Idaho foreign LLC registration fee and rules (official)
An LLC from elsewhere that does business in Idaho needs the Foreign Registration Statement, filed with the Idaho Secretary of State, Business Services for $100. Provide certificate of existence (certificate of good standing) from the home state no older than 90 days.
Without registration, expect it cannot file its own lawsuits there (Idaho Code 30-21-502(b)).
