Best LLC Services in Missouri (2026)

ZenBusiness is the highest-rated LLC formation service on Trustpilot and the choice we'd recommend to most first-time founders. Their free Starter plan covers all the basics — state filing, registered agent for year one, and a compliance dashboard that tracks your annual report deadlines. Worry-Free Compliance ($199/yr after year one) is genuinely useful if you'd rather not track state deadlines yourself; skip it if you will. Their checkout flow is notably cleaner than competitors with fewer pre-checked upsells at critical decision points. In our support testing, chat response times were consistent and issues reached resolution without escalation.

Bizee (formerly Incfile) is the right choice if minimizing registered agent renewal cost is your priority. At $119/yr for RA renewal, they're the cheapest major service once year-one promotions expire — $80/yr less than ZenBusiness, $130/yr less than LegalZoom. Their Gold plan uniquely bundles IRS Form 2553 (S-Corp election filing), EIN application, and a banking resolution document — features no other starter plan includes at this price. The F BBB rating reflects a documented pattern of unresolved customer complaints, most commonly around unexpected renewal charges and difficulty canceling add-ons. We include Bizee because the pricing is genuinely competitive, but read every auto-renewal term before completing checkout.

LegalZoom is the oldest and most recognized name in the space, having helped form more than 4 million business entities since 2001. For a simple single-member LLC, they're overkill at $249/yr in registered agent fees — the highest of any service we reviewed, and not included in any plan. But if your situation involves multiple members with non-equal ownership, IP or trademark concerns, or an operating agreement with unusual terms, their Premium plan's attorney access changes the math: unlimited 30-minute consultations during your first 30 days with a licensed attorney is a service no other formation company offers. Budget the full first-year cost — RA adds $249 on top of the plan price before you start.

Northwest Registered Agent is the best choice for founders who want a no-frills formation with no upsells, no spam, and no data sharing. Based in Montana, they own their own server infrastructure specifically to maintain control over customer data — a meaningful differentiator in a market where competitors routinely monetize contact lists with third-party vendors. The $39 formation fee is higher than the $0 starter plans at ZenBusiness and Bizee, but registered agent is included in year one making the true first-year cost competitive. Northwest is not for founders who want an EIN filed for them, a compliance dashboard, or step-by-step hand-holding. It's for founders who want the filing done cleanly, a $125/yr registered agent with no surprises, and nothing else.

Missouri note: Missouri allows anonymous LLC ownership, and Northwest Registered Agent's privacy-first setup (address shielding, no owner data resale) pairs well with it.
