Not all money received is used to calculate "gross annual income" for the purposes of calculating child support. Below is a list of money received which will not be taken into account when calculating child support.

Income derived from child support payments actually received; 

Income derived from any public assistance program, eligibility for which is based on a determination of need;

Child support received by a party for children from another relationship;

Supplemental Security Income (SSI) benefits derive from a need-based program under which eligibility is tied to a person's status as aged, blind or disabled and income below certain statutory amounts.

The above exceptions will not be factored into gross annual income for calculating child support.
