Illinois Child Support Overview
Calculation Model
Income Shares (schedule-based; changed from flat percentage model in 2017)
Income Basis
combined net income (both parents)
Formula Summary
Illinois adopted the income shares model effective July 1, 2017, replacing the prior flat-percentage model. Combined net income of both parents is used to look up base support obligation from a schedule. Each parent pays a proportional share. Parenting-time adjustment applies when each parent has the child at least 146 overnights.
