Our top pick

1. Idaho Registered Agent.co: best for a Idaho LLC that wants to stay close to home

$199 to form, then $99 a year for the agent, plus the state fee

Our mark 9.5 out of 10

Top grade, Idaho Registered Agent.co: $199 for formation plus the state fee, then $99 yearly for the agent.

You get an in-state street address for the registered office, and any papers served on the company are scanned into your online account.

The annual report is not in its published price, so that task stays on your list with Idaho, due every year.

On a three-year bill it comes in under Mainstay Filing, and that is a heavily weighted criterion for us.

  • Formation prepared and filed
  • A first year as your registered agent

Pros

  • Then $99 a year to keep the agent
  • Formation costs $199 before state fees

Our mark 8.8 out of 10

Rounding out the list is Mainstay Filing: the Idaho formation, your registered agent and the annual report are bundled at $199 a year.

The thinking behind the order

Two criteria weigh 26% each in these grades: cost to launch and stay and launch paperwork handled. Renewal behavior, state match and price transparency share 48%, and Idaho turned on cost to launch and stay.

Idaho Registered Agent.co comes to $397 over three years, $200 under Mainstay Filing. Mainstay would file the annual report too, but an owner can handle it alone at no cost, so the lower price took this page.

Every criterion and weight is listed on How we rank.
