Offshore Tax Crimes Scorecard: Bankers, Clients at UBS

The U.S. extended its crackdown on offshore tax evasion, charging former UBS AG banker Renzo Gadola with helping American clients hide assets from the Internal Revenue Service by shifting them to a smaller Swiss bank.

Gadola, 44, was accused yesterday of conspiring with a Swiss banker to encourage U.S. clients who hadn’t told the IRS about their UBS accounts to open undeclared accounts at Basler Kantonalbank. Gadola and the banker told clients not to join a voluntary disclosure program that led 18,000 Americans to declare offshore accounts to the IRS, prosecutors said.
