Senate Finance Committee Chairman Max Baucus (D-MT) and Finance Ranking member Charles Grassley (R-IA) sent letters to Internal Revenue Service (IRS) Commissioner Mark Everson and IRS Chief Counsel Donald Korb asking for "an updated list of the newest, biggest tax avoidance scams — including those using nonprofit groups - that deserve the committee's attention." The Senators are asking that they receive the document by April 1. The letter also referenced the IRS 2007 "Dirty Dozen", a listing of the top tax scams. On this "dirty dozen" listing was the "abuse of charitable organizations and deductions." Read the story in the Washington Post here.
