A letter from the Familienkasse: what it means and how to keep Kindergeld in 2026
Short answer
Most often the Familienkasse asks for a document: a school certificate (Schulbescheinigung), proof that a child over 18 is still in education, a new residence permit or an address change. Missing the deadline can stop the payment.
