The SARL-S (société à responsabilité limitée simplifiée) is Luxembourg’s low-cost version of the private limited company. Because it can be set up with very little capital, people often ask whether they can buy one ready-made.
You can, but the SARL-S comes with ownership rules that the standard S.à r.l. does not have. Before you buy a shelf SARL-S, check that you are allowed to own it. If you are not, you will want a different company form.
This article covers those rules. For the basics of every company type, see our guide to company types in Luxembourg. For how the takeover of a standard shelf company works, see our article on the shelf S.à r.l.
What is a shelf SARL-S?
A shelf SARL-S is a SARL-S that has already been incorporated and registered with the Luxembourg Trade and Companies Register (RCS), but has not traded. As with any shelf company, you buy its shares and take over its management. We can supply shelf SARL-S companies as well as standard shelf S.à r.l. companies.
The SARL-S has the same limited liability as a standard S.à r.l. Its share capital can start at €1, and it can be formed by private deed rather than a notarial deed.
Who can own a SARL-S
This is where the SARL-S differs most from the standard S.à r.l.
- Only natural persons can be shareholders. A company can never hold shares in a SARL-S.
- Between 1 and 100 shareholders.
- One SARL-S per person. A natural person can be a shareholder in only one SARL-S at a time. The exception is shares that pass to them after another shareholder’s death. The same person can still hold shares in companies of other legal forms.
- Managers must be natural persons. A corporate manager is not possible.
These rules decide who can buy. A holding company, a group entity or an investor who wants to hold through a corporate vehicle cannot own a SARL-S. If that describes you, a standard S.à r.l. is the right form.
Transfer approval
SARL-S shares are not freely transferable. During a shareholder’s lifetime, voting shares can only go to someone who is not already a shareholder with the approval of shareholders representing at least 75% of the share capital. The articles can lower this threshold, but not below 50%. The transfer is recorded in a private or notarial deed.
For a shelf company this is normally straightforward, because the seller is the sole shareholder. As with a standard S.à r.l., the rule matters again when you later bring in a partner. Set the threshold you want in the articles.
Taking over a shelf SARL-S: the steps
- Check you qualify. You must be a natural person and not already a shareholder in another SARL-S.
- Provide your documents. Identity and beneficial owner details. See the documents needed.
- Sign the share transfer. It is recorded in a private or notarial deed, with the approval recorded as required.
- Appoint your managers. They must be natural persons. The change is filed with the RCS.
- Update the registers. The shareholder register changes, and the new ownership is filed with the beneficial owner register (RBE) within one month.
- Change the name or address if you wish. Remember that the company name must appear together with the wording “SARL-S” on its legal documents.
- Check whether you need a business licence. Forming a SARL-S requires a business licence from the Ministry of the Economy. If your activity is regulated, confirm the position before you complete.
- Arrange your bank account and accounting. See bank accounts.
Once the documents are complete, the share transfer itself is usually a matter of days. The bank account and any licence follow their own timelines.
Capital: what to check
A SARL-S incorporated after 2 June 2026 can use the deferred payment regime. Legal commentary on the 2026 law indicates that for a SARL-S, deferral can cover the whole capital subscribed in cash, within a 12-month limit. If you buy a shelf SARL-S incorporated after that date, you need to know how much capital is still unpaid, when it is due and who bears it. Our due diligence checklist explains how to verify this.
A very small capital also affects how banks and counterparties see the company. We cover this in our company types guide.
The legal reserve
A SARL-S must build up a legal reserve. Each year, 5% of its profits is set aside in the reserve, until it reaches €12,000, the minimum share capital of a standard S.à r.l. Until then, that part of the profit cannot be paid out as dividends.
This is a cost of the low-capital model that is easy to miss. A shelf SARL-S that has already been trading or has accumulated profits will show a reserve in its accounts, so check where it stands before you complete.
The growth trap
A SARL-S is meant for small projects. If it exceeds 100 shareholders, or its share capital goes above the SARL-S limit, it must change its legal form within the period the law allows, and the shareholders decide this at a meeting. In practice, that means converting to a standard S.à r.l.
The same applies if you want a corporate shareholder. A company cannot hold a SARL-S, so the structure has to change before one can come in.
SARL-S or standard S.à r.l.?
| Question | SARL-S | Standard S.à r.l. |
|---|---|---|
| Who can be a shareholder? | Natural persons only | Individuals or companies |
| How many can one person own? | One SARL-S at a time | No such limit |
| Who can be a manager? | Natural persons only | Natural persons or companies, as the articles allow |
| Holding or group structure? | Not possible | Yes |
| Room to grow? | Limited; form change needed | Yes |
| Best for | A single owner-operated small business | Operating, holding, IP and finance companies |
If you are unsure, ask yourself who will own the company in two years. If the answer might include a company, an investor or a second business of yours that uses the same structure, choose the standard S.à r.l. from the start.
Frequently asked questions
Can a company buy a shelf SARL-S?
No. Only natural persons can hold shares in a SARL-S. A company that wants a ready-made Luxembourg entity should look at a shelf S.à r.l. instead.
Can I own several SARL-S companies?
No. You can be a shareholder in only one SARL-S at a time, apart from shares that pass to you after a shareholder’s death. You can hold shares in other types of company as well.
Do I need a notary to buy a SARL-S?
The share transfer can be recorded in a private or notarial deed. We confirm which formalities apply to the other changes you want, such as a new name.
What if my SARL-S outgrows its limits?
If it goes above 100 shareholders or above the SARL-S capital limit, it must change its legal form, usually to a standard S.à r.l.
Is a SARL-S better than a new SARL?
It can be cheaper to start, but the ownership rules are stricter. See our comparison of a shelf company and a new company and our company formation page.
