## Who Needs a New Mexico Weight Distance Permit?

New Mexico's highway use tax for heavy trucks is the Weight Distance Tax, charged per mile for using the state's highways, with a weight distance permit for each truck. It applies to vehicles with a declared gross weight over 26,000 pounds on New Mexico highways, whether the carrier is based in the state or passing through on I-40, I-10 or I-25. Each qualifying vehicle needs a weight distance tax permit, a state registration renewed annually, or a temporary trip permit for a carrier that enters rarely. The tax is separate from IFTA, which New Mexico also collects, and from IRP.

## How Is the NM Weight Distance Tax Rate Calculated?

Unlike Kentucky's flat rate, New Mexico's climbs with the vehicle's declared weight through a schedule of weight classes, so an 80,000-pound combination pays more per mile than a 30,000-pound straight truck. Carriers that haul loaded one way and return empty can register for the one-way haul rate, a separate and lower rate schedule, if the vehicle is customarily used for one-way hauls and runs empty for 45 percent or more of its annual miles. Declared weight counts twice: it sets your rate, and officers check it against the scale.

## How Do You File the Weight Distance Tax Return?

You file returns quarterly with the Motor Vehicle Division through MVD Online Services, due at the end of the month after the quarter (a carrier that owed less than $500 can file annually), reporting New Mexico miles per vehicle at its weight class. A permit holder with no New Mexico miles in a quarter still files a return. Keep records for audit; the auditor compares your weight distance miles with the New Mexico line on your IFTA return.

## Getting the New Mexico Miles Right

The return needs one figure: New Mexico miles per vehicle per quarter. Telematics produces it from continuously logged position, in the same jurisdiction report that feeds IFTA, so carriers running I-40 and I-10 file matching numbers. For fleets that touch New Mexico only on long-haul runs, the report also shows whether an annual permit is worth holding or trip permits cost less. High Point GPS sets up jurisdiction reporting for carriers whose southwestern runs cross the state.

## FAQ

### Who pays New Mexico Weight Distance Tax?

Any carrier operating a vehicle with a declared gross weight over 26,000 pounds on New Mexico highways pays it, based in New Mexico or not. Each qualifying vehicle needs an annual weight distance tax permit, or a temporary permit for an occasional trip.

### How is the New Mexico highway use tax calculated?

You multiply each vehicle's New Mexico miles by a rate that rises with its declared weight class. Carriers that haul loaded one way and return empty can register for the lower one-way haul rate if the vehicle runs empty for 45 percent or more of its annual miles.

### Is New Mexico weight distance tax filed with IFTA?

No. Weight distance tax has its own quarterly return, filed with the New Mexico Motor Vehicle Division through MVD Online Services. Both returns use New Mexico miles, though, and an audit compares the weight distance miles with the New Mexico line of your IFTA return.

### Do I need a permit for one trip?

Yes. For a single trip you need a temporary weight distance permit. If you expect to come back regularly, the annual permit makes more sense, and a telematics jurisdiction report on your past New Mexico miles shows which option costs less.

### What records are needed?

Keep trip-level New Mexico mileage for each vehicle for the quarter, and make sure it reconciles with your IFTA return. Hold those records for audit. A GPS or ELD jurisdiction report gives you that mileage per vehicle from logged position.
