To transfer a title in a New Mexico private sale, the seller signs over the title with the sale price, date and odometer reading filled in, pulls their license plate off the car, and you take that title to the MVD or an MVD partner office within 30 days to apply for a new title and registration. You pay the 4 percent motor vehicle excise tax at that visit, and if the car carries an out-of-state title, it needs a VIN inspection first. Miss 30 days and there is a $20 late transfer fee; wait past 90 days and the excise tax jumps by half.
I went through the MVD's vehicle titles page, the buying-a-vehicle checklist and chapters 4 through 6 of the MVD Vehicle Procedures Manual on October 16, 2026. Some manual sections date back to 2017, and registration fees depend on the vehicle, so the clerk's screen is the final word.
What the seller hands you, and what you check before paying
The MVD's buying page puts it simply: make sure the seller has signed the right section of the title, filled in your name as purchaser, and completed the odometer, purchase date and selling price fields. Then both of you sign the odometer statement agreeing on the mileage. The title is the primary ownership document, and per chapter 4 of the procedures manual, photocopies are not accepted for any title transaction. If the seller only has a copy, you do not have a deal yet.
When the assignment area on the back of the title is incomplete or full, the seller fills out the state's MVD-10009 Bill of Sale instead. It has to list year, make, VIN, sale price and both parties' names, addresses and signatures. Honestly, I would ask for one even when the title has room. It pins down when the 30-day clock started.
New Mexico runs a plate-to-owner system, so the seller removes the plate at the sale and has 30 days to move it to another vehicle of the same class or turn it in. That means you drive away without plates. Plan for that before you show up with cash; the MVD's own title page says a car with only a title cannot be driven until it is registered, plated and insured.
The 30-day deadline and the 90-day excise penalty
Chapter 5 of the manual, citing section 66-3-103(B), says vehicles must be titled and registered within 30 days, and the clock starts on the date of assignment on the title or bill of sale, whichever is earlier. The fees and penalties chapter sets the late transfer fee at $20 once you pass 30 calendar days.
The bigger hit is the excise tax penalty. According to the MVD vehicle titles page, a New Mexico resident who accepts a transfer and fails to apply for title within 90 days owes a 50 percent penalty on top of the tax, which the MVD itself describes as turning a 4 percent tax into 6 percent. On a $12,000 car that is the difference between $480 and $720. Not worth stalling over.
How the 4 percent excise tax is figured in a private sale
The motor vehicle excise tax is 4 percent of the price paid, minus any trade-in credit, and it is due when you apply for the title. The MVD presumes every titling is a sale. For non-dealer sales, though, there is a floor: if the declared price is lower than 80 percent of the N.A.D.A. average trade-in or wholesale value, the MVD taxes the N.A.D.A. figure instead. So writing $500 on the bill of sale for a car worth $9,000 does not work, and it is a bad idea anyway.
A genuine gift owes no excise tax, but both donor and recipient have to sign a notarized Affidavit of Gift (MVD-10018) under penalty of perjury. If you bought the car out of state and paid another state's sales or similar tax, that amount can be credited against the New Mexico excise tax. For how this compares with sales-tax states, see our used car sales tax breakdown.
Out-of-state titles: VIN inspection and an NCIC check
If the car is titled in another state, you take it to the MVD for a VIN inspection or have a certified VIN inspector do it. Chapter 4 says the inspection form (MVD-10861) is good for 90 days from the inspection date, and if the inspector sees signs of tampering with the VIN plate, the inspection stops and law enforcement gets called. Our VIN verification for title transfer guide shows where to look for those numbers yourself before you buy.
Separately, the MVD titling system runs every VIN against the FBI's NCIC database, and that check has to come back clear before a title is issued. A stolen car tends to surface right there, at the counter, after you have already paid the seller. Check the brand history on NMVTIS before money moves, and if the title mentions salvage or rebuilt, read our New Mexico salvage and rebuilt title rules first.
Odometer disclosure, and the age cutoff
The manual says an odometer statement is required on all New Mexico motor vehicle title transactions except off-highway vehicles. Federal rules set the age exemption: under 49 CFR 580.17, a model year 2010 or older car is now exempt, while 2011 and newer cars need a disclosure until they are 20 years old. More on reading those forms in our odometer disclosure statement post.
Pull your own history report
Seller-supplied printouts are easy to fake, and we have seen edited PDFs with the accident section simply missing. Run the VIN yourself; our CARFAX for private-party sales notes cover what to look for. CarVins is a licensed CARFAX and AutoCheck reseller, not affiliated with CARFAX, AutoCheck or Experian. This week a guest report runs about $5.50, members pay around $4.50, and the two-report bundle is near $6.75, compared with roughly $39.99 to $44.99 buying direct. Those can shift, so the checkout page has the real number.
