Just launched your Indiana LLC? Outstanding choice—you’ve established your business in the Hoosier State, one of the most business-friendly and centrally located states in America. But here’s what every Indiana entrepreneur needs to understand: getting your EIN (Employer Identification Number) is your next essential step, and it’s much simpler than most people realize.
After helping dozens of Indiana business owners from Indianapolis to Evansville navigate the EIN process, I can tell you this: the IRS makes it straightforward and completely free, but there are Indiana-specific considerations that can catch Crossroads of America businesses off guard. Let me walk you through everything you need to know.
What Is an EIN and Why Your Indiana LLC Must Have One
Think of an EIN as your business’s Social Security Number for the federal government. It’s a unique 9-digit identifier (formatted XX-XXXXXXX) that distinguishes your LLC from millions of other business entities nationwide.
Don’t be confused by “Employer” in the name—you don’t need employees to get an EIN.
Your Indiana LLC Needs an EIN to:
- Open business bank accounts (absolutely required by all financial institutions)
- File federal tax returns and Indiana state tax returns
- Apply for business credit cards and commercial financing
- Obtain Indiana business licenses and local permits
- Register for Indiana sales tax with the Department of Revenue
- Set up payroll systems when hiring employees
- Establish business credit separate from your personal credit
- Protect your personal Social Security Number from business exposure
Jake’s reality check: I’ve seen Indiana entrepreneurs try to operate using only their SSN, especially in smaller communities throughout the state. This creates tax complications, limits banking options, and exposes you to identity theft—a growing concern even in Indiana’s traditionally tight-knit business communities.
Indiana EIN vs Indiana Tax ID: Know the Difference
This distinction confuses many new Indiana business owners:
Federal EIN (what we’re covering here):
- Issued by the IRS for federal tax identification
- Used nationwide for business identification
- Required for banking and federal compliance
- Always free directly from the government
Indiana State Tax ID:
- Issued by Indiana Department of Revenue
- Required for Indiana state taxes and business registrations
- Separate application process from federal EIN
- Different numbering system from your EIN
You’ll need both for complete Indiana business compliance. They serve different purposes and come from different government agencies.
The Great News: EINs Are Always Free
Absolute fact: The IRS never charges for EINs. Ever. It’s a free government service, like getting a hunting license.
Major scam warning: Ignore any website charging $50-$500 for “EIN processing services” or “expedited filing.” These are predatory companies selling you something the government provides free. I’ve seen Indiana business owners pay $350 for a 15-minute process that costs nothing.
Red flags to watch for:
- Websites designed to look like IRS.gov but aren’t official
- “Guaranteed instant approval” promises (most applications are approved automatically)
- Rush processing fees (online applications provide instant results)
- Upfront payment requirements before any services
- Cold calls claiming “EIN renewal” is required (EINs don’t expire)
Perfect Timing for Your Indiana EIN Application
Critical rule: Wait until your Indiana LLC is officially approved by the Indiana Secretary of State before applying for your EIN.
Why timing matters:
- IRS requires your exact LLC name as approved by Indiana
- Premature applications create complications if your name gets modified during state approval
- Name mismatches trigger IRS reviews and potential processing delays
- Indiana processing times can vary by filing volume and season
My recommended timeline:
- File your Indiana Articles of Organization with the Secretary of State
- Wait for official approval confirmation (typically 5-15 business days)
- Apply for EIN using the exact approved LLC name
- Begin Indiana state tax registrations and business banking immediately
What if you applied too early? Don’t panic. If your LLC gets approved with the identical name you used on your EIN application, you’re fine. Name changed? You’ll need to apply for a new EIN.
Step-by-Step EIN Application Process
For US Citizens and Residents (SSN/ITIN Holders):
Apply online at IRS.gov—it’s the fastest, most reliable method available.
Essential Information to Gather:
- Your Indiana LLC approval documents
- Social Security Number or Individual Taxpayer Identification Number
- LLC formation date and state (Indiana)
- Principal business address (anywhere in Indiana)
- Responsible party information (typically you as the LLC owner)
- Clear description of your business activities
- Expected number of employees (zero is perfectly acceptable)
The Online Application Process (15-20 minutes):
Step 1: Navigate to IRS.gov and search “Apply for EIN Online”
Step 2: Select “Limited Liability Company (LLC)” as your entity type
Step 3: Enter LLC information exactly as shown on Indiana documents
Step 4: Provide responsible party details (person authorized to receive tax information)
Step 5: Answer business activity questions accurately but concisely
Step 6: Review all information meticulously and submit application
Instant results: You’ll receive your EIN immediately upon approval and can download your official EIN Confirmation Letter (CP 575) right away.
For Non-US Residents (No SSN/ITIN):
You must apply by mail or fax using Form SS-4.
Required Documentation:
- Completed Form SS-4 (Application for Employer Identification Number)
- Copy of your Indiana LLC approval documents
- Copy of passport or government-issued photo identification
- Valid US mailing address for IRS correspondence
- Cover letter explaining your non-resident status and business purpose
Processing Timeline:
- Mail application: 4-6 weeks typical processing time
- Fax application: 4-5 business days to (855) 641-6935
- Eastern Time Zone: Indiana businesses benefit from convenient IRS processing hours
Jake’s tip for international entrepreneurs: Consider obtaining an ITIN first, which enables online EIN applications. While it adds a preliminary step, it dramatically speeds up your overall business setup process.
Common Indiana LLC EIN Mistakes
Mistake 1: Wrong Entity Type Selection
The error: Selecting “Corporation” instead of “Limited Liability Company” The consequence: IRS processing delays and incorrect federal tax classification The prevention: Always carefully select “Limited Liability Company” for all LLC applications
Mistake 2: Using Trade Names Instead of Legal Names
The error: Applying with your DBA or trade name rather than registered LLC name
The consequence: EIN gets associated with incorrect entity
The solution: Use exactly the name appearing on your Indiana Articles of Organization
Mistake 3: Rushing the Application Process
The error: Applying before Indiana Secretary of State officially approves your LLC
The consequence: Name discrepancies and potential compliance complications
The fix: Practice patience—wait for official Indiana approval confirmation
Mistake 4: Incorrect Responsible Party Information
The error: Listing someone without legal authority to bind the LLC The consequence: Future IRS compliance and communication problems The correction: List an LLC member or manager with actual legal authority
Single-Member vs Multi-Member Indiana LLCs
Single-Member LLCs:
Federal tax treatment: Disregarded entity (taxed like sole proprietorship) EIN requirement: Technically optional, but practically essential Key benefits: Banking access, identity protection, business credibility Indiana specifics: Still may be subject to Indiana business taxes
Multi-Member LLCs:
Federal tax treatment: Partnership taxation (unless you elect corporate treatment) EIN requirement: Absolutely mandatory per federal tax regulations Tax obligations: Must file Form 1065 partnership return annually Indiana requirements: Additional state partnership tax filings required
Married Couples in Indiana:
Important clarification: Indiana is NOT a community property state, so married couples have limited options:
- Standard approach: Multi-member LLC with partnership taxation
- Not available: Qualified Joint Venture election (reserved for community property states)
Professional guidance: Consult with an Indiana tax professional about the most advantageous structure for your specific business situation and Indiana’s tax landscape.
Your EIN Confirmation Letter: Protect It Like Gold
After approval, you’ll receive an EIN Confirmation Letter (CP 575)—one of your most critical business documents.
Absolutely Essential For:
- Opening all business bank accounts in Indiana
- Applying for business credit cards and commercial loans
- Filing federal and Indiana state tax returns
- Obtaining Indiana business licenses and local permits
- Registering for Indiana sales tax with Department of Revenue
- Setting up merchant accounts and payment processing
- Establishing vendor relationships and business contracts
If You Lose Your CP 575:
Critical information: You cannot obtain another CP 575 from the IRS. However, you can request an EIN Verification Letter (147C), which serves the same purpose for virtually all business needs.
Protection strategy: Immediately save digital copies in multiple secure locations and maintain physical copies in your primary business filing system.
Opening Your Indiana LLC Bank Account
Next essential step: Establish dedicated business banking using your new EIN.
Required Documentation:
- EIN Confirmation Letter (CP 575)
- Indiana Articles of Organization
- Operating Agreement (especially important for multi-member LLCs)
- Personal identification for all authorized signers
- Initial deposit (varies by financial institution)
Indiana Banking Landscape:
Regional leaders: Old National Bank, First Merchants Bank (strong Indiana presence and local expertise) Indianapolis-focused: Indiana Members Credit Union, Teachers Credit Union (excellent member service) National banks: Chase, PNC Bank, Fifth Third (extensive branch networks throughout Indiana) Community banks: Centier Bank, German American Bank (personalized service and local decision-making)
Jake’s Indiana banking insight: Indiana’s banking market offers excellent choices for businesses. Regional banks often provide the best combination of local knowledge and competitive services, while community banks excel in personalized relationships for smaller businesses.
Indiana-Specific EIN Considerations
Indiana Business Taxes:
Indiana has various business taxes that may apply to LLCs. Your EIN is required for registration and filing with the Indiana Department of Revenue.
Sales Tax Registration:
Indiana requires sales tax registration for businesses selling taxable goods or services. Your EIN is essential for proper Department of Revenue registration.
Professional LLCs in Indiana:
Indiana allows Professional LLCs (PLLCs) for licensed professionals. The EIN application process is identical to regular LLCs.
Multiple Indiana Businesses:
Each separate LLC requires its own unique EIN. Never attempt to share EINs across different business entities.
Multi-State Business Operations:
If your Indiana LLC operates in multiple states (common given Indiana’s central location), you may need additional state registrations while using the same federal EIN.
Troubleshooting Common EIN Application Issues
“Cannot Complete Your Application Online” Error
Typical causes:
- SSN/ITIN verification problems with IRS databases
- Multiple previous EIN applications under the same SSN
- Technical issues with IRS online systems
Effective solutions:
- Verify all personal information matches IRS records exactly
- Call IRS Business & Specialty Tax Line: (800) 829-4933
- Consider mail/fax application as backup approach
Business Name Already Taken Error
If IRS claims your Indiana LLC name is unavailable:
- Double-check your Indiana Secretary of State documents for exact spelling
- Ensure you’re using the complete legal name, not abbreviated version
- Contact IRS directly if you believe there’s a database error
Lost or Incorrect EIN Information
For lost EINs: Request EIN Verification Letter (147C) from IRS For incorrect details: File Form 8822-B for address changes, call IRS for name corrections For Indiana address updates: Update both federal EIN records and Indiana state registrations
Professional Services vs DIY Approach
DIY Approach Makes Sense When:
- You have valid SSN or ITIN
- Your LLC structure is straightforward
- You’re comfortable with online government applications
- You want to save unnecessary service fees
- You have time to handle the administrative process personally
Consider Professional Help When:
- You’re a non-US resident without ITIN
- You have complex multi-member ownership structures
- You’ve made previous mistakes requiring corrections
- You prefer to delegate administrative tasks to experts
- Time has extremely high opportunity cost for your business
Cost reality check: Professional EIN services charge $150-$500 for something that’s completely free and takes 15 minutes. Only consider this if your time is extraordinarily valuable.
Post-EIN Essential Action Items
Immediate High-Priority Tasks:
