Sales Made In General Business Operations

For purposes of G.S. 105-130.4, `sales' by a taxpayer whose business activity consists of manufacturing and selling or purchasing and reselling goods or products includes all gross receipts from the sales of such goods or products (or other property of a kind which would properly be included in the inventory of the taxpayer if on hand at the close of the taxable year) held by the taxpayer primarily for sale to customers in the ordinary course of its trade or business. Gross receipts for this purpose means gross sales, less returns and allowances, and includes all interest income, service charges, carrying charges or time-price differential charges incidental to such sales. Federal and state excise taxes (including sales taxes) shall be included as part of such receipts if such taxes are passed on to the buyer or included as part of the selling price of the product.
