Responsible authority

The registration must be sent to the relevant health insurance institution.

Process and procedure

The notification shall only be deemed submitted, if it is transmitted via ELDA (electronic data exchange with the Austrian social insurance institutions).

Registrations submitted by other means, in particular in paper form, by email or by telephone, are not deemed submitted.

The first monthly contribution base notification (mBGM) to be submitted confirms or corrects the details of the submitted declaration and therefore the type and scope of insurance. This then completes the registration obligation.

A valid social security number must be indicated on the registration. If you don't know your social security number yet, it must be requested alongside the submission of the notification by means of the social security number request. In this case, you must state your date of birth and the reference of the notification social security number request on the registration. If, in exceptional cases, it was not possible to submit the application for a social security number at the time of registration, the reference value for the application for a social security number must be entered subsequently through a corrective registration. The reporting office will be informed of the social security number via the clearing system.    

Specifics of the notification

After registration, the employee shall be immediately provided with a copy of it. To fail to do so is an administrative offence which can be punished with an administrative fine by the district administrative authorities.


The registration obligation is finally fulfilled by the electronic submission of the registration, followed by the timely transmission of the mBGM.
