The Oregon Department of Revenue wants to improve their efforts to get your tax money, but, a computer system upgrade probably won't happen anytime soon.  The Oregon Department of Revenue received some unwanted attention when a worker accidentally approved a fraudulent $2-million refund. A review of the Revenue Department's work highlighted the state agency's need for a new computer system; but the Statesman Journal reports that upgrade isn't likely to happen until 2015. The Department has asked the Governor for the $4-million in direct funds needed for the upgrade.  That would require approval by the Legislature and, in recent years and the upcoming session, money is more than tight, with very little available for technology upgrades.
