VAVplus since 2025, usually cheaper says AKBS
Since 2025, households can settle accident insurance directly through the office, with cover from SOLIDA Versicherungen AG. AKBS describes this route as «in der Regel kostengünstiger und administrativ noch einfacher» (as a rule cheaper and even simpler to administer). It is only offered in the form «Abrechnung mit Steuerabzug - vereinfachtes Verfahren».
