This list of Principal Business Activities and their associated codes is designed to classify an enterprise by the type of activity in which it is engaged to facilitate the administration of the Internal Revenue Code. These Principal Business Activity Codes are based on the North American Industry Classification System.
Using the list of activities and codes below, determine from which activity the business derives the largest percentage of its “total receipts.” Total receipts is defined as the sum of gross receipts or sales (page 1, line 1a); all other income (page 1, lines 4 through 7); income reported on Schedule K, lines 3a, 5, 6a, and 7; income or net gain reported on Schedule K, lines 8, 9a, 10, and 11; and income or net gain reported on Form 8825, lines 2, 19, and 20a. If the business purchases raw materials and supplies them to a subcontractor to produce the finished product, but retains title to the product, the business is considered a manufacturer and must use one of the manufacturing codes (311110-339900).
Once the Principal Business Activity is determined, enter the six-digit code from the list below on page 1, item C. Also enter a brief description of the business activity in item A and the principal product or service of the business in item B.
