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.
Missouri
Missouri's vehicle costs have an unusual shape: small state DMV fees (typically $33/year registration based on taxable horsepower, $11 title, $11 plate), but a meaningful annual personal property tax assessed by counties at roughly 1.8% effective rate (state average, after the 33⅓% assessment ratio) on the vehicle's NADA value. The property tax is the dominant ongoing cost: a $35,000 vehicle in St. Louis County (~6% county rate) pays about $595/year in property tax alone, dropping as the vehicle depreciates. Sales tax is 4.225% state plus local 0-5.875% — Missouri requires buyers to pay sales tax at their local DOR office within 30 days of purchase, not at the dealer. Missouri is one of about 20 states with no EV surcharge as of 2026. A new $35,000 vehicle in a typical Missouri county runs about $3,535 in first-year costs, with annual renewals around $568.
What this means for you
- Buying a new car: Kentucky is roughly $953 cheaper than Missouri in the first year on a $35K vehicle, driven mostly by sales tax and one-time fees.
- Annual renewal: Kentucky is cheaper to renew annually by about $144/year. Over a 5-year ownership period that's roughly $718 in renewal-fee savings alone.
- If you drive an EV: Kentucky's EV surcharge ($126/year) is meaningfully lower than Missouri's ($150/year) — a 16% savings on the EV fee alone.
- Structural differences: Both states levy an annual ad valorem tax on vehicles, so neither offers a long-term renewal advantage from this structure.
