Almost three years after UBS, Switzerland’s biggest bank, paid a $780 million fine for helping Americans evade taxes and agreed to hand over the names of more than 4,500 American account holders, the Swiss banking industry refuses to exit the business of tax evasion. And the Swiss government still insists on protecting it from scrutiny. The United States should not compromise in pursuing the data it needs on American tax cheats.

American authorities are rightly putting pressure on the Swiss. Last week, prosecutors from the United States Attorney’s Office in Manhattan indicted Wegelin & Company, Switzerland’s oldest bank, accusing it and three of its employees of helping American taxpayers hide more than $1.2 billion. Wegelin is scheduled to appear in Federal District Court on Friday.

Wegelin went so far as to lure some 70 former UBS clients, claiming to be a safer option because it didn’t have offices in the United States, according to the indictment. A Web site that pitched Wegelin’s services boasted that “neither the Swiss government nor any other government can obtain information about your bank account.”

More indictments could come. The Justice Department is investigating at least 11 Swiss banks that allegedly helped Americans avoid taxes, including those that doubled down on the business after UBS ran into trouble. The department has not disclosed their identities, but according to press reports, the list includes Credit Suisse, Julius Baer, the Basel Cantonal Bank and Zurich Cantonal Bank.
