Sidley Austin Brown & Wood

Major accounting firms, banks, law firms and investment advisors helped create "abusive tax shelters" that deprived the United States Government of "billions of dollars", it has been claimed. Among the alleged participants were KPMG, Ernst & Young, PricewaterhouseCoopers, Sidley Austin Brown & Wood, Sutherland Asbill & Brennan, Deutsche Bank, HVB, UBS, First Union National Bank, Wachovia Bank, Presidio and Quellos.

The investigation by the IRS into alleged offshore tax evasion by United States taxpayers using offshore credit cards appears to be currently focusing on Antigua & Barbuda, the Bahamas, and the Cayman Islands. Although the IRS has previously announced it is targeting more than 30 offshore centers, these three are the only countries to feature in a slew of "John Doe" summonses issued recently by U. S. federal courts.
