AIFM and management company support in Luxembourg, accounting, reporting and substance.

FSL supports AIFMs and ManCos on their back office: company accounting, regulatory reporting, substance and governance. Regulated management and authorisation remain with the authorised AIFM. FSL handles structuring, substance, accounting and reporting; CSSF authorisation and reserved acts are coordinated with our network of partner lawyers and notaries.

In short

AIFM/ManCo support covers the back-office functions of a Luxembourg alternative fund manager: management company accounting, regulatory reporting assistance, substance and governance. It does not constitute the exercise of regulated management.

Reviewed by Mickaël LOCManaging Director · Licensed accountant 10077274 · Updated August 6, 2026Profile LinkedIn

Legal basis

Law of 12 July 2013 on alternative investment fund managers (transposing the AIFM Directive 2011/61/EU), AIFMD II developments (Directive (EU) 2024/927); applicable CSSF circulars.

Key takeaway

FSL provides the back office; regulated management and CSSF authorisation sit with the AIFM.
A RAIF requires the use of a fully authorised AIFM.
ManCo substance is an increasing prudential focus.

Who this is for

Authorised and registered (sub-threshold) AIFMs
UCITS management companies and ManCos
Sponsors using a third-party AIFM (ManCo hosting)

What we do

Management company accounting and annual accounts
Regulatory reporting assistance (Annex IV, etc.)
Substance: office, staff, documented governance
