It’s been well documented that major U.S. multinational corporations are stockpiling profits offshore to avoid U.S. taxes. Congressional hearings over the past few years have raised awareness of tax avoidance strategies of major technology corporations such as Apple and Microsoft, but, as this report shows, a diverse array of companies are using offshore tax havens, including the pharmaceutical giant Amgen, apparel manufacturers Levi Strauss and Nike, the supermarket chain Safeway, the financial firm American Express, banking giants Bank of America and Wells Fargo, and even more obscure companies such as Advanced Micro Devices and Symantec.
All told, American Fortune 500 corporations are avoiding up to $695 billion in U.S. federal income taxes by holding $2.4 trillion of “permanently reinvested” profits offshore. In their latest annual financial reports, 27 of these corporations reveal that they have paid an income tax rate of 10 percent or less in countries where these profits are officially held, indicating that most of these monies are likely in offshore tax havens.
