Cardinal Health Exposed by Tax Whistleblower

UBS was the first big tax whistleblower case to hit the press.  Cardinal Health has the dubious distinction of being the second.  The IRS is pursuing Cardinal Health for $777 million in unpaid tax plus interest and penalties.  The unpaid tax stems from an international tax shelter facilitated by Rabobank Group, a Dutch bank that has been involved in numerous controversial tax arrangements.  The systematic underreporting of tax was exposed by a former Rabobank executive who exposed his former employer and Cardinal Health.  Cardinal Health announced the situation in a securities statement in May 2009.
