# (2)
(2) Estates of decedents who die on or after July 1, 2023, may claim the exemption under ORS 118.145 only for natural resource property located in Oregon.
# (3)
(3) An exemption under ORS 118.145 may be claimed for natural resource property held by an eligible entity. The eligible entity must qualify as an eligible business entity or eligible trust. The eligible entity may hold the natural resource property directly or indirectly through another eligible entity. The value of an eligible entity is included in the exemption only to the extent the value of the eligible entity is attributable to natural resource property used in a farm, fishing or forestry business owned by the entity.
# (4)
(4) Transfer of ownership of natural resource property, which includes an interest in an eligible entity for purposes of this paragraph, between qualifying family members and eligible entities does not cause natural resource property to lose its eligibility for exemption under ORS 118.145 if all other requirements of ORS 118.145 and this rule continue to be met. If an interest in natural resource property is transferred by a qualified family member or an eligible entity to a qualified family member or an eligible entity, the interest in natural resource property shall be deemed to have been owned by the transferee during the time that the interest in natural resource property was owned or deemed to have been owned by the transferor.
# (5)
(5) Material participation.
(a) To qualify under ORS 118.145, the decedent or a qualifying family member of the decedent must materially participate in the management of the business associated with the natural resource property. The duties of material participation may not be delegated to a person who is not a qualifying family member, except when the qualifying family member is an eligible qualified heir as defined by IRC 2032A(c)(7)(C), as in effect on December 31, 2010, in which case the material participation duties may be delegated to a fiduciary of the eligible qualified heir.
(b) The decedent or qualifying family member(s) must materially participate by engaging in active management of the farming, forestry, or fishing business for at least 75 percent of the relevant business days during the calendar year, or for qualifying small forestland owners, for the entire year as defined in 5(c) of this rule.
(c) A small forestland owner is not subject to the requirement to materially participate for at least 75 percent of the relevant business days during the calendar year. A small forestland owner must actively manage the small forestland property through appropriate or customary silvicultural or management activities given the current phase in the forest management cycle for the small forestland property. A small forestland owner must maintain documentation of these silvicultural or management activities. This paragraph applies to estates of a decedent who dies on or after January 1, 2026.
(d) Material participation by a decedent and each qualifying family member is evaluated separately for each family member and may not be combined for purposes of determining the percentage under subsection (b) of this section. However, more than one family member may materially participate at any given time.
(e) Disqualification for failure to meet material participation requirements in a calendar year shall not occur if the failure to meet material participation requirements in the calendar year is due to the death or disability, as defined in IRC 2032A(b)(4)(B), of a qualifying family member.
(f) Active management decisions that demonstrate material participation include, but are not limited to, the following: inspecting growing crops, animals, on-going fishing operations, forests, or equipment; reviewing and approving annual crop plans in advance of planting; making a substantial number of the management decisions of the business operation; approving expenditures for other than nominal operating expenses in advance of the time the amounts are expended; deciding what crops to plant or how many cattle to raise; determining what fields to leave fallow; determining what kind of fish to harvest and the equipment needed to harvest the fish; determining where and when to market crops and other business products; determining how to finance business operations; and determining what capital expenditures the trade or business should make.
(g) A disposition of the natural resource property occurs if the material participation requirements are not met. Whether the material participation requirement has been met for a calendar year will be determined at the end of the calendar year. If the material participation requirement is not met during the calendar year, the disposition of the natural resource property is deemed to occur December 31 of the calendar year in which the disposition occurs.
(h) The decedent or qualifying family member must maintain documentary evidence of all decisions described by IRC 2032A(e)(12) related to the conduct of the natural resource business. The documentary evidence should record the involvement of the decedent or qualifying family member. Examples of documentary evidence of decision-making include, but are not limited to, the following: a contemporaneous log, contemporaneous business communication, contracts, legal documents, contemporaneous minutes, and statements related to the natural resource business made under oath in a court of law. Documentary evidence of material participation may be evaluated with reference to industry standards to determine if the material participation requirement has been met.
# (6)
(6)(a) Natural resource property previously used as a basis to claim the exemption under ORS 118.145 may be replaced with other natural resource property and not result in a disposition subject to additional tax, subject to following other applicable statutory requirements and the following:
(A) If the relinquished property is real property, the replacement property must be real property acquired within one year of the transfer of the relinquished property, or within two years of the transfer in the case of property that is involuntarily converted within the meaning of section 1033 of the Internal Revenue Code;
(B) Personal property is considered replaced by other natural resource property by holding and using the proceeds from the sale of personal property in an operating allowance as described in ORS 118.140(1)(j) and subject to the limitation at ORS 118.140(2)(a), or by acquiring other natural resource property within 180 days of the transfer of the relinquished property
(C) the replacement property must qualify as natural resource property and must be used in the farming, forestry or fishing business promptly after its acquisition.
(b) If the purchase price of the replacement property is less than the gross sales price of the relinquished property less selling expenses (net sales proceeds), the amount that is treated as a disposition subject to additional tax is the gross sales price multiplied by a fraction that is equal to the difference between the net sales proceeds and the purchase price of the replacement property, divided by the net sales proceeds. Gross sales include any amount of money and fair market value of property received, as defined by IRC 1011(b) and associated regulations in effect on January 1, 2026, from the sale of or other disposition of property.
(c) To the extent that the replacement is not treated as a disposition subject to additional tax, the replacement property shall be deemed to have been owned by the transferor during the time that the transferred property was held or deemed to have been owned by the transferor, regardless of whether the transfer occurs before or after the death of the decedent.
# (7)
(7) The value of the exemption allowed under ORS 118.145 must be excluded from the numerator and denominator of the ORS 118.010(5) and (6) apportionment calculations.
# (8)
(8)(a) A person who inherits an interest in natural resource property from the decedent or is a recipient of a transfer of an interest in natural resource property from a qualifying family member must attest, on a form prescribed by the department, that the person acknowledges and understands the requirements prescribed by ORS 118.145 and this rule to claim the natural resource property exemption.
(b) The owner of the natural resource property at the time of the disposition or disqualifying event must pay any additional tax owing if the requirements for exemption under ORS 118.145 and this rule are no longer met.
(c) A qualifying family member must file a report each year on a form prescribed by the department reporting whether the exemption requirements under ORS 118.145 and this rule continue to be met during the relevant five-year period.
# (9)
(9) The amendments to this rule effective on January 1, 2026, except as stated in paragraph 5(c), apply to estates of decedents dying on or after July 1, 2025.
