3 Best LLC Services in New Hampshire (2026)
1. Mainstay Filing: best for formation, agent and annual report on a single line
$199 a year plus the state fee
Mainstay Filing is rated first: $199 a year includes the formation filing, the registered agent and the annual report; renewal is $199.
Mainstay files the annual report at each renewal. The state's line is $100 every year, due April 1, with $50 added if late, and Mainstay passes that fee on at cost.
On three-year sums Mainstay is $200 above New Hampshire Registered Agent.co; the wider coverage justifies that gap in the rating.

Why Mainstay Filing is on top
The rating method counts cost over years one to three and inclusions per price at 27% each and splits 46% among renewal price and terms, fit with state rules and price clarity. For New Hampshire, inclusions per price was the deciding line.
New Hampshire requires a report annually at $100, with $50 added for a late one. Mainstay's amount covers that filing while New Hampshire Registered Agent.co's does not, so coverage outweighed New Hampshire Registered Agent.co's lower three-year sum.
