Do I have to register my domestic help with the German Health Insurance Fund?

Regular employment
As long as the de minimis limit for mini-jobs (538 € per month) is not exceeded, you are not legally required to register your domestic help with the health insurance fund. However, if the de minimis limit is exceeded, you must register your cleaner with the statutory health insurance fund.
In this way, your domestic help is protected from the negative consequences of invalidity, loss of income and unemployment in the event of an emergency.

Self-employed domestic help and cleaning companies
No, you do not have to register a self-employed domestic helper or cleaning company.
