Every New Mexico LLC must keep a registered office and a registered agent in the state. The agent can be a New Mexico resident or a business with a New Mexico place of business that matches the registered office. Changing your registered agent costs $20 under New Mexico law as of October 2026, filed online with the Secretary of State. Our recommendation is Mainstay Filing at $149 a year; NM Registered Agent.org is a lower-priced alternative.

How much does it cost to change a registered agent in New Mexico?
New Mexico sets the fee in statute. NMSA 1978, section 53-19-63, charges $20 for filing a statement of change of the registered office, the registered agent, or both, as of October 2026. If the agent itself files to report a change, the fee is also $20.
Here is how that fits with the rest of New Mexico’s LLC costs:
| New Mexico LLC item | Rule or state fee (October 2026) |
|---|---|
| Statement of change of registered office or agent | $20 |
| Articles of organization | $50 |
| Annual report | None required for LLCs |
| How filings are made | Online only, through the Secretary of State’s business portal |
| Who can be the agent | A New Mexico resident, or a domestic or authorized foreign business whose New Mexico place of business is the registered office |
Because New Mexico has no LLC annual report, there is no yearly filing that nudges you to review your agent. That makes it easy for an outdated agent to sit on the record for years. Mainstay’s New Mexico LLC cost guide covers the full set of state and service costs.
Who can serve as a registered agent in New Mexico?
Under NMSA 1978, section 53-19-5, an LLC must continuously maintain a registered office in New Mexico, which may be the same as its principal place of business, and a registered agent who is one of the following:
- An individual who resides in New Mexico
- A domestic corporation, LLC or partnership whose place of business in New Mexico is the same as the registered office
- A foreign corporation, LLC or partnership authorized to transact business in New Mexico, with a New Mexico place of business that is the same as the registered office
The point of the “same as the registered office” rule is simple: the agent has to actually be where the state and process servers expect to find it. Filings that change the office or agent state the new street address.
Agent acceptance The Secretary of State posts a Registered Agent Statement of Acceptance form among its business resources. Get your new agent’s written agreement before you file, so the appointment is not challenged later.
What does a registered agent do for a New Mexico LLC?
The registered agent is the official address for service of process. A summons in a lawsuit, a subpoena or a formal notice from a state agency is delivered there, and the agent forwards it to the owners.
New Mexico’s light ongoing compliance can lull owners into forgetting about the agent entirely. With no annual report and no franchise tax filing at the Secretary of State, years can pass between filings. If your agent moves, retires or closes during that time, legal papers may go to an address nobody checks. A dependable agent, and an occasional look at your public record, prevent that.
Can you be your own registered agent in New Mexico?
Yes, if you live in New Mexico. You would be the individual registered agent, and your New Mexico address would be the registered office.
The trade-offs to weigh:
- Cost: no service fee.
- Privacy: your name and address are part of the public business record.
- Availability: you need to be reachable at that address to accept legal papers.
- Out-of-state owners: if you live in Texas, Arizona, Colorado or anywhere else, you cannot serve personally and need a New Mexico resident or a qualifying business.

How to choose a New Mexico registered agent
Most registered agent services perform the same legal function, so compare them on the details that affect you:
- A staffed New Mexico address. The statute ties the agent to a real place of business in the state. A forwarding mailbox does not meet that standard.
- How you hear about service. Ask how quickly documents are scanned or sent, and whether you can see them in an online account.
- Year-two pricing. A low first-year price can rise at renewal, which matters more in a state where the agent fee is your main recurring cost.
- Help with the switch. Some providers file the $20 statement of change for you; others leave it to you.
- Multi-state coverage. If you also register in Texas, Arizona or Colorado, one provider can keep all your notices in one place.

FAQs
Is a registered agent required for a New Mexico LLC?
Yes. NMSA 1978, section 53-19-5, requires every New Mexico LLC to continuously maintain a registered office and a registered agent in the state. The agent must be a New Mexico resident or a domestic or authorized foreign business whose New Mexico place of business is the same as the registered office.
How much does it cost to change a registered agent in New Mexico?
New Mexico’s LLC Act sets the fee for a statement of change of registered office or registered agent, or both, at $20 as of October 2026 (NMSA 1978, section 53-19-63). The filing is made online through the Secretary of State’s business portal, since paper filings are no longer accepted.
Does New Mexico require an annual report for LLCs?
No. New Mexico does not require LLCs to file an annual report with the Secretary of State, which keeps ongoing costs low. The flip side is that there is no yearly prompt to review your registered agent, so it is worth checking your public record periodically and filing a $20 change when needed.
Can I be my own registered agent in New Mexico?
Yes, if you reside in New Mexico. You would serve as the individual registered agent, and your New Mexico address would become the registered office in the public record. If you live in another state, you need a New Mexico resident or a qualifying business entity with a New Mexico place of business.
Can I file a New Mexico registered agent change on paper?
No. The New Mexico Secretary of State has moved all business filings online and no longer accepts paper filings for business applications. You file the statement of change through the online portal after creating an account, then find the form under the Forms tab of your dashboard.
What is the Registered Agent Statement of Acceptance in New Mexico?
It is a form the New Mexico Secretary of State provides among its business resources, which a registered agent signs to confirm it accepts the appointment. Having the new agent sign one before you file a change documents its consent and avoids disputes about whether it agreed to serve.
What does a New Mexico registered agent service cost?
Service companies set their own prices. Mainstay Filing, our top recommendation, costs $149 a year and renews at $149, with the switch included. NM Registered Agent.org costs $99 a year. The state’s own charge is the $20 statement of change, and New Mexico has no annual report fee for LLCs.
