BSA, BSPCE, AGA: which employee incentive mechanism should you choose in 2026?

BSA, BSPCE, AGA: the right mechanism at the right time

To attract and retain talent, French startups use three main employee equity mechanisms: BSPCE, BSA and AGA. The right choice depends on the company’s age and legal form, the beneficiaries’ profiles, the objective (recruitment, retention or performance) and tax/social contribution constraints. This article offers a practical, up-to-date comparison (2026), followed by an operational method for rolling out your plan without unpleasant surprises.

Essential legal reminders

BSPCE (Bons de Souscription de Parts de Créateur d’Entreprise)

• Legal/tax basis: Code général des impôts, art. 163 bis G (Legifrance).
• Company eligibility (2026): a company limited by shares (SAS, SA, SCA), subject to corporate income tax in France or the EU/EEA with a tax treaty, established less than 15 years ago, not resulting from a merger or equivalent restructuring, with a minimum proportion of capital held by individuals (reduction to 15% confirmed by the 2026 Finance Act) (De Pardieu Brocas Maffei — 2026 Finance Act ; Legifrance).
• Beneficiaries: employees and corporate officers treated as employees of the company and, subject to conditions, its subsidiaries/control chain (scope extended by recent Finance Acts) (Legifrance; 2026 Finance Act).
• Governance: authorisation by an extraordinary general meeting (EGM) and plan rules specifying volume, price, vesting schedule and exercise/departure conditions (Service Public Pro).
• Beneficiary taxation: tax arises when the shares resulting from the warrants are sold. A flat income-tax rate of 12.8% applies if service ≥ 3 years at the sale date, otherwise 30%, in both cases with 17.2% social levies (PFU) (CGI, art. 163 bis G; practical summary Legalstart 2026).

Quick example: 10,000 BSPCE with a €1 exercise price, shares resold for €10 after 3 years of service. Net taxable gain = (10 - 1) × 10,000 = €90,000, taxed at 12.8% + 17.2%.

BSA (Bons de Souscription d’Actions)

• Legal basis: compound securities (warrants) — Code de commerce, in particular art. L.228-91 et seq. (issuance decided by the EGM) (Legifrance).
• Eligibility: any company limited by shares (no age limit). Very broad beneficiary scope (employees, officers, consultants, partners and investors).
• Tax/social contributions: no specific preferential regime. The gain depends on the route taken (resale of the BSA or subscribed shares). For employees, an exercise/subscription price disconnected from actual value may lead to reclassification as a benefit in kind subject to social contributions and income tax as salary. This makes a robust independent valuation and genuine economic risk essential (AMF; comparative analysis Equify).
• Governance: EGM resolution, exercise conditions (price, period and liquidity events) and, ideally, organisation of the body of holders for collective decisions (Code de commerce, L.228-103 et seq.) (Legifrance).

AGA (Attributions Gratuites d’Actions)

• Legal basis: Code de commerce, art. L.225-197-1 et seq. (Legifrance).
• Limits: in principle 10% of capital (specific limits apply in certain situations). ANSA has clarified how the limit is calculated following a capital increase or successive issuances (ANSA — Legal Committee opinion).
• Timetable: minimum vesting period of 1 year and, except in specific cases, a combined vesting + holding period of at least 2 years (Service Public Pro).
• Beneficiary tax/social contributions: the acquisition benefit is treated as employment income (salaries and wages) and subject to social levies, while the subsequent disposal gain follows the securities regime (Service Public Pro).
• Employer cost: a specific employer contribution (30% in 2026, with adjustments for SMEs subject to conditions) based on value at vesting, plus ordinary social contributions where applicable (2026 Finance Act; Service Public Pro).

Quick comparison and selection criteria

• BSPCE — preferable if: you are an eligible young SAS/SA (< 15 years old) and primarily target employees/officers. Clear tax advantage, standardised process. Ideal at early/scale-up stages to recruit and align interests with exit value. Concise guide: Legalstart 2026 and legal framework CGI, art. 163 bis G.
• BSA — preferable if: you need flexibility (non-employee beneficiaries, advisers and partners), the company is ineligible for BSPCE, or you want a customised performance mechanism. Tax treatment is less favourable/less certain for employees; secure it through an independent valuation.
• AGA — preferable if: you want to retain people with more certain upside (free shares) and target key profiles. Employer costs are significant (dedicated contribution), with timetable/limit constraints. Practical references: Service Public Pro and Code de commerce, L.225-197-1 et seq..

A simple guide for 2026:

• Startup < 15 years old, organised as an SAS/SA, with a plan for employees/officers: prioritise BSPCE.
• Plan for advisers/suppliers/third parties, or a company ineligible for BSPCE: structured and valued BSA.
• Long-term retention packages for key executives, with a promise of shares: AGA, incorporating employer costs.

Operational method: ready-to-use checklist

Step 1 — Establish eligibility and governance

• Check the company’s legal form and age (BSPCE restricted to companies limited by shares < 15 years old) and liability to corporate income tax in France/EU/EEA (Legifrance; 2026 Finance Act).
• Have the EGM authorise the principle and limit, and delegate implementation to management (Code de commerce, L.225-129-2; L.228-92) (Legifrance).
• Adapt your articles/shareholders’ agreement to incorporate holders’ rights, bad-leaver clauses, liquidity and information. See our guide to drafting SAS articles suited to a startup and the key clauses of a shareholders’ agreement.

Step 2 — Design the plan and document value

• Draft plan rules (BSPCE/AGA) or a framework agreement (BSA): volume, vesting schedule, performance conditions, departures, liquidity events and exercise procedure (Service Public Pro).
• Obtain an independent valuation (DCF, comparables and option-based methods) to set the exercise price (BSPCE/BSA) and substantiate the absence of a benefit in kind. This step is decisive in avoiding social contribution/tax reclassification (AMF).
• Anticipate dilution and the fully diluted cap table. Read our measures to limit founder dilution.

Step 3 — Implement properly

• EGM notices and minutes, updated articles where appropriate, maintenance of the securities transfer register (and, for BSA, organisation of the body of holders).
• Delivery of grant letters and individual acceptances (BSPCE/AGA) or subscriptions (BSA), with clear pre-contractual information (risks, timetable and taxation).
• Related tax/social declarations (AGA) and tracking of vesting/holding periods. Practical references: Service Public Pro; guidance for entrepreneurs Bpifrance.

Common pitfalls and how to avoid them

• BSPCE outside the criteria (age > 15 years, not subject to corporate income tax in France/EU, ownership threshold not met): loss of preferential treatment. Check art. 163 bis G point by point (Legifrance) and 2026 developments (2026 Finance Act).
• “Overly generous” BSA without risk or valuation: risk of reclassification as salary with full social contributions. Secure the arrangement with a documented external valuation (AMF).
• AGA above the limits or with non-compliant timetables: risk of invalidity/tax risks. Refer to Code de commerce L.225-197-1 et seq. and ANSA opinions for technical cases (limits following capital increases) (Legifrance; ANSA).
• Overlooking corporate consistency: if you are still choosing between SAS or SARL for your startup, remember that BSPCE/BSA/AGA are reserved for companies limited by shares (SAS/SA/SCA).

Which instrument for which stage?

• Pre-seed/Seed (eligible SAS/SA): straightforward BSPCE, standard VC practice and clear tax treatment.
• Post-seed/Series A: a combination of BSPCE (employees) + targeted BSA (advisers/partners), with performance conditions.
• Scale-up/maturity: AGA to retain key executives + BSPCE for new recruits, while controlling budget costs. See also our SAS articles toolkit and coordination with the shareholders’ agreement.

Short FAQ

1) Can a subsidiary grant BSPCE?

Yes, if it meets the art. 163 bis G criteria (form, age, corporate income tax and ownership threshold) at its own level or through the expanded group scope allowed by recent Finance Acts. Refer to the clarifications in the 2026 Finance Act (De Pardieu — 2026 Finance Act).

2) How do you set the BSPCE/BSA exercise price?

On the basis of a documented independent valuation (recognised financial methods). A price that is too low increases social contribution/tax reclassification risk, particularly for BSA (AMF).

3) What is the employer cost of AGA?

A specific employer contribution (30% in 2026, SME adjustments) based on the value of the shares at vesting, potentially with additional contributions. See the current arrangements on Service Public Pro.
