Mississippi Vehicle Bill of Sale Laws — 2026 Legal Requirements

Mississippi bill of sale: what state law requires

Mississippi treats a private vehicle bill of sale as legally binding once both parties sign. The document serves three functions under state law: it transfers ownership, establishes the agreed price for sales tax purposes, and creates evidence that the seller is no longer responsible for the vehicle after the sale date. Mississippi does not publish a mandatory official form, but the bill of sale must contain specific required fields to be accepted by the Mississippi DMV.

Required disclosures and fields

Every bill of sale used for a Mississippi private vehicle transfer must include the buyer's and seller's full legal names, addresses, and signatures, the vehicle identification number (VIN), year, make, and model, the odometer reading at the time of sale, the agreed sale price (or notation of gift if no money changed hands), and the date of the transaction. Mississippi accepts a typed or handwritten document so long as all required fields are present and legible.

• Reduced 5% sales tax rate for vehicle purchases
• Title transfer at county tax collector office
• Seller must provide title signed and notarized

Notarization rules in Mississippi

Mississippi does not require the bill of sale or the title to be notarized for a private vehicle sale. Both parties simply sign and retain copies. Notarization is optional but recommended for vehicles over $5,000 to add fraud-protection evidence.

Title transfer deadlines

Under Mississippi law, the buyer must complete the title transfer at the Mississippi DMV within 7 days of the sale date. Missing this deadline results in late title fees, which compound over time. The deadline begins on the sale date documented in the bill of sale, which is one of the reasons the document is required. The state title fee is $9. Current procedures are published at the Mississippi DMV.

Odometer disclosure under federal and Mississippi law

Federal law under 49 CFR Part 580 (the Truth in Mileage Act) requires the seller to certify the odometer reading in writing at the time of sale for any vehicle under 10 model years old and under 16,000 pounds GVWR. In Mississippi this disclosure is typically made directly on the title in the designated odometer field; if the title lacks the field, the bill of sale must serve as the disclosure document. Falsifying an odometer disclosure is a federal crime under 49 U.S.C. § 32709 with civil penalties of up to three times actual damages or $10,000 per violation, plus state-level consumer-protection penalties.

Sales tax obligations

Mississippi applies the following sales tax to private vehicle sales: 5% sales tax on vehicle purchases (reduced rate). The seller is not responsible for collecting or remitting sales tax in a private-party sale — that is the buyer's obligation at the DMV. However, the bill of sale must accurately state the sale price; the DMV uses this figure (or the state's published fair-market value, whichever is higher) to compute the tax.

Penalties for non-compliance

Failing to comply with Mississippi bill of sale and title transfer law exposes both parties to risk. Sellers who do not file a release of liability remain legally responsible for the vehicle after sale and can be held accountable for the buyer's parking tickets, toll violations, and even accidents. Buyers who do not transfer the title within the statutory deadline incur late fees and, in some cases, criminal penalties for unregistered vehicle operation. Both parties are also at risk if the bill of sale contains an inaccurate sale price intended to reduce sales tax — this constitutes tax fraud under Mississippi and federal law.

Buyer and seller rights

Under Mississippi law, both buyer and seller have specific rights that the bill of sale documents. The seller has the right to be released from liability once the title is transferred — the bill of sale, along with the release of liability filing, is the seller's primary evidence of transfer. The buyer has the right to a clean title and an accurate odometer reading; if either is misrepresented, the buyer may pursue civil action under Mississippi consumer-protection statutes and federal Truth in Mileage Act provisions. Both parties have the right to retain signed copies of the bill of sale for their records.
