Here are the steps to forming an LLC in New Mexico
1. Search your LLC Name
Search your LLC Name to make sure it’s available in the state.
You need to do this because two businesses in the state can’t have the same name.
First, search your business name and compare it to existing businesses in the state. You can make sure the LLC Name you want is unique from existing businesses using the NM Secretary of State: Business Search.
Second, familiarize yourself with the state’s naming rules (so your LLC gets approved).
We’ll explain both in more detail here: New Mexico LLC Name.
2. Choose a Registered Agent
The next step is to choose a Registered Agent.
Who can be an LLC Registered Agent?
You have 3 options for who can be the Registered Agent:
- You
- A friend or family member
- A Registered Agent Service
The Registered Agent for your LLC must have a physical street address in New Mexico. PO Boxes aren’t allowed.
And the Registered Agent’s name and address will be listed on public records.
If you don’t have a physical street address in New Mexico, or you want more privacy, you can hire a Registered Agent Service for your LLC.

4. Create an Operating Agreement
The Articles of Organization creates your LLC, and the Operating Agreement shows who owns the LLC.
Additionally, some banks require an Operating Agreement when you open an LLC bank account.
And having an Operating Agreement will be very helpful if you ever end up in court. Reason being, it helps prove that your LLC is being run properly.
That’s why we recommend that all LLCs have an Operating Agreement – including Single-Member LLCs.
Furthermore, an Operating Agreement is an “internal document“. Meaning, you don’t need to file it with any government agency (like the New Mexico Secretary of State or the IRS. Just keep a copy with your business records.
You can download a free template below.
Then, learn how to fill it out by watching our step-by-step New Mexico Operating Agreement video.
5. Get an EIN for your LLC
The next step is to get a New Mexico EIN Number from the IRS (Internal Revenue Service) for your LLC.
Note: An EIN Number is also called a Federal Tax Identification Number or Federal Employer Identification Number.
- identify your LLC for tax purposes
- open a business bank account
- apply for business licenses and permits
How much does an EIN cost?
Getting an EIN Number from the IRS is completely free.
How long does it take to get an EIN?
If you apply online, it takes 15 minutes.
If you apply by mail or fax, it can take 1-3 months.

US Citizens/US Residents: If you have an SSN or ITIN, you can apply for an EIN online. Follow these instructions: Apply for an EIN online.

6. Register for a Tax ID Number in New Mexico
All LLCs must register with the Taxation & Revenue Department and get a New Mexico Tax Identification Number.
This state tax ID is required to do business in the state, and is different from your LLC’s federal EIN number.
You can register online through Taxpayer Access Point.
And you can read more about the Tax ID requirement from the New Mexico Taxation & Revenue Department: Who must register a business?
What do I do after my LLC is approved?
After your LLC is approved, there are some additional steps.
Open an LLC business bank account
You’ll want to open a business bank account for your LLC.
This makes accounting and record-keeping much easier for your business finances.
Having a separate business bank account also maintains your personal liability protection. This is because it keeps your business entity finances separate from your personal finances.
Get business licenses and permits
Good news, New Mexico doesn’t have a state general business license.
However, depending on where your LLC is located, you may need a local business license or permit.
For example, if you want to start a daycare, you may need a business license from the city or county.
You can learn more on our New Mexico LLC Business License page.
File and pay taxes
LLCs don’t pay federal taxes. Instead, the LLC Members pay the taxes for the LLC.
Said another way, the owners pay taxes for the LLC as a part of their personal tax returns.
How will my LLC be taxed?
By default, an LLC is taxed by the IRS based on the number of owners your LLC has:
- A Single-Member LLC is taxed like a Sole Proprietorship.
- A Multi-Member LLC is taxed like a Partnership.
Alternatively, you can ask the IRS to tax your LLC like a C-Corporation or S-Corporation.
Married Couples: Instead of having your LLC taxed as a Partnership, married couples can elect to be taxed as a Single-Member LLC (aka Qualified Joint Venture). This is allowed in New Mexico because it’s a community property state.
Besides federal taxes, there are also state and local income taxes – and gross receipts tax.

How to Start an LLC in New Mexico FAQs
Can I start an LLC online in New Mexico?
Yes, you can file your LLC online in New Mexico. The Articles of Organization filing fee is $50.
When you start your LLC online, it will be approved 1-3 business days.
What are the benefits of an LLC?
The first benefit of an LLC is protecting your personal assets. Meaning, if your business is sued, your personal assets – like your home, cars, and bank accounts – are protected.
This protection applies to all LLC owners (called LLC Members). It doesn’t matter if you have a Single-Member LLC or Multi-Member LLC. All of the LLC owners are protected from the business debts and liabilities.
This type of protection wouldn’t apply if you operate as a Sole Proprietorship or Partnership. With these types of informal business structures, the owners aren’t protected in the event of a lawsuit. For that reason, Limited Liability Companies (LLCs) are a much more popular business structure.
And New Mexico state income taxes are very similar, since the state honors the federal tax structure of your LLC.
To learn more, please see How are LLCs taxed.
Is New Mexico a good state to start an LLC?
Whether New Mexico is a good state to start an LLC depends on where you live – and where you’re doing business.
Meaning, if you live in or do business in New Mexico, then you should start your LLC there. While many websites talk about tax rates and advantages of certain states, none of that applies if it’s not the state where you live and do business.
For example, if you form an LLC in Nevada, but live in and conduct business in New Mexico, you’ll also need to register your Nevada LLC in New Mexico (and pay extra fees). And you’ll end up paying New Mexico taxes anyway. This ends up leading to more costs and more headaches with no advantages.
In summary, if you live in and conduct business in New Mexico, then yes, New Mexico is a good state to start a business. If you don’t live in and do business in New Mexico, then no, it isn’t a good state to start a business.
Real estate exception: If you’re purchasing real estate outside of New Mexico, you should form your LLC in the state where the property is located.
For more information, please see Best State to Form an LLC.
Do I need to file a New Mexico Annual Report?
Although most states have annual reports and fees, New Mexico is one of the few states that doesn’t require LLCs to file (or pay) an Annual Report.
For more information, see: New Mexico LLC Annual Report.
What is the difference between a Domestic LLC, a Foreign LLC, and a PLLC?
The main differences between Domestic LLCs, Foreign LLCs, and Professional LLCs are where they are formed and their business purpose.
A Domestic Limited Liability Company is an LLC that is formed in its “home state”, meaning, where the business owner lives and does business.
For example, if you live in and do business in New Mexico, you would form your Domestic LLC in New Mexico.
A Foreign Limited Liability Company is an LLC that is formed in a state that isn’t its home state. In this case, the term “foreign” simply means that the LLC is foreign to its “home state”.
For example, if you live in and do business in New Mexico, you would form your Domestic LLC in New Mexico. If you later expand into Arizona, you would register your existing New Mexico LLC as a Foreign LLC in Arizona.
Said another way, LLCs are created at the state-level.
And if you want your LLC to do business in two separate states, you have to form or register an LLC in both states.
This works by forming a Domestic LLC in your home state, and a Foreign LLC in the other state.
What is a PLLC?
A Professional Limited Liability Company (PLLC) is a type of LLC formed for the purpose of providing “professional services”.
In this case, “professional” refers to business types that require special permissions (like a license, registration, or certification from the state) in order to do business legally.
For example, architects, attorneys, and social work counselors, doctors, and veterinarians are required to register their businesses as PLLCs.
You can read more about PLLCs, their availability, and their stricter requirements in: What’s a Professional LLC?
