Short answer: New Mexico taxes the owners, operators and registrants of commercial vehicles with a declared gross weight over 26,000 pounds for the miles they run on New Mexico roads, intrastate and interstate alike (MVD, Weight Distance; Section 7-15A-3 NMSA 1978). You register the company and apply every year for a Weight Distance Tax Electronic Permit for each vehicle through the state portal TAP at tap.state.nm.us. You file a return quarterly, due April 30, July 31, October 31 and January 31, and you file even for a quarter with no New Mexico miles at all. The rate depends on declared weight and it went up 35 percent on July 1, 2026: from 14.86 mills per mile at 26,001 pounds to 59.10 mills at 78,001 pounds and over, which is 1.486 to 5.91 cents per mile.
The part that surprises carriers from the East Coast is that IRP plates and IFTA decals do not cover this. A truck can be perfectly apportioned, perfectly fueled up, and still be assessed at the scale house on I-40 because there is no New Mexico weight distance account behind the truck. This guide covers that account, that permit and that return. Forming the company and the federal layer are on the New Mexico start-up page.
The MVD page states it in one sentence: New Mexico imposes a weight-distance tax on owners, operators and registrants of intra and interstate commercial vehicles with a declared gross vehicle weight in excess of 26,000 pounds, and the tax is based on vehicle weight and miles traveled on New Mexico roads. Three consequences follow that people miss.
Over 26,000 pounds declared gross weight, and the wording is not identical everywhere. MVD and the paper return say in excess of 26,000 pounds, the Taxation and Revenue Department says over 26,000 pounds, and the regulation says the opposite: 3.12.6.2 NMAC applies the part to vehicles with a declared gross weight of 26,000 pounds or more. The rate schedule settles the disputed point on its own: the first class starts at 26,001 to 28,000, so a truck declared at exactly 26,000 sits below the first class.
What counts is the declared weight, not what is on the truck today. The instructions to the paper return define the weight class as the highest gross vehicle weight or combined gross vehicle weight declared for registration purposes, and add the warning that it is unlawful to operate on New Mexico highways at a gross vehicle weight higher than the declared one (Form MVD-10964 instructions). Combined weight is the phrase that answers the trailer question: the trailer is already inside the number you declared for the tractor.
One year, one vehicle, one permit. MVD: companies must register and apply each year for a New Mexico Weight Distance Tax Electronic Permit for each vehicle. The permit is bought through TAP, and the state's own answer says you do not have to log in to buy it: you need the FEIN, the Weight Distance Tax number, the USDOT number, a payment method and an email address, and an existing WDT account with the department. Changing or inactivating a permit is done inside TAP, on the Weight Distance Tax account summary page, through the View or Update permits link.
Two details decide whether the year goes smoothly. A vehicle titled in New Mexico that runs intrastate gets a weight-distance plate; the same vehicle running interstate gets an IRP plate. And if a quarterly return is missing, the system will not process the e-permit, which is how an unfiled zero return in April becomes a truck that cannot be permitted in January.

The rate. Senate Bill 2 of the 2026 regular session was signed by the governor on February 5, 2026 and chaptered as Chapter 4. Section 1 of the act rewrites Section 7-15A-6 NMSA 1978, the rate schedule for motor vehicles other than buses, and Section 7 of the act sets the effective date of that section as July 1, 2026.
NMDOT put the size of the change in a press release dated June 30, 2026: passenger vehicle registration fees rose 25 percent and the weight-distance tax rose 35 percent, the first adjustment to either in more than two decades, with an estimated $70 million a year going to the State Road Fund. In the top class the number moved from 43.78 mills to 59.10 mills per mile, and in the first class from 11.01 to 14.86.
Miles times a rate set by weight. MVD describes the mill rate as the cents per mile paid for the weight distance tax, depending on the weight of the vehicle and on whether it is used for one-way or two-way hauling. The schedule is stated in mills, and one mill is a tenth of a cent, so 59.10 mills is 5.91 cents, or $0.0591 per mile.
The return does the arithmetic in four columns: weight distance miles, minus port of entry miles already paid, equals net weight distance miles, times the mill rate, equals tax due. One weight class per row, and a separate row when you are reporting a one-way haul rate and a full haul rate for the same class; the form says plainly not to combine one-way and full haul miles on the same line. A truck declared at 80,000 pounds that runs 400 New Mexico miles in a quarter owes 400 times $0.0591, that is $23.64. On the old table the same run was $17.51.

Carriers that run loaded one way and empty back. Subsection B of Section 7-15A-6 sets the reduced tax at two thirds of the full computation, and it attaches three conditions: the vehicle is customarily used for one-way haul; 45 percent or more of the miles it travels in a registration year are traveled empty of all load; and the registrant has made a sworn application to the department to be classified that way for the registration year, with the vehicle actually classified.
The status is claimed at registration or reregistration, for vehicles the registrant can reasonably expect to run 45 percent or more of New Mexico miles empty (3.12.6.8 to 3.12.6.11 NMAC). It is not a standing discount. In any reporting period where the vehicle did not reach 45 percent empty miles, the tax is due at the full rate. And if a vehicle fails the test in at least three reporting periods of a registration year (3.12.6.9 NMAC), it cannot be identified as a one-way hauler for the next year, although an amended return can recover an overpayment when the miles did in fact qualify. Empty miles mean miles run with no load whatsoever, and the rule expects per-vehicle mileage records split into empty and loaded, plus itineraries showing origins, destinations and the roads travelled.
Four dates, published by the Taxation and Revenue Department: April 30 for January 1 through March 31, July 31 for the second quarter, October 31 for the third, and January 31 for October 1 through December 31. Certain taxpayers may elect to pay annually instead. The right comes from Section 7-15A-9 NMSA 1978, named in 3.12.6.10 NMAC, but the qualifying threshold is not published on the state pages, so confirm eligibility with the Commercial Vehicle Bureau at 1-888-683-4636 prompt 6 before you assume it.
Filing is done in TAP, single or bulk. Under 3.1.4.18 NMAC, if the return is due after August 1, 2010 and you pay tax for two or more trucks, you must file electronically, and once you are required to file electronically you may not go back to mail. Paper filers use Form MVD-10964, mailed to the Motor Vehicle Division, P.O. Box 5188, Santa Fe, NM 87504-5188. Send the confirmation of electronic filing with the payment: the department warns that payments without confirmation or a tax identification number may not be applied to the account, and penalty and interest can be assessed on the gap.
| Obligation | How often | Form or system | What a miss costs |
|---|---|---|---|
| Weight Distance Tax Electronic Permit | Every year, per vehicle | TAP | Running without a permit; trip fees assessed at a port of entry |
| Weight distance tax return | Every quarter, including zero quarters | TAP single or bulk; paper MVD-10964 | Penalty 2 percent per month to 20 percent, daily interest, and the e-permit is blocked |
| Electronic filing from two vehicles | With every return | TAP, 3.1.4.18 NMAC | A mailed return is not an accepted filing method |
| IFTA return | Every quarter | TAP | Penalty and interest under IFTA rules |
| IRP renewal | Every year | MVD Commercial Vehicle Bureau | No valid cab card in the truck |
| Form 2290 (HVUT) | Every year, at 55,000 pounds and up | IRS | Nothing to show MVD at registration |
| Address change | When it happens | MVD CVB and TRD | State notices count as delivered to the old address on file |
| Closing the account | Once | Letter to the Commercial Vehicle Bureau, fax 505-476-1571 | Returns and liabilities stay open against the company |
Yes. The department states it without conditions: even if a carrier has not traveled through New Mexico, the carrier must file a return. A quarter where the truck never crossed the state line is a two-minute filing in TAP, and skipping it starts a chain that is much more expensive than the tax would have been.
The chain is mechanical. No return means penalty accrual on any balance and, separately, the system will not process the electronic permit while a quarterly return is missing. So a skipped zero return in April is discovered in January, when the renewal fails and the trucks that were supposed to leave on Monday cannot be permitted. The same logic applies to the rest of the state file: this is the pattern covered for other states in the Oregon weight-mile tax guide, where a missed zero report costs the account rather than the tax.
New Mexico publishes both numbers. Penalty is 2 percent per month or partial month, to a maximum of 20 percent of the unpaid principal of tax due. Interest accrues daily on the unpaid principal, the rate changes quarterly, and since January 1, 2008 it has been the rate the Internal Revenue Code sets for individual income tax. The department also states that interest by law cannot be waived (TRD penalty and interest rates). The last period published in that table at the time of writing runs to March 31, 2026 at 7 percent a year, so look up the current quarter rather than assuming. Liabilities under IFTA can carry a different interest rate, calculated monthly. The department's own formula is short: tax due, times the daily rate for the quarter, times the number of days late. On a $300 balance paid 15 days late at 7 percent a year that is under a dollar of interest, while the 2 percent penalty on the same $300 is $6 for the first month alone. Penalty, not interest, is the number that hurts.
There is a route for the occasional run: trip tax. Commercial vehicles not registered or licensed in New Mexico that carry passengers or property for hire or for resale pay a trip tax in lieu of registration or use fees under Section 7-15-3.1 NMSA 1978 (TRD, Trip Tax). It is collected by the Motor Transportation Police Division, typically at a port of entry, and prepaid permits may be authorized in increments of no less than $50.
The per-mile numbers come from MVD's own answer for carriers without an IRP cab card listing New Mexico or a New Mexico Tax Identification Permit. Compare them with the table above before deciding to skip the account: at 80,000 pounds the trip tax is about 2.7 times the weight distance rate.
| What you pay | How much | Where |
|---|---|---|
| Trip tax, 0 to 26,000 pounds | 7 cents per New Mexico mile | Port of entry |
| Trip tax, 26,001 to 54,000 pounds | 12 cents per mile | Port of entry |
| Trip tax, 54,001 to 72,000 pounds | 15 cents per mile | Port of entry |
| Trip tax, over 72,000 pounds | 16 cents per mile | Port of entry |
| Prepaid trip permit | Increments of no less than $50 | As authorized by MTPD |
| Fuel tax without an IFTA license and decals | 5 cents per mile, on a consumption basis | Port of entry |
| Temporary special fuel permit | $5.00, 48 hours, valid for one trip | Port of entry |
| Miles already paid at a port of entry | Deducted from the quarterly return | Column C of Form MVD-10964 |
Stopping is not optional. MVD states that state law requires commercial motor carrier vehicles to enter, leave and travel through New Mexico on designated highways and to stop at every operating port of entry for manifesting and clearance stickers. What happens inside is credential checking, oversize and overweight work, driver and vehicle inspections, and the assessment and collection of taxes and fees. Fuel permits and trip permits are issued there. The stop rule is wider than the tax: MVD's definition of a commercial motor vehicle for this purpose starts at 10,001 pounds for interstate operation and 26,001 for intrastate, so a hotshot rig well under the weight distance threshold still pulls in.
The New Mexico State Police list shows thirteen sites at the time of writing, with 24-hour ports on the two lanes East Coast carriers actually use: Gallup on I-40 eastbound at mile marker 12 and San Jon on I-40 westbound at mile marker 356, Lordsburg on I-10 eastbound at mile marker 23 and Anthony on I-10 westbound at mile marker 159. For an out-of-state carrier the officer expects a current IRP registration from the base state listing New Mexico or a valid trip permit, an IFTA license and decals, a USDOT number, and a New Mexico Tax Identification Permit. If the card is not presented, trip fees are assessed on the spot.
Four obligations, none of which substitutes for another. IRP is the registration: fees go to the base jurisdiction and are distributed by the distance run in each member state, and only one plate and one cab card are issued per vehicle. The mechanics are in the step-by-step IRP guide. IFTA is the fuel tax; New Mexico runs it through the same Commercial Vehicle Bureau, and in this state diesel is the only fuel treated as special fuel on an IFTA return. The quarterly mechanics are in the IFTA filing walkthrough. Form 2290 is the federal heavy vehicle use tax at 55,000 pounds and up, paid to the IRS, with the stamped Schedule 1 shown to MVD at registration: see the 2290 deadline guide. Weight distance tax is the state's own charge for the miles. If you want the four side by side, that comparison is IRP vs IFTA vs NY HUT vs 2290. New York, Oregon and Kentucky charge their own mileage taxes on the same trucks, each with its own thresholds and its own filing calendar.
We open the weight distance account and the electronic permit for every truck, set up IRP and IFTA, and file the quarterly returns, including the zero ones, so a missing return never blocks a permit renewal in January. Permits from $200. Opening a company from scratch: Authority Bundle, $499. Ongoing WDT filing, IRP work and trailer registration are handled end to end, pricing on request. Russian and English.

It is a state tax on the use of New Mexico highways by commercial vehicles with a declared gross weight over 26,000 pounds, owed by registrants, owners and operators under Section 7-15A-3 NMSA 1978. The base is weight and miles: each vehicle has a weight class, each class has a mill rate, and you pay that rate on every New Mexico mile. It applies whether the truck is registered in New Mexico or not, and whether the work is intrastate or interstate.
Yes, if the declared gross weight is over 26,000 pounds and the truck uses New Mexico roads. MVD requires companies to register and apply each year for a Weight Distance Tax Electronic Permit for each vehicle, bought through TAP with your FEIN, WDT number, USDOT number, payment method and email. The alternative for a genuinely occasional run is trip tax at the port of entry, which is several times more expensive per mile.
From $0.01486 per mile at 26,001 to 28,000 pounds up to $0.05910 per mile at 78,001 pounds and over, under the schedule effective July 1, 2026. Those are the full rates; a vehicle classified as a one-way hauler pays two thirds of them. The tax went up 35 percent on July 1, 2026, the first change since 2004, so any calculator or form still showing 0.01101 and 0.04378 is out of date.
April 30 for the quarter January 1 through March 31, July 31 for April 1 through June 30, October 31 for July 1 through September 30, and January 31 for October 1 through December 31. Certain taxpayers may elect to pay annually under Section 7-15A-9 NMSA 1978, but the state pages do not publish the qualifying threshold, so confirm with the Commercial Vehicle Bureau before relying on it. Returns are filed in TAP, and from two trucks up electronic filing is mandatory.
Yes. The department states that even if a carrier has not traveled through New Mexico, the carrier must file a return. Zero returns are the cheapest filings you will ever make and the most expensive ones to skip: while a quarterly return is missing, the system will not process the electronic permit, so a skipped April filing turns into a permit renewal that fails in January.
Through TAP at tap.state.nm.us. New Mexico based carriers title the vehicle at an MVD field office, file Form 2290 with the IRS at 55,000 pounds and up, apply for apportioned registration on Form MVD-11026 for interstate work, apply for IFTA, then register online for the weight distance electronic permit and file quarterly. Out-of-state carriers skip the title and the New Mexico plate but still need the WDT account and the permit.
The usual cause is an unfiled return. MVD answers the question directly: if a quarterly weight distance tax report has not been submitted, the system will not allow the weight distance e-permit to be processed. Fix it in that order, file the missing quarters first, including zero ones, settle penalty and interest, then buy the permit. Permits are also viewed, changed and inactivated inside TAP on the weight distance account summary page.
Different taxes on the same truck. IFTA settles fuel tax between member jurisdictions based on fuel bought and miles driven; the weight distance tax is New Mexico charging for road use by weight and mileage, and it goes to the State Road Fund. You file both, quarterly, and both go through TAP. In New Mexico, diesel is the only fuel classed as special fuel on an IFTA return, which is a wording difference worth knowing before you file.
Yes. MVD requires companies to register and apply each year for a New Mexico Weight Distance Tax Electronic Permit for each vehicle. It is bought in TAP, and the state allows the purchase without logging in as long as the weight distance account already exists: you supply the FEIN, the weight distance number, the USDOT number, a payment method and an email address.
The state does not issue a separate weight distance permit for a trailer. The tax is imposed on motor vehicles, and the weight class is the highest gross vehicle weight or combined gross vehicle weight declared for registration, so the trailer already sits inside the declared combination weight of the tractor. Add a heavier trailer and the class on your return changes; running above the declared weight is unlawful.
Two routes. Keep a weight distance account and an annual permit and file four returns a year, including zero ones. Or stay out of the system and pay trip tax at the port of entry at 7, 12, 15 or 16 cents per mile by weight. At 80,000 pounds that is 16 cents against 5.91 cents on a return, so even a couple of crossings a quarter usually favor the account.
Yes, in the form of trip tax paid in lieu of registration or use fees under Section 7-15-3.1 NMSA 1978. The Motor Transportation Police Division collects it, normally at a port of entry, and may authorize prepaid permits sold in increments of no less than $50. Without an IFTA license and decals you also pay five cents per mile of fuel tax plus $5.00 for a 48-hour permit valid for one trip.
All miles travelled on New Mexico roads during the quarter go into column B, detours included, because the tax is on road use and not on the shortest route. Miles already paid at a port of entry go into column C and are subtracted; the mill rate applies to the net figure in column D. Keep the port of entry receipts: the department expects you to prove the deduction.
Penalty is 2 percent of the unpaid tax per month or partial month, to a maximum of 20 percent. Interest accrues daily at a rate that changes quarterly and, by law, cannot be waived. There is also an operational cost: while a quarterly return is missing, the system will not process the electronic permit, so a late filing can stop trucks.
Write to the MVD Commercial Vehicle Bureau with the account number. All tax identification permits for the registration year go back to the bureau: cab card and plates for IRP, license and decals for IFTA, certificate and plates for weight distance base plates. Every report must be filed and every liability paid. Fax 505-476-1571, phone 1-888-683-4636 prompt 6.
Whoever is named on the valid tax identification card keeps the records of payment. Where no card is presented, the rule splits it: a rental or leasing company that leases without a driver is financially responsible as owner, and where an owner-operator and the vehicle work under the control of the lessee, the lessee is responsible. The vehicle can be detained until the tax is paid.
Yes. Senate Bill 2 of the 2026 regular session was signed on February 5, 2026 and chaptered as Chapter 4, rewriting the rate schedule in Section 7-15A-6 NMSA 1978 effective July 1, 2026. NMDOT put the increase at 35 percent, the first in more than two decades. The first class went from 11.01 to 14.86 mills per mile, the top class from 43.78 to 59.10.
Yes. IRP is registration, IFTA is fuel tax, Form 2290 is the federal heavy vehicle use tax from 55,000 pounds up, and the weight distance tax is New Mexico charging for the miles you run. None replaces another. An IRP cab card listing New Mexico does not stand in for the New Mexico Tax Identification Permit either: at the port of entry that card is what the officer asks for, and trip fees are assessed when it is not presented. The quarterly weight distance return is due either way.
