For the purposes of this article:

by a state on account of the transfer or shifting of economic benefits in property at death, or in contemplation thereof, or intended to take effect in possession or enjoyment at or after death, whether denominated an “inheritance tax,” “transfer tax,” “succession tax,” “estate tax,” “death duty,” “death dues,” or otherwise.

In any case in which this state and one or more other states each claims that it was the domicile of a decedent at his or her death, at any time prior to the commencement of legal action for determination of domicile within this state or within 60 days thereafter, any executor, or the taxing official of any such state, may elect to invoke the provisions of this article. That executor or taxing official shall send a notice of that election by registered mail, receipt requested, to the taxing official of each such state and to each executor, ancillary administrator, and interested person. Within 40 days after the receipt of that notice of election, any

executor may reject that election by sending a notice, by registered mail, receipt requested, to all persons originally required to be sent a notice of election. When an election has been rejected by an executor, no further proceedings shall be had under this article. If that election is not rejected within the 40-day period, the dispute as to death taxes shall be determined solely as provided in this article. No other proceedings to determine or assess those death taxes shall thereafter be prosecuted in any court of this state or otherwise.

The determination of the board and the record of its proceedings shall be filed with the authority having jurisdiction to assess the death tax in the state determined to be the domicile of the decedent and with the authorities which would have had jurisdiction to assess the death tax in each of the other states involved if the decedent had been found to be domiciled therein.

Notwithstanding the commencement of a legal action for determination of domicile within this state or the commencement of an arbitration proceeding, as provided in Section 13830.3, the Controller may in any case enter into a written agreement with the other taxing officials involved and with the executors to accept a certain sum in full payment of any death tax, together with interest and penalties, that may be due this state; provided, this agreement fixes the amount to be paid the other states involved in the dispute, at any time before that proceeding is concluded. Upon the filing of this agreement with the authority which would have jurisdiction

to assess the death tax of this state, if the decedent died domiciled in this state, an assessment shall be made as provided in that agreement, and this assessment finally and conclusively fixes the amount of death tax due this state. If the aggregate amount payable under that agreement or under an agreement made in accordance with the provisions of Section 13830.2 to the states involved is less than the minimum credit allowable to the estate against the United States estate tax imposed with respect thereto, the executor forthwith shall also pay to this state the same percentage of the difference between that aggregate amount and the amount of that credit as the amount payable to this state under that agreement bears to that aggregate amount.

When in any case the board of arbitration determines that a decedent dies domiciled in this state, the total amount of interest and penalties for nonpayment of the tax, between the date of the election and the final determination of the board, shall not exceed 12 percent of the amount of the taxes per annum.

This article shall be applicable only to cases in which each of the states involved in the dispute has in effect therein a law substantially similar hereto. However, nothing contained in this section shall prohibit the application of this article or any part hereof where any of the other states involved in the dispute have in effect therein a law empowering the tax authority to voluntarily enter into a binding arbitration or compromise agreement and such an agreement is so entered into.
