The Luxembourg securitisation vehicle under the 2004 law

Securitisation is one of the quiet pillars of the Luxembourg financial centre. The European Central Bank counted 1,766 financial vehicle corporations resident in Luxembourg in the first quarter of 2026, the largest population in the euro area ahead of Ireland.¹ Behind that figure sits the law of 22 March 2004, a regime built on three ideas — contractual freedom, statutorily protected compartments and tax neutrality — substantially modernised by the law of 25 February 2022.²

For a sponsor structuring repackaging notes, a CLO, an insurance-linked programme or a private credit warehouse, the Luxembourg questions are always the same. Does the transaction fit the legal definition, does the vehicle need CSSF authorisation, how do compartments protect investors, and what does the vehicle owe the authorities each year once it is live.

What counts as securitisation under the 2004 law

The statutory definition is deliberately wide. Securitisation is the operation by which a vehicle acquires or assumes, directly or through another undertaking, risks relating to claims, other assets or obligations assumed by third parties, and finances itself by issuing financial instruments or, since 2022, by contracting any form of borrowing whose value or yield depends on those risks.²

Three consequences follow. Almost any asset class can be securitised, from receivables and loans to equity stakes, real assets or whole business risks. Funding is no longer tied to securities issuance, so a vehicle can be financed entirely by loans. And two-vehicle structures are expressly recognised, with an acquisition vehicle assuming the risks and an issuance vehicle funding it, both able to opt into the law.

The legal wrapper is a choice, not a constraint. A securitisation company can be an SA, SCA, Sàrl, SAS, a cooperative organised as an SA or, since 2022, a partnership — SNC, SCS or SCSp. The alternative is a securitisation fund without legal personality, managed by a management company and registered with the RCS since the 2022 reform.

Regulated or unregulated, the public-issuance test

CSSF authorisation is the exception, not the rule. It is required only for vehicles that issue financial instruments to the public on a continuous basis, both conditions now defined in the law itself.²

Continuous means more than three issuances offered to the public during a financial year, counted at the level of the vehicle across all compartments. An issuance is not made to the public when it is reserved to professional clients, when denominations reach at least €100,000, or when it is distributed by private placement. A vehicle that stays on the right side of any one of these markers for each issue, or keeps its public issues at three or fewer per year, remains unregulated, with no CSSF approval, no prudential reporting and a materially lighter operating cost. The CSSF counted only 26 authorised securitisation undertakings at the end of May 2026, a fraction of the market.³

The 2022 reform also settled a commercial question by codifying active management. A vehicle may securitise a pool of debt securities, debt instruments or claims that is actively managed, by itself or a third party, provided the instruments financing the pool are not offered to the public. Luxembourg CLOs and actively managed credit repackagings rest on this provision.

Compartments, limited recourse and non-petition

The compartment regime is the structural heart of the law. The constitutional documents may allow the management body to create compartments, each corresponding to a distinct part of the vehicle’s estate. Investors and creditors whose rights arise in connection with a compartment have recourse only to the assets of that compartment, and those assets answer exclusively for the claims of that compartment’s investors and creditors. Between investors, each compartment is treated as a separate entity unless the documents provide otherwise.²

Two contractual protections receive statutory force. Limited-recourse and subordination provisions are expressly enforceable, with a default statutory ranking that the parties can freely reorder. Non-petition clauses, by which parties undertake not to seize the vehicle’s assets and not to petition for its bankruptcy, are backed by a hard sanction, since proceedings introduced in breach are declared inadmissible. Since 2022, a company’s articles may also provide that the accounts of a compartment are approved only by the shareholders of that compartment, with distributable amounts determined compartment by compartment.

Each compartment can be liquidated separately without affecting the others, which is what allows a single platform to run successive transactions for different arrangers over many years — and what makes disciplined per-compartment accounting the operational core of the vehicle’s annual compliance.

The tax treatment of a securitisation company

A securitisation company is a fully taxable Luxembourg company, subject to corporate income tax and municipal business tax, with treaty access on that basis. Neutrality is engineered on the deduction side. Commitments assumed towards investors and any other creditors are deductible operating expenses under article 46, number 14 LIR, so the taxable base reduces to the margin the vehicle actually retains.⁴

Payments to investors follow the same logic. All distributions by a securitisation vehicle qualify as interest-type income from movable capital rather than dividends, which keeps them outside the scope of Luxembourg dividend withholding tax, and ordinary interest bears no withholding either. The company is excluded from tax consolidation, and exempt from net wealth tax except for the minimum net wealth tax, which since 2025 depends only on the balance-sheet total and reaches €4,815 above €2 million.⁴ No subscription tax applies to securitisation companies, and a securitisation fund is expressly exempt from it. Management services supplied to the vehicle are VAT-exempt under article 44 of the VAT law.

One point deserves precision rather than reflex. Securitisation entities within the meaning of the EU Securitisation Regulation are still on the list of financial undertakings excluded from the interest limitation rule of article 168bis LIR. The European Commission challenged that carve-out before the Court of Justice, and in June 2026 the Advocate General proposed dismissing the action, the judgment remaining pending.⁵ Vehicles outside the EU regulation’s definition never benefited from the carve-out, so heavily leveraged structures should still model the 30% EBITDA and €3 million mechanics.

The annual obligations of every vehicle

Unregulated does not mean unsupervised bookkeeping. Every securitisation undertaking prepares annual accounts under Luxembourg accounting law, and the accounts must be audited by an approved statutory auditor — a réviseur d’entreprises agréé — whether or not the vehicle is CSSF-authorised.² Accounts are filed with the RCS, tax returns are due like those of any taxable company, and the management report must disclose material information affecting investors’ rights.

Vehicles that meet the ECB definition of a financial vehicle corporation additionally report quarterly statistics to the Luxembourg central bank under Regulation (EU) No 1075/2013, covering the balance sheet and transactions of the securitised portfolio.¹ Only authorised vehicles add CSSF reporting, including per-compartment financial information and issuance lists.

The regime keeps evolving in the same direction. A bill filed with Parliament in June 2026 proposes to widen funding to any form of financial commitment, to allow a compartment to invest in other compartments of the same vehicle and to extend active management beyond debt pools. For sponsors, the message of two decades of Luxembourg securitisation practice is continuity, a legal platform designed around the transaction documents, with the operating discipline — accounting by compartment, audit, tax and statistical filings — as the price of that flexibility.
