Illinois Statutes Chapter 305. Public Aid § 5/10-17.9. Past due support information to State Department of Revenue

(a) The Illinois Department may provide by rule for certification to the Illinois Department of Revenue of past due support owed by responsible relatives under a support order entered by a court or administrative body of this or any other State on behalf of resident or non-resident persons. The rule shall provide for notice to and an opportunity to be heard by each responsible relative affected. Any final administrative decision rendered by the Department shall be reviewed only under and in accordance with the Administrative Review Law.  1 A responsible relative may avoid certification to the Illinois Department of Revenue by establishing a satisfactory repayment record as determined by the Illinois Department of Healthcare and Family Services.

(b) A certified past due support amount shall be final. The certified amount shall be payable to the Illinois Department of Revenue upon written notification of the certification to the responsible relative by the Illinois Department of Revenue.

(c) In the event a responsible relative overpays pursuant to collection under this Section and the applicable Sections of the Illinois Income Tax Act,  2 the overpayment shall be a credit against future support obligations. If the current support obligation of the responsible relative has terminated under operation of law or court order, any moneys overpaid but still in the possession of the Department shall be promptly returned to the responsible relative.

(d) Except as otherwise provided in this Article, any child support delinquency certified to the Illinois Department of Revenue shall be treated as a child support delinquency for all other purposes, and any collection action by the State's Attorney or the Illinois Department of Revenue with respect to any delinquency certified under this Article shall have the same priority against attachment, execution, assignment, or other collection action as is provided by any other provision of State law.

(e) Any child support delinquency collected by the Illinois Department of Revenue, including those amounts that result in overpayment of a child support delinquency, shall be paid to the State Disbursement Unit established under Section 10-26.
