How each state structures it
Illinois
Illinois has one of the highest base passenger registration fees in the country at $151/year, with a similarly high one-time title fee of $165. Combined with sales tax that can hit 10%+ in the Chicago metro area, Illinois is among the most expensive states for vehicle ownership. The state sales tax is 6.25%, but local additions can push combined rates much higher — Cook County and Chicago add roughly 3% combined, putting central Chicago at 9.5-10.25%. Illinois restored full trade-in credit on vehicle sales tax in January 2022 after a brief period (2020-2021) when trade-in credit was capped at $10,000. Electric vehicles pay an additional $100/year surcharge, bringing the BEV registration to $251/year. A new $35,000 vehicle in a 1%-local-rate county runs about $2,850-2,900 in first-year costs; in central Chicago that climbs to $3,900+.
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.
What this means for you
- Buying a new car: Iowa is roughly $1,136 cheaper than Illinois in the first year on a $35K vehicle, driven mostly by sales tax and one-time fees.
- Annual renewal: Illinois is cheaper to renew annually by about $214/year. Over a 5-year ownership period that's roughly $1,071 in renewal-fee savings alone.
- If you drive an EV: Illinois's EV surcharge ($100/year) is meaningfully lower than Iowa's ($130/year) — a 23% 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.
