The effects of tax evasion just keep  rolling in. Widespread abuse of the tax system by some wealthy taxpayers  has prompted the IRS to adjust their audit priorities. The Wall Street  Journal ran a story stating the IRS has already begun intensive examinations  through a new investigation unit. The IRS assigned its top investigators  to the Global High Wealth Industry Group and their marching orders?  Go after hedge-fund managers, investors and anyone else who might use  complicated tactics to evade their tax obligations. 
 
What does this mean? If you’re a wealthy  taxpayer, watch out! These auditors are aggressive, relentless, and  ready to dive deep into your finances.

The reviews performed so far have  been particularly harsh, say attorneys. Investors are being asked to  turn over numerous hard-to-get documents in short order. These are "the  audits from hell that your grandfather warned you about," says  Charles P. Rettig, a partner at Hochman, Salkin, Rettig, Toscher &  Perez in Beverly Hills, Calif.
The IRS unit, known as the Global  High Wealth Industry Group, was set up last year. It began conducting  audits earlier this year—but tax attorneys say the group is only recently  getting up to speed. The unit is headed by Donna Hansberry, a longtime  litigator for the tax agency who was formerly a senior legal adviser  on the IRS commissioner's staff.
Rarely has the agency conducted audits  of the wealthy and their businesses or investments in the same way as  it looks at large companies, according to advisers. Now, though, these  individual audits will be in the hands of agents who have worked on  coordinated corporate audits. Given their experience and sophistication,  according to advisers, the agents will be better at unearthing trouble.
 
Miriam L. Fisher, a tax attorney  and partner at law firm Morgan Lewis in Washington, says the audit teams  comprise "A-list examiners" drawn from around the country  who are knowledgeable and experienced with various financial products  and industries. The audits are so intensive that each team is handling  only a few right now and they aren't far along in the process, she says.
