Beginning July 1, 2017, Illinois will begin using an income-share approach for child support. The Income Shares Model is based on the concept that children should receive the same proportion of income they would have received if the family remained intact.
To calculate child support under the income shares model, the income of both parents is first determined and combined. A basic child support obligation is set based upon economic estimates of average intact families with similar income and number of children. These estimated expenses account for the basic child support obligation, and can be adjusted for additional expenses such as healthcare, education or extracurriculars.
The child support obligation is prorated between the parents, and the parent who owes more support pays the difference to the other parent. However, if a parent has at least 146 overnights (approximately 40%) per year, their child support obligation may be adjusted or reduced. The income shares model will have a significant impact on cases where parenting time is shared.
