Missouri LLC Formation Cost: What You'll Actually Pay to Form an LLC

The cost of forming an LLC in Missouri is one of the first questions founders ask — and the honest answer is that it depends on what you include. The state filing fee is set by the Missouri Secretary of State, but the total cost also covers your registered agent, EIN application, and any license or tax-registration steps. Here's a clear breakdown of what you'll actually pay, and how to keep the total reasonable.

The state filing fee

The core cost is the Missouri Secretary of State's filing fee for Articles of Organization. It's a flat fee regardless of your LLC's size or revenue. We tell you the exact current state fee in our quote — see our Missouri LLC formation page for the full package.

Registered agent service

Every Missouri LLC needs a registered agent, and that service carries an annual fee. The cost varies by provider, but a local agent who actually forwards your mail promptly is worth more than a cheap national mailbox that doesn't. We offer Missouri registered agent service at a flat annual rate that includes receipt, scanning, and forwarding.

EIN application (free from the IRS, help optional)

Applying for an EIN through the IRS is free — but many founders prefer to have it handled as part of a formation package so it's done right the first time. We include EIN application help in our formation package or offer it on its own.

Business license and tax registration

Depending on your business activity and location, you may need a city or county business license and Missouri sales tax registration. Each carries its own fee set by the city, county, or state. We give you a clear checklist so you know which apply to you — see our EIN and business license help page.

Optional: a business address and virtual office

If you'd rather not use your home address on filings, a virtual office and business address gives you a real St. Louis street address for banking, licensing, and your registered agent. It's a modest monthly cost that pays off in privacy and professionalism.
