Bought a Trailer at Auction — Now What?
Last reviewed: January 2025
Buying a trailer at auction — whether a government surplus auction, equipment auction, or general vehicle auction — is a great way to find good deals. But auction paperwork is different from private sales, and not all auction houses provide the same documentation. Here's what you typically receive and how to title it.
What Auction Paperwork Is Accepted for Titling
Most state title offices accept the following from auction purchases:
- Auction Receipt / Bill of Sale: An official receipt from the auction house showing the trailer description, VIN, your name as buyer, purchase date, and purchase price. Most licensed auction houses provide this automatically.
- Signed Title from Auction House: If the auction house held the original title, they sign it over to you as the seller. This is the cleanest path — treat it like any other title transfer.
- Auctioneer's Certificate: Some government auctions provide a special certificate in lieu of a title. This is generally accepted at state title offices as equivalent to a signed title.
Government Surplus Auction Trailers
Federal and state government auctions (GSA, state surplus, municipal fleet sales) typically provide a Certificate of Release or similar document. These are widely accepted by title offices nationwide. You'll apply for a new title using this certificate plus your state's standard title application form.
What If the Auction Only Gave You a Receipt?
Some smaller or informal auctions only provide a receipt — no signed title. In this case:
- Contact the auction house and request a proper bill of sale that includes the VIN and both parties' signatures
- Ask them to provide the original title or contact the previous owner to obtain a signed title
- If neither is possible, the bonded title process applies — see our bonded title guide
Ask the auction house what title documentation they provide before you bid. Reputable auction houses will tell you clearly whether they have a title in hand. Bidding on a trailer without a title and then discovering you need to pursue a bonded title adds cost and weeks to the process.
Do I pay sales tax on an auction trailer purchase?
Yes — most states collect sales or use tax when you title a trailer, regardless of how it was purchased. The tax is calculated on the purchase price shown on your auction receipt. Some states exempt government surplus sales from use tax — check with your state's title office.
Can I use an online auction receipt (GovPlanet, IronPlanet, etc.) for titling?
Yes, if the receipt includes the required information: VIN, buyer's name, seller's name, purchase date, and price. Major online equipment auction platforms typically provide proper documentation. Contact their customer service team if you need additional paperwork formatted to your state's requirements.
