New Mexico is one of the lowest-maintenance states in the country for LLC compliance: there's no annual report to file with the Secretary of State, ever, and no franchise tax on a standard LLC. What New Mexico does have is a Gross Receipts Tax in place of a traditional sales tax — a distinction that catches out-of-state founders off guard — and a real graduated income tax reaching 5.9% on higher earners.
This guide covers exactly what a New Mexico LLC owes in 2026: the six-bracket personal income tax, how the Gross Receipts Tax actually works, why New Mexico requires zero recurring Secretary of State filings, and the $50 franchise tax trigger that only applies once you elect S-Corp status.
New Mexico Personal Income Tax on LLC Profit
By default, a New Mexico LLC is a pass-through entity — the LLC itself pays no separate income tax. Profit flows through to the owners' personal returns, taxed once at the federal level and once at New Mexico's graduated rate (1.5%–5.9%) on top, based on total taxable income for the year.
New Mexico's rate: Graduated, 6 brackets from 1.5% to 5.9%
Single-filer 2026 brackets under HB 252 (the first major restructure since 2005): 1.5% on income up to $5,500; 3.2% from $5,500–$16,500; 4.3% from $16,500–$33,500; 4.7% from $33,500–$66,500; 4.9% from $66,500–$210,000; 5.9% above $210,000. Married-filing-jointly brackets run roughly double these thresholds.
Pass-through LLC profit flows to the owner's personal PIT-1 return and is taxed at these marginal rates regardless of whether the profit was actually distributed in cash.
Does New Mexico Charge an Entity-Level Franchise Tax?
New Mexico imposes no franchise tax or minimum annual tax on standard LLCs taxed as disregarded entities or partnerships. The $50 Corporate Franchise Tax only applies once an LLC affirmatively elects corporate or S-Corp federal tax treatment — it's classification-driven, not entity-driven, the same pattern seen in several other states.
New Mexico Gross Receipts Tax
New Mexico doesn't have a traditional sales tax — it uses a Gross Receipts Tax (GRT) that's charged on nearly all business receipts, including most services, not just tangible goods. The statewide base is 5.125%, but local option taxes layered on top push combined rates as high as 9.4250% depending on where the sale is delivered. You register once through the Taxpayer Access Point (TAP) and receive a New Mexico Business Tax Identification Number (NMBTIN) — the successor to the old CRS Number.
- State rate: 5.125%, combined: 9.4250%
- Registration: Form ACD-31015 (or online via the Taxpayer Access Point), No fee fee with the New Mexico Taxation and Revenue Department
- Gross Receipts Tax returns are generally due the 25th of the month following the reporting period, with the Department assigning monthly, quarterly, or semiannual frequency based on your volume.
New Mexico Annual Report Requirement
There is no annual report filing to miss. New Mexico is one of only a handful of states that requires zero recurring Secretary of State filing for LLCs — no fee, no due date, and no administrative dissolution trigger tied to a report. You still need to keep your registered agent information current with the Secretary of State, but that's a passive obligation, not an annual filing.
Federal Self-Employment Tax and How Your New Mexico LLC Is Classified
Regardless of which state you're in, LLC owners who materially participate in the business owe federal self-employment tax — 15.3% on net profit, covering Social Security (up to the $184,500 (2026) wage base) and Medicare (no cap).
Single-Member LLCs
A single-member New Mexico LLC defaults to a disregarded entity for federal tax purposes — you report income and expenses on Schedule C of your personal Form 1040 and compute self-employment tax on Schedule SE. New Mexico adds its graduated income tax on top at the personal level.
Multi-Member LLCs
A multi-member New Mexico LLC defaults to partnership taxation, filing an informational Form 1065 and issuing each member a Schedule K-1. New Mexico has no separate filing consequence tied to member count — GRT registration and personal income tax filing apply the same either way.
Should Your New Mexico LLC Elect S-Corp Taxation?
An S-Corp election lets you split LLC profit into a reasonable salary (subject to payroll tax) and distributions (not subject to self-employment tax), once the business is consistently profitable enough to justify the added payroll complexity.
New Mexico's treatment: New Mexico recognizes the federal S-Corp election, but electing it triggers the $50/year Corporate Franchise Tax and the CIT-1 filing described above — a real, if modest, cost a default LLC doesn't carry.
Because New Mexico has real graduated personal income tax reaching 5.9%, an S-Corp election can still meaningfully reduce self-employment tax exposure on the reasonable-salary-versus-distribution split. Just factor the $50 franchise tax and CIT-1 filing into the math — it's small, but it's a cost the default structure avoids entirely. Note that the Gross Receipts Tax applies to your business's receipts regardless of entity tax election, since it taxes revenue, not entity type.

How to Handle Your New Mexico LLC's Taxes
If You Do It Yourself
Step 1 — Get your federal EIN before anything else.
Apply for your EIN for free directly at irs.gov — a purely federal application with no New Mexico-specific step.
Step 2 — Confirm your default federal tax classification.
A single-member LLC defaults to a disregarded entity (Schedule C); a multi-member LLC defaults to partnership taxation (Form 1065 plus Schedule K-1 for each member). Neither requires a separate election — this is automatic unless you file Form 8832 or Form 2553 to change it.
Step 3 — Register with the New Mexico Taxation and Revenue Department if required for state income tax withholding or estimated payments.
Pass-through LLC profit flows to the owner's personal PIT-1 return and is taxed at these marginal rates regardless of whether the profit was actually distributed in cash.
Step 4 — Register for gross receipts tax if you sell taxable goods or services.
File Form ACD-31015 (or online via the Taxpayer Access Point) with the New Mexico Taxation and Revenue Department at tap.state.nm.us, No fee fee. Gross Receipts Tax returns are generally due the 25th of the month following the reporting period, with the Department assigning monthly, quarterly, or semiannual frequency based on your volume.
Step 5 — Register for payroll/reemployment tax the moment you hire your first employee.
The moment you hire your first employee, register with the New Mexico Department of Workforce Solutions. The 2026 new-employer UI rate is a flat 2.0% for your first three years, applied to a taxable wage base of $34,800 (up from $33,200 in 2025).
Step 6 — Set up quarterly estimated tax payments.
If you expect to owe $1,000 or more in combined federal and New Mexico tax for the year, both the IRS and the Taxation and Revenue Department expect quarterly estimated payments covering income tax and federal self-employment tax on your LLC profit.
Step 8 — Decide whether an S-Corp election makes sense once your LLC is consistently profitable.
Because New Mexico has real graduated personal income tax reaching 5.9%, an S-Corp election can still meaningfully reduce self-employment tax exposure on the reasonable-salary-versus-distribution split. Just factor the $50 franchise tax and CIT-1 filing into the math — it's small, but it's a cost the default structure avoids entirely. Note that the Gross Receipts Tax applies to your business's receipts regardless of entity tax election, since it taxes revenue, not entity type.
Step 9 — Watch for New Mexico-specific tax traps.
The Gross Receipts Tax is New Mexico's single biggest structural quirk: it's assessed on gross receipts, not net profit like most states' sales tax, and it nominally falls on the seller (even though it's typically passed through to the buyer on an invoice) — a distinction that trips up founders coming from traditional sales-tax states. The rate also varies by the location where the good or service is delivered, not just where your business is registered, so multi-location or multi-city LLCs need to track destination-based combined rates carefully.
Step 10 — Keep business and personal finances completely separate.
Commingling funds is the single biggest reason courts pierce the LLC liability shield, and it also makes tax preparation far more error-prone. Run all business income and expenses through a dedicated business bank account and keep receipts.

When Should You Talk to a Tax Professional About Your New Mexico LLC?

Frequently Asked Questions
Not for a default LLC. New Mexico imposes no franchise tax or minimum annual tax on standard disregarded-entity or partnership-taxed LLCs. The only trigger is electing S-Corp or C-Corp federal tax treatment, which pulls the entity into a flat $50/year Corporate Franchise Tax filed on Form CIT-1.
New Mexico doesn't have a traditional sales tax — it has a Gross Receipts Tax (GRT) charged on nearly all business receipts, including most services. Register for free through the Taxpayer Access Point (TAP) or Form ACD-31015, then collect the statewide base rate of 5.125% plus any local add-ons, which combine up to 9.4250% depending on where the sale is delivered.
There isn't one. New Mexico is one of only a handful of states with no annual or biennial report requirement for LLCs — no fee, no due date, and nothing to file with the Secretary of State beyond keeping your registered agent information current.
Because New Mexico has no annual report, there's no report-related deadline to miss or late penalty to incur. Your main recurring risk is instead on the tax side: missing Gross Receipts Tax filing deadlines (generally the 25th of the month following the reporting period) can trigger penalties and interest from the Taxation and Revenue Department.
It depends on your profit level. New Mexico's graduated income tax (up to 5.9%) means an S-Corp election can meaningfully reduce self-employment tax exposure through the reasonable-salary-versus-distribution split — but electing S-Corp status also triggers a new $50/year Corporate Franchise Tax and CIT-1 filing that a default LLC doesn't have to make. Weigh the SE-tax savings against that added cost and complexity.
A single-member New Mexico LLC defaults to a disregarded entity for federal tax purposes — you report income on Schedule C and pay self-employment tax via Schedule SE. New Mexico adds its graduated income tax (1.5%–5.9%) on top at the personal level, with no separate state filing for the LLC itself.
If your LLC does business in a state other than the one it's formed in — an office, employees, inventory, or significant sales there — you may have created nexus requiring registration and tax obligations in that state too. This is fact-specific and worth a conversation with a tax professional if you operate in multiple states.
For a typical New Mexico LLC with in-state owners and no employees: graduated state income tax from 1.5% up to 5.9% on your share of profit, no annual report fee, no franchise tax (unless you elect S-Corp status), plus federal income tax and 15.3% federal self-employment tax (up to the $184,500 Social Security wage base for 2026). Add the Gross Receipts Tax (5.125%–9.4250% depending on location) if you sell goods or services.
Yes. LLC Attorney's ongoing compliance subscription tracks your New Mexico filing deadlines, handles your annual report, and connects you with flat-fee attorney consultations (no retainer) when a tax question needs a licensed professional's judgment call.
