The Idaho entry filing for LLCs formed elsewhere

Entry costs $100, paid when the Foreign Registration Statement reaches the Idaho Secretary of State, Business Services. Alongside it, the state wants certificate of existence (certificate of good standing) from the home state, issued inside the last 90 days.

From then on it handles the annual report, before the end of the month in which the LLC registered.

Checklist before the crossing

  • Certificate of existence (certificate of good standing) from the home state, at most 90 days.
  • Exact legal name and formation date from the home state.
  • A registered agent with a street address here; every provider on this route can supply one.
  • A budget for the $100 state fee.

Working without registration: the risks

The state's courts turn back a suit from an LLC that has not registered (Idaho Code 30-21-502(b)). Agreements it has already signed keep their force (Idaho Code 30-21-502(c)).

Why Mainstay Filing leads the route

Mainstay Filing pulled ahead of ID Registered Agent.org on steps the service takes over, weighted 27%.

A foreign LLC lives in two states, and reach settled the order.
