Who Must File & Pay
You must file a WDT return and pay the tax if you meet all these criteria:
You are the registrant, owner, or operator of a motor vehicle;
The vehicle has a declared gross weight or gross vehicle weight in excess of 26,000 pounds; and
The vehicle is using highways in New Mexico.
This includes carriers operating in interstate or intrastate commerce — whether your base is in New Mexico, another state, or even outside the U.S. but you operate on New Mexico roads.
Key Points
-
The tax is based on the weight of the vehicle and the miles traveled within New Mexico.
-
You must file a quarterly weight-distance tax return and pay the tax due, even if the vehicle did not actually travel in New Mexico during the quarter.
-
Registration for a New Mexico Weight Distance Tax Electronic Permit is required annually for each vehicle.
Exceptions & Special Filing Rules
-
If your total weight-distance tax liability (or combined liability with the special fuel tax) was less than $500 in the previous year, you may be able to elect to pay annually instead of quarterly.
