New Hampshire: our ranking
The order comes from our five tests: three-year cost first, then what the price covers.
#1Our top pick
1. Mainstay Filing: best for adding states down the road
$199 to register, $149 a year for the agent after
There's one fee, $199, whatever state you're registering in, and the registered agent is waived for the first year. That's why Mainstay Filing is first.
Here's the catch: NH Registered Agent.org costs $100 less over three years, but it only works in New Hampshire.
Year one of the registered agent is on the house; every renewal after that is $149.

Which form, and who gets it?
The form's the Application for Registration as a Foreign Limited Liability Company (Form FLLC-1), and the New Hampshire Secretary of State, Corporation Division gets it.
You don't need a good standing certificate from home.
What do I owe once I'm registered?
The state wants a annual report later, and it's $100.
Per the state, it's due April 1.
What put number one on top?
Mainstay Filing scores best on jobs the price actually covers, and that test is worth 30%.
We run five tests: money out the door in three years (35%), jobs the price actually covers (30%), no hunting for the price (14%), no surprise at renewal (11%) and where it works (10%).
With two states in play, a provider that covers every state beat NH Registered Agent.org.
The last row is our math, not the state's: filing fee, plus the reports in years two and three, plus any minimum tax. If a cost has no fixed amount, like a newspaper notice, it's explained above and left out.
More questions
Does my home state need its own agent?
Yes. Your home state has its own agent rule, and Mainstay Filing can cover both states from one account.
What's the three-year damage for each?
Over three years you're looking at $497 at Mainstay Filing, $397 at NH Registered Agent.org, $397 at New Hampshire Registered Agent.co, with state fees on top.
Where do these numbers come from?
Official New Hampshire sources back the state side, and posted prices back the service side.
Do I have to use a service?
Not required. The state takes filings from owners.
Will a service file it for me?
All of them do, so the service fee's the only difference.
What's the best foreign registration service in New Hampshire?
Mainstay Filing is first: New Hampshire's fee plus $199 gets you registered, and nobody bills you for the registered agent until year two. Then comes NH Registered Agent.org and New Hampshire Registered Agent.co.
