What It Takes to Start a Business in Missouri
Missouri is home to more than 540,000 small businesses, representing 99.5% of all employers in the state. Filing an LLC costs just $50 online, and the state charges no franchise tax on LLCs, making it one of the more affordable states for new founders.

The state does not require a general business license at the state level, though most cities and counties have their own licensing requirements. This guide walks you through each step from validating your idea to staying compliant after formation.
Validate Your Business Idea
Research demand for your product or service before investing time and money. Missouri's strongest industries include:
- Advanced manufacturing and aerospace (Boeing, headquartered in the St. Louis metro)
- Agriculture and food processing (Missouri ranks in the top 10 nationally for cattle and soybean production)
- Financial services and insurance (major employers in Kansas City and St. Louis)
Contact the Missouri Small Business Development Center (SBDC) for free one-on-one consulting and market research assistance. They offer no-cost business assessments at locations across the state.
Pro Tip
Write a Business Plan
A business plan is required if you seek bank financing or SBA loans, and it forces you to think through revenue, expenses, and competition. Include financial projections for at least 12 months, a customer acquisition strategy, and a clear description of your product or service.
Follow our step-by-step business plan guide to build a plan that satisfies lenders and investors. Keep the document concise and update it quarterly as your business grows.
Pro Tip
Choose Your Business Structure
Most founders in Missouri choose an LLC because it combines personal liability protection with pass-through taxation and has no franchise tax. Filing an LLC costs $50 online at the Missouri Secretary of State.
The four main structures are sole proprietorship, LLC, S-Corp, and C-Corp. Each has different tax treatment, liability exposure, and paperwork requirements. See the full comparison below, or read our Missouri LLC formation guide for detailed instructions.
Pro Tip
Business Structure Comparison — Missouri
Full comparison guide| Structure | Missouri Filing Cost | Personal Liability | How You're Taxed | Best For |
|---|---|---|---|---|
| Sole Proprietorship | $7 (DBA) | ❌ None | Personal income tax. No separate return. | Freelancers, consultants, side hustles testing an idea with no employees. |
| LLC Most Common | $50 online | ✅ Personal assets protected | Pass-through by default. Elect S-Corp when profitable. | Most small businesses. Best balance of liability protection, flexibility, and tax options. |
| S-Corporation | ~$50 + IRS election | ✅ Personal assets protected | Pass-through. Owners pay themselves a salary — can reduce self-employment tax. | Profitable businesses (typically $50K+ net) where payroll tax savings justify the complexity. |
| C-Corporation | $58 | ✅ Personal assets protected | Corporate tax rate (21% federal). Double taxation on dividends. | Startups planning to raise VC funding, issue stock options, or eventually go public. |
| General Partnership | Free / No State Filing | ❌ None — all partners personally liable | Pass-through. Each partner reports share on personal return. | Two or more owners who trust each other and don't need liability protection. |
Which should you choose? Most first-time founders in Missouri pick an LLC — it protects your personal assets without the complexity of a corporation. If you're not sure, consult a CPA or business attorney before filing. Read the full Missouri LLC guide →
Choose and Register Your Business Name
Your business name must be distinguishable from every other entity on file with the Missouri Secretary of State. Search the Missouri business name database to confirm availability before filing.
LLCs must include "LLC" or "Limited Liability Company" in the official name. You can reserve a name for 60 days for $25, renewable twice for a total hold of 180 days.
Pro Tip
Check Missouri Business Name Availability
Search the official Missouri Secretary of State database before you file.
Register Your Business with the State
File your Articles of Organization online at the Missouri Secretary of State's business portal for $50. Standard processing takes 3 to 5 business days, and same-day or next-day expedited processing is available for an additional fee.
You will need a registered agent with a physical Missouri address. The state will mail your Certificate of Organization once approved. See our Missouri registered agent guide for affordable options starting at $0 (self-designation) up to $125 per year for professional services.
Pro Tip
Important
File Online with Missouri Secretary of State
Official Missouri business registration portal. Standard processing: 3-5 business days.
Get Your Federal EIN
Apply for a free Employer Identification Number (EIN) directly from the IRS online portal. The process takes about 10 minutes and you receive your EIN immediately upon completion.
An EIN is required to open a business bank account, hire employees, and file federal taxes. Never pay a third party for EIN filing because the IRS provides it at no cost.
Pro Tip
Get Your Licenses and Permits
Requirements vary by industry and location, but most Missouri businesses need some combination of the following:
- Sales Tax License — required if selling taxable goods or services; register free at the Missouri Department of Revenue
- Local Business License — required by most cities and counties (Jefferson City, Kansas City, and St. Louis each have their own licensing offices with fees ranging from $50 to $300)
- Professional License — required for contractors, real estate agents ($100 application fee), pharmacists ($150), chiropractors ($200), and other regulated fields through the Missouri Division of Professional Registration
- Employer Registration — register with the Missouri Department of Labor before hiring your first employee
Pro Tip
Important
Open a Business Bank Account
Bring your EIN confirmation letter, Articles of Organization, government-issued ID, and your LLC operating agreement to the bank. Separating personal and business finances is essential for maintaining your LLC's liability protection.
Compare fee structures and features in our best business bank accounts guide. Many online banks offer free business checking with no minimum balance requirements.
Pro Tip
Set Up Accounting and Understand Your Taxes
Missouri's individual income tax ranges from 1.5% to 5.3% across graduated brackets, and LLC profits pass through to your personal return. The state sales tax rate is 4.225%, though combined local rates can push the total above 10% in some jurisdictions.
Register with the Missouri Department of Revenue to collect sales tax and file state income taxes. Set aside money quarterly for estimated federal and state tax payments to avoid penalties.
Use cloud accounting software to track income and expenses from day one. Our best accounting software guide compares top options for new businesses.
Pro Tip
Important
Get Business Insurance
Missouri requires workers' compensation insurance for all employers with 5 or more employees (construction employers need coverage with 1 or more). General liability insurance is the baseline policy every business should carry, regardless of industry.
Compare coverage options in our best business insurance guide. Many insurers offer bundled Business Owner's Policies (BOPs) that combine general liability and property coverage at a discount.
Pro Tip
Build Your Online Presence
Claim your free Google Business Profile immediately to appear in local search results across Missouri. This is the single highest-ROI action for local businesses, especially in metros like Kansas City, St. Louis, and Springfield.
Build a simple website with your services, pricing, and contact information. Our best website builders guide covers beginner-friendly platforms starting at under $20 per month.
Pro Tip
Stay Compliant After Forming
After forming, keep your Missouri business in good standing by meeting these ongoing requirements:
- No annual report, Missouri asks an LLC for nothing after formation. There is no LLC annual report, no annual registration and no renewal fee at the Secretary of State.
- State Tax Filings — file annual state income tax returns and quarterly sales tax returns with the Missouri Department of Revenue
- Registered Agent — maintain a registered agent with a physical Missouri address at all times
- Business Licenses — renew any city or county licenses annually (DBA filings renew every 5 years for $7)
The annual registration report founders hear about is a corporation filing under section 351.120 of the Missouri statutes. Chapter 347, which governs limited liability companies, has no equivalent, so the dates worth tracking here are tax and licence dates rather than a Secretary of State renewal.

Missouri Business Background & Context
State-specific data to help you plan — taxes, economy, funding, and what to expect after you form.
Missouri charges just $50 to form an LLC online, which is among the lowest filing fees in the country. The state imposes no franchise tax or privilege tax on LLCs, keeping ongoing costs minimal.
The state's central location provides ground-shipping access to 90% of the U.S. population within two days. Kansas City and St. Louis both serve as major logistics and distribution hubs with extensive rail, highway, and air freight networks.
Missouri's cost of living is approximately 15% below the national average, which translates to lower wages, office rents, and operational expenses. The median commercial rent in Missouri is well below comparable spaces in coastal metros.
Two major metro areas (Kansas City and St. Louis) each offer distinct talent pools and customer bases without the overhead of tier-one coastal cities. Springfield and Columbia add secondary markets with strong university pipelines.
The state has invested heavily in startup ecosystems through organizations like the Missouri Partnership and Cortex Innovation Community in St. Louis. Access to early-stage capital continues to grow through regional venture funds and angel networks.
Missouri Business Climate
Missouri's graduated income tax tops out at 5.3%, and the legislature has been gradually reducing the top rate in recent years. Combined with no franchise tax for LLCs, the total state tax burden is moderate compared to neighboring Illinois and Kansas.
The state ranks in the top 15 nationally for business-friendliness according to the Tax Foundation's State Business Tax Climate Index. Regulatory requirements are straightforward, with no general state business license requirement.
Missouri's unemployment insurance tax rate for new employers starts at approximately 2.376% on the first $10,500 in wages per employee. This rate adjusts based on your claims history after your first year of operation.
Broadband infrastructure investment and workforce development programs have expanded significantly, particularly through Missouri One Start, which provides free customized training for new and expanding businesses.
Advanced Manufacturing and Aerospace employs over 250,000 workers statewide. Boeing, Emerson Electric, and numerous defense contractors anchor this sector in the St. Louis corridor.
Healthcare and Life Sciences is anchored by major research institutions including Washington University School of Medicine and the Stowers Institute in Kansas City. Biotech startups have access to specialized incubators in both metros.
Agriculture and Food Processing generates more than $93 billion annually in economic output. Missouri ranks in the top 10 nationally for cattle, soybeans, corn, and hog production.
Financial Services and Fintech thrive in Kansas City, home to major financial institutions and a growing fintech startup ecosystem. The sector employs tens of thousands across the metro area.
Logistics and Transportation benefits from Missouri's central geography, with Interstate highways I-70, I-44, and I-55 converging in the state. Kansas City is one of the largest rail hubs in North America.
Technology and IT Services are growing in both the St. Louis and Kansas City corridors, with tech employment increasing at roughly twice the national average in recent years.
Missouri's individual income tax uses graduated brackets ranging from 1.5% to 5.3%. LLC profits flow through to your personal return, so the rate you pay depends on your total taxable income.
The state sales tax rate is 4.225%, but local jurisdictions add their own taxes. Combined rates in Kansas City and St. Louis can exceed 10%, so check the exact rate for your business location at the Missouri Department of Revenue.
Missouri charges no franchise tax and no privilege tax on LLCs. This is a significant cost advantage over states like California ($800 minimum) and Texas (margin tax).
The annual LLC registration fee is $50, due between January 1 and April 1 each year. This is the only mandatory annual state payment for a Missouri LLC with no employees.
Self-employed individuals owe 15.3% federal self-employment tax on net earnings (12.4% Social Security and 2.9% Medicare). Electing S-Corp tax treatment can reduce this burden once your business earns enough to justify a reasonable salary.
Missouri conforms to most federal tax provisions, so federal deductions like the Qualified Business Income (QBI) deduction generally apply on your state return as well. Consult a CPA to maximize deductions specific to your industry.
Missouri's cost of living index is approximately 85.9 (U.S. average = 100), making it one of the more affordable states for both living and operating a business. Office space in Kansas City averages $18 to $22 per square foot, roughly half the cost of comparable space in Chicago.
The state minimum wage is $12.30 per hour as of 2024, with scheduled increases ahead. Average wages across all industries are approximately 10% below the national median, which helps startups manage payroll costs during early growth.
Residential and commercial electricity rates in Missouri average around $0.11 per kWh, below the national average of $0.13. Utility costs are consistently lower than both coastal states and many Midwest neighbors.
The Missouri Small Business Development Center (SBDC) offers free consulting, market research, and help with SBA loan applications at locations statewide. They assisted Missouri businesses in securing hundreds of millions in capital last year alone.
The SBA Kansas City District Office and the SBA St. Louis District Office serve Missouri founders with loan guarantee programs, including the popular SBA 7(a) and 504 loan programs. Microloans up to $50,000 are also available through SBA-approved intermediaries.
Missouri offers tax credits and incentive programs through the Missouri Department of Economic Development, including the Missouri Works program which provides state tax credits for job creation. The BUILD Missouri program offers financing for small businesses in underserved areas.
The Cortex Innovation Community in St. Louis and the KC Digital Drive in Kansas City both provide startup accelerator programs and connections to angel investors and venture capital. Several Missouri-based funds specifically target seed-stage and Series A companies.
In your first 30 days, open your business bank account, register for state sales tax at the Missouri Department of Revenue, and secure any required local business licenses. Set up accounting software immediately so every transaction is tracked from day one.
By day 60, obtain business insurance (including workers' comp if you have 5 or more employees) and establish your online presence with a Google Business Profile and basic website. If you plan to hire, register with the Missouri Department of Labor for unemployment insurance.
By day 90, file your first estimated tax payment if applicable and review your business plan against actual results. Missouri has no LLC annual report, so there is no Secretary of State renewal to diary, only your tax and licence dates.
