The Luxembourg SICAV-RAIF structure delivers unique advantages to institutional investors seeking efficient, open-ended fund platforms. By combining the variable capital company (SICAV) format with the Reserved Alternative Investment Fund (RAIF) regime, sponsors can deploy umbrella funds with operational flexibility and speed to market. The SICAV-RAIF offers multi-compartment structuring, access to all asset classes, and tax efficiency. Consequently, this hybrid structure has become a preferred choice for managers launching real estate, private equity, and multi-strategy funds targeting sophisticated investors.
What is a Luxembourg SICAV-RAIF?
A Luxembourg SICAV-RAIF is a variable capital investment company established under the Law of 23 July 2016 on reserved alternative investment funds (RAIF Law). The SICAV-RAIF regime allows managers to create open-ended funds without direct supervision by the CSSF. Instead, an authorised Alternative Investment Fund Manager (AIFM) oversees regulatory compliance. This approach accelerates fund launches and reduces the regulatory burden compared to traditional supervised funds.
Importantly, the SICAV-RAIF can invest in all asset classes, including private equity, real estate, infrastructure, debt, and hedge strategies. The regime restricts access to well-informed, professional, or institutional investors. As such, retail distribution is not possible. The SICAV-RAIF structure benefits from the umbrella fund concept, allowing the creation of multiple segregated compartments within one legal entity.
Article 1 of the RAIF Law defines the legal framework. The variable capital feature ensures that the fund capital automatically adjusts to subscriptions and redemptions at net asset value. In contrast, fixed capital funds require formal capital increases or reductions at the shareholders’ meeting or by notarial deed. This flexibility supports ongoing fundraising and efficient investor entry and exit. Notably, the SICAV-RAIF is not subject to the Law of 17 December 2010 on undertakings for collective investment (UCI Law), further streamlining compliance.

SICAV-RAIF vs SICAV-SIF: Which structure to choose?
The SICAV-RAIF and SICAV-SIF both enable variable capital, open-ended fund platforms for professional investors. However, significant differences exist in regulatory supervision, approval process, and operational flexibility.
Regulatory supervision and time-to-market
The CSSF directly supervises a SICAV-SIF under the Law of 13 February 2007 on specialised investment funds (SIF Law). Therefore, sponsors must submit the fund for approval before commencing activities. This process usually takes several months. In contrast, the SICAV-RAIF does not require CSSF approval. Instead, an AIFM manages the fund and ensures regulatory compliance. As a result, sponsors can launch a SICAV-RAIF within weeks, subject to AIFM onboarding and documentation finalisation.
Operational flexibility
Both structures permit umbrella fund platforms and multi-compartment structuring. However, the RAIF regime grants greater flexibility in eligible asset classes and investment strategies. For this reason, the SICAV-RAIF often attracts managers launching alternative strategies, such as real estate, private equity, infrastructure, and private debt. The SIF regime imposes stricter diversification rules and restricts certain asset types. Notably, both structures require investors to meet well-informed or professional criteria.
Distribution and investor access
Both SICAV-RAIF and SICAV-SIF qualify as alternative investment funds (AIFs) under the AIFMD. Consequently, they benefit from the AIFMD marketing passport for cross-border distribution to professional investors within the EEA. However, only the SIF can apply for UCITS status, which remains unavailable to RAIFs. In practice, managers seeking retail access or full UCITS status must select alternative structures.
Multi-compartment structuring with SICAV-RAIF
The SICAV-RAIF umbrella structure supports the creation of multiple segregated compartments, each with its own investment policy, asset pool, and investor base. Article 49 of the RAIF Law enshrines the segregation of assets and liabilities between compartments. As such, the liabilities of one compartment cannot affect the assets of another. This statutory ring-fencing provides comfort to institutional investors and family offices allocating capital to specific strategies.
Compartment flexibility and use cases
Managers can launch new compartments with distinct asset classes, fee structures, or investor eligibility requirements within one SICAV-RAIF platform. For example, a sponsor may operate real estate, private equity, and infrastructure strategies side by side. Moreover, the structure permits closed-ended or open-ended compartments, as well as different share classes and currencies. Notably, managers can launch new compartments efficiently without forming a new fund vehicle each time. This approach reduces set-up costs and streamlines ongoing administration.
Segregation of assets and liabilities
Article 50 of the RAIF Law ensures that creditors of one compartment cannot claim against the assets of another compartment. In turn, this statutory segregation supports investor protection and simplifies liability management. In practice, administrators, custodians, and auditors maintain separate records for each compartment. Therefore, each compartment has its own net asset value calculation, financial statements, and reporting requirements. Investors can select specific compartments based on their risk-return objectives without exposure to unrelated strategies.
SICAV-RAIF tax treatment and subscription tax
The Luxembourg SICAV-RAIF enjoys several tax advantages, making it attractive for international sponsors and investors. The fund itself does not pay corporate income tax, municipal business tax, or net wealth tax on its assets. Instead, it pays an annual subscription tax (“taxe d’abonnement”) of 0.01% on net assets, calculated quarterly. Notably, compartments dedicated to pension funds, microfinance, or certain sustainable investments may qualify for an exemption.
Investors benefit from the absence of Luxembourg withholding tax on distributions. In addition, the SICAV-RAIF may access double tax treaties in limited cases, depending on its legal form and substance. The variable capital company form (SICAV) typically does not qualify for treaty benefits. However, the partnership form (SCS or SCSp) can, in some circumstances, provide more favourable outcomes for tax-transparent structures.
Managers often use the SICAV-RAIF for real estate, private equity, and infrastructure strategies due to this tax neutrality. In particular, the structure avoids tax leakage at the fund level, maximising returns to investors. The choice of compartment structure, legal form, and location of underlying assets will affect the final tax position. Therefore, professional advice remains essential when designing a SICAV-RAIF platform.
Establishing a SICAV-RAIF platform in Luxembourg
Sponsors can set up a SICAV-RAIF by following a streamlined process. First, they determine the desired legal form—public limited company (S.A.), partnership limited by shares (SCA), or cooperative company (SCoopSA)—with SICAV status. They also appoint an authorised AIFM, which assumes responsibility for compliance with the AIFMD, including risk management, valuation, and investor disclosures. In turn, the SICAV-RAIF gains access to the AIFMD marketing passport for EEA distribution.
The fund’s constitutional documents (articles of association and offering memorandum) must detail the variable capital mechanism, compartment structure, investment strategies, and governance arrangements. Notably, the absence of CSSF approval means sponsors can launch the fund as soon as the notarial deed is executed and the AIFM is in place. This timing advantage is especially valuable for managers responding to investor demand or market opportunities.
In practice, the SICAV-RAIF must appoint a Luxembourg depositary, central administrator, and auditor. These service providers ensure operational robustness and regulatory compliance. The AIFM oversees risk management, valuation, and reporting. Furthermore, the board of directors retains overall responsibility for fund governance. Sponsors should consider local substance requirements to ensure ongoing compliance with Luxembourg company law and tax guidelines.
Managers wishing to establish a SICAV-RAIF for real estate, private equity, or multi-asset strategies can achieve significant structuring efficiencies. The combination of rapid launch, multi-compartment flexibility, and tax neutrality underpins the SICAV-RAIF’s popularity among institutional sponsors and family offices.
