CSSF Fund Submission Information

Overview

The Commission de Surveillance du Secteur Financier (CSSF) is Luxembourgs financial regulator. All investment funds that wish to be domiciled or marketed in Luxembourg must obtain CSSF approval before they can be launched. This guide summarises the main steps, documentation and bestpractice tips for a successful fund submission.

Eligibility Criteria

Before preparing a submission, verify that your fund meets the following basic conditions:

• Legal structure is recognised under Luxembourg law (e.g., SICAV, SICAF, SIF, RAIF, UCITS, etc.).
• At least one authorised alternative investment fund manager (AIFM) or UCITS management company is appointed.
• Minimum capital requirements are satisfied (e.g., 125,000 for a SIF, 300,000 for a SICAV).
• All shareholders, directors and service providers are identified and meet fitandproper standards.

Required Documents

The CSSF expects a comprehensive dossier. The most frequently requested items are listed below.

All documents must be submitted in French or English. If a document is originally in another language, a certified translation is required.

Submission Process

1. Preparation Assemble the dossier, verify that each file complies with the CSSFs format guidelines (PDF/A1b, 10MB maximum per file).
2. Electronic Upload Use the CSSFs esubmission portal (eFonds) to upload the complete package. A unique reference number is generated automatically.
3. Acknowledgement The CSSF sends a receipt confirming that the submission has been received and is under review.
4. Prescreening The regulator checks for completeness. Missing items are communicated within 5 business days.
5. Formal Review Subjectmatter experts evaluate the funds compliance with the Law of 17 December 2010 (SIF law), the Law of 12 July 2013 (RAIF law), or the UCITS directives, as applicable.
6. Clarifications If the CSSF needs additional information, it issues a request for clarification. Responses must be provided within the deadline stated (normally 1015 days).
7. Decision The CSSF issues either an approval letter (with registration number) or a refusal, detailing the reasons for rejection.
8. Publication Approved funds are listed in the CSSFs public register and may commence marketing.

Typical Timeline

While each case varies, the following schedule provides a realistic expectation for a standard SIF or SICAV submission:

• Day 010: Preparation of documents.
• Day 1115: Upload to eFonds and receipt of acknowledgement.
• Day 1630: Completeness check by the CSSF.
• Day 3170: Formal review and possible clarification rounds.
• Day 7180: Final decision and registration.

Overall, a wellprepared dossier can be approved within 23 months. Delays usually stem from missing documentation or substantive regulatory questions.

Common Issues & How to Avoid Them

• Incomplete FitandProper Declarations Ensure every individual listed in the Key Function table has a signed declaration and supporting CV.
• Nonstandard File Formats Use PDF/A1b for all PDFs and avoid embedded fonts that are not embedded correctly.
• Missing AML Policies Include a dedicated AML chapter in the compliance manual, even if the fund is a private placement.
• Capital Proof Not Certified Obtain a bankissued letter on official letterhead confirming the capital amount.
• Language Errors Have a nativespeaker reviewer proofread all English/French documents before upload.

Frequently Asked Questions

What is the difference between a SIF and a RAIF?

A SIF (Specialised Investment Fund) requires CSSF approval before launch, whereas a RAIF (Reserved Alternative Investment Fund) is exempt from prior approval. The RAIF still needs an authorised AIFM, but the regulator only checks the managers compliance after the fund is operational.

Can the same dossier be used for multiple fund structures?

Only the sections that are identical (e.g., managers policies, AML procedures) can be reused. Each funds prospectus, statutes and riskmanagement annexes must be specific to that structure.

Do I need a Luxembourg tax identification number (TIN) for the fund?

Yes. The fund must obtain a Luxembourg tax identification number (TIN) from the Administration des Contributions Directes before the CSSF can issue the registration certificate.

How long does the CSSF keep the registration documents?

All registration files are retained for at least ten years in the CSSFs archive, as required by Luxembourg law.

Is an external audit mandatory before registration?

For SIFs and SICAVs, the CSSF requires an initial audit report covering the funds accounting setup and internal controls. The audit must be performed by a Luxembourgregistered audit firm.

What if the CSSU (Commission de Surveillance du Secteur Financier) requests a change after approval?

Any amendment that affects the funds risk profile, capital structure or investment policy must be submitted as a modification request. The CSSF will evaluate it on the same basis as the original submission.
