Understanding South Dakota's Child Support Formula
South Dakota uses the Percentage of Income model, one of the simpler child support approaches in the United States. The court converts the paying parent's gross monthly income to net income by applying a 76% factor that accounts for estimated taxes and mandatory payroll deductions. That net income figure is then multiplied by a fixed percentage that increases with each additional child:
| Children | % of Net Income | Monthly at $5,000 gross |
|---|---|---|
| 1 child | 17% | $646/mo |
| 2 children | 25% | $950/mo |
| 3 children | 29% | $1,102/mo |
| 4 children | 31% | $1,178/mo |
| 5 children | 34% | $1,292/mo |
South Dakota caps the paying parent's net income at $10,000/month for guideline calculations. A parent earning above approximately $13,158/month gross will have their obligation calculated from the cap rather than their actual income. Courts retain discretion to order additional support above the cap for high earners in cases involving extraordinary expenses.

South Dakota Child Support, Frequently Asked Questions
What percentage does South Dakota use for child support?
South Dakota uses 17% of adjusted net income for one child, 25% for two children, 29% for three, 31% for four, and 34% for five or more children. These percentages apply to the paying parent's net income after a 76% conversion factor for taxes.
Is there an income cap for child support in South Dakota?
Yes. South Dakota caps the paying parent's net income at $10,000/month (approximately $13,158/month gross) for guideline calculations. Income above this threshold does not increase the standard obligation. However, a judge can order additional support beyond the cap in cases where the child has extraordinary needs, such as private schooling, medical conditions, or significant extracurricular costs, or where the paying parent earns substantially more than the cap.
What is the average child support payment in South Dakota?
Child support awards in South Dakota typically range from $350–$750/month based on current data. The actual amount varies significantly depending on both parents' incomes, the number of children, custody arrangements, and whether costs like health insurance or childcare are included in the order. Higher income households and multiple children will produce awards above this range.
Can a South Dakota judge order a different amount than the calculator shows?
Yes. The South Dakota guidelines produce a presumptive amount — the starting point, but a judge can deviate from it when following the guidelines would be unjust or inappropriate in a specific case. Common reasons for deviation include extraordinary medical or educational expenses, one parent directly paying significant healthcare premiums, a parent's substantial assets or non-wage income, the needs of children from other relationships, or significant travel costs related to custody exchanges.
How do you modify a child support order in South Dakota?
Either parent can petition the South Dakota court to modify an existing child support order when there has been a substantial change in circumstances. This typically means a significant change in either parent's income (usually 15–20% or more), a change in custody or parenting time, the child developing extraordinary medical or educational needs, or a change in the cost of health insurance. Most states, including South Dakota, also allow automatic review every three years if either party requests it, even without proving a substantial change.
When does child support end in South Dakota?
In South Dakota, child support terminates at: Age 18 or high school graduation, whichever is later. The governing law is SDCL § 25-7-6.2, administered by the DSS Division of Child Support. If you have an existing order and believe your child is approaching the termination age, contact DSS Division of Child Support or your family law attorney to confirm the specific end date and ensure a formal termination order is entered.
