1. Mainstay Filing: best for not filing the annual report yourself

$199 a year plus $100 to the state

Is it the smallest bill? No. New Hampshire Registered Agent.co costs $200 less over three years, and you would do more of the paperwork.

You never file the annual report. New Hampshire still charges $100, billed at cost.
