The key questions

How much money do I need to set aside?

On your own it is $100. With a service, it is $199 more.

Total the state's fees from filing through year three: $300. official source gc.nh.gov (October 2026) to check

What exactly do I submit?

Can the LLC go without a registered agent?

Every LLC must name a registered agent with an in-state street address.

What does upkeep involve?

Expect the annual report to come back every year, at $100 each time. In the state's words it is due April 1, so mark the date.

official source sos.nh.gov (August 2026) to check

Is it possible to do this without a service?

Nothing stops you from filing yourself. Then your three-year cost is $300 in state fees.

Choosing a service raises your three-year cost by $397 to $597.

Why is number one first?

Mainstay Filing is strongest on filing jobs included, and that decides it.

The two heavy checks are total for three years (37%) and filing jobs included (27%); three lighter checks follow.

Not having to file the annual report is worth more to us than a small saving.
