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.
Tennessee
Tennessee has one of the more distinctive sales tax structures in the US: 7% state tax on the FULL purchase price, plus a "single article tax" of 2.75% on the portion between $1,600 and $3,200 (max $44), plus local sales tax of 2.25-2.75% applied ONLY to the first $1,600 of purchase. The combined effective rate on a typical $35,000 vehicle works out to roughly 7.2% — counterintuitively LOWER than the headline 9.25-9.75% you'd see in retail stores, because local tax doesn't scale with vehicle price. Beyond sales tax: $29/year state registration, county wheel taxes from $0 to $55 (36 of 95 counties have none), $14 title fee, and a stiff EV surcharge of $200/year (rising to $274 in 2027). Tennessee has no state income tax, so vehicle fees and the gas tax carry more weight in funding state operations. A new $35,000 vehicle in Davidson County (Nashville, $55 wheel tax) runs about $2,617 in first-year costs; in a no-wheel-tax county that drops to about $2,562.
What this means for you
- Buying a new car: Kentucky is roughly $56 cheaper than Tennessee in the first year on a $35K vehicle, driven mostly by sales tax and one-time fees.
- Annual renewal: Tennessee is cheaper to renew annually by about $303/year. Over a 5-year ownership period that's roughly $1,516 in renewal-fee savings alone.
- If you drive an EV: Kentucky's EV surcharge ($126/year) is meaningfully lower than Tennessee'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 Tennessee does not — over a 10-year hold this can swing thousands of dollars toward Tennessee.
