New Mexico Car Sales Tax Calculator
New Mexico's vehicle sales/use tax depends on where you register and other factors, so it isn't a single statewide figure. Use the calculator and the official New Mexico Motor Vehicle Division (MVD) source below to confirm what applies to your purchase.
Estimate your New Mexico car sales tax
Enter the vehicle price. If New Mexico gives a trade-in tax credit, add your trade-in value to reduce the taxable amount.
State rate only. Many New Mexico counties and cities add a local sales tax on top, so your actual total may be higher. Trade-in credit rules vary — confirm eligibility with the official source below.

What this estimate excludes
- Local and district taxes. County, city, and transit taxes are added on top of the New Mexico state rate.
- Title, registration, and plate fees. These are separate from sales tax — use the New Mexico registration and title-transfer calculators for those.
- Dealer documentation fees. A dealer “doc fee” is charged on top and is often itself taxable.

Frequently asked questions
How much is sales tax on a car in New Mexico?
New Mexico does not reduce to one statewide vehicle tax rate — it varies by locality and purchase type. Check the official New Mexico Motor Vehicle Division (MVD) source for the rate that applies to you.
Do I pay sales tax when buying a used car from a private seller in New Mexico?
In most states, sales or use tax on a private-party vehicle purchase is collected when you title and register the car, not at the point of sale. The rate is generally the same as a dealer sale. Confirm the private-sale rules with New Mexico Motor Vehicle Division (MVD).
Does New Mexico give a sales tax credit for a trade-in?
Most states tax only the difference between the vehicle price and your trade-in value, which lowers the tax you owe. A handful of states tax the full price with no trade-in credit. Verify New Mexico's treatment before you rely on the estimate above.
Are there local or county car sales taxes in New Mexico?
Often, yes. The rate shown here is the New Mexico state rate only; many counties, cities, and transit districts add a local sales tax on vehicle purchases, so your combined rate can be higher. New Mexico Motor Vehicle Division (MVD) publishes the official combined rates.
