Forming a series LLC in Missouri in 2026. Missouri authorises series LLCs under Mo. Rev. Stat. §347.186 (Missouri LLC Act). This guide covers the statutory framework, formation cost, how series are created, Missouri-specific tax and banking notes, and where Missouri series LLCs fit relative to Delaware and Texas — the two largest series jurisdictions.
Missouri's series LLC framework is codified at Mo. Rev. Stat. §347.186 (Missouri LLC Act). Missouri's combination of low filing fees and no annual report makes it one of the cheapest series-LLC jurisdictions, especially for small real-estate portfolios held by Missouri residents.
A Missouri series LLC consists of a master LLC plus one or more series. Each series can hold its own assets, take on its own debts, and contract in its own name. Series are typically created internally in the operating agreement; some states require an additional public filing per series. Each series should maintain separate books and records to preserve the inter-series liability shield.
Cost: $50 Articles of Organization filing fee — among the cheapest in the US. No annual report. Per-series creation is internal.. Timeline: Missouri processes filings in 1-5 business days. End-to-end Anonymousllc.co series LLC formation in Missouri averages 5-10 business days including operating agreement drafting, EIN, and partner bank applications. Anonymousllc.co flat formation rate $397 + state fees as listed.
For federal tax, IRS Proposed Reg §301.7701-1(a)(5) (2010) treats each series as a separate entity. Most Missouri series LLCs file separate tax returns per series (typically Form 1065 partnership returns or Schedule C disregarded-entity treatment). For state tax, Missouri generally follows federal treatment but check Anonymousllc.co's /series-llc/tax-treatment/ guide for the up-to-date position.
Banking is the practical pain point for series LLCs. Mercury, Relay, and Bluevine open accounts for Missouri series LLCs with extra documentation (Certificate of Designation or equivalent + operating agreement language showing the series). Anonymousllc.co submits applications to 4-5 partner banks in parallel; series LLC approval averages 10-14 days.
Before forming a Missouri series LLC, consider whether two or three standalone LLCs would serve you better. Series LLCs win on filing-cost economics when you operate four or more separate entities and on liability segregation when you hold distinct assets (real estate, IP). They lose on bank acceptance, multi-state operations (states without series statutes may not recognise the inter-series liability shield), and tax-prep simplicity. Anonymousllc.co's intake will steer you to the simpler structure when it fits.
