In almost all cases the non-custodial parent will be required to pay child support to the other parent. Illinois uses a system of minimum child support guidelines which are expressed in terms of a percentage of the support paying parent’s net income.
1 child : 20% of net income.
2 children : 28% of net income
3 children : 32% of net income
4 children : 40% of net income
The guidelines are minimum guidelines. A court will often require the non-custodial parent to contribute to the cost of medical and dental expenses not covered by insurance, extracurricular activity expenses and day care expenses. Depending on the facts of the case, a court can require a parent to contribute to the cost of parochial or private school education. In cases where payment of guideline support would result in a windfall to the custodial parent, the court can deviate downward from the guidelines and order support based upon the needs of the children. Child support is not tax-deductible to the parent paying the support.
