Nebraska Tax Records
From Ancestry.com Wiki
Many tax records are still held at the county level; many taken before 1912 have been sent to the Nebraska State Historical Society. The society is continually collecting county records. At present they have tax records for about half of the counties and assessment records for many others, all for various periods of time. The researcher should contact the Public Records at the Nebraska State Historical Society to learn of its holdings for a particular county before contacting the county. County tax records, real and personal, are located in the office of the county treasurer at the county seat.
