Registration at the National Insurance Institute as a Kibbutz member is automatic, via information received from the Kibbutz.
If information is not received automatically by the NII, you must provide the Insurance and Collection Department with an authorization from the Kibbutz, mentioning the duration of your Kibbutz membership, as well as the Kibbutz's deductions file number.
The authorization can be sent by means of the internet site or submitted to your local NII branch.
