How each state structures it
Kentucky
Kentucky has a three-part vehicle cost structure: a small flat registration fee ($21/year), a 6% Motor Vehicle Usage Tax collected once at title transfer (Kentucky's name for sales tax), and an annual ad valorem property tax that varies significantly by county. The combined state + county + city + school district millage typically averages around $1.30 per $100 of NADA value, giving effective rates near 1.30% of vehicle value statewide. Notably, HB108 of 2026 begins a phased reduction of the STATE portion (currently 40¢/$100) down to 5¢/$100 by 2033, with complete elimination of the state portion in 2034 — but county and city portions are unaffected. EV and PHEV surcharge is $126/year (2025 rate per AFDC, indexed annually). A new $35,000 vehicle in a typical Kentucky county runs about $2,556 in first-year costs, with annual renewals around $407 dropping as the vehicle depreciates.
Ohio
Ohio has a relatively simple flat-fee registration system: $31/year base for any passenger vehicle, regardless of age, weight, or value, plus a county-level "permissive tax" that can add up to $30/year for local road maintenance. The state sales tax is 5.75% with a county addition ranging from 0.75% to 2.25%, putting combined rates in the 6.5% to 8.0% range depending on county. Ohio charges substantial EV-related fees — $200/year for battery EVs, $150 for plug-in hybrids, $100 even for conventional hybrids — to recover lost gas tax revenue. A new $35,000 vehicle in a typical Ohio county runs about $2,200-2,250 in first-year costs, with annual renewals around $51 for gas vehicles or $251 for EVs.
What this means for you
- Buying a new car: Kentucky is roughly $94 cheaper than Ohio in the first year on a $35K vehicle, driven mostly by sales tax and one-time fees.
- Annual renewal: Ohio is cheaper to renew annually by about $307/year. Over a 5-year ownership period that's roughly $1,536 in renewal-fee savings alone.
- If you drive an EV: Kentucky's EV surcharge ($126/year) is meaningfully lower than Ohio's ($200/year) — a 37% savings on the EV fee alone.
- Structural differences: Kentucky charges an annual ad valorem property tax on vehicles (renewals stay expensive as long as you own the car), while Ohio does not — over a 10-year hold this can swing thousands of dollars toward Ohio.
