Sec. 151.056.  PROPERTY CONSUMED IN CONTRACTS TO IMPROVE REAL PROPERTY.  (a)  A contractor is the consumer of tangible personal property furnished by him and incorporated into the property of his customer if the contract between the contractor and his customer contains a lump-sum price covering both the performance of the service and the furnishing of the necessary incidental material.
(b)  A contractor is the seller of tangible personal property furnished by him and incorporated into the property of his customer, from whom he shall collect the tax, if the contract between the contractor and his customer contains separate amounts for the performance of the service and for the furnishing of the necessary incidental material.  The tax rate is applied to the price of the materials as agreed in the contract or the price of the materials to the contractor, whichever is the greater.
(c)  If a contractor has paid the sales tax to his supplier when the tangible personal property is purchased, the contractor may credit the amount of the tax paid to the supplier against the tax imposed as provided in Subsection (b) of this section with respect to a subsequent sale of the property.
(d)  In this section, "contractor" means a person who makes an improvement on real estate and who, as a necessary or incidental part of the service, incorporates tangible personal property into the property improved.
(e)  This section does not apply to the use or consumption of tangible personal property as a necessary or incidental part of a taxable service.
(f)  A contractor is not eligible for the exemption provided by Section 151.318 on items used in the performance of a contract to improve real property.
(g)  In this subsection, "ready mix concrete contractor" means a person who manufactures or produces ready mixed concrete for construction purposes and incorporates the ready mixed concrete in the property improved.  A ready mix concrete contractor performing a contract must separate and individually invoice the customer for each yard of ready mixed concrete produced and consumed for the improvement of real property and collect and remit the tax imposed under this chapter on the ready mixed concrete produced and consumed.  The tax rate is applied to the price of the materials determined by the greater of the invoice price or fair market value of ready mixed concrete incorporated into the project.  This subsection does not apply to an invoice submitted by a ready mix concrete contractor for a public works project.
