A genuinely favorable property tax rate

Custer County's effective property tax rate ran approximately 0.77%, below both the ~1.02% national median and South Dakota's own ~1.06% statewide average.

A real, disclosed rate-versus-bill tension

Custer's own home values run substantially above national and South Dakota averages, meaning the resulting DOLLAR tax bill likely runs higher than the low percentage rate alone suggests.

No state individual income tax

South Dakota levies no state individual income tax whatsoever -- a real, substantial, statewide advantage.
