Ask around and you'll find New Mexico stands alone on one particular point: it's the only state that never makes LLCs file an annual or biennial report. File the paperwork once, keep a registered agent on record, and that's genuinely the extent of what the state asks of you going forward. Here's a rundown of what starting a business in New Mexico actually requires in 2026.
1. Which business structure fits you?
The structure question comes down to liability protection versus paperwork, same as anywhere else, so it's worth sorting out early.
- Sole proprietorship. Nothing to file to get started, but no legal separation from the business exists either, so its debts become your debts.
- Partnership. Multiple people running the business together, carrying the same unlimited liability a sole proprietor does, just spread across owners.
- LLC. The default pick for small New Mexico businesses, since it draws a legal line protecting your personal assets from the business's debts and lawsuits.
- Corporation, S-corp or C-corp. Comes with more formality and filing obligations, usually worthwhile once investors or multiple shareholders enter the picture.
Our guide on choosing a business structure breaks the comparison down further.
LLCs and corporations register through the New Mexico Secretary of State's Business Services Division, which manages business filings for the state. Sole proprietors and general partnerships have no need to register there.
2. Register your business
Forming an LLC
An LLC comes into being in New Mexico once you file Articles of Organization with the Secretary of State. It costs $50, and online filings are generally processed quickly.
Every LLC also needs a registered agent at a physical New Mexico address, reachable during business hours — you can serve that role yourself or bring in a commercial service. One quirk worth knowing: New Mexico's public entity record skips requiring member or manager names, which gives owners more privacy on the public filing than most other states allow.
You won't file an operating agreement with the state — New Mexico doesn't ask for one — but it's still worth putting one together and keeping it in your own company records.
Sole proprietorships and DBAs
Articles of Organization aren't something sole proprietors file. Registering a trade name as a sole proprietor works differently depending on which New Mexico county you're in.
3. Get an EIN
Applying for an Employer Identification Number directly through the IRS costs nothing and takes about 15 minutes online. Opening a business bank account, hiring anyone, and filing most business tax forms all require one, even for a single-member LLC with zero employees.
4. Check licenses and permits
No single statewide business license exists in New Mexico. What applies to you hinges on your industry and city instead: certain regulated professions need licensing, some cities layer on local permits, and selling taxable goods or services means registering with the Taxation and Revenue Department, since New Mexico taxes those transactions through its Gross Receipts Tax rather than a standard sales tax. Our guides on professional licensing by industry and zoning laws for home businesses cover the details.
5. Understand New Mexico taxes
Personal income tax in New Mexico is progressive, topping out at 5.9%. LLCs taxed as pass-throughs don't face a separate franchise tax on top of that; electing corporate treatment instead means a flat 5.9% corporate income tax rate.
Rather than a conventional sales tax, New Mexico charges a Gross Receipts Tax (GRT) on sellers, which catches many services and business-to-business transactions that an ordinary sales tax would miss entirely. The statewide base sits at 4.9%, and counties and cities add their own local GRT on top, so combined rates typically fall somewhere between about 6.5% and 9% depending on location.
6. Stay compliant
Compliance in New Mexico barely needs a section, honestly, because there's no annual report, no biennial report, and no franchise tax for a standard LLC to worry about. Once the Secretary of State approves your Articles of Organization, there's no recurring state filing sitting on your calendar. The one thing you do need to stay on top of is your registered agent, since that's the state's sole channel for reaching you if anything comes up.
