5Maintain a Idaho Registered Agent

Maintain a registered agent that has a street address in Idaho. The registered agent is responsible for receiving legal documents such as service of process. Appointing a registered agent service is often preferable to listing an officer or director, as their information often changes. Consider using our registered agent service in Post Falls , ID to maintain compliance with the state requirement.
