SICAV Luxembourg Création: A Legal Guide for Fund Structuring
The Luxembourg SICAV (Société d’Investissement à Capital Variable) remains the cornerstone of cross-border fund distribution, offering unparalleled flexibility for both UCITS and alternative investment strategies. With over €5 trillion in net assets under management housed in Luxembourg-domiciled funds, the jurisdiction’s legal certainty, investor-friendly tax environment, and robust regulatory framework make SICAV création a strategic choice for asset managers worldwide.
Whether you are launching a retail UCITS umbrella fund or a specialised alternative investment fund (AIF), understanding the incorporation process, CSSF approval requirements, and ongoing compliance obligations is essential. This guide, prepared by the corporate and investment fund lawyers at Lerusse Merckx & Partners, walks you through every step of SICAV Luxembourg création, from selecting the appropriate legal form to optimising your tax position and ensuring regulatory readiness.
What Is a SICAV? Legal Forms and Regulatory Regimes
A SICAV (société d’investissement à capital variable) is an investment company with variable capital whose sole object is the collective investment of its assets. Unlike ordinary commercial companies, a SICAV’s capital is always equal to its net asset value, allowing investors to enter and exit by subscribing or redeeming shares directly with the fund. This open-ended structure is the preferred vehicle for both UCITS and many alternative investment funds in Luxembourg.
The SICAV can be incorporated under the Law of 10 August 1915 on commercial companies as a public limited company (SA), a private limited company (Sàrl), a partnership limited by shares (SCA), or a cooperative company (SC). In practice, the SA form is overwhelmingly used for its familiarity with international investors and its compatibility with the UCITS framework. For alternative strategies, a SICAV may also be established as a specialised investment fund (SIF) or an investment company in risk capital (SICAR), each governed by distinct product laws.
UCITS vs. AIF: Choosing the Regulatory Regime
A SICAV can be authorised as a UCITS under the Law of 17 December 2010, benefiting from the European passport for retail distribution. UCITS SICAVs must comply with strict investment diversification rules, liquidity requirements, and investor protection standards. The minimum capital is €1.25 million, to be reached within six months of CSSF authorisation.
Alternatively, a SICAV may qualify as an alternative investment fund (AIF) under the Law of 12 July 2013 on alternative investment fund managers (AIFMD). AIF SICAVs enjoy greater investment freedom but require the appointment of a fully authorised AIFM unless they qualify for the registered AIFM regime (below €100 million AUM for unleveraged closed-ended funds). For managers seeking a lighter regulatory touch, the RAIF (Reserved Alternative Investment Fund) offers a non-CSSF-approved wrapper that must still appoint an authorised AIFM. Learn more about the RAIF Luxembourg: The Flexible Alternative Investment Fund Vehicle.
Umbrella Structures and Compartmentalisation
One of the most attractive features of a Luxembourg SICAV is the ability to create an umbrella fund with multiple compartments, each representing a distinct sub-fund with its own investment policy, currency, and fee structure. Under the 1915 Law, compartments are legally segregated: the assets and liabilities of one compartment are ring-fenced from others, and creditors of a compartment have recourse only to that compartment’s assets. This allows a single legal entity to host diverse strategies while protecting investors from cross-contamination.
The CSSF requires that the management regulations or articles of incorporation explicitly provide for the creation of compartments and define the rights of investors. Each compartment may issue different share classes, further enhancing flexibility for institutional and retail investors alike.
Key Steps in SICAV Luxembourg Création
The creation of a Luxembourg SICAV involves a structured process combining corporate incorporation and regulatory approval. The timeline from initial drafting to CSSF authorisation typically spans 8 to 12 weeks, depending on the complexity of the fund and the responsiveness of the initiator.
The process begins with the preparation of the constitutional documents: the articles of incorporation (for a self-managed SICAV) or the management regulations (for a SICAV managed by an external AIFM/UCITS management company). These documents must detail the investment policy, risk profile, valuation rules, and operational setup. Simultaneously, the depositary, central administration, and investment manager are selected and their agreements negotiated.
Incorporation and Notarial Deed
A SICAV taking the form of an SA must be incorporated by notarial deed before a Luxembourg notary. The deed includes the company’s name, registered office, corporate object, share capital, and governance structure. The minimum subscribed capital at incorporation is €30,000 for an SA, but for UCITS SICAVs, the capital must reach €1.25 million within six months of CSSF approval. The incorporation deed is filed with the Luxembourg Trade and Companies Register (RCS) and published in the Recueil Électronique des Sociétés et Associations (RESA).
For a SICAV managed by an external management company, the fund itself is often created as a common fund (FCP) or a SICAV without direct CSSF authorisation; the management company holds the license. However, a self-managed SICAV must obtain its own CSSF license, which involves a thorough review of the management body, central administration, and risk management framework.
CSSF Approval: Timeline and Requirements
The CSSF review process for a UCITS SICAV typically takes 2 to 3 months from the filing of a complete application. The application package includes the prospectus, articles of incorporation, KIID, depositary agreement, central administration agreement, and details of the board of directors and conducting officers. The CSSF verifies compliance with the UCITS Directive and Luxembourg product laws, focusing on investor protection, risk management, and operational substance.
For AIF SICAVs, the approval timeline depends on whether the fund is subject to CSSF product supervision (e.g., SIF, SICAR) or merely requires registration. A SIF SICAV must be authorised by the CSSF, a process that generally takes 2 to 3 months. In contrast, a RAIF is not subject to CSSF product approval, significantly accelerating the launch. For a deeper dive into AIFM requirements, see our AIFM Luxembourg Agrément CSSF: A Complete Guide.
Post-Approval Formalities
Once CSSF authorisation is granted, the SICAV must be registered with the RCS and the CSSF’s official list. The fund can then begin operations, including the issuance of shares. Ongoing obligations include the appointment of an approved statutory auditor (réviseur d’entreprises agréé), the production of annual and semi-annual reports, and compliance with CSSF circulars on risk management and governance.
Tax Regime for Luxembourg SICAVs
Luxembourg SICAVs benefit from a highly favourable tax framework designed to avoid double taxation and preserve investor returns. The key features are the subscription tax (taxe d’abonnement) and the exemption from corporate income tax, municipal business tax, and net wealth tax.
The subscription tax is an annual tax calculated on the net assets of the SICAV, payable quarterly. For UCITS SICAVs and most AIF SICAVs, the rate is 0.05% per annum. However, a reduced rate of 0.01% applies to compartments investing exclusively in money market instruments, deposits with credit institutions, or certain pension fund pooling vehicles. SICAVs investing in risk capital (SICAR) may be fully exempt from subscription tax if they meet specific criteria. For a detailed comparison, refer to our SICAR Luxembourg Investissement: A Comprehensive Legal and Tax Guide.
Exemption from Corporate Income Tax and Withholding Tax
A fully taxable SICAV is exempt from corporate income tax, municipal business tax, and net wealth tax. It is, however, subject to the subscription tax as described. Dividends distributed by the SICAV are not subject to Luxembourg withholding tax, regardless of the investor’s country of residence. Interest and capital gains are also free of withholding tax, making the SICAV a tax-transparent vehicle for international investors.
The SICAV is not entitled to the benefits of Luxembourg’s double tax treaties, as it is not considered a resident taxpayer for treaty purposes. However, investors may claim treaty benefits in their own jurisdictions. The SICAV itself may be subject to withholding taxes on foreign-source income, but Luxembourg’s extensive treaty network and the EU Parent-Subsidiary and Interest and Royalties Directives often mitigate this leakage.
VAT and Other Indirect Taxes
Management services provided to a SICAV are exempt from VAT under the EU VAT Directive, as interpreted by the European Court of Justice. This exemption covers investment management, administration, and depositary services. The SICAV itself is generally not required to register for VAT, except in specific cross-border situations. No stamp duty or capital duty is levied on the issuance of shares.
Structuring Options: Umbrella SICAV and Multiple Compartments
The umbrella SICAV is the most popular structure for asset managers seeking to offer multiple strategies under a single legal roof. Each compartment operates as a distinct sub-fund with its own investment objective, currency denomination, and fee schedule. The segregation of assets and liabilities between compartments is legally enforceable, providing robust investor protection.
Compartments can be created at incorporation or added later by amending the articles of incorporation. The CSSF must be notified of any new compartment, and the prospectus updated accordingly. This modularity allows managers to launch new products quickly without establishing a new legal entity, significantly reducing time-to-market and administrative costs.
Cross-Investment and Feeder Structures
A SICAV compartment may invest in other compartments of the same umbrella, subject to certain conditions to avoid conflicts of interest and ensure fair treatment of investors. The CSSF requires that cross-investment be disclosed in the prospectus and that no double charging of fees occurs. Feeder compartments can also be created to channel investments into a master fund, either within the same SICAV or externally.
For alternative strategies, the SICAV can be structured as a SIF or SICAR, offering even greater flexibility. The SICAR, for instance, is designed for risk capital investments and benefits from a full subscription tax exemption and a favourable tax regime for investors. Explore our SICAR Luxembourg Investissement guide for more details.
Regulatory Compliance and Ongoing Obligations
Once authorised, a Luxembourg SICAV is subject to continuous supervision by the CSSF. The fund must comply with the Law of 17 December 2010 (UCITS) or the AIFMD Law, as applicable, as well as CSSF circulars on topics such as risk management, liquidity stress testing, and outsourcing. The board of directors or management company bears ultimate responsibility for compliance.
The SICAV must appoint a Luxembourg-based depositary to safekeep its assets, monitor cash flows, and oversee the fund’s operations. The depositary plays a critical role in investor protection and is liable for the loss of financial instruments held in custody. The central administration (registrar and transfer agent, fund accounting) is typically delegated to a specialised service provider, ensuring accurate NAV calculation and shareholder record-keeping.
Annual Reporting and Audit
A SICAV must publish an audited annual report within four months of the financial year-end and a semi-annual report within two months of the period end. The annual report includes financial statements prepared in accordance with Luxembourg GAAP or IFRS, a management report, and the auditor’s opinion. The statutory auditor must be a réviseur d’entreprises agréé approved by the CSSF.
For UCITS SICAVs, a Key Investor Information Document (KIID) must be kept up to date and made available to investors. AIF SICAVs must comply with the AIFMD reporting obligations, including Annex IV transparency reports to the CSSF on a quarterly or annual basis, depending on AUM.
AIFM Requirements for Non-UCITS SICAVs
If the SICAV qualifies as an AIF, it must appoint a fully authorised AIFM unless it falls within the de minimis exemption (AUM below €100 million for unleveraged funds or €500 million for unleveraged closed-ended funds with no redemption rights for five years). The AIFM can be the SICAV itself (internally managed) or an external management company. The AIFM must comply with the AIFMD’s organisational, capital, and remuneration requirements.
