Example 1: Corporation B sells all the assets of one of its divisions for a gain, which is properly reported as business income. The assets sold consisted of real property, tangible personal property, and goodwill. The portion of the gain attributable to the sale of tangible personal property shall be apportioned to New York State using the rules for net gains from the sale of tangible personal property in section 4-2.1 of this Part, the portion attributable to the sale of real property shall be apportioned to New York State using the rules for net gains from the sale of real property in section 4-2.2 of this Part, and the portion attributable to the sale of goodwill shall be apportioned to New York State using the rules for other services and other business receipts in Subpart 4-4 of this Part.
Example 2: Book Corp sells electronic books and physical books through its website. Customers purchase a bundle of both an electronic and physical book, the price of which includes a discounted price of the electronic and physical book, but the breakdown is not separately stated. For bundled purchases, the electronic book is available for immediate download by the customer and the physical book is shipped from Book Corp to the customer. Customer B, with a New York billing address, purchases a bundled purchase of an electronic and a physical book commingled into one receipt. As the receipt cannot be reasonably divided between the electronic book and the physical book, the entire receipt should be sourced as a sale of tangible personal property.
