Luxembourg Company Formation & Registration: Complete Step-by-Step Guide 2026

Luxembourg consistently ranks among the world’s most competitive business environments. Its central European location, political stability, AAA credit rating and extensive tax treaty network make it the preferred jurisdiction for holding companies, investment structures, European headquarters and financial services businesses.

Why Form a Company in Luxembourg?

• Strategic location — at the crossroads of France, Germany and Belgium, with direct access to EU markets
• Extensive treaty network — 80+ double tax treaties reducing withholding taxes on dividends, interest and royalties
• Participation exemption — full exemption from CIT on qualifying dividends and capital gains from subsidiaries
• IP Box regime — 80% income exemption on qualifying intellectual property income
• Multilingual workforce — English, French, German and Luxembourgish in daily business use
• EU regulatory access — EU passporting for financial services, funds and insurance

Choosing Your Entity Type

For international holding structures and investment vehicles, the SARL remains the most commonly used form due to its simplicity and governance flexibility. For structures requiring freely transferable shares or multiple share classes, the SA is preferred.

The Incorporation Process: Step by Step

Step 1 — Name Reservation & Availability Check

We search the RCS to verify the proposed name is available and compliant with Luxembourg naming rules. We reserve the name if required.

Step 2 — Draft Articles of Association

We prepare tailored statuts covering: share classes, transfer restrictions, quorum and majority rules, board composition, reserved matters, and special investor or manager rights.

Step 3 — Deposit Share Capital

Minimum capital is deposited in a Luxembourg bank. The bank issues a certificat de blocage confirming receipt. Funds are released upon RCS registration.

Step 4 — Execute Notarial Deed

Articles of association are executed before a Luxembourg notary as an authentic act. Shareholders unable to attend can grant a notarised power of attorney. We coordinate the notary appointment and prepare all identification documents.

Step 5 — RCS Registration & RESA Publication

The notary submits the deed to the RCS. The company receives a unique registration number. The constitutional notice is published in the RESA — giving the company legal existence vis-à-vis third parties.

Step 6 — Tax Registrations & Business Permits

We handle registration for corporate income tax, VAT, and — if required — the autorisation d’établissement (business permit) from the Ministry of the Economy.

Substance Requirements & Tax Residency

A Luxembourg company is tax resident if incorporated here or if it has its effective place of management in Luxembourg. Since 2017, demonstrating genuine substance is essential for claiming treaty benefits and avoiding challenge by tax authorities.

Key substance indicators:

• Board meetings held in Luxembourg with a quorum of resident directors
• Strategic decisions made in Luxembourg
• At least one director with genuine decision-making authority and Luxembourg ties
• Adequate staff proportionate to activities
• Accounting records maintained in Luxembourg

Luxembourg Holding Structures & Tax Benefits

Participation Exemption

Dividends and capital gains from qualifying participations are fully exempt from Luxembourg CIT. Conditions: the Luxembourg company must hold ≥10% (or €1.2M cost) of the subsidiary for an uninterrupted period of 12 months.

Withholding Tax on Outbound Dividends

Luxembourg levies a 15% WHT on dividends paid to shareholders. Reduced to 0% under the EU Parent-Subsidiary Directive (qualifying EU parents holding ≥10% for 12 months) and to treaty rates under applicable double tax treaties.

IP Box Regime

Luxembourg’s IP Box provides an 80% income exemption on net income derived from qualifying intellectual property — patents, software copyrights, utility models, and supplementary protection certificates — resulting in an effective tax rate of approximately 4.99% on qualifying IP income.
