Free Hawaii Trailer Bill of Sale
Hawaii trailer sales run through the same four-county Department of Finance system as cars and motorcycles — with the added complexity of two separate thresholds: registration is required for trailers 750 lbs GVWR and up, while actual title is required only for trailers 2,000 lbs GVWR and over. Hawaii's private-sale General Excise Tax exemption applies to trailers just as it does to all other vehicles, and the county-based system means the buyer must use the office for their specific island.

Hawaii Trailer Bill of Sale — What You Need to Know
Sales Tax Details
No General Excise Tax on private-party trailer sales in Hawaii. The GET at 4% applies only to dealer/business transactions. Private individuals transferring a trailer pay no state tax.
Inspection Requirements
Hawaii does not require a safety inspection for trailer registration or transfer. Lighting and brake equipment requirements apply during road operation.
Hawaii Trailer Sale — Step-by-Step Checklist
- Determine the trailer's GVWR: under 750 lbs (no registration or title needed), 750–1,999 lbs (registration required, no title), or 2,000 lbs and over (both registration and title required).
- Locate the VIN on the tongue or main frame rail — older trailers may have a serial number rather than a standard VIN.
- Draft a bill of sale with VIN or serial number, trailer type (utility/cargo/boat/car hauler), GVWR, length, year, make, sale price, date, and both parties' full names and addresses.
- For titled trailers (2,000 lbs GVWR+): seller signs the Hawaii title over to the buyer.
- For registration-only trailers (750–1,999 lbs): seller provides bill of sale and current registration card.
- Seller removes Hawaii license plate — plates stay with the seller in Hawaii.
- Buyer visits the appropriate county motor vehicle office for their island within 30 days: Honolulu (Oahu), Maui County, Hawaii County (Big Island), or Kauai County.
- Buyer pays county registration and title fees (for applicable weight class) — no General Excise Tax on private sales.
Common Pitfalls
- Misapplying the two-tier threshold: Hawaii has a lower registration threshold (750 lbs GVWR) than most states and a separate title threshold (2,000 lbs GVWR). Sellers of trailers in the 750–1,999 lb range need to provide the registration card, not a title — but a registration transfer still needs to be processed at the county office.
- Wrong county office: Hawaii's county-based system means a buyer on Oahu cannot process a trailer transfer at a Big Island county office. Confirm the buyer's island before scheduling the paperwork handoff.
- Boat trailer sold with vessel: if a boat trailer is sold with a boat, the boat goes to DOBOR and the trailer goes to the county DMV — two separate agencies and two separate transfer processes.
- Homemade or altered trailers: Hawaii requires a VIN assignment from the county DMV for homemade trailers before a title can be issued. Buyers of homemade trailers should confirm with their county office whether a VIN inspection is needed.
Pro Tip
Hawaii trailer sales require attention to two GVWR thresholds and the county-based system. Confirm the trailer's GVWR before deciding whether a title transfer or just a registration transfer is needed, use the correct island's county office, and keep the bill of sale on hand — it's the primary transfer document for sub-2,000 lb trailers where no title exists. No sales tax on either side keeps the transaction clean.
