Our top choice
1. Mainstay Filing: best for owners who may add a state later
$149 annually (renewal price $149)
Why Mainstay Filing is first: one $149 agent plan that moves with you whenever you add a state.
Over three years you would pay $150 more than you would with ID Registered Agent.org. Coverage is 26% of the score, though, and handling more filings outweighs that difference.

How Idaho compares with the states near it in the ranking
Idaho registered agent requirements, as the law states them
Every LLC must name a registered agent with an in-state street address. The address has to be a physical street address in Idaho. P.O. boxes and commercial mailboxes are not accepted.
You may choose: An Idaho resident, or a business entity authorized to do business in Idaho. An assumed business name (DBA) cannot serve. The law is Idaho Code § 30-21-404.
Keeping your Idaho LLC active in 2026
Your annual report is due every year (last day of the entity's anniversary month). The state mails its notices to your registered agent.
Why the Idaho list is in this order
Upkeep the price covers decided first place in Idaho. It is 26% of the score, and the other criteria are price over three years, renewal terms, fit with the state, plain statement of the state fee.
Because it works in every state, it outscored ID Registered Agent.org, even though ID Registered Agent.org costs less.
