No.1
Our top pick in Idaho
1. Idaho Registered Agent.co: best for an Idaho LLC that intends to stay put
$199 to form, then $99 a year for the agent, with the state fee extra
Score9.5out of 10
First place: Idaho Registered Agent.co. Idaho formation costs $199 beyond the state's fee, with the registered agent free the first year, and $99 yearly keeps the agent.
An in-state street address serves as the registered office, and papers served on the company are scanned into your online account.
The annual report lies outside its published prices, so you file it with Idaho every year.
Over three years it costs less than Mainstay Filing, and cost is one of our two most heavily weighted criteria.

What decided the order
Two criteria carry 31% each in this ranking, charge over three years and work taken off the founder. Renewal conduct, fit with local rules and pricing in plain sight share 38%, and in Idaho the decisive one was charge over three years.
Over three years Idaho Registered Agent.co totals $397, $200 less than Mainstay Filing. Mainstay would file the annual report as well, yet an owner can do it alone at no cost, so the lower charge carried the ruling.
Each criterion and its weight appear on How we rank.
