What owners want to know

Do I have to name a registered agent?

Every LLC must name a registered agent with an in-state street address.

The law behind it: NMSA 1978, § 53-19-5. looked up at nmonesource.com in October 2026 to confirm

Who is allowed to be the agent?

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.

If you meet the rule, name yourself and pay no agent fee.

How much does an agent cost?

$99 to $149 a year with the services we recommend, which works out to $297 to $447 over three years.

No state fee depends on which agent you name.

What does an agent do for the LLC?

Think of it as the LLC's mailbox in New Mexico for court papers and government letters.

What counts is that nothing important sits unseen while you are traveling. What is service of process?

What does the LLC owe the state each year?

Nothing repeats on the report side, because New Mexico asks for no report.

What put number one on top?

On chores the price takes care of, worth 29%, Mainstay Filing comes out ahead.

Two questions carry most of the weight, what you pay over three years (33%) and chores the price takes care of (29%), and three smaller ones follow.

Only the first pick works in all fifty states, and that matters the day the LLC registers elsewhere.

Still wondering?

Can I be my own agent?

Often you can. If your address and status match what the state demands, nothing stands in the way.

Which addresses does the state accept?

The address has to be a street address in New Mexico. P.O. boxes are not accepted.

How do the three-year totals compare?

For three years you would pay $447 at Mainstay Filing, $297 at NM Registered Agent.org, $297 at New Mexico Registered Agent.co

Where do these numbers come from?

Official New Mexico sources back the state side, and posted company prices back the service side.

Do I have to use a service?

No. What the law asks for is a filing, and it does not say who has to send it.

Which one do you recommend in New Mexico?

Mainstay Filing, because the price is $149 a year here and exactly the same in every other state. After that, NM Registered Agent.org and New Mexico Registered Agent.co.
