More questions
Can I be my own agent?
Yes, if your address and status match the rule. Lots of owners still pay a service to keep their address private.
What address does an agent need?
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.
What do the picks cost over three years?
Over three years you're looking at $297 at NH Registered Agent.org, $447 at Mainstay Filing, $297 at New Hampshire Registered Agent.co
Where do these numbers come from?
Official New Hampshire sources back the state side, and posted prices back the service side.
Is a service required?
No. You can file with the state yourself. A service saves you time and can be your agent, but nothing makes you hire one.
Who's first in New Hampshire?
Go with NH Registered Agent.org first, then look at Mainstay Filing and New Hampshire Registered Agent.co.
