Child Support Calculator in South Dakota: What You Should Know
South Dakota uses the Income Shares Model under Chapter 25-7 of the state code, combining both parents' net incomes to set the basic obligation from a statutory schedule. The schedule lists the combined obligation by income and number of children, and each parent then covers a share in proportion to their income. South Dakota adds health insurance and childcare costs and provides a low-income adjustment for parents near the poverty level. There is no flat income cap.
Key point: South Dakota follows the Income Shares Model on net income, using the statutory schedule in Chapter 25-7 and prorating the obligation between the parents.

Child Support in South Dakota - Frequently Asked Questions
How is child support calculated in South Dakota?
South Dakota uses the Income Shares Model to calculate child support. Both parents' gross incomes are combined, and each parent's share of the total obligation is proportional to their share of the combined income.
Can child support be modified in South Dakota?
Yes. Either parent can request a child support modification if there has been a substantial change in circumstances, such as a significant change in income, change in custody arrangements, or changes in the child's needs. Courts in South Dakota typically require a change of at least 15-20% in the support amount to justify modification.
Does custody arrangement affect child support in South Dakota?
Yes. Parenting time is a significant factor in child support calculations. When a parent has the children for a substantial portion of time (typically 40% or more overnights per year), child support is adjusted to reflect the additional direct costs that parent bears.
Is there an income cap for child support in South Dakota?
South Dakota does not set a specific income cap in its child support formula. However, courts have discretion to deviate from the guideline amount in cases with very high incomes.
How long does child support last in South Dakota?
Child support in South Dakota typically continues until the child turns 18 or graduates from high school, whichever is later. Support may continue longer if the child has a disability or if the parents agree to extend support for college expenses.
