Interstate arbitration of death taxes
Wis. Stat. § 72.35
in effect(1) Arbitration agreement. When the department and the taxing authority of another state each claim that a decedent was a resident of its state on the date of the decedent’s death, the department may make a written agreement with the other taxing authority and with the personal representative, special administrator or trustee, to settle the dispute or submit the controversy to a panel consisting of any uneven number of arbitrators. Parties to the agreement shall select the arbitrators.
(2) Powers of the panel. The panel may administer oaths, take testimony and subpoena witnesses and the production of books, papers and documents. Subpoenas may be issued by any panel member. When a person fails to obey a subpoena, any court of record of this state, upon application by the panel, may order compliance with the subpoena and may punish further failure to obey as contempt.
(3) Hearings. The panel shall hold hearings at such times and places as it may determine, upon reasonable notice to the parties to the agreement, all of whom may be heard, present evidence and examine and cross-examine witnesses.
(4) Majority vote. Except when issuing subpoenas, all questions arising in the course of the proceedings shall be determined by majority vote of the panel.
(5) Determination of residence. The panel, by majority vote, shall determine the residence of the decedent on the date of the decedent’s death. This determination shall be final only for purposes of imposing and collecting death taxes.
(6) Filing of documents. The panel shall file with each party to the agreement in sub. (1) and with the circuit court having jurisdiction under s. 72.27 a certified copy of:
(a) The agreement;
(b) The record of the panel’s proceedings; and
(c) The panel’s determination.
(7) Compromise by parties. The department may at any time enter into a written agreement to settle the controversy made under sub. (1) fixing the amounts to be accepted by the parties in full satisfaction of death taxes.
(8) Compensation and expenses. Compensation and expenses of members of the panel and its employees shall be agreed upon among the members and the personal representative, special administrator or trustee. If they cannot agree, compensation and expenses shall be fixed by the court which has or would have probate jurisdiction in the state determined by the board to be the residence of decedent. The amounts agreed upon or fixed shall be an administration expense and shall be payable out of property transferred.
