This is the form people reach for after a sale, and reading it is how you find out that South Dakota does not work the way they expect. Selling a car does not produce a registration refund here. SDCL 32-5-2.7 gives the transferor a credit for the unexpired months, and only at the time the plates are attached to another vehicle - and it adds that no refund may be issued if the plate is detached and not reattached. Form 1600 covers three other things: a commercial licence being surrendered, a non-commercial registration that was renewed in error, and an excise tax paid on the wrong basis. The last of those is the one a private sale can actually trigger.
Written against Form 1600 (no revision printed), issued under South Dakota Department of Revenue, Motor Vehicle Division, non-commercial refunds under SDCL 32-5-24. The one line on this form that a private seller can genuinely use is the excise tax refund for a missing or incomplete bill of sale. If your buyer went to the counter without one and was taxed 4% of a dealers' guide value rather than 4% of what they paid, this is the route back - but it needs the original title surrendered, a $10 title correction fee and the bill of sale that should have been there. Which is the argument for writing one properly on the day: recovering the overpayment costs your buyer a trip, a fee and the certificate they have just waited for.
Two documents, and they are not the same thing. Take the blank Form 1600 from the sddor.seamlessdocs.com copy so you get the revision that is current today, then print our Form 1600 guide and keep it beside you while you fill theirs in.
This is the actual Form 1600, rendered from the PDF the South Dakota Department of Revenue, Motor Vehicle Division publishes and completed end to end: letterhead, every field, and the blocks at the foot.
Name and address of the vehicle owner. The form notes that refunds are paid directly to the vehicle owner.
Watch out: It has to be the owner. A refund on a car already sold cannot be redirected to the buyer, which is one more reason the timing of these matters.
Year, make, model, transaction number, title number, VIN, plate number, date of registration and county.
Watch out: The transaction number comes off the receipt the county gave you when the registration was paid. Without it the county is searching by hand.
Commercial, non-commercial, or the 4% excise tax refund - one tick, with the certification printed beside it.
Watch out: None of the three is a refund for selling the car. A South Dakota sale produces a credit against the next vehicle's registration and only when the plates are physically reattached.
Either the bill of sale was not available or incomplete at the time of application, or the trade-in or purchase was indicated incorrectly by the dealership.
Watch out: The first reason is the one that follows a private sale, and it needs the bill of sale that was missing, the original title and a $10 title correction fee.
One owner's signature and date. The plates, registration and unused decals go in with the form on the registration routes.
Watch out: Ninety days on the non-commercial route, and the stickers have to come back unused and still attached to the registration card.

Every line here was read off Form 1600 (no revision printed) itself — the PDF is here — and off the South Dakota Department of Revenue, Motor Vehicle Division pages. This is plain-language help with a form, not legal advice, and where our wording and the agency's differ, theirs governs.
