ZIP Code 57767

ZIP code 57767, near Rapid City, ranks among the wealthiest areas in the country, with a median household income of $250,001 and per-capita income of $96,547. That places it firmly in affluent territory. Property taxes run at 1.01% of value at the county level, a rate that applies to high-value homes and can translate into substantial annual bills despite the seemingly low percentage. The combined sales tax rate of 4.20% is comparatively restrained, so everyday purchases carry less of a premium than the income level might imply.
