Iowa splits the job between two offices that never meet. The Motor Vehicle Division writes the rules, prints the forms and keeps the record; a county treasurer takes the paperwork, collects the money and issues the title. Nothing you sign as a seller goes to Ames, and nothing you sign to hand the car over needs a notary. Here is the whole thing, taken from the Iowa Department of Transportation, Motor Vehicle Division's own pages and the forms themselves.
Start hereHow to fill out an Iowa titleThe department's own picture of the assignment side of the redesigned certificate, and the eight entries in it that are yours.Open the walkthrough →Read How to Sell a Vehicle from the top and you meet the mileage twice. Its Selling to an Iowa Dealer section asks for a statement on any vehicle nine model years old or newer, which was Iowa's rule until the last day of 2020. Scroll on and its Odometer Statement section gives the rule that actually applies, keyed to model year 2011. A seller who stops at the first one will decide a 2014 needs nothing this year, and be wrong by five model years.
761 Iowa Admin. Code 400.40(3) is the version to work from, and it is 49 CFR 580.17 as in force on 1 October 2024, copied into Iowa's own rulebook: for transfers happening up to and including 31 December 2030 every vehicle of model year 2011 or newer needs a disclosure, and from 1 January 2031 the exempt line starts moving again at the current year minus twenty. There is no separate Iowa age hiding underneath it.
Model year 2011 and newer, sold at any point before 2031: The reading goes in the mileage box in the assignment area on the back of the certificate, in whole miles, and the buyer signs the same block to say they saw it.
Model year 2010 and older, sold in 2026: Exempt. The federal clock ran out years ago and Iowa asks for nothing, so the box stays empty rather than being filled in for tidiness.
Anything registered above 16,000 pounds gross weight: Exempt whatever its year, and the department only prints that exemption on Form 411099 - none of the web pages mention it.
Iowa Department of Transportation, Motor Vehicle Division, odometer disclosure
You, the seller: Everything you sign is inside one block on the reverse of the certificate, headed ASSIGNMENT OF TITLE. Print the buyer's name and address on the top line, write in the transfer or sale date, tick SALE or GIFT, write the purchase price, fill in the odometer reading if the car is a 2011 or newer, answer the two damage questions, then sign and print your name on the transferor's lines. Then take the plates off the car.
The buyer: The buyer takes that certificate to a county treasurer with Form 411007 and has thirty calendar days to do it. They pay $35 for the title, the fee for new registration, and a prorated annual registration fee.
AND or OR. Two names joined by "and" on the face of the title means both of you sign as sellers. Joined by "or", any one of you may sign alone.
The rule is 761 IAC 400.13(1), and it is worth reading off your own certificate before you agree a completion date. Note the exception, because it is the one that catches people: a replacement title or a junking certificate needs every owner's signature whichever word is printed, connector or no connector. The treasurers' own FAQ still cites this rule as 400.14, which since the June 2025 rewrite of chapter 400 is the paragraph on cancelling a title instead.
Since the stock issued from September 2023 the assignment area carries a TRANSFER/SALE DATE, a SALE or GIFT tick and a PURCHASE PRICE box, so the document that transfers the car is also the document that records what you were paid for it. The department's own answer to a wrong figure is not a correction: the seller needs to obtain a replacement title to assign to the purchaser with the correct amount.

The full box-by-box walkthrough is here, with a printable checklist.
One block on the back of the certificate does the whole job - assignment, sale date, price, mileage and damage - and one optional filing tells the county it happened.
Iowa lets a lender release a lien on the face of the title or on a separate notarised sheet, and which one you get decides how long the sale waits.
Lost, misspelled, signed in the wrong box, or missing a disclosure the buyer needed. Iowa answers each with a different affidavit and three of the four want a notary.
Somebody signing for the owner. Iowa takes a vehicle-specific power of attorney, or a general one propped up by an affidavit, and nothing else.
Two affidavits, one for a will and one without, both notarised, both filed by the person inheriting rather than by an estate.
Junked, salvaged, or a car whose parts are being sold off. These forms end a vehicle's life on the record, and one of them is reversible for exactly fourteen days.
They left the car with you. Now they are either on your next vehicle or on a county treasurer's counter, and one of those two routes is worth money.
Iowa Code s. 321.34 is headed Plates or validation sticker furnished - retained by owner, and the sentence underneath is not a suggestion: the registration plates, including special registration plates, shall be assigned to the owner of a vehicle. When the owner of a registered vehicle transfers or assigns ownership of the vehicle to another person, the owner shall remove the registration plates from the vehicle. The Motor Vehicle Division's own Seller's Checklist puts it first, above the title: remove license plates, turn them in to your county treasurer's office.
You then have two ways to go. Move them within thirty days to a replacement vehicle you have bought, which also carries your unused registration across as a credit, or hand them to any county treasurer and claim the unused months back in cash. The credit route wants the replacement titled within six months; the refund route wants a claim within six months of the sale. Either way there is a floor: under s. 321.126 nothing under ten dollars is paid out, and nothing under ten dollars is credited.
Plates come off an inherited car as well. s. 321.47(3) covers every transfer by operation of law - inheritance, a dissolution decree, a foreclosure, a storage lien sale - and says the registration plates shall be removed and forwarded to any county treasurer.
So how does the buyer get home? Not on your plates. If the car is currently registered, Iowa lets them drive it for thirty days with no plates at all provided they carry a copy of a signed, dated bill of sale describing the vehicle, or a copy of both sides of the assigned title. If it is not currently registered, the treasurer sells them a thirty-day temporary permit for $25, and an out-of-state buyer can have a thirty-day transit plate for $3.
Form 411107, Notice of Sale of Vehicle and Delivery of Title, goes to any county treasurer and Iowa Code s. 321.46(5) is written in the permissive: the seller or transferor MAY file an affidavit. There is no deadline attached to it anywhere in the statute or on the form, and no penalty for never filing one. What it does is narrow and worth having: on the day it arrives the treasurer notes it in the vehicle registration and titling system, and from then on it shall be presumed that the seller or transferor has assigned and delivered the certificate of title for the vehicle.
Read that against what actually protects you, which is s. 321.493(3): a person who has made a bona fide sale and has delivered possession is not liable for damage afterwards, and the purchaser is deemed the owner. That protection turns on handing the car over, not on filing anything - the same section goes out of its way to say the title rules in s. 321.45(2) do not decide the question. The notice is the evidence, not the shield. File it when the buyer is a stranger, when they are driving away without transferring, or when you have any reason to think the title will sit in a glovebox for a month.

Register at any county treasurer's office in Iowa within 30 days of the purchase. No sales tax, because Iowa does not charge any on a vehicle. What the buyer pays instead is the fee for new registration under s. 321.105A - ten dollars plus five per cent of the purchase price - handed to the county treasurer with the application. You collect none of it and you file nothing about it. $35 for the title, being a $30 fee under s. 321.46(2) and a $5 surcharge under s. 321.52A, plus the fee for new registration and an annual registration fee prorated over the months left in the registration year.
What they need to bring:
Iowa runs no emissions programme and no periodic safety inspection, in any county, at any age of vehicle. Nothing in the Motor Vehicle Division's list of what to bring to a title transfer is a test certificate, and there is no windscreen sticker on an Iowa car that can be out of date. One inspection does exist and it is not the seller's and not annual: a vehicle that has been through salvage has to be physically examined by a peace officer certified by the Iowa Law Enforcement Academy before a rebuilt title can be issued, which costs $53 and takes about forty-five minutes. That examination is about stolen parts, not roadworthiness - the officer verifies that no stolen parts were used to rebuild a vehicle - and it happens to the person putting the car back on the road, not to the person selling it.
