Free Colorado As-Is Bill of Sale
Colorado's lemon law (C.R.S. § 42-10-101 et seq.) covers only new vehicles purchased from licensed dealers — private party as-is sales are entirely outside its scope. Colorado UCC C.R.S. § 4-2-316 requires as-is language to be conspicuous in the written agreement to effectively exclude implied warranties of merchantability. Critically, the Colorado Consumer Protection Act (C.R.S. § 6-1-105) does NOT exempt private sellers from fraud liability — knowingly concealing a material defect in a vehicle sale is actionable even in an as-is transaction.

Colorado As-Is Bill of Sale — What You Need to Know
Sales Tax Details
Colorado's state sales/use tax rate on vehicle purchases is 2.9%. County, city, and special district taxes can significantly increase the effective rate. Buyers pay at the county DMV office at time of title transfer.
Exemption: Certain transfers between immediate family members may qualify for reduced tax treatment; consult the county clerk and recorder.
Inspection Requirements
Colorado requires emissions testing in the Denver metro 7-county area (Adams, Arapahoe, Boulder, Broomfield, Denver, Douglas, Jefferson) for most gasoline vehicles. An as-is sale does NOT exempt the vehicle from the emissions test — buyers in covered counties must pass emissions to register the vehicle. No statewide safety inspection is required for private party sales.
Colorado As-Is Sale — Step-by-Step Checklist
- Print 'THIS VEHICLE IS SOLD AS IS — NO WARRANTIES EXPRESS OR IMPLIED' in bold or all-caps prominently in the bill of sale.
- Disclose all known material defects in writing — Colorado Consumer Protection Act exposure means concealment is actionable even for private sellers.
- Complete the federal odometer disclosure on the title or a separate form for vehicles under 10 years old and under 16,000 lbs GVWR.
- If the vehicle has a salvage or rebuilt title, transfer the correct Colorado title type and disclose the salvage history in writing.
- Sign the back of the Colorado Certificate of Title over to the buyer with sale price, odometer reading, and date.
- If the vehicle is in the Denver 7-county emissions area, advise the buyer that they must pass emissions testing to register — the as-is sale does not waive this requirement.
- Provide the buyer a dated bill of sale with buyer/seller full names, addresses, VIN, year, make, model, and sale price.
- Complete the seller's portion on the title and/or use the online Title and Registration portal to report the sale.
Common Pitfalls
- Using inconspicuous as-is language — C.R.S. § 4-2-316 requires the disclaimer to be conspicuous; small-print or buried language can be voided by a court.
- Thinking the Colorado Consumer Protection Act doesn't apply to you as a private seller — courts have found that knowingly concealing a material defect in a vehicle sale can be actionable under C.R.S. § 6-1-105, making honest disclosure essential.
- Failing to disclose a salvage or rebuilt title — Colorado law requires disclosure; concealment is fraud and can result in rescission of the sale and criminal charges.
- Not warning the buyer about the emissions test requirement in the Denver 7-county area — if the seller knows the vehicle will fail emissions, failing to disclose that fact creates significant fraud exposure.
- Confusing the 2.9% state rate with the total tax — local add-ons can bring the effective rate to 8–10% in some Denver metro areas; buyers should confirm total tax with the county DMV office.
Pro Tip
Colorado's as-is framework is functional for private sellers, but the Consumer Protection Act's potential applicability to private individuals makes written disclosure of known defects non-optional. Handle the emissions test disclosure proactively for Denver-area sales, and ensure your as-is language is bold and prominent.
