Every New Hampshire LLC must keep a registered agent at a physical New Hampshire street address, and the agent’s office must be the same as the company’s registered office. The agent can be a New Hampshire resident or a qualifying corporation, LLC or LLP. Changing your registered agent with Form 10 costs $15 as of October 2026 (plus a $2 handling charge if you pay online). We recommend Mainstay Filing at $149 a year, and NH Registered Agent.org is a lower-cost alternative.

Who can be a registered agent in New Hampshire?
New Hampshire’s LLC statute gives a precise list. Under RSA 304-C:36, the registered agent must be one of the following:
- An individual who resides in New Hampshire, whose residential or business office is the same as the registered office
- A corporation organized or authorized under New Hampshire’s business, nonprofit or professional corporation laws
- A limited liability company formed or authorized under New Hampshire law, including a professional LLC
- A limited liability partnership registered in New Hampshire
For the entity options, the agent’s business office must be identical with your registered office. In other words, the registered office is simply wherever your agent actually works.
The address rule The registered office has to be a physical street address in New Hampshire. The instructions for the LLC formation form are blunt: a street address must be provided, and an application listing an out-of-state address will not be processed. A P.O. box cannot serve as the registered office, although the company can use one as its separate mailing address.
What does a New Hampshire registered agent do?
The registered agent receives service of process and official notices for your LLC. If the company is sued, the summons is delivered to the agent at the registered office, and the agent sends it to you.
That role sounds administrative, and it is, but the stakes are real. Court deadlines generally run from delivery, so papers that sit unopened at an old address can turn into a default judgment. The agent’s job is to be at a known New Hampshire address during business hours and pass on what arrives without delay.
When you compare services, three questions do most of the work. Does the provider have its own staffed New Hampshire office rather than a mail drop? How will you learn that something was served, and how quickly can you see it? And will the price you pay in year one still apply at renewal?
Can you be your own registered agent in New Hampshire?
If you live in New Hampshire, yes. You would be listed as the agent, and your home or business office would become the registered office.
Before you do that, consider:
- Residency: owners living across the border in Massachusetts, Maine or Vermont are not eligible personally.
- Privacy: the registered office address appears in the public business record.
- Availability: someone needs to be reachable at that address to accept papers.
- Moves: every time your office changes, you will need a $15 Form 10 filing.
How much does it cost to change a registered agent in New Hampshire?
The Statement of Change of Registered Office or Registered Agent, or Both (Form 10) carries a $15 filing fee under RSA 304-C:191 as of October 2026. If you pay electronically, New Hampshire adds a separate $2 handling charge, so the online total is $17.
Form 10 is the only route. The annual report reviews your registered agent information but is not how you change it; agent changes require the separate statement.
For the other recurring costs, including the $100 annual report, see Mainstay’s New Hampshire LLC cost guide.
Steps to change your New Hampshire registered agent
- Pick a new agent who qualifies under RSA 304-C:36 and confirm its New Hampshire street address.
- Complete Form 10, Statement of Change of Registered Office or Registered Agent, or Both. It is a multi-entity form used by corporations, LLCs and LLPs.
- Enter the new registered office address and the new agent’s name.
- File it with the Secretary of State’s Corporation Division, on paper or through the state’s QuickStart online system, and pay the $15 fee (plus $2 online).
- Search the New Hampshire business records to confirm the change.
New Hampshire annual reports
Every New Hampshire LLC files an annual report between January 1 and April 1, starting the year after it forms (a company formed between December 1 and April 1 skips that first year). The fee is $100, or $102 online, and a $50 late fee applies after April 1. The information must be current as of January 1.
Reports are filed through NH QuickStart, which also offers a one-click option when nothing has changed. A domestic LLC that keeps missing reports faces administrative dissolution after roughly two years of non-filing.

FAQs
Is a registered agent required for a New Hampshire LLC?
Yes. RSA 304-C:36 requires every New Hampshire LLC to maintain a registered office and a registered agent in the state. The registered office must be a physical New Hampshire street address that matches the agent’s residential or business office. Applications listing an out-of-state address are not processed.
How much does it cost to change a registered agent in New Hampshire?
Form 10, the Statement of Change of Registered Office or Registered Agent, or Both, has a $15 filing fee under RSA 304-C:191 as of October 2026. Paying electronically adds a $2 handling charge, for $17 online. The annual report is not used to change an agent; Form 10 is a separate filing.
Can I be my own registered agent in New Hampshire?
Yes, if you reside in New Hampshire and your home or business office serves as the registered office. That address becomes public, and you need to be available to receive legal papers there. Owners who live in Massachusetts, Maine or other states must appoint a New Hampshire resident or a qualifying business entity.
Can a New Hampshire registered office be a P.O. box?
No. The registered office must be a physical street address in New Hampshire, and the formation form instructions warn that applications with an out-of-state address will not be processed. A P.O. box can be listed as the company’s mailing address, but not as the registered office.
When is the New Hampshire LLC annual report due?
New Hampshire LLCs file between January 1 and April 1 each year, beginning the year after formation, with information current as of January 1. The fee is $100 ($102 online), and a $50 late fee applies after April 1. Reports are filed through NH QuickStart.
What happens if a New Hampshire LLC stops filing annual reports?
Late reports pick up a $50 late fee, and a domestic LLC that fails to file for about two years in a row faces administrative dissolution under RSA 304-C:136. Foreign LLCs registered in New Hampshire risk revocation of their registration sooner, after the end of the year of non-filing.
Is New Hampshire registered agent service expensive?
Not necessarily. Mainstay Filing, the service we recommend first, costs $149 a year and keeps renewals at $149, including the switch from your current agent. NH Registered Agent.org costs $99 a year. On top of that, New Hampshire charges $15 for the Form 10 change filing.
