Bill of Sale Aug 21, 2026
Selling a car in your driveway or buying one from a stranger you met online feels a little different in Kansas than in most states. There is no statewide law forcing every private sale onto a notarized form, but county treasurer offices still expect specific paperwork before they will hand over a title. This guide walks through exactly what a Kansas bill of sale needs to say, when the state actually requires one, and how to avoid the small mistakes that slow down title transfers.
What Is a Kansas Bill of Sale?
A Kansas bill of sale is a short written record of a vehicle sale between two parties. It captures who sold the car, who bought it, what the car is, how much it sold for, and when the sale happened. Think of it as a receipt with legal weight — it is not the same thing as the title, but county treasurer staff often lean on it to confirm a sale price or fill a gap the title itself does not cover.
The Kansas Department of Revenue (KDOR), Division of Vehicles, provides an official form for this purpose — Form TR-312 — though a handwritten or typed bill of sale is accepted as long as it includes the same required details.

When Do You Need a Bill of Sale in Kansas?
A bill of sale becomes necessary in a few common situations:
• The vehicle's title does not have a space to record the purchase price
• You are titling an antique vehicle (35 model years or older) and there is no existing Kansas title
• The county treasurer requests proof of the sale price for tax purposes
• You bought the vehicle out of state and the seller only provided a bill of sale rather than a signed title
In most everyday private sales where the Kansas title already has a completed assignment section on the back — including purchase price, date, odometer reading, and signatures — a separate bill of sale is not strictly mandatory. Still, county offices commonly recommend keeping one as a backup record.

What Information Must a Kansas Bill of Sale Include?
Whether you use Form TR-312 or write your own, Kansas expects the same core details. Missing even one line — like the VIN or a printed name next to a signature — is the most common reason county staff send buyers back home to redo paperwork.
| Section | Required Detail |
|---|---|
| Buyer information | Full legal name and complete mailing address |
| Seller information | Full legal name and complete mailing address |
| Vehicle details | Year, make, model, and Vehicle Identification Number (VIN) |
| Sale details | Purchase price and exact date of sale |
| Odometer reading | Mileage at the time of transfer (required for most vehicles under 20 years old) |
| Signatures | Handwritten signature of the seller and the buyer, with printed names |

Kansas Bill of Sale vs. the Vehicle Title: What's the Difference
A title is the legal proof of ownership. A bill of sale is proof that a transaction happened. In Kansas, the back of a standard title already includes fields for purchase price, sale date, odometer reading, and both signatures — which is why a separate bill of sale is often optional rather than required. The title must always be assigned to the new owner regardless of whether a bill of sale exists alongside it.

Confirm the VIN on the title matches the vehicle before any money changes hands.
Both parties print and sign, and the seller records the odometer reading and sale price.
Use Form TR-312 if the title lacks a price field, is an antique, or the county requests it.
If a lienholder is listed, get a notarized lien release, Form TR-150, or a letter from the lienholder.
Apply for title and registration in the county where the vehicle will be located or garaged.
Bring proof of insurance and be ready to pay state and local sales tax plus title and registration fees.

Do You Need to Notarize a Bill of Sale in Kansas?
No — for the vast majority of private sales completed inside Kansas, the Division of Vehicles does not require title assignments, title applications, or bills of sale to be notarized. The department reserves the right to ask for notarization in unusual circumstances, and a few specific documents are the exception: a release of lien, lienholder consent, and the lienholder's portion of Form TR-42 must be notarized.

Sales Tax on Private Vehicle Sales in Kansas
Kansas charges a flat 6.5% state retailers' sales tax rate on vehicle purchases, private-party sales included. On top of that, cities, counties, and special taxing districts can each add their own local rate, so the combined amount a buyer actually pays depends entirely on where the vehicle will be registered.

Odometer Disclosure Requirements
Kansas requires an odometer reading on nearly every vehicle transfer. If the title's odometer section is already full, doesn't apply, or the vehicle is being transferred without a title through a legal document, the state provides a dedicated Odometer Disclosure Statement — Form TR-59 — to record the reading separately.

Vehicle Inspections (MVE-1) for Out-of-State Purchases
If the vehicle you're buying carries an out-of-state title, or the seller only has a bill of sale rather than a Kansas title, expect an extra step: a Motor Vehicle Examination. The vehicle must be taken to a Kansas motor vehicle inspection station, where an examiner checks it and issues Form MVE-1. The pink copy of that form goes to the county treasurer's office along with your title application.
• Required when the vehicle is titled out of state or in another country, regardless of age
• Required when a trailer or vehicle was purchased out of state on a bill of sale
• Required for antique vehicles (1950 or newer) titled in Kansas on a bill of sale rather than a title

Title Transfer Deadline and Penalties
Once a sale is complete, the clock starts running. Kansas requires the buyer to apply for title and registration within 60 days of the purchase date at the county treasurer's motor vehicle office in the county where the vehicle is located or garaged. Miss that window and a penalty applies starting on day 61.

Common Mistakes to Avoid
• Leaving the VIN, price, or odometer reading blank on the title or bill of sale
• Forgetting that all listed owners must sign when the title shows "and" between names
• Assuming a lien is automatically cleared — a written release or Form TR-150 is still required
• Waiting past the 60-day window and getting hit with a late penalty
• Skipping proof of insurance when applying for registration

Final Thoughts
Kansas keeps its bill of sale rules relatively light compared to states that mandate notarization on every private sale, but the trade-off is that buyers and sellers need to get the title paperwork itself exactly right. Double-check the VIN, don't skip signatures, and file within 60 days, and the rest of the process at the treasurer's office tends to move quickly.
