Personal Property Valuation Guidelines

Section I – Introduction

Utah Code in Title 59 requires the taxation of property for the funding of local government and Utah schools. Property tax is assessed on both real property and personal property. Generally, personal property used in business is subject to property taxes. Utah law requires business personal property to be reported to the county assessor where the property is located (has situs) on a tax form identified as a Personal Property Signed Statement. Registered motor vehicles and recreational vehicles are subject to Uniform Fees. Personal Property is taxed based on its taxable value as of January 1 of each year. In order to value personal property, the Utah State Tax Commission provides personal property classification schedules which are used by all county assessors in Utah.

Determining Business Personal Property Class

Personal Property is valued using a classification system referred to as “Recommended Personal Property Valuation Schedules”. These schedules identify various types of personal property and provide a “percent good” of acquisition cost for commercial personal property. To determine property type or “class” refer to the Classification Guide. To determine personal property value refer to the Recommended Personal Property Valuation Schedules for each class of property. These valuation schedules provide a factor to be applied to acquisition cost (refer to the Definition of Acquisition Cost below) and acquisition year to determine taxable value. Once taxable value is determined, the local taxing area rate is applied to calculate the tax.

Applying Valuation Schedule to Determine Taxable Value

Taxable value for business personal property classes subject to an ad valorem tax is calculated by applying the acquisition cost at the retail level of trade by the percent good factor of the year acquired.

Definition of Acquisition Cost

Cost of Acquisition must include all costs required to put an item into service. In addition to the cost of the item, include the following costs:

  1. Freight in, includes shipping costs, loading at origin, unloading at destination, crating, skidding, and other applicable costs of shipping.
  2. Installation, engineering, rigging, erection or assembly to include foundations, pilings, utility connections and any other costs related to installation.
  3. Excise and sales taxes.
  4. Any other costs related to putting personal property into service are to be included in acquisition cost.

Indirect costs such as debugging, licensing fees, permits, insurance or security are not included in acquisition cost.

Definition of an Item of Taxable Tangible Personal Property

An item of taxable tangible personal property means equipment, machinery, furniture or other tangible personal property that is functioning at its highest and best use for the purpose it was designed and constructed and is generally 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 item of machinery or equipment as a whole. 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.

Section IV – Guides and Schedules Development and Methodology

Tax Commission Administrative Rule 884-24P-33 details requirements regarding personal property valuation guides and schedules pursuant to Utah Code, Section 59-2-301. This rule requires that valuation schedules are to be reviewed and updated annually by the Property Tax Division, and must be approved by the Utah State Tax Commission. Analysis of new market data form the basis for revision and updating valuation schedules. The schedules are developed using the following methodology:

  • Schedules for Personal Property Classes 1, 2, 3, 5, 8, 10, 12, 15, 16, 20, 25, and 27 are subject to an ad valorem tax and refer to the Internal Revenue Service (IRS) Class Life to establish average economic life trended to replacement cost new using the Marshall Valuation Service Personal Property Cost Index. Class 13 (Heavy Equipment) is developed from samples of heavy equipment sales. When local property values are not reflected by personal property schedules, assessors may establish market values using other acceptable appraisal methods. According to Tax Commission Administrative Rule 884-24P-33, if such deviation affect an entire class of personal property, the county assessor must submit a written report documenting the schedule changes to the Tax Commission for approval prior to use. 
  • Schedules for registered motor vehicles and recreational vehicles, subject to state wide uniform fees are developed from samples of vehicle sales as reported in published valuation guides and include: Class 6 Heavy & Medium Duty Trucks, Class 17, Vessels 31 feet in length & longer, Class 21 Commercial Trailers. These classes are subject to “value based” uniform fees.
  • The Following Classes are subject to “Age Based” fees set in statute by the legislature: Class 9 Off-Highway ATVs, Class 11 Street Motorcycles, Class 14 Motor Homes, Classes 17a through 17e, Vessels below 31 feet in length, Class 18, Travel Trailers, Class 18a, Tent trailers and Truck Campers, Class 21a, Non-commercial Trailers, Class 22, Passenger vehicles, Class 22a Small Motor Vehicles and Class 26, Personal Water Craft
