On voluntary payments into the Spanish pension fund 

The petitioner, who has lived in Spain for almost 20 years, is complaining of unequal treatment concerning voluntary payments into the pension system. She states that voluntary payments are not possible in Spain, unlike in Germany. Instead, the petitioner claims she has to register as self-employed and also pay into the Spanish health and unemployment insurance. Swiss citizens have the option of only paying into the pension fund. The petitioner therefore asserts that EU citizens are being given unequal treatment compared to non-EU citizens.
