(1) A tax is imposed on each generation-skipping transfer, other than a direct skip, occurring at the same time and as a result of the death of an individual, in an amount equal to the maximum federal credit allowable under section 2604, Internal Revenue Code.
(2) If any of the property transferred is real property in another state or personal property located in another state that requires the payment of a tax for which credit is received against the federal generation-skipping transfer tax, the tax due under subsection (1) must be reduced by an amount that bears the same ratio to the total state tax credit allowable for federal generation-skipping transfer tax purposes as the value of the property taxable in the other state bears to the value of the gross generation-skipping transfer for federal generation-skipping transfer tax purposes.
