Idaho filing for out-of-state LLCs

An outside LLC registers by sending the Foreign Registration Statement and $100 to the Idaho Secretary of State, Business Services. The state wants certificate of existence (certificate of good standing) from the home state, dated within 90 days.

  • Exact legal name and formation date, home state.
  • A registered agent in the state, supplied by every pick.
  • Payment of the $100 filing fee.
