The law specifically provides but one method for apportioning net income derived from the manufacture or sale of tangible personal property. The part of such income attributable to business within the state shall be that proportion which the gross sales made within the state bear to the total gross sales.
In determining the total net taxable income, the apportionable income attributable to this state, as determined by use of the apportionment fraction, shall be added to the nonapportionable income allocable to this state.
When a taxpayer is engaged in manufacturing and selling or purchasing and reselling goods or products "gross sales" 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 tax period) 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. Federal and state excise 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.
EXAMPLE: The taxpayer, with inventory in State A, sold $100,000 of its products to a purchaser having branch stores in several states including this state. The order for the purchase was placed by the purchaser's central purchasing department located in State B. Twenty-five thousand dollars of the purchase order was shipped directly to purchaser's branch store in this state. The branch store in this state is the "purchaser within this state" with respect to $25,000 of the taxpayer's sales.
EXAMPLE: The taxpayer makes a sale to a purchaser who maintains a central warehouse in this state at which all merchandise purchases are received. The purchaser reships the goods to its branch stores in other states for sale. All of the taxpayer's products shipped to a purchaser's warehouse in this state are property "delivered or shipped to a purchaser within this state".
EXAMPLE: A taxpayer in this state sold merchandise to a purchaser in State A. The taxpayer directed the manufacturer or supplier of the merchandise in State B to ship the merchandise to the purchaser's customer in this state pursuant to purchaser's instructions. The sale by the taxpayer is in this state.
EXAMPLE: The taxpayer, a produce grower in State A, begins shipment of perishable produce to the purchaser's place of business in State B. While en route the produce is diverted to the purchaser's place of business in this state. The sale by the taxpayer is attributed to this state.
This rule is intended to implement Iowa Code section 422.33.
