The Treasury Inspector General for Tax Administration has released a report, Collection Actions Could Be Accelerated on Some Large Dollar Balance Due Accounts (2009-30-090):
On December 22, 2007, there were 2,454 individual taxpayers in the IRS’ potentially collectible inventory who each owed more than $1 million in taxes, penalties, and interest. While the vast majority of these individuals (2,006 of 2,454) were being actively pursued for collection, we identified 448 accounts totaling approximately $1.2 billion that were in the Queue1 (357 accounts) or that had been shelved (91 accounts).
