For child support orders entered after July 1, 2017, Illinois courts apply the income shares model to calculate child support. This formula considers the income of both parents. The court uses the economic tables to determine the appropriate amount of child support and then apportions this support between the parents in proportion to their income. For example, if the child support amount is $1,000 and the mother earns $40,000 and the father earns $60,000, the father would be responsible for $600 of this support. Attorney Michael Strauss was a co-author of the new statutes in Illinois.
