What Is Ohio Sales Tax on Cars? Rates, Trade-Ins, and Exemptions

Ohio sales tax on cars runs between 6.50% and 8.00% of the purchase price, depending on the county you live in. The state charges a base rate of 5.75%, and every county adds its own local tax on top.¹ The tax applies to almost every vehicle transfer, including dealer sales, private sales, leases, and gifts.

What Determines Your Rate

The 5.75% state rate is uniform across all 88 counties. Counties and regional transit authorities layer their own levies on top, which is why the combined rate varies.² Cuyahoga County (Cleveland) and Franklin County (Columbus) sit at the top with 8.00%. Several rural counties sit at the 6.50% floor.³ On a $30,000 car, the difference between the lowest and highest rate works out to $450.

The rate is set by where you live, not where you buy. If you live in Franklin County and drive to a neighboring county with a lower rate to shop, you still owe the Franklin County rate when you title the vehicle.⁴ The same residency rule applies to auction purchases, where tax is calculated on the bid amount plus any fees or commissions.²

Trade-In Reduces the Taxable Price Only on New Cars

If you trade in a vehicle when buying a new car from a licensed new-car dealer, the trade-in value is subtracted from the purchase price before sales tax is calculated. Ohio law defines the taxable “price” of a new motor vehicle sold by a new motor vehicle dealer as the total consideration minus the credit given for the trade-in.⁵ Buy a $35,000 new car and trade in your old one for $10,000, and you pay tax on $25,000.

This is where many buyers get surprised. The deduction applies only to new motor vehicles bought from new-car dealers. On a used car, even one bought from a franchise dealership, Ohio’s general definition of “price” does not allow a trade-in deduction.⁵ You owe tax on the full purchase price regardless of what you traded in.

Private Sales, Gifts, and Price Checks

Private party sales are fully taxable. Motor vehicles are specifically excluded from Ohio’s casual sale exemption, so you owe the same rate whether you buy from a dealer, a private seller, or receive a car as a gift.¹ There is no family exemption. A parent gifting a car to a child still triggers sales tax when the title changes hands at the clerk of courts.

The Ohio Department of Taxation also watches reported prices on private sales. It compares the price you report to the average selling price of similar vehicles (same make and model) in Ohio. If your stated price is significantly below the average, you may receive a questionnaire asking you to justify it. Keep the bill of sale, records of the car’s condition, and proof of payment in case you need to respond.

Leased Vehicles

Leasing a vehicle in Ohio triggers sales tax on the total amount you will pay over the initial lease term, not on each monthly payment. The full tax is due when you sign the lease.¹ If you later renew the lease, tax on the renewal payments is collected as each payment comes due. The leasing company collects the tax at your county of residence rate and remits it to the clerk of courts.⁶ For an open-end lease without a guaranteed end date, tax is calculated on the total due during the initial fixed term and then recalculated for each renewal period.

Buying a Car Out of State

If you buy a car in another state and bring it home, you owe Ohio use tax at your county’s combined rate when you title the vehicle. Ohio’s use tax mirrors the sales tax so that out-of-state purchases are taxed the same as in-state ones.⁷

You get a credit for any sales or use tax you already paid to the other state. If their rate was lower than your Ohio county rate, you pay the difference. If you paid an equal or higher rate, you owe nothing more. Pay 6% in another state when your county rate is 7.50%, and you owe the remaining 1.50% when titling the vehicle.⁷

When and How You Pay

Where the tax goes depends on who sold you the car. A dealership collects the sales tax at the time of sale, handles the title paperwork, and remits the tax to the clerk of courts when the title is issued.⁸ For a private purchase, you pay the tax yourself at a county clerk of courts title office when you apply for the certificate of title.⁴ The clerk calculates the tax from your purchase price and county of residence. Cash, check, and credit card are accepted, though credit card payments typically carry a 2.5% to 3% processing fee.⁹

You have 30 days from the date of sale to complete the title transfer. Miss that window and a $5 late fee is added on top of the tax owed.⁹ The fee itself is small, but delaying the title also delays your registration, which puts you at risk if you are pulled over without valid plates.

Narrow Exemptions

Ohio exempts only a handful of vehicle categories from sales tax, all tied to specific commercial or agricultural use:

Vehicles used directly in farming operations
Vehicles purchased for a for-hire transportation business
Vehicles used directly by regulated public utilities
Vehicles used directly in manufacturing processes

None of these apply to personal vehicle purchases, and the buyer claiming an exemption bears the burden of proving the vehicle qualifies.
