Each year, major corporations and individuals avoid as much as $100 billion a year in federal taxes by “off-shoring” the money they make here in the U.S. or by setting up sham headquarters in tax haven countries. Taxpayers are left footing the bill. According to "Tax Shell Game: What Do Tax Dodgers Cost You?" a new Texas Public Interest Research Group (TexPIRG) report, this results in an average of $500 in additional tax burden for taxpayers. Here in Texas, it’s $539 per taxpayer.
