Out-the-door price in New Mexico
How New Mexico works
- New Mexico charges no sales tax on a car. It charges a 4% motor vehicle excise tax on the price you pay, due when the car is titled. It is the same everywhere in the state: no city or county adds to it, and it has no minimum or cap. The dealer usually collects it and sends it to the state.
- Your trade-in comes off the price before the 4% is figured, on new and used cars, with no dollar limit. A dealer's discount comes off too, and so does a manufacturer rebate that is applied to your balance or guaranteed to you at the sale. Accessories, freight and dealer preparation are part of the price and are taxed.
- The dealer's transfer service fee (its doc fee) and any service contract are not part of the 4% tax. They carry gross receipts tax instead, at the rate where the dealer is. In 2026 that rate is 7.625% in Albuquerque, 8.1875% in Santa Fe and 8.39% in Las Cruces, and it runs from 5.25% to about 9.4% across the state. On a $400 fee the tax is about $30. The total shown here does not include that tax, because the calculator cannot add it yet.
- New Mexico does not cap the doc fee in dollars. The state's advertising rule calls it a dealer transfer service fee, and a dealer may not use the words "documentary fee" for a charge the law does not require.
- Registration is set by the car's weight and age. For a passenger car the one-year base is $33.75, $48.75 or $70, and it drops about 20% after five years. Surcharges add $4, the MVD adds a $2 service fee and a $3 title fee. A typical new 3,500-pound car pays $79 for title and one year of registration. Trucks pay by declared gross weight, from $40 to $84 for pickups up to 10,000 lbs. Fees rose 25% on July 1, 2026.
- Registering the car: a dealer that is an MVD partner, or that uses a licensed title service, can title and register the car at the sale. Otherwise it gives you a temporary permit valid up to 30 days and you go to the MVD. If no lien is placed on the car, the dealer has to tell you in writing that you can register it yourself without paying its transfer service fee.
- Electric cars and plug-in hybrids pay an added annual registration fee starting January 1, 2027: $70 and $35, rising to $80 and $40 in 2028 and $90 and $45 from 2029.
- A used car bought from a dealer is taxed on the price on the dealer's invoice. A private sale is taxed on the higher of the price or 80% of the NADA average trade-in value.

What a New Mexico advertised price has to include
For a new vehicle, New Mexico requires a dealer's advertised price to be the full cash price, but lets the dealer leave out taxes, license fees, registration and a dealer transfer service fee if the ad states the fee's amount and calls it a dealer fee. The FTC expects more: every fee the dealer charges, the transfer service fee included, belongs in the advertised price, so only government charges like the excise tax, title and registration can be added on top. That still isn't your out-the-door number; the calculator above adds the rest for your ZIP.
Federal law comes first
The FTC requires a dealer's advertised price to include every fee the dealer charges. Only charges the government requires you to pay, like tax, title and registration, can be left out. Where a state's rules let a dealer leave a fee out, the dealer still has to follow the federal rule, so the fee goes in. The FTC says a state's doc-fee rules can add disclosures, but they don't change the price that has to be advertised. Read the FTC's guidance.
New Mexico law and the FTC conflict on the dealer transfer service fee
New Mexico's rule lets a dealer leave a dealer transfer service fee out of a new-vehicle price if the ad states the fee's amount next to the price and says it is a dealer fee. The FTC expects every fee a dealer charges to be in the advertised price. Until regulators or the courts settle it, you may see New Mexico ads that leave the fee out. Ask whether a price includes it, and get the out-the-door price in writing.
What the FTC expects in the advertised price
- The dealer transfer service fee (New Mexico's doc fee; the state sets no dollar cap)
- Freight (destination) and dealer preparation charges
- Equipment the dealer puts on every car it sells, and anything else it has added to the car
- Any other fee the dealer requires
Can still be added on top
- The 4% motor vehicle excise tax
- The title fee, registration and the MVD's surcharges and service fee, and an electric car's or plug-in hybrid's added fee from 2027
- Gross receipts tax the dealer adds to its own fee or to a service contract
- Optional products you choose to buy, such as a service contract or GAP coverage
- What state law says: a new-vehicle price ad must show the full cash price. The only charges that may be left out are federal and state taxes, license fees, registration and dealer transfer service fees, and the last only if the ad states the amount close to the price and says it is a dealer imposed fee (12.2.4.21 NMAC, re-adopted effective September 9, 2026).
- Used vehicles: that exclusion list is written for new vehicles. A separate rule bars a dealer from selling any vehicle for more than its advertised price (12.2.4.20 NMAC), so a fee left out of a used-car ad is hard to square with state law too. No New Mexico ruling settles it.
- The fee's name: a dealer may not call a charge a "documentary fee" or similar term unless it is a charge actually required by law for processing documents, and it may not add charges that are plain overhead or profit under another name (12.2.4.24 NMAC).
- Cash buyers: when no lien is placed on the car, the dealer has to tell you in writing that you can register it yourself without paying its transfer service fee (12.2.4.21(A)(4) NMAC).
- Rebates and discounts: an ad that mentions a rebate has to show the full cash price and the price after the rebate, with the rebate's amount and source. An ad can't qualify a price with "with trade" or "with dealer-arranged financing" (12.2.4.16, 12.2.4.21 NMAC).

New Mexico OTD questions, answered
Does a trade-in reduce sales tax in New Mexico?
Yes — New Mexico taxes the difference: your trade-in's value is subtracted before tax is computed.
Are manufacturer rebates taxed in New Mexico?
No — rebates passed to you are treated like a cash discount and reduce the taxable amount.
Is the doc fee capped in New Mexico?
No — doc fees are uncapped in New Mexico; buyers report a typical $339.00. It's negotiable as part of your total OTD.
What does a New Mexico dealer's advertised price have to include?
Every fee the dealer charges, the transfer service fee included (the FTC's position; New Mexico lets a dealer leave that fee out of a new-vehicle price if the ad states its amount, so the two conflict). Only the excise tax, title, registration and other government charges can be added on top.
Is there a cap on New Mexico doc fees?
No. State law sets no dollar limit. A dealer has to disclose the fee, may not call it a "documentary fee" unless the law requires the charge, and has to tell a buyer with no lien in writing that the buyer can register the car and skip the fee. Ask for the amount in writing before you agree.
Do I pay sales tax on a car in New Mexico?
No. New Mexico charges a 4% motor vehicle excise tax on the price paid, less your trade-in, when the car is titled. It is the same in every city and county. The dealer's own fee and any service contract carry gross receipts tax instead.
Does the dealer register my car in New Mexico?
It can. A dealer that is an MVD partner or uses a licensed title service titles and registers the car at the sale. Otherwise you get a temporary permit valid up to 30 days and register at the MVD yourself. Apply for the title within 30 days to avoid a $20 late fee.
