Idaho law on a registered agent
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.
Permitted agents: An Idaho resident, or a business entity authorized to do business in Idaho. An assumed business name (DBA) cannot serve. The authority is Idaho Code § 30-21-404.
Each year's state fees for a Idaho LLC
Each year the annual report costs nothing, last day of the entity's anniversary month. The state sends its mail to your registered agent.
Why Mainstay Filing is first
Mainstay Filing wins on paperwork inside the price, which counts for 28%, and ID Registered Agent.org follows.
One agent for any state beat the single-state option.
