Setting up a company in Luxembourg: the online procedures via MyGuichet

For anyone planning to set up a company in Luxembourg, most of the administrative process now takes place online, from the application for a business permit (autorisation d'établissement) through to registration in the trade and companies register. Here are the five digital steps to know, and where to find help if you get stuck.

Creating a professional space on MyGuichet.lu

The essential first step is to open a professional space on MyGuichet.lu, which serves as the entry point for almost all procedures related to setting up a company. Since 5 January 2026, the platform has offered a unified catalogue of services, with authentication and personal data retrieved automatically from authentic sources, which avoids re-entering the same information from one procedure to the next, according to a news item published by Guichet.lu. The new catalogue also includes a favourites function and a “Consultation” filter, useful for quickly finding a file in progress. The space is created by following a dedicated tutorial available on Guichet.lu, and is a technical prerequisite for the following steps, in particular the LuxTrust authentication required for regulated procedures.

Submitting a business permit application online

Any commercial or craft activity, or regulated profession, carried out in Luxembourg requires an autorisation d'établissement (business permit), issued after checks on the applicant's good repute and professional qualifications. The application is submitted entirely online on MyGuichet.lu, with mandatory LuxTrust authentication, replacing the paper filing previously required at the Ministry of the Economy, Guichet.lu states in a news item updated on 7 June 2024. A complete file is in principle processed within a statutory period of three months: if the administration has not replied by then, approval is deemed tacitly granted, a point worth knowing when planning the launch of the activity. The table below summarises the practical details of this step, set out on the dedicated Guichet.lu page.

For entrepreneurs used to other digital procedures, the strong authentication logic is similar to the one used for signing business documents: our article on the legal value of electronic signatures and LuxTrust explains this mechanism, used here to secure the filing.

Registering the company in the Trade and Companies Register

Once the business permit has been obtained, the company must be registered in the Registre de commerce et des sociétés (RCS, the Trade and Companies Register), managed by Luxembourg Business Registers (LBR). Articles of incorporation can be filed and registration completed electronically, with legal publications then made on the RESA platform, as Guichet.lu and Luxembourg Business Registers explain. This shift online reduces the in-person visits and postal delays that used to lengthen the setup process, a strong argument for entrepreneurs looking to start trading as quickly as possible.

Getting support from the House of Entrepreneurship

Faced with so many procedures, entrepreneurs are not on their own: the House of Entrepreneurship is a one-stop shop that centralises support, from preparing the file to following up the business permit application. It brings together more than thirty public and private partners, including ADEM, Luxinnovation, LBR, IPIL and SNCI, to direct founders free of charge to the right contacts for their sector of activity, according to Guichet.lu. If a file gets stuck, whether on MyGuichet authentication, gathering the documents or following up the permit, direct contact remains useful:

• Telephone: +352 42 39 39 330
• Opening hours: Monday to Friday, 8.30am to 12pm and 1pm to 5pm
• Partners available: ADEM, Luxinnovation, LBR, IPIL, SNCI, among others

Checking eligibility for the first-time business creation grant

A final step not to overlook: the application for the aide à la primo-création d'entreprise (first-time business creation grant), also available via MyGuichet.lu. This procedure also requires authentication, which confirms the value of having a properly configured professional space on the platform from the outset, according to Guichet.lu. Entrepreneurs should therefore check their eligibility early rather than after launching the activity, so that the grant can be built into their initial financing plan.

Overall, the company setup process in Luxembourg has moved largely online: the MyGuichet professional space, the business permit, RCS registration and the grant application now rely on the same digital tools, with free in-person support available if needed through the House of Entrepreneurship.
