      (2)   “Governmental Entity” means the Federal Government, the State of Arizona, any other state, or any political subdivision, department, or agency of any of the foregoing; provided further that persons contracting with such a governmental entity to operate any part of a governmentally adopted and controlled program to provide urban mass transportation shall be deemed a governmental entity in all activities such person performs when engaged in said contract.
      (3)   “Non-Licensed Business” means any person conducting any business activity for gain or profit, whether or not actually realized, which person is not required to be licensed for the conduct or transaction of activities subject to the tax imposed under this Chapter.
      (4)   “Proprietary Club” means any club which has qualified or would otherwise qualify as an exempt club under the provisions of 26 U.S.C.

      (5)   “Public Educational Entity” means any educational entity operated pursuant to any provisions of Title 15, Arizona Revised Statutes.
   (b)   Transactions which, if conducted by any other person, would produce gross income subject to tax under this Chapter shall not be subject to the imposition of such tax if conducted entirely by a public educational entity; governmental entity, except “proprietary activities” of municipalities as provided by Regulation; or non-licensed business.
   (c)   Transactions which, if conducted by any other person, would produce gross income subject to the tax under this Chapter shall not be subject to the imposition of such tax if conducted entirely by a federally exempt organization or proprietary club with the following exceptions:
      (1)   Transactions involving proprietary clubs and organizations exempt under 26 U.S.C. Section 501(c)(7), (8), and (9), where the gross revenue of the activity received from persons other than members and bona fide guests of members is in an amount in excess of fifteen percent (15%) of total gross revenue, as prescribed by Regulation. In the event this fifteen percent (15%) limit is exceeded, the entire gross income of such entity shall be subject to the applicable tax.

   (d)   Except as may be provided elsewhere in this Chapter, transactions where customers are exempt organizations, proprietary clubs, public educational entities, governmental entities, or non-licensed businesses shall be deemed taxable transactions for the purpose of the imposition of taxes under this Chapter, notwithstanding that property so acquired may in fact be resold or leased by the acquiring person to others. In the case of sales, rentals, leases, or licenses to proprietary clubs or exempt organizations, the vendor may be relieved from the responsibility for reporting and paying tax on such income only by obtaining from its vendee a verified statement that includes:
      (1)   a statement that when the property so acquired is resold, rented, leased, or licensed, that the otherwise exempt vendee chooses, or is required, to pay Town Privilege Tax or an equivalent excise tax on its gross income from such transactions and does in fact file returns on same; and
      (2)   the Privilege License number of the otherwise exempt vendee; and
      (3)   such other information as the Tax Collector may require.
   (e)   Franchisees or concessionaires operating businesses for or on behalf of any exempt organization, governmental entity, public educational entity, proprietary club, or non-licensed business shall not be considered to be such an exempt organization, club, entity, or non-licensed business, but shall be deemed to be a taxpayer subject to the provisions of this Chapter, except as provided in the definition of governmental entity, regarding urban mass transit.
   (f)   In any case, if a federally exempt organization, proprietary club, or non-licensed business rents, leases, licenses, or purchases any tangible personal property for its own storage or use, and no Town Privilege or Use Tax or equivalent excise tax has been paid on such transaction, said organization, club, or business shall be liable for the Use Tax upon such acquisitions or use of such property.
