Offshore tax havens cost taxpayers revenue totaling as much as $100 billion per year -
$1 trillion over 10 years. Individuals and corporations based in the U.S. who pay taxes
on their revenues must shoulder this burden for those who do not.4

executive summary:
Each year, the United States loses an estimated $100 billion in tax revenues due to
offshore tax abuses.1 Offshore tax havens today hold trillions of dollars in assets provided by
citizens of other countries, including the United States.2 The extent to which those assets
represent funds hidden from tax authorities by taxpayers from the United States and other
countries outside of the tax havens is of critical importance.3 A related issue is the extent to
which financial institutions in tax havens may be facilitating international tax evasion.

1 This $100 billion estimate is derived from studies conducted by a variety of tax experts. See, e.g., Joseph
Guttentag and Reuven Avi-Yonah, “Closing the International Tax Gap,” in Max B. Sawicky, ed., Bridging the Tax
Gap: Addressing the Crisis in Federal Tax Administration (2006) (estimating offshore tax evasion by individuals at
$40-$70 billion annually in lost U.S. tax revenues); Kimberly A. Clausing, “Multinational Firm Tax Avoidance and
U.S. Government Revenue” (August 2007) (estimating corporate offshore transfer pricing abuses resulted in $60
billion in lost U.S. tax revenues in 2004); John Zdanowics, “Who’s watching our back door?” Business Accents
magazine, Volume 1, No.1, Florida International University (Fall 2004) (estimating offshore corporate transfer
pricing abuses resulted in $53 billion in lost U.S. tax revenues in 2001); “The Price of Offshore,” Tax Justice
Network briefing paper (March 2005) (estimating that, worldwide, individuals have offshore assets totaling $11.5
trillion, resulting in $255 billion in annual lost tax revenues worldwide); “Governments and Multinational
Corporations in the Race to the Bottom,” Tax Notes (2/27/06); “Data Show Dramatic Shift of Profits to Tax
Havens,” Tax Notes (9/13/04). See also series of 2007 articles authored by Martin Sullivan in Tax Notes
(estimating over $1.5 trillion in hidden assets in four tax havens, Guernsey, Jersey, Isle of Man, and Switzerland,
beneficially owned by nonresident individuals likely avoiding tax in their home jurisdictions), infra footnote 3.
