New Mexico does not have a sales tax in the traditional sense, so New Mexico sales tax filing really means filing the state’s gross receipts tax (GRT). The tax is imposed on the business for the privilege of doing business in the state, not on the customer, and the legal duty to report and pay sits with you even when you pass the charge along on a receipt.1New Mexico Taxation and Revenue Department. Gross Receipts Tax Overview You register with the Taxation and Revenue Department, report your receipts by location code through the Taxpayer Access Point (TAP), and pay by the 25th of the month after your reporting period closes.
Who Has to Register
Any business “engaging in business” in New Mexico must register and get a New Mexico Business Tax Identification Number (NMBTIN). Under Section 7-9-3.3, that phrase covers carrying on any activity for direct or indirect benefit in the state, which pulls in anyone with an office, employees, inventory, or other physical footprint.2Justia. New Mexico Code 7-9-3.3 – Definition; Engaging in Business
Remote sellers without physical presence still have to register once their taxable gross receipts from New Mexico sources hit $100,000 in the previous calendar year. The same economic nexus threshold applies to marketplace providers.2Justia. New Mexico Code 7-9-3.3 – Definition; Engaging in Business Whether you itemize the tax on customer invoices is your call. The liability stays with the business either way.1New Mexico Taxation and Revenue Department. Gross Receipts Tax Overview
Finding the Right Rate for Each Sale
The state rate is 4.875 percent, but counties and municipalities add their own local increments on top. A sale in Albuquerque is taxed at a different combined rate than one in Las Cruces or a rural county, and your return has to break receipts out by the location code that applies to each transaction.
The Taxation and Revenue Department publishes rate schedules and an interactive map tool that returns the correct location code and combined rate for any address.3New Mexico Taxation and Revenue Department. Gross Receipts Location Code and Tax Rate Map For deliveries, the code tracks to the destination, not your office. Rates can change on July 1 and January 1, so check the schedule each time those dates come around. Mismatched location codes are the single most common source of both underpayment and overpayment.
How Often You File
The department assigns your filing frequency based on your average monthly GRT liability. Businesses averaging under $200 a month generally file semiannually. Those between $200 and $500 file quarterly. Above that, you file monthly. The department can shift your frequency as your revenue changes.
No matter the frequency, returns and payments are due by the 25th of the month after the reporting period closes. A January monthly return is due February 25. A first-quarter return covering January through March is due April 25. If the 25th lands on a weekend or holiday, the deadline moves to the next business day. Give yourself a few days of buffer; penalties and interest start the day after.
Filing Through TAP
Returns go through the Taxpayer Access Point at tap.state.nm.us. Electronic filing is recommended for everyone and required for businesses above certain liability thresholds.1New Mexico Taxation and Revenue Department. Gross Receipts Tax Overview From a single TAP account you can file, amend, pay, and manage your Nontaxable Transaction Certificates.4New Mexico Taxation and Revenue Department. Online Services
Before you log in, pull your gross receipts for the period and sort them by location code. For each code you enter gross receipts and any deductions, and TAP applies the correct rate. You certify with an electronic signature and submit.
Pay by ACH debit from a bank account or by credit card, though the card option carries a vendor processing fee. Paper filers can print a voucher and mail a check. Save the confirmation number and downloadable receipt TAP generates after a successful submission. If a filing date is ever disputed, that confirmation is the proof.
Claiming Deductions and Using NTTCs
Not every dollar of gross receipts is taxable. Section 7-9-47 lets you deduct sales of tangible personal property or licenses to a buyer who will resell them in the ordinary course of business.5Justia. New Mexico Code 7-9-47 – Deduction; Gross Receipts; Tangible Personal Property and Licenses Sold for Resale Section 7-9-46 covers sales to manufacturers who incorporate your product as an ingredient or component in what they make.6Justia. New Mexico Code 7-9-46 – Deduction; Gross Receipts; Governmental Gross Receipts; Sales to Manufacturers and Manufacturing Service Providers Other deductions cover unprocessed agricultural products, isolated or occasional sales by someone not in that line of business, and interstate telecommunications services; the department’s site lists the full set with statute citations.
Most deductions require a Nontaxable Transaction Certificate (NTTC) from the buyer. The buyer generates the NTTC through TAP using their own NMBTIN, and one certificate covers all transactions of the same type with that customer going forward. A properly executed NTTC accepted in good faith is conclusive evidence that the receipts qualify for the deduction.7New Mexico Taxation and Revenue Department. Non-Taxable Transaction Certificates (NTTC)
Resale certificates from other states do not work in New Mexico. Out-of-state buyers who are not required to register here can instead use a Multijurisdictional Sales and Use Tax Certificate from the Multistate Tax Commission or a Border States Uniform Sale for Resale Certificate.7New Mexico Taxation and Revenue Department. Non-Taxable Transaction Certificates (NTTC) Sellers used to accepting Texas or Arizona resale certificates get caught by this regularly.
Selling Through a Marketplace
If your sales run through a marketplace like Amazon or Etsy, the platform generally collects and remits GRT on those transactions. A “marketplace provider” is a person who facilitates a sale by listing or advertising it and collecting payment on the seller’s behalf,8Justia. New Mexico Code 7-9-3 – Definitions and under Section 7-9-3.5 the receipts from facilitated sales are included in the provider’s taxable gross receipts regardless of whether the individual seller has nexus in New Mexico.9New Mexico Taxation and Revenue Department. FYI-206: Gross Receipts Tax and Marketplace Sales
The handoff is only for marketplace sales. If you also sell through your own website, at trade shows, or from a storefront, those receipts are still yours to report. Keep marketplace and direct sales separate in your books so you do not double-report.
Compensating Tax on Out-of-State Purchases
Compensating tax is the companion to GRT and applies when you buy tangible personal property, services, or licenses from an out-of-state seller who did not charge New Mexico GRT, and you use the item in the state. The rate matches the state GRT base at 4.875 percent.10Justia. New Mexico Code 7-9-7 – Imposition and Rate of Tax Equipment, supplies, and software ordered online from vendors without New Mexico nexus commonly trigger it. You report and pay it on your regular GRT return through TAP.
What Happens If You File Late
The late-filing penalty is 2 percent of the unpaid tax per month or partial month, capped at 20 percent, with a $5 minimum.11Justia. New Mexico Code 7-1-69 – Civil Penalty for Failure to Pay or File The penalty accrues from the original due date, so five months late on a $10,000 liability means $1,000 in penalty on top of the tax, plus interest.
If the department finds the failure was willful, meaning a deliberate attempt to evade the tax, the penalty jumps to 50 percent of the tax owed or $25, whichever is greater. There is one meaningful exception: a good-faith mistake of law on reasonable grounds carries no penalty. That protects a business that misread a genuinely ambiguous rule, not one that simply forgot to file.11Justia. New Mexico Code 7-1-69 – Civil Penalty for Failure to Pay or File If the department sends a demand for payment and you pay in full within ten days, no additional penalty accrues after the demand date.
Fixing a Return You Already Filed
Catching an error yourself is always better than letting the department find it. You can amend a GRT return through TAP by opening the relevant filing period and correcting the figures.4New Mexico Taxation and Revenue Department. Online Services If you underpaid, interest runs from the original due date, so filing the amendment sooner costs you less. If you overpaid, the amendment starts the refund.
Paper filers use the same return form with the “amended” box checked. Keep documentation showing which transactions changed and why. An auditor reviewing an amended return wants to see the specific corrections, not just a different total.
How Long to Keep Records
New Mexico’s state records retention schedule calls for keeping tax reports for ten years from the close of the calendar year in which the file was closed.12New Mexico State Records Center and Archives. 1.21.2 NMAC – General Records Retention and Disposition Schedules Federal IRS guidance is shorter: generally three years from the date you filed, six if you underreported income by more than 25 percent, and indefinitely if you never filed.13Internal Revenue Service. How Long Should I Keep Records?
Plan on ten years for GRT records: invoices, NTTCs, location-code documentation, and the filed returns themselves. NTTCs executed through TAP stay on file with the department, but keeping your own copies next to the underlying transactions saves time if a deduction is ever questioned.
