Example: A person engaged in business in the State of selling appliances at retail is a retailer. Any charges by such person on or after March 1, 2016 for a service call for troubleshooting only is a charge for repair, maintenance, and installation services and is subject to tax. North Carolina Department of Revenue Sales and Use Tax Division Page 3 of 8 SD-16-2 A person whose only business activity is providing repair, maintenance, and installation services, where the person’s activities do not otherwise meet the definition of “retail trade,” is not a retailer and is not liable for sales or use tax on the sales price of or gross receipts derived from repair, maintenance, and installations services on or after March 1, 2016. Example: A person who only receives gross receipts from sharpening knives owned by customers and does not make other retail sales is not a retailer for sales and use tax purposes and is not liable for tax on receipts from sharpening knives on or after March 1, 2016, no matter that such charge meets the definition of “repair, maintenance, and installation services.”
