Key takeaways
- German posting limits can be extended from 12 to 18 months by notifying customs before the initial period expires.
- The extension notification must be written in German and sent electronically to mitteilung.langzeitentsendung@zoll.de.
- Replacing a worker on the same task means their posting durations are added together to determine the limit.
- Failure to comply with German working conditions or notification rules carries administrative fines of up to €30,000.
The 12-Month Posting Limit in Germany
Cross-border postings to Germany are subject to strict regulatory timelines. Under the German Posted Workers Act (AEntG), a standard limit of 12 months applies to temporary assignments. Once a posted worker exceeds this 12-month threshold, almost all local German working conditions and labor laws apply to their employment contract. This change can significantly increase payroll costs and administrative burdens for foreign employers.
To avoid the immediate application of these extensive local regulations, employers can extend the standard period. The German framework allows companies to extend the threshold to up to 18 months. To secure this six-month buffer, the employer must submit a motivated notification to the German Customs Administration before the initial 12-month period of employment in Germany expires.
What Changes After 12 Months: Extended Local Working Conditions
When a posting crosses the 12-month threshold—or the 18-month mark if an extension was approved—the legal status of the worker shifts. From that day forward, the host-country regulations of Germany govern almost the entire employment relationship. This transition means the employer must align the worker's terms with local German standards, even if the original employment contract was signed in another EU member state.
Under these long-term rules, posted workers gain the right to receive additional local benefits that are standard in Germany. These benefits include universally applicable collective agreement wages, Christmas pay, and supplementary holiday pay. Furthermore, if the work involves hazardous environments, employers must pay local bonuses for dangerous or dirty work. These mandatory additions can alter the financial calculations of a long-term project.
However, the transition to German labor law is not entirely absolute. The Posted Workers Act carves out a few specific exceptions to protect the integrity of the original employment relationship. Specifically, host-country rules do not apply to procedural rules regarding contract termination, post-contractual non-compete clauses, and supplementary occupational pensions. These three areas remain governed by the laws of the worker's home country.
