How much is sales tax on a car in Ohio?

You pay the combined state-and-county rate for the county where you register the vehicle, sitting between 6.50% and 8.00%. On a $25,000 car that is $1,625 to $2,000 in sales tax.

Does a trade-in reduce sales tax in Ohio?

Yes, for both new and used vehicles bought from a licensed dealer. Under Ohio RC 5739.01, the trade-in allowance is subtracted from the purchase price before sales tax is calculated. However, this deduction does not apply to private-party sales — if you buy from a private seller, you pay tax on the full price.

Which county's rate applies to my car?

The county where you title and register the vehicle—normally your county of residence—not the county where the dealership sits.

Do rebates lower the sales tax?

No. Manufacturer rebates are applied after sales tax is calculated and do not reduce the taxable purchase price in Ohio. However, any discount already reflected in the negotiated vehicle price does reduce the taxable base since you're paying a lower price upfront.

What other fees should I expect?

A flat $15 title fee, plate and registration fees through the BMV, and a dealer documentation fee that Ohio heavily caps. This tool includes the title fee and lets you add a doc fee.

Is a private-party (used) car purchase taxed?

Yes. When you title a used vehicle bought from a private seller, you pay use tax at your county's combined rate on the exact purchase price right at the clerk of courts title office.

Ross County How Ohio Taxes a Vehicle Purchase

Ohio taxes a vehicle at the combined rate of the county where you register it, not where you buy it. Under Ohio RC 5739.01, when you trade in a vehicle at a licensed dealer, the trade-in allowance reduces the taxable base for BOTH new and used vehicle purchases. You only pay tax on the difference. A flat $15 title fee applies on top. Note: the trade-in deduction does not apply to private-party (non-dealer) sales.

Taxable Base = Purchase Price − Trade-In Allowance
Sales Tax = Taxable Base × Combined County Rate

Example: A $30,000 car in Franklin County (8.00%) with a $10,000 trade-in has a taxable base of $20,000: $20,000 × 0.08 = $1,600 in tax. Without a trade-in, you'd pay $30,000 × 0.08 = $2,400. The $10,000 trade-in saves you $800 in tax regardless of whether the car is new or used.

Worked Examples

$30,000 car, $10,000 trade-in, Franklin (8.00%)($30,000 − $10,000) × 0.08$1,600.00 tax

$30,000 car, no trade-in, Franklin (8.00%)$30,000 × 0.08$2,400.00 tax

$25,000 car, no trade-in, Butler (6.50%)$25,000 × 0.065$1,625.00 tax

$18,000 used car, $3,000 trade-in, Cuyahoga (8.00%)($18,000 − $3,000) × 0.08$1,200.00 tax

Sales tax on a $25,000 vehicle by combined county rate (before any trade-in credit).
