ZIP Code 60603

ZIP code 60603 sits in downtown Chicago, where a median household income of $133,545 and per-capita income of $100,340 place it firmly in affluent territory. Homes here carry a median value of $633,900, and Cook County's 1.91% effective property tax rate translates into a substantial annual bill on that valuation. Add Chicago's combined sales tax of 10.25%, among the highest in the nation, and the cost of living climbs further. High earnings accompany high taxes across every category, so this ZIP's prosperity comes with a correspondingly heavy fiscal load.
