Mississippi treats horses as livestock, not vehicles, so there is no state title or registration. Ownership rides on three documents: a written bill of sale (recording price, identification, and transfer date), a current negative Coggins test, and — for registered horses — a transfer recorded with the relevant breed association. Mississippi's Board of Animal Health enforces the Coggins requirement and equine movement rules; a horse moving without papers can be quarantined or refused entry to events. The bill of sale is also the buyer's primary tool against post-sale disputes over soundness and disclosure.
Unlike motor vehicles, horses aren't titled by the DMV — making a written bill of sale your primary legal proof of ownership transfer. Our guide explains what a bill of sale must include to be legally binding and enforceable. Read: What Is a Bill of Sale? →
Mississippi Horse Bill of Sale — What You Need to Know
Mississippi Board of Animal Health (livestock identification)
Primary ID Field
Registration Number
Sales Tax
Exempt
Title Required
No
Mississippi does not title or register horses. Ownership is established by a written bill of sale plus, for registered horses, a transfer of registration with the breed association (AQHA, Jockey Club, APHA, etc.). For grade horses, the bill of sale alone is the primary ownership document.
Inspection
Required
Sales Tax Details
Live horses sold for breeding, racing, or agricultural use are generally exempt from Mississippi sales tax under the agricultural-products exemption. Horses sold strictly for pleasure/recreational use can be taxable at 7% — confirm with your county tax collector or MS DOR if value is significant.
Exemption: Horses qualifying as agricultural livestock (breeding stock, working animals, racing) are exempt from Mississippi sales tax. The buyer should retain documentation of intended use.
Inspection Requirements
A negative Coggins test (EIA) within the past 12 months is required for any horse that is sold, transported across county or state lines, or shown in Mississippi. Out-of-state horses also need a Certificate of Veterinary Inspection (health certificate) within 30 days. Mississippi has no statewide horse brand inspection program.
Registration
Registration for this vehicle type is handled by Breed registry (AQHA, Jockey Club, APHA, etc.) — not a state agency — not the same agency that handles cars in Mississippi. Plan for separate filings.
Mississippi Horse Sale — Step-by-Step Checklist
Record the horse's registered name, barn name, breed, color, markings, age/foaling date, sex, and microchip number
List the breed-registry number (AQHA, Jockey Club, APHA, etc.) if registered
Attach a current negative Coggins test (within the past 12 months) — Mississippi law requires it for sale and transport
Disclose known vices, lameness, prior surgeries, and medications (a "sound to seller's knowledge" clause is common)
Specify whether the sale is "as-is" or includes a vet-check contingency and trial period
Both parties sign and date; have the seller sign the breed registry transfer form on the same day
For high-value horses, have the bill of sale notarized to prevent later identity disputes
Common Pitfalls
Buying a horse without a current negative Coggins — the buyer cannot legally transport it in Mississippi
Skipping a pre-purchase vet exam — soundness issues found later are usually the buyer's problem in private sales
Failing to file the breed-association transfer paperwork — registration stays in the seller's name and can't be used for showing or breeding
Vague identification ("brown gelding, about 12") that cannot uniquely identify the animal in a dispute
No written disclosure of medications (especially long-acting joint injections that mask lameness during a trial ride)
Verbal-only "trial period" agreements — get all return conditions in writing
Pro Tip
Mississippi keeps horse sales informal at the state level — no titles, no registration — but Coggins enforcement is real, and breed-association paperwork matters for resale value. A specific bill of sale plus signed registry transfer plus current Coggins is the three-document package every Mississippi horse buyer should walk away with.
Mississippi Horse Bill of Sale — FAQs
Does Mississippi require a Coggins test to sell a horse?
Yes. Mississippi Board of Animal Health rules require a current negative Coggins test (Equine Infectious Anemia, dated within the past 12 months) for any horse that is sold, transported on public roads, exhibited, or assembled with other horses. The seller should provide the original Coggins paperwork to the buyer at the time of sale, and that document — along with the bill of sale — should travel with the horse on the trailer ride home. Selling or moving a horse without current Coggins exposes both parties to quarantine orders, fines, and potential refusal of entry at any event or boarding facility. Budget $35-$60 for the test if you need a fresh one before the sale.
How do I transfer ownership of a registered horse in Mississippi?
For a registered horse (Quarter Horse, Thoroughbred, Paint, Arabian, etc.), Mississippi has no role — the transfer happens with the breed association, not the state. The seller signs the registration certificate over (or completes the association's transfer form) and submits it with the appropriate fee. Until the registry processes the transfer, the previous owner remains the "owner of record" for breeding rights, prize money, and showing eligibility. Best practice: have the seller hand you the signed transfer form at the same time as the bill of sale, and submit it to the registry yourself within a week. Pair the registry transfer with a Mississippi bill of sale that documents price, date, and the horse's identification — that bill of sale, not the registration, is what proves transfer of legal ownership in a Mississippi court.
Do I owe sales tax on a horse purchase in Mississippi?
It depends on use. Mississippi exempts livestock — including horses — sold for breeding, agricultural, or racing use under the agricultural-products exemption. A horse purchased strictly as a recreational riding mount can technically be taxable at the 7% general rate. In practice, most private horse sales in Mississippi are not collected on by the state because no licensed reseller is involved, but if you buy a high-value show horse or sport horse from a dealer or barn operating as a business, expect tax on the bill. Keep your bill of sale on file regardless — if MS DOR ever inquires, the bill of sale and a statement of agricultural use is your documentation.
Can I sell a horse "as-is" in Mississippi?
Yes. Private horse sales between non-dealer parties are governed by general Mississippi contract law, and "as-is" clauses are enforceable when clearly written. The bill of sale should state explicitly that the horse is sold "as-is, where-is, with no warranty of soundness, suitability for any particular use, temperament, or future health." That said, "as-is" does not protect a seller who actively misrepresents the horse — claiming a horse is "100% sound" when the seller knows it has navicular disease is fraud regardless of the bill of sale. Buyers should always insist on a pre-purchase exam by an independent vet, including flexion tests and (for higher-value horses) radiographs of the front feet and hocks. The cost is small compared to colic surgery or a long-term lameness problem.
