PURPOSE: This rule explains when a taxpayer may ask the commission to review a local assessment of real property.

1. (1) For the purpose of appeal under 12 CSR 30-3.010, each year’s tax assessment shall constitute a separate cause of action which the taxpayer may appeal. The value of the subject property will be determined by the method set out in 12 CSR 30-3.001.

2. (2) Except as set in section (3), the taxpayer shall be allowed to litigate the issue of the assessed valuation of the subject property only once in each two (2)-year assessment cycle established by section 137.115, RSMo. The assessed value established by the commission for the odd-numbered year also shall be the assessed value for the following even-numbered year.

   1. (A) The commission shall determine the appropriate assessed value of the subject property based on economic conditions present in the market on January 1 of the odd-numbered year and shall resolve all issues presented in the appeal for the odd-numbered year.
   2. (B) Except in those instances in section (3) when the taxpayer is allowed to litigate the issue of assessed value in the even-numbered year, the commission shall rule summarily on the appeal filed for the even-numbered year using the assessed value so established for the previous odd-numbered year.

3. (3) The taxpayer may be allowed to litigate the issue of assessed valuation of the subject property more than once in each two (2)-year assessment cycle if a verified statement filed with his/her appeal states facts which demonstrate that the commission should reconsider the appropriateness of the valuation. Facts which demonstrate that the appropriateness of the valuation should be reconsidered are—

   1. (A) When the assessor or board of equalization should have decreased the assessed value of the subject property for January 1 of the even-numbered year in the two (2)-year assessment cycle pursuant to 12 CSR 30-3.001, but failed to do so; or
   2. (B) When the assessor or board of equalization raises the assessed value of the subject property for January 1 of the even-numbered year in the two (2)-year assessment cycle pursuant to 12 CSR 30-3.001.

4. (4) A taxpayer who fails to appeal the assessed value in the odd-numbered year does not waive his/her right to appeal the assessed value in the even-numbered year. Any decision on the appeal of the assessment for the even-numbered year shall affect only the even-numbered year’s assessment.
