(35 ILCS 520/23) (from Ch. 120, par. 2173)
    Sec. 23. Demand and Seizure. In addition to any other remedy provided for by the laws of this State, if the tax imposed by this Act is not paid within the time required by this Act, the Department, or some person designated by it, may cause a demand to be made on the taxpayer for the payment thereof. If the demand is made before the issuance of an assessment, the demand shall inform the taxpayer that, within 5 days after the demand, he or she must either pay the tax or show the Department that the findings in the demand are erroneous. If the taxpayer does not either pay the tax or show the Department that the findings in the demand are erroneous within 5 days after the demand, the Department shall issue a jeopardy assessment under the procedures outlined in Section 16, and may issue a warrant directed to any sheriff or other person authorized to serve process, commanding the sheriff or other person to levy upon the personal property and rights to personal property (whether tangible or intangible) of the taxpayer, without exemption, found within his jurisdiction, for the payment of the amount thereof with the added penalties, interest and the cost of executing the warrant. The term "levy" includes the power of distraint and seizure by any means. In any case in which the warrant to levy has been issued, the sheriff or other person to whom the warrant was directed may seize and sell such property or rights to property. No real or personal property may be sold, however, until the time for protesting a jeopardy assessment has passed or the jeopardy assessment has otherwise become final. Such warrant shall be returned to the Department together with the money collected by virtue thereof within the time therein specified, which shall not be less than 20 nor more than 90 days from the date of the warrant. The sheriff or other person to whom such warrant is directed shall proceed in the same manner as prescribed by law in respect to the enforcement against property upon judgments by a court, and shall be entitled to the same fees for his services in executing the warrant, to be collected in the same manner.
    Any officer or employee of the Department designated in writing by the Director is authorized to serve process under this Section to levy upon accounts or other intangible assets of a taxpayer held by a financial organization, as defined in Section 1501 of the Illinois Income Tax Act. In addition to any other provisions of this Section, any officer or employee of the Department designated in writing by the Director may levy upon the following property and rights to property belonging to a taxpayer: contractual payments, accounts and notes receivable and other evidences of debt, and interest on bonds, by serving a notice of levy on the person making such payment. Levy shall not be made until the Department has caused a demand to be made on the taxpayer in the manner provided above. A lien obtained hereunder shall have priority over any subsequent lien obtained pursuant to Section 12-808 of the Code of Civil Procedure, except that liens for the support of a spouse or dependent children shall have priority over all liens obtained hereunder.
    In any case where property or rights to property have been seized by an officer of the Illinois Department of State Police, or successor agency thereto, under the authority of a warrant to levy issued by the Department of Revenue, the Department of Revenue may take possession of and may sell such property or rights to property and the Department of Revenue may contract with third persons to conduct sales of such property or rights to the property. No real or personal property may be sold, however, until the time for protesting a jeopardy assessment has passed or the jeopardy assessment has otherwise become final. In the conduct of such sales, the Department of Revenue shall proceed in the same manner as is prescribed by law for proceeding against property to enforce judgments which are entered by a circuit court of this State. If, in the Department of Revenue's opinion, no offer to purchase at such sale is acceptable and the State's interest would be better served by retaining the property for sale at a later date, then the Department may decline to accept any bid and may retain the property for sale at a later date.
