(1) As used in this rule:
- (a) "Acquisition cost" means the same as that term is defined in Section 59-2-102.
(b)(i) "Actual cost" includes the value of components necessary to complete the vehicle, such as tanks, mixers, special containers, passenger compartments, special axles, installation, engineering, erection, or assembly costs.
- (ii) Actual cost does not include sales or excise taxes, maintenance contracts, registration and license fees, dealer charges, tire tax, freight, or shipping costs.
(c) "Assessing authority" means:
- (i) the State Tax Commission for property assessed under Title 59, Chapter 2, Part 2, Assessment of Property; and
- (ii) the county assessor for property assessed under Title 59, Chapter 2, Part 3, County Assessment.
(d) "Cost new" means the actual cost of the property when purchased new.
(i) Except as otherwise provided in this rule, the assessing authority shall rely on the following sources to determine cost new:
- (A) documented actual cost of the new or used vehicle; or
- (B) recognized publications that provide a method for approximating cost new for new or used vehicles.
(ii) For the following property purchased used, the assessing authority may determine cost new by dividing the property's actual cost by the percent good factor for that class:
- (A) Class 6 heavy and medium duty trucks;
- (B) Class 13 heavy equipment;
- (C) Class 17 vessels equal to or greater than 31 feet in length; and
- (D) Class 21 commercial trailers.
- (e) For purposes of Sections 59-2-108 and 59-2-1115, "item of taxable tangible personal property" means a piece of equipment, machinery, furniture, or other piece of tangible personal property that is functioning at its highest and best use for the purpose it was designed and constructed and is capable of performing that function without being combined with other items of personal property. An item of taxable tangible personal property is not an individual component part of a piece of machinery or equipment, but the piece of machinery or equipment. For example, a fully functioning computer is an item of taxable tangible personal property, but the motherboard, hard drive, tower, or sound card are not.
(f) "Percent good" means an estimate of value, expressed as a percentage, based on a property's acquisition cost or cost new, adjusted for depreciation and appreciation.
- (i) The percent good factor shall be applied against the acquisition cost or the cost new to derive taxable value for the property.
- (ii) Percent good schedules shall be derived from an analysis of the Internal Revenue Service Class Life, the Marshall and Swift Cost index, other data sources or research, and vehicle valuation guides such as Price Digests.
(2) Each year percent good schedules for use in computing personal property valuation shall be updated and recommended by the Property Tax Division for adoption by the Commission by rule in accordance with Section 59-2-107.
- (a) County assessors may deviate from the schedules when warranted by specific conditions affecting an item of personal property. When a deviation will affect an entire class or type of personal property, a written report, substantiating the changes with verifiable data, must be presented to the Commission. Alternative schedules may not be used without prior written approval of the Commission.
- (b) A party may request a deviation from the value established by the schedule for a specific item of property if the use of the schedule does not result in the fair market value for the property at the retail level of trade on the lien date, including any relevant installation and assemblage value.
(3) This rule does not apply to:
- (a) a vehicle subject to the age-based uniform fee under Section 59-2-405.1;
