Ind. Code § 6-1.1-4-9
In order to maintain a just and equitable valuation of real property, the department of local government finance may adopt a resolution declaring its belief that it is necessary to reassess all or a portion of the real property located within this state. If the department of local government finance adopts a reassessment resolution and if either a township or a larger area is involved (for assessments before January 1, 2016) or one (1) or more groups of parcels under the county's reassessment plan are involved (for assessments after December 31, 2015), the department shall hold a hearing concerning the necessity for the reassessment at the courthouse of the county in which the property is located. The department of local government finance shall give notice of the time and place of the hearing in the manner provided in section 10 of this chapter. After the hearing, or if the area involved is less than a township (for assessments before January 1, 2016) or is less than one (1) group of parcels under the county's reassessment plan (for assessments after December 31, 2015), after the adoption of the resolution of the department of local government finance, the department may order any reassessment it deems necessary. The order shall specify the time within which the reassessment must be completed and the date the reassessment will become effective.
