Safe and sound during assignments abroad
In the case of a posting, workers pursue their activity in another Member State on a temporary basis. If employees are posted abroad on business by their employer, insurance contributions abroad may be payable in addition to social security contributions in Austria. In order to prevent this, posted employees need the so-called A1 form as proof of posting. They can use it to document which social insurance system is responsible for them in an EU/EEA country.
