Introduction
Knowing what a trip through New Mexico will cost before your truck reaches the state line makes it easier to quote loads, plan fuel stops, and avoid surprises at the port of entry. The good news is that the state trip tax follows a simple formula set in law.
This guide shows you how to estimate the cost of a New Mexico Trip Permit using your vehicle's weight and the miles you will travel in the state.
What the New Mexico Trip Permit Covers
The trip tax is set out in Section 7-15-3.1 NMSA 1978. According to the New Mexico Taxation and Revenue Department, the New Mexico Motor Transportation Police Division collects the tax and issues trip permits, and the tax is typically paid at a port of entry.
The department explains that the tax is based on the weight of the vehicle and the number of miles traveled in New Mexico. Revenue from the trip tax is deposited in the Road Fund.
In short, a New Mexico Trip Permit cost comes down to two numbers: weight and miles.
The Trip Tax Rates by Weight
Section 7-15-3.1(B) sets the per-mile rate by gross vehicle weight or combination gross vehicle weight:
| Gross Vehicle Weight | Rate Per Mile |
|---|---|
| 12,001 to 26,000 lb | 7 cents |
| 26,001 to 54,000 lb | 12 cents |
| 54,001 to 72,000 lb | 15 cents |
| Over 72,000 lb | 16 cents |
Find the row that matches your truck's weight, and you have your rate.
How to Count Your Miles
The statute says the tax applies to mileage measured from the point of entering the state to the point of destination or place of leaving the state. Only miles on New Mexico public highways count.
-
Passing through: count from your entry point to your exit point.
-
Delivering inside New Mexico: count from your entry point to your destination.
Use your planned route, not a straight line, so your mileage matches the roads you will actually drive.
A Worked Example
Say an 80,000 lb tractor-trailer crosses New Mexico on I-40, entering from Arizona and leaving into Texas, for about 370 miles in the state.
-
Step 1, check weight: 80,000 lb is over 72,000 lb, so the rate is 16 cents per mile.
-
Step 2, count miles: about 370 miles from entry to exit.
-
Step 3, multiply: 16 cents x 370 = $59.20.
That $59.20 is the estimated state trip tax for that New Mexico Trip Permit. A lighter truck on the same route at 50,000 lb would pay 12 cents x 370 = $44.40.
Prepaid Trip Permits
Section 7-15-3.1 also allows prepaid trip permits in certain cases, including custom harvesting, moving goods or passengers between New Mexico and Mexico, and vehicles that cannot state their destination or exit point when they enter the state.
-
Sold in increments of at least $50. Charges are taken against the permit at the same per-mile rates.
-
Non-refundable after one year. Any unused portion not used within one year of issue is not refunded.
-
Non-transferable. A prepaid permit cannot be transferred from one registrant, owner, or operator to another.
Common Mistakes to Avoid
-
Using empty weight instead of gross weight. The rate is based on gross vehicle weight or combination weight.
-
Counting out-of-state miles. Only New Mexico miles count toward the tax.
-
Guessing the route. A detour can add miles, so plan your entry and exit points before you go.
-
Buying more prepaid credit than you will use. Unused amounts are not refunded after one year.
