Families are supported by the state.
As soon as your children live in Germany the family is entitled to statutory children allowance (“Kindergeld”), which is a monthly net benefit of 204 € for one child, 408 € for two and 618 € for three children. For each further child the family receives 235 € (figures for 2020). Further reliefs consist in parental money (“Elterngeld”), parental leave (“Elternzeit”), and maternity allowance (“Mutterschaftsgeld”). The HR group will consult you in all these matters.
