1. Mainstay Filing: best for formation, agent and annual report in a single price

$199 a year plus the state fee

Editorial score 9.4 out of 10

The desk picks Mainstay Filing: one $199 yearly bill covers the New Hampshire formation filing, the registered agent and the annual report.

Mainstay files the annual report for you when you renew. New Hampshire wants $100 every year, by April 1, and a late filing tacks on $50; Mainstay hands the state's fee through at cost.

Over three years Mainstay runs $200 more than NH Registered Agent.org, and the desk thinks the wider coverage is worth it.

Every price here was read off the company's own pages on November 12, 2026. New Hampshire's $100 filing fee comes on top of every row and is left out of these totals.

How the desk made the call

Here is the weighting: 33% for spend over three years, 33% for work the price removes, 34% spread over what renewal looks like, fit with the state and plain price display. In New Hampshire, work the price removes made the call.

New Hampshire wants a report each year and charges $100, plus $50 if you are late. Mainstay's price covers that filing and NH Registered Agent.org's does not, and that outweighed NH Registered Agent.org's lower three-year cost.

The full criteria and weights are on How we rank.
