"" [Thomson Reuters interview]:  A new IRS unit set up to catch rich tax cheats hiding their wealth in complex business entities is rapidly taking shape with the hiring of hundreds of employees. An IRS official told Thomson Reuters "hundreds" of people have already been hired to staff the new unit, including some from within the agency. "We have drawn top talent within the IRS that have expertise involving wealthy individuals as well as examination of their related entities," said Mae Lew, an IRS special counsel. The high-wealth unit is focusing on trusts, real estate investments, privately held companies and other business entities controlled by rich individuals. While use of sophisticated legal structures can be legal, in other instances they "mask aggressive tax strategies," IRS Commissioner Doug Shulman said. Tax authorities in Japan, Germany and the UK have also created similar units. The U.S. House of Representatives on Thursday approved a $387 million boost for the IRS for the fiscal year that started October 1, in part to fund the high-wealth unit. The Senate is expected to vote on the measure on Sunday.

The IRS is also opening new criminal offices in Beijing, Panama City and Sydney to focus on funds flowing out of Europe and into Asia, in part because of a heightened focus on international enforcement in Europe. The goal is to get those up and running during this fiscal year, which ends September 30, according to Barry Shott, IRS deputy commissioner for international issues for large and midsized business. At the center of the agency's offshore effort is its legal cases against Swiss banking giant UBS AG. UBS agreed to turn over nearly 5,000 names of individual American clients and paid $780 million to settle a criminal case for aiding tax evasion. The IRS has also begun initial steps to join forces with other governments to scrutinize corporate tax filings to prevent "tax arbitrage" by companies seeking the best regime.

Some tax practitioners expressed worry about such coordination. "With any new thing, you never want to be the guinea pig," Mary Lou Fahey, general counsel for the Tax Executive Institute, comprised of business executives, said. Shott said a likely scenario will likely be two countries getting together and decide to examine a narrow issue. In the beginning it will operate like a pilot program where the corporation examined would agree to take part. "With rare exception ... the taxpayer will absolutely know they are subject to a simultaneous examination," Shott said. Still, he said there could be cases where the audit needs to be kept quiet, such as when a criminal probe is ongoing. Initial partners would likely include Canada, the UK and Australia, Shott said.
