This list of principal business activities and their associated codes is designed to classify an enterprise by type of activity in which it is engaged. These six-digit codes are derived from the North American Industry Classification System (NAICS) and do not resemble prior year codes. Select the category that best describes your primary business activity (for example Real Estate). Then select the activity that best identifies the principal source of your sales or receipts (for example, real estate agent). Now find the six-digit code assigned to this activity and enter it on all appropriate forms. The business tax application (BT-1) will accommodate up to four different codes related to your business. The codes will assist the Department in mailing tax bulletins and other information applicable to your business.
