Best LLC Formation Services in Missouri

Missouri is one of only a handful of states with no annual report requirement. The state's own FAQ answers in one word, no. Illinois bills an LLC $75 every year, and Kansas collects an information report every two years. Missouri never comes back for more.

Missouri allows anonymous LLCs, and you can check that on the state's own form. The Articles of Organization (form LLC-1) have no field for member or manager names, only for an organizer, who does not have to be an owner. Your name stays off the record.

Missouri offers Series LLCs under Section 347.186. One parent, many protected series. That beats paying $50 for each new entity if you hold several rentals or run distinct lines. Two conditions come attached. Your Articles have to give notice of the liability limit. They also have to separately identify each series.

A series does not automatically cost you the anonymity above. Most guides read this wrong. Field 6 of form LLC-1A asks for the series' members or managers only if they differ from the limited liability company. Own every series yourself and the field stays blank. Bring a partner into one series and that series names names.

One date is worth watching. A 2026 amendment to Section 347.186 takes effect on 28 August 2026. It lets a series pull its own certificate of good standing. It also orders the Secretary of State to list every series on the public business search by 31 January 2027, the same way a normal company is listed. The filing stays quiet. The register will not.

Missouri law requires an operating agreement for every LLC (RSMo 347.081). Most states treat the document as optional. Here the statute says shall. A single member company needs it as a written declaration. The state never collects it, the Secretary of State will not even accept one for filing, but a bank opening your business account will ask for it.

1. Adopt your operating agreement first. Missouri law (RSMo 347.081) requires every LLC to have one, and a single member company needs it in writing. Do not mail it to the state. The Secretary of State will not accept it. Keep the signed copy with your records, banks and courts ask for it.
2. Get an EIN from the IRS. You need this federal number to open a business bank account, hire employees, or file taxes. It is free. The IRS website issues it in about five minutes.
3. Register for Missouri taxes if you sell taxable goods. Registration happens at the Missouri Department of Revenue. DOR also issues your state tax ID.
4. Check local license requirements. Missouri has no general state business license. But St. Louis, Kansas City, and Springfield each run their own licensing. Ask your city or county clerk.
5. Skip the federal BOI report. The requirement is dead. Guides written before 2025 told new LLCs to file ownership reports with FinCEN or face fines. FinCEN exempted all US-formed companies on March 26, 2025, and a final rule made that permanent on 14 August 2026. A Missouri LLC formed today files nothing, and anyone charging to file one is selling a dead rule.

• Paper filing costs $105, online costs $50 - The state's own FAQ prices the gap at $55. Every service on this page files online. If you file yourself, use the portal.
• Online filings must be paid by card - The portal takes credit cards only. It adds a 2 percent plus 25 cent convenience fee, so the real online total is $51.25. The state keeps none of it.
• The operating agreement is legally required - RSMo 347.081 mandates one for every Missouri LLC. Free tiers usually leave it out. Then they sell it back as an add-on or a template.
• Name reservation costs $25 and caps at 180 days - A reservation holds your name for 60 days and renews twice. Then the door shuts. The same applicant can never reserve that name again.
