What is the New Mexico WDT Permit & Who Needs It?

A New Mexico weight distance tax (WDT) permit is an annual permit issued to New Mexico based carriers who meet the GVW requirement and motor carriers who travel in New Mexico. The permit is issued per VIN, not per fleet, and must be printed and placed in the cab of the vehicle once issued.

New Mexico WDT permits are issued immediately. The cost is $10 per truck. All miles traveled in New Mexico must be reported each quarter on the same schedule as normal IFTA taxes. Even if no miles were traveled, a return must still be filed.

Fees calculated on your return are based on the miles traveled in New Mexico, multiplied by the current quarter’s tax rate. A late fee of $5.00 is assessed for all late filings. A New Mexico permit must be renewed each year. A carrier must have all of their quarterly filings current before they are allowed to renew the permit.

All carriers who are based or frequently travel through New Mexico with a GVW over 26,000 lbs. are required to have a New Mexico WDT permit. For infrequent travelers to New Mexico, it is recommended to get a temporary weight distance permit instead of a permanent one.
