§68-2866. Oklahoma Tax Commission - Equalization ratio study.

A. For purposes of reporting to the State Board of Equalization the ratio derived from comparing the assessed value of the real property of each county to the full or fair cash value of such real property, the Oklahoma Tax Commission shall conduct and publish an equalization ratio study for each county annually in accordance with the requirements of this section.

B. The equalization ratio study shall be conducted in a manner that ensures:

1. the ratio of assessed value to the fair cash value of properties in a sample extracted from a county is expressed as a median of the ratios determined for all properties included in the sample;

2. sample data gathered for purposes of establishing the fair cash value of properties within the sample relates to the applicable assessment date of the study in a manner that produces reliable ratio study results;

3. sample sizes of sufficient numbers to produce an estimated ratio for a use category within a county or a ratio for an entire county at a ratio that accurately estimates the true, but unknown, assessment level;

4. appraisals selected for inclusion in the ratio study are representative of the use category or stratum of properties included in the sample;

5. sales files containing adequate information are developed and maintained for purposes of appraisals; and

6. uniformity of assessments within a use category or stratum for a county do not exceed a coefficient of dispersion value of twenty percent (20%).

C. The Oklahoma Tax Commission shall provide for a computer system that permits the equalization ratio study to be conducted pursuant to the requirements of this section. Such computer system shall be designed to permit monitoring and analysis of assessment performance in the several counties and to detect noncompliance with legal standards for valuation of taxable property in order to fulfill the duties imposed by Section 2830 of this title. The provisions of this subsection shall not be construed to authorize the Oklahoma Tax Commission to install a mainframe computer capable of remote monitoring of or making inputs into computers in the offices of the various county assessors.
