ZIP Code 99203

ZIP code 99203, on Spokane's south side, sits comfortably in upper-middle-income territory. Households here earn a median of $104,372, and per-capita income reaches $55,835 — both well above what many Washington neighborhoods see. Homes carry a median value of $483,300, and the county's 0.84% effective property tax rate applies to that figure, so property taxes tend to run higher in dollar terms than the rate alone implies. Add Spokane's 9.10% combined sales tax, and daily purchases carry a noticeable premium. This is an affluent-leaning area where incomes and home values are strong, but the tax environment still takes a meaningful bite.
