Cross-cutting practices
Global mobility in Luxembourg
Global mobility covers the secondment, expatriation and international contracts of employees in connection with Luxembourg. The firm structures these situations on the contractual, social and tax levels, bridging employment law and immigration law, for compliant and controlled mobility.
Moving an employee to or from Luxembourg raises interlocking questions: which contract, which social security regime, which taxation, which residence permit. Poorly structured mobility creates risks for both the employee and the employer.
Cerno Law Firm bridges employment law and immigration to structure secondments, expatriations and international contracts, and to secure the social and tax position of the mobility.
The need
You are organising the secondment, expatriation or global mobility of an employee to or from Luxembourg.
Contract, social regime, taxation and residence permit must be structured together.
The risk
Double social security liability, an unsuitable contract, an unsecured tax position, a missing residence permit.
Poorly framed mobility exposes the employer to reassessments and the employee to a loss of rights.

FAQ
Frequently asked questions
What is the difference between secondment and expatriation?
Secondment in principle keeps the employee attached to the home social security regime for a limited period; expatriation attaches the employee to the host country. The choice has social and tax effects that the firm structures.
Is global mobility a matter of employment law or immigration?
Both. It is precisely the bridge between employment contract, social regime and residence permit that must be mastered; the firm coordinates these aspects.
How do you avoid double social security liability?
Through a suitable structure and, where applicable, the relevant coordination instruments. The firm secures the regime applicable to the mobility.
Is an international contract essential?
In most mobilities, yes: it sets the applicable law, the remuneration and the conditions. The firm drafts it and coordinates it with the residence permit.
