Starting a New Mexico LLC is straightforward. You file paperwork with the New Mexico Secretary of State, pay the $50 filing fee, and wait for approval. No lawyer required.
This guide walks you through the entire process step-by-step, including costs, timelines, required forms, and common mistakes to avoid.
Step-by-Step Guide to Forming a New Mexico LLC
-
Choose Your LLC Name
Your New Mexico LLC name must:
- Include "Limited Liability Company," "LLC or L.L.C."
- Be distinguishable from existing New Mexico businesses
- Not contain restricted words (bank, insurance, corporation) without approval
Check name availability: New Mexico Secretary of State Business Search
⚠️ Common Mistake: Don't skip the name search. If your name is too similar to an existing business, your filing will be rejected and you'll lose the $50 fee. -
Appoint a Registered Agent
New Mexico requires every LLC to have a registered agent—a person or company authorized to receive legal documents on behalf of your business.
Requirements:
- Must have a physical New Mexico address (no P.O. boxes)
- Must be available during normal business hours
- Can be yourself, a partner, or a professional service
Cost: $0 if you act as your own agent. Professional services cost $100-300/year.
-
File Articles of Organization
This is the official document that creates your LLC. You'll submit it to the New Mexico Secretary of State.
Required information:
- LLC name
- Purpose of business (can be general)
- Registered agent name and address
- Management structure (member-managed or manager-managed)
- Principal office address

Create an Operating Agreement
While not always legally required, an Operating Agreement is highly recommended. It defines ownership percentages, profit distribution, management structure, and procedures for adding/removing members.
Why you need it:
- Protects your limited liability status
- Prevents disputes between members
- Required by most banks to open a business account
💡 Pro Tip: Even if you're a single-member LLC, create an Operating Agreement. It strengthens the legal separation between you and your business. -
Get an EIN (Employer Identification Number)
An EIN is like a Social Security number for your business. You need it to open a bank account, hire employees, and file taxes.
How to get it: Apply free online at the IRS website. Takes 10 minutes, receive immediately.
Cost: $0 (free from the IRS)
⚠️ Scam Alert: Third-party services charge $50-200 for EIN applications. Don't pay. The IRS does this for free. -
Annual Reporting
Good news! New Mexico does not require annual reports for LLCs, saving you time and money on ongoing compliance.
✓ Advantage: No annual report means less paperwork and lower ongoing costs compared to many other states.

Common Mistakes to Avoid
1. Skipping the Operating Agreement
Banks often won't open business accounts without one. Plus, it protects you in disputes and strengthens your liability protection.
2. Not Separating Personal and Business Finances
Open a dedicated business bank account immediately. Mixing personal and business funds can "pierce the corporate veil" and eliminate your liability protection.
3. Forgetting Ongoing Compliance
While New Mexico doesn't require annual reports, you still need to maintain your LLC properly—keep records, file taxes, and maintain your registered agent.
4. Using Your Home Address as Registered Agent
Your registered agent address is public record. If you value privacy, consider using a professional registered agent service or a business address.
5. Paying Third-Party "EIN Services"
Scammers charge $50-200 to file for your EIN. The IRS does this for free at irs.gov. Never pay for an EIN.
New Mexico LLC Tax Information
New Mexico imposes state income tax at individual rates (1.7-5.9%). The Gross Receipts Tax functions as a sales tax.
Federal taxes: By default, LLCs are "pass-through" entities—profits pass through to your personal tax return. Single-member LLCs are taxed as sole proprietorships. Multi-member LLCs are taxed as partnerships. You can also elect S-corp or C-corp taxation if beneficial.
Do You Need a Lawyer?
Short answer: No.
Forming a New Mexico LLC is simple enough to do yourself. The forms are straightforward, and the New Mexico Secretary of State website has instructions.
When you might want a lawyer:
- Complex ownership structures (multiple members with different equity stakes)
