Iowa Vehicle Bill of Sale — What It Needs & Check First

An Iowa bill of sale records the full names and addresses of the buyer and seller, the sale date, the purchase price, the vehicle's year, make, model, and body style, the exact odometer reading, and the 17-character VIN. Both parties sign it. Iowa does not publish an official form, so any written bill of sale carrying those details is acceptable. Confirm the VIN on the bill of sale matches the title and the dashboard before signing — and run a free VIN check first to verify the title is clean and lien-free.

Yes. Iowa law requires a signed bill of sale for every title transfer, including gifts, but the state issues no numbered form — the county treasurer's office that handles your title supplies one. The signed-over title remains the primary ownership document; the bill of sale is the dated proof of purchase the Iowa Department of Transportation uses to confirm the sale and calculate any tax due.

Sometimes. The Iowa bill of sale is normally signed without a notary, but the form itself warns that 'Errors or alterations on the title or other documents presented for title transfer may require this form to be notarized', and it carries a notary block for that situation.

30 days from the date of sale. Iowa Code section 321.46(1) is unusually precise: 'The transferee shall, within thirty calendar days after purchase or transfer, apply for and obtain from any county treasurer a new initial registration and a new certificate of title for the vehicle.' Penalties apply after day 30. The buyer may drive the vehicle for those 30 days on the seller's existing registration provided the assigned title and proof of insurance are in the vehicle. This is the buyer's deadline to apply for title — a seller's duty to report the sale, where one exists, runs on a separate clock.

Iowa publishes no form of its own, which puts it with 15 states against 25 that issue one. On whether the document is required at all, the country splits 8 always, 23 sometimes and 11 never, out of the 42 states publishing a rule. Notarization is the real outlier: 23 states say it is not needed, 10 require it in certain transfers, and 2 require it every time (Louisiana and West Virginia).

Not in most of the country. Of the 35 states where the rule is published, 23 do not require notarization, 10 require it for particular transfers, and 2 require it on every one — Louisiana and West Virginia. Iowa is in the middle group: some transfers need it and some do not, so resolve which case applies before the meeting. The advice that "a bill of sale must always be notarized" is a rule from somewhere else, repeated without its state attached.

It is the commonest deadline in the country. Across the 34 states that publish a calendar-day deadline for the buyer, the figure runs from 10 days to 60, and 30 days is the commonest single answer — 18 states use it. 10 states give buyers less time than Iowa does and 6 give more. The clock starts on the date written on the bill of sale, so do not backdate it to cover a delay: that shortens your own deadline. Where the car had a loan, the real constraint is usually how long the lender takes to send a lien release, not the Iowa Department of Transportation's deadline.

Usually yes for the document itself — a bill of sale is a record of a transaction, and Iowa does not reject one because it was typed on another state's template. What does not travel is the procedure around it: 2 states require notarization and the rest largely do not, deadlines to apply for title range from 10 to 60 days, and 25 states publish a form with fields the other 25 never ask for. If you are buying across a state line, the rules that bind you are the ones where the car will be titled, not the ones where it was sold. Run the VIN before you cross the line either way — a brand applied in one state follows the car into the next.

Besides the bill of sale, you'll typically need the Iowa title signed over by the seller, an odometer disclosure (often part of the title or bill of sale), a lien release if the car had a loan, and your own proof of identity and insurance to register it with the Iowa Department of Transportation. A free VIN history check isn't legally required, but it's the smartest document to add — it confirms the title is clean before money changes hands.

The bill of sale records what the seller claims; a VIN check shows what actually happened to the car. Running the 17-character VIN before you sign confirms the title is clean, the odometer reading is consistent with the car's history, and there's no open lien that would block the transfer at the Iowa Department of Transportation. It's free and takes seconds.

Iowa law requires that flood-damaged vehicles be permanently branded on the title to protect future buyers.
