The Luxembourg SICAV-RAIF merges the advantages of an open-ended variable capital investment company with the regulatory flexibility of the Reserved Alternative Investment Fund (RAIF) regime. As a result, institutional investors and fund managers can build scalable, efficient fund platforms. We examine key features, structuring options, and regulatory considerations for SICAV-RAIFs, including tax treatment and practical formation steps.
What is a Luxembourg SICAV-RAIF?
The SICAV-RAIF structure combines two proven Luxembourg fund concepts. A SICAV (Société d’Investissement à Capital Variable) is an open-ended investment company. Its capital always equals its net asset value, so it can issue and redeem shares flexibly. The RAIF (Reserved Alternative Investment Fund), governed by the Law of 23 July 2016, is a fund regime reserved for professional, institutional, or well-informed investors. The RAIF does not require direct authorisation or supervision by the CSSF. Instead, an authorised AIFM manages the fund and ensures regulatory compliance.
By structuring a RAIF as a SICAV, sponsors can offer investors an open-ended vehicle, with variable capital and compartmentalisation. The fund can invest in any asset class permitted under the AIFMD, including real estate, private equity, infrastructure, debt, and hedge strategies. Furthermore, the SICAV-RAIF can take several legal forms. The most common is the public limited company (S.A.), but other company types are possible.
Notably, Luxembourg’s flexible legal framework allows the SICAV-RAIF to combine rapid time-to-market with strong investor protections. The AIFM ensures risk management, valuation, and regulatory reporting. In practice, the SICAV-RAIF has become a preferred structure for managers launching multi-compartment umbrella funds targeting institutional investors.

SICAV-RAIF vs SICAV-SIF: Which structure to choose?
Both SICAV-RAIF and SICAV-SIF (Specialised Investment Fund) serve institutional and professional investors. However, they differ in regulatory approach, time-to-market, and ongoing supervision. The SICAV-SIF, governed by the Law of 13 February 2007, requires prior approval and ongoing supervision by the CSSF. Consequently, setting up a SICAV-SIF takes longer and involves more regulatory steps. In contrast, the SICAV-RAIF can launch immediately after notarial incorporation, provided an authorised AIFM is in place. No direct CSSF authorisation is needed for the fund itself.
For managers seeking speed and lower setup costs, the SICAV-RAIF offers a practical advantage. The AIFM must comply with AIFMD requirements, including risk management and investor reporting. In turn, the RAIF regime delivers equivalent regulatory assurance through the AIFM, without duplicating CSSF oversight. Furthermore, both structures permit umbrella funds with segregated compartments. Each compartment can have its own investment strategy, asset pool, and investor base. However, the SICAV-RAIF allows more flexibility in adapting to market opportunities.
For example, when launching a SICAV-RAIF real estate or private equity fund, managers can quickly add new compartments as investor demand evolves. By contrast, the SICAV-SIF process is slower and less adaptable. Therefore, many sponsors now opt for the SICAV-RAIF as the default Luxembourg structure for institutional alternative funds.
Multi-compartment structuring with SICAV-RAIF
The SICAV-RAIF regime supports efficient multi-compartment umbrella funds. Each compartment acts as a ring-fenced sub-fund, with legally segregated assets and liabilities. Article 50 of the Law of 23 July 2016 enshrines this ring-fencing. Creditors of one compartment cannot claim against the assets of another. This structure enables managers to launch multiple strategies, asset classes, or investor pools within one legal entity.
For example, a SICAV-RAIF umbrella can offer separate compartments for real estate, private equity, infrastructure, and debt. Each compartment can set its own investment objective, fee structure, and risk profile. Additionally, managers can launch new compartments rapidly, without incorporating a new legal entity or seeking CSSF approval. In practice, this approach reduces operational costs, streamlines legal documentation, and accelerates time-to-market.
Furthermore, the SICAV-RAIF supports both open-ended and closed-ended compartments. This flexibility allows sponsors to match liquidity terms to the underlying asset class. For instance, private equity compartments can restrict redemptions, while hedge fund compartments can offer periodic liquidity.
Custodian banks, central administrators, and AIFMs often provide umbrella-wide services, but each compartment must maintain separate accounting. Investors benefit from clear segregation and transparent reporting per compartment. As a result, institutional allocators can access a tailored investment offering while maintaining risk isolation between strategies.
SICAV-RAIF tax treatment and subscription tax
Luxembourg grants the SICAV-RAIF favourable tax treatment. The SICAV-RAIF qualifies as a tax opaque entity, but does not pay corporate income tax or municipal business tax on its investment income. Instead, it pays an annual subscription tax (taxe d’abonnement) of 0.01% on net assets, calculated quarterly. This subscription tax applies at the fund level, not to the investors. Certain compartments, such as those investing in money market instruments or benefiting from special exemptions, may qualify for a reduced or zero rate.
Furthermore, the SICAV-RAIF benefits from Luxembourg’s extensive network of double tax treaties, provided it takes the form of a public limited company (S.A.). However, the RAIF does not always enjoy treaty access if structured as a partnership. In addition, the SICAV-RAIF is exempt from net wealth tax and capital duty. Distributions to investors do not attract Luxembourg withholding tax.
For managers structuring SICAV-RAIF real estate or private equity funds, careful attention to tax residency, substance, and treaty eligibility is essential. The choice of compartment structure can also influence tax outcomes. Therefore, sponsors should coordinate with Luxembourg tax advisors to optimise the fund’s tax position and investor returns.
Establishing a SICAV-RAIF platform in Luxembourg
Key formation steps
Establishing a SICAV-RAIF involves several steps. Sponsors must first select a legal form (typically S.A.), define the investment policy, and draft the constitutive documents. The notary incorporates the SICAV-RAIF, and the fund can begin operations immediately provided an authorised AIFM has been appointed. The fund must appoint a depositary, central administrator, and auditor. The AIFM assumes responsibility for portfolio management, risk management, and AIFMD compliance. Investors must meet the RAIF eligibility criteria: institutional, professional, or well-informed status.
Minimum capital for a SICAV-RAIF is EUR 1,250,000, to be reached within 12 months. Initial capital can be lower at launch, but the fund must reach the threshold within the first year. The central administration must be located in Luxembourg, and the SICAV-RAIF must maintain a Luxembourg registered office.
Operational considerations
Managers launching a SICAV-RAIF should consider the following:
- Appointing a reputable AIFM with experience in the relevant asset class
- Luxembourg SCSp: Special Limited Partnership Structuring and Tax Transparency
- Luxembourg RAIF: Reserved Alternative Investment Fund Essentials for 2024
- Luxembourg Depositary Bank: Depositary Services, Duties and Selection Criteria
Additionally, sponsors benefit from Luxembourg’s strong legal certainty, business-friendly environment, and efficient service provider ecosystem. The SICAV-RAIF regime accommodates both institutional club deals and larger fund platforms. Managers can structure carried interest, co-investment opportunities, and bespoke fee arrangements within individual compartments. For this reason, the SICAV-RAIF remains highly attractive for real estate, private equity, infrastructure, and multi-strategy funds seeking a Luxembourg base.
