US corporate giants such as Apple, Walmart and General Electric have stashed $1.4tn (£980bn) in tax havens, despite receiving trillions of dollars in taxpayer support, according to a report by anti-poverty charity Oxfam.
The sum, larger than the economic output of Russia, South Korea and Spain, is held in an “opaque and secretive network” of 1,608 subsidiaries based offshore, said Oxfam.
The charity’s analysis of the financial affairs of the 50 biggest US corporations comes amid intense scrutiny of tax havens following the leak of the Panama Papers.
And the charity said its report, entitled Broken at the Top was a further illustration of “massive systematic abuse” of the global tax system.
Technology giant Apple, the world’s second biggest company, topped Oxfam’s league table, with some $181bn held offshore in three subsidiaries.
