Affiliation to the social security legislation of one member state compulsary for cross-boarder employees within the E.U.

The old Regulation 1408/71 provided an exception to this principle: when a person simultaneously performed professional activities as an employee and as a self-employed person, it was possible to be affiliated to the social security system in one Member State as an employee, and in another Member State as a self-employed person (attachment VII).

Due to the entry into force of the new Regulation 883/2004 on 1 May 2010 this double affiliation was abolished. The person in the aforementioned situation can now only be affiliated to the social security system of the Member State where he is an employee.

The provisions of the new Regulation will only apply to existing dual-registered individuals upon their specific request. Otherwise, on condition that the actual labour situation does not change, the provisions of Regulation 1408/71 will apply for a period of ten years.
