Interest Policy

Effective January 1, 2021, all unadjudicated interest will be removed from the balance being enforced by DCSS. Additionally, DCSS no longer automatically charges interest on past-due balances. After certain criteria are met, as detailed below, customers will have the opportunity to request adjudication and enforcement of interest

➢  Interest Legislation
➢  Interest Payments/IRS Form 1099-INT
➢  Interest Rate

Adjudicated Interest Requests

The amended procedures to establish and enforce interest became effective January 1, 2021, signed
into law as Public Act 101-0336 on August 9, 2019.

As of January 1, 2021, DCSS no longer establishes interest for every case.  Interest is only

established and/or enforced for participants meeting the criteria contained in 89 Ill. Adm. Code

160.89.  Interest is only assessed when your youngest child has emancipated, no current or past due

support remains due, and your written request is received by the Department within one year of

qualifying for interest enforcement.  See link below for entire rule.

An opportunity to request interest adjudication, through the Department of Healthcare and Family

Services, will be available at the end of your case when you receive the HFS 3268 Notification of

Case Closure.  Requests can be made by returning the Response page of the HFS 3268 to the address

provided on the form.  The box asking the Department to review your case to assess interest should

be checked.

For someone requesting IV-D services after emancipation of the youngest child, a written request for interest adjudication

must be made within one year after applying for IV-D services and the request must meet the required criteria, including the 

criteria that a written request for interest must be received by the Department within one year of qualifying for 

interest enforcement.

Note:  Interest payments are not considered child support payments and are taxable as interest

Interest Payments

Interest is not paid until all principal balances are satisfied.  Although interest is collectible

as if it were child support, it is not the same as child support debt.  It is

considered to be “income” to the family.  In accordance with the Internal Revenue Code, payments

sent to the custodial parent on interest balances are taxable.

Therefore, at the end of January each year, Custodial Parents may be sent as many as

two IRS Form 1099‐INT statements for interest paid of $600.00 or more during the previous

tax year. The Department of Healthcare and Family Services (HFS) will send IRS Form

1099‐INT for interest paid through the SDU and the Comptroller will send IRS Form 1099‐ INT for

interest paid through their office.   (Note:  The Comptroller’s office sends out their IRS Form

1099 on interest payments of $10.00 or more.)

To determine if the $600.00 threshold is met, the total combined interest paid through the SDU and

interest paid through the Comptroller must be added together. The threshold is not $600.00 for the

Comptroller and $600.00 through the SDU. It is $600.00 total.

Interest on child support debt cannot be collected through the following OCSE Federal Offset

Program (FOP).

  • Federal Income Tax Refund Offsets.
  •  Administrative Offsets (vendor payments, federal retirement payments, miscellaneous payments).
  •  Passport Denial payments,
  •  MSFIDM payments.

The expansion of the FOP to include Administrative Offset, Passport Denial, and MSFIDM was only for

the purpose of assisting in the collection of delinquent child support debts. Since interest is not

child support, these remedies cannot be used for the collection of interest.

Interest Rate

There is a 9% annual interest rate on past-due child support in Illinois.  When adjudicated

interest calculations of Interest are completed, interest will be calculated by applying

one-twelfth of the statutory interest rate (9% divided by 12 months = .0075) to the

unpaid support balance at the end of each calendar month.
