Mo. Rev. Stat. § 137.079
Prior to setting its rate or rates as required by section 137.073, each taxing authority shall exclude from its total assessed valuation seventy-two percent of the total amount of assessed value of* business personal property that is the subject of an appeal at the state tax commission or in a court of competent jurisdiction in this state. This exclusion shall only apply to the portion of the assessed value of business personal property that is disputed in the appeal, and shall not exclude any portion of the same property that is not disputed. If the taxing authority uses a multirate approach as provided in section 137.073, this exclusion shall be made from the personal property class. The state tax commission shall provide each taxing authority with the total assessed value of business personal property within the jurisdiction of such taxing authority for which an appeal is pending no later than August twentieth of each year. Whenever any appeal is resolved, whether by final adjudication or settlement, and the result of the appeal causes money to be paid to the taxing authority, the taxing authority shall not be required to make an additional adjustment to its rate or rates due to such payment once the deadline for setting its rates, as provided by this chapter, has passed in a taxable year, but shall adjust its rate or rates due to such payment in the next rate setting cycle to offset the payment in the next taxable year. For the purposes of this section, the term "business personal property" means tangible personal property which is used in a trade or** business or used for production of income and which has a determinable life of longer than one year except that supplies used by a business shall also be considered business personal property, but shall not include livestock, farm machinery, property subject to the motor vehicle registration provisions of chapter 301, property subject to the tables provided in section 137.078, the property of rural electric cooperatives under chapter 394, or property assessed by the state tax commission under chapters 151, 153, and 155, section 137.022, and sections 137.1000 to 137.1030.
