How to Form an LLC
in Missouri

Missouri charges $50 for Articles of Organization filed online through the Secretary of State Business Services Division at sos.mo.gov/business. Paper filings cost $105 — nearly every competitor article quotes the paper-filing rate as the default, but online is the correct path and more than half the cost. Missouri's $50 online rate is tied for among the five cheapest formation fees in the US (Kentucky $40, Arkansas $45, Colorado $50, Michigan $50, Missouri $50, New Mexico $50, Arizona $50). What makes Missouri genuinely cheapest over the lifetime of an LLC is what happens AFTER formation: Missouri is one of only five US states with NO annual report filing and NO annual fee for LLCs. Once your LLC is formed, the ongoing state-level compliance cost is literally $0/yr for the life of the entity (the other four are Arizona, New Mexico, Ohio, and South Carolina). Missouri also permanently eliminated its corporate franchise tax effective January 1, 2016 under HB 184 (2015), so there is no recurring corporate-level state tax on LLC assets either. Optional extras: name reservation ($25 for 60 days, RSMo § 347.020), certified copies ($10 per document), Good Standing certificate ($10). Eleet AI charges $199 all-inclusive — that covers the $50 state fee, Articles of Organization preparation, filing with the Missouri Secretary of State, and first-year Missouri registered agent service. DIY totals typically land $150–$450+ once you add a commercial registered agent ($100–$299/yr), the state fee, and your time.

Correct — Missouri has NO annual report requirement and NO annual fee for LLCs. You file the Articles of Organization once at formation, pay the $50 online filing fee, and that is the end of your Missouri-side recurring compliance obligations. The Missouri Secretary of State does not require any annual filing, periodic report, biennial statement, or recurring fee to keep a domestic LLC in good standing. Missouri is one of only five US states where LLCs have zero recurring state-level compliance fee — alongside Arizona, New Mexico, Ohio, and South Carolina. (Alabama is close but charges a $100 minimum Business Privilege Tax annually, so its effective recurring fee is $100/yr.) Missouri also permanently eliminated the corporate franchise tax in 2016 under HB 184 (2015) — previously the state levied $0.33 per $1,000 of assets above $10M with a $150 minimum; now zero across the board for all entities. Compare Delaware $300/yr franchise tax, California $800/yr minimum franchise tax, Massachusetts $500/yr annual report, North Carolina $200/yr annual report, New York biennial statement + publication, Illinois $75/yr + LLC replacement tax — a Missouri LLC held for 10 years pays $50 total in state-level maintenance vs a California LLC at $8,070. What DOES change periodically and must be kept current: if your registered agent resigns, moves, or changes entity type, you must file a Statement of Change of Registered Agent ($10). If your principal office address changes, file a Statement of Change of Principal Office or Mailing Address ($10). Articles of Amendment for other changes (name, management structure) cost $20. But in steady-state — no changes, same registered agent, same principal office — you file nothing and pay nothing to the Missouri Secretary of State ever again after formation. On a lifetime basis, a Missouri LLC is among the cheapest US entities to maintain.

Both St. Louis City and Kansas City levy a 1% earnings tax — a locally administered income tax on wages and self-employment net earnings sourced to the city. The tax applies to (a) city RESIDENTS on all earnings regardless of where earned, and (b) NON-RESIDENTS on earnings from work performed within the city limits. Both cities administer the tax separately through their own Earnings Tax Divisions, not the Missouri Department of Revenue. Voters must renew the earnings tax every 5 years under Missouri state law — St. Louis last renewed in 2021 (next vote 2026), and Kansas City last renewed in 2021 (next vote 2026). Both renewals have passed every cycle since the tax was enacted. Functionally, this means: (1) If your LLC has employees working in St. Louis City or Kansas City, you must register for Employer Earnings Tax withholding with the respective city, withhold 1% from their wages, and remit quarterly. St. Louis filings go to collectorstlouis.com / stlouis-mo.gov; Kansas City filings go to kcmo.gov/revenue. (2) If you are a single-member LLC with self-employment earnings sourced to work performed in St. Louis or Kansas City, you personally owe 1% on that earned income (reported on Form E-1 St. Louis or Form RD-109 Kansas City). (3) Multi-member LLCs report partnership-level earnings tax on Form E-234 (St. Louis) or Form RD-112 (Kansas City). (4) Corporations (including LLCs electing C-Corp) pay corporation earnings tax on city-sourced net earnings — 1% St. Louis on Form E-234, 1% Kansas City on Form RD-110. This is the single most commonly missed Missouri tax for out-of-state founders — national formation services almost never mention it. If your LLC activity is entirely outside St. Louis City limits and Kansas City city limits, you owe no earnings tax (including suburbs like Clayton, Maryland Heights, Chesterfield, Creve Coeur, Kirkwood, Webster Groves, Des Peres, Town and Country — all of which are in St. Louis COUNTY but outside St. Louis CITY and therefore exempt from the City earnings tax). Similarly for Kansas City: suburbs like Independence, Lee's Summit, Blue Springs, Raytown, and Gladstone sit within the KC metro but outside KCMO city limits and do not owe the 1% KC earnings tax.

Every Missouri LLC must designate a registered agent (RSMo § 347.030) with a physical Missouri street address — no P.O. boxes, no mail-drop addresses, no CMRA addresses. The registered agent receives service of process and official government correspondence on behalf of the LLC during normal business hours. Missouri uses the standard "registered agent" terminology, unlike Arizona/Ohio (which call this role a "statutory agent") or Maryland/Michigan/Massachusetts (which call it a "resident agent"). Eligibility is permissive: (a) a Missouri-resident individual 18 or older, OR (b) a domestic or foreign business entity authorized to transact business in Missouri and consenting to serve. You can serve as your own agent if you are a Missouri resident and accept service during business hours — but your home address becomes public on the Articles of Organization and the Missouri Secretary of State business entity search. Most founders use a commercial registered agent for three reasons: (1) privacy — your home address would otherwise appear on the public Articles filed with the Missouri Secretary of State and searchable on the Business Services portal at sos.mo.gov/business; (2) uptime — you cannot legally miss service of process because you were out of town, at a conference, in the hospital, or simply having a bad day (missed service can lead to default judgments); (3) out-of-state founders — commercial registered agents are the only practical option if you don't have a Missouri address, and Missouri welcomes non-resident LLC formations. Eleet AI's Missouri registered agent service is included free in year one with formation, then $100/yr after. Our Missouri agent address is a commercial location with live coverage during business hours, and we scan every piece of service or state correspondence and notify you within one business day.

Missouri online filings through sos.mo.gov/business are typically processed same-day to 5 business days from submission. The Secretary of State's Business Services Division processes Articles of Organization in the order received, with most online filings completed within 1–3 business days under normal volume. Missouri does not offer a paid expedited processing tier for LLC formation — the state's position is that online processing is already fast enough that paid expedite isn't needed. Paper filings (Form LLC-1 mailed to the Secretary of State office in Jefferson City) add 1–2 weeks on top of processing. For comparison: Arizona standard is 14–20 business days with $35 gold expedite and $100 same-day tiers; Delaware is 10+ business days standard with $50–$1,000 expedite tiers; California is 5–10 business days standard with $350 same-day; Ohio is 3–7 business days standard with $300 for 4-hour expedite; Colorado is same-day with no expedite needed. Missouri sits firmly in the "modern fast-processing states" category — filings usually approve same-day to end-of-week. Eleet AI includes online filing in our $199 base — no upsell for expedite because it's not available and not needed. Typical timeline from checkout to live Missouri LLC with Articles approved: 24–72 hours during business-week. After approval, you'll want to get an EIN (5 minutes at IRS.gov), open a business bank account (same-day with the approved Articles + EIN), and register for any Missouri tax accounts your activity triggers (mytax.mo.gov).

Missouri is a moderate-tax Midwest state with several genuine honesty points national formation articles universally skip. Key taxes: (1) State individual income tax — graduated 0% to 4.7% as of 2025, applied to LLC member distributive shares for pass-through LLCs. Missouri has been reducing its top rate under SB 509 (2014) and HB 2816 (2022) revenue-trigger legislation — the top rate stepped down from 5.4% (2018) to 5.3% (2019) to 5.2% (2020) to 5.4% (2021) to 4.95% (2023) to 4.8% (2024) to 4.7% (2025) — with further reductions to 4.5% contingent on revenue triggers in future years. On $100k of LLC pass-through income, Missouri state tax is roughly $4,300/yr after the standard deduction — lower than Illinois ($4,950 flat 4.95%), higher than Ohio (top 3.99% = $3,990), similar to Colorado (4.4% flat = $4,400). (2) State corporate income tax — 4.0% flat rate as of 2024 (reduced from 6.25% in 2020 under SB 884), applied only if the LLC elects C-Corp taxation. (3) Corporate franchise tax — PERMANENTLY ELIMINATED effective Jan 1, 2016 under HB 184 (2015). Zero for all entities. (4) State sales tax — 4.225% state rate (RSMo § 144.020) — lowest Midwest general sales tax. Local add-ons (county + city + fire protection + transportation district + tourism tax) stack on top, pushing combined rates to ~8.25% statewide average, ~9.9% in St. Louis County, ~9.975% in Kansas City. Register via mytax.mo.gov. (5) St. Louis City earnings tax — 1% on residents and on non-residents working in St. Louis City limits (voter-renewed 2021, next vote 2026). (6) Kansas City earnings tax — 1% on residents and on non-residents working in Kansas City limits (voter-renewed 2021, next vote 2026). (7) Use tax — 4.225% plus local for out-of-state purchases brought into Missouri. (8) Missouri Pass-Through Entity (PTE) tax — elective under HB 1320 (2022) / SB 671 (2022) codified at RSMo § 143.436, lets partnership-taxed and S-Corp-taxed LLCs pay state income tax at the entity level (federal SALT cap workaround) with corresponding owner credit. Worth evaluating for higher-income LLCs. (9) Self-employment tax (15.3% federal) is separate and applies regardless of state. (10) Missouri has no state-level general business license (most industries) — saves founders from a bogus LegalZoom upsell. Industry-specific professional licensing exists through Missouri Division of Professional Registration, Missouri Division of Insurance, Missouri Division of Alcohol and Tobacco Control, Missouri Gaming Commission (St. Louis/Kansas City casino corridor), Missouri Public Service Commission, and others. LLCs with employees register with Missouri Department of Revenue (income tax withholding via mytax.mo.gov), Missouri Division of Employment Security (unemployment insurance via uinteract.labor.mo.gov), and a workers' compensation carrier (Missouri Employers Mutual is the state-affiliated option; private carriers are also permitted).

Often yes if your business has genuine Missouri economic substance, and MO is also competitive for out-of-state founders who value the zero-annual-fee + member-privacy combo. Legitimate Missouri advantages: (1) Aerospace and defense cluster — Boeing Defense, Space & Security has its global headquarters in St. Louis (Hazelwood/Berkeley campus) producing F-15EX Eagle II, F/A-18 Super Hornet, EA-18G Growler, T-7A Red Hawk Air Force trainer, MQ-25 Stingray Navy carrier drone, and running Phantom Works advanced prototyping. Whiteman Air Force Base in Johnson County is the only US B-2 Spirit stealth bomber base (509th Bomb Wing) and will host the B-21 Raider as it comes online. Fort Leonard Wood in Pulaski County is the US Army Engineer School, Chemical Corps School, and Military Police School. If you are building in aerospace, defense electronics, ISR, tactical communications, munitions, or military training services, Missouri has real industrial substance. (2) Fortune 500 density in St. Louis — Boeing Defense, Emerson Electric (Ferguson), Anheuser-Busch InBev North American HQ, Bayer Crop Science (Creve Coeur, inherited Monsanto), Edward Jones (Des Peres), Centene (Clayton), Reinsurance Group of America (Chesterfield), Post Holdings, Peabody Energy, Ameren, Enterprise Holdings (Clayton), Graybar Electric, World Wide Technology (Maryland Heights), Stifel Financial, Express Scripts (now Evernorth/Cigna). St. Louis metro has one of the highest F500 densities per capita in the Midwest. (3) Kansas City Fortune 500s — H&R Block HQ (international tax preparation), Hallmark Cards HQ, Oracle Health (formerly Cerner, North Kansas City — acquired by Oracle in 2022 for $28.3B, largest healthcare IT company in the US), Commerce Bancshares HQ, Burns & McDonnell engineering, American Century Investments, Dairy Farmers of America HQ. (4) Springfield F500 — Bass Pro Shops HQ (largest outdoor retailer in North America) and O'Reilly Automotive HQ (top-3 US auto parts retailer) — rare for a sub-500k metro. (5) Two Federal Reserve Banks — Missouri is the ONLY US state with two regional Federal Reserve Banks (Federal Reserve Bank of St. Louis, 8th District; Federal Reserve Bank of Kansas City, 10th District). Unique financial-services infrastructure for fintech, bank-adjacent, treasury-services, or economic-research LLCs. (6) Cortex Innovation District St. Louis — 200-acre urban innovation district in Central West End anchoring 150+ startups, BioGenerator incubator, Washington University biomedical spinouts, Donald Danforth Plant Science Center. Premier Midwest innovation cluster. (7) Zero annual report fee + no franchise tax = lifetime-cheapest LLC state maintenance. (8) Member privacy — Articles of Organization do NOT require individual member names (closer to Delaware than to Arizona). But weigh these against: (a) St. Louis and Kansas City 1% earnings taxes if you or your employees work in those city limits; (b) moderate state income tax (4.7% top, reducing) — zero-income-tax states (TX, FL, NV, WY, WA, TN, SD, NH, AK) are meaningfully cheaper for high-income founders; (c) no series LLC — if you need series separation for real estate portfolios or multi-line businesses, form in DE/IL/TX/LA and foreign-qualify in Missouri; (d) VC-backed startups planning institutional funding rounds typically form in Delaware for cap table flexibility and register Missouri as a foreign LLC/Corp to operate. For the typical Missouri-based founder — bootstrapped service business, professional practice, real estate holding, small-batch manufacturing, aerospace/defense supplier, or F500-adjacent consulting — forming natively in Missouri is the right call. The $0/yr state compliance cost + member privacy on Articles + elimination of franchise tax + modern online SOS portal combine to a genuinely founder-friendly formation regime.

Missouri does not legally require an LLC operating agreement (RSMo § 347.081 permits but does not mandate one), but you should have one anyway. Without it, your LLC is governed entirely by the Missouri Limited Liability Company Act (RSMo Chapter 347, enacted 1993 and updated repeatedly) — a modern statute with sensible default rules that rarely match how partners actually want profits distributed, decisions made, capital contributed, or ownership transferred. For single-member LLCs, the operating agreement strengthens the liability shield by demonstrating that the LLC is a separate business entity rather than a personal extension (RSMo § 347.119 codifies charging-order protection as the exclusive creditor remedy, so Missouri's single-member-LLC shield is comparatively strong, but documentary separation still matters in court). For multi-member LLCs — particularly common in St. Louis real estate partnerships, Kansas City professional-services firms, Springfield outdoor-industry JVs, aerospace/defense supplier combinations around Boeing and Whiteman AFB, and Bayer Crop Science-adjacent agtech spinouts — the operating agreement is where the actual deal lives: capital contributions, profit splits, voting thresholds (often weighted by capital), transfer restrictions, buy-sell provisions, drag-along and tag-along rights, preemptive rights on future raises, employee profits-interest grants, and dissolution triggers. Missouri codifies charging-order exclusivity at RSMo § 347.119, meaning a creditor of a member cannot directly seize the member's LLC interest — only a charging order against distributions is available, protecting the remaining members from business disruption. Eleet AI offers a Missouri-specific operating agreement template for $99; for complex multi-member deals with outside investors or anticipated Delaware flip-up, talk to a Missouri business attorney (Bryan Cave Leighton Paisner, Thompson Coburn, Armstrong Teasdale, Husch Blackwell, Polsinelli, and Stinson LLP are all active in Missouri business law with offices in St. Louis and Kansas City).

Yes. Missouri welcomes non-resident LLC formations, and the Secretary of State's Business Services Division processes filings from all 50 states and international founders through sos.mo.gov/business. The only Missouri-resident requirement is the registered agent (commercial agents like Eleet AI satisfy this). However, consider the foreign-qualification trap: if you actually operate your business mainly in another state (employees there, storefront there, services delivered from there), that state will likely require you to register your Missouri LLC as a "foreign LLC" in the operating state, adding another filing fee, another registered agent, and another annual report. Missouri's strongest non-resident use cases are: (1) low-compliance holding company — zero annual report + zero franchise tax + member privacy on Articles makes MO competitive for pass-through holding LLCs that own real estate, intellectual property, or investment portfolios; (2) aerospace/defense/agtech supply-chain business — Missouri has genuine industrial substance for Boeing-adjacent, Whiteman-adjacent, Fort Leonard Wood-adjacent, and Bayer Crop Science-adjacent businesses; (3) Missouri relocation plan — if you intend to move to St. Louis, Kansas City, Springfield, Columbia, or the Ozarks within 1–2 years, forming MO now makes operational sense; (4) Federal Reserve-adjacent financial services — unique two-Fed infrastructure supports fintech, economic-research, bank-adjacent LLCs. If you just want the cheapest LLC to register-and-hold with no intended Missouri operations AND you specifically want maximum anonymity, Wyoming ($60/yr anonymous, W.S. § 17-29-201 member privacy) or New Mexico ($50 filing + no annual + anonymous) have a meaningful edge: both states publish zero member information publicly, whereas Missouri publishes the management structure designation (member-managed vs manager-managed) and the organizer's name. Missouri's privacy is strong but not anonymous-LLC-grade.

Missouri is the ONLY US state with two regional Federal Reserve Banks — a genuinely unique piece of national financial-services infrastructure. The Federal Reserve System has 12 regional districts; Missouri houses the Federal Reserve Bank of St. Louis (8th District) and the Federal Reserve Bank of Kansas City (10th District). This dates back to the 1914 formation of the Fed: when the Reserve Bank Organization Committee chose the 12 cities, St. Louis and Kansas City were both selected due to their economic importance in their respective regions (St. Louis for the Ohio Valley / mid-South corridor; Kansas City for the Great Plains / Western ranching corridor). This historical accident has compounded into significant modern financial infrastructure: (1) Federal Reserve Bank of St. Louis runs FRED (Federal Reserve Economic Data) — the most-used economic database in the world, widely cited in academic research, policy analysis, and financial news; FRASER (historical economic documents); and hosts the Research Division publishing Review journal; (2) Federal Reserve Bank of Kansas City hosts the annual Jackson Hole Economic Symposium — the most important central-banker gathering of the year, where Fed Chairs traditionally signal major monetary policy shifts; also maintains the 10th District Survey of Business Expectations and regional economic research; (3) Both Reserve Banks provide payment services, currency distribution, bank supervision, and monetary policy research to hundreds of member banks; (4) The concentration of Federal Reserve infrastructure in Missouri creates genuine career and business-opportunity density for fintech founders, economic researchers, bank examiners, payment-processing startups, and monetary-policy-adjacent consultants. For an LLC in the fintech, banking-software, payment-processing, or economic-research space, Missouri's dual-Fed status is a legitimate industrial-substance advantage over nearly every other state (only Virginia + DC, New York, California, and Massachusetts have comparable central-banking density). Practical implication: if you're building a bank-adjacent or Fed-adjacent LLC, Missouri is a substantively stronger home state than most people realize.
