Free South Dakota Car Bill of Sale
South Dakota pairs a flat vehicle tax — 4% excise, charged instead of sales tax, with no county or city able to add anything — with famously light residency requirements, which built its reputation among full-time RVers and out-of-state registrants. A standard private sale runs on the state bill of sale (Form 1025) and title application (Form 1001) at the county treasurer of the buyer's county of RESIDENCE (not where the car sits), inside a relaxed 45-day window, with no inspection of any kind. The 4% calculates from the price, and state law requires the bill of sale — without it, the excise is assessed on dealer-guide retail value — so it should carry the real number and an exact date.
