Overview
The rule that trips up the most buyers: trade-ins only lower your tax bill when you're buying a NEW vehicle. Ohio Administrative Code 5703-9-36 is explicit that used-vehicle purchases - whether from a dealer or a private seller - get no deduction for a trade-in's value; you're taxed on the full price of the used car regardless of what you handed over. Private/casual sales are taxed on the stated price, but the county can substitute a fair-market estimate (KBB/NADA) if that price looks implausibly low. Genuine gifts, with no money changing hands, owe no sales tax at all.

Ohio car sales tax FAQ
Is it true Ohio doesn't give a trade-in credit on used cars?
Yes. Ohio Administrative Code 5703-9-36 spells out that the trade-in allowance reduces the taxable price only on a new-vehicle purchase. Buy a used car and trade in your old one - at a franchise dealer or a private seller - and you owe tax on the used car's full price with no offset.
How much is sales tax on a $20,000 used car in Ohio?
Between $1,300 (6.5%, in Butler, Lorain, Stark, or Wayne County) and $1,600 (8%, in Cuyahoga or Franklin County) - on the full $20,000, since a trade-in doesn't reduce a used-car tax base in Ohio.
Which Ohio counties have the highest and lowest combined rates?
Cuyahoga (Cleveland) and Franklin (Columbus) sit at the top with 8%, partly from added transit levies. Butler, Lorain, Stark, and Wayne counties sit at the bottom with 6.5%. Most of Ohio's other 84 counties land around 7.25%.
Do I pay Ohio tax based on where I bought the car or where I live?
Where you live. A dealer in a low-tax county still has to charge you the rate for your county of residence when you register the vehicle there - the dealer's location doesn't set the rate.
Can the county tax me on more than what I actually paid?
On a private/casual sale, yes if your stated price looks implausible - the clerk of courts can reference Kelley Blue Book or NADA and assess tax on the vehicle's fair market value instead of your number. Keep a bill of sale that reflects the real price and condition.
Is a car gifted between non-family members still tax-free?
The exemption is for transfers with no consideration exchanged, not strictly a family-only rule - a genuine no-money gift to anyone should owe no sales tax, though the clerk of courts may ask for a signed statement or exemption certificate for anything that isn't an obvious family transfer.
