BSPCE (Startup Share Warrants): Eligibility, French Tax Rules 2026 and Role of the Statutory Auditor

BSPCE — bons de souscription de parts de créateur d'entreprise, broadly equivalent to founder share warrants or startup stock options in French law — have become a central tool for equity compensation in the French tech ecosystem. Their legal framework (art. 163 bis G of the Code général des impôts, CGI) has remained broadly stable, but their tax treatment was significantly reformed by the Finance Acts for 2025 and 2026, most notably through the introduction of the new management packages regime (art. 163 bis H CGI). Understanding both frameworks is essential before issuing any BSPCE plan.

A preliminary note: BSPCE are not a one-size-fits-all retention mechanism. Their effectiveness depends on the company's cap table structure, the beneficiaries' tax situation, and — increasingly — the articulation with the new management packages rules. Professional advice from a registered accountant (expert-comptable) and a tax lawyer is strongly recommended before any attribution.

Quick summary: BSPCE are warrants granting eligible employees and executives the right to subscribe to shares at a price fixed on the grant date. They allow participation in the company's future value creation without immediate capital dilution. Tax on the gain depends on length of service (3-year threshold) and the reformed 163 bis H framework applicable from 15 February 2025.

BSPCE give the holder the right — not the obligation — to subscribe to shares at a predetermined exercise price. If the company's value increases, the beneficiary exercises the warrants, subscribes the shares at the original exercise price, and realises a gain equal to the difference between the exercise price and the market value of the shares at the time of sale.

Unlike free shares (actions gratuites) or large-company stock options, BSPCE are specifically designed for startups and innovative SMEs. No social charges arise on grant, no immediate dilution occurs, and the benefit is only crystallised when the holder actually exercises and sells the underlying shares.

Eligibility is subject to cumulative statutory conditions. The table below summarises the criteria under art. 163 bis G CGI. Verifying eligibility before any grant is a non-negotiable first step.

A holding company that owns an operational subsidiary may allow employees of that subsidiary to benefit from BSPCE, provided the subsidiary is held at least 75%. This point requires case-by-case analysis: the presence of investment funds (FCPI, FPCI) in the cap table can dilute the individual shareholders' percentage below the 25% threshold.

In the startup files we handle, the 25% individual ownership condition is the one most frequently at risk. When a new funding round brings institutional investors in, the cap table may no longer satisfy the threshold unless the structure has been anticipated. A cap table audit before any grant is standard practice in our firm.

Eligible beneficiaries are employees and executives who are subject to the employees' tax regime (régime fiscal des salariés) in the issuing company. This covers:

• SAS presidents and chief executive officers with employment or equivalent remuneration;
• Management board members and certain executive directors in SA;
• Employees on open-ended (CDI) or fixed-term (CDD) contracts in force at the grant date.

A non-employee partner — for example, a majority-manager gérant associé in an SARL — does not qualify. Freelancers, consultants, and service providers are excluded. These exclusions frequently catch founding teams off guard, particularly where co-founders hold different legal statuses within the group.

Employees and executives of subsidiaries held at least 75% may also receive BSPCE, subject to conditions. This is useful for structuring groups, but requires an analysis of the full ownership chain.

The exercise price is set freely by the company at the grant date, but it must not be below the fair value of the shares — at least to preserve the intended tax treatment and avoid requalification. In practice, the valuation used is typically that of the most recent funding round.

This is a sensitive area. The French tax authority (administration fiscale) may challenge an exercise price it considers artificially low, with the risk of requalifying the gain as salary income subject to income tax at marginal rates plus employer social charges. Robust documentation of the valuation methodology is therefore essential. A statutory auditor or independent valuator can contribute to securing this element, even though no specific auditor report is legally mandated for BSPCE as a matter of course.

The tax rules for BSPCE were substantially updated for securities subscribed from 1 January 2025 onwards. The table below sets out the applicable rates based on the beneficiary's length of service in the company at the time of disposal.

Key points to note:

The 12.8% flat tax (PFU) applies to the gain realised on disposal of the shares, not to any benefit arising on exercise of the warrant. The option for the progressive income tax scale may be advantageous for beneficiaries whose marginal tax rate is below 12.8% — for instance, employees early in their careers — but it requires a precise calculation at declaration stage.

Social levies at 18.6% reflect the increase in the CSG contribution (up 1.4 percentage points in 2026). This must be factored into any financial simulation provided to beneficiaries.

Worked example: An employee exercises BSPCE after 4 years of service. They subscribed 1,000 shares at an exercise price of €10, subsequently sold at €40 in a liquidity event. The gain is €30,000 (€30 × 1,000 shares).

• Under the flat tax (PFU): €30,000 × 12.8% = €3,840 income tax + €30,000 × 18.6% = €5,580 social levies = €9,420 total (31.4%).
• Had service been under 3 years (surcharge rate of 30%): €30,000 × 30% = €9,000 income tax + €5,580 = €14,580 total (48.6%).

The €5,160 difference on the same gain underlines why the length of service at the time of exercise matters so much in the design of any BSPCE plan.

The new management packages framework (art. 163 bis H CGI, introduced by the 2025 and 2026 Finance Acts and applicable to transactions from 15 February 2025) draws a distinction between:

• an acquisition or exercise gain, taxable in principle as salary income (progressive income tax scale plus social charges);
• a capital gains element, admitted under specific conditions: shares held at least 2 years, genuine risk of capital loss for the beneficiary, and a cap linked to a multiple of the initial investment.

The interaction between the specific BSPCE regime (art. 163 bis G) and the new management packages framework (art. 163 bis H) remains a matter of professional debate. Legal uncertainty is acknowledged by practitioners. It is also confirmed that BSPCE can no longer be held within a PEA or PEA-PME share savings plan.

Our assessment: this aspect must be presented with caution. The precise conditions under which art. 163 bis H applies to BSPCE, and the exact delineation of the gains affected, require a case-by-case review with a tax lawyer. Failing to address this risk in the documentation provided to beneficiaries is an advisory error with potentially significant financial consequences.

The grant of BSPCE requires formal corporate acts: an extraordinary general meeting (AGE) must authorise the issue, and the board or SAS president sets the terms of attribution by delegation. These decisions are documented in minutes and, where applicable, in statutory amendments.

A commissaire aux comptes (statutory auditor) may be involved in several ways:

• Exercise price valuation report if the company already has a CAC in place, in the context of reserved capital increase reports.
• Accounts certification if the company exceeds the statutory audit thresholds or if investors have required it under the shareholders' agreement.
• Standalone valuation engagement to secure the valuation underpinning the exercise price.

There is no statutory obligation to appoint a CAC solely to issue BSPCE. However, for companies that already have one, involving them in the valuation discussion is good practice and can reduce the risk of requalification by the tax authority.

The following checklist covers the verification steps that should be completed before any grant, in priority order:

1. Verify company eligibility: legal form, age below 15 years, IS tax regime, listing status, 25% individual ownership threshold.
2. Audit the cap table: check that current or future fundraising rounds will not push individual ownership below the required threshold.
3. Confirm each beneficiary's eligibility: tax status, connection to the company or its subsidiaries, social security regime.
4. Document the valuation: methodology used, comparable data, and where appropriate a report from an independent valuator or the CAC.
5. Draft the corporate documents: AGE minutes, board or president's resolution, attribution plan, individual award letters.
6. Inform the beneficiaries: model out the tax position based on projected length of service at the time of disposal; explain the genuine risk of capital loss.
7. Address the art. 163 bis H question: work with a tax lawyer to assess whether and how the capital gains element conditions can be met and documented.
8. Design vesting clauses carefully: the vesting period is freely set, but it should be aligned with the 3-year threshold for the favourable tax rate. Acceleration and forfeiture conditions must be explicit.

In our experience with startup files, the most consistently underestimated point is valuation documentation. BSPCE granted without a formalised valuation methodology expose the company to a tax reassessment, with the gain requalified as salary and employer social charges applied retroactively.

A BSPCE plan does not stand alone. French startups have access to several complementary tax tools that need to be considered together:

• The research tax credit (CIR) can represent a significant cash resource, usable to fund the technical team's salaries during development — see our article on the crédit d'impôt recherche.
• The executive remuneration strategy (salary versus dividends) affects available cash and company valuation — two parameters that directly influence the attractiveness of a BSPCE plan.
• The broader tax planning approach — choice of legal form, tax regime, distribution versus reinvestment — must be consistent with any equity incentive tool.

Our Paris team works alongside tech startups on all of these dimensions: tech startups.
