The questions, one by one

Does my LLC need a registered agent here?

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

The law behind it: N.H. RSA 304-C:36. gc.nh.gov, last seen October 2026

Who can I name as my agent?

A New Hampshire resident, or a business entity registered with the Secretary of State, whose office is the registered office.

Qualify, and the job can be yours for free.

What should I budget for an agent?

Prices start at $99 to $149 a year, and three years total $297 to $447.

The state charges the same no matter the agent.

What's the agent there for?

It takes legal documents for your LLC at its New Hampshire address.

If papers arrive and nobody accepts them, a case may move ahead without you. What being served means

Are there yearly charges besides the agent?

Keep the annual report current. You file it every year for $100. The state lists the due date as April 1, so don't let it slide.

More questions

Could I name myself?

Yes, if your address and status fit the state's rule.

What's the address requirement?

The address has to be a physical street address in New Hampshire; filings that list an out-of-state address are not processed. P.O. boxes are not accepted.

After three years, what have I paid?

NH Registered Agent.org will cost you $297, Mainstay Filing will cost you $447, New Hampshire Registered Agent.co will cost you $297

Where did you get these numbers?

New Hampshire's fee schedules and forms for state costs; each company's price page for service costs.

Does the state make me use a service?

No. The state takes filings straight from owners. A service saves you time and can serve as your agent, but nobody makes you hire one.

What's the best registered agent for New Hampshire?

NH Registered Agent.org wins on cost across three years, ahead of Mainstay Filing and New Hampshire Registered Agent.co.
