WASHINGTON (Reuters) - The 500 largest American companies hold more than $2.1 trillion in accumulated profits offshore to avoid U.S. taxes and would collectively owe an estimated $620 billion in U.S. taxes if they repatriated the funds, according to a study released on Tuesday.
The study, by two left-leaning non-profit groups, found that nearly three-quarters of the firms on the Fortune 500 list of biggest American companies by gross revenue operate tax haven subsidiaries in countries like Bermuda, Ireland, Luxembourg and the Netherlands.
Citizens for Tax Justice and the U.S. Public Interest Research Group Education Fund used the companies' own financial filings with the Securities and Exchange Commission to reach their conclusions.
Technology firm Apple was holding $181.1 billion offshore, more than any other U.S. company, and would owe an estimated $59.2 billion in U.S. taxes if it tried to bring the money back to the United States from its three overseas tax havens, the study said.
The conglomerate General Electric has booked $119 billion offshore in 18 tax havens, software firm Microsoft is holding $108.3 billion in five tax haven subsidiaries and drug company Pfizer is holding $74 billion in 151 subsidiaries, the study said
