Introduction
Starting a Missouri LLC raises a lot of practical questions — about costs, timelines, registered agents, and what the state actually requires. This FAQ covers the most common ones so you know what to expect before you file.
What you need to know about forming a Missouri LLC
Forming an LLC in Missouri involves a handful of steps — choosing a business name, appointing a registered agent, filing Articles of Organization with the Missouri Secretary of State, and getting your federal Employer Identification Number (EIN). The questions below cover each of those steps, along with the costs, timelines, and requirements that come up most often. If your question isn't here, the Missouri Secretary of State's office and the IRS are the authoritative sources for state filing and federal tax requirements.
Missouri LLC frequently asked questions
It depends on how you file. Online filings with the Missouri Secretary of State are typically processed faster than paper submissions. Paper filings sent by mail can take 4 to 6 weeks. If you need your LLC sooner, filing online is the faster path.
Processing times can shift during busy periods, so check the Missouri Secretary of State's website for current estimates before you file.
The Missouri Secretary of State charges $105 to file Articles of Organization by paper and $50 to file online. The online fee is lower and the processing time is faster, so most people file online. These are state fees paid directly to Missouri — they're separate from any service fees.
To form an LLC in Missouri, you need 3 things: a business name that's available in the state, a registered agent with a Missouri street address, and completed Articles of Organization filed with the Missouri Secretary of State along with the state filing fee.
Before you file, it's worth checking name availability through the Missouri Secretary of State's business search tool and drafting an operating agreement — Missouri doesn't require one, but it protects how your LLC is run.
Yes. Missouri allows you to serve as your own registered agent as long as you have a physical street address in Missouri and are available during normal business hours to receive legal documents. A P.O. box doesn't qualify.
Many business owners use a registered agent service instead. It keeps your personal address off public records and means you won't miss a legal notice if you're traveling or away from the office.
A Series LLC is a special LLC structure that allows one parent LLC to hold multiple separate series — each with its own assets, members, and liability protection. Missouri law permits Series LLCs. Each series can operate independently, and the debts of one series generally can't reach the assets of another.
Series LLCs are most common in real estate, where investors hold multiple properties under one umbrella. The structure is more complex than a standard LLC, so talking to a legal professional before forming one is worth the time.
It depends on your situation. Missouri businesses can be formed as LLCs, S Corporations, or C Corporations. For most entrepreneurs starting out, an LLC offers a practical mix of personal liability protection and straightforward administration — without the formality requirements of a corporation.
S Corps and C Corps make more sense in specific situations — for example, if you're raising outside investment or planning to issue stock. A tax professional can help you figure out which structure fits your goals.
It depends on your LLC's structure. Multi-member LLCs, LLCs with employees, and LLCs that elect corporate tax status are required to get an Employer Identification Number (EIN) from the IRS. Single-member LLCs without employees may use the owner's Social Security number for federal tax purposes instead.
Getting an EIN is free and takes minutes through the IRS online application, available Monday through Friday, 7 AM to 10 PM ET. You'll also need to register with the Missouri Department of Revenue if your LLC has employees or sales tax obligations.
Generally, no. Missouri's corporate franchise tax does not apply to standard LLCs. It applies only if your LLC has elected to be taxed as a C Corporation. If your LLC is taxed as a sole proprietorship, partnership, or S Corporation, you won't owe Missouri franchise tax.
Yes, most Missouri businesses need at least one license or permit to operate. Missouri doesn't issue a single statewide business license — requirements vary by industry, business type, and the city or county where you operate. Some professions require state-level licensing; others require local permits.
Check with your city or county clerk's office and the Missouri Division of Professional Registration to figure out what applies to your business.
You can search existing business names through the Missouri Secretary of State's online business search tool. Your LLC name needs to be distinguishable from other registered businesses in Missouri and must include "Limited Liability Company," "LLC," or "L.L.C." in the name.
If you find the name you want is available but you're not ready to file yet, Missouri allows you to reserve a business name for a period of time for a small fee.
A few mistakes come up often. Not checking name availability before filing can mean starting over. Skipping an operating agreement leaves your LLC governed by Missouri's default rules, which may not match how you want to run things. Not getting an EIN when you need one can create problems with banking and taxes.
Missing your registered agent requirement is another one — if you don't have a registered agent with a Missouri address on file, the state can't reach you with legal notices, and your LLC can fall out of good standing.
