By Jake Lawson, LLC Formation Strategist
Getting an EIN for your Missouri LLC costs nothing and takes 10 minutes online. Yet I regularly meet Kansas City and St. Louis entrepreneurs who paid $300+ to companies that simply filled out the same free IRS form you can complete during a coffee break.
Missouri’s central location and business-friendly attitude attract plenty of legitimate entrepreneurs—and unfortunately, plenty of scammers too. These companies create official-looking websites, charge outrageous fees, and provide zero additional value beyond what the IRS offers for free.
I’ve helped 190+ Missouri LLC owners get their EINs over the past decade, and I’m going to show you exactly how to do it right—plus the Missouri-specific considerations that can save you time and money as you build your business in the Show-Me State.
What Is an EIN and Why Missouri LLCs Need One
An EIN (Employer Identification Number) is your LLC’s federal tax identification number—essentially your business’s Social Security number. The IRS assigns this 9-digit identifier to your LLC for all federal tax reporting and business identification purposes.
Don’t get confused by the name: “Employer” doesn’t mean you need employees. Every business entity—even single-member LLCs with no employees—benefits from having an EIN.
Your Missouri LLC needs an EIN for:
- Opening business bank accounts (absolutely required)
- Filing federal tax returns
- Filing Missouri corporate income tax returns
- Registering with Missouri Department of Revenue for sales tax
- Applying for business credit cards or loans
- Setting up payroll systems if you hire employees
- Building business credit separate from personal credit
- Professional credibility with Missouri vendors and clients
- Qualifying for Missouri business incentives and programs
What makes Missouri different:
- State corporate income tax for LLCs (unlike some states)
- Missouri Department of Revenue registration requires federal EIN
- Strong banking infrastructure expects proper documentation
- Growing tech and agriculture sectors with specific requirements
The EIN Scam Problem in Missouri: Don’t Get Fooled
Missouri’s growing business community attracts EIN scammers who prey on new entrepreneurs. These companies spend heavily on Google ads to appear when you search for Missouri EIN information, then charge you for services the IRS provides free.
Common Missouri EIN scam tactics:
- “Missouri EIN specialists” claiming special knowledge of state requirements
- Websites designed to look like official Missouri government sites
- “Express Missouri EIN processing” (all EINs are processed identically)
- Claims that Missouri LLCs need special handling
- Bait-and-switch pricing that adds “Missouri compliance fees”
Red flags to watch for:
- Any website charging for EIN services
- Claims about “complex Missouri requirements”
- “Expedited processing” for additional fees
- Websites that aren’t IRS.gov asking for payment
- “Professional assistance required” for Missouri LLCs
Jake’s Missouri rule: The IRS doesn’t care whether you’re in Kansas City, St. Louis, or Branson—all EINs are free and straightforward to get online. Don’t let scammers exploit Missouri’s business growth to separate you from your money.
Missouri LLC EIN Timing: Critical Sequence
STOP: Do not apply for an EIN until the Missouri Secretary of State officially approves your LLC.
This timing mistake costs Missouri entrepreneurs weeks of delays and complications. Here’s the correct sequence:
Step 1: File Articles of Organization with Missouri Secretary of State
Step 2: Wait for approval (typically 1-3 business days for online filing)
Step 3: Verify your LLC appears in Missouri business entity search
Step 4: THEN apply for EIN using exact approved LLC name
Why this sequence matters in Missouri:
- Missouri banks are thorough about name matching
- IRS verifies business existence before issuing EIN
- Missouri Department of Revenue registration requires exact name matching
- Errors delay your ability to start business operations
