Government Auction Fees, Deposits and Premiums
Government auction fees explained: buyer premiums, deposits, sales tax, title costs, storage charges and default penalties, with ranges by sale type.

Quick answer
Government auction fees come in four layers: a buyer premium added to the hammer price (none at many agency-run sales, a percentage on contractor platforms), a deposit required to register or bid (flat or a percentage, refundable to losers and applied or forfeited for winners), taxes and transfer costs charged at the sale or at registration, and post-sale charges such as storage, late fees and default penalties. The notice states every one of them, and your maximum bid should be set after adding them up.
The four layers of cost
New buyers focus on the hammer price because that is the number that moves during the sale. Experienced buyers work backward from the all-in cost. The layers are consistent across sale types even though the amounts are not: a premium or fee added by the seller or platform, a deposit that gates participation, the taxes and transfer costs that apply to any purchase, and the charges that appear after the sale if you are slow to pay or collect. This guide takes each layer in turn and ends with a worksheet you can use for any lot. For the overall process, see how government auctions work.
Deposits
A deposit proves you can perform. For online surplus goods it is usually a card on file rather than cash. For vehicles and equipment some sellers require a deposit per lot or per sale. For real estate the deposit is real money: a flat registration deposit, a percentage of your expected bids, or a percentage of the winning bid due at the fall of the hammer in certified funds. The notice states whether the deposit is refunded to losing bidders (it usually is), applied to the winner’s price (it usually is), and forfeited on default (it always is).
| Sale type | Deposit pattern | When due | Refund to non-winners |
|---|---|---|---|
| Online surplus goods | Card on file; occasionally a small refundable deposit | At registration | Automatic |
| Fleet and seized vehicles | Flat deposit per bidder or per lot at some sales | At registration or before bidding | Within days after the sale |
| Tax deed or tax lien sale | Flat $200–$1,000+ or 5–10% of anticipated bids | Before the sale opens | After the sale closes |
| Sheriff or judicial sale | Commonly 10–20% of the winning bid in certified funds | At the sale | Not applicable; only the winner pays |
| Sealed-bid land sale | Fixed amount or percentage submitted with the bid | With the bid | After bid opening |
| Bankruptcy 363 sale | Percentage of the purchase price with the qualified bid | By the bid deadline | After the sale hearing or closing |
Taxes, title and transfer costs
Sales tax or use tax applies to most goods and vehicles unless you hold a valid resale certificate or exemption. Some platforms collect it at checkout; others leave it to your state at registration. Vehicles add title, registration, plate, and inspection fees. Real estate adds recording fees, any transfer or documentary tax, deed preparation, and in tax-sale states the cost of curing title before an insurer will issue a policy.
- Goods: sales or use tax at the local rate; sometimes on price plus premium.
- Vehicles: sales tax, title fee, registration, plates, inspection or emissions test.
- Real estate: recording fee, transfer tax, deed preparation, title search, and possibly a quiet-title action.
- Business buyers: keep a resale certificate on file with each platform to avoid tax on inventory.
Post-sale charges: storage, late fees and defaults
The charges that surprise buyers appear after the win. Surplus warehouses commonly give a pickup window of a week or two and then charge daily storage or treat the item as abandoned with no refund. Vehicle yards charge storage after the removal deadline. Real-estate sellers rarely charge storage, but a missed payment deadline is a default: the deposit is forfeited, the property is re-offered, the defaulting bidder can be liable for any shortfall on resale, and many counties bar defaulters from future sales.
| Sale type | Common consequence |
|---|---|
| Online surplus goods | Card charged or deposit kept; item re-listed; account suspended |
| Fleet or seized vehicle | Deposit forfeited; vehicle re-listed; possible ban |
| Tax deed or lien sale | Deposit forfeited; parcel re-offered; bidder barred, sometimes for years |
| Sheriff or court sale | Deposit forfeited; resale at bidder’s risk for the shortfall; possible contempt or civil liability |
| Bankruptcy sale | Deposit forfeited; back-up bidder may close; damages under the agreement |
An all-in bid worksheet
Work through the lines before the sale opens and write the resulting maximum where you can see it while bidding.
- Estimate what the asset is worth to you: resale value, use value, or the return on a lien.
- Subtract the buyer premium as a percentage of your intended bid.
- Subtract sales or use tax, or transfer and recording costs for real estate.
- Subtract transport, removal labor, and equipment, or a survey and title work for land.
- Subtract immediate repairs, curative title work, and any conditions the seller imposes.
- Subtract a risk reserve for what you could not inspect (commonly 5–10%, more for real estate sold sight unseen).
- The remainder is your maximum bid. If it is below the minimum bid, pass.
Example: a surplus pickup on a commercial platform
Retail value to you: $12,000. Platform premium: 12%. Sales tax: 7% on price plus premium. Transport: $400. Day-one service: $900. Reserve: $600. Working backward, a bid of about $8,500 lands at roughly $11,900 all-in, so $8,500 is the ceiling, not $10,000. Compare live vehicle listings with that discipline and the bargains sort themselves out.
Example: a tax deed parcel
Value after cleanup: $60,000. Quiet-title and legal: $4,000. Recording and transfer: $500. Debris removal and securing: $3,000. Holding costs for a year: $2,500. Reserve for surviving liens and surprises: $6,000. The maximum bid is about $44,000, and the deposit and certified-funds deadline in the notice decide whether you can perform. The tax deed guide covers what else can survive the sale, and the real estate directory shows current sales by state, such as Florida and Pennsylvania.
Reading the fee section of a notice
Every official notice has a terms section. Find these phrases and record the numbers.
- “Buyer’s premium” or “administrative fee”: the percentage, any cap, and whether tax applies to it.
- “Deposit” or “registration fee”: amount, form of payment, refund timing, and forfeiture conditions.
- “Payment in full”: deadline, accepted methods, and the time zone.
- “Removal” or “possession”: deadline, appointment rules, storage charges, and abandonment terms.
- “Default”: what the seller may do, including resale at your risk and bans.
- “As is, where is”: the warranty disclaimer that makes inspection your responsibility.
Frequently asked questions
What is a buyer premium at a government auction?
A percentage of the winning bid added to your invoice to pay the auctioneer or platform. Many agency-run sales charge none; contractor and commercial platforms commonly add a percentage, sometimes capped. The notice states the exact rate.
Do I get my deposit back if I lose?
Usually yes, within days after the sale, by the method the seller specifies. Winners have the deposit applied to the price; defaulters forfeit it.
Is sales tax charged at government auctions?
Commonly yes on goods and vehicles unless you hold a valid resale certificate or exemption. Some platforms collect it at checkout; others leave it to your state at registration. Real estate is subject to recording and transfer costs instead.
How much should I budget above the hammer price?
For goods and vehicles, a rough rule is 10–20% for premium, tax, and transport, plus day-one service. For real estate, add recording, title work, holding costs, and a reserve for surviving liens. Build the number from the notice, not from a rule of thumb.
What happens if I win and do not pay?
You default: the deposit or card charge is kept, the asset is re-offered, you may be liable for a resale shortfall, and many sellers bar you from future sales. Court sales can carry additional legal consequences.
Are fees negotiable after the sale?
No. Public sellers apply the published terms to every bidder equally and cannot waive fees or deadlines for one buyer. Everything must be priced before you bid.
