Cheapest LLC Formation Services in Missouri (2026)

If you want a single recommendation, ZenBusiness is the service we point most Missouri founders to first. It pairs a genuinely $0 formation filing with a clean compliance dashboard and registered agent service, so the one thing Missouri actually requires long-term is handled from inside one account. That blend of a free entry point and built-in compliance tracking is what earns it the top spot here.

State filing fees are paid to the Missouri Secretary of State and are separate from any service fee. Online filing is the cheaper and faster route.

ZenBusiness files your Missouri LLC for $0 in service fees and wraps the formation, registered agent option, and compliance monitoring into one modern dashboard.

Key features: $0 Starter formation (you pay only the $50 state fee); a polished dashboard and mobile app that show exactly where your filing stands; Worry-Free Compliance that flags state deadlines and is free the first year; registered agent service available as an add-on; and optional EIN and operating agreement on higher tiers.

Best for: Missouri owners who want the lowest possible entry cost and a service that quietly keeps them in good standing without much effort.

Pricing tier: Free formation. Pro runs about $199 a year and adds an EIN and operating agreement; Premium runs roughly $349 a year as of 2026 and folds in registered agent service. Registered agent on its own is $199 a year, and Worry-Free Compliance renews at $199 a year after the first year.

Pros: A truly free formation filing; the cleanest interface in the category; genuinely useful deadline tracking, which matters because Missouri's main compliance trap is letting your registered agent lapse rather than missing a report; responsive support and a strong Trustpilot record across tens of thousands of reviews. In a no-annual-report state, the combination of $0 filing and automated compliance reminders covers almost everything a typical owner needs.

Cons: The "$0" headline applies to the filing only—budget for the registered agent if you use ZenBusiness for it, and watch the Worry-Free Compliance auto-renewal so it doesn't surprise you in year two.

Northwest charges $39 plus the state fee and includes a full year of registered agent service, then renews that service at $125 a year—the lowest among the major brands.

Key features: $39 formation with a free first year of registered agent service; a privacy stance that keeps your address off public records and explicitly does not sell customer data; mail scanning and same-day document uploads; annual report and deadline reminders; and U.S.-based support staffed by people who actually know formation.

Best for: Owners whose top priorities are to address privacy and the cheapest registered agent renewal over many years.

Pricing tier: $39 + state fee up front; $125 a year for registered agent after the first year.

Pros: The strongest privacy posture in the group, a flat and transparent price with no tier games, and a registered agent renewal that beats ZenBusiness, LegalZoom, and Bizee on cost. Over several years the math is genuinely competitive.

Cons: The dashboard feels dated next to ZenBusiness, there's no live chat, and you pay a small fee up front rather than nothing. For a first-time owner who values an intuitive interface and built-in compliance prompts, ZenBusiness is the smoother experience, even though Northwest's agent renewal is cheaper.

Bizee (formerly Incfile) offers $0 formation plus the state fee and a free first year of registered agent service, making it a low-friction way to get an entity on file.

Key features: free basic formation; a simple step-by-step formation wizard; a free first year of registered agent service; lifetime compliance alerts; and a long track record of more than a million businesses formed under the Incfile and Bizee names.

Best for: Cost-sensitive owners who just want the filing done and are comfortable managing the rest themselves.

Pricing tier: $0 + state fee. Registered agent renews in the range of roughly $120 to $200 a year as of 2026, depending on the promotion in effect.

Pros: A free entry point, an easy interface, and useful ongoing alerts at no charge.

Cons: Standard processing can run several weeks, the registered agent renewal costs more than Northwest's, and the platform offers fewer guided compliance tools than ZenBusiness. It's a solid budget option but thinner on the hand-holding most new Missouri owners appreciate.

LegalZoom is the most recognized name in online legal services and now offers $0 formation plus the state fee, with deeper legal offerings layered on top.

Key features: free basic formation; access to attorneys on higher tiers; trademark, will, and contract services beyond formation; registered agent service; and compliance add-ons.

Best for: Owners who want a household-name provider or expect to need attorney access and broader legal services down the road.

Pricing tier: $0 + state fee for basic formation; Pro and Premium tiers run roughly $249 to $299 as of 2026. Registered agent service is $249 a year—the highest among these brands.

Pros: Deep legal capabilities, optional attorney consultations, and the reassurance of a well-known brand with millions of customers served.

Cons: The priciest registered agent renewal in this list and a checkout known for pushing add-ons. For a straightforward Missouri LLC focused on minimal compliance, you're paying a premium for the name and for legal features many small owners never use—ZenBusiness delivers the core job for less.

Rocket Lawyer approaches formation through a legal-subscription lens, which suits owners who want document templates and attorney access alongside the filing.

Key features: LLC formation around $100 plus the state fee (often discounted or free for members); a membership that unlocks legal documents and attorney Q&A; registered agent service; and ongoing access to contracts and legal forms.

Best for: Owners who anticipate recurring legal needs and want them under one subscription.

Pricing tier: Roughly $100 + state fee to form (free or discounted on a paid membership); registered agent runs about $150 a year. The value depends heavily on whether you keep the monthly membership.

Pros: Strong library of legal documents, genuine attorney access, and an established platform used by millions.

Cons: The economics only work if you actually use the membership; for formation alone, it's more expensive and more complex than ZenBusiness or Bizee. A Missouri owner who simply wants to form and stay compliant doesn't need the subscription overhead.

Tailor Brands offers $0 formation plus the state fee and pairs it with logo and branding tools, which is its real differentiator.

Key features: free basic formation; logo maker and branding kit; website and business-identity tools; an annual compliance package; and a registered agent option.

Best for: Founders launching a customer-facing brand who want a logo, website, and entity from one provider.

Pricing tier: $0 + state fee for formation. The compliance package runs $199 a year, and registered agent service is currently available only when added to a formation order.

Pros: A handy all-in-one for brand-first launches, with design tools the other services don't offer.

Cons: Customer reviews are more mixed than the leaders here, the registered agent restriction is limiting if you ever want to switch, and the branding focus is beside the point if you only need a compliant entity. For pure low-cost formation and compliance, ZenBusiness is the cleaner fit.

Because Missouri imposes no LLC annual report and no franchise tax, your real ongoing task is keeping a registered agent on file and tracking the occasional local license or tax item—so the best "cheapest" service is the one that makes that effortless. ZenBusiness wins that test for most owners by combining a truly free formation filing, a registered agent option, and the strongest compliance dashboard in the category, all in an interface a first-timer can navigate without help. If your single highest priority is the lowest registered agent renewal year after year or maximum address privacy, Northwest Registered Agent is the smart alternative and a close runner-up; Bizee works if you want the barest free filing, while LegalZoom, Rocket Lawyer, and Tailor Brands make sense mainly when you need their legal or branding extras. For a Missouri LLC built to be cheap to start and nearly hands-off to maintain, start with ZenBusiness.
