What is a Luxembourg RAIF?
The Luxembourg Reserved Alternative Investment Fund (RAIF) provides a flexible, institutional-grade fund structure for a wide range of alternative strategies. The RAIF regime, introduced by the Law of 23 July 2016, responds directly to investor demand for rapid market access and operational agility. A RAIF does not require direct approval or ongoing supervision from the Commission de Surveillance du Secteur Financier (CSSF). Instead, an authorised Alternative Investment Fund Manager (AIFM) manages the RAIF and ensures compliance with the Alternative Investment Fund Managers Directive (AIFMD).
Consequently, the RAIF appeals to fund managers seeking to launch real estate, private equity, debt, or infrastructure funds with minimal regulatory delay. The regime addresses the needs of institutional, professional, and well-informed investors. In practice, the AIFM assumes full responsibility for risk management, compliance, and portfolio management. This structure allows a RAIF to launch within weeks, bypassing lengthy CSSF application cycles.
Furthermore, the RAIF regime supports a broad array of legal forms, including the SCA, SCS, SCSp, SA, Sàrl, and cooperative company. Fund initiators can establish open-ended or closed-ended vehicles with variable or fixed capital. As such, the RAIF matches the flexibility and features of the SIF and SICAR, while offering greater speed to market.

RAIF vs SIF: Key regulatory and structural differences
Fund sponsors often compare the RAIF and the Specialised Investment Fund (SIF) when selecting a structure. Both regimes target well-informed investors, permit a broad investment policy, and support multiple asset classes. However, significant structural and regulatory distinctions exist.
Regulatory supervision and fund launch
The CSSF authorises and supervises SIFs directly. In contrast, the CSSF does not oversee RAIFs directly. Instead, the AIFM ensures regulatory compliance, reporting, and risk management for the RAIF. As a result, fund managers can launch a RAIF much faster than a SIF.
Additionally, the SIF requires pre-approval from the CSSF before marketing or investment activities begin. The RAIF regime removes this bottleneck. Managers may launch the RAIF immediately after notarial incorporation and AIFM appointment, subject to legal documentation and investor disclosure.
Eligible investors and risk diversification
Both RAIFs and SIFs restrict access to institutional, professional, and well-informed investors. The RAIF must maintain risk-spreading, mirroring the SIF’s diversification rules. In practice, the AIFM enforces this policy through the fund’s investment guidelines.
Legal forms and structuring
The RAIF and SIF allow the same range of legal forms, including the SCSp, SCS, SCA, SA, and Sàrl. Both vehicles offer umbrella structures with segregated compartments. However, the RAIF provides greater flexibility for managers who value speed and wish to avoid direct CSSF oversight. For this reason, most new Luxembourg alternative funds now choose the RAIF over the SIF.
RAIF tax regime and subscription tax
The RAIF benefits from a favourable Luxembourg tax regime. Typically, a RAIF qualifies for exemption from corporate income tax, municipal business tax, and net wealth tax. Instead, the fund pays an annual subscription tax (taxe d’abonnement) of 0.01% on net asset value. The authorities calculate this tax quarterly on the fund’s net assets.
Notably, the subscription tax does not apply to assets invested in other Luxembourg investment funds, nor to certain money market or pension fund assets. In addition, the RAIF may access Luxembourg’s network of double tax treaties if structured as a corporate entity.
Luxembourg does not withhold tax on distributions to investors. This feature appeals to international investors and cross-border structures. However, the RAIF must comply with anti-money laundering (AML) and tax transparency rules under the Law of 12 November 2004 and OECD Common Reporting Standard (CRS) obligations.
Special tax regime for risk capital RAIFs
When a RAIF invests exclusively in risk capital, it may opt for a tax regime similar to the SICAR. In this case, the fund becomes subject to standard Luxembourg corporate tax but enjoys exemption for qualifying income and gains from risk capital investments. Managers often select this regime for private equity or venture capital strategies targeting capital gains rather than income returns.
Fund sponsors should analyse the investment policy, asset location, and investor base to optimise tax efficiency. Careful structuring can enhance treaty access and minimise tax leakage for the RAIF and its investors.
Compartment structuring under the RAIF framework
The RAIF regime supports umbrella funds with multiple segregated compartments. Article 50 of the Law of 23 July 2016 enshrines the legal ring-fencing of assets and liabilities between compartments. As a result, a creditor of one compartment cannot claim against another compartment’s assets.
Fund managers often use compartment structuring to launch multiple strategies, asset pools, or investor share classes under a single legal entity. For example, a RAIF may hold separate real estate, private equity, and debt compartments. Each compartment maintains distinct portfolios, fee schedules, and distribution policies. Accordingly, the board and AIFM must clearly allocate assets, liabilities, and income by compartment.
Practical uses of compartments
Managers leverage compartments for cost efficiency, rapid product launches, and operational flexibility. Each compartment may appoint different external service providers, such as depositaries, administrators, or investment advisers. Moreover, the RAIF can add new compartments through board resolution and notarial update, allowing swift market response.
In turn, investors may subscribe to specific compartments that fit their risk appetite or asset preferences. Luxembourg law provides robust protection for compartment segregation, reducing cross-contamination risk and enhancing investor confidence.
RAIF formation: requirements, timeline, and AIFM appointment
Setting up a Luxembourg RAIF involves a straightforward process. Fund initiators select the legal form, draft the constitutive documents, and appoint an authorised AIFM. Only a fully authorised AIFM can manage a RAIF. The AIFM may be based in Luxembourg, another EU member state, or in certain non-EU countries if equivalence applies.
The AIFM must ensure portfolio and risk management and oversee compliance with AIFMD requirements. The AIFM also takes responsibility for valuation, reporting, and investor disclosures. Meanwhile, the RAIF must appoint a Luxembourg depositary to safeguard assets and monitor cash flows. The choice of depositary depends on the fund’s legal form. For example, a credit institution or investment firm must act as depositary for SCA, SA, or Sàrl RAIFs, while a professional depositary can serve partnerships (SCS/SCSp).

Typically, the RAIF formation process takes two to four weeks, depending on documentation and service provider readiness. There is no CSSF approval or review period, significantly reducing time-to-market. The RAIF must register with the RCS and comply with ongoing regulatory and tax reporting requirements.
Managers must ensure that marketing and distribution comply with AIFMD passporting rules where the AIFM is EU-based. The RAIF must provide eligible investors with a detailed information memorandum outlining strategy, risks, fees, and governance. In practice, the AIFM, depositary, and administrator support the fund’s day-to-day compliance and operational functions.
