Modification activities encompass “ground up” construction, grading and leveling ground, and wreckage or demolition, or other new contracting activity where none previously existed to the extent such activity cannot otherwise be characterized as maintenance, repair, replacement or alteration (MRRA) (see TPN 18-1, A3); for example, building a new home. Note: Alteration activity exceeding certain thresholds (see above) is categorized as modification activity.
Modification contracting activities include, but are not limited to, the following:
New contractors, out-of-state contractors without a principal business location in Arizona, and contractors who have displayed a history of TPT noncompliance are generally required to provide a bond to the Department to ensure payment of taxes. A principal place of business is defined by statute to mean that in the preceding 12 month period a contractor has maintained a facility in Arizona with at least one full-time employee.

Deduction code 538, Solar Energy Devices, expired December 31, 2016 and is no longer available for a taxpayer filing under the following business codes:
However, a contractor may purchase a qualifying solar energy device from a registered solar energy retailer exempt from tax.
The installation of a solar energy device may be exempt under Arizona Revised Statues (A.R.S.) § 42-5075 (O). This statute states that maintenance, repair, replacement or alteration (MRRA) projects are excluded from the Prime Contracting classification provided these activities meet the definitions and criteria outlined in the statutes. See TPN 15-1 for more information on the distinction between MRRA and taxable modification activities.
Qualifying MRRA Project
If installed on a qualifying MRRA project, the installation of the solar energy device will not be subject to tax. Deduction code 500 would be used to deduct the gross receipts of any MRRA contract on Schedule A of Arizona Form TPT-2 from its gross income reported under the prime contracting classification.
Taxable Modification Project
If installed on a taxable modification project, the gross income from the contract will be included in the tax base subject to tax under the prime contracting classification.
