(Salem, OR) -- The IRS and the Oregon Department of Revenue have started processing income tax returns. Oregonians are eligible for part of a one-point-four-billion dollar kicker refund. That happens when the state collects revenue that's over two percent of the budgeted amount. Due to anti-fraud measures, refunds won't start being issued until February 17th. If you file by paper instead of electronically you won't get your refund until early April, because of a delay by the IRS in getting forms to the Oregon Department of Revenue.
