What is an SCSp?

Introduced in 2013, the SCSp is Luxembourg's answer to the Anglo-Saxon limited partnership. It operates without direct regulatory supervision and offers maximum contractual freedom to design your own investment structure.

Key features at a glance

No legal personality - the SCSp does not constitute a legal entity distinct from that of its partners. This is familiar territory for investors used to common law limited partnerships.

Partner structure - at least one general partner with unlimited liability (typically a limited liability company to contain risk) and one or more limited partners whose exposure is capped at their capital commitment.

Maximum flexibility - the partnership agreement governs almost everything: profit sharing, governance, transfers, carried interest, waterfalls, and more. You design the structure you need.

Formation and registration

The SCSp may be established by a private agreement (sous seing privé), without the need for a notarial deed. The partnership agreement must be registered with the Luxembourg Trade and Companies Register (Registre de Commerce et des Sociétés) and must contain certain mandatory particulars, including the name of the partnership, its registered office, the identity of the partners, the purpose of the partnership, the duration (which may be limited or unlimited), and the contributions of each partner. The SCSp must include the designation "SCSp" or "société en commandite spéciale" in its name.

Management and governance

The general partner is responsible for the management and representation of the SCSp. Limited partners may not participate in the management of the partnership; any involvement in management activities may result in the loss of their limited liability status. However, limited partners may exercise certain supervisory, advisory, and consent rights without jeopardising their limited liability, provided these rights do not extend to day-to-day management.

Tax treatment

The SCSp is, in principle, treated as fiscally transparent for Luxembourg direct tax purposes, meaning that the partnership itself is not subject to corporate income tax or municipal business tax. Instead, income and gains are attributed to the partners and taxed at their level according to their respective tax status and residence. This transparency makes the SCSp particularly attractive for international investors seeking to avoid double taxation and to benefit from tax treaties applicable in their home jurisdictions.

The SCSp is also generally treated as a partnership (rather than a corporation) for the purposes of the tax laws of most other jurisdictions, though investors should confirm the treatment in their home jurisdiction on a case-by-case basis.

Structuring outside the scope of AIFMD

A key consideration when establishing an SCSp is whether the structure falls within the scope of the Alternative Investment Fund Managers Directive (AIFMD). If an SCSp qualifies as an alternative investment fund (AIF) under AIFMD, its manager (AIFM) must either be authorised by the CSSF or register under the partial exemption.

The core test - AIFMD applies to collective investment undertakings that (1) raise capital from multiple investors, (2) invest according to a defined investment policy, and (3) do so for the benefit of those investors. Structures that fail any limb of this test fall outside AIFMD entirely.

De Minimis thresholds - even if the SCSp qualifies as an AIF, its manager (GP) may escape full authorisation if assets under management stay below EUR 100 million (with leverage) or EUR 500 million (no leverage, no redemption rights for five years). Registration with the CSSF is still required, but not full authorisation.

Why legal advice is essential - the availability of these carve-outs is highly fact-specific. Get it wrong, and the consequences are serious: enforcement action, reputational damage, and potential liability for the general partner. Legal advice should be obtained at the outset to assess AIFMD scope, identify the appropriate carve-out, and ensure the partnership agreement supports the intended regulatory position. Ongoing monitoring is also critical: changes to investors, strategy, or AUM may alter the analysis.

Practical Considerations

While the SCSp offers considerable advantages, certain practical considerations should be borne in mind when establishing and operating the structure.

Investor profile - the SCSp may not be suitable for all investor profiles. Institutional investors subject to regulatory constraints may require the additional protections afforded by regulated fund structures. The choice between an SCSp and a regulated alternative should be made in light of the specific objectives, investor base, and regulatory considerations applicable to the proposed structure. Additionally, the private placement regime in each jurisdiction of the investor should be considered, as there may be additional considerations.

Anti-money laundering the applicable AML/CTF obligations for an SCSp and the GP will depend on the final structure falling within the definition of an AIF.

Beneficial ownership register - the SCSp is required to identify its beneficial owners and file this information with the Luxembourg Register of Beneficial Owners (Registre des Bénéficiaires Effectifs). Compliance with beneficial ownership reporting requirements is an ongoing obligation.

Conclusion

The Luxembourg SCSp has established itself as a highly flexible and tax-efficient vehicle for a wide range of investment and holding structures. Its contractual freedom, tax transparency, and absence of legal personality make it an attractive option for sponsors, fund managers, and investors seeking to establish bespoke arrangements in a well-regarded European jurisdiction. Given the complexity of the regulatory landscape and the significant consequences of inadvertent non-compliance, sponsors and investors should engage experienced legal counsel at the earliest opportunity.
