In this article, we’ll explore the different options available to you and guide you through this important choice.

Main Legal Structures in Luxembourg: A Range of Possibilities

Luxembourg offers a variety of legal structures suited to different types of businesses and commercial objectives. Here’s an overview of the main options:

1. Private Limited Liability Company (SARL)

The SARL is one of the most popular legal forms in Luxembourg, particularly suitable for small and medium-sized enterprises. It offers considerable flexibility and limited liability for partners. The main characteristics of the SARL are:

• Minimum share capital: €12,000
• Number of partners: between 1 and 100
• Partners’ liability limited to their contributions
• Management by one or more managers

2. Public Limited Company (SA)

The SA is generally chosen by large companies or those considering a stock market listing. It offers a more formal structure and is often perceived as more prestigious. Its main characteristics are:

• Minimum share capital: €30,000
• Number of shareholders: no limit
• Shareholders’ liability limited to their contributions
• Management by a board of directors

3. Simplified Limited Liability Company (SARL-S)

Introduced in 2016, the SARL-S is a streamlined version of the SARL, designed to facilitate entrepreneurship. Its particular features are:

• Minimum share capital: €1
• Reserved for individuals
• Limited to 5 SARL-S per person
• Requirement to set aside 5% of annual profits as reserves

4. Partnership Limited by Shares (SCA)

The SCA combines characteristics of partnerships and capital companies. It’s particularly interesting for family businesses or investment structures. Its specific features are:

• Two types of partners: general partners (unlimited liability) and limited partners (limited liability)
• Minimum share capital: €30,000
• Flexibility in governance

Sole Proprietorship or Company: Which Path to Choose for Your Luxembourg Adventure?

The decision to opt for a sole proprietorship or a company is fundamental and depends on several factors. Let’s examine the advantages and disadvantages of each option in the Luxembourg context.

Sole Proprietorship: Simplicity and Flexibility

The sole proprietorship, also known as “commerçant en nom personnel” in Luxembourg, is the simplest form to start a business. It’s particularly suitable for individual entrepreneurs, craftspeople, and liberal professions. Its main advantages are:

• Simplified creation formalities
• Reduced startup costs
• Management flexibility
• No minimum capital required

However, the sole proprietorship also has significant disadvantages:

• Unlimited liability of the entrepreneur on personal assets
• Difficulty raising funds
• Less professional image for some clients or partners

The Company: Enhanced Protection and Credibility

Creating a company in Luxembourg offers numerous advantages, particularly for businesses with growth ambitions or requiring a more formal structure. The main advantages are:

• Limited liability of partners or shareholders
• Better credibility with business and financial partners
• Ability to raise funds more easily
• Potential tax optimization
• Ease of business transfer

However, creating a company also involves certain constraints:

• More complex creation formalities
• Higher creation and operating costs
• Stricter accounting and tax obligations
• Requirement for minimum share capital (except for SARL-S)

The Luxembourg SARL: The Preferred Choice of Entrepreneurs

Among the different legal forms available in Luxembourg, the Private Limited Liability Company (SARL) stands out as the preferred choice for many entrepreneurs. This popularity is explained by several factors that make it a particularly attractive option.

Flexibility and Control

The SARL offers an excellent balance between operational flexibility and legal protection. Partners have direct control over business management, with the possibility to appoint one or more managers who can be partners or third parties. This structure allows for quick and effective decision-making, essential in Luxembourg’s dynamic business environment.

Protection of Personal Assets

One of the major advantages of the SARL is the limitation of partners’ liability to their contributions. This means that partners’ personal assets are protected in case of business financial difficulties, a crucial aspect for entrepreneurs wanting to minimize personal risks.

Accessible Share Capital

With a minimum share capital of €12,000, the SARL is accessible to a wide range of entrepreneurs. This amount, while not negligible, remains reasonable compared to other legal forms like the SA, which requires a minimum capital of €30,000.

Tax Optimization

The SARL benefits from an advantageous tax regime in Luxembourg. It’s subject to corporate tax, with rates that are competitive compared to other European countries. Additionally, Luxembourg offers various tax benefits for holdings and investment companies, which can be particularly interesting for entrepreneurs with international ambitions.

Credibility and Professional Image

Opting for a SARL in Luxembourg conveys an image of seriousness and professionalism. This legal form is well-known and respected in the business world, which can facilitate relationships with clients, suppliers, and financial institutions.

The Luxembourg SA: The Choice Option for Big Ambitions

The Public Limited Company (SA) represents the upper tier of business structures in Luxembourg. It’s particularly suitable for companies with significant growth ambitions or considering a stock market listing. Let’s examine the characteristics that make the SA an attractive option for some entrepreneurs.

Prestige and Credibility

The SA is perceived as the most prestigious legal form in Luxembourg. It inspires confidence in investors, business partners, and financial institutions. This enhanced credibility can be a major asset for companies seeking to establish themselves on the international stage or attract significant investments.

Formal Governance Structure

The SA is characterized by a more formal governance structure, with a board of directors and the possibility to appoint directors. This organization can be an advantage for companies requiring more complex management or wanting to clearly separate ownership from management.

Ease of Capital Raising

One of the main strengths of the SA is its ability to raise funds. The possibility to issue shares and bonds makes this legal form particularly attractive for companies needing significant financing for their growth.

Stock Market Listing

For companies considering a stock market listing, the SA is the required legal structure in Luxembourg. This characteristic makes it the natural choice for ambitious startups or companies aiming for rapid expansion.

Flexibility in Transfer

The SA offers great flexibility in transferring shares. Shares can be easily transferred, which can be a significant advantage for family businesses or those planning ownership changes in the long term.

The SARL-S: Ideal Launchpad for Luxembourg Startups

Introduced in 2016, the Simplified Limited Liability Company (SARL-S) has quickly gained popularity among Luxembourg entrepreneurs. This innovative legal form aims to facilitate business creation by reducing entry barriers. Let’s examine why the SARL-S has become the preferred choice of many startups in the Grand Duchy.

Symbolic Minimum Capital

The major advantage of the SARL-S is its minimum share capital set at €1. This characteristic significantly reduces the initial cost of creating a business, allowing entrepreneurs to start their activity with minimal investment. However, it’s important to note that the SARL-S must set aside 5% of its annual profits as reserves until reaching the threshold of €12,000, equivalent to the minimum capital of a classic SARL.

Simplified Creation Procedure

The creation of a SARL-S benefits from a streamlined procedure compared to other legal forms. Administrative formalities are reduced, and it’s possible to create the company without going through a notary, which speeds up the process and reduces incorporation costs.

Flexibility and Evolution

The SARL-S offers great flexibility to entrepreneurs. It can evolve into a classic SARL once the share capital reaches €12,000, allowing for natural business growth. This characteristic makes it an excellent launchpad for startups anticipating rapid growth.

Risk Limitation

As with a classic SARL, the liability of SARL-S partners is limited to their contributions. This protection of personal assets is a major advantage for entrepreneurs wanting to launch while minimizing personal financial risks.

Restrictions and Considerations

It’s important to note that the SARL-S involves certain restrictions. It’s reserved for individuals and each person can only be a partner in a maximum of five SARL-S. Additionally, the SARL-S activity must fall under commerce, crafts, industry, or certain liberal professions.

Key Factors for Choosing the Right Legal Structure in Luxembourg

Choosing the legal structure for your business in Luxembourg is a crucial decision that will have long-term implications for your activity. Here are the key factors to consider for making the right choice:

1. Objectives and Long-Term Vision

Your choice must align with your long-term ambitions. If you’re considering rapid growth or international expansion, an SA or SARL might be more appropriate. For a more modest project or niche activity, a SARL-S or sole proprietorship might suffice.

2. Available Capital and Financing Needs

The capital you have available and your future financing needs are crucial elements. If you have limited resources initially but anticipate significant financing needs, a SARL-S evolving into a SARL or SA could be a good strategy.

3. Complexity of Governance Structure

Think about the governance structure you want. An SA offers a more formal structure with a board of directors, while a SARL allows for more direct and flexible management.

4. Protection of Personal Assets

Liability limitation is a crucial factor. Corporate forms (SARL, SA, SARL-S) offer better protection of personal assets than sole proprietorships.

5. Taxation

Tax implications vary according to the chosen legal structure. In Luxembourg, companies generally benefit from an advantageous tax regime, but it’s essential to evaluate the specifics of each legal form based on your situation.

6. Flexibility and Future Evolution

Consider how easily you’ll be able to evolve your legal structure in the future. Some forms, like the SARL-S, offer greater flexibility to evolve toward other structures.

7. Image and Credibility

The chosen legal structure can influence how your business is perceived by clients, partners, and investors. An SA may be perceived as more prestigious, while a SARL or SARL-S may be seen as more dynamic and entrepreneurial.

8. Business Sector

Certain business sectors may have specific requirements regarding legal form. Ensure the chosen structure is compatible with your field of activity.
