Free Wyoming Used Car Bill of Sale
Buying a used car from a private seller in Wyoming is a straightforward transaction: a bill of sale only in some situations, no mandatory inspection, and the buyer handles the tax payment directly with the county treasurer. The biggest risk in Wyoming used-car sales is the seller's lien — if the title shows a lienholder, that release must be in hand before money changes hands.

Wyoming Used Car Bill of Sale — What You Need to Know
Sales Tax Details
4% state sales tax plus county local option tax (typically 1%–2%). Total rate: 5%–6%. Teton County is 6%. Paid by the buyer to the county treasurer before first registration — not collected by the seller.
Exemption: No exemption for casual used-car sales between private parties.
Wyoming Used Car Sale — Step-by-Step Checklist
- Run a VIN check (NMVTIS or CARFAX) to confirm title status, odometer history, and any prior salvage or flood designations.
- Verify the seller's identity matches the name on the title; if the title is in a deceased owner's name, an estate executor must sign.
- Obtain a signed lien release if the title shows any lienholder — call the lender directly if the seller claims it was paid off.
- Complete a written bill of sale with VIN, year, make, model, odometer reading, agreed sale price, date, and both parties' full names, addresses, and signatures.
- Seller endorses the title on the back with their signature (made before a notarial officer), the buyer's name, odometer reading, and sale date.
- Buyer takes the signed title, lien release, and a bill of sale if the clerk asks for one to the county clerk's office in the buyer's county of residence within 45 days.
- Pay state and local sales tax (4% + local) and registration fees to the county treasurer; receive the new Wyoming title from the county clerk.
Common Pitfalls
- Paying the seller 'to cover the tax': Wyoming places the sales tax obligation on the buyer, collected by the county treasurer. Paying the seller extra does not satisfy this obligation.
- Accepting a title with an unsatisfied lien: the county clerk will refuse the transfer without a lien release, leaving the buyer stuck until the seller locates the lender.
- Not confirming the seller is the title holder: if the title was never transferred to the seller after they bought the car, the county clerk may require proof of the full chain of ownership.
- Skipping the VIN check on high-mileage trucks: Wyoming's rural market has a significant volume of work trucks with rolled-back odometers — NMVTIS history is cheap insurance.
Pro Tip
Protect yourself in a Wyoming used-car purchase by never releasing payment without a clean, properly endorsed title and a lien release if one is needed. Keep your bill of sale permanently — it is your primary proof of the purchase price if a tax dispute arises later.
