About Property Taxes in Dewey County, South Dakota
Dewey County's highest rate among peers
Dewey County's effective tax rate of 1.338% is among the highest nationally, surpassing the U.S. median of 0.84% by a significant margin. However, the median tax bill of just $1,009 remains far below the national median of $2,690, due to very modest median home values of only $75,400.
South Dakota's steepest tax rate
Dewey County leads South Dakota with an effective tax rate of 1.338%, well above the state average of 1.094%. Despite this high rate, the modest median home value of $75,400 means residents pay only $1,009 in median annual taxes.
Highest rate in the regional comparison
Dewey County (1.338%) has the highest effective tax rate among all its peer counties, exceeding Davison (1.243%), Fall River (1.064%), and others in the dataset. The $1,009 median tax remains affordable only because home values are substantially lower.

A homeowner with Dewey County's median property value of $75,400 pays approximately $1,009 per year in property taxes at the 1.338% rate. That's about $84 monthly—low in absolute dollars, but the county applies the steepest rate per dollar of value.
High rates make assessments worth checking
With Dewey County's steep 1.338% effective rate, even small errors in property assessment compound quickly. If your home was recently assessed higher than comparable nearby sales, a formal appeal could yield meaningful savings.
