When you hire new staff, you must register these employees with social security. This registration obligation applies to all your employees. This means that you not only have to register your employees who are subject to social insurance contributions, but also, for example, marginally or short-term employees, trainees, working students or employed pensioners with the social insurance. The registration procedure is the same for all employees, with the exception of mini-jobs in private households. You must submit social insurance notifications electronically. If you use a system-checked payroll accounting program in your company, you can create and send the notifications with this program. This is largely automated. Alternatively, you can use a system-checked completion aid to transfer the data to the social insurance agency. The Informationstechnische Servicestelle der gesetzlichen Krankenversicherung (ITSG GmbH) offers "sv.net", a system-checked completion aid that you can use for the notification. The program is free of charge up to a certain usage limit. System-tested payroll accounting programs and completion aids also contain the necessary modules for all other electronic notifications to the social security system that you are obliged to make as an employer. In addition to the registration, the monthly contribution statement and the annual statement are particularly important. In some industries, you must submit an immediate report in addition to the registration. To register employees, you must provide the following information, among other things: Personal information: For this purpose, ask to see official documents, such as your identity card. Social security number: You will find this on the employee's social security card. If you do not have the card, you can also register new staff without a social security number. In this case, you must provide the date and place of birth and, if applicable, the country and name of birth. Collection agency: The responsible collection agency is usually the employee's statutory health insurance fund; for part-time employees, it is the Minijob-Zentrale. To prepare the registration, you can use the "Information Portal for Employers" of the Information Technology Service Center of the Statutory Health Insurance (ITSG). This information portal helps you to classify the employment relationship in terms of social insurance law and to compile all the necessary data.
