IAAI Car Total Cost in South Dakota (2026)

IAAI in South Dakota: four hammer prices

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

What the IAAI side of a South Dakota bill is made of

IAAI's side of the South Dakota 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 South Dakota 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.
