When the Department of Revenue and the taxing official of one or more other states each claims that the state of that official respectively was the domicile of the decedent for the purpose of estate taxes or claims taxing authority over the same property in an estate, the department may negotiate, and enter into an agreement, with the taxing official of the other state and with the executor to accept payment of estate tax, together with any interest and penalties. The department may enter into binding arbitration or into a compromise agreement with respect to disputed liability for estate taxes with each taxing official and with the executor.
