Why the rate depends on the address

An Indiana property is taxed by every unit its tax district covers: the county, the township, the city or town if it's in one, the school corporation, the library and any special districts. Merrillville 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.
