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.
Wisconsin
Wisconsin has one of the simplest fee structures of any large state: a flat $85/year passenger registration with no separate plate fee, a 5% state sales tax with modest local additions (most counties charge 0.5%), and full trade-in credit. The two costly outliers are the $214.50 title fee (the highest in the US after a $50 hike on October 1, 2025) and a steep $175/year EV surcharge. County wheel taxes apply in only 10 of 72 counties — most Wisconsin drivers pay $0 in local wheel taxes. Sales tax tops out around 5.5% in most counties (5% state + 0.5% county), making Wisconsin meaningfully cheaper than Illinois (7-11%) or Iowa (5-7%) for vehicle purchases. A new $35,000 vehicle in a typical wheel-tax-county (like Milwaukee) runs about $2,225 in first-year costs, with annual renewals just $105.
What this means for you
- Buying a new car: Iowa is roughly $89 cheaper than Wisconsin in the first year on a $35K vehicle, driven mostly by sales tax and one-time fees.
- Annual renewal: Wisconsin is cheaper to renew annually by about $260/year. Over a 5-year ownership period that's roughly $1,301 in renewal-fee savings alone.
- If you drive an EV: Iowa's EV surcharge ($130/year) is meaningfully lower than Wisconsin's ($175/year) — a 26% savings on the EV fee alone.
- Structural differences: Neither state imposes an annual ad valorem vehicle property tax, so renewal costs stay relatively flat after the first year for both.
