SSI in South Dakota: state supplement, recipients and offices
In December 2025, 13,902 people in South Dakota got SSI, and SSA paid them $10.1 million that month. SSA pays no state supplement here; any extra money comes from the state itself.
Does South Dakota add money to SSI?
State supplement: n/d. South Dakota is not in SSA's January 2026 table of supplements that SSA pays for states. If South Dakota pays a supplement, the state pays it, not SSA, and we found no current official table for it. Ask the state agency that runs social services. For questions about SSI itself, call SSA at 1-800-772-1213.
