A Luxembourg securitisation undertaking converts the risks or returns of assets into obligations owed to investors or lenders. The vehicle can acquire assets directly, assume risks through another arrangement or use an acquisition and issuance structure. The financing may take the form of financial instruments or borrowing.
The legal framework is the Law of 22 March 2004, substantially updated in 2022. The first practical question is whether the transaction falls within that law. The next is whether the vehicle will issue to the public on a continuous basis and therefore require CSSF authorisation.
The securitisation concept
The 2004 Law covers operations in which an undertaking acquires or assumes risks linked to claims, other assets or obligations of third parties, then finances those risks through instruments or borrowing whose value or yield depends on them.
This definition can cover loans, receivables, debt securities, equity interests and other identifiable risks. It also recognises structures in which one undertaking acquires the risks and another finances them. The legal documents must connect the assumed risk, the financing and the payment waterfall.
The ECB recorded 1,805 financial vehicle corporations resident in Luxembourg in the second quarter of 2026 in its official statistical tables. That statistical category does not replace the legal test under the 2004 Law, but it shows the scale of the reporting population.
Legal forms and funding
A securitisation company may use several corporate forms, including an SA, SARL, SCA or SAS, as well as certain partnerships. A securitisation fund has no legal personality and is managed by a management company. Since the 2022 reform, both financial instruments and borrowing can finance the operation.
Active management is possible for a pool of debt securities, debt financial instruments or claims when the instruments issued to finance that pool are not offered to the public. This condition matters for managed credit strategies. It should not be generalised to every asset class or distribution model.
The CSSF authorisation test
Most Luxembourg securitisation vehicles are not authorised by the CSSF. Authorisation is required only when financial instruments are issued to the public and on a continuous basis. Both elements must be present.
The CSSF authorisation guidance explains that continuous issuance means more than three public issues during one financial year, counted across all compartments. An issue is not public for this test when it is addressed to professional clients, uses denominations of at least EUR 100,000 or is distributed as a private placement.
| Distribution pattern | General position under the authorisation test |
|---|---|
| Three or fewer public issues in a financial year | Not continuous on that basis |
| More than three public issues in a financial year | Continuous |
| Professional-client distribution | Not public for this test |
| Denomination of at least EUR 100,000 | Not public for this test |
| Private placement | Not public for this test |
An unregulated vehicle remains subject to company, accounting, tax and statistical rules. It is simply outside CSSF prudential supervision under the securitisation authorisation test.
Compartments and creditor rights
The constitutional documents may allow separate compartments. Each compartment can hold a distinct asset pool, issue its own financing and apply its own payment waterfall. Assets allocated to one compartment are reserved for the claims linked to that compartment, subject to the constitutional documents and the law.
Limited-recourse, subordination and non-petition clauses receive statutory recognition. A compartment may be liquidated separately without automatically liquidating the others. These protections depend on accurate allocation. Contracts, bank movements and accounting records must consistently identify the relevant compartment.
Tax treatment
A securitisation company formed as a taxable capital company is generally subject to corporate income tax and municipal business tax. The specific tax treatment treats commitments assumed towards investors and other creditors as operating expenses. These capital companies are exempt from ordinary net wealth tax but remain subject to minimum net wealth tax.
Payments and instrument terms must be reviewed rather than labelled automatically. The deduction, withholding-tax and VAT outcomes depend on the legal form, the nature of the commitment and the services supplied. A securitisation partnership or fund may follow a different direct-tax analysis from a company.
Annual accounts and audit
Every securitisation undertaking must have its accounts audited by one or more approved statutory auditors under the 2004 Law. This requirement applies even when the vehicle is not authorised by the CSSF. Where compartments are financed by shares or partnership interests, the constitutional documents may provide for compartment-level balance sheets and profit and loss accounts to be approved by the holders of that compartment.
Corporate vehicles file their approved accounts through the RCS under the applicable accounting rules. Tax returns and corporate approvals follow their own calendars. An authorised undertaking also sends the CSSF the information and reports required for supervision.
Statistical reporting
A vehicle that meets the statistical definition of a financial vehicle corporation enters the reporting framework of the Luxembourg central bank. The BCL reporting page provides the applicable instructions and forms.
This reporting is separate from CSSF authorisation. An unregulated securitisation undertaking may therefore have BCL reporting obligations even though it has no prudential reporting to the CSSF. Classification should be completed when the transaction becomes operational, then revisited if the assets or financing change.
Conclusion
The Luxembourg securitisation framework combines a broad risk-transfer definition, flexible funding and legally protected compartments. The main regulatory dividing line is public and continuous issuance. Unregulated status removes CSSF prudential supervision, not the audit, accounting, tax or statistical obligations that apply to the vehicle.

Frequently Asked Questions
When does a Luxembourg securitisation undertaking need CSSF authorisation?
Authorisation is required when the undertaking issues financial instruments to the public on a continuous basis. Both conditions must be met. Continuous issuance means more than three public issues during one financial year, counted across the undertaking's compartments.
What does the public issuance test exclude?
An issue is not treated as public for this test when it is addressed to professional clients, uses financial instruments with denominations of at least EUR 100,000, or is distributed as a private placement. The transaction documents and distribution process must support the classification.
Can a securitisation vehicle actively manage assets?
Active management is permitted for pools of debt securities, debt financial instruments or claims when the financing instruments are not offered to the public. Other asset and issuance structures remain subject to wider statutory limits.
How is a Luxembourg securitisation company taxed?
A securitisation company formed as a taxable capital company is generally subject to corporate income tax and municipal business tax. Commitments to investors and other creditors are treated as operating expenses under the specific tax rule. The company is exempt from ordinary net wealth tax but remains subject to minimum net wealth tax. Partnerships and funds require a separate analysis.
Does an unregulated vehicle still need an audit?
Yes. The annual accounts of every securitisation undertaking are audited by one or more approved statutory auditors. CSSF authorisation adds prudential supervision but is not the source of the basic audit requirement.
