The Digital Services Act (DSA), which aims at regulating digital services and combating illegal content online, has been fully applicable across Europe since 17 February 2024. In Luxembourg, Bill No. 8309 on the implementation of the DSA was adopted by the Chamber of Deputies (Chambre des Députés) on 2 April 2025, and the law entered into force on 11 April 2025.

According to Article 2 of the law, the Luxembourg Competition Authority was officially designated as the competent authority for the application of the DSA, thereby assuming the role of Digital Services Coordinator (DSC). It is responsible for monitoring, enforcing and coordinating the implementation of the DSA in Luxembourg, in cooperation with other national authorities. Under Chapter 3, the Competition Authority has investigative powers (requests for information, inspections) and sanctioning powers, which can go up to 6% of a platform's global turnover in the event of non-compliance with the DSA (Article 15 of the law). The authority set up, in collaboration with the Centre des technologies de l’information de l’État (CTIE), a dedicated complaint service accessible via MyGuichet.lu for users.

The Luxembourg DSC will cooperate with institutions such as the CNPD on data protection, ALIA on audiovisual content and ILNAS on dangerous products. It is worth noting that, on 11 March 2025, the Competition Authority and seven other authorities concluded a cooperation agreement to ensure the uniform and consistent application of the DSA in Luxembourg.

Approximately 250 online platforms established in Luxembourg are affected by the DSA. The obligations include:

- the possibility for users to report illegal content

- the prohibition of targeted advertising to minors

- greater transparency on recommendation and advertising systems

- the rapid removal of illegal content (hate speech, sale of dangerous products, terrorist content, etc.).

Very large platforms (more than 45 million users in the EU) remain under the direct supervision of the European Commission, with the assistance of the Luxembourg Competition Authority for investigations concerning them. To date, the European Commission has identified and designated 25 very large platforms.

The national implementation of the DSA has now been finalised in Luxembourg. The legal framework has been fully in force since April 2025.
