Which South Dakota form goes with which deal

A form list on its own does not tell you what to grab on a Saturday afternoon. Here is the same set arranged by the deal in front of you.

Retail sale to a customer in state: Motor Vehicle/Boat Title & Registration Application (Form 1001), Odometer Disclosure (Form 1021), the FTC Buyers Guide, and a bill of sale. This is the stack behind almost every deal jacket you build.
Retail sale to an out-of-state buyer: Same paperwork, but the buyer titles in their home state, so the South Dakota title has to be assigned cleanly and the odometer reading has to match on every document. A correction later means a duplicate title and a delayed deal.
Wholesale to another licensed dealer: No Buyers Guide is required on a dealer-to-dealer sale, but the title assignment and odometer disclosure still are. Keep the invoice with the jacket, it is what proves the unit left your inventory.
Taking a trade-in: You need the customer's signed title assignment and odometer disclosure, plus a lien payoff quote in writing if the trade is financed. Take the trade in your books at actual cash value, not at the number you allowed on the deal.
Title is not in hand at signing: Title reassignment / power of attorney covers the assignment and mileage disclosure until the title arrives. Track the promise: an unresolved title is the single most common reason a deal unwinds.
Customer pays more than $10,000 in cash: IRS Form 8300 is federal and applies in South Dakota like everywhere else. It covers cash and cash equivalents in one transaction or in related transactions, and it is due within 15 days.

Temporary tags and dealer plates in South Dakota

On each retail sale the dealer issues a temporary 'sold permit' (white), valid no more than 45 days, generated inside the state's 605Drive dealer system and signed by a Dealer Agent to be valid, permits issued outside 605Drive are invalid. Dealer '77' plates go on driven inventory, and blue demonstration/in-transit plates cover demos and transport.

Where South Dakota dealer forms come from

Most dealers search for South Dakota DMV forms, and in South Dakota there is no DMV. The forms come from the SD DOR. Same paperwork, different letterhead, which is worth knowing before you spend an afternoon on the wrong website.

Forms and requirements change. Always pull the current version from the South Dakota Department of Revenue, Motor Vehicle Division, Office of Dealer Licensing. This list was verified 2026-07-17.

Paperwork mistakes that cost dealers money

None of these are exotic. They are the four that turn up again and again in audits and in unwound deals.

Assuming an older car is odometer exempt. The federal rule changed for model year 2011 and newer: those vehicles carry a 20 year disclosure window, not 10. Dealers who learned the old rule skip disclosures they still owe.
A Buyers Guide that is not on the car. The Used Car Rule wants it displayed on the vehicle while it is offered for sale, not produced at signing. It also has to match what you actually agreed to sell, and the copy the buyer takes home governs over the contract if the two disagree.
A title assigned in the wrong hand. Reassignments are limited, the signature has to match the name printed on the title, and a correction fluid fix voids it. That is a duplicate title application and weeks of delay.
Paperwork that lives in a drawer. A form you filed but cannot find is a form you did not file, as far as an auditor is concerned. Store documents against the VIN, not in a filing cabinet by month.

South Dakota dealer forms FAQ

What forms do car dealers need in South Dakota?+

South Dakota dealers use Motor Vehicle/Boat Title & Registration Application (Form 1001), Motor Vehicle Excise Tax (paid via Form 1001), Title reassignment / power of attorney, plus federal forms every dealer needs like the FTC Buyers Guide and the odometer disclosure. Each is listed below with its purpose and official link.

Where do I get official South Dakota dealer forms?+

Download current forms directly from the South Dakota Department of Revenue, Motor Vehicle Division, Office of Dealer Licensing. Third-party copies go out of date, always pull the latest version from the official source linked on this page.

Is it the South Dakota DMV that handles dealer forms?+

Not exactly, and this trips up new dealers. South Dakota does not call it the DMV: the agency is the SD DOR. Searching for "South Dakota DMV forms" is how most dealers look for them, but the official source is the SD DOR.

Do I need an FTC Buyers Guide on every used car in South Dakota?+

Yes. The federal Used Car Rule requires an as-is/warranty Buyers Guide displayed on every used vehicle offered for sale, in South Dakota and every other state.

Does an old car still need an odometer disclosure?+

Usually, yes. The federal exemption changed for model year 2011 and newer vehicles, which now require disclosure for 20 model years instead of 10. A 2011 model still needs a disclosure through 2031, so treat "it's an old car" as a reason to check, not to skip.

How long should I keep South Dakota deal paperwork?+

Keep the complete deal jacket, not just the forms you filed. State record-retention rules run for years and an audit or a customer dispute can land long after the sale. Loturn stores every document against the VIN so the jacket rebuilds itself.
