W.S. § 39-19-103 — Imposition of tax

(a) Taxable event. A tax is imposed on the transfer of
property constituting the Wyoming gross estate of every
decedent.
(b) Basis of tax. The amount of tax is the maximum state
death tax credit allowed to a Wyoming estate as a credit against
federal estate taxes under the laws of the United States for
estate, inheritance, legacy and succession taxes actually paid
to the several states times the ratio which the Wyoming gross
estate bears to the value of the federal gross estate, or the
maximum state death tax credit allowable to a Wyoming gross
estate, whichever is greater. W.S. 39-19-101 through 39-19-111
are intended to take full advantage for Wyoming of the credit
which is allowed as a deduction from the federal estate tax
liability of estates of decedents, for state taxes upon property
or transfer thereof by reason of death, without increasing the
aggregate of federal and state death, transfer or succession
taxes upon any estate.
(c) Taxpayer. The personal representative of an estate, a
portion of which constitutes Wyoming gross estate, shall file
with the department a duplicate of all federal estate tax
returns and notices required to be made to the federal
authorities and pay the Wyoming estate tax to the department.
Any tax liability under W.S. 39-19-101 through 39-19-111
becomes, from the time the tax liability is due and payable, a
debt of the taxpayer to the state, to be recovered in an action
on this title. The attorney general may bring an action at the
request of the department in the name of the state to collect
any tax liability of any taxpayer under W.S. 39-19-101 through
