(b) If any property in the decedent's estate is located outside of Washington, the amount of tax is the amount determined in (a) of this subsection multiplied by a fraction. The numerator of the fraction is the value of the property located in Washington. The denominator of the fraction is the value of the decedent's gross estate. Property qualifying for a deduction under RCW 83.100.046 must be excluded from the numerator and denominator of the fraction.
(3) The tax imposed under this section is a stand-alone estate tax that incorporates only those provisions of the internal revenue code as amended or renumbered as of January 1, 2005, that do not conflict with the provisions of this chapter. The tax imposed under this chapter is independent of any federal estate tax obligation and is not affected by termination of the federal estate tax.

Dep't of Rev., Docket No. 74974-4, that Washington's estate tax is tied to the current federal Internal Revenue Code. The legislature finds that the revenue loss resulting from the Hemphill decision will severely affect the legislature's ability to fund programs vital to the peace, health, safety, and support of the citizens of this state.
