What It Takes to Start a Business in Missouri
Missouri offers a low-cost, business-friendly environment with graduated income tax rates from 1.5% to 5.3% and no franchise tax for LLCs. You can file your formation documents online through the Missouri Secretary of State and receive approval in as few as 3 to 5 business days.
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 $30, 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.
