In this episode, we explore the social security challenges faced by individuals who hold board mandates in Liechtenstein while residing in Switzerland or an EU state. These cross-border roles can complicate the determination of which social security system applies. We discuss the general rule that board members are typically subject to the social security system of their primary country of residence, but complexities arise when the board mandate in Liechtenstein is secondary or if the individual has no primary occupation in their home country.
