Who we recommend in New Hampshire
The order comes from our method: three-year cost first, then how much work the price covers.1. Mainstay Filing: best for growing companies
$199 up front, $149 annually after that
The reason Mainstay Filing leads here is that registering costs $199 plus state fees, and the registered agent is free the first year.
Yes, NH Registered Agent.org comes in $100 lower across three years. We still lead with the one that covers all states.
After the free year, the registered agent renews at $149 a year in any state.
Includes
- Out-of-state registration handled
- Registered agent, no charge in the first year
- The same fee in every state
Points in its favor

Where it falls short
- Renewal runs $50 over NH Registered Agent.org
2. NH Registered Agent.org: best for registering in this state only
$199 up front, $99 annually after that

- A first year of agent service
Points in its favor

The questions, one by one
When must an out-of-state LLC register here?
Registration comes first: an LLC from another state signs up before transacting business in New Hampshire.
An unregistered LLC may face back fees covering the unregistered time.
gc.nh.gov, confirmed October 2026
How much does registration cost?
$100 goes to the state, plus $199 if a service handles it.
By the end of year three the state has collected $300. sos.nh.gov, confirmed October 2026
What is the application called?
You file the Application for Registration as a Foreign Limited Liability Company (Form FLLC-1) with the New Hampshire Secretary of State, Corporation Division, and that is all.
A certificate from your home state is not part of this filing.
Is there a recurring filing?
Annual report: $100.
The schedule reads April 1.
Why is the first pick first?
It is how much work the price handles, weighted at 28%, that puts Mainstay Filing first.
What three years cost carries 34% and how much work the price handles carries 28%. Three smaller criteria decide close calls.
The home state needs an agent as well, and one account for both is simpler.
