What you probably want to know

How much should I set aside to form it?

The state fee is $100. Hire a service and add $199.

Add the state's fees from filing through year three: $300. gc.nh.gov, confirmed October 2026 (official)

What goes to the state to form the LLC?

You send the Certificate of Formation of a New Hampshire Limited Liability Company (Form LLC-1) to the New Hampshire Secretary of State, and that single filing starts your LLC.

gc.nh.gov, confirmed October 2026 (official)

Is a registered agent a legal requirement?

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

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

gc.nh.gov, confirmed October 2026 (official)

What does it cost to keep an LLC going?

Mostly the annual report, once a year, at $100. The state's due date: April 1. Jot that down early.

A late filing adds $50 to the bill.

sos.nh.gov, confirmed August 2026 (official)

Could I file this on my own?

Nothing stops you from filing yourself, and then the three-year bill is $300 in state fees.

Expect $397 to $597 over three years if you hire.

What put number one on top?

It comes down to work taken off your hands, and Mainstay Filing is best at it.

Five checks set the order: cost across three years (33%), work taken off your hands (31%), prices stated clearly (14%), renewal price (12%) and where it works (10%).

New Hampshire Registered Agent.co has the lower bill, but the annual report is still your job there.
