Free South Dakota Horse Bill of Sale
Selling a horse in South Dakota is more regulated than most people expect because of the state's mandatory brand inspection law — one of only a handful of states that still enforces this. Any change of ownership in the brand inspection area (most of the western half of SD) or any movement of a horse out of that area triggers a required visit from a SD Brand Board inspector before the sale can lawfully complete. Pair the brand inspection certificate with a written bill of sale, current negative Coggins, and a Certificate of Veterinary Inspection if the horse is crossing state lines.

South Dakota Horse Bill of Sale — What You Need to Know
Sales Tax Details
South Dakota does not impose the 4% Motor Vehicle Excise Tax on horses — they aren't titled vehicles. The state's 4.2% general sales tax technically applies to retail sales of tangible personal property, but isolated/casual private-party sales between non-dealers are generally not taxable. Horse sales conducted by licensed dealers, auction houses, and breeders operating as a business will collect 4.2% state sales tax plus any municipal sales tax (typically 1-2% on top). Always get a written tax statement at auction.
Inspection Requirements
South Dakota has MANDATORY brand inspection by the SD Brand Board for any change of ownership of horses within the brand inspection area (most of western SD) and for any movement of horses out of the brand inspection area — including selling to a buyer in a non-brand-inspection county or shipping out of state. This is rare among US states; most states have no brand inspection at all. The seller must call a brand inspector before delivery, the inspector verifies the horse against the seller's ownership, examines existing brands, and issues a Brand Inspection Certificate. Fees are typically $5-10 per head plus mileage. Beyond brand inspection, a current negative Coggins (EIA) test within 12 months is required for sale and for any interstate movement, and a Certificate of Veterinary Inspection (CVI/health certificate) within 30 days is required to cross state lines.
Registration
Registration for this vehicle type is handled by SD Brand Board (brand inspection) and breed registry (e.g., AQHA, APHA, Jockey Club) — not the same agency that handles cars in South Dakota. Plan for separate filings.
South Dakota Horse Sale — Step-by-Step Checklist
- Buyer and seller full legal names, mailing addresses, and phone numbers
- Date of sale and physical location where the horse is delivered
- Horse's registered name, barn name, breed, sex, color, age, height, and markings
- Brands, scars, tattoos, and microchip number — required to match the SD Brand Inspection Certificate
- Breed registration number and registry (AQHA, APHA, Jockey Club, etc.) if applicable
- Coggins (EIA) test date, accession number, and result — must be negative and within 12 months
- SD Brand Inspection Certificate number — required for ownership change in brand inspection area
- Sale price and any deposit received
- "As-is" language with explicit disclaimers about soundness, behavior, and breeding warranties
- Both signatures dated the day of sale; notarization recommended for sales over $5,000
Common Pitfalls
- Skipping the SD brand inspection on a horse moving out of the brand inspection area. The state can fine you, refuse to recognize the sale, and impound the horse at the destination. Brand inspection is not optional in most of western SD — it's a $5-10 piece of paper that protects the entire transaction.
- Selling without a current negative Coggins. SD requires a negative EIA test within 12 months, and almost every interstate buyer will refuse a horse without one. If the test is more than 12 months old, get a fresh draw before the sale.
- Forgetting the Certificate of Veterinary Inspection (CVI) for interstate movement. SD-to-anywhere shipments require a CVI within 30 days from a USDA-accredited vet. Without it the buyer can be turned around at a state line or quarantined.
- Verbal warranties that contradict written "as-is" language. SD courts have held that strong verbal claims about soundness or training can override written disclaimers. If you say "she's 100% sound and never bucked" and she does both, expect a lawsuit.
- Not transferring breed registry papers. AQHA, APHA, Jockey Club, etc. all have their own transfer fees and forms. The SD bill of sale is not a substitute — papers stay with the registry until properly assigned.
Pro Tip
Horse sales in South Dakota carry an extra step most states don't — the mandatory brand inspection — but the system actually protects buyers and sellers by creating a clean ownership chain. Get the brand inspection scheduled, pull a current Coggins, sign two copies of the bill of sale, transfer the breed registry papers, and write everything down. If the horse is leaving the state, add a CVI from a USDA-accredited vet.
