Ohio car-buying rules
These are the rules the Before the Lot planner uses for Ohio, with the source and date for each. They describe the rules and the planner's estimate; they are not legal or tax advice, and the dealer's quote and your state's documents are what count.
Dealer doc fee in Ohio
Cap: $398 or 10% of the sale, whichever is less.
- Next scheduled figure: $412 from January 1, 2027.
- How the figure changes: yearly (CPI); set each Sept 30 for the next calendar year.
- Law: Ohio Rev. Code 4517.261 (as amended by SB 94, eff. Oct 24, 2024); 1317.07.
- The figure is worked out from the statute's formula; the state's own posting of it was not found.
The lesser of $398 (calendar 2026) or 10% of what the buyer or lessee pays, excluding tax, title, registration and negative equity. Applies to every sale and lease, cash included. The statute sets the formula, not the figure: $250 plus the CPI-W change since July 2006, set each Sept 30 for the next year, never going down. Recomputed from BLS data: $398 for 2026 and $412 for 2027 (the registrar's posting wasn't found). Separately, an optional 'customer convenience fee' of up to $50 per vehicle (plus mailing costs) for registration or title services is allowed (OAC 4501:1-6-12, eff. Mar 1, 2026).
Sales tax in Ohio
- Tax: Sales and use tax (state + county).
- State rate used: 5.75%.
- Local add-ons: Up to 2.25% on top of the state rate.
- Dollar cap on the tax: none in the data.
Plus your home county's rate (6.5%-8% total). Trade-in credit only on a new car from a new-car dealer.
Your local rate
Local tax on a car goes by where the buyer lives. Find your exact rate: Ohio official lookup (The Finder (Sales Tax lookup)).
Trade-in tax credit
Yes. Ohio takes the trade-in value off the taxed price.
Does a maker's rebate lower the taxed price?
No. (H)(1)(b) includes consideration from third parties. No Ohio vehicle guidance found; Sales Tax Handbook (secondary) agrees. Trade-in credit only on new vehicles from new-car dealers. Confidence in this entry is low.
Cancellation and return rights
No Ohio-specific right to cancel or return a dealership purchase is in the planner's data.
There is no federal cooling-off period for buying a car at a dealership; the FTC's door-to-door Cooling-Off Rule excludes dealers with a permanent place of business (16 CFR 429.3(a)). The FTC CARS Rule was vacated by the Fifth Circuit in January 2025 and formally withdrawn effective Feb 12, 2026 (91 FR 6507). No other state with a general used-car cooling-off right was found; NCLC calls California's the first in the nation.
Worked out-the-door example: a $35,000 vehicle
Built with the planner's own out-the-door formula: the tax is the state base rate times the vehicle price plus the doc fee, with no trade-in, rounded to the cent. Local taxes are not included.
| Line | Amount |
|---|---|
| Vehicle price (example) | $35,000 |
| Doc fee (the Ohio cap) | $398 |
| Sales tax at 5.75% on $35,398 | $2,035.39 |
| Title and registration (the planner's default estimate) | $250 |
| Out-the-door total | $37,683.39 |
Title and registration fees differ by state and vehicle; $250 is a placeholder, not an Ohio figure.
