IAAI Car Total Cost in Idaho (2026)

IAAI in Idaho: four hammer prices

Idaho tax is applied to the hammer price only. No storage days are assumed.

What the IAAI side of a Idaho bill is made of

IAAI's side of the Idaho bill is a tiered buyer fee, an internet bid fee, a $105 service fee (Copart's equivalent is a gate fee), a $15 environmental fee and a $20 title fee: $884 at a $7,500 hammer.

These Idaho totals use IAAI's Standard (non-Public) registration schedule. IAAI has no Premier tier like Copart's; Public Auto Auction registration is the broad-access option, and some licensed dealers get discounted dealer fees. Full tier tables are in the IAAI fee calculator.

Idaho tax and title on a IAAI buy

Idaho state rate is 6%. Some resort cities add up to 3% local. Trade-in deductible.

• Rate applied to a IAAI hammer: 6% state rate.
• Local add-on: up to 3.00% more in some Idaho jurisdictions, or $45 on a $1,500 IAAI bid, $120 on a $4,000 IAAI bid, $225 on a $7,500 IAAI bid, $360 on a $12,000 IAAI bid.

Buying IAAI cars in Idaho with a dealer license

Idaho dealer licenses come from Idaho Transportation Department, Vehicle Services / Dealer Services. Bond: $20,000 (Retail (used) dealer); $40,000 (Wholesale-only dealer). The state's own wording on when you count as a dealer: "sells five or more vehicles/vessels (that are required to be titled) per calendar year"

Idaho issues a separate wholesale-only dealer license, which carries a higher ($40,000) bond than a retail dealer and is exempt from the ICAR fund fee.

A dealer must operate from an enclosed commercial structure built to code, in an appropriately zoned area, with a permanently affixed exterior sign, a defined office, and a display area large enough to display five or more vehicles/vessels of the type the dealer is licensed to sell.

State licensing fees in Idaho: Initial Dealer's License $190; ICAR Fund fee (paid by retail dealers in addition to bond) $300.

Every licensing fact with its source is on the Idaho dealer license guide.

IAAI or Copart in Idaho

Idaho tax and title are the same at both venues, so only the fees differ. At a $4,000 hammer the Idaho all-in is $4,888 on IAAI and $5,213 on Copart, a gap of $325. See the Copart total cost in Idaho, or the three-hammer comparison on the Idaho total cost guide.
