Denmark has introduced several important updates to its employment laws for 2025 and 2026, especially in relation to posted workers and foreign service providers. These changes build on existing rules under the Danish Posting of Workers Act, the Danish Immigration Act, and the requirements linked to the Register of Foreign Service Providers (RUT). The aim is to increase transparency, improve worker protection, and make compliance clearer for companies operating across borders.
Stricter Requirements for Posted Workers – Effective 1 January 2025
From 1 January 2025, foreign companies posting workers to Denmark face tighter obligations. All postings must be registered in the RUT system before work begins, regardless of how short the assignment may be. This requirement has been confirmed by the Danish authorities and applies across all sectors.
In addition, posted workers must be able to present valid identification during inspections carried out by the Danish Working Environment Authority or the Danish Agency for International Recruitment and Integration (SIRI). This ID requirement comes from updates made to both the Posting of Workers Act and the Immigration Act, and it marks a move toward more active enforcement.
Enhanced RUT Registration Obligations – Effective 1 January 2026
Further changes take effect on 1 January 2026. Foreign companies posting third‑country nationals to Denmark will need to upload additional documents to the RUT system. This includes employment contracts, service agreements, and relevant work or residence permits. The Danish government stresses that RUT registrations must be complete, accurate, and updated whenever assignment details change, including workplace locations and time periods.
Working Time Registration Law – In Force Since 1 July 2024
Since 1 July 2024, all Danish employers have been required to use a compliant working time registration system that records each employee’s daily working hours. This rule is linked to Denmark’s obligation to fully implement EU working time standards and remains fully enforceable through 2025 and 2026. Employers are expected to maintain clear and reliable records to show compliance if requested by inspectors.
Leap29 Recommendations
From 1 January 2026, the updated RUT requirements will mean that companies must upload more detailed documentation — including service agreements, employment contracts, and the appropriate work or residence permits — before any work begins in Denmark. Alongside these new obligations, businesses will still need to follow Denmark’s wider posting rules, workplace standards, and worker‑protection laws set out in official Danish labour regulations. Staying organised and ensuring all information is accurate and up to date will be essential for smooth compliance.

“Denmark’s latest compliance updates are a strong reminder that cross‑border work is evolving fast—and for good reason. These rules bring more clarity, more protection, and higher expectations for accuracy, all designed to make sure posted workers are properly supported. It’s a great moment for organisations to refresh their processes and rethink how they manage mobility.
