Opening in Mississippi as a foreign LLC: fee, form and office

Your registration goes to the Mississippi Secretary of State, Business Services, on the Application for Registration of Foreign Limited Liability Company (Filing F0200). Budget $250 for the state.

  • Certificate of good standing or existence, issued within 180 days of your filing date.
  • Your company's exact legal name and the date it was formed at home.
  • A registered agent with a street address in the state; every company graded on this page can serve.
