Understanding Child Support in Illinois
What is Child Support and Why Does it Matter?
Child support is a crucial aspect of family law, designed to ensure that children receive the financial support they need from both parents, regardless of the parents' relationship status. In Illinois, child support is mandated by law and is intended to cover the basic needs of the child, including housing, food, clothing, healthcare, and education. Ensuring that both parents contribute fairly to these expenses is essential for the child's well-being.
At Chicago Family Attorneys, we understand the importance of securing a fair child support arrangement that prioritizes your child's needs.

Illinois Child Support Guidelines and Calculations
Illinois uses the income shares model to calculate child support, which is considered one of the fairest approaches to ensuring that a child's financial needs are met. This model takes into account the combined income of both parents, reflecting the idea that children should benefit from the same level of financial support they would have received if their parents had remained together. The goal is to ensure that the child’s standard of living is maintained as much as possible, regardless of the changes in family dynamics.
How the Income Shares Model Works
The income shares model starts by determining the combined net income of both parents. This involves calculating each parent's income from all sources, including wages, bonuses, commissions, investments, and other income streams. The Illinois Department of Healthcare and Family Services provides guidelines that outline the basic child support obligation based on this combined income and the number of children involved. The idea is to replicate the percentage of parental income that would have been allocated to the child if the family were intact.
Once the combined income is established, the child support obligation is divided between the parents in proportion to their respective incomes. For instance, if one parent earns 60% of the combined income and the other earns 40%, the child support obligation will be divided accordingly. This proportional division ensures that both parents contribute fairly to the child’s financial needs.
Child Custody Can Influence Child Support Calculations
While the income shares model provides a structured approach, calculating child support can become complicated when unique circumstances arise. For example, parents with fluctuating incomes, such as those who are self-employed, work on commission, or have seasonal jobs may find it challenging to determine a consistent income level for the purpose of child support. In such cases, the court may look at income trends over a longer period to arrive at a fair and accurate calculation.
Another factor that can complicate child support calculations is shared or split custody arrangements. In situations where the child spends a significant amount of time with each parent, the standard child support calculation may need to be adjusted to reflect the actual parenting time. This can lead to more complex negotiations and require a detailed understanding of how the law applies to varying custody scenarios.
Beyond basic income and custody arrangements, there are other factors that may influence the child support amount. For example, the court may consider additional expenses such as healthcare costs, educational needs, and extracurricular activities. These costs can be substantial, and it’s important that they are accurately accounted for in the child support calculation. The court may also take into account whether one parent is paying for the child's health insurance or other necessary expenses.
Our Child Support Services in Chicago, Illinois
At Chicago Family Attorneys, we represent parents in every type of child support matter throughout Chicago and Cook County. From establishing new child support orders to modifying existing ones or enforcing unpaid support, our team provides knowledgeable guidance, affordable fees, and courtroom experience. We focus on protecting your rights while working to see that your child’s needs are met.
Establishing Child Support Orders
When parents divorce, separate, or establish paternity, the court must create a child support order. Illinois law follows the Income Shares Model under 750 ILCS 5/505, which bases support on the combined net income of both parents and allocates it according to each parent’s percentage of that income. This approach ensures children receive the same proportion of financial support they would have if both parents lived together.
Our attorneys calculate income accurately, apply the Illinois Department of Healthcare and Family Services Schedule of Basic Child Support Obligations, and factor in parenting time, health insurance, childcare, and extraordinary school or activity costs. When both parents have at least 146 overnights per year, the law requires the shared parenting formula, which multiplies the basic obligation by 150 percent and adjusts it according to parenting time.
We work to make sure these calculations are correct so your order reflects your child’s best interests.
We handle the filing of initial petitions in Cook County Circuit Court, use the Illinois Gross to Net Conversion Table when needed, and negotiate agreements to avoid costly litigation whenever possible.
Enforcing Child Support Court Orders in Cook County
Unpaid child support can cause significant hardship. Illinois courts and the Department of Healthcare and Family Services have strong enforcement powers under state law. Common enforcement tools include:
-
Income withholding orders that require an employer to deduct child support directly from a parent’s paycheck under the Income Withholding for Support Act
-
Judgments for arrears and statutory interest on overdue support
-
Driver’s license suspensions and even suspension of professional or occupational licenses for delinquent payors
-
Tax refund interception and liens against property
-
Contempt proceedings that may result in fines or jail for willful nonpayment
Our child support enforcement attorneys in Chicago use every available legal remedy to pursue what is owed and support your child’s financial stability.
Defending Against Unfair Child Support Claims
Sometimes child support orders are calculated incorrectly or unfairly. Parents may be ordered to pay more than the law requires because of overstated income, missed deductions, or misapplied parenting time formulas. We review income records, apply multi-family adjustments where a parent supports other children, and ensure maintenance is properly considered.
Illinois law also credits a child’s Social Security dependent benefits toward the paying parent’s obligation, and we work to make sure these credits are applied correctly. Our attorneys challenge inflated or inaccurate calculations so your child support order reflects what the law actually requires.
When Courts Deviate From Guidelines
Although Illinois courts generally follow the child support guidelines, 750 ILCS 5/505 allows a judge to deviate when applying the guidelines would be inequitable, unjust, or inappropriate. Courts must provide written reasons for any deviation. For example, a judge may increase support if a child has extraordinary medical needs, or adjust downward if strict application would cause undue hardship. Our attorneys present evidence to argue for or against deviations, depending on your circumstances.

Frequently Asked Questions About Child Support in Chicago, Illinois
How is child support calculated in Illinois?
Illinois calculates child support using the Income Shares Model under 750 ILCS 5/505. The court combines the net income of both parents, applies the Schedule of Basic Child Support Obligations published by the Illinois Department of Healthcare and Family Services, and allocates support based on each parent’s percentage of the total income. Parenting time, health insurance, childcare, and extraordinary educational or extracurricular expenses may also affect the final amount.
What is considered net income for child support in Illinois?
Net income includes wages, salary, bonuses, commissions, and other forms of compensation minus allowable deductions. Parents may use the Illinois Gross-to-Net Conversion Table or individualized tax figures to calculate net income. Courts also consider spousal maintenance received or paid, existing child support obligations for other children, and Social Security benefits that are payable to the child.
Can child support be modified in Cook County?
Yes. Under 750 ILCS 5/510, child support may be modified if there is a substantial change in circumstances. This could include a parent’s job loss, a significant increase in income, a change in parenting time or overnights, new childcare or medical expenses, or the emancipation of a child. Our Chicago child support modification lawyers file petitions in Cook County Circuit Court to increase, decrease, or terminate support based on your situation.
What happens if a parent does not pay child support in Illinois?
Failure to pay child support can result in serious legal consequences. Courts and the Department of Healthcare and Family Services may:
-
Issue a judgment for arrears with statutory interest
-
Enter an income withholding order requiring employers to deduct child support directly from wages
-
Suspend driver’s licenses or professional licenses for delinquent parents
-
Intercept tax refunds or place liens on property
-
Hold a parent in contempt of court, which may include fines or jail time
Our child support enforcement attorneys in Chicago use every available remedy to collect unpaid support.
Does shared parenting affect child support in Illinois?
Yes. If each parent has at least 146 overnights per year, Illinois law applies the shared parenting formula. In this calculation, the basic child support obligation is multiplied by 150 percent, then divided between the parents based on income and offset by the percentage of time the child spends with each parent. This often reduces the paying parent’s obligation but does not eliminate it.
Can Social Security benefits reduce child support?
Yes. If a child receives Social Security dependent benefits due to a parent’s disability or retirement, those benefits may be credited toward that parent’s child support obligation. Courts apply this credit to avoid double counting, ensuring the child’s needs are met while preventing overpayment by the parent.
How long do child support obligations last in Illinois?
Child support typically continues until the child turns 18 years old or graduates from high school, whichever is later, but not beyond age 19. Courts may also order parents to contribute to college expenses under 750 ILCS 5/513, which covers tuition, housing, and other educational costs.
What if I have children from another relationship?
Illinois law allows multi-family adjustments to account for other child support obligations. If you are already paying support for children from another relationship, those payments may reduce your available income for calculating new child support. Courts distinguish between court-ordered support and actual support paid without an order.
Do I need a lawyer for child support in Chicago?
While parents can attempt to calculate support on their own, Illinois child support laws are complex and mistakes can be costly. Hiring a Chicago child support lawyer can help ensure that income, deductions, parenting time, and credits are applied correctly. Our attorneys also represent you in negotiations and court hearings, protecting your rights and your child’s best interests.
