A Luxembourg securitisation undertaking can take on any risk and fund it with notes or, since 2022, loans, in compartments that are legally ring-fenced. It needs CSSF authorisation only for more than three public issues a year below EUR 100,000 to non-professionals. A company-form vehicle pays 23.87% only on a small margin, because commitments to investors are deductible, with no withholding tax. Tranching brings in the EU Securitisation Regulation; active management raises the AIFMD question.
A ring-fenced box for any risk, funded by investors
A Luxembourg securitisation undertaking is a vehicle that buys assets or takes on risks and pays for them by issuing notes or, since 2022, by borrowing. What investors receive depends on how those assets perform. The vehicle has no business of its own; it holds the risk, collects the cash and passes it on.
The 2004 law was written for banks selling loan books, but it is drafted broadly. It covers any risk linked to claims, other assets or obligations, and it allows the vehicle to be split into compartments, each a separate pool with its own investors and its own creditors. The same law serves a bank's auto loans, a private credit warehouse, a structured note or a book of crypto-assets.
Most vehicles need no licence and no prior approval. A company-form vehicle pays corporate tax in principle, but can deduct everything it owes to its investors, so it is close to tax-neutral. Payments to investors bear no Luxembourg withholding tax. Those three features, flexibility, light supervision and neutrality, have made Luxembourg one of the main European homes for these vehicles.

What a securitisation undertaking can do
Any risk. The law defines securitisation as the acquisition or assumption, directly or through another entity, of risks relating to claims, other assets or obligations assumed by third parties, or inherent in all or part of the activities of third parties. The vehicle can buy assets outright (true sale), take risk synthetically through derivatives or guarantees, or lend to a company that holds the assets. Luxembourg law does not require tranching; a single class of notes is enough.
Funding by notes and loans. Before 2022 a vehicle had to finance itself by issuing securities, with other borrowing only on an ancillary basis. Now it may borrow wholly or partly, which suits private credit warehouses where a bank provides a senior facility and a sponsor the junior notes. The law also speaks of 'financial instruments' rather than 'securities', so instruments governed by foreign law fit more easily.
Active management, within limits. The CSSF used to accept only passive management. Since 2022 a vehicle may actively manage a portfolio of debt financial instruments, loans and other claims, itself or through a third-party manager, provided the acquisition is not financed by issuing to the public. Shares, real estate interests, crypto-assets and other non-debt assets are still to be held without discretionary trading. A vehicle that wants to trade equities at its own discretion is a fund, not a securitisation.
Legal forms. A securitisation company can be a public limited company (SA), a private limited company (SARL), a partnership limited by shares (SCA), a cooperative in SA form, a simplified company (SAS) and, since 2022, a general partnership (SNC), a common limited partnership (SCS) or a special limited partnership (SCSp). Minimum capital follows company law: EUR 30,000 for an SA, SCA or SAS and EUR 12,000 for an SARL; partnerships have none. Alternatively a securitisation fund can be set up as co-ownership or a fiduciary estate managed by a management company; it has no legal personality.
| Form | Capital | Tax status | Typical use |
|---|---|---|---|
| SARL | EUR 12,000 | Corporate tax, near-neutral | Private deals, few investors |
| SA | EUR 30,000 | Corporate tax, near-neutral | Listed notes, repackaging programmes |
| SCA | EUR 30,000 | Corporate tax, near-neutral | Sponsor control through the general partner |
| SCS / SCSp | None | Tax-transparent | Investors used to partnerships |
| Fund (co-ownership or fiduciary estate) | None | Tax-transparent | Managed by a management company |
Compartments. The articles or management regulations can create compartments, each matching a distinct part of the assets. Investors and creditors of one compartment have recourse only to its assets, and the assets of a compartment are not available to creditors of another.
Law and practice: Law of 22 March 2004 on securitisation, as amended by the Law of 25 February 2022 (Mémorial A, published 4 March 2022, in force 8 March 2022); Law of 10 August 1915 on commercial companies for the corporate forms; Law of 5 August 2005 on financial collateral arrangements for the definition of financial instruments.
When the CSSF steps in and what protects investors
The authorisation test. A vehicle needs CSSF authorisation only if it issues financial instruments to the public on a continuous basis. The 2022 law turned what had been CSSF practice into a statutory test with three parts. An issue is to the public if it is not reserved to professional clients, its denomination is below EUR 100,000 and it is not distributed by private placement. Issues are continuous if there are more than three of them in one financial year, counted across all compartments.
Most vehicles stay outside: notes of EUR 100,000 and above, or placed privately with professional investors, or issued three times a year or less, do not count. Borrowing under a loan agreement is not an issue to the public at all. An authorised vehicle must be managed by persons of good repute and experience, keep its assets with a credit institution as custodian, use a CSSF-approved auditor and report to the CSSF.
A prospectus is a separate question. A public offer or listing of notes on a regulated market needs a prospectus under the Prospectus Regulation, approved by the CSSF in its role as prospectus authority, whether or not the vehicle itself is authorised.
Bankruptcy remoteness. The law makes the usual structured-finance protections enforceable. Clauses by which investors and creditors subordinate their claims, waive the right to petition for bankruptcy or seize assets (non-petition), or limit their recourse to the assets of a compartment (limited recourse) are valid and binding. Since 2022 the law also sets a default ranking: debt ranks ahead of equity-type instruments unless the documents say otherwise, which protects investors where drafting is silent.
Investors' rights. Investors can appoint a fiduciary representative, often a professional trustee, to act for them. Security over the vehicle's assets may now secure any obligations relating to the securitisation. Assignments of receivables to the vehicle are effective against the debtor and third parties from the date of the agreement, unless agreed otherwise, which keeps the assets ring-fenced from the originator's creditors.
A Luxembourg SA issues structured notes linked to a basket of shares, in denominations of EUR 1,000, to private bank clients. In 2026 it makes three issues across two compartments: no authorisation. A fourth issue in December would make the issuance continuous, and the CSSF must authorise the vehicle before that issue. Raising the denomination to EUR 100,000 or restricting the issues to professional clients takes them out of the count.
Law and practice: Law of 22 March 2004, as amended in 2022, on authorisation of securitisation undertakings issuing to the public on a continuous basis, subordination, non-petition and limited recourse, fiduciary representatives and compartments; Regulation (EU) 2017/1129 (Prospectus Regulation); CSSF guidance on securitisation undertakings.
Fully taxable, close to neutral
A securitisation company in corporate form is a normal taxpayer: corporate income tax and municipal business tax, 23.87% combined in Luxembourg City in 2026 (22.80% planned for 2027 under budget bill no. 8800). What makes it neutral is a special rule in the securitisation law: commitments to investors and creditors are deductible, including payments to shareholders, which in another company would be dividends. The vehicle's income is matched by deductible payments and only a margin stays in Luxembourg.
| Tax | Company-form vehicle | Points to watch |
|---|---|---|
| Corporate income and municipal business tax | 23.87% in Luxembourg City (2026) | Taxable base is the margin after deductible commitments |
| Withholding tax on payments to investors | None | Payments are interest-like; 20% RELIBI tax only for some Luxembourg resident individuals |
| Net wealth tax | Exempt from the 0.5% tax | Minimum net wealth tax: EUR 535, EUR 1,605 or EUR 4,815 by balance sheet total, reduced by the prior year's corporate tax |
| Interest limitation | In scope (30% of EBITDA or EUR 3 million) | Exemption for securitisation special purpose entities under EU law, challenged by the Commission |
| Anti-hybrid rules | In scope | Deductions denied if payments are not taxed abroad due to a hybrid mismatch |
| VAT | Taxable person, usually no input VAT recovery | Management services exempt when specific and essential to the vehicle |
| Subscription tax, capital duty | None | Fixed registration duty on incorporation |
Transfer pricing and the margin. Because the vehicle passes almost everything to investors, the question is what it keeps. Luxembourg's transfer pricing circular for intra-group financing companies assumes a company that controls and bears risk, which a securitisation vehicle by design does not; for vehicles that hold third-party assets and are not part of a group, the circular is generally considered not to apply. Practice is a small, documented margin consistent with the vehicle's limited functions. Where the originator or sponsor is related, arm's length rules apply in full. Our note on transfer pricing in Luxembourg explains the documentation.
Interest limitation. Since 2019 Luxembourg limits exceeding borrowing costs to the higher of 30% of EBITDA or EUR 3 million. Company-form securitisation vehicles are in scope, except those that are securitisation special purpose entities under the EU Securitisation Regulation, which Luxembourg treats as financial undertakings. The European Commission considers that exemption contrary to ATAD and took Luxembourg to the Court of Justice (Case C-138/24); Advocate General Kokott proposed dismissal on 18 June 2026, and the judgment was pending when this note was written. For a vehicle that earns interest, the rule rarely bites, because interest income offsets interest-like expense. It bites when the vehicle earns dividends, gains, rents or crypto returns and pays interest-like returns: those payments are borrowing costs, while the income is not interest. See our note on interest limitation.
VAT. A securitisation vehicle is a taxable person, but its own activity is largely exempt, so it usually cannot recover input VAT. Luxembourg exempts the management of securitisation undertakings under Article 44 of the VAT law, in line with the exemption for special investment funds. Following the Court of Justice (Abbey National, C-169/04; GfBk, C-275/11; Fiscale Eenheid X, C-595/13), the exemption covers services that are specific and essential to managing the vehicle, such as portfolio management, administration and calculation, not general advice or legal work.
A Luxembourg SARL buys a EUR 50 million portfolio of SME loans yielding 7%: EUR 3.5 million interest a year. It pays EUR 0.4 million in servicing, administration and audit costs and EUR 2.4 million interest on senior notes. The rest, EUR 650,000 less an agreed margin of EUR 50,000, goes to the junior noteholder as a deductible return of EUR 600,000. Taxable profit is EUR 50,000; tax at 23.87% is about EUR 11,935. Net interest is positive, so the interest limitation rule does not bite. With a balance sheet above EUR 2 million the minimum net wealth tax is EUR 4,815, reduced by the previous year's corporate tax, so with a stable margin it is close to nil. The noteholders receive their returns without Luxembourg withholding tax.

The Securitisation Regulation and the AIFMD question
Securitisation Regulation. Regulation (EU) 2017/2402 applies to securitisations in its own, narrower sense: transactions in which the credit risk of an exposure or pool is tranched, payments depend on the performance of the exposures, and tranches rank so that losses fall on them in different ways. A Luxembourg vehicle with one class of notes, a pass-through repackaging or a vehicle financing a single asset is a securitisation under Luxembourg law but not under EU law.
Where it applies, the Regulation brings four main duties. The originator, sponsor or original lender retains a material net economic interest of at least 5%. The sell side discloses loan-level data, documents and investor reports, through a securitisation repository for public deals. Institutional investors, including banks, insurers, UCITS and AIF managers, carry out due diligence before investing. Sales to retail investors are restricted: suitability is required and, for portfolios not exceeding EUR 500,000, the minimum investment is EUR 10,000 and securitisation positions may not exceed 10% of the portfolio. A transaction can also qualify as simple, transparent and standardised (STS), which brings lower capital charges for bank and insurance investors.
The framework is being revised. The Commission proposed changes in June 2025 to simplify due diligence and transparency and to revise capital charges; the European Parliament adopted its position in May 2026 and trilogue negotiations were under way in the second half of 2026. Until an amending regulation is adopted and applies, the current rules stand.
The AIFMD question. A vehicle that pools investors' money and invests it under a defined investment policy for their benefit can be an alternative investment fund, with an authorised manager, a depositary and reporting. The AIFMD excludes securitisation special purpose entities, and in practice vehicles that issue only debt instruments, have no discretionary investment policy or simply transfer risk from one originator are not treated as AIFs. The risk rises with active management of a diversified portfolio, equity-type funding from several investors, and loan origination by the vehicle. Since the 2024 AIFMD amendments, loan-originating AIFs face their own rules, and a vehicle that originates loans as a business is more likely to be seen as a fund. If the economics look like a fund, a RAIF or SCSp may be the cleaner choice.
| Feature | EU Securitisation Regulation | AIF risk |
|---|---|---|
| Single class of notes, static assets | Does not apply | Low |
| Senior and junior tranches on a loan pool | Applies: retention, transparency, due diligence | Low, if an SSPE |
| Actively managed debt portfolio, notes to professionals | Applies if tranched | Medium: review the investment policy |
| Vehicle originates loans, equity funding from several investors | May apply | High |
| Repackaging of a single bond or basket | Does not apply | Low |
Law and practice: Regulation (EU) 2017/2402, Articles 2(1), 3, 5, 6 and 7; Directive 2011/61/EU (AIFMD), Article 2(3)(g), as amended by Directive (EU) 2024/927; Commission proposal of June 2025 amending Regulation 2017/2402, still in the legislative process; Luxembourg Law of 12 July 2013 on AIFMs.
Where the vehicle earns its keep
Repackaging. An arranger issues notes that give investors exposure to a bond, a basket of shares or a derivative strategy. A multi-issuance programme in an SA, with one compartment per series, lets a bank issue dozens of series a year without new companies. Example: a private bank wants a EUR 20 million note paying a fixed coupon linked to a basket of five listed bonds; the compartment buys the bonds, enters into a swap and issues EUR 100,000 notes to professional clients. No CSSF authorisation, no tranching, no Securitisation Regulation; a prospectus only if the notes are listed on a regulated market.
Private credit warehouse. A manager builds a loan portfolio before refinancing it. A bank lends 70–80% senior, the sponsor funds the rest with junior notes, and the vehicle buys loans as they are originated by others. The 2022 law allows the loan funding and active management of the pool; the tranching brings in the Securitisation Regulation, including risk retention.
Real estate holding. A vehicle can hold shares in companies that own property and issue notes to investors, with each building in a compartment. It must not develop or run the property itself. Real estate transfer taxes, the local tax on the properties and the interest limitation rule, since dividends and gains are not interest income, need careful planning. Compare our note on property companies.
Art, wine and collectibles. A compartment buys works or bottles and issues notes whose return depends on the sale price.
Crypto and tokenised assets. A vehicle can hold crypto-assets or tokenised instruments passively and issue notes, which may themselves be tokenised. Custody with a regulated provider, bank account opening and the MiCA position of anyone providing services around the vehicle are the practical issues; see our note on MiCA licences.
Insurance-linked risk. Insurance risk can be assumed through a reinsurance contract or a derivative, with the collateral held in the compartment.
- Term sheet and tax analysisAssets, funding, investors, tax margin and EU rules; two to four weeks.

- Running the vehicleAudited accounts, tax returns, Securitisation Regulation reporting if tranched.
Time and cost in general terms. An unregulated vehicle can be ready in four to eight weeks once the bank account opens; a CSSF-authorised one takes several months. Running costs are dominated by administration, audit, director and trustee fees, and do not grow much with deal size; for smaller deals, a compartment of an existing multi-issuer platform is often cheaper.

Luxembourg securitisation: frequent questions
Does a Luxembourg securitisation vehicle need a licence?
Only if it issues financial instruments to the public on a continuous basis. Since the 2022 reform that means more than three issues to the public in one financial year, counted across all compartments, where an issue is to the public if it is not reserved to professional clients, has a denomination below EUR 100,000 and is not a private placement. All other securitisation undertakings are unregulated, though their accounts must be audited.
Can a securitisation vehicle be financed by a loan instead of notes?
Yes. Since the Law of 25 February 2022 a securitisation undertaking may fund itself wholly or partly by borrowing, for example under a loan agreement, and not only by issuing notes or other financial instruments.
Can the portfolio be actively managed?
Yes, for a portfolio of debt financial instruments, loans or other claims, provided the acquisition is not financed by issuing financial instruments to the public. Other assets, such as shares, real estate interests or crypto-assets, are still to be held without discretionary management.
Is a Luxembourg securitisation vehicle tax-free?
No. A company-form vehicle is fully subject to corporate income tax and municipal business tax, 23.87% combined in Luxembourg City in 2026. Its commitments to investors and creditors, including returns paid on shares, are deductible, so the taxable result is usually a small margin. Payments to investors bear no Luxembourg withholding tax.
Do the interest limitation rules apply?
Generally yes for company-form vehicles, with the EUR 3 million safe harbour. Luxembourg exempts vehicles that are securitisation special purpose entities under the EU Securitisation Regulation; the European Commission challenges that exemption in Case C-138/24, where the Advocate General proposed on 18 June 2026 that the action be dismissed. The judgment was pending when this note was written.
Is every Luxembourg securitisation vehicle subject to the EU Securitisation Regulation?
No. The Regulation applies only where the credit risk of an exposure or pool is tranched. A single-class repackaging or a pass-through vehicle is a securitisation under Luxembourg law but not under EU law.
