The Islamic Finance and Markets Law Review: Luxembourg


The Grand Duchy of Luxembourg (Luxembourg) has long embraced Islamic finance as an important area of international finance and has taken an active role in fostering cooperation with firms and institutions engaged in shariah-compliant transactions. To create an environment conducive to the carrying out of such transactions in or via Luxembourg, Luxembourg has undertaken multiple initiatives designed to identify the particular needs of Islamic financial players and how they can be catered for. Often-cited examples of Luxembourg's credentials as an Islamic finance centre include the establishment in Luxembourg, in 1978, of the first Islamic finance institution in a non-Muslim country (the Islamic Banking System); authorising, in 1983, the first shariah-compliant insurance company in Europe; and the listing, in 2002, of sukuk on the Luxembourg Stock Exchange for the first time in Europe.2 More recently, in 2009, the Luxembourg Central Bank (BCL), as the first European central bank, joined the Islamic Financial Services Board, an international organisation promoting the stability of the Islamic financial services industry by issuing global prudential standards and guiding principles, and the following year the BCL became one of the founding members of the International Islamic Liquidity Management Corporation.3

One of the conclusions reached on the basis of the research conducted by various working groups set up under the auspices of the government was that Luxembourg's legal system provides investors and promoters interested in shariah-compliant products with a choice of suitable vehicles.4 The confirmation of the tax treatment of shariah-compliant vehicles and the development of best practice guidelines for Islamic financial services followed soon afterwards.5 The time and effort put in by Luxembourg's financial services sector into growing its Islamic finance competencies have paid off: Luxembourg has become a prime location for the listing of sukuk and is seen as the leading non-Muslim domicile for shariah-compliant investment funds with over US$3 billion of assets under management and, in terms of the number of Islamic funds set up in the market, Luxembourg is the largest Islamic fund hub outside the Muslim world with 161 shariah-compliant funds domiciled in Luxembourg.6

Legislative and regulatory framework

In Luxembourg, there are no laws dedicated specifically to Islamic financial products or services. The existing legal framework has proved both flexible and innovative enough to accommodate the demands of Islamic financial practitioners, implementing various shariah-compliant structures through the use of Luxembourg vehicles and legislation. It is also relatively common and straightforward to combine, in a single transaction, elements of Luxembourg law with foreign law-governed agreements and structuring tools, such as, for instance, a trust governed by English law. Although it currently has no equivalent under Luxembourg law, an English law trust will generally be recognised, subject to certain conditions, by Luxembourg courts on the basis of the Convention on the law applicable to trusts and on their recognition concluded at The Hague on 1 July 1985. An English law trust declared in favour of sukuk holders over the underlying assets held by the issuer of sukuk will allow sukuk holders to retain a form of ownership over those underlying assets as prescribed by shariah law.

i Legislative and regulatory regime


The regulatory regime applicable to credit institutions in Luxembourg is mainly shaped by the European directives and regulations dealing with the banking and investment sectors,7 as further completed by national law. All the provisions and requirements in force in Luxembourg relevant for credit institutions would apply to Islamic banks as no specific regime is provided, or indeed required, for this type of institution. This was confirmed by the findings of a cross-sector taskforce set up by the government in 2008. The relevant provisions of European law are implemented in large part in the Luxembourg act of 5 April 1993 on the financial sector, as amended (the Banking Act), and in the Luxembourg act of 18 December 2015 on the failure of credit institutions and certain investment firms, as amended.

According to the Banking Act, no person established under Luxembourg law may carry on the business of a credit institution without holding a written authorisation from the Commission de Surveillance du Secteur Financier (the CSSF), which is the Luxembourg banking and financial supervisory authority. This licensing requirement to carry out banking and financial activities also applies to Islamic banks. Since 2014, Luxembourg has been a participating member of the Single Supervision Mechanism (the SSM), which means, among other things, that entities willing to carry out banking activities in and from Luxembourg must obtain their licence from the European Central Bank (the ECB) through the services of the CSSF (which remains the point of entry for licence applications).

Except for covered bond banks (the exclusive activity of which is to issue covered bonds), Luxembourg banks (including Islamic banks) qualify as universal banks (which means that Luxembourg credit institutions are authorised to carry out any activity of the financial sector). According to the principle of the European passport, a Luxembourg bank may provide services, either through a branch or on a cross-border basis, in any other country of the European Economic Area (EEA) without any further licensing requirement in a host country. A Luxembourg branch of a third-country institution (from outside the EEA) would, however, require a specific type of licence in Luxembourg, which would not allow it to benefit from the European passport.

Luxembourg banks are subject to two main sets of requirements: those relating to prudential supervision aimed at preventing systemic risks; and those relating to investors' and clients' protections that mainly stem from Directive 2014/65/EU8 and the EU consumer protection rules.

The prudential regulation imposes a number of requirements and ratios in terms of internal governance, own funds, liquidity and risk management, whereas the client and investor protection corpus requires certain conduct of business rules to be implemented and a high level of contractual formalism when dealing with clients.

As mentioned above, the CSSF is Luxembourg's national competent authority for banks with respect to both the prudential aspects and the client protection aspects. However, in the context of the SSM, the competence of the CSSF in relation to prudential matters is delegated to it by the ECB, which is now, as a matter of principle, the competent supervisory authority in the eurozone. Any credit institution that will qualify as a significant institution would be under the direct supervision of the ECB for those aspects. The CSSF remains the competent authority for less significant institutions.

Investment funds

Shariah investment funds may be set up under the general legal framework applicable to investment funds in Luxembourg as there is no specific legal requirement concerning these products.9 Therefore, these funds fall, depending on their structure, within the scope of the Companies Act,10 the Alternative Investment Fund Managers Act (AIFM Act)11 or one of the Product Acts, or a combination of these.12 The Association of the Luxembourg Fund Industry (ALFI) has also published a set of best practice guidelines for setting up and servicing Islamic investment funds,13 which have become an international standard in the financial sector.14 Thus, from a supervisory and regulatory perspective, there is no particular distinction between a shariah investment fund and any other type of fund.

The common regulatory principles applicable to managers of a regulated investment fund or its regulated external manager set up under Luxembourg law must also be fulfilled. For these investment funds and asset managers, shariah board members must therefore be of sufficiently good repute and be sufficiently experienced in relation to the investment policy of the concerned investment fund.15 The administrative practice for regulated funds is constantly changing. For instance, for regulated funds the CSSF requires that a board member be specifically designated as being in charge of anti-money laundering and counter terrorist financing (AML/CFT) matters, even where this function is delegated, and this therefore would require specific AML/CFT knowledge. Equally, the CSSF also requires that board members dedicate sufficient time to a regulated fund, and it may control the number of directorship mandates and time allocated per mandate by the board members. This rule has already been set in a circular for certain internally managed funds and asset managers, and limits managing members to a maximum of 20 mandates and 1,920 hours per year.

Capital markets

Traditional shariah-compliant structures can be replicated using Luxembourg vehicles, with the full benefits of the applicable Luxembourg tax and legal regime. A Luxembourg securitisation undertaking subject to the Securitisation Act16 (discussed in more detail below) is frequently the vehicle of choice for clients who seek to raise finance in compliance with shariah principles, in particular using murabahah and ijarah structures.17

As regards the offering of securities in Luxembourg – whether by way of private placement, an offer to the public or admission to trading on the regulated market or the Euro MTF market of the Luxembourg Stock Exchange, the same rules apply to sukuk as to conventional bonds. While private placements are not subject to any regulation and can be carried out without any form of offering document, an offer of securities to the public will (unless an exemption is available) have to be conducted in accordance with the Prospectus Regulation,18 which requires the publication of a prospectus drafted in accordance with the Prospectus Delegated Regulations.19 The Prospectus Regulation also requires a prospectus to be published in connection with the admission of securities to trading on the regulated market of the Luxembourg Stock Exchange. Once approved in Luxembourg by the CSSF (in circumstances where Luxembourg is the issuer's home Member State within the meaning of the Prospectus Regulation), a prospectus prepared in compliance with the Prospectus Regulation and the applicable annexes of the Prospectus Delegated Regulations can be used for public offers or admission to trading on regulated markets in other countries of the EEA without the need for a separate approval from the local competent authorities (subject to the CSSF notifying the competent authorities of its approval). Issuers of securities traded on the regulated market of the Luxembourg Stock Exchange will have to comply with the highly harmonised ongoing obligations relating to transparency and prohibition of market abuse. Alternatively, securities may be admitted to trading on the Euro MTF market of the Luxembourg Stock Exchange, which is not included in the list of regulated markets published by the European Commission, but which has built up a strong international reputation among issuers and investors. An offering circular to be prepared in connection with trading on the Euro MTF market will be approved by the Luxembourg Stock Exchange, and it must comply with the disclosure requirements set out in the Rules and Regulations of the Luxembourg Stock Exchange: these requirements are lighter than those under the Prospectus Regulation, but they do not offer the possibility of passporting the offering circular to other jurisdictions. The Rules and Regulations of the Luxembourg Stock Exchange also prescribe most of the ongoing disclosure requirements applicable to issuers of securities admitted to trading on the Euro MTF market.

Those interested in issuing or investing in sukuk should note that the Luxembourg Stock Exchange is a prime listing location for sukuk in Europe. At the end of 2016, the aggregate amount of sukuk traded on the markets of the Luxembourg Stock Exchange reached US$95 billion.20 Issuers of sukuk who have chosen the Luxembourg Stock Exchange come from Muslim countries as well as Europe, Hong Kong, South Africa and the United States.21

ii Regulatory and supervisory authorities

In Luxembourg, there is no office or authority charged with the supervision and monitoring of Islamic financial transactions or market participants using shariah-compliant structures. The CSSF is a secular institution, which will treat Islamic financial transactions in the same way as any other financial activity subject to its supervision. The extent of the CSSF's supervisory role is very broad and covers a wide range of actors in the financial sector, including regulated investment funds (also those that are shariah-compliant), regulated securitisation vehicles and credit institutions, to name just a few (but excluding insurance undertakings, which are supervised by the Insurance Commission). If a particular project falls within the scope of the CSSF's competence, the regulator will aim to ensure compliance with all relevant Luxembourg laws and regulations. Whether a project also meets the conditions set under shariah law would, from a Luxembourg law perspective, be a matter of contractual arrangements between the parties.

Common structures

i Investment funds

In Luxembourg, a large variety of shariah-compliant vehicles are available to asset managers and investors. The choice of investment structure depends on the investment policy, the investors targeted and the level of regulation desired. Shariah-compliant asset allocation can be achieved by setting out a strong investment strategy together with a shariah-oriented selection process. For instance, a shariah-compliant fund must follow the principles of equal treatment of shareholders and the prohibition of undue enrichment. In practice, this means that shares subscribed for by investors must be of equal value. Consequently, preference shares in an investment company (generally permitted under the Companies Act) are not allowed.22

From a legal standpoint, any Luxembourg investment vehicle can be used to set up a shariah-compliant fund. Generally, a Luxembourg investment fund can take either a corporate form23 or a contractual form.24

From a regulatory standpoint, shariah-compliant investment funds can either be structured as undertakings for collective investment in transferable securities (UCITS) governed by Part 1 of the UCI Act of 17 December 201025 or alternative investment funds (AIFs) within the meaning of the Directive 2011/61/EU, as amended (AIFMD). The main difference between the two kinds of funds is that only UCITS can be marketed on a pan-European cross-border basis to retail and professional clients under the UCITS passport, whereas AIFs can principally only be marketed to professional investors26 under the AIFMD passport.27 Certain specialised investment funds (SIFs) and investment companies in risk capital (SICARs) may not qualify as AIFs.

A SIF is a lightly regulated, operationally flexible and fiscally efficient multipurpose investment fund for a pool of well-informed investors.28 Even though a SIF does not have to comply with specific investment restrictions, it must follow the principles of risk diversification.29 A SICAR is a regulated and tax-efficient structure specifically designed for private equity and venture capital investments.30 In contrast to a SIF, a SICAR may concentrate its assets in one single project as long as it invests exclusively in risk capital. Investments of a SICAR must be characterised by a high risk and an intention to develop the target entities. A reserved alternative investment fund (RAIF) is a vehicle reserved to well-informed investors encompassing the characteristics and structuring flexibilities of SIFs or, alternatively, SICARs, without being subject to any regulatory approval or supervision by the CSSF. The supervision is, however, operated indirectly as the manager must be regulated under the AIFMD.

Another option available to shariah promoters and investors is a Part II Fund, which is a flexible but regulated vehicle open to both retail investors and professional investors. Part II Funds must invest their assets according to the principles of risk diversification but are not limited as to the type of assets into which they can invest.

UCITS are open-ended funds investing in transferable securities such as units, bonds, money-market instruments and certain types of derivatives. These funds are harmonised at EU level and widely sold to Islamic investors. The UCITS regime lays down common requirements for the organisation, management and oversight of such funds and imposes rules relating to diversification, liquidity and use of leverage. UCITS offer, therefore, high levels of investor protection. For further illustration purposes, government mudarabah certificates (i.e., a non-debt-creating mode of finance issued by the sovereign state) and commodity murabahah deposit (i.e., a short-term fixed income deposit) would generally qualify as eligible investments for UCITS.31 However, specific consideration should be given to commodity murabahah, as the CSSF would only consider these as UCITS-eligible investments if the issuer is a credit institution that has its registered office in the EU or a non-EU state with equivalent rules.32

Regardless of what fund products shariah promoters elect to use, they may always incorporate shariah features in relevant fund documentations, such as:

  1. the shariah principles will always be complied with and a ramp-up period is not applicable;
  2. a ban on investment in any interest-bearing assets or debt instruments and cleansing of cash and dividends receipts. A fund may utilise shariah-compliant financing either at the individual asset level or at the fund level, but it will place low reliance on generating returns from such financing;
  3. a ban on futures or forward contracts, derivatives or short sales;33
  4. all non-shariah-compliant earnings from the fund shall be contributed to Islamic charities and other available methods for disposal of the fund's assets that are no longer shariah-compliant;
  5. a prohibition on investments related to haram activities such as gambling, alcohol and tobacco (including the advertising and marketing of these activities);
  6. creation of a shariah advisory board or engagement of a shariah adviser, or both, to ensure that the fund and the investments will be structured in compliance with the principles of shariah; 34
  7. the conduct of regular reviews or audits, or both, on shariah compliance;
  8. specific risk disclosures in connection with shariah compliance; and
  9. the above shariah-compliant nature shall also be reflected in the service agreements and documents with service providers of the fund. For example:
    • the investment management agreement shall include a decision-making process and a specific investment screening process to ensure the shariah-compliance;
    • the central administration agreement shall acknowledge specific pricing and valuation techniques applicable to Islamic assets;35 and
    • special attention should be paid to the fact that no interest should be charged in the depositary agreement.

ii Real estate and private equity investments

Real estate and private equity investments are characterised by their long-term and illiquid nature. The financing aspect of these investments is challenging because shariah law prohibits the use of conventional debt structures. In Luxembourg, this challenge can, however, be overcome by using alternative shariah-compliant instruments, such as sukuk al-murabahah (i.e., sales-based financing) or sukuk al-ijarah (i.e., lease-based financing) to finance the acquisition of assets.36

With respect to leverage, under shariah law, debt financing and the payment of interest are proscribed (riba).37 In practice, however, it is usually accepted that a shariah-compliant fund may engage in leverage through the use of shariah-compliant financing instruments.38 Conventional loans or interest-bearing instruments are not permitted. It is also conceivable to open investment to additional equity-based investors using a musharakah contract whereby each investor has management rights in proportion with its investment in the fund.39 shariah-compliant property investments can also be achieved by using a mudarabah or an ijarah contract.40 The mudarabah contract is similar to the relationship between a Luxembourg general partner (i.e., fund manager) and the limited partners (i.e., investors).41 By contrast, an ijarah contract is a lease contract for a specified asset or the usufruct of a specified asset.42 The rules governing ijarah may be considered similar to those governing conventional leases,43 subject to limitations provided for by the shariah law.

iii Capital markets

Benefits of the Luxembourg securitisation regime

Many issuances of sukuk in Luxembourg have been structured using a Luxembourg securitisation undertaking subject to the Securitisation Act. The securitisation undertaking may be set up in the form of a company or a securitisation fund managed by a Luxembourg management company. Securitisation funds do not have legal personality; they are constituted by one or more co-ownerships of assets or fiduciary estates, which provide a closer connection between the investors and the underlying assets – a considerable advantage from the point of view of shariah law.44 While the vast majority of securitisation undertakings are unregulated, a securitisation undertaking that offers securities to the public more than three times per year has to apply for a licence from the CSSF to qualify as a regulated securitisation vehicle for the purposes of the Securitisation Act.

A securitisation undertaking's primary activity must be to engage in securitisations, defined by the Securitisation Act as transactions whereby a securitisation undertaking:

  1. acquires or assumes, directly or through another undertaking, risks; and
  2. to finance the acquisition or assumption of those risks, issues securities whose value or yield depends on those risks. Risks to be securitised may be related to all kinds of assets, including claims, receivable or equity interests, with no requirement of risk diversification.

Unlike funds, securitisation undertakings must not actively manage securitised assets. The Securitisation Act allows a securitisation undertaking to set up multiple compartments by a simple decision of its board of directors. Each compartment forms a distinct and independent part of the securitisation undertaking's assets and is segregated from its other compartments and general estate. One or more securitisations can be carried out independently out of each individual compartment, which significantly reduces transaction costs as one vehicle can be used for an unlimited number of distinct transactions. For instance, it would be possible for one securitisation undertaking to create several compartments, some of which would be dedicated to shariah-compliant transactions, while the other compartments could be used for issuing conventional securities. Investors (irrespective of whether they hold equity or debt securities) will only have recourse to the assets comprised in the compartment to which the securities they hold have been allocated.

A securitisation vehicle is considered insolvency remote, a feature much valued by rating agencies. The main characteristics of Luxembourg's sophisticated securitisation regime – the ringfencing of compartment assets, priority of payments, limited recourse, prohibition of seizure of assets and non-petition for bankruptcy – are protected not only by contractual arrangements, but are also expressly recognised by the Securitisation Act. Legal proceedings initiated against a securitisation undertaking in breach of the provisions relating to the priority of payments, prohibition of seizure of assets and non-petition for bankruptcy will, in principle, be declared inadmissible by a Luxembourg court.

It should also be mentioned that a securitisation undertaking issuing exclusively debt instruments (and sukuk is regarded as such from a Luxembourg law perspective) will be able to rely on an exemption from the scope of the AIFM Act. Other exemptions from the AIFM Act may also be available.

Raising finance in a shariah-compliant manner

One of the popular Islamic finance structures that have been put in place in Luxembourg using a securitisation vehicle is murabahah. A pioneering transaction, which combined a reducing revolving convertible murabahah with a note issuance, involved a Luxembourg securitisation company that acted both as the issuer of conventional bonds and as the lender under the murabahah facility. The issuer used the proceeds of the bonds to purchase certain commodities, which it subsequently sold, on deferred payment terms, to an Islamic investment bank for a sale price equal to the acquisition cost plus profit. The cash payments of the deferred sale price were used by the issuer to meet its obligations towards the bond investors. Additionally, the bondholders had the option to convert the cash distributions due to them under the bonds into shares of the lender under the murabahah contract (which constituted the securitised asset for the purpose of the bond issue).

Luxembourg issuers, some of them ordinary companies as opposed to securitisation undertakings, are regularly used to issue sukuk, the proceeds of which may be invested, directly or indirectly, in assets such as real estate or aircraft. A stream of rental income generated by those underlying assets is then distributed to investors via payments under the sukuk. Notably, Luxembourg has played host to a joint venture formed among prominent Islamic and conventional financial actors who invested, through a mixture of equity and sukuk, in a Luxembourg special purpose vehicle (LeaseCo) to acquire a string of retail properties leased to tenants. In return for the right to control the target properties and receive rents, the LeaseCo paid the issue proceeds of the sukuk to a Luxembourg joint venture vehicle (PropCo), thereby enabling it to purchase the shares of the company whose subsidiary owned the relevant properties. Any rewards associated with the ownership of the properties were to be extracted by the joint venture members via payments made by the LeaseCo in respect of the sukuk.

Another example of the successful application of Luxembourg law in the implementation of Islamic financial transactions is the issue of sukuk using a two-tier securitisation structure by an international Islamic organisation. This type of set-up is expressly permitted under the Securitisation Act and involves two securitisation undertakings: an issuing vehicle and an acquisition vehicle. In the case at hand, the issuing vehicle issues, on an ongoing basis, trust certificates and contributes the proceeds to the acquisition vehicle in exchange for the undivided beneficial ownership interest in shariah-compliant assets purchased by the acquisition vehicle using the contribution from the issuing vehicle. Those assets are held by the acquisition vehicle for the benefit of the issuing vehicle under an English law trust. The issuing vehicle, for its part, holds the undivided ownership interest on trust for the holders of the trust certificates as well as acting as their agent (wakeel). Through its undivided beneficial ownership, the issuing vehicle is entitled to receive profits and redemption amounts generated by the underlying assets and uses the sums so received to honour its obligations under the trust certificates.

One of the prominent issuers of sukuk is the state itself, which, in 2014, became the first eurozone country to issue sovereign sukuk. For the purpose of the transaction, Luxembourg arranged for the setting up, and became the sole shareholder of, Luxembourg Treasury Securities SA, a special purpose vehicle that has acted as the formal issuer of the instruments. The Luxembourg sukuk, which is of the al-ijarah type, is backed by three administrative buildings that have been purchased by the issuer from the state using the issue proceeds of the sukuk. The buildings will be transferred back to the state for a pre-agreed purchase price when the sukuk matures. The Luxembourg sukuk have been admitted to trading on the Euro MTF market of the Luxembourg Stock Exchange.45


Whereas there is no specific framework regulating Islamic finance transactions in Luxembourg from a legal perspective, there are two circulars issued by the directors of the direct tax administration and the indirect tax administration regarding the Luxembourg direct and indirect tax treatment of murabahah transactions and sukuk.

i Direct taxation

Murabahah transactions

For the purposes of the following paragraphs, a murabahah transaction is to be understood as an agreement transaction consisting of two consecutive sales of a certain asset whereby, at the first stage, a party (the financier) purchases an asset from a third party upon the request of its counterparty (the purchaser) and then, at the second stage, resells the asset to the purchaser at a marked-up price, payable by the purchaser on a deferred basis.

From a Luxembourg general tax perspective, the capital gain generated at the hands of the Luxembourg financier upon the mere execution of the second sale and purchase agreement between the financier, as seller, and the purchaser, would, in principle, be fully taxable at a current combined rate of 24.94 per cent (corporate income tax, increased by the solidarity surcharge, and municipal business tax for companies established in Luxembourg City) for 2021.

However, Circular LG-A No. 55 issued by the director of the Luxembourg direct tax administration on 12 January 2010 (the Direct Tax Circular) provides for deferred taxation of the capital gain on a straight-line basis over the full payment deferral period under the murabahah agreement (which usually corresponds with the duration of the murabahah agreement), notwithstanding any reimbursements made during this period.

From an economic perspective,46 the Direct Tax Circular compares the capital gain generated in the hands of the Luxembourg financier to the remuneration for giving the purchaser the possibility of deferred payment (i.e., it is treated for Luxembourg tax purposes as ordinary interest income, which would have been earned by the Luxembourg financier under conventional financing). It should be noted that the deferred taxation is available only for remuneration earned by the financier for giving the possibility of deferred payment to the purchaser and not, for example, any intermediation fee that the financier may receive.

The treatment of the capital gain realised by a financier as interest income under the Direct Tax Circular is subject to the following conditions, which must be met by the murabahah transaction:

  1. the murabahah agreement must clearly state that the financier is acquiring the asset for immediate resale to the purchaser (within a maximum of six months);
  2. the murabahah agreement must clearly define the various elements constituting the financier's profit:
    • the remuneration for deferred payment;
    • the intermediation fee; and
    • the exact acquisition price of the asset to be paid by the financier and subsequently by the purchaser;
  3. the murabahah agreement must provide for a clear and explicit acknowledgment and acceptance by all parties of the financier's profit;
  4. the murabahah agreement must explicitly define the financier's profit as being the consideration for the service provided to the purchaser, being the possibility of deferred payment given to the purchaser; and
  5. from an accounting and tax perspective, the financier's profit must be booked in the same way. In other words, the pure profit (i.e., the remuneration for the possibility of deferred payment) must be spread over the deferred payment period stipulated in the murabahah agreement, regardless of the actual dates of repayment.

If the purchaser is a Luxembourg tax resident, any payments remunerating the financier for giving the purchaser the possibility of deferred payment under the murabahah agreement should, in principle, be exempt from Luxembourg withholding tax and should also be deductible for tax purposes, subject to the interest deduction limitation rules that apply depending on the assets held and income received by the purchaser (not applicable to purchasers qualifying as financial undertakings such as, inter alia, UCITS or AIFs),47 and unless they relate to items of income that are exempt in Luxembourg (e.g., foreign real estate) and provided that the above conditions are met.


Pursuant to the Direct Tax Circular, sukuk may be considered a conventional debt instrument (i.e., as a bond (its return, or interest, being dependent on the performance of the underlying asset)). Any profit distributions made under the sukuk to its holders are, in principle, deductible in the hands of the issuer (subject to the interest deduction limitation rules that apply depending on the assets held and income received by the issuer (not applicable to issuers qualifying as financial undertakings such as, inter alia, UCITS or AIFs)) and such distributions are not subject to Luxembourg withholding tax.48

ii Indirect taxation

Registration duties


Depending on the underlying asset of a murabahah agreement, Luxembourg registration duties could be due, in principle, on each sale and purchase of the said asset (e.g., Luxembourg situs real estate).

Pursuant to Circular No. 749 issued by the director of the Luxembourg indirect tax administration on 17 June 2010 (the Indirect Tax Circular), the registration duties payable in Luxembourg on a murabahah agreement concerning real estate located in Luxembourg City are limited to 2.8 per cent under the conditions that:

a both notarial deeds (documenting the purchase and the resale) are registered with the indirect tax authorities at the same time; and

b the financier explicitly declares in the first notarial deed (documenting the purchase) that the real estate asset will be subsequently resold.

The amounts on which registration duties are calculated are limited solely to the acquisition price paid by the financier on the first sale. The profit of the financier, which is considered interest, is thus not subject to registration duties in Luxembourg under the following conditions:

  1. the purchaser must take possession of the real estate asset immediately after the second sale and purchase agreement;
  2. no more than 10 days must separate the first sale and purchase agreement from the second; and
  3. the first sale and purchase agreement must contain a clause stating that the transaction is being carried out as a murabahah agreement, a copy of which must be annexed to the notarial deed relating to the first sale and purchase agreement.

The issue of sukuk should, in principle, not give rise to any registration duties in Luxembourg, provided that the terms and conditions of the sukuk are not physically attached to a public deed or to any other document subject to mandatory registration in Luxembourg. If the proceeds derived from the issue of sukuk are used for instance to purchase Luxembourg situs real estate, registration duties would, in principle, be due with respect to the purchase agreement relating to the real estate properties.

Value added tax

The Indirect Tax Circular states that financiers created for the purpose of a murabahah transaction are treated under Luxembourg value added tax (VAT) law as taxable persons.

iii Taxation of shariah-compliant funds

Shariah-compliant funds structured as UCITS, Part II Funds, SIFs and certain types of RAIFs (SIF-type) are exempt from any Luxembourg income, withholding, capital gains or net wealth tax. They are, however, subject to an annual subscription tax ranging between 0.01 and 0.05 per cent, calculated and payable quarterly on their aggregate net assets as valued at the end of the relevant quarter. Certain exemptions and reductions can apply.

SICARs and certain types of RAIFs (RAIFs carrying out risk capital investments and opting for a special tax regime identical to the regime applicable to SICARs) may be incorporated in the form of a fiscally opaque vehicle or as a tax-transparent vehicle. If set up as tax-opaque vehicles, these are considered fully taxable companies (i.e., subject to corporate income tax, municipal business tax and the solidarity surcharge), but benefit from an exemption on any income derived from transferable securities connected with investments in risk-bearing capital or for cash held for the purpose of a future investment. These types of funds may, however, be subject to the minimum net wealth tax regime.

Further, with respect to VAT, pursuant to Circular No. 723 of 29 December 2006, undertakings for collective investment are, in principle, considered VAT-taxable persons. Thus, Luxembourg VAT may be applicable under the reverse charge mechanism whereby a fund domiciled in Luxembourg receives taxable services from suppliers located in other EU Member States, unless a specific VAT exemption may be secured (such as fees on the negotiation of securities, for example). A fund would, in principle, have no right to deduct input VAT as it should normally carry out activities that are exempt from VAT only.

iv Taxation of securitisation undertakings

Securitisation undertakings subject to the Securitisation Act benefit from a favourable tax regime. If set up as a company, they are, in principle, fully taxable companies, subject to corporation tax at a current combined rate of 24.94 per cent (corporate income tax, increased by the solidarity surcharge, and municipal business tax for securitisation undertakings established in Luxembourg City) in 2021. However, the Securitisation Act states that the obligations assumed by securitisation undertakings towards their investors (including shareholders) and any creditors are to be considered tax-deductible expenses. In other words, securitisation undertakings should be able to deduct any payments due or made to any investors, or creditors, from their taxable profits, subject to the interest deduction limitation rules that apply depending on the assets held and income received by the securitisation undertaking.

Securitisation undertakings are exempt from net wealth tax, except for the minimum net wealth tax.

Further, there is no Luxembourg withholding tax on payments of interest or on profit distributions made by a securitisation undertaking to its investors.49

With respect to VAT, securitisation undertakings are considered VAT-taxable persons if they are deemed to be carrying out an economic activity. If a securitisation undertaking qualifies as a VAT-taxable person, Luxembourg VAT may be applicable under the reverse charge mechanism if a securitisation undertaking domiciled in Luxembourg receives taxable services from suppliers located in other EU Member States. A securitisation undertaking would, in principle, have no right to deduct input VAT to the extent it solely carries out activities that are exempt from VAT.


In Luxembourg, there is no special insolvency regime with respect to shariah-compliant products.

In insolvency or restructuring scenarios, holders of sukuk should, in principle, be treated in the same way as holders of conventional bonds. This is in line with the position of the Luxembourg direct tax administration, expressed in the Direct Tax Circular, according to which there should be no difference in the tax treatment of sukuk and conventional bonds.50

In this respect, it is important to highlight the advantages of using Luxembourg securitisation undertakings subject to the Securitisation Act, which frequently act as issuers of sukuk. As discussed above, such securitisation undertakings are bankruptcy-remote and their investors benefit from a high level of protection and legal certainty embedded in the law. Thanks to provisions such as the compartmentalisation of rights and claims relating to different transactions and the limitation of investors' recourse to the assets available in the compartment in which they have invested, the risk of the entire vehicle becoming insolvent is very small.

Judicial framework

Luxembourg does not have a specific court or tribunal for Islamic finance disputes. Luxembourg conventional courts will hear claims relating to transactions governed by Luxembourg law over which they have jurisdiction, including those involving aspects of shariah law. In the case of a conflict between Luxembourg laws and the principles of shariah law, Luxembourg laws will prevail.51

Any conflicting matter in relation to regulated funds or their Luxembourg-regulated manager may potentially be dealt with by the CSSF following the out-of-court resolution of the complaints procedure. The CSSF's out-of-court resolution of disputes procedure is provided on a voluntary basis. It aims to simplify the resolution of disputes without the need for legal proceedings. Opening an out-of-court complaint resolution procedure with the CSSF is subject to the condition that the complaint has been dealt with by the management of the relevant professional beforehand. In this respect, the complaint must have been first submitted in writing to the individual responsible for complaint handling.52 If the CSSF does not manage to resolve the issue, the parties are free to bring their claim before the relevant tribunal.

To the best of our knowledge, there has been no Luxembourg court case that would have impacted the treatment of Islamic finance products or structures implemented under Luxembourg law or using a Luxembourg vehicle.


The CSSF has signed memoranda of understanding (MoU) with the supervisory authorities of a number of major markets in the area of Islamic finance, such as Bahrain, Malaysia, Oman, Qatar and the United Arab Emirates (including Dubai and Abu Dhabi).53 Following the European Securities and Markets Authority's approval of cooperation agreements between EU securities regulators and their international counterparts, the CSSF has also signed MoU with supervisory authorities of third countries, such as Dubai, Egypt and Malaysia,54 meeting the requirements of the AIFMD in view of developing cooperation agreements. Luxembourg has also signed double taxation treaties with major actors in Islamic finance, such as Malaysia, Qatar and Saudi Arabia,55 and other treaties are currently under negotiation with Kuwait and Oman.56 These developments highlight the growing interest in Islamic finance and are in line with the proactive approach adopted by the government aimed at making Luxembourg an attractive place for Islamic financial players.57 Although shariah-compliant products and structures have become a regular feature on the list of services offered by Luxembourg's diverse and dynamic financial sector, there is still potential for growth and numerous opportunities are waiting to be explored.
