How much someone has to pay for child support in Illinois depends on the net income of the person paying and the number of kids being supported. Child support is based on a percentage of net income and it goes like this:
Number of Kids Percentage of Net Income
6 or more 50%
While there has been talk about changing Illinois child support laws, this is current as of this writing in July 2013.
