The company presented on this webpage takes part in the project 5-Euro-Business. Within this project, students found a small company for limited time. Main focus of the project are an introduction to entrepreneurship as well as economic thinking and acting. 5-Euro-Business companies are according to German tax law small businesses, because the maximum turnover is significantly below 17500 Euro per year. The compliance with this limit is controlled by the project executing organisation. Therefore, according to German tax law, 5-Euro-Business companies neither calculate nor pay VAT. In case of any further enquiries, please contact the executing organisation.
