What is a Luxembourg RAIF?
The Luxembourg Reserved Alternative Investment Fund (RAIF) is a flexible investment structure designed for institutional and well-informed investors. The RAIF regime, established by the Law of 23 July 2016, allows managers to launch a fund without direct authorisation or supervision by the Luxembourg financial regulator (CSSF). Instead, an authorised Alternative Investment Fund Manager (AIFM) oversees regulatory compliance and risk management. As a result, the RAIF combines regulatory oversight with fast time-to-market.
Managers use the RAIF for a wide range of investment strategies. For example, the RAIF structure suits real estate, private equity, private debt, and infrastructure investments. In addition, managers can use the RAIF to replicate the structuring flexibility of SIFs and SICARs while benefiting from a streamlined approval process. The RAIF also supports both open-ended and closed-ended fund models. As such, this makes it attractive to a broad spectrum of asset managers and institutional investors.
Luxembourg’s legislative framework grants the RAIF access to the European marketing passport under Directive 2011/61/EU (AIFMD) when managed by an EU-authorised AIFM. Accordingly, managers can market the RAIF to professional investors across the EU without separate registration in each jurisdiction. Meanwhile, the absence of direct CSSF approval significantly reduces the time and complexity of RAIF fund formation.

RAIF vs SIF: Key regulatory and structural differences
The Reserved Alternative Investment Fund and the Specialised Investment Fund (SIF) both target professional and institutional investors. However, their regulatory frameworks differ significantly. SIFs fall under the Law of 13 February 2007 and require direct authorisation and ongoing prudential supervision by the CSSF. In contrast, the RAIF Law of 23 July 2016 does not subject the RAIF itself to CSSF oversight. Instead, the appointed AIFM holds the regulatory responsibility. As a result, fund managers can launch a RAIF much faster than a SIF, often within weeks.
In addition, the SIF and RAIF share similar eligible asset and risk diversification requirements. Both vehicles permit investment in all asset classes, including real estate, private equity, debt, and infrastructure. However, only the RAIF benefits from the indirect regulatory approach, which delegates oversight to the AIFM. For this reason, managers seeking speed-to-market and operational efficiency often prefer the RAIF over the SIF.
Meanwhile, both structures support umbrella fund models with multiple compartments. Notably, the RAIF regime introduced greater flexibility in structuring, including the option of forming as an SCA, SCS, SCSp, SA, Sàrl, CoopSA, or SCoSA. In contrast, some legal forms are unavailable to the SIF. Accordingly, the RAIF has become the preferred vehicle for cross-border alternative investment strategies.
RAIF tax regime and subscription tax
The Luxembourg RAIF benefits from a favourable tax environment. In general, the tax regime depends on the RAIF’s investment policy. If the RAIF invests in risk capital, it may elect the SICAR tax regime and become fully tax-transparent for income and capital gains from eligible investments. Otherwise, most RAIFs fall under the SIF tax regime, where the fund does not pay corporate income tax, municipal business tax, or net wealth tax. Instead, the RAIF pays an annual subscription tax (taxe d’abonnement) of 0.01% on net asset value. The law exempts certain assets, such as investments in other Luxembourg funds or cash held at banks, from the subscription tax.
Specifically, managers of a RAIF real estate fund or a RAIF private equity fund can structure the vehicle to achieve tax neutrality at the fund level. In addition, the RAIF can access Luxembourg’s double tax treaty network if structured as a corporate entity. However, the SCSp form, often chosen for private equity or debt strategies, does not benefit from treaty access. For this reason, fund sponsors should weigh the choice of legal form and asset class at the structuring stage.
Meanwhile, the VAT regime applies in line with other Luxembourg fund vehicles. Management services provided to the RAIF enjoy VAT exemption under Article 44(1)(d) of the VAT Law. Furthermore, Luxembourg does not levy withholding tax on distributions by the RAIF to investors. As such, the RAIF structure offers significant tax efficiency for alternative investment strategies.
Tax considerations for RAIF debt funds
RAIF debt funds require particular attention to tax structuring. Luxembourg treats RAIFs as tax-transparent or opaque depending on their legal form. For example, the SCSp is fully tax-transparent and passes income and gains directly to investors. In contrast, a RAIF established as an SA or Sàrl is tax opaque but benefits from the subscription tax regime and potential treaty access. Therefore, managers must align the choice of legal form with the fund’s investment objectives and investor base.
Compartment structuring under the RAIF framework
Luxembourg law enables RAIFs to operate as umbrella funds with multiple compartments. Each compartment can pursue a distinct investment strategy, asset class, or investor base. Article 50 of the RAIF Law enshrines the principle of ring-fencing. As a result, the assets and liabilities of each compartment remain segregated from those of the others. Creditors of one compartment cannot claim against the assets of another.
Managers often use the RAIF’s compartment structure to consolidate several strategies within a single legal entity. For example, a sponsor might establish a RAIF with separate compartments for real estate, private equity, and debt investments. In turn, this approach streamlines governance, reduces operational duplication, and allows for cost sharing. Furthermore, managers can launch new compartments quickly without full fund re-approval. This flexibility makes the RAIF an attractive platform for institutional sponsors seeking scalable, multi-strategy solutions.
Meanwhile, each compartment can have tailored fee structures, distribution policies, and leverage profiles. Additionally, the RAIF can issue multiple share classes within each compartment to meet specific investor requirements. Notably, the legal segregation of compartments has proven effective in both market practice and Luxembourg court decisions.
RAIF formation: requirements, timeline, and AIFM appointment
Eligibility and investor profile
The RAIF regime restricts investment to professional investors, institutional clients, and well-informed individuals. The Law of 23 July 2016 defines well-informed investors as those investing at least EUR 125,000 or certified by a credit institution, investment firm, or management company as having appropriate expertise. Accordingly, the RAIF does not suit retail distribution.
Legal forms and structuring options
Sponsors can establish a RAIF using a wide range of legal forms. These include the SCA (partnership limited by shares), SCS (common limited partnership), SCSp (special limited partnership), SA (public limited company), Sàrl (private limited company), CoopSA (co-operative company), or SCoSA (co-operative company organised as a public limited company). Therefore, managers can select the legal form that aligns best with the target asset class and investor requirements. The SCSp structure is especially popular for private equity and debt funds due to its contractual flexibility and tax transparency.
Appointment of an authorised AIFM
The RAIF must appoint an authorised AIFM established in Luxembourg or another EU member state. The AIFM ensures compliance with the Alternative Investment Fund Managers Directive (AIFMD). The AIFM manages portfolio and risk management functions, oversees valuation processes, and ensures regulatory reporting. For this reason, the AIFM plays a central role in investor protection, AML/CFT compliance, and operational oversight. The AIFM requirement also enables the RAIF to benefit from the AIFMD marketing passport.
Timeline and operational steps
RAIF fund formation proceeds faster than traditional regulated funds. The absence of direct CSSF authorisation means the fund can launch as soon as sponsors complete the constitutional documents, appoint the AIFM, and secure the necessary service providers (depositary, administrator, auditor). Typically, sponsors can form a RAIF and accept investor commitments within 4–8 weeks. In contrast, the SIF or SICAR authorisation process can take several months. As a result, the RAIF structure offers a decisive advantage for sponsors seeking rapid market entry.
Ongoing compliance and reporting
Although the CSSF does not directly regulate the RAIF, the AIFM must comply with all AIFMD obligations. This includes risk management, leverage monitoring, investor disclosure, and regulatory reporting. In addition, the RAIF must prepare annual audited accounts and file them with the Luxembourg Trade and Companies Register. The depositary institution, typically a credit institution or professional depositary, safeguards the fund’s assets and monitors cash flows. These elements ensure the RAIF maintains a high standard of governance and investor protection in line with EU expectations.
