Setting up a SARL in Luxembourg: steps, capital and procedures

In short. Setting up a SARL (private limited liability company) in Luxembourg requires share capital of 12,000 €, articles of association before a notary, registration with the Trade and Companies Register (RCS) and, before you start trading, a business permit. In practice, allow 4 to 8 weeks, the main delay being the opening of the bank account that receives the capital. Worth knowing: a reform voted in April 2026 allows, for cash contributions, deferring the paying-up of that capital, which changes your starting cash position.

The SARL accounts for the vast majority of company formations in Luxembourg. It protects your personal assets, does not demand the heavy capital of an SA, and suits the freelancer going formal as much as the SME setting up. What remains is to know the real path, the one that plays out between the bank, the notary and the RCS. Here it is, without the brochure version.

Why is the SARL the most chosen form?

The SARL is the limited liability company: your losses are, in principle, capped at your contribution. If the business turns sour, creditors do not reach your house or personal accounts, barring management fault. That is the first reason for its popularity.

Three concrete advantages follow. The required capital (12,000 €) stays accessible, where a public limited company (SA) asks for 30,000 €. Governance is flexible: one or more managers, shareholder decisions without the formalism of a board. And the SARL can hold from 1 to 100 shareholders, natural or legal persons, which opens the door to family structures, holdings and the entry of investors.

If your starting budget is very tight and you are a natural person, a variant exists, the simplified SARL (SARL-S), with capital starting at 1 €. It follows specific rules, detailed in our guide to the SARL-S in Luxembourg; for most projects aiming at banking and commercial credibility, the classic SARL remains the reference.

What capital you need, and the rule changes in 2026

The minimum share capital of a SARL is 12,000 €, fully subscribed at incorporation. Until recently, it also had to be fully paid up before signing, into a blocked account in the name of the company in formation. It was this upfront payment that forced you to open a bank account before the company even existed, and that stretched the timelines.

That is precisely the lock a reform has loosened. A bill (no. 8669), adopted by the Chamber of Deputies on 28 April 2026, introduces the option to pay up the capital on a deferred basis, in whole or in part, within a period of up to 12 months, where contributions are in cash. The capital stays fully subscribed from the start, but no longer has to be paid in immediately. In practice, you can incorporate without waiting for the account to open or mobilising the 12,000 € on day one.

At the time of writing (June 2026), confirm the exact entry-into-force date of the text when you launch your project, along with the transparency obligations attached to it (the list of shareholders who have not yet paid up their shares is published after the balance sheet). This is exactly the kind of point where a dated figure leads to a poor decision: you confirm the rule in force on the day.

Not sure whether deferred paying-up applies to you? Depending on the nature of your contributions and the calendar, this trade-off changes your launch cash position. Advena reviews it with you before any step. Book a 30-minute call.

The formation steps, in order

A SARL formation follows a fairly stable order. Knowing it avoids stalling on one step because another was not prepared.

1. Check the company name. You verify with the RCS (Luxembourg Business Registers) that the chosen name is available and distinct from any existing company. It is quick, but blocking: no validated name, no articles.
2. Open the account and deposit the capital. The capital is paid into an account in the name of the company in formation, which issues a blocking certificate. The account unblocks after registration. With deferred paying-up (see above), this step can be rearranged, but opening the account remains, in practice, the main bottleneck (two to six weeks depending on the bank).
3. Sign the articles before a notary. The SARL is incorporated by notarial deed. All shareholders sign, or grant a power of attorney. The notary checks the contributions, drafts the deed and handles the publication formalities.
4. Register with the RCS. The company is entered in the Trade and Companies Register, and the deed is published in the Electronic Compendium of Companies and Associations (RESA). It is registration that gives the company legal birth.
5. Obtain the business permit. For a commercial, craft, industrial activity or certain liberal professions, you need a permit issued by the Ministry of the Economy, before trading begins. In practice, it is often finalised around registration; trading without it is prohibited and penalised.
6. Register for VAT and social security. You register the company with the Registration Duties, Estates and VAT Authority (AED), and affiliate the manager(s) with the Joint Social Security Centre (CCSS).

The recurring point of attention: these steps are not strictly sequential. You prepare the business permit in parallel with opening the account, because it is the permit, and the bank, that dictate the real calendar. A file moving on a single front mechanically falls behind.

How much does it cost to set up a SARL?

Beyond the capital (which is not an expense but a contribution that stays with the company), formation entails fees. They vary with the notary, the complexity of the articles and the support chosen, but orders of magnitude can be given.

As an indicative budget excluding capital, the total of notary, registry fees and support often sits between 2,200 € and 4,400 € for a classic SARL with standard articles. Tailored articles, several shareholders or contributions in kind push the figure up. These amounts change and must be confirmed when you launch; they give the scale, not the quote.

Setting up your SARL as a cross-border worker or non-resident

It is a frequent question in the Greater Region: can you form a Luxembourg company without living in Luxembourg? Yes. The nationality and residence of shareholders are no obstacle to incorporating a SARL. A Belgian, French or German resident can be a shareholder and manager of a Luxembourg company.

Two points deserve real attention, though. First, the business permit rests on the professional qualification and good standing of the manager, not on their place of residence: it is the director's profile that counts. Second, the company must have real substance in Luxembourg (an effective seat, an activity connected to it): a shell run entirely from abroad exposes you to tax reclassification. Forming the company is simple; giving it a solid base takes method. That is where local support avoids costly mistakes.

After formation: what no one tells you

Registration is not the end of the path, it is the start of the obligations. A SARL keeps accounts compliant with the standardised chart (PCN 2020), files its annual accounts with the RCS within the legal deadlines, and handles its VAT on a frequency that depends on its turnover. Many founders discover these constraints after the fact, for not having connected formation to management.

That is exactly the bridge Advena builds under one roof: the legal structure, Luxembourg accounting and the management tool that holds them together. Instead of forming the company on one side and looking for an accountant on the other, you set the form, the chart of accounts and the digitalisation from the start. If you intend to run your business in an integrated tool, this is the moment to look at Luxembourg accounting properly configured in Odoo, from the very first entry.

Frequently asked questions

What capital do you need to set up a SARL in Luxembourg?

12,000 €, fully subscribed at incorporation. Since the reform adopted in April 2026, this capital can, for cash contributions, be paid up on a deferred basis within up to 12 months. Confirm the entry-into-force date when you launch your project.

How long does it take to set up a SARL?

In practice, 4 to 8 weeks. The main delay is opening the bank account that receives the capital, which can take two to six weeks depending on the bank.

Do you need a notary to set up a SARL?

Yes. The classic SARL is incorporated by notarial deed. Only the simplified variant (SARL-S), reserved for natural persons, can be created by private deed, without a notary.

Can a cross-border worker set up a company in Luxembourg?

Yes. Neither residence nor nationality blocks formation. The manager must, however, meet the qualification and good-standing conditions of the business permit, and the company must have real substance in Luxembourg.

What is the difference between a SARL and a SARL-S?

The SARL-S is a simplified SARL, reserved for natural persons, with capital from 1 € to under 12,000 € and formation without a notary. The classic SARL requires 12,000 € and a notarial deed, but accepts legal persons.

In practice: where to start

Before booking a notary, clarify three things: the nature of your contributions (cash or in kind, since it governs deferred paying-up), the manager's profile (who will carry the business permit), and the exact activity (which determines the permit and the VAT regime). Those three answers unlock the rest. Forming a company is a formality; forming the right structure, well connected to its accounting, is a management decision, and it is that decision that pays off or costs over time.
