Two out of every three companies on the Luxembourg Business Registers are SARLs. That figure alone tells you something about the structure’s versatility: it is used by solo freelancers running a consultancy, by mid-sized family businesses managing regional operations, and by multinational groups incorporating local subsidiaries. The Société à Responsabilité Limitée sits at the sweet spot between protection, flexibility, and cost.
At Financial Services Luxembourg, we have incorporated hundreds of SARLs for clients ranging from first-time entrepreneurs to private equity sponsors setting up Luxembourg SPVs. What follows is a practical guide to SARL formation and private limited company requirements drawn from that hands-on experience.
What Is a Luxembourg SARL and Why Is It So Popular?
A SARL is a private limited liability company governed by the Law of 10 August 1915 on commercial companies (as amended). Shareholders are liable only up to the amount of their capital contributions, which creates a clean separation between personal assets and business risk. The structure accepts between 1 and 100 shareholders (natural or legal persons, resident or non-resident), requires a minimum share capital of €12,000 fully paid up at incorporation, and is managed by one or more gérants (managers) who may or may not be shareholders themselves.
Shares in a SARL are not freely transferable. Any transfer to a third party requires the approval of a majority of shareholders representing at least 75 % of the share capital, unless the articles of association set a different threshold. For founders who want to keep control of their cap table and prevent unwanted entries, this restriction is a feature, not a bug. It is also one of the main reasons why international groups use the SARL for subsidiaries: the parent company retains full control over who can become a shareholder.
“A SARL gives you something an SA does not: built-in cap-table protection. Shares cannot be sold to an outsider without shareholder consent. For a family business, a joint venture, or a PE-backed subsidiary, that lock-in mechanism is worth more than any governance clause you could draft into an SA’s articles.”

Step-by-Step: How to Form a SARL in Luxembourg
1. Define the Project and Check Manager Eligibility
Before any paperwork begins, determine the business activity, target markets, number of shareholders, and capitalisation plan. If the SARL will conduct commercial, industrial, or craft activities, the appointed manager must satisfy the professional qualification and integrity requirements set by the Direction Générale aux Classes Moyennes. A manager who cannot demonstrate the right credentials will see the business permit application rejected, regardless of how clean the rest of the file is.
2. Reserve a Company Name
Submit a name availability request electronically to the Luxembourg Business Registers (LBR). Prepare two or three alternatives. The name must not be identical or confusingly similar to any existing entity on the register.
3. Open a Bank Account and Deposit €12,000
Open an account in the name of the company in formation at a Luxembourg bank and deposit the full €12,000. The bank issues a blocking certificate (attestation de blocage) that the notary will require at the signing of the deed. Under current anti-money-laundering rules, banks run a full KYC review before accepting the deposit: certified passport copies, proof of address, a source-of-funds narrative, and a business plan are the minimum.
“The bank account is where most SARL formations slow down or stall completely. Banks do not care that your notary is ready or that your business permit is pre-approved. If your KYC file has a gap, they will send it back and you lose two weeks. I always build the bank dossier before we even approach a notary. Passport copies, address proof, source of funds, a business plan with twelve-month projections, a governance chart. When that file is airtight, the account opens in five to ten working days. When it is not, you wait.”

4. Draft and Sign the Articles of Association Before a Notary
The notary drafts the articles of association (statuts), which set out the company name, registered office, corporate purpose, duration, share capital, number and value of shares, and the rules governing share transfers and management. Founders sign the deed in person or through a power of attorney. The notary then files the deed for publication in the Recueil Électronique des Sociétés et Associations (RESA) and registers the company with the Trade and Companies Register (RCS). Once published, the SARL gains legal personality.
5. Obtain the Business Establishment Authorisation
Apply for the autorisation d’établissement through MyGuichet.lu. The Ministry of Economy typically processes applications in five to fifteen working days. Without this permit, you cannot legally begin commercial activities, even if the company is fully registered with the RCS.
6. Register for Tax, VAT, and Social Security
Register with the Administration des Contributions Directes (ACD) for corporate income tax, with the Administration de l’Enregistrement, des Domaines et de la TVA (AED) for VAT, and with the Centre Commun de la Sécurité Sociale (CCSS) if the company will employ staff. File the beneficial ownership declaration with the RBE within one month.
How Much Does It Cost to Form a SARL in Luxembourg?
Beyond the €12,000 share capital (which remains in the company as working capital, not a fee), you should expect notary fees of approximately €1,500, RCS filing and RESA publication fees of around €200 to €300, the autorisation d’établissement application fee of €50, and professional advisory fees for preparing the articles of association, handling KYC documentation, and managing administrative filings. Domiciliation costs vary depending on whether you need a full office or just a registered address. All told, formation costs for a professionally managed SARL typically fall between €3,000 and €6,000, excluding the share capital itself.
Tax Rules for a Luxembourg SARL
Since 1 January 2025, the corporate income tax rate stands at 14 % for taxable income up to €175,000 and 16 % for income above €200,000, with a smoothing mechanism in between. Add the 7 % solidarity surcharge on CIT and the municipal business tax (6.75 % in Luxembourg City), and the combined effective rate comes to approximately 23.87 %. Outside the capital, the rate can be slightly lower because municipal tax rates differ by commune.
VAT registration is mandatory once the company carries out economic activities. The standard rate is 17 %, with reduced rates of 14 %, 8 %, and 3 % applying to certain categories. If annual turnover stays below €35,000, the VAT franchise scheme may apply, reducing administrative burden. Net wealth tax is calculated annually on the balance sheet; the 2025 simplification has removed the old distinction between financial and non-financial assets for determining the minimum NWT.
“Founders fixate on the 23.87 % headline rate, but the real question is what stays in the company after all deductions. Luxembourg allows loss carry-forward with no time limit, deductions for arm’s-length management fees and intragroup interest, and a participation exemption that can make qualifying dividend income tax-free. The effective burden on a well-structured SARL can be substantially lower than the headline suggests. That is where proper planning from day one pays for itself many times over.”

Upcoming Reform: Deferred Capital Payment for SARLs
On 16 December 2025, the Luxembourg Government introduced a draft bill proposing to amend the Law of 10 August 1915. If adopted, shareholders would still need to subscribe the full €12,000 at incorporation, but could defer the actual cash payment for up to 12 months. The reform targets a practical bottleneck: the time it takes to open a bank account and deposit funds before the notary can pass the deed. Contributions in kind would still need to be paid in full at incorporation, and any amount above the €12,000 minimum would also need to be settled upfront.
As of early 2026, the bill is under review by the Chamber of Deputies and the Council of State. If you are planning a SARL formation in the coming months, it is worth monitoring this development closely, as it could shorten the incorporation timeline significantly.
Shareholder Rights, Management Structure, and Corporate Governance
A SARL is managed by one or more gérants appointed in the articles of association or by a subsequent shareholder resolution. Managers handle day-to-day operations, represent the company towards third parties, and are personally responsible for management faults. Shareholders retain authority over major decisions: amendments to the articles of association, approval of annual accounts, distribution of dividends, and appointment or removal of managers. Resolutions generally require a majority of shareholders holding at least 50 % of the share capital, though certain decisions (like amending the articles) require a qualified majority of 75 %.
If the SARL exceeds two of the three following thresholds, it must appoint a statutory auditor (réviseur d’entreprises agréé): balance sheet total above €4.4 million, net turnover above €8.8 million, or average headcount above 50 employees. Below those thresholds, the shareholders may appoint a commissaire aux comptes (internal auditor), which is less onerous but still provides a layer of oversight.
“I tell every client: draft your articles of association as if the shareholders will disagree one day, because eventually they will. Define clearly how profits are distributed, how managers are replaced, what happens if a shareholder wants to exit, and what majority thresholds apply to each type of decision. A well-drafted SARL statute prevents ninety percent of the disputes I see in my practice.”
— Mickaël LOC, Managing Director, Financial Services Luxembourg
Ongoing Compliance After Your SARL Is Up and Running
Annual accounts must be prepared under LuxGAAP and filed with the LBR via the eCDF platform. Corporate income tax returns go to the ACD. VAT declarations are submitted monthly or quarterly depending on turnover. If the SARL employs staff, payroll declarations to the CCSS and compliance with Inspection du Travail et des Mines (ITM) rules must be handled. The RBE must be updated whenever the beneficial ownership structure changes.
At Financial Services, we manage all of these recurring tasks for our clients. Every company is assigned a named advisor who knows the file, tracks deadlines, and prepares filings so founders can focus on running the business.
