1. Who Needs a Weight Distance Tax Permit

You must have a Weight Distance Tax Permit in New Mexico if your commercial vehicle:

  • Has a gross vehicle weight over 26,000 lbs, or

  • Is part of a fleet that exceeds the legal weight limits, or

  • Operates interstate or intrastate routes on public highways.

Smaller vehicles under 26,000 lbs typically do not require this permit.

2. How the Tax Works

The tax is calculated based on:

  • Distance traveled in New Mexico (miles)

  • Weight of the vehicle (gross vehicle weight)

  • Type of vehicle (e.g., truck, trailer, combination)

Example: A 50,000 lbs truck traveling 1,000 miles in New Mexico will pay higher WDT fees than a 30,000 lbs truck for the same distance.
