Alleged tax evasion on dividend payments
The allegations involve so-called “cum-cum” trades, which are questionable transactions that aim to acquire tax advantages in connection with the payment of dividends. Authorities are looking into allegations that banks were helping foreign clients avoid paying taxes by temporarily holding their shares in French companies when dividends were due.
The raids aimed to gather evidence to determine whether banks deliberately attempted to help clients avoid taxes as dividends were traded.

The financial prosecutors’ actions come in the wake of similar dividend scandals in Germany where governments were tricked into refunding dividend taxes that were not paid to begin with. These investigations in Germany, which led to raids of banks and homes of businesspeople have resulted in some bankers receiving jail sentences. The fraud reportedly cost billions of euros in taxpayers’ money.
The raids in Paris also come on the heels of the international financial upheaval caused earlier this month by the failure of two banks in the United States, and the takeover by UBS of embattled lender Credit Suisse of Switzerland.
