IDAPA 35.01.02.013 — ROAD AND PAVING CONTRACTORS (RULE 013)

Sections 63-3609, 63-3615, Idaho Code
01.
In General. This rule illustrates the application of Idaho sales and use tax to specific activities of
road and paving contractors. The general principles stated in Rule 012 of these rules apply equally to road and paving
contractors.
(3-31-22)
02.
Road or Paving Contractor. A road or paving contractor is a contractor improving real property.
The use of materials over which he exercises right or power in the course of performing the contract is taxable. This
is true even if an exempt entity, such as a government agency, owns the material. It is also true if the contractor does
the work under the full or partial supervision of the person for whom the contractor is performing the contract.
(3-31-22)
03.
Examples. Here are some examples of taxable materials contractors use in paving and road
contracts:
(3-31-22)
a.
Example 1: A contractor is hired to pave a road for a city. The materials the contractor will use are
taxable, regardless of ownership, and include rock, sand, asphalt oil, chemicals, bonding agents, or any other like
materials which become the aggregate pavement.
(3-31-22)
b.
Example 2: A contractor is hired to chip seal a local road. The chip seal includes a layer of liquid
asphalt or similar material applied to the road with an immediate layer of rock chips applied on top of the wet asphalt.
A roller sets the rock chips in place. Once this dries, the surface is cleaned and another oil seal or like product is
applied. These three items and any other materials used to form the aggregate chip seal are taxable.
(3-31-22)
c.
Example 3: A contractor is hired to perform landscaping for the barrow pits and shoulders of a new
highway. The highway district provides the grass seed and some bushes for the project. The contractor provides labor
to sow the seed, plant the bushes, and labor and materials to provide erosion control, land leveling, contouring, etc.
The contractor owes sales or use tax on all materials consumed, including those provided by the highway district.
(3-31-22)
d.
Example 4: A contractor is hired to install a new bridge and provide drainage for a new freeway
interchange. The highway district provides the bridge components and culverts needed for the project, and the
contractor provided all of the remaining materials and the labor for the project. The contractor will owe sales or use

tax on all materials he consumes including the bridge components and culverts provided by the highway district, as
well as on the materials the contractor purchased for use on the project.
(3-31-22)
e.
Example 5: A contractor is hired to install traffic control lights, signage, and roadway illumination
for a rebuilt section of roadway. The highway district provides the traffic control signals and the permanent signage
for the highway so that all signage will be consistent throughout the highway district. The contractor owes use tax on
the value of the traffic signals and signage provided by the highway district as well as on the cost of electrical wiring,
signal wiring, and the lights and light poles, etc., purchased and consumed by the contractor.
(3-31-22)
04.
Materials. The sale or use of materials which are extracted and crushed is taxable. Use tax does not
apply to the use of natural materials that are secured on site and used without significant change.
(3-31-22)
05.
Rock Crushing. The application of the sales or use tax to rock crushing operations depends upon
the circumstances of the case.
(3-31-22)
a.
A sale of crushing only is a sale of a taxable processing service. In this circumstance the crusher
obtains raw material owned by another, crushes the rock, and stockpiles it for subsequent use either by the owner or a
third party. Unless an exemption applies, the crusher charges tax on all such sales.
(3-31-22)
b.
A contractor who applies crushed rock to the highway pursuant to a contract is a person engaged in
improving real property. If the contractor applying the crushed rock purchases the rock, the purchase price will be
taxable. If the contractor applies rock owned by another party, the contractor will be responsible for a use tax on the
value of the rock, unless the other party paid a sales tax upon its acquisition. This is true even if a government agency
supplied the rock. If a recent retail acquisition of the crushed rock exists, the retail price is to be presumed to be the
value of the material. If a recent retail sales price does not exist, then value is to be determined by the current
acquisition cost of like material from the same or a similar source. For purposes of this section, a retail acquisition
within one (1) year of the time of the performance of the contract is to be presumed to be a recent sales price.
(3-31-22)
c.
A contractor whose contract calls for him to both crush and apply rock to a road is also subject to
sales or use tax on the value of the rock whether the contract is performed for a governmental or private contractee.
The value is to be determined by the royalty or similar charge for raw materials. If a royalty or similar charge does not
exist, then the value will be determined as the royalty fee or value of like material from a similar source. If the
contractor chooses to have the rock crushed by a subcontractor, the measure of the use tax is on the crushed value.
(3-31-22)
d.
A sale of rock crushing services to a retailer who will sell the rock is an exempt sale. The sale of
crushed rock to a consumer is a taxable sale unless an exemption applies.
(3-31-22)
06.
Production Exemption.
(3-31-22)
a.
Since a contractor improving real property is defined as the consumer of materials incorporated
into realty, he is not producing an article for resale. Therefore, the production exemption does not apply to the use of
equipment used by contractors to produce asphalt or concrete which are used to complete paving contracts. (3-31-22)
b.
A business which is primarily devoted to producing crushed rock, asphalt, or concrete which is
ultimately sold at retail will qualify for the production exemption. See Idaho Administrative Sales Tax Rules 079 and
