The Department of Social Services conference room in Pierre was nearly empty when Secretary Matt Althoff announced the obvious in July 2025. South Dakota’s SDCareerLink waiver proposal was now “an exercise in futility.” Federal work requirements signed July 4 had rendered the state’s independent approach moot. South Dakota had developed deliberately modest verification: annual attestation without monthly hour tracking, qualitative participation standards. The state wanted work requirements but not the administrative apparatus to enforce them. OBBBA mandated precisely what South Dakota sought to avoid: 80 hours monthly, semi-annual redeterminations, upfront compliance verification.
The state formally withdrew its waiver application July 23, 2025. South Dakota operates Medicaid expansion with 27 fewer staff positions than initially projected because enrollment fell short. The Department eliminated positions for lack of work. Now that same department must build federal compliance infrastructure by December 2026. The state’s preferred path, relationship-based navigation with minimal verification technology, collides with federal requirements assuming automated data systems.
This tension between state capacity and federal mandate defines South Dakota’s implementation challenge. The state expanded because voters demanded it through Constitutional Amendment D in 2022 (56-44%), then authorized work requirements through Constitutional Amendment F in 2024 (also 56-44%). The legislature never enthusiastically supported expansion, viewing it as voter imposition. Work requirements represent legislative response to an expansion they never wanted.
Ballot Initiative Sequence#
Constitutional Amendment D in November 2022 mandated Medicaid expansion to 138% FPL effective July 1, 2023. The citizen initiative bypassed a legislature and governor who had rejected expansion repeatedly. The 56-44 margin was substantial. The measure included no work requirements.
The legislature’s response came through Constitutional Amendment F, placed on the November 2024 ballot. The measure authorized work requirements for expansion adults contingent on federal approval. The amendment passed 56-44, identical margin to expansion itself. Both policies carry ballot legitimacy.
The SDCareerLink proposal released for public comment in May 2025 proposed annual verification at renewal, qualitative participation standards without specific hourly thresholds, and self-attestation. The Department projected 5-10% enrollment reduction, translating to 1,500-3,000 coverage losses from April 2025 enrollment of 30,542. Federal preemption ended the state’s independent approach.
State Capacity and Economic Paradox#
South Dakota operates Medicaid with staffing levels appropriate for 920,000 residents and approximately 134,000 Medicaid enrollees. The state budget constrains expansion of administrative capacity. The SDCareerLink proposal explicitly noted work requirements had to be implemented “within an existing budget.” The $200 million congressional allocation for implementation funding across all states provides limited per-state resources.
The paradox: the state maintains the nation’s lowest unemployment rate at 1.8-1.9%. Jobs are abundant, employers actively recruiting. The Department estimated 80% of expansion enrollees already work or qualify for exemptions. If four-fifths of the population complies without enforcement, work requirements function primarily as documentation systems for people already employed. The behavioral change theory underlying work requirements assumes slack labor markets. South Dakota faces the opposite: tight labor markets where anyone who can work already has strong financial incentives.
The state’s small scale creates distinctive implementation dynamics. With 30,542 expansion adults as of April 2025, South Dakota could theoretically provide personalized navigation to every member. Whether federal regulations permit such approaches, and whether South Dakota chooses to invest in them, determines whether small population becomes advantage or disadvantage.
Geographic and Tribal Challenges#
South Dakota has counties with populations under 1,000, no workforce development offices, limited broadband access, and minimal public transportation. Implementing uniform verification in both Sioux Falls (population 213,000) and Jones County (population 917) requires different approaches. The same verification process that functions in urban contexts fails in extreme rural settings.
Nine federally recognized tribes create implementation considerations around sovereignty and IHS exemptions. OBBBA exempts individuals eligible for IHS services from work requirements. This creates clear legal framework but requires operational implementation. States cannot verify IHS eligibility without tribal cooperation.
Pine Ridge Reservation illustrates scale of potential exemptions. With approximately 28,000 enrolled tribal members and unemployment rates exceeding 70%, most expansion adults would qualify for IHS exemptions. Rosebud, with approximately 26,000 residents, faces comparable circumstances. These two reservations alone could account for thousands of automatic exemptions if verification systems properly identify IHS eligibility.
Implementation and Bottom Line#
South Dakota will implement federal work requirements by December 2026 using the least administratively complex approach federal regulations permit. If federal guidance allows annual attestation-based verification, South Dakota adopts that model. If federal regulations mandate monthly hour tracking and semi-annual verification, South Dakota must build or contract for automated systems the state neither budgeted nor planned. Tribal coordination determines whether thousands of IHS-eligible individuals receive automatic exemptions or face inappropriate verification.
The state’s extremely low unemployment rate means behavioral effects will prove minimal. Coverage losses will reflect verification failure, not employment failure, given the state’s estimate that 80% already comply or qualify for exemptions. Small-state personalization could compensate for small-state capacity constraints if South Dakota chooses to invest in navigation support. Whether the state builds such infrastructure or relies on members to navigate systems independently determines whether small scale becomes advantage or disadvantage. In a labor market operating near full employment, work requirements cannot substantially increase work already occurring. They can, however, substantially reduce coverage among people working informally or unable to navigate documentation requirements despite actual compliance. December 2026 approaches with verification infrastructure yet to be built.
