South Dakota Tax Records
From Ancestry.com Wiki
Most tax lists that have survived are housed at the county seat in the auditor’s office. A few early tax records have been microfilmed and remain at the South Dakota State Historical Society, including those of “Old Stanley County,” comprised of present-day Stanley, Haakon, and Jackson counties. The microfilms for tax records are not always easy to read, but can include county commissions work in selecting juries, docket books, and real and personal property taxes. Others at the archives include Huron; Beadle County (1883–1902); Edmunds (1887–1924); Roberts (1884–1929); Stanley (1891–1930); Union (1870–1901); and delinquent tax lists from Walworth (before 1899).
