In short

Iowa is one of the states where a missed car payment does not lead straight to a tow truck. Once you are more than 10 days late, the creditor must mail a notice of right to cure and then wait 20 days before it repossesses or demands the full balance. Dealer contracts are capped at 21% to 27% a year depending on the car's model year, and the dealer documentary fee may not exceed $180. The Iowa Attorney General administers the Iowa Consumer Credit Code.

Right to cure: 20 days after a notice
Rate ceiling: 21% to 27% by car age
Doc fee limit: $180
Vehicle sales tax: 5% registration fee

How much interest an Iowa dealer contract can carry

When a dealer arranges your financing, you sign a retail installment contract, and Iowa Code §322.19 limits what it may charge. The law states the limit as a monthly percentage of the declining balance. The newer the car, the lower the ceiling.

Iowa maximum finance charge on dealer motor vehicle contracts (Iowa Code §322.19), shown for 2026 sales
Vehicle	Monthly limit	Yearly equivalent
New, 2026 model year or later	1.75%	21%
Other new cars; used 2024 to 2026 models	2%	24%
Used, 2023 model year or older	2.25%	27%

A ceiling is the most a dealer may charge, not the rate you should expect. Buyers with solid credit often see far less. Before you sign, put the quoted APR into the car payment calculator and look at the total interest, not only the monthly payment. Banks and credit unions that lend to you directly follow their own charters and rules.

The Iowa Consumer Credit Code, which gives you the cure right described below, covers consumer credit up to the federal Truth in Lending threshold. That dollar limit is adjusted each year, so check it if you finance an unusually expensive vehicle.

Fees and taxes on an Iowa purchase

Documentary fee. An Iowa dealer may charge no more than $180 per vehicle for preparing title and registration papers. The fee must be part of the advertised price, and the purchase agreement must carry a notice saying it is not an official fee.
Fee for new registration. Iowa charges a one-time fee of $10 plus 5% of the purchase price when the car is first registered to you.
Trade-in. A trade-in taken by the dealer lowers the price the 5% applies to, as long as the same person is on both titles (spouses and some family members are allowed).
Add-ons. A service contract or debt cancellation coverage may be included in the amount financed, which means you pay interest on it.

What happens if you fall behind in Iowa

Under Iowa Code §537.5109, you are in default when a payment is more than 10 days late, or when you break another term in a way that seriously harms the collateral or your ability to pay. For a missed payment, §537.5110 then slows the creditor down.

The cure notice. Before it repossesses or sues, the creditor must send you a written notice of your right to cure.
Twenty days to catch up. For 20 days after that notice, it may not take the car or accelerate the loan. Paying the missed installments and any late charges puts the contract back as if you had never defaulted.
Only once a year. If you already received a proper cure notice in the past 365 days, the next default carries no new cure period.
After the 20 days. The creditor may repossess without going to court, as long as it does not breach the peace. Before selling the car it must send a notice of the sale, and until the sale you may redeem by paying what you owe.
The balance after the sale. You owe a deficiency only if the creditor sold the car in good faith and in a commercially reasonable way (§537.5103).

A creditor that sues you for money without following these steps must have its case dismissed. If you are already behind, read our guides on what to do when you fall behind and how repossession works.
