$200 in December, $100 in January: What a St. Louis Business Really Costs to Start
Revised October 21, 2026
How much money does it cost to open a small business in St. Louis?
Less than the checkout pages suggest. A Missouri LLC costs $50 to file online and never needs an annual report, while an Illinois LLC costs $150 plus a $75 annual report every year. The IRS issues an EIN for free. Inside City of St. Louis limits, the business license starts at $200, or $100 if you start after January 1. Insurance and winning customers cost more than the paperwork.
Keep reading ↓Two people carry the same folder into Room 104 of St. Louis City Hall, a week apart. Same one-person crew, same paperwork going soft at the corners from riding around on the passenger seat all week, same damp thumb on the edge of it while the line inches toward the counter. The one who walks in the last week of December pays $200.00 for a Graduated Business License. The one who walks in the first week of January pays $100.00. Both licenses expire on the same day, May 31. Nobody at the counter warned the first one.
That isn’t a loophole. It’s printed on the City’s own fee schedule: new businesses that start between June 1 and January 1 pay $200.00, and new businesses that start after January 1 and up to May 31 pay $100.00. No checkout page and no formation site puts that date in front of you. If your launch date can slide a few days, that’s a hundred dollars the process was never going to mention.
Most of us meet this process the same way: at the kitchen table at 11 p.m., still in the work shirt from a shift that ran long, the laptop fan whirring, a formation website’s checkout page glowing in the dark kitchen. A registered agent subscription. An “EIN package.” Rush processing. Each add-on worded like the State would turn you away without it. The page was built to sell add-ons, not to tell you about January.
Here’s what the State actually charges. The Missouri Secretary of State takes $50.00 to file an LLC’s articles of organization online, or $105.00 on paper, and its own FAQ asks, “Do limited liability companies have to file an annual report?” The answer is one word. No. And that EIN package? The IRS says it on its own application page, in a sentence worth taping to the fridge: “You never have to pay a fee for an EIN.”

Less than the checkout pages suggest. A Missouri LLC costs $50 to file online and never needs an annual report, while an Illinois LLC costs $150 plus a $75 annual report every year.

Insurance and winning customers cost more than the paperwork.
The City adds two details the formation sites never mention. First, you must obtain a Graduated Business License before commencing business activity, and the City’s license page says, word for word, that registering for an LLC does not qualify as a business license in the City of St. Louis. The $50 receipt from Jefferson City doesn’t open the door at 1200 Market Street.
Second, renewals are priced by the number of St. Louis employees, and the fee schedule counts “owners, partners and officers” in that number. In the City’s eyes, you are an employee of your own business. At 0-2 employees the renewal is $200 a year, and it has to be paid before June 1 to avoid penalties. Write June 1 on the calendar the day the license arrives.
Where do you actually go? The Office of the License Collector is at 1200 Market Street, City Hall Room 102-104, and answers at (314) 622-4528, Monday through Friday, 8 a.m. to 5 p.m. Call before you go, because fee schedules get updated. The LLC itself is filed online with the Secretary of State, and online fees are paid by credit card.
Across the river, the bill comes back every year
Drive east over the Mississippi, the bridge joints thumping under the tires, and the math changes. Under the Illinois Limited Liability Company Act, filing articles of organization costs $150. Then the annual report costs $75, every year the company exists. Miss it and the statute adds a penalty of $100, plus another $100 for each further year the company stays delinquent.
The timing is fussy, too. The Illinois act says the report is due within the 60 days before the first day of the company’s anniversary month. Put that month on the calendar the day you file, right next to the lease renewal.
Neither number will sink a business. But one state sends you a bill every year and the other never does, and that difference compounds quietly while you’re busy doing the work. If you live on one side and work on the other, ask an accountant once where your business really operates. Where you do the work drives what you owe, not where the filing is cheaper.
What you do not have to buy
Most of what people spend forming a business is optional. The add-ons sell hard because the margins are good, and the checkout pages are built for the hour when anyone would be tired and nervous at the kitchen table.
A formation service. Filing directly with the Secretary of State is the same filing. A service is a convenience purchase, not a legal requirement.
A paid registered agent, maybe. Missouri’s FAQ says an agent may be an individual who is a resident of Missouri and whose business office is identical with the entity’s registered office. For a lot of one-person shops, that’s you. The honest reason to pay someone is privacy, because the agent’s address goes on the public record.
A “business license package.” The Secretary of State’s own FAQ explains that a business license comes from your city or county and is not the same as the certificate of organization it issues. Our guide to what licensing you actually need in St. Louis covers which office to visit.
A trademark on day one. Worth doing later if the brand takes off. Not a startup cost.

The $7 filing almost nobody mentions
If you answer the phone with any name that isn’t your own legal name or your LLC’s exact registered name, Missouri wants a fictitious name registration, the thing everyone calls a DBA. The cost for registering a fictitious name is $7, and the registration is good for five years. It catches sole proprietors most often, because nothing in the process flags it: no formation filing, no reminder, no form that mentions it. The name on the side of the truck still counts.
The state filing, side by side
| Cost | Missouri | Illinois |
|---|---|---|
| Form an LLC (online) | $50 | $150 |
| Form an LLC (paper) | $105 | $150 |
| Annual report | None required | $75 per year |
| Federal EIN | Free | Free |
Total tangent - but North Riverfront rewards an afternoon of curiosity.
The costs that show up in month two
Formation is cheap. These are the bills that arrive after the excitement wears off.
Insurance. General liability is the real first bill for most service businesses, and premiums swing hard by trade. A bookkeeper and a roofer live in different worlds, which is worth weighing while you decide which services to build the business around. Get two or three real quotes.
A separate bank account. Once you have an LLC, mixing personal and business money can quietly undercut the protection the LLC is there to give.
Accounting help. Cheaper than the first sales tax mistake. An hour with a local bookkeeper before you open, with your receipts in a folder and your questions on one page, usually saves more than it costs. Ask about sales tax, estimated payments and how to pay yourself, and write the answers down.
Customers. The line nobody budgets. You can be filed, licensed, insured and squared away, right down to the legal pages your website is supposed to carry, and still sit next to a phone that doesn’t ring. None of that paperwork shows up when a neighbor searches for what you sell, or asks ChatGPT who to call. That isn’t a flaw in you. It’s the old idea that a website plus a Google listing means people will see you. You’re not broken. You’re invisible, and that part is fixable.
That’s where a Gold listing on St Louis Near Me Directory earns its keep: up to 10 categories across up to 40 location tags, no public address required, so a kitchen-table or truck-based business can show up where neighbors look. It doesn’t replace the website or Google profile you already have. It points people to them.
The paperwork bill
How much money does it cost to open a small business?
Less than the formation sites charge. A Missouri LLC is $50 to file online with no annual report, while an Illinois LLC is $150 plus a $75 report every year. The IRS hands out an EIN for free, and a City of St. Louis business license is $200, or $100 if you open after January 1.
Can you skip the LLC altogether?
Often, yes, and the $50 isn’t the deciding factor. A sole proprietorship starts the moment you do business under your own name, which is where most people going solo as a freelancer in St. Louis begin. There’s no state formation filing for it. You still handle local licensing and taxes.
What the LLC buys is a line between business debts and personal property. That matters more when you work inside strangers’ homes, hire help, sign a lease or carry inventory. It matters less for a low-risk weekend side business. If you can’t tell which one you are, that’s a question for an attorney or accountant, asked once.
Before you spend a dollar on any of it, make sure somebody wants to buy. Our guide on testing a business idea before you spend money walks through it.
A realistic first-year floor in the City
One person, a Missouri LLC filed online, acting as your own registered agent, working inside City of St. Louis limits:
- LLC filing: $50
- EIN: $0
- Graduated Business License: $200, or $100 if you start after January 1
- Missouri annual report: $0, because there isn’t one
Add the $50 filing to the $100 or $200 license and you’re legal, before insurance and before a single customer. In Illinois, swap the $50 for $150 and add $75 every year. The cheap part is becoming legal. The part that decides whether you last is being the name people see when they need you. Refuse to be invisible.
Frequently asked questions
Do you have to pay for your LLC every year in Missouri?
Not to the State. The Missouri Secretary of State’s FAQ says limited liability companies do not have to file an annual report, so there is no yearly state fee for a Missouri LLC. Local business licenses are separate. In the City of St. Louis, the Graduated Business License renews every year.
How much does it cost to get a business license in Missouri?
Missouri licenses businesses at the city or county level, so the price depends on where you operate. Inside the City of St. Louis, a new Graduated Business License costs $200.00, or $100.00 if you start after January 1 and up to May 31. Renewals are priced by your number of St. Louis employees, owners included.
What is needed for an LLC in Missouri?
Articles of organization filed with the Secretary of State, $50.00 online or $105.00 on paper, and a registered agent. An agent may be an individual who is a Missouri resident and whose business office is identical with the registered office, and for a one-person shop that individual can be you. An EIN from the IRS is free.
Can I run my business without an LLC?
Yes. A sole proprietorship needs no state formation filing, though a trade name needs a $7 fictitious name registration and a City business still needs its license. You can also list it on St Louis Near Me Directory without an LLC; a Gold listing needs no public address.
At what point would I need an LLC?
When the risk grows: working inside customers’ homes, hiring help, signing a lease or holding inventory. An LLC puts a line between business debts and personal property. If you’re unsure, one conversation with an attorney or accountant settles it.
Is there any downside to having an LLC?
Some paperwork and discipline. You keep business money separate, and in Illinois you pay a $75 annual report every year. In Missouri there is no annual report to file, so the main downside is the habit of keeping things separate.
You filed for fifty dollars. Now make sure the neighbors can see you. Run the free audit and see who the AI names instead of you, then start the Gold plan: $357 a year, under a dollar a day, with a 7-day trial and no charge until day 8.
