Apple has set up three foreign subsidiaries that the company claims are not resident in any nation for taxing purposes, in an effort to avoid paying tens of billions of dollars in taxes to the U.S. and other countries, according to a new report from a U.S. Senate subcommittee. Apple has set up a "complex web" of offshore entities to avoid paying taxes, with some subsidiaries set up in low-tax Ireland, according to a report released Monday by the investigations subcommittee of the Senate Homeland Security and Governmental Affairs Committee.
