Your New Mexico car post-sale checklist
- 1
Keep your signed New Mexico bill of sale
This is your proof that you sold the car on the sale date. If the buyer gets a ticket, is in an accident, or fails to transfer the title within 90 days from the sale date, the New Mexico bill of sale shields you from liability. Keep both your copy and a scan for at least 5 years.
- 2
File a release of liability with New Mexico DMV
Most New Mexico sellers file this online through New Mexico DMV within 5 days of the sale. Filing removes you from records as the registered owner so any post-sale tickets, tolls, or accidents become the buyer's responsibility, not yours. New Mexico requires the buyer to title the car within 90 days — your release filing protects you if the buyer misses that deadline.
- 3
Cancel or transfer your auto insurance
Contact your insurer the same day you hand over the keys. New Mexico does not require you to maintain insurance on a vehicle you no longer own, but you must not cancel before the sale is complete. If you are replacing the car with another, transfer the policy instead — many insurers offer a short grace period to bind coverage on the new vehicle.
- 4
Remove your license plates
In New Mexico, plates go with the seller — not with the car. Remove the plate(s) before the buyer drives or rides away. You can return them to New Mexico DMV or transfer them to your next vehicle.
- 5
Verify the 90-day title transfer window
New Mexico requires the buyer to retitle the car at New Mexico DMV within 90 days of the sale date. If you have not received confirmation that the title has been transferred by day 95, contact New Mexico DMV with your bill of sale and release-of-liability filing number to confirm the change of ownership.
- 6
Confirm your New Mexico tax obligations (seller's side)
New Mexico charges 4% sales/use tax on private-party car sales — the buyer pays this at New Mexico DMV when titling. 4% motor vehicle excise tax applies to all vehicle sales. Sellers generally do not owe New Mexico sales tax, but if the car sold for more than your original purchase price you may owe federal capital gains tax. Consult a tax advisor.
- 7
Watch for liens or loan payoff confirmation
If you had a loan on the car, confirm the lender received the buyer's payoff and has released the lien on the New Mexico title before you deliver the title. New Mexico uses MVD Title (lien section) as the lien release form — your lender will file this with New Mexico DMV to clear the title record.
New Mexico lien release procedure
- Lienholder completes the lien release section on the back of the existing New Mexico title.
- Owner submits the released title and title application at a New Mexico MVD office.
- Pay the title fee and receive a clean New Mexico title.
Frequently Asked Questions — New Mexico
How long do I have to file a release of liability in New Mexico?▾

What is the New Mexico title transfer deadline for a car?▾

Do I owe New Mexico sales tax on the car I just sold?▾
New Mexico charges 4% sales/use tax on private-party car sales. 4% motor vehicle excise tax applies to all vehicle sales. The buyer typically pays this at New Mexico DMV when titling — sellers generally owe no New Mexico sales tax on the proceeds. You may owe federal capital gains if you sold for more than the original purchase price.
Does New Mexico require a notary on the car bill of sale?▾
No. New Mexico does not require notarization for a private car bill of sale. A signed bill of sale with both parties' full names, addresses, signatures, and the date is sufficient for New Mexico DMV.
How does the buyer register the car in New Mexico?▾
The buyer brings the signed bill of sale and endorsed title to New Mexico DMV, pays the title fee (~$5) plus 4% sales/use tax, and receives a new New Mexico title in their name. Transfer must be completed within 90 days of the sale date.
What if the buyer hasn't transferred the title yet?▾
In most states this is the buyer's responsibility, not yours. Filing a release of liability with your state DMV is the seller-side protection — it removes you from records as the registered owner so any post-sale tickets, accidents, or tolls fall on the buyer regardless of when the title is actually transferred.
Do I need to keep the bill of sale after the sale is complete?▾
Yes — keep your signed bill of sale for at least 5 years. If a parking ticket, toll, or accident occurs after the sale but before the buyer transfers the title, the bill of sale is your proof that the car was sold on the sale date. Store a scan and the original.
