Free Wyoming Trailer Bill of Sale
A Wyoming trailer transfer walks the same two-desk courthouse route as every Wyoming vehicle: the county CLERK in the buyer's county seat issues the Certificate of Title, and the county TREASURER collects the flat 4% sales tax — a payment that must land within roughly 65 days of the sale before penalties attach. There's no central WYDOT branch to visit, no inspection to schedule, and no local tax variation across the 23 counties. The bill of sale fixes the price and the date; the two county offices do the rest.

Wyoming Trailer Bill of Sale — What You Need to Know
Sales Tax Details
Same 4% flat sales tax on trailers.
Wyoming Trailer Sale — Step-by-Step Checklist
- Verify the VIN or serial plate on the tongue against the Wyoming title.
- Write the bill of sale with VIN/serial, type, weight, sale price, an exact date, and both signatures.
- Seller signs the title over.
- Buyer takes the signed title to the county CLERK at the county seat for the new Certificate of Title.
- Buyer pays the flat 4% sales tax at the county TREASURER within ~65 days of the sale.
- Handle both desks in one courthouse visit — clerk first, treasurer second — and both clocks resolve together.
- No inspection applies to Wyoming trailers.
Common Pitfalls
- Completing only one desk — a titled-but-untaxed (or taxed-but-untitled) trailer is a half-finished Wyoming transfer.
- Missing the ~65-day treasurer clock — the tax penalty runs separately from the title paperwork.
- Hunting for a WYDOT office — private trailer transfers live at the county courthouse.
- Expecting county rate differences — Wyoming's 4% is uniform in all 23 counties.
Pro Tip
Wyoming trailers: clerk for the title, treasurer for the flat 4% within ~65 days — one courthouse, two desks, zero inspections.
