ZIP Code 51101

In Sioux City's 51101 ZIP code, households bring in a median of just $15,300 a year, while per-capita income sits at $21,580 — a gap that shapes how property taxes land here. The county's 1.45% effective rate applies to whatever a home is worth, so even a lower-priced house can absorb a meaningful share of earnings at these income levels. Sales tax adds 7.00% to purchases, trimming spending power further. Together, the property tax rate and the area's low household earnings create real pressure, since each dollar of home value carries a cost that stretches a tight annual budget.
