Missouri Revised Statutes Title X. Taxation and Revenue § 145.552. Recovery of estate tax from distributee, permitted when

Unless the decedent otherwise directs by will, if any part of the decedent's gross estate for federal estate tax purposes consists of property the value of which is includable in the gross estate by reason of Internal Revenue Code section 2044, the decedent's estate shall be entitled to recover from the person receiving the property the amount by which the total Missouri estate tax paid exceeds the total Missouri estate tax which would have been payable if the value of such property had not been included in the gross estate. For purposes of this section, if there is more than one person receiving the property, the right of recovery shall be against each such person, based on his pro rata share of the property received. Further, for purposes of this section, interest and penalties attributable to additional Missouri estate tax on property described in this section shall be treated as additional Missouri estate tax which the decedent's estate shall be entitled to recover in accordance with the provisions of this section.
