Child Support Information

In Illinois, parents have a duty to financially support their minor children. Typically, the amount for child support will be a fixed dollar amount based on a certain percentage of the supporting parent's net income. The percentage will depend on the number of children the supporting parent will be supporting. A child support order in Illinois is in the form of a Uniform Order for Support.

Child support payments cover the basic needs of the child such as food, clothing and shelter.  Child support payments do not necessarily include expenses related to education, medical/dental costs, extracurricular activities or daycare.  A court may order that the supporting parent pay additional amounts for these or other child related expenses.

In determining a dollar amount for child support, Illinois courts are required to follow the minimum guidelines set forth by statute.  In rare circumstances, the court can deviate from the child support guidelines.  The current guidelines for child support are as follows:


Percent of Payor’s Net Income











6 or more


Generally, the net income of the supporting parent equals the gross income of the supporting parent minus the following:

  • federal income tax
  • state income tax
  • Social Security (FICA payments)
  • mandatory retirement contributions required by law or as a condition of employment (voluntary retirement plans are not deducted)
  • union dues
  • dependent and individual health insurance premiums
  • life insurance premiums ordered by the court to secure support payments (effective January 1, 2012)
  • prior obligations of support or maintenance actually paid pursuant to court order foster care payments paid by the Department of Children and Family Services
  • expenditures for repayment of certain debts including but not limited to student loans and necessary medical expenses

After the Court has determined a child support amount, the Court will enter a Uniform Order for Support.  The Uniform Order of Support will state the following:

  • amount of child support payment
  • frequency of payments (i.e., weekly, bi-weekly, bi-monthly, monthly)
  • who is responsible for providing health insurance for the child or children
  • percentage of uninsured medical costs for which payor is responsible
  • whether payments are to be deducted from payor’s paycheck or payor is responsible for making the payments directly
  • whether the payments are to be paid directly to the payee or to the Illinois State Disbursement Unit
  • termination date for support payments
  • amount of penalty for late support payments

The Illinois State Disbursement Unit (ILSDU) is the payments processing center for all Illinois child support payments. The ILSDU processes child payments from the payors and issues checks or direct deposits to the payees.

Establishing Parentage Q & A

Failure to pay child support as ordered does not entitle the parent receiving support to withhold parenting time from the supporting parent.  The status of child support payments does not affect the parenting time rights of the parent required to pay support.

Likewise, a parent required to pay support cannot withhold child support payments because the parent receiving support is denying parenting time.  No matter how often a parent sees a child, that parent has an affirmative obligation to financially support the child.
