Calculating Child Support In Chicago: The Illinois Income Shares Model Explained
If you are going through a divorce or working out child support, you may wonder how child support is calculated in Illinois. Many parents start with an Illinois child support calculator. These tools can give you a general estimate, but the final amount depends on several legal and financial factors.
Illinois courts use the Illinois Income Shares Model. The model considers each parent’s income, parenting time and certain costs related to raising a child.
At Lake Toback DiDomenico, our Chicago family law lawyers help parents understand how Illinois child support laws apply to their situation. We provide clear guidance based on your family’s needs so you can make informed decisions about your future.
How The Income Shares Model Works: Combining Both Parents’ Net Incomes
Illinois uses the Illinois Income Shares Model to calculate child support. The law looks at both parents’ net incomes instead of relying on only one parent’s earnings. The goal is to estimate what both parents would have spent on their child if they still lived together.
The court combines both net incomes and applies the Illinois child support guidelines. Each parent usually pays a share of the support based on their percentage of the combined income.
Online tools can estimate child support, but they cannot account for every family’s financial situation.
The Shared Parenting Threshold: How 146 Overnights Changes the Calculation
Illinois considers a case to involve shared parenting when each parent has at least 146 overnights with the child each year. Once parenting time reaches that threshold, the child support calculation changes.
The court no longer relies on the standard formula alone. Instead, it considers both parents’ incomes, the parenting schedule and other factors to determine each parent’s financial responsibility.
The court may also consider:
- Each parent’s net income
- The number of overnights each parent has
- The child’s financial needs
- Other child-related expenses
If you have questions about shared parenting time and child support in Illinois, our attorneys can explain how your parenting schedule may affect your support obligation.
Calculating Net Income: Acceptable Deductions And Hidden Complexities
Net income is not always easy to calculate. Illinois law starts with gross income and allows certain deductions before determining each parent’s net income.
Income may come from:
- Wages or salary
- Bonuses or commissions
- Self-employment or business income
- Investment or retirement income
- Other sources of income
These income sources can make child support calculations more complicated, especially for business owners, physicians, executives, investors and other professionals.
Online estimates often cannot reflect those financial details. Our attorneys review your financial information and explain how the Illinois Income Shares Model may apply to your situation.
Beyond The Basic Obligation: Extracurriculars, Childcare And Uninsured Medical Expenses
Child support often includes more than a monthly payment. Illinois courts may divide additional child-related expenses between the parents.
These costs often include:
- Work-related childcare
- Health insurance premiums
- Uninsured medical, dental and vision expenses
- Extracurricular activities
- Certain educational expenses
Courts divide these expenses based on each parent’s financial circumstances.
Understanding the Cook County child support guidelines means looking beyond the basic formula. Parents should also understand how courts allocate these additional costs when making child support decisions.
An Illinois Child Support Calculator Cannot Replace Legal Guidance
An Illinois child support calculator can provide a useful starting point, but it cannot evaluate the facts that make your family unique. It cannot account for disputed income, changing parenting schedules or complex financial issues.
Every family’s situation is different. At Lake Toback DiDomenico, we take the time to understand your circumstances and guide you through the child support process. We explain how Illinois law applies to your case so you can make informed decisions about your future.
