Child Support in Marion County, South Carolina: How Much Will You Owe?

Working out child support in Marion County, South Carolina can feel like a black box. It is not. South Carolina publishes one guideline formula, and this page opens it up: what counts as income, how parenting time matters, and a live calculator so you can see where your case likely lands.

South Carolina follows the Income Shares model under S.C. Code § 63-17-470 and the SC DSS Child Support Guidelines. The court combines both parents' monthly gross incomes, looks up the basic support obligation on the state's guideline schedule for that income level and number of children, then prorates the obligation between the parents according to each parent's percentage share of the combined income.

What counts as income? South Carolina runs the formula on gross income, meaning income before taxes come out. Gross income from any source including wages, self-employment, bonuses, commissions, pensions, retirement, Social Security, workers' compensation, unemployment, and recurring gifts.

Parenting time matters directly in South Carolina: the number of overnights each parent has changes the math itself. South Carolina uses a shared-care formula when both parents have a meaningful amount of parenting time. Under the SC DSS Child Support Guidelines, the shared-custody calculation applies only when each parent has at least 110 overnights per year with the child. When that threshold is met, the worksheet adjusts each parent's share to reflect the divided time and the cost of keeping two homes. Below 110 overnights for a parent, the standard Income Shares worksheet applies and extra visitation alone does not automatically lower the support number.

When does it end? South Carolina child support generally ends at age 18 or upon high school graduation, whichever is later, but not past age 19. Continuing support for disabled adult children is available.

Can the amount change later? File a motion in family court or request review through CSSD. A substantial change in circumstances supports modification.

If payments fall behind, South Carolina has real enforcement tools. South Carolina CSSD enforces through immediate income withholding, tax intercept, license suspension, lien filings, credit reporting, and contempt with potential incarceration.
