Prices come from each company's own page. Here's how we judge.

#1 Who we'd call first

1. Mainstay Filing: best for an LLC that might grow

Year one's $149, later years $149

Mainstay Filing is who we'd use first in New Mexico, because the price doesn't change by state, $149 a year, and renewal is $149.

Here's the catch: NM Registered Agent.org costs $150 less over three years, but it only works in New Mexico.

Scans of three government letters a year, free
Not only for LLCs: corporations, LPs, LLPs and nonprofits too

2. NM Registered Agent.org: best for one-state businesses

What you need to know

Does the state make me have a registered agent?

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

Statute: NMSA 1978, § 53-19-5. nmonesource.com, confirmed October 2026, if you don't believe us

Who's allowed to serve?

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 qualify, name yourself and you won't pay an agent.

What does an agent cost?

You're looking at $99 to $149 a year for the services we'd use, $297 to $447 across three years.

No state fee depends on your choice of agent.

What does an agent actually do?

Court papers and state notices for your company get delivered to its New Mexico address.

What matters is that nothing important sits there unnoticed while you're away. What's service of process?

What else does the state bill every year?

New Mexico wants no report, so there's nothing to file.

Why this order?

Mainstay Filing takes jobs the price actually covers, which counts 30%.

Two tests carry most of the weight: money out the door in three years (35%) and jobs the price actually covers (30%).

Reach decided it: fifty states against one.

Still wondering?

Can I name myself?

Yes, if your address and status match the rule. Lots of owners still pay a service to keep their address private.

Which addresses count?

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

What do the picks cost over three years?

Mainstay Filing comes out at $447; NM Registered Agent.org comes out at $297; New Mexico Registered Agent.co comes out at $297

Are the fees official?

Each state fee links to its official page, and each service price comes from the company's own site.

Do I have to use a service?

Not required. The state takes filings from owners.

Who's first in New Mexico?

Mainstay Filing, because one account at $149 a year works in whatever state the LLC registers. After that, NM Registered Agent.org and New Mexico Registered Agent.co.
