In Germany, a broadcast fee (Rundfunkbeitrag) is due for all apartments. It does not matter whether and how one uses TV or radio. Even if there are no radios in the apartment at all, this fee must be paid.
If the fee is already included in the rent, the broadcast fee number (Rundfunkbeitragsnummer) should be communicated at the latest when handing over the apartment (noted in the handout form). This number is required for requests from the authorities.
If the broadcast fee is not included in the rent, lessees are responsible for registering the apartment themselves. Read more: Broadcasting fee →
