Why the rate depends on the address

An Iowa property is taxed by every levy authority in its tax district: the county, the city or township, the school district, and others such as community colleges, hospitals, and fire or ambulance districts. Sioux City spans more than one combination of these, so this page shows each one.

Your tax bill, or your county's appraisal or assessment office, lists the units for your property.

Estimate your 2026–27 bill

Use taxable value: assessed value × the residential rollback (44.5345% for 2026–27 bills), less any exemptions. $150,000 is about a $337,000 home.
