ZIP Code 53203

ZIP code 53203, which falls in Milwaukee, sits in solidly middle-to-upper-income territory for the area, with a median household income of $86,159 and per-capita income of $79,234. That earning power comes alongside a county-level effective property tax rate of 1.93%, so owners here hand over a meaningful share of their property's value each year. Add a combined sales tax of 7.90% on purchases, and the overall tax picture carries real weight. Households earning at this level can absorb those costs, but the cumulative effect of property and sales taxes still shapes day-to-day spending in this part of Milwaukee.
