The Tax Foundation offers a useful debunking of a new report on corporate taxes that was issued by Citizens for Tax Justice and the U.S. Public Interest Research Group. The report was the subject of a remarkably and disappointingly unskeptical column in the Times by Floyd Norris that ran under the headline "The Islands Treasured by Offshore Tax Avoiders." In addition to the points made by the Tax Foundation that were omitted from Mr. Norris's column, it's worth mentioning that CTJ and U.S. PIRG are both tax-exempt themselves.
