Overview
Selling or buying a used vehicle in Wyoming? A bill of sale is your proof of the deal — it records who sold what, for how much, and on what date. Wyoming transfers ownership through the signed, notarized title and the MV-300A title application filed with your county clerk, but a bill of sale protects both sides: it locks in the price, the exact handover date, and the fact that the seller is no longer responsible for tickets, tolls, or accidents once the keys change hands.
Wyoming requirements
Is a bill of sale required in Wyoming?
Often yes. When you buy from a private party, most Wyoming counties want a bill of sale — and several require a notarized one — to title the vehicle with the county clerk. Even where it's optional, it's strongly recommended: it proves the price and sale date and shows you're no longer liable for the vehicle.
Does it need to be notarized?
Often, yes. Wyoming requires the seller's signature on the title to be notarized, and the buyer's MV-300A title application must be signed before a notary too. Many counties also ask for a notarized bill of sale on a private sale — check with your county clerk, since requirements vary slightly by county.
Title transfer deadline
After a private-party purchase you may drive on the notarized title or bill of sale for 45 days while you title the vehicle with the county clerk. Sales or use tax is due within 65 days of the purchase date — miss it and Wyoming adds a $25 penalty plus 1% interest per month, rising to the greater of $25 or 10% of the tax.
Motor vehicle sales tax
Wyoming charges sales or use tax on the purchase price at the rate of the buyer's county of residence — roughly 4% to 6% depending on the county. The county treasurer collects it before your first registration, so an accurate sale price on your bill of sale matters.
Odometer disclosure
Federal law requires the odometer reading at the time of sale for vehicles under 20 model years old. Record it on both the bill of sale and the title.

Wyoming bill of sale by vehicle type
The same Wyomingbuilder works for more than cars — pick your vehicle and the form adapts: the right ID number (a VIN, a boat's HIN, or a serial number) and an odometer reading only where one applies.
- Car bill of sale
- Truck bill of sale
- SUV bill of sale
- Van bill of sale
- Motorcycle bill of sale
- ATV bill of sale
- RV bill of sale
- Camper bill of sale
- Trailer bill of sale
- Boat bill of sale
- Jet Ski bill of sale
- Snowmobile bill of sale
- Golf Cart bill of sale
- Tractor bill of sale
A few differ: boats and jet skis use a Hull ID Number (HIN) instead of a VIN and have no odometer; trailers, campers, snowmobiles, golf carts, and tractors have no odometer either; and boats, ATVs, and snowmobiles often register with a different agency (such as a wildlife, boating, or parks department) rather than your county clerk's office (title) and county treasurer's office (registration and tax). Confirm the details with your county clerk's office (title) and county treasurer's office (registration and tax).
Wyoming bill of sale FAQ
Does a Wyoming motor vehicle bill of sale need to be notarized?
Often, yes. Many Wyoming counties require a notarized bill of sale on a private-party sale, and the seller's signature on the title must be notarized either way. Requirements vary slightly by county, so confirm with your county clerk — notarizing is easy and avoids a return trip.
Do I need a bill of sale to sell a car in Wyoming?
Usually, yes. Most counties want a bill of sale to title a privately bought vehicle, and several require it notarized. Beyond the county requirement, it proves the price, the sale date, and that you're no longer responsible for the vehicle after the sale.
Where do I transfer the title in Wyoming?
At your county clerk's office, which issues Wyoming titles. The buyer brings the signed and notarized title, a completed MV-300A title application, and a bill of sale; you then register and pay sales tax at the county treasurer's office.
How long do I have to transfer the title in Wyoming?
After a private purchase you can drive on the notarized title or bill of sale for 45 days while titling with the county clerk. Sales or use tax must be paid within 65 days of the purchase, or Wyoming adds a penalty plus monthly interest — so don't wait.
How much is sales tax on a used car in Wyoming?
It varies by county — generally about 4% to 6% — and is charged at the rate of your county of residence on the purchase price. The county treasurer collects it before your first registration, which is why an accurate sale price on your bill of sale matters.
Do both the buyer and seller need to sign?
Yes. Both parties should sign and date the bill of sale, and each keeps a copy. If there are two buyers or two sellers, every party signs.
Is a handwritten bill of sale valid in Wyoming?
Yes — Wyoming doesn't mandate a specific statewide form, so a handwritten bill of sale is valid as long as it has the key details (and any required notarization). A complete, typed document like this one is simply cleaner and far less likely to be questioned at the county clerk's office.
