Number one here

1. Mainstay Filing: best for all fifty states

$149 a year, flat

Our mark 9.5 out of 10

Top grade, Mainstay Filing: the price stays $149 a year if you stay put or expand, and your first three government letters each year are scanned free.

It runs $150 above NM Registered Agent.org across three years; the extra paperwork it handles is worth that to us.

In the price

  • A registered office street address in any state you need
  • Free scan of served papers the same business day they arrive
  • Your first three government letters each year, scanned free
  • Compliance reminders

Pros

  • Works for LLCs, corporations, LPs, LLPs and nonprofits
  • Your first three government letters each year are scanned free
  • $149 a year and it does not rise
  • Papers served on the company are scanned the same business day, free

Less good

  • The agent plan alone costs $50 a year more than NM Registered Agent.org
  • Report filing belongs to the formation package, not the agent plan

How we graded this list

Two criteria weigh 26% each in these grades: cost to launch and stay and launch paperwork handled. Renewal behavior, state match and price transparency share 48%, and New Mexico turned on launch paperwork handled.

Mainstay's plan covers more ground: papers served on the company are scanned the same business day at no charge, the price is the same in all fifty states, and three government letters a year are scanned free. NM Registered Agent.org costs less, and the grades are close.

Every criterion and weight is listed on How we rank.

New Mexico registered agent rules, straight from New Mexico Secretary of State

Every LLC must name a registered agent with an in-state street address. The address has to be a street address in New Mexico. P.O. boxes are not accepted. Law behind it: NMSA 1978, § 53-19-5.

What is left to do in New Mexico once an agent is named

There is no yearly LLC report in New Mexico. The one standing task is to keep a registered agent on file, since the state mails its notices there.

Quick answers about New Mexico registered agents

Do I have to line up a registered agent before launching a New Mexico LLC?

Yes. Put a registered agent with a physical New Mexico address on the paperwork, because the state will not accept an LLC without one.

What should I budget each year for a New Mexico registered agent?

Expect $99 to $149 a year, and each company keeps its price at renewal.

Could I just serve as my own registered agent?

Often yes, if you meet the state's conditions. 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.

Which registered agents are graded on this page?

Mainstay Filing ($149 a year), NM Registered Agent.org ($99 a year) and New Mexico Registered Agent.co ($99 a year), top grade first.

What does a registered agent handle?

Think of the registered agent as the company's mailing address for the state and the courts: lawsuits, subpoenas and official notices land there first. The agent passes them to you, and every plan on this page uploads scans to your account.

Which New Mexico registered agent should a new company pick first?

Mainstay Filing, because $149 a year, still $149 at renewal, and papers served on the company are scanned the same business day at no charge.
