The answer when computed is registered as a percent. Whenever this formula is used on all property as a whole or any class with a rating above 15%, it shall be deemed unacceptable by the department.
When a county fails to meet the standards herein prescribed, the department shall notify the county assessor and governing body by June first that the county fails to meet the standards and that a reassessment program must be immediately initiated which must be completed within two (2) years from the date of the notice or unless a one-year extension is granted within the two (2) year period because of extreme circumstances. All corrections in market sales reported for the preceding calendar year must be made to the department on or before March 21st of the year in which the reassessment program is to be implemented.
A failure to implement an acceptable reassessment program by June first of the year in which implementation of the program is required will mandate an order to the county auditor to abate or reduce the assessed value of all other classes of property at the level of assessment of the real property included in the program.
