Kentucky › Doc fee
Kentucky doc fees: no cap, and what buyers actually pay
What Kentucky allows
- Kentucky does not cap the doc fee. Dealers set it themselves, and there is no legal ceiling to point at.
- Buyers here commonly report around $586.00. That is a market figure drawn from reported deals, not a government number — treat it as a reference point for what is normal, not as a limit.
- The rule: KRS 190.090(8)(d); KRS 190.100(2)(f) -- "processing fee", no dollar cap; the itemized disclosure in 190.100(2)(f) is elective. 605 KAR 1:191 requires the advertised price to include dealer handling..
Is it taxed, and is it negotiable?
- The doc fee is part of the taxable amount in Kentucky, so sales tax is calculated on it as well. A larger doc fee costs you more than the fee itself.
- With no cap in play, the doc fee is simply part of the total you are negotiating. What matters is the out-the-door number, not which line the money sits on.
- Taxed at 6%, a $586.00 doc fee really costs $621.16.
What's specific to Kentucky
- Kentucky does not cap the doc fee, so it is negotiable. The calculator taxes it, because the Department of Revenue treats a documentation or processing fee as part of the sale. The Department has not said so for the usage tax specifically.
