Illinois Child Support Guidelines: The Income Shares Model

Illinois uses the Income Shares Model to calculate child support. This approach considers the combined income of both parents and estimates what they would spend on their child if they lived together. The total support obligation is then divided proportionally based on each parent’s income.

Key factors include:

  • Each parent’s gross income
  • Number of children
  • Parenting time (overnights per year)
  • Health insurance premiums
  • Childcare expenses
  • Other support obligations

This model aims to reflect the child’s standard of living had the parents remained together.

Step-by-Step Breakdown of the Calculation

Here is how child support is typically calculated in DuPage County under Illinois law:

1. Determine Gross Income

Gross income includes wages, bonuses, commissions, rental income, and other sources. Certain deductions, like taxes and mandatory retirement contributions, may be considered.

2. Combine Parental Income

The court adds both parents’ gross incomes to determine the total household income.

3. Apply the State Schedule

Illinois publishes a schedule of basic child support obligations based on combined income and number of children. This schedule estimates the total monthly cost of raising the child.

4. Divide the Obligation

Each parent’s share of the total support obligation is calculated based on their percentage of the combined income.

5. Adjust for Parenting Time

If both parents have at least 146 overnights per year, the court may apply a shared parenting adjustment, which reduces the paying parent’s obligation to reflect their direct expenses during parenting time.

6. Add Additional Expenses

The court may include costs for:

  • Health insurance premiums
  • Uninsured medical expenses
  • Childcare
  • Extracurricular activities

These are typically split proportionally between the parents.

Modifying Child Support Orders

Child support orders in DuPage County can be modified if there is a substantial change in circumstances, such as:

  • Job loss or income change
  • Change in parenting time
  • Medical needs of the child
  • Relocation of either parent

To request a modification, you must file a petition with the DuPage County Circuit Court and provide evidence supporting the change. Modifications can be tricky, so it is best done with the help of an experienced Illinois family law attorney.

Enforcement of Child Support
