Bill of sale guide

Colorado vehicle bill of sale

Colorado requires a bill of sale only in some cases, explained below. No notary is needed. Here's what to put on one and how to sell a car in Colorado, from signing the title to handing over the keys.

Make your bill of sale

Fill in each section, then print it on letter-size paper or save it as a PDF. No account needed.

What are you selling?

Colorado has an official bill of sale form: Motor Vehicle Bill of Sale (DR 2173). Check whether your motor vehicle office wants that form. Open the official form

Colorado doesn't require a notary for a bill of sale. You can still add a notary block.

Seller

Add everyone named on the title as an owner. If their names are joined by "and", each one signs.

Buyer
Vehicle

It's on the title and registration, at the base of the windshield on the driver's side, and on the label in the driver's door jamb.

Odometer

Whole miles only. Federal rules say no tenths.

The seller states that this reading:

Choose the one that's true. Mechanical limits is for an odometer that has rolled past its highest number.

This doesn't replace the odometer section on the title. If the title has one, fill it in too.

Sale

Colorado buyers who drive home without plates under the state's 36-hour rule need the time and date of sale on a bill of sale you both sign.

Type of transfer

Print two copies. You and the buyer sign both, and each keeps one.

Nothing you type is saved or sent anywhere. The VIN lookup sends only the VIN.

This is general information, not legal advice. Check your state's requirements before you sign.

Do you need a bill of sale in Colorado?

Fill in the free Colorado bill of sale on this page and print it.

If the title is filled out correctly, including the sale price and date, a bill of sale is not needed for the title transfer. The DMV calls a bill of sale best practice and requires one if the sale price is not on the title. A secure version of the bill of sale, sold through vendors the DMV lists, can also carry the odometer disclosure. A buyer driving home without plates under the 36-hour rule must carry a bill of sale signed by both parties that shows the time and date of sale.

Use the official form if you prefer it: Motor Vehicle Bill of Sale (DR 2173).

What a Colorado bill of sale must include

Colorado lists these items:

  • Purchase price
  • Date of sale (and time of sale if the buyer will use the 36-hour rule)
  • VIN
  • Year, make and model
  • Buyer's and seller's names
  • Buyer's and seller's signatures

How to sell a car in Colorado

  1. Sign and print your name in the Seller section on the back of the Colorado title, exactly as printed on the front.
  2. Make sure every owner named on the front of the title signs as a seller.
  3. Enter the exact odometer reading, purchase price and date of sale on the title.
  4. Give the buyer the signed title and a bill of sale (DR 2173 or a written equivalent).
  5. If the vehicle is more than 7 model years old and the buyer lives in an emissions area, give the buyer a new passing emissions certificate.
  6. Remove your license plates before the buyer drives away.
  7. Report the sale within 5 days with Report Release of Liability on myDMV or at your county motor vehicle office.

Where to sign a Colorado title

Back of the Colorado title, in the Assignment of Owner section. The seller prints their name and signs in the Seller area, enters the odometer reading and checks actual mileage, not actual mileage, or mileage in excess of mechanical limits, and enters the purchase price and date of sale. All owners named on the front must sign. If the printed name does not match the front of the title, a Statement of One and the Same (DR 2421) is required. A first initial and last name is not acceptable. The title signature does not need a notary in Colorado.

Reporting the sale in Colorado

Optional. Colorado doesn't require it, but you can report the sale (Report Release of Liability) within 5 days of the sale. You can file it online. The DMV says it removes the seller from liability for the buyer's later actions with the vehicle.

What happens to your license plates when you sell a car in Colorado?

Plates are tied to the registered owner, not the vehicle. Remove them before the buyer drives away. Under Senate Bill 21-069, regular plates expire when ownership transfers. Return them to a county motor vehicle office or recycle them with a recycling service that takes metal. Personalized plates may be moved to your next vehicle through your county office.

Inspection, odometer and sales tax in Colorado

Inspection. If the vehicle is more than 7 model years old and the buyer lives in an emissions testing area, the seller must give the buyer a new passing emissions certificate. Testing areas are Boulder, Broomfield, Denver, Douglas and Jefferson counties, and parts of Adams, Arapahoe, Larimer and Weld counties.

Odometer disclosure. Required on every transfer for model year 2011 and newer vehicles for their first 20 years. Exempt: vehicles 20 years or older, vehicles with a gross weight rating over 16,000 lbs, and trailers. The seller enters the mileage on the title or on a DR 2173 bill of sale and checks actual mileage, not actual mileage, or mileage in excess of mechanical limits.

Sales tax. A private seller who is not a licensed retailer generally does not collect sales tax. The buyer generally pays the 2.9% state sales tax and any local sales or use taxes to the county clerk at registration. The buyer also pays Specific Ownership Tax as part of registration.
