Oregon 29th District State Senator Bill Hansell says he wants to wait to see more details before taking a position on a House Democrat leadership plan to create a new business tax to help fill a budget shortfall or any other business tax overhaul proposal.  The Athena Republican does say there needs to be more of an emphasis on containing state expenditures, otherwise it will be difficult to generate any GOP votes.  House Speaker Tina Kotek and other leaders in that chamber are proposing a tax of 95-one-hundreths of a percentage point on a sales by companies with more than five million dollars in Oregon sales, while smaller businesses would pay just 250 dollars.  The trio says it would raise $2.1 billion this biennium and commit a minimum 75 percent of revenue generated through business tax reform to education.
