IT Consultant in Luxembourg: Commercial or Liberal Profession?
If you’re an IT consultant, software developer, web designer, or any kind of general consultant starting out in Luxembourg — your activity is classified as commercial, not as a liberal profession. This surprises many freelancers, but it matters for your taxes, registration, and which chamber you belong to.
| Question | Answer |
|---|---|
| IT consulting classification | Commercial |
| General consultancy (marketing, management, etc.) | Commercial |
| Web/app/software development | Commercial |
| Chamber | Chambre de Commerce (cc.lu) |
| Registered in RCS? | Yes |
| Municipal business tax? | Yes (after 40,000 EUR profit allowance) |
Why IT consulting is commercial
In Luxembourg, liberal professions are specifically defined — they include professions like architects, chartered accountants (experts-comptables), lawyers, doctors, and engineers. These are regulated professions with professional bodies (OAI, OEC, Barreau, etc.).
IT consulting, software development, general management consulting, marketing consultancy and similar activities do not fall into this category. They are classified as commercial activities (activites commerciales / gewerbliche Tatigkeiten) — even if the work is purely intellectual.
This is not a choice you make. The classification is determined by Luxembourg law based on the nature of the activity, not by how you describe yourself.
What this means for you
Registration
- You register with the Chambre de Commerce (cc.lu), not a professional order
- You are registered in the RCS (Registre de commerce et des sociétés) at LBR
- Your business permit is issued as a commercial permit
Taxes
- Income tax — same as liberal professions (progressive rates, Form 100)
- Municipal business tax (impôt commercial communal) — YES, this applies to you. Commercial activities pay municipal business tax on profit above 40,000 EUR. Liberal professions are exempt.
- VAT — same rules as everyone else
- CCSS — same rules as everyone else
- Tax forms — Form 100 + Form 110 annex (commercial/craft profit). Form 152 annex (receipts-minus-expenses method, commonly used by liberal professions) does not apply to commercial IT consulting.
The practical difference
| Commercial (IT, consulting) | Liberal profession (architect, CPA) | |
|---|---|---|
| Chamber | Chambre de Commerce | Professional order (OAI, OEC, etc.) |
| RCS registration | Yes | No |
| Municipal business tax | Yes (above 40k allowance) | No |
| Income tax form | Form 100 + 110 annex | Form 100 + 152 annex |
| Business permit | Yes | Yes |
| CCSS | Same | Same |
| VAT | Same | Same |
What about data analysts, graphic designers, translators?
These are also commercial in Luxembourg. The general rule: if your profession is not on the specific list of regulated liberal professions, it’s commercial. This includes:
- IT consulting and development
- Marketing and communication
- Management consulting
- Graphic design
- Translation and interpreting
- Training and coaching
- Data analysis
- E-commerce
- Event management
Practical tip: If you’re unsure about your classification, contact the House of Entrepreneurship (houseofentrepreneurship.lu) — they offer free guidance and can confirm your activity type before you apply for a business permit.
Not every day is easy when you work for yourself. But every day, you’re building something that’s yours.
