Free Wyoming Vehicle Bill of Sale
Wyoming keeps vehicle sales simple: there is no state-issued bill of sale form, any written document accepted by the county clerk will do, and the 4% base sales tax is among the lowest in the nation. Because Wyoming uses a fully decentralized titling system — the county clerk, not a state DMV office, handles every transfer — you'll need to know which of the 23 county offices to visit within your 30-day window.

Wyoming Vehicle Bill of Sale — What You Need to Know
Sales Tax Details
4% state sales/use tax plus local option taxes; most counties collect 5%–5.5% total. Teton County (Jackson Hole) reaches 6%. Tax is paid to the county clerk at the time of titling — not to the seller.
Inspection Requirements
Wyoming has no statewide safety inspection requirement for private vehicle sales.
Wyoming Vehicle Sale — Step-by-Step Checklist
- Draft a written bill of sale including VIN, year, make, model, odometer reading, sale price, date, and full names and addresses of both buyer and seller.
- Seller signs the back of the title over to the buyer and completes the odometer disclosure section (required by federal law for vehicles under 20 years old).
- If a lienholder appears on the title, obtain a signed lien release before the sale closes.
- Buyer takes the signed title, bill of sale, and lien release (if applicable) to the county clerk's office in the county where the buyer resides.
- Buyer pays state sales/use tax (4% + local) to the county clerk at the time of titling.
- County clerk issues a new Wyoming title in the buyer's name; buyer receives registration plates or transfers existing ones.
- Both parties retain a copy of the bill of sale for at least five years.
Common Pitfalls
- Missing the 30-day titling window: late fees apply and the buyer risks driving with an unregistered vehicle.
- Assuming the seller owes sales tax: in Wyoming casual sales, the buyer pays the tax to the county clerk — sellers who agree to 'cover tax' in the sale price often miscalculate.
- Forgetting the lien release: a title showing an outstanding lienholder cannot be transferred without a signed release, even if the loan was paid off years ago.
- Odometer disclosure omitted on sub-20-year vehicles: federal law requires disclosure; missing it can void the sale or create liability for the seller.
- Going to the wrong county office: Wyoming titles through the buyer's county of residence, not the county where the sale occurred.
Pro Tip
For the smoothest Wyoming vehicle sale, complete the odometer disclosure on the title at signing, hand the buyer a written bill of sale the same day, and remind them that the clock on their 30-day titling window starts on the sale date shown in the document.
