Excerpts from: http://trac.syr.edu/tracirs/newfindings/current/ 74% of corporations reporting assets > $250M are not audited. The IRS since FY 2005 has cut back by a third (33 percent) the hours it spends examining their books. This has occurred even though IRS auditors uncover the largest dollar amounts of tax under-reporting in the books of these large corporations. On an hour-by-hour basis, IRS audits of all corporations show that misreported tax dollars among the giants came to $9,354 per auditor hour, eight times higher than uncovered for the small and mid-size firms. The number of the largest companies that are escaping any IRS examination at all has ballooned â up 74 percent since FY 2005. In concrete terms, this means that three out of four corporate returns reporting assets of $250 million or more last year were not audited by the IRS. In sheer numbers, IRS audits of large corporations fell from 4,693 in FY 2005 to only 3,675 in FY 2009. Even among the biggest of the big corporations â those with assets of $5 billion or more the audit rate has declined 17 percent over the last two years, from 78 per 100 returns filed in 2007 to only 64 per 100 returns during FY 2009. The dramatic collapse in the auditing of those corporations with assets of $250 million or more has occurred during a period of increasing national concerns about growing federal deficits, growing public distrust of big business and intense worry about the extent of white collar crime personified by executives like the investment adviser, Bernard Madoff. The IRS has over 13,000 revenue agents.

According to the IRS we only have 2.5M tax paying corporations paying less than 400B in taxes... How can we justify a 700B bailout? The IRS should be required to conduct a mandatory audit of all Individuals and Corporations with assets in excess of $10M.
