For those of you who don't want to go through the trouble of tracking down the unredacted full article, here're the nut grafs:<p><i>The U.S. has been rewarding people who turn in fellow citizens or companies defrauding government programs since Congress's passage of the False Claims Act in 1863. Whenever there has been an income tax—briefly during the Civil War, and permanently since 1913—the IRS (or its predecessor) has had its own whistleblower program, says tax historian Joseph Thorndike of Tax Analysts, a nonprofit publisher. But payments tended to be small and rare because IRS officials were uncomfortable with "bounty hunting."</i><p><i>The landscape changed in 2006. Heartened by the success of a whistleblower program for nontax issues such as government contracts, Congress overhauled the special tax provisions on whistleblowers and set up the IRS's large-award program.</i><p>The IRS does not want your tax-cheating neighbor, but if you work for a company that is cheating the government out of <i>tens of millions of dollars</i>, I think we <i>all</i> want you to act.
