SSI Eligibility Requirements
State SSI Supplement in South Dakota
South Dakota does not provide a state supplement to federal SSI benefits. Recipients receive only the federal SSI payment amount.
Medicaid Coordination
South Dakota has not expanded Medicaid. SSI recipients may still qualify for Medicaid, but eligibility is determined separately through SSI recipients automatically qualify for Medicaid in South Dakota (Section 1634 state); South Dakota did not expand Medicaid under the ACA until voters approved Amendment D in 2022, effective July 2023.
Applying for SSI
You can apply for SSI at your local SSA field office in South Dakota (locations include Sioux Falls, Rapid City, Aberdeen, Watertown, Huron, Mitchell). You can also start your application online at ssa.gov or by calling SSA at 1-800-772-1213.
