Illinois uses the Income Shares Model with annual schedule updates to ensure fair, consistent child support calculations
Illinois law (750 ILCS 5/505) establishes a systematic approach to child support calculation implemented across all Circuit Courts.
Step 1: Calculate each parent's combined monthly net income (all sources minus allowable deductions).
Step 2: Use the Schedule of Basic Obligations to find the base support amount based on combined income and number of children.
Step 3: Divide the base obligation between parents based on their proportional share of combined income.
Step 4: Add proportional allocations of health insurance, childcare, and medical expenses.
Step 5: Adjust for tax considerations and any additional factors under Illinois law.
Start with gross income from all sources (wages, self-employment, bonuses, rental income, etc.) and subtract all allowable deductions to determine net income for both parents.
Illinois maintains an updated Schedule of Basic Obligations based on combined net income level and number of children. Updated annually in March.
Each parent pays a percentage of the base obligation equal to their percentage of combined net income.
Health insurance premiums, childcare costs, and extraordinary medical expenses are allocated proportionally and added to base support.
Illinois law allows courts to deviate from guidelines based on factors like parenting time, financial hardship, and other statutory considerations.
The Schedule is updated each March to reflect changes in living costs and economic conditions. Always verify the current year's table.
