Welcome to the website of the Federal Social Insurance Office FSIO

The Federal Social Insurance Office (FSIO) is the national centre of expertise on policies related to old-age, invalidity and the family. It plans, manages and monitors the corresponding social insurance systems to ensure that they function effectively. The FSIO also initiates and coordinates reciprocal social security agreements with other countries. The Swiss Confederation spends about one third of its budget on social welfare. In recent years this amounted to about CHF 20 billion.
