The Auditor's Office maintains records of current property ownership within Johnson County for taxation purposes. These records are available to the public and consist of plat maps showing current ownership, aerial photos showing ground cover and other physical attributes, and road maps. Each year the Auditor's Office compiles property tax levies and calculates property taxes, which are collected by the Treasurer's Office.
