Lincoln city officials have taken three cell phone providers to court for not paying millions of dollars in taxes.
Cell service provider Verizon has paid the city $1.7 million in additional occupation taxes. In a separate case, Windstream paid the city $2.4 million.
A third case still in federal court involves Sprint PCS.
City attorney Steve Huggenberger says an audit three years ago discovered the providers had not paid a 6 percent occupation tax in full.
Lincoln says Sprint PCS owes about $800,000 for the years 2005 to 2009.
Phone companies paid Lincoln $8.5 million dollars in taxes in 2011.
Omaha received $14.9 million, but city finance director Pam Spaccarotella says the city has not conducted the same kind of audit.
