Free New Mexico Used Car Bill of Sale
Used-car transactions in New Mexico have two gotchas: the 4% MVET (not sales tax) and the VIN inspection requirement for any vehicle arriving with an out-of-state title. Use a bill of sale to document the price, mileage, and any 'as-is' language (MVD-10009 is required when the title assignment is incomplete), then walk into MVD with the signed title, MVD-10002, and proof of insurance within 30 days. If the title is from outside NM, plan for the free VIN inspection on the same visit.

New Mexico Used Car Bill of Sale — What You Need to Know
Sales Tax Details
Used cars are subject to the 4% Motor Vehicle Excise Tax on the purchase price at titling. NM MVD compares your stated price to NADA value — if the price is under 80% of NADA trade-in or wholesale value, the tax is figured on the NADA value.
Exemption: Bona fide gifts owe no MVET with a notarized Affidavit of Gift (MVD-10018). Ask NM MVD about any other exemption before relying on it.
Inspection Requirements
No statewide safety inspection. Bernalillo County biennial emissions test required for most 1986+ gasoline vehicles. Out-of-state titles require an NM MVD VIN inspection (free, done at any field office).
Registration
Registration for this vehicle type is handled by NM MVD — not the same agency that handles cars in New Mexico. Plan for separate filings.
New Mexico Used Car Sale — Step-by-Step Checklist
- Fill out a bill of sale (MVD-10009, required if the title assignment is incomplete) with VIN, purchase price, odometer reading, and 'as-is' language
- Confirm seller signs the title assignment and odometer disclosure
- Schedule a free NM MVD VIN inspection if the title is from another state
- File MVD-10002 within 30 days and pay 4% MVET
- Document any defects on the bill of sale (MVD uses NADA value if the price is under 80% of it)
Common Pitfalls
- Forgetting the VIN inspection on out-of-state titles — MVD will refuse the application until completed
- Declaring a price under 80% of NADA value — MVD assesses the 4% MVET on the NADA value instead
- Skipping the 'as-is' clause — buyer claims later that seller warranted the vehicle
- Letting a curbstoner sell you a vehicle still in the prior owner's name (title jumping is illegal in NM)
Pro Tip
On used cars, the 4% MVET and the VIN inspection trip up most buyers. Document price honestly, schedule the inspection up front for out-of-state titles, and you'll clear MVD in one visit.
