(1) As used in ORS 314.650, the sales factor is a fraction, the numerator of which is the total sales of the taxpayer in this state during the tax period, and the denominator of which is the total sales of the taxpayer everywhere during the tax period. (2) Sales of tangible personal property are in this state if: (a) The property is delivered or shipped to a purchaser, other than the United States Government, within this state regardless of the f.o.b. point or other conditions of the sale; or (b) The property is shipped from an office, store, warehouse, factory, or other place of storage in this state and the purchaser is the United States Government or the taxpayer is not taxable in the state of the purchaser. For purposes of this paragraph: (A) The sale of goods shipped from a public warehouse is not considered to take place in this state if: (i) The taxpayer’s only activity in Oregon is the storage of the goods in the public warehouse prior to shipment; or (ii) The taxpayer’s only activities in Oregon are the storage of the goods in the public warehouse prior to shipment and the presence of employees within this state solely for purposes of soliciting sales of the taxpayer’s products; and (B) "Taxpayer" means a taxpayer as defined in section 7701 of the Internal Revenue Code, an affiliate of the person storing goods in a public warehouse or a person that is related under section 267 of the Internal Revenue Code to the person storing goods in a public warehouse. (3) Subsection (2)(b) of this section does not apply to sales of tangible personal property if: (a) The sales are included in the numerator of a formula used to apportion income to another state of the United States, a foreign country or the District of Columbia; and (b) The other state, a foreign country or the District of Columbia has imposed a tax on or measured by the apportioned income. (4) Sales, other than sales of tangible personal property, are in this state if the taxpayer’s market for sales is in this state, as determined under ORS 314.666. (5) Where the sales apportionment factor is determined by administrative rule pursuant to ORS 317.660 or other law, the Department of Revenue shall adopt rules that are consistent with the determination of the sales factor under this section. (6) The department may determine that a warehouse that meets the definition of "public warehouse" under this section may not be treated as a public warehouse if the warehouse is being used primarily for tax avoidance purposes or if transactions related to the use of the warehouse are primarily for tax avoidance purposes. (7) As used in this section, "public warehouse": (a) Means a warehouse owned or operated by a person that does not own the goods stored in the warehouse; and (b) Does not include a warehouse that is owned by a person that is related to the person that owns goods that are stored in the warehouse, as determined under section 267 of the Internal Revenue Code, or an affiliate of the person that owns goods that are stored in the warehouse.
