What you need to register: the Foreign Registration Statement, the Idaho Secretary of State, Business Services, $100. The filing needs certificate of existence (certificate of good standing) from the home state no older than 90 days.
An unregistered LLC can face Idaho courts dismissing your own claims (Idaho Code 30-21-502(b)).
