The SARL is a common Luxembourg company form for an operating business, a subsidiary or a closely held venture. It has its own legal personality and its shareholders are liable for company debts up to their contributions.
That protection does not cover a personal guarantee. It also does not release a manager from liability for personal misconduct. The SARL separates the company’s assets from those of its shareholders without cancelling commitments made outside that protection.
The SARL framework
An SARL may have between one and one hundred shareholders. They may be natural persons or legal entities. The company can therefore be owned by one entrepreneur, a family, another company or a limited group of investors.
The company must have a Luxembourg registered office and a corporate object that describes its activity. The legal form does not itself authorise a regulated business. A business permit or sector licence may still be required.
The consolidated Companies Law sets the current rules on shareholders, management, capital and publication.
The EUR 12,000 capital
The minimum share capital is EUR 12,000. It must be fully subscribed when the company is incorporated. The shareholders therefore commit to the whole amount in the deed.
The Law of 18 May 2026, in force since 2 June 2026, allows payment of the minimum cash capital to be deferred for twelve months. The articles must state when the funds will be called or how that call will be decided.
This option applies only to the minimum capital subscribed in cash at incorporation. Contributions in kind, share premium and capital above EUR 12,000 remain paid or contributed when the deed is executed.
Deferral does not remove the capital requirement. Each shareholder remains liable for the unpaid amount on that shareholder’s subscribed shares. After each balance sheet, the filing identifies shareholders who have not paid in full and the amount still outstanding.
Shareholders, shares and management
SARL shares are registered. A transfer to a third party requires approval from shareholders representing three quarters of the capital. The articles may reduce that threshold, but not below half of the capital.
This approval rule gives existing shareholders control over the arrival of a new investor. It differs from the more transferable shares of an SA.
One or more managers direct the company. A manager may be a shareholder or a third party, and may be a natural person or legal entity. The articles and appointment resolutions define signature powers and any joint representation rules.
The classic SARL and the SARL-S
The SARL-S serves a narrower purpose. It permits lower capital and may be incorporated by private deed. In return, only natural persons may be shareholders or managers, and its activities are restricted by its statutory regime.
| Criterion | Classic SARL | SARL-S |
|---|---|---|
| Capital | EUR 12,000 minimum | EUR 1 to EUR 12,000 |
| Shareholders | Natural persons or legal entities | Natural persons only |
| Manager | Natural person or legal entity | Natural person only |
| Incorporation | Notarial deed | Private deed permitted |
| Activity | Broad, subject to required permits | Limited by its specific regime |
Capital is not the only deciding factor. A subsidiary, a company owned by another company or a project expected to admit a legal-entity shareholder requires the classic SARL.
Incorporation and registrations
The founders first settle the points that shape the articles. These include the activity, registered office, capital, shareholders, management, signature powers and financial year.
A classic SARL is incorporated by notarial deed. The official guidance on incorporation documents explains the required content and publication process.
After signature, the deed is filed with the RCS and published in the RESA. Beneficial owners are declared to the RBE. The business permit, VAT identification, social-security registrations and bank account are added when the activity or the company’s situation requires them.
When cash payment is deferred, the notary still verifies that the capital is fully subscribed and records the amount paid at incorporation. Opening and operating the account remains a separate bank process.
Tax and accounting
An SARL falls within the ordinary tax regime for capital companies. Its profit may be subject to corporate income tax and municipal business tax. Its net assets may also enter the net wealth tax calculation.
Rates and thresholds can change. The Luxembourg tax overview therefore explains them separately instead of repeating a full tax table in a company-law guide.
An SARL used as a SOPARFI remains a fully taxable company. Qualifying holdings may benefit from the participation exemption when all conditions are met.
Accounting starts when the company is formed. It records subscribed capital, any unpaid portion, initial expenses, contracts and the first transactions.
Annual obligations
Each financial year follows a recurring cycle. The accounts are closed, annual accounts are prepared and the shareholders approve them. The company then files them with the RCS.
The official annual-accounts procedure provides for approval within six months after the financial year end and filing within one month after approval. The annual accounts filing guide explains how this produces a seven-month outer limit for a legal entity.
The company also submits tax returns and, where relevant, VAT returns. An employer adds payroll and social-security declarations to this calendar.
Conclusion
The Luxembourg SARL combines limited liability, a minimum capital of EUR 12,000 and control over the admission of new shareholders. Since June 2026, payment of the minimum cash capital may be deferred for twelve months when the articles provide for it.
The choice between a classic SARL and an SARL-S depends mainly on ownership, management and activity. Incorporation is the start of a recurring corporate, accounting and tax cycle, not the end of the formation process.

Frequently Asked Questions
What is the minimum capital of a Luxembourg SARL?
The minimum capital is EUR 12,000. It must be fully subscribed at incorporation. Payment of cash contributions may be deferred for twelve months if the articles organise this option.
Can one person form an SARL?
Yes. A single natural person or legal entity may hold all the shares. Its written decisions then replace shareholder meetings.
Does an SARL require a notarial deed?
Yes. A classic SARL is incorporated before a notary. The simplified SARL-S may use a private deed within the limits of its own regime.
Can a non-resident manage a Luxembourg SARL?
Yes. No general rule requires the manager to live in Luxembourg. The company's effective management, business permit and tax residence must still match the facts.
