Mainstay Filing takes the top spot because the Idaho formation, a registered agent and the annual report share a single $199 price.
Renewal includes Mainstay filing the annual report on your behalf. Idaho takes no state fee for it, due last day of the entity's anniversary month, and Mainstay passes that fee through at cost.
Its three-year total is $200 above ID Registered Agent.org's, and what the price covers justifies that gap for us.

The 3 picks side by side
Each number out of 10 is our own mark, drawn from the weighted criteria on How we rank, and not a customer rating.
Idaho LLC service pricing in 2026: first year, renewals, three-year total
Every price comes from the company's own pages as of November 12, 2026. The $100 Idaho filing fee comes on top of each row and is left out of the totals.
Why these made the shortlist
Filing Shortlist puts 28% of the weight on three-year price and 28% on what the price covers. The remaining 44% goes to renewal terms, fit for the state and price clarity, and for Idaho the deciding factor was what the price covers.
Idaho asks for a report each year. Mainstay's price covers that filing and ID Registered Agent.org's does not, so coverage beat ID Registered Agent.org's lower three-year bill.
Every criterion and weight is set out on How we rank.
