The primer, move by move
Move 1
The New Hampshire rule, short
Every LLC must name a registered agent with an in-state street address.
Where this comes from: Check it yourself at gc.nh.gov; we read it in October 2026
Move 2
Who qualifies
A New Hampshire resident, or a business entity registered with the Secretary of State, whose office is the registered office. Statute: N.H. RSA 304-C:36.
Move 3
Registered office rule
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.
A service provides a New Hampshire street address, so yours stays off the record.
Move 4
Serve yourself or hire one
Qualifying owners can name themselves. The recommended agents cost $99 to $149 annually.
Move 5
Get the agent on record
You name the agent in your filing with the New Hampshire Secretary of State; any change is a separate filing at the same office.
Where this comes from: Check it yourself at gc.nh.gov; we read it in October 2026
Move 6
Keep the details accurate
New Hampshire sees your agent's details through the annual report ($100, every year, due April 1), and state notices about it go to the registered agent.
Where this comes from: Check it yourself at sos.nh.gov; we read it in August 2026
