Liberal Professions That Need a Business Permit in Luxembourg

In Luxembourg, certain liberal professions require a business permit (autorisation d’établissement) AND a recognised diploma in the field. These are regulated professions — you cannot just declare yourself an architect or accountant without proving your qualifications.

Other liberal professions are governed by separate laws and ministries — see the section “Liberal professions outside the business permit system” below.

What is a “liberal profession”?

A liberal profession is an intellectual, regulated activity that is not commercial, artisanal, or industrial. Common features:

• You sell expertise, not goods
• The activity is regulated (a diploma is required by law)
• There is usually a professional body (ordre or chambre)
• You are personally responsible for your work

If your activity is intellectual but not regulated by a specific diploma requirement (for example IT consulting, marketing consulting, translation), it is generally classified as commercial, not liberal. We covered this in our article on IT consultants: commercial or liberal?

Architects, engineers, accountants — the regulated diploma route

For these professions, you need:

• A specific diploma, checked by the Ministry of Economy with your permit application
• A business permit (autorisation d’établissement) — same 4 criteria as any business: integrity, qualification, fixed premises, effective management
• Registration with the relevant professional body (OAI for architects and engineering consultants, OEC for chartered accountants)

Practical tip: The Ministry of Economy checks a foreign diploma with your business permit application. If it finds that the diploma does not meet the criteria, the recognition is done by the Ministère de la Recherche et de l’Enseignement supérieur (MESR) at mesr.gouvernement.lu. Architects with a diploma listed in Annex V of Directive 2005/36/EC are exempt. Start this process early — it can take weeks.

Liberal professions outside the business permit system

Some liberal professions are regulated under their own laws — they do NOT go through the standard business permit process:

For these, contact the relevant authority directly — the Ministry of Economy’s business permit does not apply.

What if your activity is not on these lists?

If your intellectual activity is not on the regulated list:

• You probably do not need a specific diploma
• You still need a business permit (general criteria apply)
• You are likely classified as a commercial activity, not a liberal profession

This applies to most modern consulting work: IT consulting, management consulting, marketing consulting, business coaching, copywriting, translation, design, training. See our article on activities that need no qualification.

Foreign diplomas — recognition process

If the Ministry of Economy finds, when it checks your permit application, that your foreign diploma does not meet the criteria:

1. Submit your diploma to MESR for recognition: mesr.gouvernement.lu — administrative fee 75 EUR
2. For EU diplomas, mutual recognition rules often apply (faster process)
3. For non-EU diplomas, the Ministry assesses equivalence — may require additional training or proof of experience
4. Once recognised, the recognition decision completes your business permit application

A non-recognised diploma will block your business permit application. Do not assume your foreign diploma is automatically valid in Luxembourg — even within the EU, the Ministry of Economy checks it.
