Out-the-door price in Ohio

How Ohio works

  • Ohio sales tax is based on the county you live in, not where the dealership is — the clerk of courts collects it at titling using your county of residence rate. Rates run 6.50% to 8.00% and change quarterly.
  • Your trade-in only reduces the taxable amount when you are buying a NEW vehicle from a new-car dealer. On a used or certified pre-owned purchase, Ohio taxes the full price with no trade-in credit.
  • Manufacturer rebates are taxed in Ohio — tax is figured on the price before the rebate. A dealer's own cash discount does lower your taxable price.
  • The dealer's documentary fee is NOT subject to sales tax in Ohio, and it is capped at the lesser of the current CPI-adjusted amount or 10% of the contract price.
  • Extended warranties, service contracts and GAP are taxable when sold as part of the vehicle purchase agreement. Buying them later in a separate transaction is treated differently.
  • Registering the car: in Ohio you can register it and get plates yourself at a deputy registrar before your 45-day temporary tag runs out. Or the dealer can do it for you: for a registration service fee (up to $50 with titling, and the registration part has to be labeled optional), or at the sale for the usual $8 deputy registrar fee if the dealer is a limited-authority deputy registrar. Registration isn't in the calculator's total; the notes with your result show what to budget.
  • If you live in Delaware, Fairfield, Licking, Union or Wood County, your rate can be 0.50 to 1.00 point higher than shown when your address falls inside the COTA or TARTA transit district. Check your exact address at thefinder.tax.ohio.gov.

My price already includes…

Federal law says a dealer's advertised price should include every fee the dealer charges, so where we've checked a state's rules we tick the ones that apply there for you. Untick any your price doesn't cover, so nothing is missed or counted twice.

What an Ohio advertised price has to include

Ohio's Attorney General rule already requires a dealer's advertised price to include every cost to you except tax, title and registration fees and the doc fee. The FTC expects more: every fee the dealer charges, the doc fee included, belongs in the advertised price, so only government charges like tax, title, registration and the temporary tag can be added on top. That still isn't your out-the-door number; the calculator above adds the rest for your ZIP.

Federal law comes first

The FTC requires a dealer's advertised price to include every fee the dealer charges. Only charges the government requires you to pay, like tax, title and registration, can be left out. Where a state's rules let a dealer leave a fee out, the dealer still has to follow the federal rule, so the fee goes in. The FTC says a state's doc-fee rules can add disclosures, but they don't change the price that has to be advertised. Read the FTC's guidance.

Ohio law and the FTC conflict

Ohio's Attorney General rule lets a dealer leave the doc fee out of an advertised price, as long as it's within the legal cap, and an Ohio BMV rule says the dealer's title or registration service fee (up to $50) can't be in the advertised price at all. The FTC expects every fee a dealer requires to be in the advertised price. Until regulators or the courts settle it, you may see Ohio ads that leave them out. Ask whether a price includes them, and get the out-the-door price in writing.

What the FTC expects in the advertised price

  • The doc fee (at most $398 in 2026 and $412 in 2027, and never more than 10% of the price)
  • Freight (destination) and dealer preparation charges
  • Anything the dealer has added to the car, such as accessories and add-on packages
  • A title or registration service fee (up to $50), if the dealer charges it on every sale
  • Any other charge the dealer requires

Can still be added on top

  • Sales tax (5.75% plus your county's rate)
  • The title fee ($18, or $23 in five counties) and the $23 temporary tag
  • Registration and plates, which you usually buy yourself at a deputy registrar
  • Optional products you choose to buy, such as a service contract or GAP coverage

Ohio OTD questions, answered

Does a trade-in reduce sales tax in Ohio?

Yes — Ohio taxes the difference: your trade-in's value is subtracted before tax is computed.

Are manufacturer rebates taxed in Ohio?

Effectively yes — tax is computed before the rebate is applied, so you pay tax on the pre-rebate price.

Is the doc fee capped in Ohio?

Yes — the cap is $398.00 (Ohio Rev. Code Sec. 4517.261(B)-(C) (lesser of CPI-adjusted amount or 10% of contract price, excl. tax/title/registration)). A dealer may not exceed it.

What does an Ohio dealer's advertised price have to include?

Every cost to you except tax, title and registration fees and the doc fee (Ohio's rule), plus the doc fee itself and every other fee the dealer requires (the FTC's position; Ohio lets dealers leave the doc fee out, so the two conflict). Only sales tax, the title fee, registration, the temporary tag and other government charges can be added on top.

Can an Ohio dealer charge a title or registration service fee?

Yes, up to $50 plus mailing since March 2026, for e-filing your title through a paid provider or taking your paperwork to the deputy registrar. It has to be disclosed in writing, and the registration service has to be labeled optional. Ohio's rule keeps it out of the advertised price; under federal law, a dealer that charges it on every sale should include it.
