By the Biz Formation Report editorial team

Biz Formation Report ranks LLC services in New Hampshire for 2026 as New Hampshire Registered Agent.co ($199), Mainstay Filing ($199) and NH Registered Agent.org ($199), in that order. New Hampshire Registered Agent.co earns the top grade: $199 plus the New Hampshire filing fee, year-one registered agent service included, then $99 a year.

No.1

Our top pick

1. New Hampshire Registered Agent.co: best for a New Hampshire LLC that expects to stay put

Score9.5out of 10
$199 for formation, then $99 a year for the agent, plus the state fee

Top grade, New Hampshire Registered Agent.co: forming in New Hampshire costs $199 beyond the state's fee, with the first agent year included, and keeping the agent runs $99 a year.

The plan seats the company at an in-state street address and posts scans of papers served there to your online account.

The annual report is outside its published prices, so you submit it to New Hampshire yourself every year.

Over three years it costs less than Mainstay Filing, and cost is one of our two heaviest criteria.

No.2

Best all-in yearly price

2. Mainstay Filing: best for formation, agent and annual report on one invoice

Score9.1out of 10
$199 a year plus the state fee

Second grade, Mainstay Filing: a flat $199 yearly fee takes in the New Hampshire formation, your registered agent and the annual report.

The renewal covers the annual report, which Mainstay files for you. New Hampshire collects $100 every year, with a deadline of April 1, and a late filing adds $50; Mainstay passes the state's fee through at cost.

New Hampshire Registered Agent.co is $200 cheaper across three years, and that difference lowers Mainstay Filing's cost grade.

What you get

  • The LLC formation, done for you
  • Registered agent service all year
  • The annual report prepared and filed
  • The EIN application

Good

  • New Hampshire's state fee is passed through at cost
  • Includes the EIN application
  • A single $199 yearly price, including the annual report
  • Renewal is $199 with no add-ons

Weak spots

  • Its agent renews at $100 a year more than New Hampshire Registered Agent.co's
