Free Utah Trailer Bill of Sale
Utah's trailer threshold is startlingly low: 750 pounds. Any trailer over that weight operated in Utah — including travel and tent trailers — must be titled AND registered through the DMV, which pulls in trailers that half the neighboring states would wave through unregistered. The transfer follows Utah's standard machinery: the versatile TC-843 bill of sale (one form covers vehicles, boats, and trailers), a 60-day window, and the 4.85% state tax base plus local rates. Under 750 pounds, the little garden trailer escapes the system and rides on its bill of sale.

Utah Trailer Bill of Sale — What You Need to Know
Sales Tax Details
Same state + local tax rates apply to trailers.
Utah Trailer Sale — Step-by-Step Checklist
- Weigh the question first: over 750 pounds means Utah title AND registration; under it, the trailer transfers on the bill of sale.
- Verify the VIN or serial plate on the tongue against the Utah title.
- Complete Form TC-843 — Utah's combined bill of sale for vehicles, boats, and trailers — with VIN/serial, type, weight, price, date, and both signatures.
- Seller signs the title over on 750-plus-pound trailers.
- Buyer files at the Utah DMV within 60 days.
- Buyer pays the 4.85% state base plus local sales taxes and the title/registration fees.
- Travel or tent trailer? The 750-lb rule almost certainly covers it — budget the full title-and-registration path.
Common Pitfalls
- Applying a neighbor's threshold — Utah's 750-pound line catches trailers that Idaho, Wyoming, or Oklahoma would leave bare; assume the paperwork applies here.
- Rushing for an imaginary 45-day deadline or coasting past the real one — Utah's transfer window is 60 days.
- Budgeting only the 4.85% — local rates stack by address, as with every Utah vehicle purchase.
- Skipping the bill of sale on a sub-750-lb trailer — with no title in the system, that document is its entire ownership history.
Pro Tip
Utah trailers: the 750-pound line pulls almost everything into title-and-registration, TC-843 documents it, and the buyer has 60 days at 4.85% plus local.
