423.17  Sourcing rules for various types of leased or rented equipment which is not transportation equipment.
  The lease or rental of motor vehicles, trailers, semitrailers, or aircraft that do not qualify as transportation equipment, as defined in section 423.15, subsection 3, shall be sourced as follows:
  1.  For a lease or rental that requires recurring periodic payments, each periodic payment is sourced to the primary property location. The primary property location shall be as indicated by an address for the property provided by the lessee that is available to the lessor from its records maintained in the ordinary course of business, when use of this address does not constitute bad faith. This location shall not be altered by intermittent use at different locations.
  2.  For a lease or rental that does not require recurring periodic payments, the payment is sourced the same as a retail sale in accordance with the provisions of section 423.15, subsection 1.
  3.  This section does not affect the imposition or computation of sales or use tax on leases or rentals based on a lump sum or accelerated basis, or on the acquisition of property for lease.
