Eckdaten
Schritt-für-Schritt-Gründungsprozess
Draft the articles of incorporation
Prepare the Satzung (articles of incorporation) defining the share capital structure, par value of shares, governance bodies, and business purpose. The AG requires both a management board (Vorstand) and a supervisory board (Aufsichtsrat).
Notarial certification and founding meeting
All founding shareholders attend a notarised founding meeting. The notary certifies the articles of incorporation, records the subscription of shares, and documents the appointment of the first supervisory board and auditor.
Appoint supervisory board and management board
The supervisory board (minimum three members) is appointed by the founders. The supervisory board then appoints the management board (Vorstand). Companies with more than 500 employees must include employee representatives on the supervisory board.
Deposit share capital
Open a bank account and deposit at least 25% of the nominal share capital (€12,500 minimum). Contributions in kind require an independent auditor’s valuation report.
Commercial register filing
The management board files the registration application with the Handelsregister through a notary. The application must include the formation report, auditor’s report (if applicable), and bank confirmation.
Tax and regulatory registration
Register with the Finanzamt, obtain a trade licence, and comply with any sector-specific regulatory requirements. Listed AGs must also register with BaFin (Federal Financial Supervisory Authority).
