Amgen Inc. has been hit by a bill of more than $ 7 billion in unpaid taxes and fines from the Internal Revenue Service, the company said Wednesday, the latest salvo in the company’s dispute over residual taxes related to its activities in Puerto Rico.
Amgen said it received a statement from the IRS on April 18 seeking to increase Amgen’s federal taxes by $ 5.1 billion plus interest and $ 2 billion in fines for the years 2013 to 2015.
