South Dakota Bill of Sale Requirements
South Dakota handles vehicle titling through the Department of Revenue Motor Vehicle Division and the county treasurer offices. This page covers where a bill of sale fits in a private sale.
South Dakota requirements
- The South Dakota Department of Revenue tells sellers that, in addition to the title, the party selling a vehicle should provide the purchaser with a bill of sale. It is standard practice rather than a document the state issues to you.
- Titles must be updated within 45 days of the purchase date. The Department of Revenue charges interest on late motor vehicle excise tax after 45 days and adds a one-time penalty on applications made after 60 days.
- Applications for title and registration are made through the county treasurer using the Motor Vehicle or Boat Title and Registration Application, which has to be signed by the record owner or an authorized agent.
- South Dakota publishes its own Bill of Sale, Form 1025, through the Department of Revenue online forms portal. Our template is a general-purpose alternative you can use for items the state form does not cover.
- The Department of Revenue notes that damage disclosure at the point of sale has not been mandated since July 1, 2015, and points buyers to NMVTIS for odometer and brand history. Federal odometer disclosure rules still apply to the title assignment.
- The Department of Revenue does not list notarization as a requirement for the bill of sale itself. Confirm signing and document requirements with your county treasurer before the appointment.
