Millions of dollars in refunds are required from Warburg Bank.
Warburg Bank, a major German financial institution, has suffered a legal setback in its dispute over a 155 million euro tax refund claim related to the Cum-Ex scandal. The Federal Finance Court in Munich has rejected the bank's appeal, upholding the Hamburg Finance Court's decision from November 2023.
The Cum-Ex scandal, a multi-billion-euro loss for the German state, involved complex stock transactions that allowed multiple parties to claim refunds of withholding tax on dividend payments, swiftly traded around the dividend record date. This scheme exploited legal loopholes in dividend taxation systems, particularly in Germany and other European countries.
Warburg Bank paid the 155 million euros in 2020 under protest and has since been trying to get the money back through legal means. The tax authority demanded the sum from Warburg Bank for the years 2007 to 2011, primarily due to refunds in fraudulent Cum-Ex transactions.
History and Mechanics
Cum-Ex trading became prominent around 2007–2011 and involved intricate share transactions around dividend payouts. Key actors were fully aware of the fraud mechanisms, and investigations revealed involvement by multiple banks and financial institutions, including some linked internationally.
One of the key figures in the scandal was Dr. Kai-Uwe Steck, a German lawyer and financial engineer, who advised banks and fraudulent actors on how to claim these tax refunds. Steck was convicted in June 2025 for tax evasion related to cum-ex transactions.
Legal Developments
Courts in Europe, including Germany and Denmark, have prosecuted central actors. For example, Sanjay Shah, a British hedge fund manager, was sentenced in 2024 to 12 years for tax fraud related to cum-ex deals that cost the Danish and other European tax authorities billions.
Steck’s conviction in 2025 marks a milestone in tightening legal scrutiny and consequences for those involved in cum-ex fraud schemes. Several banks have faced investigations, fines, and provisions for financial outflows related to their historical involvement in cum-ex transactions. Investec Bank, for instance, acknowledges its historical involvement through employees and faces ongoing civil and criminal investigations by the German authorities but denies wrongdoing.
Political Implications for Warburg Bank and Olaf Scholz
Warburg Bank has been one of the German banks deeply implicated in cum-ex investigations and trials, facing accusations of facilitating these tax fraud transactions. The scandal has intensified scrutiny and legal proceedings concerning their historical role in the fraud.
Olaf Scholz, Germany’s Chancellor (previously Finance Minister), has faced significant political pressure due to the cum-ex scandal because some of these schemes happened under his watch in the Finance Ministry (around 2010). Critics have questioned whether his administration gave adequate oversight or took sufficient action to curb the fraud, sparking debates over political responsibility and transparency.
Scholz has denied any personal wrongdoing, and as of mid-2025, no formal charges have been brought against him. However, the scandal has remained a source of political controversy, impacting public trust and raising calls for further investigations and regulatory reforms.
