    Sec. 50-12. Collection and remittance of Illinois Use Tax.
    (a) No person shall enter into a contract with a State agency or enter into a subcontract under this Code unless the person and all affiliates of the person collect and remit Illinois Use Tax on all sales of tangible personal property into the State of Illinois in accordance with the provisions of the Illinois Use Tax Act regardless of whether the person or affiliate is a "retailer maintaining a place of business within this State" as defined in Section 2 of the Use Tax Act. For purposes of this Section, the term "affiliate" means any entity that (1) directly, indirectly, or constructively controls another entity, (2) is directly, indirectly, or constructively controlled by another entity, or (3) is subject to the control of a common entity. For purposes of this subsection (a), an entity controls another entity if it owns, directly or individually, more than 10% of the voting securities of that entity. As used in this subsection (a), the term "voting security" means a security that (1) confers upon the holder the right to vote for the election of members of the board of directors or similar governing body of the business or (2) is convertible into, or entitles the holder to receive upon its exercise, a security that confers such a right to vote. A general partnership interest is a voting security.
    (b) Every bid and offer submitted to the State, every submission to a vendor portal, every contract executed by the State and every subcontract subject to Section 20-120 of this Code shall contain a certification by the bidder, offeror, potential contractor, contractor, or subcontractor, respectively, that the bidder, offeror, respondent, potential contractor, contractor, or subcontractor is not barred from bidding for or entering into a contract under subsection (a) of this Section and acknowledges that the chief procurement officer may declare the related contract void if any of the certifications completed pursuant to this subsection (b) are false. If the false certification is made by a subcontractor, then the contractor's submitted bid or offer and the executed contract may not be declared void, unless the contractor refuses to terminate the subcontract upon the State's request after a finding that the subcontract's certification was false.
