Wyoming Statutes Title 39. Taxation and Revenue § 39-16-303. Imposition

(i) Any contractor who furnishes tangible personal property under contract or in the development of real property is the consumer or user of the tangible personal property within the meaning of the use tax laws of Wyoming;

(ii) Any subcontractor who contracts with a general or prime contractor is liable for sales taxes as a general or prime contractor. The general or prime contractor shall withhold three percent (3%), plus the increased rate under W.S. 39-15-104(b) if the tax under that section is in effect, of the payments due a nonresident subcontractor arising out of the contract entered into between both contractors. The contractor shall withhold the payments until the subcontractor furnishes him with a certificate issued by the department showing all sales taxes accruing by reason of the contract between them have been paid. The department may demand the withholdings at any time to satisfy the sales tax liability of the subcontractor and any balance shall be released by the department to him. If a contractor fails to withhold payments or refuses to remit them upon demand by the department he is liable for any sales taxes due the state by the nonresident subcontractor. This paragraph shall not apply to any subcontractor hired to provide labor only to alter, construct, improve or repair real property;

(iii) To secure payment of use taxes by nonresident prime contractors, each nonresident contractor shall file with the department of revenue a surety bond or legal security equal to three percent (3%), plus the increased rate under W.S. 39-16-104(b) if the tax under that section is in effect, of the payments due under the contract or an amount determined by the department. The bond shall be conditioned upon the payment of all use taxes which become due and payable to this state under the contract or in the real property development. This bond requirement does not apply for a nonresident contractor who has furnished a surety bond as provided by W.S. 39-16-306(b)(v);

(iv) Any nonresident prime contractor and any resident prime contractor who hires a nonresident subcontractor shall register any project with the department of revenue not more than fifteen (15) days following the start of a project pursuant to a contract. The nonresident prime contractor shall provide a properly executed bond as required by paragraph (iii) of this subsection, or a cash deposit of not less than four percent (4%) of the total payments due under the contract. The cash deposit shall be refunded to the contractor upon the department's receipt of a properly executed surety bond or upon satisfactory completion of the project. Failure to register with the department within the time period required by this paragraph shall result in a penalty assessment of one percent (1%) of the total payments due under the contract.
