South Carolina Child Support FAQ

How is child support calculated in South Carolina?

South Carolina uses the income shares model under S.C. Child Support Guidelines (DSS): both parents’ incomes are combined, a basic obligation is determined, and each parent is responsible for their proportional share. The paying parent’s share becomes the support order.

Does South Carolina use gross or net income for child support?

South Carolina calculates support on gross (pre-tax) income as defined in S.C. Child Support Guidelines (DSS).

Can a South Carolina court order more or less than the guideline amount?

Yes. The guideline amount under S.C. Child Support Guidelines (DSS) is presumptive, not absolute - courts may deviate with written findings for factors like extraordinary medical or educational needs, other children supported, or very high income beyond the guideline range.

How do I apply for or modify child support in South Carolina?

Apply through the South Carolina child support agency or the family court in your county. Existing orders can be modified on a substantial change in circumstances - typically a significant income change, job loss, or a change in custody. The official calculator/worksheet is linked on this page (dss.sc.gov).
