Missouri checklist

  1. File the formation document. Articles of Organization (LLC-1), Missouri Secretary of State, $50.
  2. Name a registered agent. Required. A Missouri resident, or a corporation authorized in Missouri, whose business office is the registered office.
  3. Get an EIN. Free from the IRS online.
  4. Check licenses. We could not confirm a general-license statement from Missouri’s own pages, so check with your city or county. The state’s starting-a-business page is a good place to begin.
