The Illinois Child Support Data Sheet is a document used to calculate the amount of child support payments for custodial parents in the state of Illinois. It is used by the Illinois Department of Healthcare and Family Services to calculate the amount of financial support a non-custodial parent must provide based on their income, the number of children involved, and other factors. The Data Sheet is divided into three parts: Basic Information, Income and Adjustments, and Calculation of Child Support. The Basic Information section of the Data Sheet contains information about the custodial and non-custodial parents, as well as the number of children involved in the situation. The Income and Adjustments section requires the non-custodial parent to provide information about their gross income, deductions, and other adjustments that may affect their child support payments. The Calculation of Child Supports section is used to calculate the amount of support that the non-custodial parent must pay. This section takes into account the incomes of both parents, the number of children involved, and other factors such as health insurance coverage and daycare expenses. There are two types of Illinois Child Support Data Sheet. The first is for parents who are paying support, and the second is for parents who are receiving support.
