New Hampshire: our picks

Our order, explained on how we choose.
1First choice

1. Mainstay Filing: best for owners who want the upkeep handled

Annual price $199, renewal price $199, state fee extra

First choice: Mainstay Filing. The reason is simple: one yearly price of $199 covers the filing, the registered agent and each annual report.

It costs $200 more than New Hampshire Registered Agent.co over three years, and for that you hand off more of the paperwork.

The annual report is part of the service; New Hampshire still charges $100, billed at cost.

The price covers

  • The formation filing
  • Registered agent for the full year
  • Annual report taken care of
  • Help getting the EIN
  • Official fee, no markup

Upsides

Your questions

What does it cost to form an LLC here?

Budget $100 for the state and $199 for a service.

Counting the recurring report, the state's own fees reach $300 by the end of year three. gc.nh.gov, confirmed October 2026

Who receives the filing?

Just one document creates the LLC: the Certificate of Formation of a New Hampshire Limited Liability Company (Form LLC-1), submitted to the New Hampshire Secretary of State.

gc.nh.gov, confirmed October 2026

Do I have to name a registered agent?

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

What recurs after formation?

One recurring filing: the annual report ($100, yearly). It falls due April 1.

Filing late costs $50.

sos.nh.gov, confirmed August 2026

Can I skip the service?

You can. Without a service you pay just the state: $300 across three years.

A service adds $397 to $597 over three years for doing the filings and, with Mainstay Filing, the reports.

Why these three?

It comes down to what the price takes off your plate, where Mainstay Filing is strongest.

Most of our weighting sits on three-year cost and what the price takes off your plate.

We value a filed annual report over a few dollars saved, so the bundle comes first.
