50 IAC 27-4-4 Frequency of ratio studies

Sec. 4. (a) A ratio study shall be conducted by the county assessor annually for the entire county for each property class and for each township in the county that has a sufficient number of valid sales within property classes to satisfy the requirements of section 6 of this rule and 50 IAC 27-5-3. (b) The department conducts independent ratio studies annually using the data contained in files submitted to the department by the counties. However, in addition to ratio studies that use the most recent calendar year sales and the subsequent January 1 assessment data, the department may perform ratio studies using the most recent calendar year sales and the prior year January 1 assessments, which are usually determined prior to the most recent calendar year sales events, as a means of monitoring sales chasing.
