New Mexico car excise tax and MVD fees

The excise tax replaces the sales tax

Instead of a sales tax with local add-ons, the Taxation and Revenue Department collects a single 4% motor vehicle excise tax when the title is issued, whether the seller is a dealer, a neighbor or an out-of-state lot. The base is the price paid minus any trade-in allowance. A private seller cannot dodge it with a low bill of sale: if the declared price is under 80% of the N.A.D.A. average trade-in or wholesale value, the department taxes the book value instead. Wait more than 90 days to title the car and a 50% penalty is added, which turns the 4% into 6%. A genuine gift is exempt with a notarized affidavit.

Registration after the July 2026 increase

Lawmakers raised passenger registration fees by 25% on July 1, 2026, the first change since 2004. Under section 66-6-2, the fee now depends on two things: the factory shipping weight and whether the car has had five years of registration. A car of 2,000 lb or less pays $33.75, one of 2,001 to 3,000 lb pays $48.75 and anything heavier pays $70. After five years those amounts drop to $26.25, $38.75 and $56.25. A typical used sedan bought privately for $9,000 therefore costs $425 to title and register outside Bernalillo County. You may register for two years at twice the yearly fee, and renewing online or by phone takes 5% off the registration fee.

Electric cars, from 2027

New Mexico had no surcharge on electric cars until the 2026 transportation law. The new fee starts on January 1, 2027 at $70 a year for a battery electric car and $35 for a plug-in hybrid, then climbs to $80 and $40 in 2028 and $90 and $45 from 2029. Ordinary hybrids are not affected. Neighboring Arizona takes a different route, taxing the car's value every year instead.

What sets New Mexico apart

• New Mexico charges no sales tax on a car: it levies a 4% motor vehicle excise tax on the price paid, due when the title is applied for (New Mexico Taxation and Revenue Department).
• A trade-in allowance may be deducted from the price before the 4% is applied (NMSA 1978 § 7-14-4).
• On a private sale, the excise tax uses the N.A.D.A. value when the declared price is below 80% of the N.A.D.A. average trade-in or wholesale value (New Mexico Taxation and Revenue Department).
• Titling more than 90 days after the transfer adds a 50% penalty to the excise tax, which raises the effective rate to 6% (New Mexico Taxation and Revenue Department).
• Passenger registration fees rose on July 1, 2026, the first increase since 2004: $70 a year for a car over 3,000 lb in its first five years, $56.25 after that (NMSA 1978 § 66-6-2).
• A car of 2,000 lb or less pays $33.75 a year, and one of 2,001 to 3,000 lb pays $48.75, falling to $26.25 and $38.75 after five years of registration (NMSA 1978 § 66-6-2).
• Every registration also carries a $1.50 tire recycling fee, a $2 additional fee and a 50-cent beautification fee (NMSA 1978 §§ 66-6-6.1 and 66-6-6.2).
• From January 1, 2027, electric cars pay an extra $70 a year and plug-in hybrids $35, rising to $90 and $45 from 2029 (NMSA 1978 § 66-6-6.4).
• Cars can be registered for one year or two, and the two-year fee is twice the yearly fee (NMSA 1978 § 66-3-20.1).
• Cars registered in Albuquerque-Bernalillo County need an Air Care emissions test; fully electric cars are exempt and new cars are exempt for 4 years (City of Albuquerque).

What the New Mexico calculation cannot know

• On a private sale the excise tax uses the N.A.D.A. value when the declared price is below 80% of the N.A.D.A. average trade-in or wholesale value; the form does not ask the book value, so the engine taxes the price.
• The reduced registration fee applies after five years of registration counted from the date the vehicle was first registered; the engine counts the five years from the model year (age 5 and over), which can differ by up to a year.
• Albuquerque-Bernalillo County Air Care stations set and post their own emissions test price (the city says it is usually about $30 plus tax); the test is shown without an amount.
• The New Mexico MVD website could not be opened from our location for this release; every MVD figure was read in the official statutes (NMSA 1978 on NMOneSource, the New Mexico Compilation Commission) and in the Taxation and Revenue Department's pages.
• No legal cap on dealer documentation fees was found in the Motor Vehicle Code or the Motor Vehicle Excise Tax Act; type the dealer's fee. Whether that fee bears gross receipts tax is not computed.
• Optional costs are left out: the 5% discount for renewing online or by phone, the save our children's sight check-off and special plates.
