Frequently Asked Questions

Common questions about auction fees and how to budget for them.

Why do auction fees vary so much between IAAI and Copart?

Both IAAI and Copart use tiered buyer fee structures, but the tiers, minimums, and add-on fees differ. Copart often has higher internet and gate fees, while IAAI may have different environmental charges depending on state regulations. Always review the specific fee schedule for the location where you're bidding.

Are Manheim and ADESA really cheaper than salvage auctions?

Generally yes. Wholesale dealer auctions like Manheim and ADESA charge flat buyer fees ($300–$500) rather than percentages, making them more predictable on higher-priced vehicles. However, you need a dealer license to participate, and the inventory is clean-title wholesale rather than salvage.

What's the biggest hidden fee dealers forget?

Storage fees. Both IAAI and Copart start charging daily storage if you don't pick up the vehicle within 3–5 business days. At $20–$50 per day, this can erase your margin fast. Factor transport timing into your bid calculation.

Do I pay sales tax on the bid amount or the total with fees?

It depends on the state. Most states tax the total purchase price including buyer fees but excluding transport. Some states tax only the bid amount. This calculator uses the bid amount as the tax base for simplicity—adjust the tax rate to match your local rules.

Can I negotiate auction fees?

Not the standard fees, but volume matters. High-volume dealers often get preferred buyer fee tiers, waived internet fees, or faster title processing. If you're buying 10+ cars per month, contact your auction representative to discuss a commercial account.
