSAF is expected to issue updated circulars detailing the thresholds, reporting templates and audit priorities for management packages during Q2 2026. Proactive engagement with URSSAF, through formal ruling requests (rescrit social), is increasingly regarded as essential for any material package. A ruling request typically takes three to four months and provides legal certainty for the employer on contribution obligations, provided the facts disclosed are accurate and complete.

Design checklist for compliant management packages

• Contemporaneous valuation. Obtain an independent valuation report at the date of grant, referencing standard methodologies (DCF, comparable transactions, precedent multiples).
• Fair‑market‑value exercise price. Document that the exercise or subscription price reflects fair value, avoid deep discounts without economic justification.
• Operational vesting milestones. Tie vesting to operational KPIs (revenue growth, EBITDA margin, cash conversion) rather than purely financial triggers (IRR, multiple of money).
• URSSAF reporting. Implement an internal calendar for the 60‑day reporting obligation on grants and exercises.
• Proactive ruling request. For packages exceeding €500,000 in potential gain per beneficiary, submit a rescrit social to URSSAF before grant execution.
• Sample clause (term sheet): “Management Incentive Plan: The Sponsor and Management agree that all incentive instruments shall be designed and documented to satisfy the conditions for capital‑gains treatment under the Finance Act 2026 provisions. The Company shall obtain an independent valuation at grant and shall submit a rescrit social to URSSAF within [30] days of Board approval of the Plan.”

Mid‑Cap LBO Structuring Playbook, Mitigation Strategies for Sponsors

The tightened interest‑deductibility regime does not eliminate leverage as a tool, but it requires sponsors and their advisers to redesign capital structures with greater precision. The following strategies represent the principal responses being deployed by private equity lawyers in France in the current deal cycle.

Debt push‑down, legal and tax steps, risks

Debt push‑down, merging the acquisition holdco into the operating target so that operating EBITDA supports interest deductions, remains viable but faces heightened scrutiny. The Finance Act 2026 does not prohibit upstream or downstream mergers, but the “purpose test” means that post‑merger interest costs attributable to acquisition debt continue to be subject to the acquisition‑specific cap for a look‑back period (expected to be confirmed in BOFiP guidance, with early market expectation of three to five years).

To preserve deductibility, sponsors should ensure that the merger has genuine commercial substance beyond tax optimisation, for example, operational synergies, simplification of reporting, or elimination of intercompany royalties. Transfer pricing documentation must demonstrate arm’s‑length terms for any remaining intercompany financing. Lenders should be briefed early, as covenant calculations may need recalibration to reflect the merged entity’s adjusted EBITDA under the new rules.

Equity bridges and earn‑outs

Where the new interest cap makes high gearing uneconomic, sponsors are increasingly using equity bridge facilities, short‑term loans structured as quasi‑equity that convert into permanent equity within 12 to 18 months of closing. The interest on genuine equity bridges falls outside the acquisition‑debt scope once conversion occurs, provided the conversion is economically real and not a circular arrangement.

Earn‑outs linked to post‑acquisition performance offer a complementary tool. By deferring a portion of the purchase price and linking it to EBITDA targets, sponsors reduce the quantum of upfront debt and, consequently, the annual interest burden subject to the new cap. Drafting earn‑out provisions requires careful attention to the common elements of a term sheet and to the interaction between earn‑out payments and the new patrimonial‑holding surtax (see below).

Holdco and patrimonial‑holding designs, surtax mitigation

The new patrimonial‑holding surtax targets companies whose assets are more than 50% composed of financial participations, real estate or other non‑operational assets. For classic LBO holdcos, which by definition hold shares in the target and little else, this creates a direct exposure. Mitigation options include embedding genuine operational functions within the holdco (management services, treasury, IP licensing) and ensuring that asset‑composition tests are met on a look‑through basis.

Some sponsors are exploring dual‑holdco architectures, with an operational services company sitting between the fund vehicle and the acquisition holdco, to inject economic substance. However, the Act’s anti‑avoidance provision, which allows the tax authorities to disregard structures lacking genuine economic activity, means that paper‑thin arrangements will not survive audit.

Intercreditor and covenant drafting points

Term sheets should include an express covenant requiring the borrower to maintain separate accounting registers for acquisition‑specific and general interest carry‑forwards. Intercreditor agreements should address the priority of debt‑service payments in a scenario where the tax shield is reduced, potentially triggering cash‑sweep or mandatory prepayment events earlier than originally modelled.

Exit Planning France, Seller and Management Reinvestment Under Article 150‑0 B Ter

Exit planning in France requires careful navigation of the apport‑cession regime codified in Article 150‑0 B ter of the CGI. This provision permits sellers to defer capital‑gains tax on share disposals where the proceeds are reinvested into qualifying economic activities within defined timelines. For PE sponsors and management teams, the regime is a critical tool for structuring secondary buyouts, management buy‑ins and partial exits.

Article 150‑0 B ter, current regime, mechanics and traps

Under Article 150‑0 B ter, a seller who contributes shares to a holding company controlled by that seller can defer the capital gain arising on the contribution, provided that (a) the holding company reinvests at least 60% of the disposal proceeds into eligible economic activities within two years, and (b) the reinvestment assets are held for at least 12 months. Eligible economic activities include operating businesses, venture capital or private equity fund commitments, and certain real estate development activities.

The principal traps include: failure to meet the two‑year reinvestment deadline (which crystallises the deferred gain plus late‑payment interest); reinvestment into ineligible assets (passive financial instruments, listed securities held for trading); and premature disposal of the reinvestment assets within the 12‑month holding period. Documentation must be meticulous, the seller’s holding company must maintain a dedicated reinvestment tracking register, and annual reporting to the tax authorities is mandatory. For further context on managing cross‑border asset disposals, see the guide on why disclosure letters are crucial in M&A deals.

Timing, valuation and documentation checklist

• Pre‑exit valuation. Obtain an independent valuation of the contributed shares at the date of contribution, this determines the deferred gain and must withstand audit scrutiny.
• Reinvestment pipeline. Identify and pre‑approve reinvestment targets before the exit closes; two years passes quickly, and deal sourcing under time pressure increases execution risk.
• Holding period monitoring. Calendar the 12‑month minimum holding period for each reinvestment asset; premature disposal triggers full gain recognition.
• Annual reporting. File the required annual declaration (formulaire n° 2074‑I or equivalent) with the seller’s personal income‑tax return, disclosing the status of reinvestments and confirming continued compliance.
• Exit timing and realistic horizons. Industry observers typically note that French mid‑cap LBO hold periods range from four to six years. Given the new interest‑cap economics, some sponsors are expected to extend hold periods to allow additional operational value creation to offset reduced leverage returns. Management teams should align vesting schedules and liquidity expectations accordingly.

Quick Compliance Checklist and Negotiation Tips for Counsel

The following checklist consolidates the due‑diligence, tax, social‑security and drafting actions that counsel should address on every French LBO transaction closing under the Finance Act 2026 regime.

• Financial model stress test. Re‑run the acquisition model with the dual‑test interest cap applied; scenario‑test at 30%, 50% and 70% gearing.
• Debt segregation. Ensure acquisition‑purpose debt is documented separately from operational revolving facilities; maintain a dual‑register carry‑forward tracker.
• Management‑package compliance. Complete the design checklist (contemporaneous valuation, FMV pricing, operational milestones, URSSAF reporting calendar, rescrit social where material).
• Patrimonial‑holding test. Assess whether the holdco’s asset composition exceeds the 50% patrimonial threshold; embed operational substance or restructure if necessary.
• Transfer pricing documentation. Update intercompany financing agreements to reflect arm’s‑length terms; document the business rationale for any intra‑group loans.
• Warranty and indemnity drafting. Include a specific tax indemnity for interest‑deductibility shortfall risk. Sample clause: “The Seller shall indemnify the Buyer against any Tax Liability arising from the disallowance of interest deductions on the Acquisition Debt to the extent that such disallowance results from a change in classification of the Acquisition Debt under Articles 212 bis or [new article reference] of the CGI occurring after Completion, net of any carry‑forward benefit realised within [5] years.”
• Escrow and retention. Consider a tax‑specific escrow retention of 5–10% of the purchase price, releasing upon expiry of the statute of limitations for the relevant tax years.
• Post‑close monitoring. Calendar BOFiP guidance releases, URSSAF circulars and any amendments to implementing regulations; update covenant calculations and reporting systems accordingly.
• Minority protections. For co‑investment structures, ensure minority shareholders’ protections address the new tax risks, including information rights on interest‑deductibility filings and management‑package reporting.

Conclusion, Recommended Next Steps for Private Equity Lawyers in France

The Finance Act 2026 has fundamentally altered the cost‑of‑leverage equation for LBOs in France. Sponsors who fail to re‑model their capital structures risk material IRR compression, and management teams who do not proactively design compliant incentive packages face unexpected social‑security liabilities. The practical responses outlined in this guide, debt push‑down with genuine substance, equity bridge conversion, earn‑out structures, proactive URSSAF engagement, and meticulous Article 150‑0 B ter exit planning, represent the essential toolkit for deal teams operating in the current environment.

The most effective approach is to treat these changes as front‑loaded compliance obligations: address them at term‑sheet stage, not post‑closing. Private equity lawyers in France should be engaged from the earliest structuring discussions to ensure that financial models, package designs and transaction documentation reflect the new rules from day one. Those looking to structure or restructure transactions under the new regime should consult experienced PE counsel through the Global Law Experts lawyer directory. For sponsors evaluating how to start an investment fund, early integration of the new French tax parameters into fund‑formation documents is equally important.
