How each state structures it
Iowa
Iowa's annual registration combines a small weight component ($0.40 per 100 lbs — about $15/year for typical passenger cars) with a value-based portion: 1.00% of original MSRP for years 1-6, dropping to 75% (years 7-9), 50% (years 10-11), then a $50 flat minimum from year 12+. So a new $35,000 vehicle pays about $365/year in registration ($15 weight + $350 value), dropping to $278 by year 7 and $50 by year 12. Sales tax is replaced by the "Fee for New Registration": $10 base + 5% of purchase price minus trade-in, with NO local additions — Iowa is one of the few states with completely uniform vehicle purchase tax. Title fee is $25, plate fee $5. EV surcharge is $130/year. A new $35,000 vehicle runs about $2,165 in first-year costs, with annual renewals around $365 dropping over the age tiers.
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: Iowa is roughly $1,314 cheaper than Missouri in the first year on a $35K vehicle, driven mostly by sales tax and one-time fees.
- Annual renewal: Iowa is cheaper to renew annually by about $141/year. Over a 5-year ownership period that's roughly $703 in renewal-fee savings alone.
- If you drive an EV: Iowa's EV surcharge ($130/year) is meaningfully lower than Missouri's ($150/year) — a 13% savings on the EV fee alone.
- Structural differences: Missouri charges an annual ad valorem property tax on vehicles (renewals stay expensive as long as you own the car), while Iowa does not — over a 10-year hold this can swing thousands of dollars toward Iowa.
