Can I be Put in Jail for Not Paying Child Support in Illinois?
By: Gordon & Perlut, LLC
In cases of divorced or unmarried parents, having a valid child support order in place is vitally important. In addition to helping to ensure parents get timely payments and the maximum amount they are entitled to and need to provide for their child, it also gives them legal recourse in the event the other parent fails to pay their share.
Child support enforcement is a serious matter in Illinois. The Chicago and Skokie child support attorneys at Gordon & Perlut, LLC explain how child support is calculated and the penalties you could face for non-payment, which include a potentially lengthy jail sentence.
Under the Illinois Statutes (750 ILCS 5/505), the state goes by an income shares model to determine child support amounts, using the following formula:
What if you are unable to find a job or work under the table? Do you still have to pay child support? Yes. The court will impute an amount based on your skills, experience, and prior earnings. If you continue not to pay, you can be held in contempt of court.
Under state laws, parents have a legal duty to provide financially for their children. Can you be put in jail for not paying child support in Illinois? The answer is a resounding yes. It can and does happen on a regular basis. You can be put in jail for contempt of court and may remain there until you pay any outstanding child support amounts owed. You can also be subject to other penalties both through the state and through the U.S. Department of Health and Human Services (HHS). These include:
The most frequent consequence is civil contempt of court. When a parent fails to follow a court‑ordered support obligation, the court may find them in contempt and order a “purge” payment—an amount the parent must pay to avoid further penalties. Courts must set the purge based on the parent’s ability to pay, not the full amount owed.
If the parent does not pay the purge, the judge may impose:
Civil contempt is designed to force compliance, not punish.
Yes. Illinois imposes 9% annual interest on any child support that remains unpaid at the end of each month. Each missed monthly payment is treated as a separate judgment, so interest is calculated individually for every delinquent installment.
This means arrears can grow quickly, especially for long‑term nonpayment.
Yes, but jail is typically a last resort. Jail time usually occurs only after:
Illinois courts generally give parents opportunities to catch up before ordering incarceration.
Yes. Illinois can intercept:
This is a common enforcement tool used to reduce arrears and is often triggered automatically when a parent falls behind.
Yes. Illinois may suspend:
These suspensions are used to pressure delinquent parents into compliance.
Yes. If arrears exceed $2,500, the federal government may deny a passport application or renewal. This is part of federal enforcement and applies nationwide.
Yes. In addition to civil contempt, Illinois law allows criminal prosecution for willful nonpayment. This is less common but can occur when a parent intentionally avoids paying despite having the ability to do so.
Penalties may include:
Absolutely. Illinois courts and the Department of Healthcare and Family Services (HFS) can:
These tools help ensure consistent payment.
If your financial circumstances have changed—job loss, disability, reduced income—you must petition the court for a modification. Illinois does not forgive past‑due support, but it can adjust future payments.
Failing to pay without seeking modification can still result in penalties, even if the hardship is real.
Illinois can enforce child support indefinitely. There is no statute of limitations on collecting arrears, and interest continues to accrue until the balance is paid.
