The IRS has released its annual Data Book, 2011, which it describes as follows:  “This report describes activities conducted by the Internal Revenue Service during Fiscal Year 2011 (October 1, 2010, through September 30, 2011).  It provides information on returns filed and taxes collected, enforcement, taxpayer assistance, the IRS budget and workforce, and other selected activities.”

As seen on page 22 of the report, what many may find interesting is that, of 140,837,499 individual income tax returns filed last year, 1,564,690 (or 1.1%) were examined by the IRS.
