Frequently Asked Questions
Why is Luxembourg a financial hub?▾
Luxembourg offers political stability, a multilingual workforce, favorable holding company and fund regimes, extensive double taxation treaty network (80+ countries), and is the EU's largest domicile for investment funds (over €5 trillion AUM).
What is a S.à r.l.?▾
S.à r.l. (Société à responsabilité limitée) is Luxembourg's limited liability company. Minimum capital is €12,000. It's the most popular company form for holding structures and operating companies.
How do I search Luxembourg companies?▾
The RCS portal (lbr.lu) provides free access to company data. The RESA (Recueil Électronique des Sociétés et Associations) publishes official company announcements.
What is a SCSp?▾
SCSp (Société en commandite spéciale) is Luxembourg's special limited partnership, widely used for private equity and venture capital fund structures. It offers tax transparency and governance flexibility.
How do I search for a company in Luxembourg by name?▾
Type the company name into the search box above. Results come from the RCS Luxembourg and show the registered name, RCS number, status and registered address. Partial names work — searching "acme" returns every registered entity whose name starts with it.
Is the Luxembourg company register free to search?▾
Yes. Searching by company name or RCS number is free here and on the official Luxembourg register — no account or payment is required for a basic lookup. Certified extracts and filed documents may carry a fee on the official register.
Can I search Luxembourg companies by registration number?▾
Yes. Enter the RCS number instead of the name and the lookup resolves it directly to the matching record, which is the fastest way to confirm an identifier printed on an invoice or contract.
How do I check whether a company is registered in Luxembourg?▾
Search the name or RCS number above. If the business is on the RCS Luxembourg, the record appears with its registered name and identifier. If nothing is returned, the name as spelled is not on the register — try a partial name or the number printed on the invoice or contract before concluding the business is unregistered.
How can I tell if a Luxembourg company is still active?▾
Each record carries the status the RCS Luxembourg publishes for that entity. Registration status is a factual register field, not a judgement about the business — for ongoing certainty you can watch a record and be emailed when its registered details change.
How do I find a company's RCS number?▾
Search the company name above. Each result shows its RCS number alongside the registered name, status and address, sourced from the RCS Luxembourg.
