Iowa Administrative Code Title 701 — Department of Revenue
Iowa Admin. Code r. 701—282.5(423) — Property used to manufacture certain vehicles to be leased
Tangible personal property that becomes an integral part of a vehicle as described in Iowa Code section 423.6(8) is exempt Revenue from use tax, subject to the limitations provided in Iowa Code section 423.6(8). However, this rule does not exempt the sale of the tangible personal property used from the imposition of sales tax under Iowa Code section 423.2 if that property is otherwise subject to sales tax.
