Internal Revenue Code Section 1031 allows investors to exchange either like-kind real or personal property for other like-kind real or personal property. Although the rules for like-kind real estate are fairly broad, the rules to exchange personal property for like-kind or like-class specify that an Exchangor can only receive tax deferral if the sale of personal property is exchanged for the purchase of personal property that falls within the same Product Class or General Asset Class. Product and General Asset Classes, as described in the North American Industry Classification System (NAICS), were developed for use in the classification of establishments and products by the type of activity for which they are engaged. Depreciable tangible personal property is exchanged for property of like-kind if it is exchanged for property of like-class.
