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.
What South Dakota itself adds to the cost of a delivery car
Before insurance, fuel or depreciation, a state takes its own cut of putting a car on the road, and the amount is not uniform. South Dakota charges 4 percent vehicle sales tax. Base registration runs $36 a year and the title fee is $10. Registration recurs every year the car is on the road; sales tax and title are paid once and belong spread across the years the driver keeps it, not charged to whichever month they happened to fall in.
These are small numbers next to insurance, and they are worth stating precisely anyway, because an actual-cost standard is built out of exactly this kind of line. The calculator below applies South Dakota's own published rates to a vehicle price and a driver's mileage, using the business use share the IRS publishes at Rev. Proc. 2019-46 sec. 6.02(9). That table is keyed to annual business mileage alone, which is the one figure a delivery POS already reports, so it needs nothing from the driver.
Note what the mileage control does. The same fees spread over 8,000 miles cost materially more per mile than over 25,000, because they do not shrink when the car is driven less. That is true of every fixed cost a driver carries, and it is why a single rate across a mixed roster underpays the part-time drivers, who are also the drivers closest to the wage floor.
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.
The South Dakota translation: run the cheap-state trade, and put a January review on the calendar, because South Dakota is the floor-tier state whose reference line actually moves. The 10-point self-audit takes two minutes.
