Notify the Künstlersozialkasse of any changes in legal circumstances.
Source: BUS Rheinland-PfalzThe Künstlersozialkasse (KSK) determines the levy obligation for your company and calculates the amount of the artists' social security contribution.
If the legal circumstances change, the KSK must check whether this affects your current or future levy obligation.
It is possible that the KSK will find out in other ways if the legal circumstances of your company change. In this case, the KSK will also check whether the change affects your tax liability, for example.
