How Long Does It Take to Become Self-Employed in Luxembourg?

From “I want to start a business” to sending your first invoice usually takes 1–2 months if you are already an EU/EEA resident, and up to 3+ months if you are a non-EU national moving to Luxembourg. The business permit itself took 6.62 days on average in 2025, according to the Ministry of the Economy, but preparation and follow-up registrations add real time.

These are typical cases. Missing documents, foreign diploma recognition, or a complex activity can extend any stage by weeks. Plan with a buffer.

Stage 1: Preparation (1–4 weeks)

Before you apply for a business permit, you need to decide three things and gather documents:

• What activity are you doing? Commercial, liberal profession, or craft? Does it need a qualification? See business activities that need no qualification, liberal professions, craft activities, and specific guides for HORECA, transport, and real estate.
• Which legal form? Sole proprietorship is fastest and cheapest; a SARL or SARL-S adds 1–2 weeks for registration, and a SARL also needs a notary — the law of 10 August 1915 on commercial companies lets a SARL-S be formed by private deed. See which legal form for your business and sole proprietorship vs SARL.
• Do you meet the 4 criteria? Qualification, clean professional history (your tax and social-security charges paid included), fixed place of operation and effective management — the conditions Guichet.lu lists for the business permit. See the 4 criteria for a business permit.

Documents you need to gather:

• Criminal records from every country of residence over the last 10 years (this is the usual bottleneck for non-EU nationals)
• Proof of qualification (diploma, certificate, work experience) if your activity is regulated
• The address of your premises in Luxembourg — the lease or other proof can follow once the ministry has examined your application, as the application form says
• ID and residence documents

Practical tip: Start gathering criminal records the moment you know you want to start a business. Some countries take 4–8 weeks just to issue a certificate, and they often must be apostilled and translated.

The guides on the steps in this timeline are gathered under becoming self-employed.

Stage 2: Business permit application

You apply via MyGuichet.lu or by post, pay the 50 EUR fee, and wait — 6.62 days on average in 2025, according to the Ministry of the Economy’s review of 2025. For full detail see how to apply for a business permit.

Tacit approval rule: If the Ministry of Economy does not respond within 3 months of receiving a complete application, your business permit is considered granted. You can then demand confirmation. This is a safety net — do not rely on it as a plan A.

Nationals from outside the EU, the EEA and Switzerland: You typically also need a residence permit for self-employed activity (titre de séjour pour travailleur indépendant). It is tied to the business permit: as Guichet.lu’s page on the visa D for self-employed residence explains, your visa D application, made from abroad, must include the Ministry of the Economy’s opinion in principle (avis de principe) on your business permit; the visa D is valid for 6 months, and once you have arrived you apply for the residence permit itself, with the Ministry of Home Affairs. This adds 2–3 months on top. EU, EEA and Swiss nationals do not need this.

Watch out for the opposite silence rule on the residence permit: if the immigration authority does not respond within 3 months, you may treat the application as rejected and appeal to the administrative court, as Guichet.lu’s note on processing times explains — it is not granted. Non-EU applicants should actively chase confirmation, not assume tacit approval.

Stage 3: Post-permit registrations (2–4 weeks)

Once your permit is in hand, you have up to four registrations to handle — all covered in detail in what to do after you get your business permit:

• CCSS — submit declaration of entry (déclaration d’entrée pour travailleurs indépendants) within 8 days; confirmation letter arrives in about 1 week
• VAT (AED) — submit the initial declaration within 15 days of starting, franchise or not: article 62 of the VAT law requires every taxable person established in Luxembourg to declare the start of its activity and gives each a VAT number, and article 1 of the Grand-Ducal Regulation of 1 December 2009 sets the 15 days; the number is issued a few weeks later. Article 2 of the same regulation lifts the duty when your whole activity is VAT-exempt under article 44 of the VAT law without a right to deduct, as a doctor’s care is
• RCS — if you trade in your own name and your activity is commercial, register on lbr.lu within a month: article 15 of the Loi du 19 décembre 2002 sets one month from the event for every registration the law requires
• ACD — tax file usually opens on the back of your permit + CCSS affiliation; verify after a few weeks

Also do these in parallel:

• Open a business bank account (1–3 weeks)
• Take out professional liability insurance if required or advisable
• Register with your professional body if required (OAI for architects, OEC for experts-comptables); a craft business joins the Chambre des Métiers automatically — the law reorganising the Chambre des Métiers makes it a member from the day its permit is granted

Practical tip: You can do a lot of this before your permit arrives. Open the business bank account with your application receipt, compare insurance quotes, prepare your invoicing tools. Parallelizing can save you 2–3 weeks.

Stage 4: First invoices and ongoing obligations

With your permit, CCSS matricule, and VAT number in hand, you can start invoicing. Ongoing obligations kick in immediately:

• Monthly CCSS invoices from day 1 of activity
• VAT returns (monthly, quarterly, or annually depending on turnover)
• Annual income tax return — Form 100 (main return) plus Form 110 annex (commercial/craft profit) or Form 152 annex (receipts-minus-expenses method, common for liberal professions)
• Quarterly advance income tax payments — usually from your first assessment, though the ACD’s FAQ says it may set them on an estimate of your income when there is no earlier return or assessment

For all of the above, see what taxes do self-employed people pay in Luxembourg and CCSS for self-employed.

Common causes of delay

Most delays come from a handful of recurring issues:

• Incomplete criminal records — missing a country of residence from the past 10 years
• Foreign qualifications not recognised — a qualification from outside Luxembourg may need an equivalence from the Education ministry, which answers in 2–6 weeks and at most 3 months, says Guichet.lu, or, for a higher-education diploma, a recognition or a register entry at the MESR, whose register of titles takes 4–6 weeks on average; €75 each
• No proof of fixed premises — see what counts as a fixed place of operation
• Unclear activity description — vague application text leads to requests for clarification
• Missing qualification for regulated activity — see how to prove a clean professional history and the qualification guides above
• Non-EU residence permit application — can extend the full journey to 4–6 months

If you are moving to Luxembourg from outside the EU, the EEA and Switzerland to start a business, start with the business permit: the Ministry of the Economy’s opinion in principle goes into your visa D application, so the two steps follow one another rather than running in parallel.

What you can do in parallel (save time)

Practical tip: Below 50,000 EUR turnover you can use the VAT franchise and charge no VAT, but you still register when you start, as the VAT law requires (see Stage 3): the AED’s FAQ on the franchise says the franchise is requested in that initial declaration. See 100,000 EUR EU VAT franchise for small business.
