RAIF Law Luxembourg: The Complete Legal and Tax Guide 2026
The Reserved Alternative Investment Fund (RAIF) has rapidly become one of Luxembourg’s most popular investment vehicles since its introduction by the law of 23 July 2016. Designed to offer the flexibility of an unregulated fund while benefiting from the robust Luxembourg legal and tax environment, the RAIF law Luxembourg framework allows fund managers to launch alternative investment funds quickly without prior approval from the Commission de Surveillance du Secteur Financier (CSSF). This unique combination of speed, efficiency, and the renowned Luxembourg brand has attracted a wide range of asset managers, from private equity and real estate to venture capital and infrastructure.
At Lerusse Merckx & Partners, we provide comprehensive legal and tax advice on structuring RAIFs under Luxembourg law. Whether you are considering launching a new fund or converting an existing structure, understanding the RAIF law lux framework is essential to optimizing your fund’s setup. In this guide, we explore the key legal provisions, tax advantages, regulatory requirements, and practical steps for establishing a RAIF in Luxembourg, with concrete data and expert insights to help you make informed decisions.
What is the RAIF Law in Luxembourg?
The RAIF law Luxembourg, formally the Law of 23 July 2016 on reserved alternative investment funds, created a new category of investment vehicle that is not subject to CSSF product approval. Instead, a RAIF must be managed by an authorized alternative investment fund manager (AIFM) established in Luxembourg or another EU/EEA member state. This indirect supervision via the AIFM allows the RAIF to be set up within a matter of weeks, compared to several months for a fully regulated fund such as a SIF or SICAR. As of 2024, over 2,500 RAIFs have been launched, representing more than €500 billion in net assets, according to the CSSF.
The legal framework is built on the existing Luxembourg fund toolbox, incorporating elements from the SIF and SICAR regimes. A RAIF can be structured as a common contractual fund (FCP), an investment company with variable capital (SICAV), or a fixed capital company (SICAF). It can also take the form of a SICAR if it invests in risk capital, or a SIF if it is intended for well-informed investors. This versatility makes the RAIF law lux framework highly attractive for a broad spectrum of investment strategies. For a deeper dive into the definition and scope, see our RAIF Luxembourg Definition: Complete Legal & Tax Guide.
Legal Basis and Key Provisions
The RAIF law is codified in the Luxembourg law of 23 July 2016, which amended the existing legislation on specialized investment funds and risk capital investment companies. The key provision is that a RAIF is not required to obtain prior authorization from the CSSF for its establishment, but it must be managed by a fully authorized AIFM. This AIFM is responsible for compliance with the AIFMD, including reporting, risk management, and investor disclosure. The RAIF itself is registered with the Luxembourg trade and companies register (RCS) and must comply with certain ongoing obligations, such as annual reporting and anti-money laundering rules.
The law also sets out the eligible investors: RAIFs are reserved for well-informed investors, defined as institutional investors, professional investors, or any other investor who meets the criteria of a well-informed investor under the SIF law. This means that RAIFs cannot be marketed to retail investors, preserving their exclusive character. The minimum investment per investor is typically €125,000, unless the RAIF takes the form of a SICAR, in which case the minimum capital requirement for the fund itself is €1,000,000, to be reached within 12 months.
Key Features of the RAIF Legal Framework
The RAIF law Luxembourg offers a unique blend of flexibility and investor protection. One of its standout features is the absence of CSSF product approval, which significantly reduces time-to-market. A RAIF can be established in as little as 2-4 weeks, provided the AIFM is already authorized. This speed is a critical competitive advantage in the fast-moving alternative investment space. Additionally, the RAIF can be set up as an umbrella fund with multiple sub-funds, each with its own investment policy and segregated liability, allowing for efficient portfolio management.
Another important feature is the wide range of eligible assets. A RAIF can invest in virtually any type of asset, including private equity, real estate, debt instruments, hedge fund strategies, and infrastructure. There are no investment restrictions, provided the risk profile is adequately disclosed to investors. The RAIF must also appoint a Luxembourg-based depositary, an approved statutory auditor, and a central administration, ensuring a high level of oversight.

Investor Eligibility and Marketing Rules
Under the RAIF law lux, the fund is strictly reserved for well-informed investors. This category includes institutional investors, professional investors within the meaning of MiFID, and any other investor who meets at least two of the following criteria: (i) a minimum investment of €125,000, (ii) sufficient knowledge and experience in financial matters, and (iii) a net worth of at least €1,250,000. These criteria ensure that investors are capable of understanding the risks associated with unregulated funds.
Marketing of RAIFs is governed by the AIFMD. The AIFM can market the RAIF to professional investors across the EU under the AIFMD passport, once the necessary notifications are made. For non-EU marketing, the RAIF can rely on national private placement regimes. It is important to note that the RAIF itself does not have a passport; the passport is attached to the AIFM. This structure allows for efficient cross-border distribution while maintaining the fund’s unregulated status.
RAIF vs Other Luxembourg Investment Vehicles
Luxembourg offers a comprehensive range of investment vehicles, each with its own regulatory profile. The RAIF law Luxembourg positions the RAIF as a hybrid between the fully regulated SIF and SICAR and the completely unregulated SOPARFI. Unlike a SIF, which requires CSSF approval and ongoing supervision, a RAIF benefits from indirect supervision through its AIFM. This makes it faster to launch and less costly to maintain, while still providing a high degree of investor confidence thanks to the AIFM’s oversight.
Compared to a SICAR, which is designed for risk capital investments and offers a specific tax regime, a RAIF can adopt the SICAR form and benefit from the same tax treatment, but without the need for CSSF approval. This is particularly advantageous for private equity and venture capital funds. For a detailed analysis of the SICAR-RAIF combination, see our Luxembourg SICAR RAIF: Complete Legal and Tax Guide. The RAIF also differs from a SOPARFI, which is a standard commercial company used as a holding vehicle and not subject to fund regulation. The choice depends on the investment strategy, investor base, and tax considerations.
RAIF vs SIF: Regulatory and Tax Comparison
The SIF (Specialized Investment Fund) is a regulated vehicle under the SIF law of 2007, requiring prior CSSF approval and ongoing prudential supervision. The SIF is also reserved for well-informed investors but offers a higher degree of regulatory oversight, which may be preferred by certain institutional investors. In terms of tax, both the SIF and the RAIF are subject to an annual subscription tax of 0.01% on net assets, with exemptions for certain asset classes such as cash, pension fund investments, and other funds. However, the RAIF can also be structured as a tax-transparent entity, offering additional flexibility.
The key difference lies in the setup time and cost. A SIF can take 3-6 months to obtain CSSF approval, while a RAIF can be operational in weeks. The ongoing regulatory burden is also lighter for a RAIF, as it is not directly supervised by the CSSF. This makes the RAIF particularly attractive for first-time fund managers and those seeking a quick market entry.

Tax Regime for RAIFs under Luxembourg Law
The tax treatment of a RAIF under Luxembourg law is one of its most compelling features. Generally, a RAIF is subject to corporate income tax, municipal business tax, and net wealth tax, but the effective tax burden can be minimized through structuring. If the RAIF takes the form of a SICAR, it benefits from a specific tax regime: it is fully subject to corporate taxes, but income from transferable securities is exempt, and dividends are not subject to withholding tax under certain conditions. This makes the SICAR-RAIF structure highly tax-efficient for private equity investments.
Alternatively, a RAIF can be structured as a tax-transparent entity, such as an FCP, which is not subject to corporate income tax at the fund level. Instead, income flows through to investors, who are taxed according to their own circumstances. This is particularly attractive for international investors seeking to avoid double taxation. The annual subscription tax of 0.01% applies to most RAIFs, but exemptions are available for certain asset classes, such as money market instruments, deposits, and investments in other Luxembourg funds that have already paid the tax. For a detailed guide on the SICAR tax regime, see our SICAR Tax Regime Luxembourg: Complete 2026 Guide.
Subscription Tax and VAT Considerations
The subscription tax (taxe d’abonnement) is calculated quarterly on the net assets of the RAIF and is payable at a rate of 0.01% per annum. For RAIFs that are SICARs, the rate is also 0.01%, but only on the portion of net assets not invested in risk capital. Certain exemptions apply, such as for assets held in cash awaiting investment, investments in other Luxembourg funds that have already paid the tax, and pension fund assets. This can significantly reduce the effective tax rate.
Regarding VAT, management services provided to a RAIF are generally exempt from VAT in Luxembourg, in line with the EU VAT Directive. This exemption applies to the AIFM’s management fees, as well as to advisory and administrative services. However, it is important to structure the service agreements correctly to ensure the exemption applies. Our team at Lerusse Merckx & Partners can assist with optimizing the tax structure of your RAIF to maximize efficiency.
Setting Up a RAIF: Legal and Regulatory Steps
The process of establishing a RAIF under Luxembourg law is streamlined but requires careful planning. The first step is to select the appropriate legal form: FCP, SICAV, or SICAF, and whether to adopt the SICAR or SIF regime. Next, the fund must appoint a fully authorized AIFM, which can be an existing Luxembourg AIFM or a new one. The AIFM will be responsible for portfolio management, risk management, and regulatory compliance. The RAIF must also appoint a Luxembourg-based depositary, an approved statutory auditor (réviseur d’entreprises agréé), and a central administration.
The incorporation documents, including the management regulations (for an FCP) or articles of incorporation (for a SICAV/SICAF), must be drafted and notarized. The RAIF is then registered with the Luxembourg Trade and Companies Register (RCS). No CSSF approval is required, but the AIFM must notify the CSSF of the RAIF’s establishment within one month. The entire process can be completed in 2-4 weeks, assuming the AIFM is already authorized. For a step-by-step guide on fund formation, see our Luxembourg Company Formation & Registration: Step-by-Step Legal Guide 2026.
Ongoing Obligations and Reporting
Once established, a RAIF must comply with ongoing obligations, including annual audited financial statements, semi-annual reports, and AIFMD reporting by the AIFM. The RAIF is also subject to anti-money laundering (AML) and know-your-customer (KYC) requirements, as well as the Common Reporting Standard (CRS) and FATCA. While the RAIF itself is not directly supervised by the CSSF, the AIFM’s oversight ensures a high level of compliance.
The RAIF must also adhere to the investment restrictions and risk diversification rules set out in its offering documents. Although there are no statutory investment limits, the AIFM must ensure that the fund’s risk profile is consistent with its stated strategy and that investors are adequately informed. Regular board meetings and investor reporting are essential to maintain good governance. Lerusse Merckx & Partners provides ongoing legal support to ensure your RAIF remains compliant with all Luxembourg and EU regulations.
Why Choose a RAIF? Advantages for Fund Managers and Investors
The RAIF law Luxembourg offers a compelling value proposition for both fund managers and investors. For managers, the primary advantages are speed to market, lower setup and operating costs, and the ability to leverage the Luxembourg brand without the burden of direct CSSF supervision. The RAIF can be used for a wide range of strategies, from traditional private equity to niche asset classes like crypto assets or litigation finance. The umbrella structure allows for efficient scaling, and the tax flexibility enables optimization for different investor profiles.
For investors, the RAIF provides access to a well-regulated environment through the AIFM, combined with the tax benefits of a Luxembourg vehicle. The requirement for a depositary and an approved auditor offers a high level of asset protection. Moreover, the RAIF’s eligibility for the AIFMD passport facilitates cross-border marketing, giving investors access to a broader range of opportunities. As of 2024, the RAIF has become the vehicle of choice for over 60% of new alternative fund launches in Luxembourg, a testament to its success.
Case Study: Private Equity RAIF in Practice
Consider a mid-sized private equity firm looking to launch its first institutional fund. By choosing a RAIF in the form of a SICAR, the firm can benefit from the SICAR tax regime, which exempts income from securities, while avoiding the lengthy CSSF approval process. The fund can be set up within three weeks, with an authorized AIFM providing the necessary regulatory umbrella. The subscription tax is minimized by investing in portfolio companies quickly, and the fund can market to professional investors across the EU under the AIFMD passport. This structure has been used by numerous firms to raise capital efficiently and focus on deal-making rather than regulatory hurdles.
Another example is a real estate fund investing in commercial properties across Europe. A RAIF structured as an FCP can achieve tax transparency, allowing non-resident investors to avoid Luxembourg corporate tax. The fund can hold properties through Luxembourg SOPARFI subsidiaries, benefiting from double tax treaties and the participation exemption. This layered structure is a classic Luxembourg approach, combining the RAIF’s flexibility with the SOPARFI’s tax efficiency. For more on SOPARFI, see our SOPARFI Luxembourg: The Ultimate Holding Company Guide 2026.
Questions fréquentes (FAQ)
What is the minimum capital requirement for a RAIF under Luxembourg law?
The minimum capital for a RAIF depends on its legal form. For a RAIF structured as a SICAR, the minimum capital is €1,000,000, which must be reached within 12 months of incorporation. For other forms, such as a SIF-like RAIF, the minimum capital is typically €1,250,000, but this can be lower if the fund is structured as an FCP. There is no statutory minimum for an FCP, but the offering documents usually set a minimum fund size to ensure economic viability.
Is a RAIF regulated by the CSSF?
No, a RAIF is not directly regulated or supervised by the CSSF. It is an unregulated vehicle that must be managed by an authorized AIFM, which is supervised by the CSSF. This indirect regulation ensures investor protection while allowing for a faster and more flexible setup process.
