If you are facing a child support case in Mellette County, South Dakota, the first question is almost always the same: how much? The honest answer is that it depends on income, children, and parenting time, all run through South Dakota's statewide formula. Below you can see how that formula works and try it with your own numbers.

South Dakota follows the Income Shares model under S.D. Codified Laws § 25-7-6.1 et seq.. 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 Dakota runs the formula on net income, meaning income after taxes come out. Net monthly income, gross income from all sources reduced by federal and state taxes, FICA, mandatory retirement, mandatory union dues, dependent health insurance, and existing court-ordered support.

Parenting time matters directly in South Dakota: the number of overnights each parent has changes the math itself. South Dakota uses a shared-care formula, so parenting time can change the support number once a parent has the children for a meaningful portion of the year. When a parent has enough overnights to qualify, the court adjusts each parent's share of the basic obligation to reflect the time the children spend in each home. A standard schedule with one primary parent usually does not trigger a large shared-care adjustment. The calculator on this page only estimates the effect, and the official South Dakota worksheet controls how overnights are scored.

When does it end? South Dakota child support generally ends at age 18 but extends to age 19 if the child is still attending secondary school full time. Continuing support for disabled adult children is available.

Can the amount change later? File a motion in circuit court or request review through DCS. A 20% variance or 3-year review supports modification.

If payments fall behind, South Dakota has real enforcement tools. South Dakota DCS enforces through immediate income withholding, tax intercept, license suspension, lien filings, credit reporting, and contempt referrals.
