Pros

The thinking behind the order

At Launchwise Review, cost to launch and stay and launch paperwork handled each count for 26% of a grade, and renewal behavior, state match and price transparency split the remaining 48%. In New Hampshire, cost to launch and stay made the call.

New Hampshire Registered Agent.co comes to $297 over three years, $150 under Mainstay Filing. A launch that only needs an agent in New Hampshire gets little from fifty-state reach, so the lower yearly price took it.

Every criterion and weight is listed on How we rank.

Yes. Put a registered agent with a physical New Hampshire address on the paperwork, because the state will not accept an LLC without one.

What should I budget each year for a New Hampshire registered agent?

Expect $99 to $149 a year, and each company keeps its price at renewal.
