Overview
The first-year bill has two more pieces. The title fee is $35 (it was $25 until House File 674 raised county-treasurer fees on January 1, 2025), plus a lien notation fee of $20 if you're financing. Then there's the annual registration itself - and this is the part almost nobody expects: it's not based on what you paid. Iowa charges 1% of the vehicle's original list price (declining to 0.75%, 0.5%, then a flat $50 as the car ages) plus $0.40 per 100 pounds of weight. Two people who paid wildly different prices for the same model and trim pay the identical registration bill.
On a private-party sale, keep your bill of sale - if your reported price looks far below the vehicle's NADA or Kelley Blue Book value, the county treasurer can assess the 5% fee against that book value instead. The calculator below totals all four pieces for your purchase.

How to title and register a vehicle in Iowa
- 1
Get the title properly signed over by the seller, with a bill of sale showing the price, date, and both parties' names.

Bring the title, bill of sale, proof of Iowa insurance, and ID to your county treasurer within 30 days of the sale.
- 3
The treasurer calculates the Fee for New Registration off your price minus any documented trade-in - or off NADA/KBB value if your price looks unusually low.

Pay the fee for new registration, the $35 title fee, and the first year's value + weight registration in one transaction.

Plates or a validation sticker are issued on the spot in most counties; a lienholder's name gets noted for another $20.

Iowa tax, title & license FAQ
How much is tax, title and license on a $25,000 car in Iowa?
Roughly $1,510–$1,800 depending on the car's original list price and weight: about $1,260 for the fee for new registration ($10 + 5% of $25,000), $35 for the title, and $200–$500 for first-year registration based on the vehicle's factory list price and weight class.
Is Iowa's 5% fee really not sales tax?
Correct - legally it's a registration fee under Iowa Code 321.105A, not a sales tax, which is why Iowa has no state sales tax on cars. It functions almost identically to one (and the IRS lets you deduct it like a sales tax if you itemize), but because it's collected by the county treasurer instead of the Department of Revenue, some out-of-state paperwork and reciprocity questions get confusing.
Does a trade-in actually reduce what I owe?
Yes - the fee for new registration is 5% of price minus your trade-in's documented value minus any manufacturer rebate, whether you're buying from a dealer or trading vehicles with a private party. Get the trade-in value written on the bill of sale or purchase agreement.
Why is my registration bill based on the sticker price of a new car, not what I actually paid?
Iowa's annual registration formula uses the vehicle's original manufacturer list price (its MSRP when new), not your purchase price or current resale value. A heavily discounted new car and one bought at sticker price register for exactly the same annual fee - only the age and weight change it going forward.
What if I miss the 30-day deadline?
A flat $10 penalty applies once you're past 30 days on the title, on top of whatever fee for new registration and registration fees you already owe - Iowa doesn't escalate the title penalty monthly the way some states do.
I bought a used car privately for way less than it's worth - what happens?
Your county treasurer can compare your reported price against NADA or Kelley Blue Book. If your price looks implausibly low, they can charge the 5% fee against the book value instead of your bill of sale. Keep documentation (repair needs, accident history) if there's a legitimate reason the price was low.
