New Mexico LLC Gross Receipts Tax — Step 6 of 8
Since New Mexico has no annual report and no franchise tax, this is the one recurring compliance item that actually applies to most New Mexico LLCs: registering for a free Business Tax ID if you're "engaging in business" in the state. Here's how to tell if that's you, and how to register.
If your LLC is "engaging in business" in New Mexico, register with the Taxation and Revenue Department for a free Business Tax Identification Number (NMBTIN) through the Taxpayer Access Point (TAP) portal. This covers Gross Receipts Tax (New Mexico's substitute for sales tax), and other programs like withholding tax if you have employees. Registration is always free and usually instant online.

What the Gross Receipts Tax Actually Is
New Mexico doesn't have a traditional sales tax. Instead, it uses the Gross Receipts Tax (GRT) — legally a tax on the business, not the customer, though the cost is nearly always passed on at checkout. It's broader than a normal sales tax because it applies to services as well as goods — legal, consulting, and accounting services are taxable here in a way they typically aren't elsewhere.
To collect and remit GRT (or handle withholding tax if you have employees), you need a New Mexico Business Tax Identification Number (NMBTIN) — formerly called a CRS number — from the Taxation and Revenue Department.

Filing frequency depends on your volumeAfter registering, the Taxation and Revenue Department assigns you a filing frequency — monthly, quarterly, or semiannually — based on your expected tax liability. You'll file and pay GRT returns through your TAP account going forward. Combined rates range roughly 5.1% to 9.4% depending on where the sale is sourced.
