For the German broadcasting contribution, the key question is whether your room counts as a separate dwelling or forms part of a shared flat behind one shared entrance door. Check the actual layout first and use only the official Beitragsservice for registration, deregistration or an exemption.
Official classification
The Beitragsservice information for students and trainees explains the current distinction.
The current calculation is €18.36 per month and dwelling. The statutory payment is collected for three months at a time, amounting to €55.08; other advance-payment cycles are also available. Ordinary monthly payment is not offered.
If one person is already registered for the shared dwelling, the other residents can deregister using that person’s contribution number. Share the number only within the flat and never publicly.
Students receiving BAföG who do not live with their parents can apply for an exemption. Beitragsservice assesses further exceptions and hardship cases from the application and evidence; exemption is not automatic.
