The Danish Parliament has adopted a series of strict requirements for posting foreign workers to Denmark to prevent illegal labour and social dumping. Stricter documentation requirements under the Register of Foreign Service Providers (RUT) took effect on January 1, 2026. Employers posting non-EU/EEA nationals to Denmark must now upload specific additional documents directly to the RUT portal. This includes a copy of the service agreement between the foreign service provider and the Danish client.
Employers must also upload copies of employment contracts and valid residence and work permits for each posted third-country national. If an EU-established company posts a third-country national, they must upload a copy of the worker's valid work and residence permit from that country of establishment. A RUT registration does not substitute for a required work and residence permit. Sponsoring employers must still submit a separate permit application to SIRI for non-EU citizens.
On-site enforcement has also increased across Danish workplaces. Since January 1, 2025, all employees working on Danish sites must carry and present valid identification upon request. The Danish Working Environment Authority (Arbejdstilsynet) and the Danish Agency for International Recruitment and Integration (SIRI) conduct inspection visits to verify these IDs. Failure to present valid identification during an inspection can result in immediate enforcement notices and financial fines.
Furthermore, stricter housing laws now regulate how employers accommodate their staff. Under the Act on Accommodation of Employees, Arbejdstilsynet is empowered to inspect employee accommodations. These accommodations must meet specific standards, including protection against moisture, cold, and heat, as well as adequate access to daylight. Employers must also guarantee access to a clean toilet, drinking water, and adhere to strict limits on the number of people in a single housing unit.
