New Mexico Compensating Tax: Rates, Filing, and Penalties

The New Mexico compensating tax is an excise tax you owe on purchases and other transactions used in the state when the seller didn’t collect New Mexico gross receipts tax. The current state rate is 4.875%, and most locations add a municipal compensating tax on top. It works like a use tax: if you buy from an out-of-state vendor with no New Mexico nexus, the obligation to pay the tax shifts to you.

When You Owe Compensating Tax

The tax reaches three kinds of transactions, all tied to receipts that escaped the gross receipts tax.¹

Tangible personal property you manufactured in New Mexico and converted to your own use, or acquired from an out-of-state seller that lacks nexus with the state.
Licenses and franchises used in New Mexico when acquired in a transaction not subject to gross receipts tax.
Services performed outside New Mexico whose product is used in the state, if the transaction would have been subject to gross receipts tax had the provider had nexus here.

“Use” is defined broadly to include use, consumption, and storage. Only two situations fall outside it: storing goods solely for later resale in the ordinary course of business, and storing goods for use exclusively outside the state.² Common triggers include construction equipment bought from a Texas seller, software licenses from an out-of-state corporation, and engineering plans from a Colorado firm that you use in Albuquerque.

One important qualifier limits the reach of the tax. It only applies to transactions that would have been subject to gross receipts tax if they had occurred in New Mexico. If a deduction or exemption under the Gross Receipts and Compensating Tax Act would have covered the transaction anyway, no compensating tax is owed.¹

What You’ll Pay: State and Local Rates

The state compensating tax rate is 4.875%, effective since July 1, 2023.¹ A contingency provision in the statute allows the secretary of finance and administration to certify an increase to 5.125% if gross receipts tax revenues for any fiscal year between FY2026 and FY2029 fall below 95% of the prior year’s collections.³ That trigger has not been activated, so 4.875% remains the operative rate.

Layered on top is the municipal compensating tax. Since July 1, 2021, municipalities impose their own compensating tax at a rate equal to the combined local gross receipts tax rates in effect under the Supplemental Municipal Gross Receipts Tax Act and the Municipal Local Option Gross Receipts and Compensating Taxes Act.⁴ The local rate depends on where you use the property, service, or license, and combined rates vary meaningfully from one city to the next. Your total bill is the state 4.875% plus whatever local rate applies to your municipality.

Credit for Tax Already Paid to Another State

If you paid a sales tax, use tax, or similar excise tax to another state on the same property or services, you can credit that amount against your New Mexico compensating tax. The credit cannot exceed the compensating tax otherwise due, so it can zero out a balance but never generate a refund on the other side.⁵ If you bought equipment in Arizona and paid Arizona sales tax, you subtract that amount from what you’d otherwise owe New Mexico; if the Arizona tax equals or exceeds the New Mexico figure, nothing is due here.

Construction businesses get a separate credit. If you paid compensating tax on materials or construction services that became part of a project, and the sale of the completed real property is subject to gross receipts tax, you can credit the earlier compensating tax against the gross receipts tax due on the sale. That prevents the same materials from being taxed twice.⁵

Deductions and Nontaxable Transaction Certificates

Because the compensating tax mirrors the gross receipts tax’s exemption structure, transactions that would have qualified for a deduction had they taken place in-state are not subject to compensating tax either. Deductions are typically supported by a Nontaxable Transaction Certificate, or NTTC. A properly executed NTTC accepted in good faith is conclusive evidence that the transaction qualifies.⁶ Only buyers with a valid registration number (or a pending application not yet refused) can execute one.

Without an NTTC, you can still support a deduction with alternative evidence: invoices describing the transaction, records of how the property was used or disposed of, or a written statement from the buyer that the property was purchased for resale. The party claiming the deduction carries the burden of proof, and a materially false NTTC shifts the tax, penalties, and interest onto the buyer who signed it.⁶

How and When to File

Compensating tax is reported on Form TRD-41412, the Compensating Tax Return.⁷ Many businesses fold the figures into their combined monthly or quarterly gross receipts tax reporting rather than filing a standalone return. Either way, you’ll use your New Mexico Business Tax Identification Number (NMBTIN), the 11-digit number formerly known as the CRS ID.⁸

The main filing channel is the department’s Taxpayer Access Point (TAP), which handles electronic filing and payment by bank transfer or credit card and gives you an immediate digital record.⁹ Paper returns are also accepted by mail.

Returns and payments are due by the 25th of the month after the period in which the taxable transaction occurred.¹⁰ Equipment purchased on March 10 shows up on a return due by April 25. Before filing, pull the invoices for every out-of-state purchase that came in without New Mexico tax; each one should show the price, date, and a description you can tie to a line on the return.

Penalties and Interest

Miss the deadline and a penalty of 2% per month, or any fraction of a month, accrues on the unpaid tax, capped at 20% of the tax due. The minimum penalty is $5 even when the percentage would produce less.¹¹ Being a few days late is treated the same as being a full month late for that first increment.

Willful evasion is treated much more severely. If the Taxation and Revenue Department finds you willfully avoided the tax, the penalty is 50% of the unpaid amount or $25, whichever is greater.¹¹

Interest runs separately from penalties. It accrues on underpayments at the federal underpayment rate set under Section 6621 of the Internal Revenue Code, calculated daily, from the original due date until the tax is paid.¹² Because the federal rate floats, it can change quarterly.

Protesting an Assessment

If the department issues an assessment you believe is wrong, you have 90 days from the mailing date of the notice to file a written protest with the department secretary.¹³ Miss that window and the assessment becomes final; the only remaining path is to pay in full and file a refund claim.

The protest must identify you, the tax involved, the factual and legal grounds for the dispute, and the specific relief you want. You do not have to pay the disputed portion before protesting, but any part of the assessment you’re not contesting must be paid by the deadline. When only part of a bill is wrong, pay the undisputed portion and protest the rest.¹³
