Before you can open your doors, register with the RCS or invoice a single client in Luxembourg, you need a business permit — the autorisation d'établissement. It's the single most common blocker for first-time founders, because the requirements are specific and the application isn't intuitive. This guide covers what it is, who needs one, the three pillars the Ministry checks, and where applications typically fail.

Who needs a business permit

Essentially anyone running a commercial, craft, or industrial activity in Luxembourg, plus most liberal professions (architects, accountants, consultants under regulated titles). If your company will do any of the following, you need the permit before you start:

  • Run a shop, café, or service business (commerce)
  • Produce or manufacture goods (industry)
  • Operate as a craftsman or artisan (craft — includes many trades)
  • Offer certain regulated professional services (liberal professions)

The permit is issued by the Ministry of the Economy (Ministère de l'Économie), specifically the General Directorate for Small and Medium-Sized Enterprises.

Read The Sàrl-S: how to incorporate in Luxembourg without a notary — and note: for a Sàrl-S, the business permit must be in place before RCS registration, which is the opposite order of what founders expect.

The three pillars

The Ministry assesses every application against three criteria. All three must be satisfied. Most rejections happen because the founder underestimated number 2 or 3.

1. Professional integrity (honorabilité)

You need a clean record. The Ministry checks the Luxembourg criminal record (bulletin nº 3). A recent bankruptcy or certain financial offences will block the application. For non-Luxembourg nationals, you'll typically need to provide an equivalent document from your country of origin, translated if not in French, German or English.

2. Professional qualification (qualification professionnelle)

This is where most applications get stuck. For craft and industrial activities, you must demonstrate relevant experience — typically a diploma, a certificate of apprenticeship, or several years of documented professional experience in the field. For commercial activities, the bar is lower but not zero: you need to show basic business management knowledge.

The Ministry publishes a detailed list of which activities require which qualifications. Guessing wrong costs you weeks and a re-filing. We map your exact activity against the official register before the application goes in.

3. Physical establishment in Luxembourg

You need a real, physical address in Luxembourg — not a virtual office, not a PO box, not your flat in Brussels. The Ministry requires a lease or property deed showing premises suitable for your stated activity. For a Sàrl-S, this is the registered office. For a shop, it's the commercial lease.

What founders typically get wrong

The single most common mistake: confusing the business permit with RCS registration. They are two separate steps — the permit comes first, issued by the Ministry; then the company is registered with the Luxembourg Business Registers (LBR). Filing the RCS application without the permit in hand will be rejected.

Second: underestimating the qualification requirement. If you've worked in the field for five years but never collected employment certificates, you have no evidence. The Ministry accepts certificates, diplomas, apprenticeship records, and employer attestations — but only if you have them ready.

Third: applying under the wrong activity category. Luxembourg's classification of commercial, craft and industrial activities is specific, and the category you pick determines which qualification rules apply.
