Auto Dealerships

The IRS published a comprehensive audit techniques guide used by examiners who evaluate cost segregation studies submitted by taxpayers. This guide helps taxpayers and study providers understand how to prepare audit-defensible studies.

Last updated by the IRS: February 2025.

F. Auto Dealership Industry

(1) LMSB 4-0208-006 Field Directive on the Planning and Examination of Cost Segregation Issues in the Auto Dealership Industry intended to provide technical guidance to effectively reduce exam time and taxpayer burden. The matrix contained in attachment A is a new chapter in the Cost Segregation Audit Technique Guide. This matrix will provide assistance to agents in the classification and examination of a taxpayer who is recovering costs through depreciation of tangible property used in the Auto Dealership Industry. It is partially reproduced below.

(2) BACKGROUND — The crux of cost segregation is determining whether an asset is § 1245 property (shorter cost recovery period property) or § 1250 property (longer cost recovery period property). The most common example of § 1245 property is depreciable personal property, such as equipment. The most common examples of § 1250 property are buildings and building components, which generally are not § 1245 property.

(3) The difference in recovery periods has placed the Internal Revenue Service and taxpayers in adversarial positions in determining whether an asset is § 1245 or § 1250 property. Frequently, this causes the excessive expenditure of examination resources. The Director for the Heavy Manufacturing and Transportation Industry chartered a working group to address the most efficient way to approach cost segregation issues specific to the Auto Dealership Industry. The group produced the attached matrix and related definitions as a tool to reduce unnecessary disputes and foster consistent audit treatment.

(4) ISSUE TRACKING — UIL Code 168-20-00 Classification of Property.

(5) PLANNING AND EXAMINATION RISK ANALYSIS — The Auto Dealership Industry Matrix recommending the categorization and general depreciation system recovery period of various assets is attached as Exhibit A. (For recovery periods under the § 168(g) alternative depreciation system, see Revenue Procedure 87-56, 1987-2 CB 674). If the taxpayer’s tax return position for these assets is consistent with the recommendations in Auto Dealership Matrix (Exhibit A), examiners should not make adjustments to categorization and recovery periods. If the taxpayer reports assets differently, then adjustments should be considered.

(6) Refer especially to Chapter 6.C, which provides examples and general rules for asset classification.

(7) INTERNAL COMMUNICATIONS — Questions regarding the development of the Cost Segregation issue for Auto Dealerships should be addressed to the Deductible and Capital Expenditures (DCE) Practice Network. This LMSB Directive is not an official pronouncement of the law or the position of the Service and cannot be used, cited, or relied upon as such.

(8) LMSB DIRECTIVE ON COST SEGREGATION IN THE AUTO DEALERSHIP INDUSTRY — EXHIBIT A — This matrix, which is part of the Cost Segregation Audit Techniques Guide, is intended to provide direction to effectively utilize resources in the classification and examination of property used in the operation of an Auto Dealership. General fact patterns specific to this industry have been considered in the classification of these assets and may not be applicable to other industries. Similarly, asset classification guidance issued for other industries is based on the general fact pattern for that industry and may not be applicable to an Auto Dealership situation. For examination techniques and historical background related to this issue, refer to the Cost Segregation Audit Techniques Guide.

(9) NOTE: In the case of certain leasehold improvement property, the classifications in this directive are superseded to the extent that the American Jobs Creation Act of 2004 modifies § 168. Thus, a 15-year straight line recovery period should replace the recovery period shown in the following matrix if the asset is “qualified leasehold improvement property” (as defined in § 168(e)(6)) placed in service by the taxpayer after 10/22/04 and before 1/1/08.
