Operational support for Luxembourg fund formation

Once the legal and regulatory architecture is set by the appointed advisers, GP incorporation, AIFM and depositary workstreams, Lux GAAP accounts and tax filings need a coordinated operating calendar.

The fund layer and the deal layer are different mandates

This page covers the fund level. Deal-side SPVs have their own service path.

View all services

Fund-level work concerns the vehicle investors subscribe into and the sponsor entities around it. The deal-side layer below the fund covers acquisition SPVs, HoldCos and post-closing execution. Its natural path is the dedicated Private Equity SPV services page.

The reference reading for the fund layer starts with the Luxembourg SCSp as the default partnership form, and the RAIF as the dominant wrapper for new private equity and venture strategies. The manager side runs through the AIFM regime, including the registered or authorised status and the AIFMD II framework. It also covers the third-party AIFM route when the launch needs a platform rather than a proprietary authorised manager. It also runs through the general partner of a Luxembourg SCSp for the GP's own form, capital and economics.

On the tax side, carried interest taxation in Luxembourg frames the team's economics under the 2026 regime, and the reverse hybrid rules are the compliance point every SCSp with international investors should monitor.

Which entities does a Luxembourg fund launch involve?

A fund launch may involve several Luxembourg entities and regulated providers, each with distinct obligations.

The fund vehicle: SCSp or SCA

The partnership investors subscribe into. Contractual flexibility through the LPA, no legal personality for the SCSp, and a municipal business tax safe harbour when the AIF conditions are met.

Investor-facing vehicle

The RAIF wrapper where it fits

A recognised fund regime with umbrella compartments and subscription tax, reserved for well-informed investors and requiring an authorised external AIFM from launch.

Fund regime

The general partner entity

Usually a dedicated SARL. Form, capital, governance and the GP's stake are structural choices with tax consequences, including the safe harbour thresholds.

Sponsor side

Carry and team vehicles

Carried interest entities and team co-investment vehicles sit next to the GP and deserve the same accounting and governance discipline as the fund itself.

Team economics

The AIFM decision

Registered AIFM below the thresholds, own authorised AIFM, or a third-party AIFM platform: the choice shapes the timeline, passporting, governance and substance of the whole structure.

Regulatory anchor

Service provider bench

Depositary, fund administrator, auditor and legal counsel each carry a regulated role. The structure works when their outputs reconcile with the books and the filings.

Coordination

The scope of the fund-support engagement

The firm handles the Luxembourg corporate, accounting and tax work around the fund. Regulated roles remain with the appointed providers.

Included in the engagement

  • GP and sponsor-entity setup Incorporation coordination, RCS and RBE formalities, registered office setup and practical coordination with counsel.
  • Sponsor-side accounting Lux GAAP bookkeeping and annual accounts for the GP and carry vehicles, with capital-call and distribution entries reconciled to the administrator's records.
  • Tax compliance CIT, MBT and NWT returns, subscription tax where relevant, reverse-hybrid monitoring and withholding questions on distributions.
  • Governance and provider coordination Board documentation, annual approvals, RESA publications, KYC refreshes and alignment with the AIFM, depositary and administrator.

Out of scope stated upfront

  • Legal and regulatory design The appointed legal advisers define the fund documents, regulatory route and reserved legal analysis. The firm coordinates the surrounding workstreams.
  • AIFM and depositary roles These regulated functions remain with the appointed licensed providers and are not replaced by the engagement.
  • Fund administration and NAV production The fund administrator produces its own records and NAV work. The firm reconciles the sponsor-side books and statutory accounts with those inputs.

Frequently asked questions

Fund formation support in Luxembourg

Do I need a RAIF, or is a plain SCSp enough for a first fund?

A plain SCSp has no Luxembourg fund product law, whereas a RAIF adds statutory investor, AIFM, depositary, audit, minimum-assets and tax requirements and can use compartments. The choice depends on the investor perimeter, strategy, distribution route and operating model.

Do you replace the AIFM, depositary or fund administrator?

No. Those regulated roles stay with the appointed licensed providers. The support covers the Luxembourg corporate and financial workstreams around them: GP and carry-vehicle setup coordination, accounting, tax compliance and the records required for ongoing administration.

What must the operating model cover after a Luxembourg fund launches?

The operating model must align the AIFM, fund administrator, depositary where required, auditor, tax workstream, registered office and the GP's own accounts. The exact perimeter varies with the wrapper, strategy and investor base, and should be documented before the first closing.

Can a non-EU manager sponsor a Luxembourg fund?

Yes. A non-EU sponsor may use a Luxembourg SCSp or RAIF with an external authorised AIFM. Any marketing route must then be established under the AIFMD passport available through that AIFM or under the national private-placement rules applicable to the countries and investors concerned.
