If you make or buy goods to sell, you can deduct the cost of goods sold from your gross receipts on Schedule C. However, to determine these costs, you must value your inventory at the beginning and end of each tax year.
This chapter applies to you if you are a manufacturer, wholesaler, or retailer or if you are engaged in any business that makes, buys, or sells goods to produce income. This chapter does not apply to a personal service business, such as the business of a doctor, lawyer, carpenter, or painter. However, if you work in a personal service business and also sell or charge for the materials and supplies normally used in your business, this chapter applies to you.
