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. All of Columbia Township shares the same combination.

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