IRS chief says offshore abuses a problem
By MARY DALRYMPLE, AP Tax Writer 1 hour, 55 minutes ago
WASHINGTON - IRS Commissioner Mark Everson told senators Tuesday that a trend toward a world economy helps wealthy taxpayers hide money in complicated transactions offshore, virtually invisible to tax agents.
"We have real difficulties finding out what's going on," he said. "Our challenges are acute and ever-growing. Offshore abuses are a real problem."
Everson testified to the investigative subcommittee of the Senate
Homeland Security and Governmental Affairs Committee, which concluded a yearlong study of offshore tax shelters. They concluded that offshore tax havens allow the wealthy to stash trillions of dollars, mostly impervious to tax, regulatory and law enforcement authorities.
The panel said the havens allow Americans to avoid paying $40 billion to $70 billion in taxes each year, with the help of "an armada" of professional advisers.
