Child Support in South Dakota
South Dakota calculates child support under South Dakota Codified Laws sections 25-7-6.2 through 25-7-6.17. These set out an income shares style guideline. It combines both parents' monthly net incomes and applies a statewide schedule to the combined total. The resulting obligation is then divided between the parents, based on each one's share of the combined income. A South Dakota support order can be set as part of a circuit court divorce, custody, or paternity case. Or a parent can apply through the Division of Child Support, part of the Department of Social Services. That division is the state's IV-D agency. South Dakota circuit courts hear contested child support matters. The Division of Child Support can also set up and enforce orders administratively, including through an online support calculator the division publishes.

The South Dakota guideline formula
Under SDCL 25-7-6.2 and the sections that follow, South Dakota combines both parents' monthly net incomes. It finds the basic obligation the statutory schedule assigns to that combined amount. Then it divides the obligation between the parents, proportional to their income share.
The statute addresses health insurance costs and work-related child care expenses as part of the overall calculation.
Applying through the Division of Child Support
The South Dakota Division of Child Support sits inside the Department of Social Services. It is the state's IV-D agency. A parent can apply through the division for paternity establishment, a support order, or enforcement.
The division also publishes an online support calculator. Parents can use it to estimate an amount before or during a case.
Which court hears the case
South Dakota circuit courts hear contested child support matters connected to divorce, custody, and paternity cases. The Division of Child Support can also set up support administratively in many IV-D cases. A parent can request a circuit court hearing when a case is contested.
Modifying a South Dakota order
A South Dakota order can be modified after a substantial change in circumstances since it was set. A significant income change is one example. The Division of Child Support periodically reviews orders it enforces. It can pursue modification when reapplying the statutory schedule to current income produces a materially different amount.
A parent seeking modification files with the circuit court that issued the order, or requests a review through the division for agency-managed cases.
Enforcement
The Division of Child Support enforces South Dakota orders using standard IV-D tools. These include income withholding, intercepting state and federal tax refunds, credit bureau reporting, and license suspension for significant arrears.
A parent owed support who needs enforcement help can open a case with the division. This works even when the original order came from a private circuit court filing.
