Free New Mexico Vehicle Bill of Sale
New Mexico's vehicle paperwork hinges on one number most buyers overlook: the 4% Motor Vehicle Excise Tax. It's not sales tax — it's a separate MVET assessed by NM MVD at titling, calculated on your declared price (or NADA value if the price is under 80% of it). File the signed title and MVD-10002 application within 30 days of purchase — adding MVD-10009 (the state-published Bill of Sale) when the title's assignment section is incomplete — or you'll face late title penalties on top of the 4% MVET.

New Mexico Vehicle Bill of Sale — What You Need to Know
Sales Tax Details
New Mexico imposes a 4% Motor Vehicle Excise Tax (MVET) on the purchase price — this is NOT sales tax. MVET is collected by NM MVD at titling and replaces gross receipts tax for motor vehicles. The declared price is the default tax basis; if it is under 80% of NADA value, MVD uses 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 annual safety inspection. Bernalillo County (Albuquerque metro) requires a biennial emissions inspection for most gasoline cars and light trucks registered there, except vehicles in their first 4 years and vehicles 35 or more years old. Verify county requirements before titling.
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 Vehicle Sale — Step-by-Step Checklist
- If the title assignment is incomplete, complete MVD-10009 Bill of Sale with full VIN, sale price, odometer reading, and both signatures
- Have seller sign over the New Mexico title (assignment section) with odometer disclosure
- Submit MVD-10002 title application within 30 days of purchase to avoid late penalties
- Pay 4% Motor Vehicle Excise Tax on the purchase price at titling
- Provide proof of NM liability insurance and current ID before plates are issued
- Bernalillo County buyers: schedule emissions inspection if vehicle is due
Common Pitfalls
- Confusing MVET with sales tax — NM does not charge gross receipts tax on titled vehicles, only the 4% MVET
- Missing the 30-day titling window — late filing triggers penalties separate from MVET
- Writing 'gift' on bill of sale without filing the notarized gift affidavit (MVD-10018) — MVD presumes a sale whenever a vehicle is titled, so MVET is due
- Buying from a Bernalillo County seller without checking emissions status — failure means re-test fees and registration delays
Pro Tip
Treat the 4% MVET as the headline number on every NM private-party deal. Complete the title assignment (or MVD-10009 when it's incomplete), file MVD-10002 within 30 days, and document any gift exemption with the notarized MVD-10018 — without it, MVD presumes a sale and the MVET is due.
