R.I. Gen. Laws § 44-23-29 — Agreement as to amount due when domicile is in question — Adjustment for credits against federal tax

In any case in which an election is made as provided in § 44-23-28 and not rejected, the tax administrator may 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, that the agreement also fixes the amount to be paid the other
state or states. If an agreement cannot be reached and the arbitration proceeding
specified in § 44-23-30 is commenced, and thereafter an agreement is arrived at, a written agreement may
be entered into at any time before the proceeding is concluded notwithstanding the
commencement of the proceeding. Upon the filing of the agreement or duplicate of it
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 the agreement. The assessment, except as hereinafter provided, shall finally and
conclusively fix and determine the amount of death tax due this state. In the event
that the aggregate amount payable under the agreement to the states involved is less
than the maximum credit allowable to the estate against the United States estate tax
imposed with respect to the tax, the executor shall also immediately pay to the taxing
administrator that percentage of the difference between the aggregate amount and the
amount of the credit, which the amount payable to the taxing administrator under the
agreement bears to the aggregate amount.
