Meaning
An administrative mechanism allows an employee to work in another country for a limited period while remaining covered by their home country’s social security system. The practice of temporary detachment is utilized by multinational companies to avoid the administrative complexity of changing social security systems for short-term postings. It governs the social security status of the employee during the international assignment.
The status is restricted to a pre-determined duration, typically not exceeding twenty-four months.
Operational Framework
The employer must maintain a direct relationship with the employee throughout the assignment period. This requires that the employment contract remains active and the employer retains the right to terminate the relationship. The salary must also be paid by, or recharged to, the sending company.
Regulatory Compliance
To secure this status, the employer must apply for a certificate of coverage from the relevant authority before the assignment begins. In Europe, this is achieved by obtaining an A1 certificate under social security coordination rules. The application must prove that the worker has been subject to the home country’s system for a minimum period before the posting.
This requirement prevents companies from hiring workers solely for the purpose of immediate detachment to countries with higher contribution rates. Local labor inspectors in the host country frequently demand to see the certificate to verify that the employee is legally exempt from local social security taxes.
Continuation Right
If the assignment is extended beyond the initial period, the employer must request an extension from the authorities of both countries. These extensions are discretionary and require a demonstration of special circumstances to be approved. If the extension is denied, the employee must transition to the host country’s social security system, which can trigger additional administrative costs.
Careful planning is required to align these durations with the company’s broader mobility strategy.
