INTRODUCTION As a country, Switzerland is primarily an importer of foreign labour. But the relevant tax law is complex and can be difficult to navigate both for employers who post staff to our country and for employees planning to work here for a short period. In this article, our lawyers will take a look at tax liability for short-term and posted workers in Switzerland. We will also look at the taxation of cross-border workers and procedural considerations. ***** CROCE & Associés SA is one of only a few Swiss law firms to have specialised in immigration law for nearly fifteen years. We look after both family relocations, with or without gainful activity (lump-sum taxation, pensions, etc.) and residence permit applications for employees in Swiss, European and international businesses. Our lawyers file notifications for posted workers and handle applications for short- and long-term residence permits, 4-month or 120-day authorisations, settlement permits and even Swiss citizenship, all across Switzerland, working in French, Italian and German. Naturally, our services also cover other aspects of Swiss employment law (such as salary calculations and administrative procedures involving the foreign labour authorities), international tax law and social charges. ***** We will begin with some preliminary remarks: 1) It is important to make the distinction between posted workers and salaried employment in Switzerland. Posted workers are staff of an employer, whose business has its head office outside Switzerland, sent by this employer to Switzerland for a limited period of time to work on behalf of the employer and under its supervision as part of a contract for the provision of services signed between the employer and the recipient of the service in Switzerland, or to work for the employer’s subsidiary or a company within its group. In this last situation, it can be difficult to decide whether the person is a posted worker or a salaried employee in Switzerland. A posted worker remains under the direction of their employer abroad, and it is that employer who decides when the posting ends and makes any changes to working conditions. A posted worker has no employment contract with the Swiss company and is presumed to return to their home country at the end of the posting. Consequently, in contrast with a migrant worker in Switzerland, a posted worker is not integrated into the Swiss labour market.
