Johnson County property tax has three separate pieces

Johnson County’s assessor page lays out a useful map of the tax process. The Assessor establishes assessed values for real estate and personal property. Schools, fire districts, ambulance districts, cities, libraries, and other taxing jurisdictions set levies. The Collector prepares bills, receives payments, and distributes the money.

That means a higher bill is not always a collector problem, and a tax rate question is not always an assessor problem. Start with the part of the chain that matches the question.

For value, ownership records, parcel maps, personal property, or a certificate of non-assessment, begin with the Assessor. For paying, receipts, delinquent tax sale, or the account after a bill is issued, use the Collector. For a levy, ask which school, fire, city, or other district applies to the parcel.
