Who we would hire in New Mexico
1. Mainstay Filing: best for one provider for both jobs
Mainstay Filing earns the highest mark because the filing and a year as your registered agent cost $199, and renewal brings no increase.

Forming the LLC in order
-
Step
1Settle on a name
Use the business search at the New Mexico Secretary of State to see whether another New Mexico company already holds your name; a clash can get the filing sent back.
Check whether the matching web domain is free while you are at it.
-
Step
2Appoint a registered agent
Every LLC must name a registered agent with an in-state street address. A New Mexico resident, or a corporation, LLC or partnership formed in New Mexico or authorized there whose place of business is the registered office.
The address has to be a street address in New Mexico. P.O. boxes are not accepted.
Any service in our graded list can be your registered agent.

Step
3Choose between DIY and a service
Doing it yourself means $50 to the state and nothing else. One of our picks charges $199 on top and takes over the paperwork.
-
Step
4Turn in the Articles of Organization
To form the LLC, pay $50 and give the Articles of Organization to the New Mexico Secretary of State; the authority is NMSA 1978, § 53-19-7.

Step
5Apply for an EIN
Once approved, the LLC can get a federal tax ID, the EIN, from the IRS. A business bank account will need it. Mainstay Filing includes the EIN application in its yearly price.
-
Step
6Agree on the ground rules in writing
Think of the operating agreement as the LLC's rulebook: who owns what, kept by you and not sent to the state.
-
Step
7Keep up with New Mexico's recurring filing
New Mexico asks nothing of the LLC each year in the way of a report; your job is keeping a registered agent current.
New Mexico costs by step
| Line | Payee | Amount |
|---|---|---|
| Formation filing | State office | $50 |
| Help from a service | Service company | $199 in the first year |
| State fees for three years | State office | $50 |
