Idaho foreign registration: fee, form, office

$100 goes to the Idaho Secretary of State, Business Services with the Foreign Registration Statement. Attach certificate of existence (certificate of good standing) from the home state, issued within 90 days.

Recurring filing: annual report, before the end of the month in which the LLC registered.

What to have ready

  • Certificate of existence (certificate of good standing) from the home state, at most 90 days.
  • The registered name and formation date from home.
  • Someone to serve as registered agent in Idaho.
  • Payment of the $100 filing fee.

If you skip registration

Lawsuits it tries to bring are blocked until the registration is on file (Idaho Code 30-21-502(b)). Its contracts remain valid (Idaho Code 30-21-502(c)).

Why Mainstay Filing is first

Deciding factor in Idaho: state filings covered (30%). Mainstay Filing beat ID Registered Agent.org on it.

A company registering in Idaho already has a home state, and covering both with one provider scored highest.
