(1) For the purposes of determining the Washington taxable estate, a deduction is allowed from the federal taxable estate for:
(a) The value of qualified real property reduced by any amounts allowable as a deduction in respect of the qualified real property under 26 U.S.C. Sec. 2053(a)(4) of the federal internal revenue code, if the decedent was at the time of his or her death a citizen or resident of the United States.
(b) The value of any tangible personal property used by the decedent or a member of the decedent's family for a qualified use on the date of the decedent's death, reduced by any amounts allowable as a deduction in respect of the tangible personal property under 26 U.S.C.

(b) The property is acquired by any person from the estate; or
(c) The property is acquired by any person from a trust, to the extent the property is includible in the gross estate of the decedent.
(3) If the decedent and the decedent's surviving spouse at any time held qualified real property as community property, the interest of the surviving spouse in the property must be taken into account under this section to the extent necessary to provide a result under this section with respect to the property which is consistent with the result which would have obtained under this section if the property had not been community property.
(4) In the case of any qualified woodland, the value of trees growing on the woodland may be deducted if otherwise qualified under this section.
(5) If property is qualified real property with respect to a decedent, hereinafter in this subsection referred to as the "first decedent," and the property was acquired from or passed from the first decedent to the surviving spouse of the first decedent, active management of the farm by the surviving spouse must be treated as material participation by the surviving spouse in the operation of the farm.
(6) Property owned indirectly by the decedent may qualify for a deduction under this section if owned through an interest in a corporation, partnership, or trust as the terms corporation, partnership, or trust are used in 26 U.S.C. Sec. 2032A(g) of the federal internal revenue code. In order to qualify for a deduction under this subsection, the interest, in addition to meeting the other tests for qualification under this section, must qualify under 26 U.S.C.

(b) For the purposes of (a) of this subsection, an individual is disabled if the individual has a mental or physical impairment which renders that individual unable to materially participate in the operation of the farm.
(8) Property may be deducted under this section whether or not special valuation is elected under 26 U.S.C. Sec. 2032A of the federal internal revenue code on the federal return. For the purposes of determining the deduction under this section, the value of property is its value as used to determine the value of the gross estate.
(9)(a) In the case of any qualified replacement property, any period during which there was ownership, qualified use, or material participation with respect to the replaced property by the decedent or any member of the decedent's family must be treated as a period during which there was ownership, use, or material participation, as the case may be, with respect to the qualified replacement property.
