Several factors are considered in a child support calculation including, each parents income, the number of children, and the amount of parenting time each parent has with the child or children. Based on these factors each parent will be allocated a certain percentage of a predetermined basic child support obligation, as calculated by The Department of Healthcare and Family Services (“HFS”).
In short, HFS calculates the basic child support obligation by looking at the parent’s combined income and the number of children who will be receiving support. HFS has compiled a schedule of what the average Illinois household at each level of combined income ordinarily spends on their children.
Once the basic child support obligation is determined, responsibility for contributing to the obligation is allocated to each parent based on the percentage of each parent’s income relative to total income and the amount of overnight parenting time each parent has with the child or children. The allocation of each parent’s responsibility towards the basic child support obligation is determined by a formula contained in 750 ILCS 5/505.
Additionally, a court will often require the parents 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. Child support is not tax deductible to the parent paying the support.
