Field help:
Administrative office
Select the administrative office that is responsible for you.
Your family benefits office is not included in the list?
Then answer the question "Do you want to enter the family benefits office (Familienkasse) directly?" with "yes"." You will see a blank entry field in which you can enter the family benefits office responsible for you.
Note: It is mandatory to indicate the relevant family benefits office (Familienkasse) from the 2013 tax year onwards. It is not possible to submit the tax return via ELSTER without specifying the family benefits office.
