Missouri Revised Statutes Title X. Taxation and Revenue § 145.871. Reciprocity with other states in enforcement of liabilities for estate and transfer taxes

The courts of this state shall recognize and enforce liabilities for estate and transfer taxes lawfully imposed by any state which extends a like comity to this state, and the duly authorized officer of any such state may sue for the collection of such a tax in the courts of this state. A certificate by the secretary of state of the other state that an officer suing for the collection of the tax is duly authorized to collect the tax shall be conclusive proof of such authority. For the purposes of this section, the word “TAXES” shall include additions to tax, interest, and penalties, and liabilities for the taxes, additions to tax, interest, and penalties shall be recognized and enforced by the courts of this state to the same extent that the laws of the other state permit the enforcement in its courts of liability for the taxes, additions to a tax, interest, and penalties due this state under sections 145.011 to 145.995.
