Social Impact Companies in Luxembourg: serving sustainability with business

The law creating Social impact companies (SIS) was adopted in December 2016, after ongoing debates and discussions on the establishment of a specific legal status for businesses in the social and solidarity economy.

The SIS law was then reformed in 2021 in order to address some practical issues and simplify the process, but the spirit remains the same: a SIS is aimed at any individual or legal entity, whether acting alone or in partnership, that seeks to establish a business committed to activities grounded in the principles of the social and solidarity economy.


The SIS status is reserved to commercial companies (e.g. S.A, S.à.r.ls, Cooperatives) provided they comply with the principles of the social and solidarity economy.

The SIS is meant for both existing enterprises or organisations and project sponsors who wish to engage in an economic activity with a social or societal purpose.

The Ministry of Labour is in charge for accreditation as societal impact companies and has implemented an incubator that offers tailor-made support to carry out the procedures for setting up an SIS.

The SIS offers a number of benefits for the entity concerned, including a clearly defined legal framework, an appropriate tax regime, and access to national and European public procurement contracts.

Through the SIS approval, values such as solidarity, altruism, and non-profit orientation are supported, encouraged, and highlighted—not only as additional characteristics but as fundamental elements at the core of socially engaged companies.

This is why SISs are subject to strict obligations in terms of transparency and governance.

When drafting the articles of association for a SIS, it is essential to consider the following:

  • A precise definition of the pursued social objective (e.g. providing support to people in vulnerable situations, contributing to the preservation and development of social ties, the fight against exclusion and inequalities, the maintenance and strengthening of territorial cohesion, environmental protection, the development of cultural or creative activities, or the development of initial or continuing training activities).
  • A list of performance indicators that will enable the effective and reliable verification of the social objective’s achievement.
  • The necessity to respect the principle of limited profitability (The share capital must consist of at least 50% impact shares at all times.).
  • The requirement for autonomous management.

Holders of Impact shares cannot have the profit related thereto distributed to them, such profit being compulsorily reinvested in the realization of the corporate object of the SIS. 

Investors seeking for return on investment may however find an interest in investing in profit shares (whether voting or not), representing not more than 50% of the share capital. The SIS law does not prevent either the issue of profit shares outside of the share capital (parts bénéficiaires), which renders the investment structure flexible.

Depending on the amount of profit generated by the SIS, a statutory auditor or a supervisory auditor must be appointed in order among others to certify that the SIS law requirements are fulfilled.

In conclusion, Social Impact Companies are far from being philanthropic associations. They are real business oriented commercial companies, but with a social and sustainable object, designed to serve the solidarity economy. Cooperatives are a particularly adapted vehicle for achieving this goal.

Introduction Attracting and retaining international executive talent has long been a strategic priority for Luxembourg’s financial and corporate sectors. As part of the upcoming 2027 budgetary measures, the Luxembourg government has submitted Draft Law No. 8782 to Parliament, introducing a comprehensive overhaul of the tax framework governing stock options. Set to apply to options granted starting from tax year 2027, the legislative proposal replaces legacy administrative practices with a codified statutory structure, while introducing an exceptionally advantageous tax track for innovative start-ups. Pillar 1: The Favorable Regime for Innovative Young Enterprises (JEI) To reinforce Luxembourg's position as a dynamic hub for European venture capital and technology ventures, the bill introduces a specialized tax status under Articles 100bis and 104ter of the Luxembourg Income Tax Law (L.I.R.). For eligible Innovative Young Enterprises (Jeunes Entreprises Innovantes - JEI), the framework radically shifts the standard taxation timeline: Zero upfront taxation: The benefit-in-kind is valued at zero euros upon both grant and exercise. Deferred realization: Taxation applies solely at the disposal of the acquired equity. Favorable rate: Capital gains realized upon disposal are taxed as extraordinary income pursuant to Article 132 L.I.R., applying a reduced rate equal to one-quarter of the taxpayer's global tax bracket. Company Qualification Criteria To qualify under the JEI mechanism, an entity must satisfy cumulative statutory requirements: Incorporated for less than 10 years and registered with the Trade and Companies Register (RCS); Headcount under 150 full-time equivalent (FTE) employees, with a minimum operational staff of 2 FTEs; Annual net turnover or balance sheet total not exceeding 30 million euros; Demonstrated research and development commitment, representing at least 15 percent of total operating expenditure in at least one of the three preceding financial years, duly certified by an independent auditor or chartered accountant. Pillar 2: Codification of the General Regime (Article 104bis L.I.R.) For commercial enterprises that do not meet the JEI benchmarks, or where employers elect not to apply the start-up framework, the reform formalizes statutory rules under Article 104bis L.I.R., moving away from historical reliance on administrative circulars and creating absolute legal certainty. The codified general framework establishes two explicit operational tracks: Freely transferable options: Subject to taxation at the date of grant, evaluated on fair market value less any consideration paid by the employee. Non-transferable options: Taxed at the moment of exercise based on recognized financial methodologies, such as Black-Scholes valuation models. Mandatory holding relief: Where underlying shares are subject to contractually binding lock-up periods, employees benefit from a flat statutory discount of 5 percent per restricted year, capped at a maximum deduction of 20 percent, subject to statutory employer reporting. Transitional Rules: Impact on Existing Corporate Plans Draft Law No. 8782 establishes a clear cut-off criterion based strictly on the grant date: Legacy grants: All stock options granted prior to tax year 2027 remain governed by the legal and tax principles in force at the time of allocation. Future allocations: Any options granted from 2027 onwards will automatically fall under the amended statutory regime. This statutory rule applies irrespective of whether options are awarded under an existing corporate equity incentive plan or a newly drafted framework. Companies are not required to redraft existing overarching plan documentation, but subsequent allocations must be structured around the reformed statutory thresholds. Strategic Takeaways With parliamentary review currently underway, corporate employers, start-ups, and private equity-backed groups should conduct an early audit of their remuneration architecture. Reviewing plan terms and R&D expenditure metrics today will allow businesses to optimize incentive packaging ahead of the 2027 implementation date.
