Child Support

What is an example of a guideline for child support based on the income of only the noncustodial parent?

On page 83 is a comparison chart showing the "percentage of obligor's income" guidelines that were in effect in Illinois and in New York in the year 2003:

Percentage of Obligor's Income Guidelines

Number of children Percent of supporting party's net income
Illinois New York
1 20% 17%
2 28% 25%
3 32% 29%
4 40% 31%
5 45% 35% for 5 or more children
50% for 6 or more children

Under this guideline, if a noncustodial parent (supporting party) in Illinois had a net income of $40,000, the annual level of child support would be $8,000 for one child; $10,000 for two children; $12,800 for three children; and so on.
