Neb. Rev. Stat. § 48-2104: Neb. Rev. Stat. § 48-2104

(1) Before performing any construction work in Nebraska, a contractor shall be registered with the department. If a contractor does business under more than one name, the contractor shall obtain a registration number for each name under which the contractor is doing business. Any person who performs work or has work performed on his or her own property or any person who earns less than five thousand dollars annually for construction services is not a contractor for purposes of the Contractor Registration Act.

(2) An exemption from the requirements under subsection (1) of this section does not exempt a contractor from withholding requirements under the Nebraska Revenue Act of 1967.
