South Dakota Mileage Reimbursement Law 2026: Cheap Miles Under an Indexed Floor
South Dakota separates itself from the rest of the floor tier with one word: indexed. Documented delivery costs sit with the nation's cheapest at roughly $0.41 to $0.44 per mile, but unlike Idaho or Iowa, South Dakota's minimum wage adjusts upward every January by ballot-enacted indexing, with the tipped wage riding at half. Cheap miles keep the compliant structure nearly free; the moving floor means the math behind it deserves an annual re-check the other cheap states never force.
The legal baseline
South Dakota adds no reimbursement duty; the FLSA kickback analysis runs against the indexed state floor, higher than federal and rising each January. The half-rate tipped structure keeps effective pay leaning on the credit toward that line, so at $0.42 documented cost, roughly $5.45 per hour of vehicle expense at typical pace, under-covering fees walk pay below a line that climbs annually. Parker persuades in the Eighth Circuit; the pattern is in our litigation roundup.
The cost landscape
- Sioux Falls and Rapid City set the top at $0.43 to $0.44.
- Aberdeen, Brookings, and the rest hold $0.41 to $0.43, per our 50-state table.
- The IRS default overpays by $0.32 to $0.35, roughly $4,800 to $5,250 per full-time driver per year.
