(Salem, OR) -- If you filed your tax return electronically with the State of Oregon, and you're getting a refund, the money could be on the way. The Oregon Department of Revenue has processed 500 thousand returns that were filed electronically. Most refunds will be issued in about two weeks. Some returns that require additional review can take up to five months. Tax returns filed on paper won't begin to be processed in Oregon until the end of March, due to a delay in communication from the IRS. Those refunds will start going out in April.
