New Mexico is the only state in the country with no annual or biennial report requirement for LLCs at all. File once, keep a registered agent on file, and the state genuinely leaves you alone after that. Here's what it takes to start a business in New Mexico in 2026.
1. Which business structure fits you?
Before you file anything, it helps to know what you're actually choosing between.
- Sole proprietorship. No filing required to start, and you and the business are legally the same entity. Simple, but you're personally liable for whatever the business owes.
- Partnership. Two or more people running a business together, with the same liability exposure as a sole proprietorship, just split across partners.
- LLC. The most common structure for small businesses in New Mexico. It separates your personal assets from the business's debts and lawsuits.
- Corporation, either S-corp or C-corp. More paperwork and more formality, usually worth it once you're bringing on investors or multiple shareholders.

LLCs and corporations register with the New Mexico Secretary of State, Business Services Division, the agency that handles business filings statewide. Sole proprietorships and general partnerships don't register there.
2. Register your business
Forming an LLC
You form an LLC in New Mexico by filing Articles of Organization with the Secretary of State. The filing fee is $50, and online processing is typically fast.
Every LLC needs a registered agent with a physical New Mexico address, available during business hours. You can act as your own agent, or hire a commercial service. New Mexico's public entity record notably doesn't require you to disclose member or manager names, giving you more privacy on the state filing than most states offer.
New Mexico doesn't require an operating agreement to be filed with the state, but keep one with your company records regardless.
Sole proprietorships and DBAs
Sole proprietorships don't file Articles of Organization. Trade name registration requirements for sole proprietors vary by county in New Mexico.
3. Get an EIN
An Employer Identification Number is free straight from the IRS and takes about 15 minutes online. You'll need one to open a business bank account, hire anyone, or file most business tax forms, even if you're a single-member LLC with no employees.
4. Check licenses and permits
New Mexico doesn't issue a single general statewide business license either. What you need depends on your industry and city: professional licensing for regulated fields, local permits in some cities, and registration with the Taxation and Revenue Department if you sell taxable goods or services, since New Mexico taxes those through the Gross Receipts Tax rather than a conventional sales tax. Our guides on professional licensing by industry and zoning laws for home businesses cover more of this.
5. Understand New Mexico taxes
New Mexico has a progressive personal income tax, up to 5.9% at the top. Pass-through LLCs owe no separate franchise tax. If your LLC elects corporate treatment, the corporate income tax rate is a flat 5.9%.
Instead of a traditional sales tax, New Mexico applies a Gross Receipts Tax (GRT) on the seller, which reaches many services and business-to-business transactions that a typical sales tax wouldn't touch. The statewide base is 4.9%, with counties and municipalities adding local GRT on top, landing combined rates between roughly 6.5% and 9% depending on where you're doing business.
6. Stay compliant
This is the shortest compliance section in this whole series, because New Mexico requires no annual report, no biennial report, and no franchise tax for standard LLCs. Once your Articles of Organization are approved, there's no scheduled state filing to remember at all. Your only real ongoing obligation is keeping your registered agent current, since it's the state's one way of reaching you if something needs your attention.
