South Dakota Child Support Guidelines
South Dakota posts 82% of its Title IV-D caseload with an established order - thinner than two-thirds of reporting jurisdictions on OCSE P-64 (methodology and case-counting also move this share). The Income Shares schedule (43 jurisdictions on this model) opens lower than most peers before deviations.

One-child base rate at South Dakota's median income
17% of $63,920, the Census ACS 2022 median household income for South Dakota, divided across twelve months, 5% below the median state. An index for comparing states, not a case estimate: guidelines apply to the obligor's income, or to combined parental income under the Income Shares model, and a court sets the actual order. How this is derived.

Where South Dakota's one-child starting rate sits
Each bar counts states with a published one-child base rate in that 3-point band. South Dakota's lower-third 17% mark is highlighted. Counts are exact from the 51-jurisdiction dataset.
South Dakota's 17% published one-child base rate is higher than 6 of 51 recorded state rates. The comparison describes guideline starting percentages, not a complete child-support estimate. South Dakota sits in a lower-rate band on this histogram.

Thinner order-establishment share
South Dakota in the thinner-order third
South Dakota sits in the bottom third on OCSE P-64 order share (82% · #44 of 51).
South Dakota posts 82% of its Title IV-D caseload with an established order - thinner than two-thirds of reporting jurisdictions on OCSE P-64 (methodology and case-counting also move this share). The Income Shares schedule (43 jurisdictions on this model) opens lower than most peers before deviations. Unlike capped states, the formula applies to full reported income before deductions. Nearest one-child rate peer: Connecticut at 17% (Δ 0.0 pts). South Dakota allows a parenting-time adjustment when the non-custodial parent exercises substantial overnight time. A percentage figure alone does not determine the dollar amount - compare South Dakota to other guideline models →
On OCSE FY2023 tables, South Dakota ranks #44 of 51 on order-establishment share and #44 by caseload volume (~$2,322 distributed per case, our calc on P-4/P-52). Source: HHS Office of Child Support Services, FY 2023 Preliminary Report.
How South Dakota Calculates Child Support
South Dakota uses the Income Shares model. Both parents' incomes are combined, the total obligation is looked up from a schedule, then split proportionally based on each parent's income share. Its one-child base rate is in line with the national middle range. That lower-third starting rate is the schedule's open before deviations.
