If you employ staff, you must notify the social insurance of the remuneration of these employees that is subject to contributions. To do this, you must submit an annual declaration for all employees working for you on 31.12. of a year by 15 February of the following year. Only employees who are exempt from insurance for a short period of time do not have to submit an annual return. If the employment relationship ends during the course of the year or on 31.12. of a year, you inform the employer of the earnings subject to contributions as part of the deregistration. Annual notification is then no longer required. If the employment relationship is interrupted, you report the pay liable for contributions as part of the interruption report. An annual notification is then no longer required for the periods already notified. You must submit the annual or remuneration declaration electronically, like all other social insurance declarations. If you use a system-checked payroll program in your company, you can create and send the notifications using 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 Information Technology Service Center for Statutory Health Insurance (ITSG GmbH) offers "sv.net", a system-checked completion aid that you can use for the remuneration notifications. The program is free of charge up to a certain level of use.
