Property Taxation


The Division of Property Taxation coordinates and administers the implementation of property tax law throughout the state and operates under the leadership of the property tax administrator, who is appointed by the State Board of Equalization (state board).In promoting equalization of property valuation for property tax purposes and providing assistance to county assessors, the division is divided into several sections:

Administrative Resources

  • Prepares and publish administrative manuals, administrative procedures and instructions;
  • Conduct seminars regarding the administrative functions of the assessors' offices, and field studies;
  • Provides statewide assistance in title conveyance, mapping, abstracting valuations, certification of values to taxing entities, and feasibility studies;
  • Investigates taxpayer complaints;
  • Responsible for various studies and reports such as the residential assessment rate study and the property tax administrator's annual report to the General Assembly and state board.
