About two-thirds of U.S. companies and foreign firms doing business in this country paid no federal income taxes from 1998 to 2005, according to a study by the Government Accountability Office. Sen. Byron Dorgan, D-N.D., called the report "a shocking indictment of the current tax system."
But the report said that about a quarter of large corporations - ones that had more than $250 million in assets or $50 million in gross receipts - paid no taxes. In 2005, for instance, 3,565 large U.S. companies and 998 large foreign-owned companies operating here did not pay any income taxes.
