Employment, Social Affairs and Equal Opportunities EU Social Security Coordination
On May 1, 2010 the present Regulations 1408/71 and 574/72 have been replaced by the new social security coordination Regulations No 883/2004 and 987/2009 in the EU.
The new rules are applicable in Switzerland from 1 April 2012 and in Norway, Liechtenstein and Iceland from 1. June 2012.
The third country nationals, legally residing in the territory of the EU (except UK and Denmark), are covered with the new rules since 1. January 2011.
The coordination neither sets out which benefits should be paid to a person by one country or another nor establishes the size of pensions and benefits. Countries must ensure that people moving from one member state to another do not find themselves worse off than those who live and work in one member state their whole lives.
In order for people to be able to freely choose a country in the European Union, Switzerland, Norway, Liechtenstein and Iceland to live and work in, they must be guaranteed certain social insurance rights. These include sickness and maternity benefits; invalidity (incapacity for work), old age and survivor’s pensions; occupational accident and illness benefits; death grants; benefits payable to the unemployed; and family benefits.
The payment of the social insurance benefits mentioned above is organised by the Estonian Social Insurance Board, the Estonian Health Insurance Fund and the Estonian Unemployment Insurance Fund.
