Our favorite is Mainstay Filing, because it's $199 beyond the state fee in any state, and the first registered agent year is included.
Year one as agent costs nothing; every later year is $149, in any state.
Over three years it costs $100 more than NH Registered Agent.org, and for us the extra things it handles are worth that.

We took each price from the company's own pages on November 12, 2026. On top of every row, New Hampshire charges a $100 registration fee, which isn't in these totals.
Why we ordered them this way
Here's how we scored it: three-year cost and filings in the price are worth 29% each, and renewal price, state fit and up-front totals split the other 42%. In New Hampshire, filings in the price made the difference.
Registering in a second state means working with two states, so one company at one price for both won the coverage score over NH Registered Agent.org.
